UHT Processing: Elevating Dairy Delights through Essential Stages
In the realm of dairy processing, Ultra High Temperature (UHT) stands as a complex and automated procedure, encompassing a series of stages that culminate in the creation of safe, top-notch, shelf-stable food products. This meticulously orchestrated journey involves crucial components like heating, flash cooling, homogenization, and aseptic packaging.
A cornerstone of food processing, heating elevates product temperature to specific levels required for processing, pasteurization, or sterilization. Within the UHT context, the journey begins with pre-heating the liquid to a non-critical temperature (70-80°C for milk) before rapidly ascending to the desired temperature.
Following the intense heat, flash cooling comes into play, rapidly restoring the product to lower temperatures. In UHT processing, flash cooling prevents overcooking, preserving the product's essential characteristics intact.
For dairy products like milk, homogenization is pivotal. This mechanical process dismantles fat globules, uniformly distributing them within the liquid. The result is a cohesive product that sidesteps the separation of cream from the liquid. Applied post-heating and pre-packaging, homogenization weaves harmony into the dairy delight.
At the pinnacle of the process, aseptic packaging emerges. This technique sterilizes both the product and the packaging materials separately, ensuring a pristine environment for filling and sealing. Through this meticulous method, product quality and freshness are sustained over extended periods, void of refrigeration or additional preservation tactics. The essence of UHT processing finds its zenith in aseptic packaging, as it guards against the intrusion of bacteria and other microorganisms that jeopardize the product's integrity.
Amidst the intricate ballet of UHT processing, these stages harmonize to deliver dairy delights that exude quality, safety, and longevity. With the aim of securing a prime position in the world of dairy processing, the UHT journey navigates multiple phases, each essential in perfecting the art of producing exceptional dairy products.
In the realm of pasteurization, two distinct approaches, direct and indirect heating, play crucial roles depending on the product and desired outcomes. While direct heating involves immediate contact with the heat source, indirect heating employs a heat transfer surface, such as a heat exchanger, to gently raise the product's temperature.
Within indirect heating systems, a solid heat exchanger, akin to those utilized in pasteurization, is employed to heat the product. However, at elevated temperatures, higher pressures must be applied to prevent boiling. Three types of exchangers are commonly employed:
Plate Heat Exchanger
Tubular Heat Exchanger
Scraped-surface Heat Exchanger
Among these options, the plate heat exchanger stands out as the most efficient choice. Leveraging pressurized water or steam as the heating medium, these plate exchangers maximize energy conservation through integrated regeneration units that facilitate medium reuse.

Let's explore these stages in detail, highlighting their significance in the context of milk plate heat exchangers and their role in the broader heat exchangers used in the dairy industry.
The foundation of sterilized milk quality rests upon the quality of raw milk. Rigorous management and meticulous testing of raw milk are indispensable to uphold its standards. Only raw milk meeting specified criteria earns its place in producing sterilized milk.
Milk filtration and purification take center stage to eliminate dust and impurities, ensuring pristine milk quality. These processes align harmoniously with the efficiency of dairy plate heat exchangers, working collectively to purify the milk.
Achieving milk's desired fat content is essential for standardized quality. Across different nations, standards vary, with low-fat milk containing around 0.5% fat, and typical milk containing 3%. Notably, China mandates 3.0% fat content for sterilized milk, necessitating meticulous standardization.
This step, executed at a consistent temperature of 65°C and pressure of 10 to 20 MPa, refines milk's consistency. The synchronized role of plate heat exchangers in dairy processes contributes to the successful homogenization, optimizing milk attributes.
Heat sterilization emerges as a pivotal method to combat potential microbial risks in pasteurized fresh milk. The harmonious interplay of heat exchangers in dairy processes ensures effective sterilization, bolstering milk's stability during storage, combating rancidity, and arresting microorganism growth.
Inhibiting bacterial proliferation and extending milk's shelf life, cooling is pivotal. Whether cooling milk to approximately 4°C or efficiently handling ultra-high temperature milk, heat exchangers' contribution is central to maintaining optimal temperatures.
