A plate pasteurizer with three sections is a type of food processing equipment used to heat and cool liquids, such as milk, juice, or soup, to kill harmful bacteria and extend the shelf life of the product.
The three sections of the plate pasteurizer typically consist of a preheating section, a heating section, and a cooling section. In the preheating section, the liquid is slowly heated to a set temperature to remove any initial cold spots and prepare it for the pasteurization process.
Next, the liquid enters the heating section, where it is rapidly heated to a specific temperature, usually around 71-74 degrees Celsius (160-165 degrees Fahrenheit), and held at that temperature for a predetermined amount of time, commonly 15-30 seconds. This high temperature kills bacteria, yeasts, and molds that may be present in the liquid, ensuring its safety for consumption.
After the heating section, the liquid moves into the cooling section, where it is rapidly cooled down to a lower temperature to prevent further bacterial growth. The specific cooling temperature and time depend on the type of liquid being processed.
Plate pasteurizers are designed with a series of plates stacked together, with alternating channels for the liquid and for hot/cold water to flow through. This design allows for efficient heat transfer between the liquid and the water, enabling rapid heating and cooling.
The plate pasteurizer with three sections is typically used in small to medium-scale food processing operations, such as dairy farms, juice producers, or soup manufacturers. It offers a cost-effective and energy-efficient method for pasteurizing liquids, ensuring product safety while maintaining the desired taste and quality.
Application：
The fully automatic flat plate pasteurization machine has demonstrated its important value in multiple industries. Here are several specific application cases:
In the dairy industry, these equipment are used to process milk and other dairy products. They are briefly heated at a temperature of 72 ° C to 75 ° C (for 15-20 seconds) to effectively kill bacteria while preserving nutrition and flavor. They are suitable for producing pasteurized milk, yogurt, cheese, etc.
This technology is widely used in the beverage manufacturing industry for sterilization of non-alcoholic beverages, such as carbonated drinks, tea drinks, and fruit juices.
Juice processing is particularly beneficial as it can be processed for a short period of time at 85 ° C to 90 ° C, maintaining the color, aroma, taste, and nutrition of the juice, ensuring safety, and extending shelf life. For juice processing of beverages containing fruit grains, the fully automatic flat plate pasteurizer can adjust parameters to protect the integrity of the fruit pulp while completing effective sterilization. Its automated cleaning function (CIP) maintains high hygiene standards for the production line.
These examples demonstrate how fully automatic flat plate pasteurizers can support the high standard production needs of the food and beverage industry with efficient and precise operation.
