Design pasteurization

Types of design pasteurizations

Industrial-scale food processing equipment is essential for ensuring adequate food supply in the modern world. The core of many food processing lines is the machine that creates sterilized liquid food products: the machine with design pasteurization.

This machine is sometimes called a food pasteurizer, designed to eliminate pathogenic microorganisms from liquid food products by consistently heating them to a specific temperature for a given period of time. Additionally, pasteurization aims to preserve the nutritional value of the food product, subsequently increasing its shelf life and making it safer for people to consume.

There are several types of food pasteurizers, each appropriate for a specific kind of food product. The main distinction in the types of food pasteurizers is how heat exchangers combine heating and cooling components, which helps to raise and lower the temperature of the food product.

• Direct Systems: The heating and cooling elements are in the same vessel, such as in a batch pasteurization system. Batch pasteurization systems are typically used for food products that do not have any gas or high concentrations of sugar, such as milk. Design pasteurization batch is generally equipped with water jackets or hot water coils that surround the storage tank. The water heats the liquid food product up to a desired temperature and holds it there for a specific period of time before it is cooled down by the same cooling jacket or coils.
• Indirect Systems: The heating and cooling elements are in separate vessels, such as in a continuous pasteurization system. Continuous pasteurization systems are often preferred for food products with high productivity rates. Indirect systems typically have plate heat exchangers that use steam to heat the liquid food product. The processed liquid is cooled down using cold water in a plate heat exchanger as well.

Other specific types of food pasteurizers include:

• HTST food pasteurizer: This high-temperature, short-time food pasteurizer heats liquid food products at a high temperature for at least 15 seconds before immediately cooling it back down. The HTST food pasteurizer is the most popular type of food pasteurizer because it is both efficient and energy-saving. Not surprisingly, this machine is the mainstay of milk production lines worldwide.
• UHT food pasteurizer: An ultra-high temperature food pasteurizer heats the liquid food product at very high temperatures (at least 135°C) using tubular heating units. The UHT food pasteurizer produces an aseptic liquid food product. It is typically used for liquid food products such as fruit juices, liquid eggs, tomato puree, etc., that contain no preservatives and need to be stored for a long period of time in ambient conditions.
• Flash pasteurizer: A flash pasteurizer is another name for an HTST food pasteurizer. This machine heats the food product at high temperatures for a very short period of time before immediately cooling it down.
• Disc pasteurizer: A disc pasteurizer (also known as a plate pasteurizer) uses a combination of water and refrigerant to simultaneously heat and cool the liquid to be treated. Its compact design allows it to be easily integrated into production lines.
• Tub pasteurizer: A tub pasteurizer is usually cylindrical and larger in size. It operates using hot water as the heating medium. Tub pasteurizers are commonly used in large-scale processing facilities where high volumes of liquid need to be pasteurized efficiently.

Specifications and maintenance of design pasteurizations

Specifications of design Pasteurization vary based on the kind, capacity, and installed elements.

Components of a design Pasteurization and their specifications:

• Heat Source: It can be direct flame gas burners, electrical, steam coils, or other heat sources. The kind of heat source affects the temperature and efficiency of Pasteurization control systems.
• Pasteurization Unit: The main form of design Pasteurization, such as tubular, plate, or domed, has its capacity and heating efficiency.
• Temperature Control: Temperature control devices and sensors ensure that materials are heated to the specified temperature and maintained for a specific time to achieve effective Pasteurization. This control is crucial because it directly affects the ultimate goal and quality of design Pasteurization.
• Pressure Control: Some design Pasteurization require pressure control to ensure that the equipment operates at the appropriate pressure. Design Pasteurization that uses high-pressure techniques can have pressure control devices (like manometers, valves) that ensure that the pressure inside the equipment is in line with the requirements. This is very important for not just the effectiveness of Pasteurization but also safety.
• Cooling System: The cooling system of design Pasteurization equipment can be water-cooled or air-cooled. The choice of cooling method will affect the cooling efficiency and water consumption.
• Transmission System: Some design Pasteurization, like those using plate heat exchangers, may incorporate transmission systems for liquid, like pump units. The function and specifications of these systems will depend upon the kind and capacity of the equipment.

In addition, auxiliary systems in the design Pasteurization system, such as water treatment systems, refrigeration systems, cleaning systems, etc., may also have corresponding specifications. These auxiliary systems can help improve the efficiency and quality of Pasteurization.

Consider that the specifications of design Pasteurization equipment may change. Before deciding, thoroughly review the function and specifications of the equipment, and also consider your particular needs in use.

Due to the significance of design Pasteurization in food, milk, and beverage industries, maintenance of design Pasteurization is also critical. Regular maintenance can ensure the service life, efficiency, and safety of the equipment. Here are some standard maintenance techniques for design Pasteurization:

• Regular Inspection: Use tools like screwdrivers, pliers, etc. to check whether the screws, parts, and components of the design Pasteurization are loose, damaged, or worn. Fix or replace any components as required. Regularly inspect heat-exchange elements (like the tubes or plates in the heat exchanger) to ensure they are clean and not blocked.
• Cleaning: Clean the design Pasteurization equipment regularly. Wash the outside with water and detergent to keep it sanitary. Also, remove the residues inside of it, such as the heat-exchanging parts, to prevent the efficiency of heat exchange from reducing. Employ suitable cleaning agents and cleaning techniques according to the kind of material processed by the equipment to avoid cross-contamination.
• Paying attention to Electrical Components: Ensure that the electric parts of the design Pasteurization, such as temperature controllers and sensors, are operating correctly. Regularly inspect the batteries, wiring, and connections of electric components to ensure there is no corrosion or looseness.
• Regular Lubrication: Lubricate the moving parts of design Pasteurization (such as bearings and gear transmissions) periodically so that the equipment functions smoothly.
• Routine Calibrate: Check and calibrate various aspects, such as temperature controllers and pressure valves, to ensure their accuracy. Scheduled calibration can guarantee that design Pasteurization operates at optimal conditions, thereby enhancing its efficiency and product quality. Routine calibration also helps to familiarize operators with equipment performance and potential issues, allowing for timely adjustments and interventions.
• Routine Replacement: Replace filters and sealing components in auxiliary systems of design Pasteurization (like water treatment systems and refrigeration systems) on a scheduled basis to ensure system stability and performance.

Scenarios

There are many potential applications for design pasteurization machines. They are not just used in the dairy industry but also in different sectors and industries.

• Food Industry: Besides milk, other liquid dairy products are also pasteurized, including yogurt drinks, cream, and liquid cheese. Fruit juices, including orange juice and apple juice, are also pasteurized to eliminate harmful bacteria. Soft drinks manufacturers use pasteurization processes to preserve carbonated soft drinks. Wines and distilled beverage manufacturers also use pasteurization to improve the shelf life of their products.