Filling marks the final stage, poised to preserve milk's integrity. From glass bottles to plastic containers, each filling vessel serves as a guardian of milk's essence. Heat exchangers play an integral role in sustaining the temperature integrity of filled containers.
Amidst this intricate symphony of processes, the significance of milk plate heat exchangers in dairy production stands pronounced. These heat exchangers align harmoniously with broader heat exchangers in the dairy industry, culminating in the production of premium sterilized milk.
When considering dairy processing, the plate heat exchanger assumes a pivotal role in achieving optimal results. This case study delves into the application of HTST pasteurization utilizing a plate heat exchanger in a stepwise manner.
In the first phase, the pre-cooled 5°C fresh milk engages with the plate heat exchanger in the heat recovery section, absorbing heat to reach approximately 65°C. This initial step sets the foundation for subsequent stages.
The plate heat exchanger ensures precise heat treatment during the sterilization phase. This strategic utilization of heat ensures the elimination of potential contaminants while maintaining the integrity of the milk.
The final step involves the plate heat exchanger, where ice water serves as the cooling medium. The milk, having undergone pasteurization, is effectively cooled to preserve its quality.
Throughout the process, the plate heat exchanger in dairy industry not only facilitates the efficient exchange of thermal energy but also underscores the importance of precision in dairy processing. The integration of advanced heat exchangers in dairy industry safeguards the product's safety and quality.
In conclusion, the utilization of a plate heat exchanger in the HTST pasteurization of dairy products exemplifies the pivotal role of cutting-edge heat exchangers used in dairy industry. This case study underscores how innovative thermal solutions, such as the plate heat exchanger, contribute to the overall enhancement of dairy processing efficiency and product integrity.

The plate heat exchanger, which incorporates representatives for ice cream, is extensively utilized in the food industry. The ice cream production process comprises various steps such as sterilization, cooling, mixing, filling, and packaging of the mixture.
Prior to homogenization, the temperature of the ice cream mixture must be meticulously controlled to range between 65ºC to 70ºC using the plate heat exchanger. Deviations from this range can lead to the condensation of fat or a foul odor. Subsequently, the plate heat exchanger is utilized for sterilization prior to transferring the material to the ageing tank, which brings the material to the required temperature for aging.
Plate Heat Exchanger for Oil and Gas
Undoubtedly, oil and gas play a vital role in the contemporary human society. As these exhaustible natural resources continue to be utilized, the level of competition in this sector has intensified.
HFM has demonstrated its commitment to enhancing energy efficiency for our oil and gas associates through our custom-designed solutions, including oil heat exchanger and gas heat exchanger. These plate heat exchangers for oil and gas applications are engineered to facilitate optimal heat transfer between fluids, resulting in superior yield results and cost reduction for our partners in the oil and gas industry.
A heat exchanger is an equipment designed to transfer heat efficiently between two different mediums, which can either be in direct contact or separated by a solid wall to prevent mixing. This device finds wide applications in various industries, including space heating, refrigeration, air conditioning, power generation, chemical, petrochemical, natural gas processing, and sewage treatment.
The petroleum refining industry is a classic example of the utilization of heat exchangers. In this industry, crude oil is refined using fractional distillation to produce more useful petroleum products like gasoline, diesel fuel, heating oil, kerosene, asphalt base, and liquefied petroleum gas.
The separation of components of crude oil can be achieved by utilizing the differences in their boiling points. The process of fractional distillation involves heating the crude oil to vaporize it and then condensing the vapor at different levels of the distillation tower, depending on their boiling points. The resulting products are called fractions.
Heat exchangers play a crucial role in the preheating of feedstock in distillation towers and refinery processes, ensuring that they reach the required reaction temperatures. Heat exchangers use either steam or hot hydrocarbon transferred from other parts of the process as heat input. A fraction obtained from crude oil can be classified into two categories: Refined Products and Petrochemical Products.
Refined Products are fractions containing a variety of individual hydrocarbons, including gasoline, asphalt, waxes, and lubricants. On the other hand, Petrochemical Products are fractions consisting of one or two specific hydrocarbons of high purity, such as benzene, toluene, and ethylene.

The refining of crude oil entails a series of intricate stages to yield valuable resources. These stages comprise desalination in desalters, atmospheric distillation in crude distillation unit (CDU), vacuum distillation in Vacuum Distillation Unit (VDU), and others.
Of particular importance among these processes is the utilization of oil heat exchangers and gas heat exchanger, to facilitate the heating or cooling of the mixture to their optimum temperature, enabling the chemical reactions to occur efficiently.
Crude oil often contains water, inorganic salts, suspended solids, and water-soluble trace metals. To reduce corrosion, plugging, and fouling of equipment these contaminants must be removed by desalting (dehydration). This is done in desalters.
Crude oil must first be desalted, by heating to a temperature of 100-150 °C and mixing with 4-10% fresh water to remove inorganic salts (primarily sodium chloride). If these salts and heavy metals are not removed, they can form acids when heated, causing corrosion of downstream process equipment. Salts can also form deposits, causing plugging of heat exchangers or clogging trays in process towers. Crude oil exits from the desalter at temperature of 250 °C-260 °C.
Atmospheric distillation or the crude distillation is the first and most fundamental step in the the refining process. The primary purpose of the atmospheric distillation tower is to separate crude oil into its components (or distillation fractions) for further processing by other processing units.
Atmospheric distillation typically sets the capacity limit for the entire refinery. All crude oil processed must first go through atmospheric distillation. Also, atmospheric distillation typically provides most of the feed for the other process units in the refinery.
Following the desalter, the crude oil is further heated by exchanging heat with some of the hot, distilled fractions and other streams. It is then heated in a fuel-fired furnace (fired heater) to a temperature of about 398 °C and routed into the bottom of the distillation unit.
The heated crude is injected into the lower part of the distillation column, where much of it vaporizes. As the vapors rise through the tower, they pass through a series of perforated trays or structured packing.
The vapors from the top of the column are a mixture of hydrocarbon gases and naphtha, at a temperature of 120 °C-130 °C. The fractions removed from the side of the distillation column at various points between the column top and bottom are called sidecuts. Each of the sidecuts (i.e., the kerosene, light gas oil, and heavy gas oil) is cooled by exchanging heat with the incoming crude oil.
All the fractions (i.e., the overhead naphtha, the sidecuts, and the bottom residue) are sent to intermediate storage tanks before being processed further. The vapor stream associated with steam used at bottom of the column is condensed by the water cooler and the liquid collected in a vessel is known as reflux drum which is present at the top of the column. The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser.
Some part of the liquid is returned to the top plate of the column as overhead reflux, and the remaining liquid is sent to a stabilizer column which separates gases from liquid naphtha. A few plates below the top plate, the kerosene is obtained as product at a temperature of 190 °C-200 °C. Part of this fraction is returned to the column after it is cooled by a heat exchanger.
This cooled liquid is known as circulating reflux to contact with the rising vapors, helping to cool them. This effect of counter-current flows of rising vapors meeting falling cooler liquids allows equilibrium conditions to be established throughout the column. The lighter (less-dense) hydrocarbons will condense at higher points in the distillation tower, heavier hydrocarbons will condenser lower down.
This results in separation of the hydrocarbons based on the different temperatures at which they boil/condense. Hydrocarbons are drawn off the tower at different heights to get a set of streams of different boiling points. These different streams are called distillation cuts or fractions. These individual streams are then sent to other units for further processing or to finished product blending.
The remaining crude oil is passed through a side stripper which uses steam to separate kerosene. The kerosene obtained is cooled and collected in a storage tank as raw kerosene, known as straight run kerosene, that boils at a range of 140 °C-270 °C. A few plates below the kerosene draw plate, the diesel fraction is obtained at a temperature of 280 °C-300 °C. The diesel fraction is then cooled and stored.
The top product from the atmospheric distillation column is a mixture of hydrocarbon gases, e.g., methane, ethane, propane, butane, and naphtha vapours. Residual oil present at the bottom of the column is known as reduced crude oil (RCO). The temperature of the stream at the bottom is 340 °C-350 °C, which is below the cracking temperature of oil.
The pressure at the top of the distillation tower is maintained at 1.2-1.5 atm so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as atmospheric distillation column. In most refineries, the bottoms from the atmospheric distillation tower will be sent to the vacuum tower for further separation.
The fundamental purpose of the atmospheric tower is to separate fractions with boiling points lower than 350 ºC, including but not limited to gas, coal, and diesel. The atmospheric tower has a specific dimension of f6000x45335mm and is designed to feature a composite hole miniature fixed valve tray within its internal components. The tower comprises a total of 48 layers of trays, five of which belong to the stripping section.
Crude oil is a highly viscous substance, and its viscosity may lead to fouling and scaling on the heat transfer surfaces. To mitigate this, heat exchangers with plates that feature deep grooves are utilized to enhance heat transfer and minimize fouling.
Furthermore, temperature instability is a common challenge encountered in chemical processes, and heat exchangers must be designed to handle such conditions. In situations where the chemical system temperature is expected to exceed 100ºC, a fully-welded type heat exchanger is typically used.
This type of heat exchanger is designed to withstand high pressure and temperature and minimize the risk of leaks or failures. On the other hand, detachable plate heat exchangers with EPDM gaskets are a better option for lower temperatures, as they are more cost-effective and offer ease of maintenance.
In summary, heat exchangers are essential components of the oil refining process, and their proper selection and design are crucial to ensure efficient and safe operations. The type of heat exchanger utilized depends on the specific characteristics of the crude oil and the chemical system, including viscosity, temperature, and pressure.
Vacuum Distillation
Petroleum crude oil is a complex mixture of hundreds of different hydrocarbon compounds having from 3 to 60 carbon atoms per molecule, although there may be small amounts of hydrocarbons outside that range. The crude oil refining begins with distilling the incoming crude oil using atmospheric distillation operating at pressures slightly above atmospheric pressure.
In distilling the crude oil, it is important not to subject the crude oil to temperatures above 370 to 380 °C because the high molecular weight components in the crude oil will undergo thermal cracking and form petroleum coke at temperatures above that.
Formation of coke would result in plugging the tubes in the furnace that heats the feed stream to the crude oil distillation column. Plugging would also occur in the piping from the furnace to the distillation column as well as in the column itself.
The constraint imposed by limiting the column inlet crude oil to a temperature of more than 370 to 380 °C yields a residual oil from the bottom of the atmospheric distillation column consisting entirely of hydrocarbons that boil above 370 to 380 °C.
To further distilling the residual oil from the atmospheric distillation column, the distillation must be performed at absolute pressures as low as 10 to 40 mmHg (also referred to as Torr) to limit the operating temperature to less than 370 to 380 °C.
The primary advantage of vacuum distillation is that it allows for distilling heavier materials at lower temperatures than those that would be required at atmospheric pressure, thus avoiding thermal cracking of the components. Firing conditions in the furnace are adjusted so that oil temperatures usually do not exceed 380°C (716 °F).
Heavy distillates produced during the vacuum distillation process include light gas oil and heavy gas oil, which are then sent to the downstream separation and conversion units to be further refined into lube oil base stocks, or as feedstock for hydrocracking to produce light and middle distillates, such as jet fuel, kerosene, and diesel. Vacuum tower equipped with three padding sections, three layers of the oil sump tank, three combined liquid distributors, and metal mellapale packing on the first two layers and metal intalox saddle in the under layer.
The first vacuum side stream is exhausted from the first layer of the oil sump tank and cooled down to 80ºC after heat exchange, some of which flows out as product and some of which returns to the upper part of the first padding section as vacuum overhead reflux oil after being cooled down to 40ºC by the condenser.
The second vacuum side stream is exhausted from the second layer of the oil sump tank, one line of which is cooled down to 80ºC after heat exchange and flows out as a product, one of which returns to the upper part of the second padding section as vacuum overhead reflux oil and the other of which returns to the upper part of the third padding section as light wash oil with no need to be cooled.
Excess vaporization oil (third vacuum side stream) is exhausted from the third layer of the oil sump tank, some of which returns to the upper part of the third padding section as heavy wash oil, some of which mixes with the second vacuum side stream, enters into the integrated heavy oil line which is cooled down to 80ºC after heat exchange and flows out as product. Any residual oil leftover in the vacuum distillation column is transferred to the coker unit for further refining.
The 10 to 40 mmHg absolute pressure in a vacuum distillation column increases the volume of vapor formed per volume of liquid distilled. The result is that such columns have very large diameters.
Distillation columns may have diameters of 15 meters or more, heights ranging up to about 50 meters, and feed rates ranging up to about 25,400 cubic meters per day (160,000 barrels per day).
The vacuum distillation column internals must provide good vapor-liquid contacting while, at the same time, maintaining a very low pressure increase from the top of the column top to the bottom. Therefore, the vacuum column uses distillation trays only where withdrawing products from the side of the column (referred to as side draws).
Most of the column uses packing material for the vapor-liquid contacting because such packing has a lower pressure drop than distillation trays. This packing material can be either structured sheet metal or randomly dumped packing such as Raschig rings or other packing materials.
On the process mentioned above, there is a few oil heat exchanger application throughout the oil refining process.
Crude heat exchanger before desalination: crude oil of about 20-45 ºC flows into the heat exchanger and then into the electrical desalter after being heated up to 100-150 ºC.
Crude heat exchanger after desalination: desalted crude oil flows into the primary tower after heating up to 220-240ºC.
Primary distilled oil heat exchanger: After primary distillation, the oil flows into the heat exchanger and is heated to 270-280 ºC.
Primary overhead oil heat exchanger: the overhead oil gas is cooled down to 40ºC after passing through the overhead hot-water heat exchanger and air cooler and flows into the overhead reflux tank.
Overhead oil gas heat exchanger: the oil gas from the atmospheric overhead enters the return tank (Volume-103) for oil-water separation after cooling to 70 ºC by the air cooler.
Overhead oil-water cooler: Non-condensable oil gas is cooled down to 40 ºC by the condenser after entering the overhead product tank for oil-water separation.
First-line oil heat exchanger: the primary distilled oil, which is heated up to 370-380 ºC by the atmosphere furnace, flows into the first-line oil heat exchanger and is cooled down to 45ºC.
Second-line oil heat exchanger: the primary distilled oil, which is heated up to 370-380 ºC by the atmosphere furnace, flows into the second-line oil heat exchanger and is cooled down to 60-70ºC.
Third-line oil heat exchanger: the primary distilled oil, which is heated up to 370-380 ºC by the atmosphere furnace, flows into the third-line oil heat exchanger and is cooled down to 70ºC.

Plate Heat Exchanger for Brewing
Malting is the process of preparing cereal grains, such as barley, for brewing. It involves soaking the grains in water to initiate the germination process, followed by drying and heating to halt the process at a specific point.
The goal of malting is to activate enzymes within the grain that will later convert the starches into fermentable sugars during the brewing process. During germination, the grains produce enzymes that break down the complex carbohydrates into more manageable sugars, which are then utilized by the growing seedling. By stopping the germination process at a specific point, the maltster can control the level of enzymatic activity and the flavour and colour of the malt.
Malted grains are a key ingredient in beer brewing, providing fermentable sugars and contributing to the flavour, colour, and aroma of the finished product.
Milling is the process of crushing the malted barley (and other grains, if used) into a coarse powder, called grist, which is then mixed with water to extract the fermentable sugars. The main purpose of milling is to break open the husks of the malted barley to expose the starchy endosperm inside, which is what the yeast will consume during fermentation to produce alcohol and carbon dioxide.
The milling process typically involves feeding the malted barley into a machine called a malt mill, which uses a series of rollers to crush the grains. The rollers are adjustable to achieve the desired size of the grist, which can vary depending on the recipe and the type of beer being brewed. The grist is then stored in a grist hopper until it is needed for the next step in the brewing process.

Milling is the process of crushing the malted barley (and other grains, if used) into a coarse powder, called grist, which is then mixed with water to extract the fermentable sugars. The main purpose of milling is to break open the husks of the malted barley to expose the starchy endosperm inside, which is what the yeast will consume during fermentation to produce alcohol and carbon dioxide.
The milling process typically involves feeding the malted barley into a machine called a malt mill, which uses a series of rollers to crush the grains. The rollers are adjustable to achieve the desired size of the grist, which can vary depending on the recipe and the type of beer being brewed. The grist is then stored in a grist hopper until it is needed for the next step in the brewing process.
Gelatinisation is a crucial process in the production of beer as it converts starch into simpler sugars, such as glucose and maltose, which can be fermented by yeast to produce alcohol. The process involves mixing mashed malt or grains with water in a gelatinisation pot, which is a large metal container with hot water and steam inlets, and is equipped with devices such as stir bars, paddles or propellers, and temperature and control devices.
The mashed malt and water are heated and boiled in the gelatinisation pot, activating naturally occurring enzymes that break down the complex starch molecules into simpler sugars.
The temperature and duration of the boiling are carefully controlled to ensure that the starch is fully converted to sugars without causing any unwanted chemical reactions or flavors. Typically, the gelatinisation process takes place at temperatures ranging from 62-65°C (144-149°F) for 60-90 minutes.
Once the gelatinisation process is complete, the resulting liquid is called wort. The wort is then sent to a filtration vessel called a separation vessel. In the separation vessel, the wort is separated from the malt husk, and any other solids that may be present.
The separated wort is then pumped into a boiling pot, where hops and sugar are added to the mixture. The mixture is then boiled for a period of time, typically 60-90 minutes. The boiling process helps to dissolve the sugars and hops and also sterilizes the mixture by killing any microorganisms that may be present.
After boiling, the mixture is then pumped into a cooling tank, where it is rapidly cooled to a temperature of around 20°C (68°F) to facilitate fermentation. The cooled wort is then pumped into a fermentation vessel, where yeast is added to the mixture to initiate fermentation.
The gelatinization process typically involves heating the mixture of mashed malt and water in a gelatinization pot or vessel. The pot is often equipped with a heat exchanger to control the temperature and ensure even heating.
The brewery heat exchanger helps to maintain a consistent and controlled temperature during the gelatinization process, which is crucial for optimal starch conversion and enzyme activity. It also helps to prevent scorching or overheating of the mixture, which could negatively impact the flavour and quality of the final beer product.
Saccharification is the process that follows gelatinisation in the production of beer. During this process, the simple sugars that were created during the gelatinisation process are further broken down into fermentable sugars. This process is accomplished by adding enzymes, such as alpha and beta amylase, to the wort in a process called mashing.
Mashing typically takes place in a mash tun, which is a vessel that is designed to hold the grain and water mixture at a consistent temperature for a period of time. During the mash, the enzymes in the malted grain begin to break down the starches into sugars. The mash is typically held at a temperature range of 63-70°C (145-158°F) for 60-90 minutes, depending on the desired sugar profile of the beer.
The use of a heat exchanger is not typically necessary during the saccharification process, as the temperature is controlled by the mash tun. However, some modern breweries may use a heat exchanger to more precisely control the temperature of the mash or to speed up the process.
After the mash, the wort is transferred to a lautering vessel, where the remaining solids are separated from the liquid wort. The liquid wort is then boiled in a kettle along with hops and other ingredients to add flavour and aroma to the beer. During the boiling process, any remaining enzymes are denatured and the proteins in the wort are coagulated and removed.
Overall, the saccharification process is a crucial step in the beer-making process, as it helps to break down complex starches into simple, fermentable sugars that can be converted into alcohol by yeast.
Wort filtration or separation is an important step in the beer brewing process. It involves separating the liquid wort from the solids (grain husks, hops, etc.) that were used in the brewing process. This process is critical to the quality of the final beer product, as it removes unwanted flavours and aromas and helps to clarify the beer.
There are several methods of wort filtration/separation,
Lautering: This is the most common method of wort filtration used in commercial breweries. It involves transferring the wort from the mash tun to a vessel called a lauter tun, where the solids are separated from the liquid by gravity. The wort is then transferred to the boil kettle for further processing.
Filtration: This method involves passing the wort through a filter medium, such as diatomaceous earth or a membrane filter, to remove the solids. This method is commonly used in smaller breweries and home brewing setups.
