Plate Heat Exchanger-Sanitary Application

Item No.: 002

Plate Heat Exchanger for Diary Application

 The Plate Heat Exchanger (Multi-Section) is Widely used in Dairy plant for Pasteurization and Cooling process.During milk Ultra High Temperature Pasteurization, the low temperature milk passed into Heat Recovery Section Plate Heat Exchanger through Balance Tank1 and Material Pump2, the milk will be pre-heated there. After pre-heating, the milk will enter into homogenizer for homogenizing. After that, it will enter into Heating Section of Plate Heat Exchanger, and be heat into 137℃. The milk will be insulated 4 second at 137 ℃ for UHT. After UHT, the milk will enter into Cooling Section of Plate Heat Exchanger. After Cooling, the milk can be packaged.

Plate heat exchangers are widely used in the food industry due to their efficient heat transfer capabilities and hygienic design. In particular, they find extensive application in the dairy industry, specifically in the process of pasteurizing milk through the method of high-temperature, short-time (HTST) treatment.

Milk Pasteurization Process:
Milk pasteurization is a critical step in dairy processing to ensure the destruction of harmful bacteria while maintaining the nutritional quality of the product. The HTST method involves rapidly heating the milk to a high temperature (usually above 72°C) for a short period (15-20 seconds) and then rapidly cooling it to below 6°C. Plate heat exchangers play a pivotal role in this process.Working Principle of Plate Heat Exchangers in Milk Pasteurization:Plate heat exchangers operate on the principle of indirect heating, where the milk and the heating medium (often hot water or steam) flow on opposite sides of the plates. The heat is transferred through the plates, resulting in temperature rise or reduction, depending on the specific stage of the pasteurization process.

The application of sanitary grade plate heat exchangers in the food industry, with a focus on their significance in the milk pasteurization process.

Hygienic Design of Plate Heat Exchangers:
Hygiene is of utmost importance in the food industry, especially in dairy processing. Plate heat exchangers designed for food applications conform to stringent hygiene standards, ensuring the safety and quality of food products. Features of Shineheat hygienic design Plate Heat Exchanger include:
a) Smooth surfaces: The plates in these heat exchangers have smooth, non-porous surfaces that prevent the accumulation of food residues and microorganisms.
b) CIP capability: Plate heat exchangers can be easily cleaned in place (CIP) using sanitizing agents, ensuring efficient removal of contaminants.
c) FDA-compliant materials: Plates are made from FDA-approved materials, such as stainless steel, that are resistant to corrosion and easy to clean.
d) Seal design: Special attention is given to the design of gaskets and seals to prevent any contamination between the product and service fluids.

Sanitary Grade Plate Heat Exchanger

Advantages of Plate Heat Exchangers in Milk Pasteurization:
a) High energy efficiency: Plate heat exchangers enable efficient heat transfer due to their large heat exchange area, resulting in minimal energy wastage.
b) Precise temperature control: The design of plate heat exchangers allows for accurate temperature control, ensuring optimal pasteurization and reducing the risk of product quality issues.
c) Reduced product degradation: The HTST method, facilitated by plate heat exchangers, minimizes the exposure of milk to heat, preventing excessive thermal damage and maintaining its nutritional value.
d) Improved productivity: Plate heat exchangers offer efficient heat transfer rates and self-cleaning capabilities, allowing for uninterrupted operation and increased processing capacity.

Sanitary Grade plate heat exchangers play a vital role in the food industry, particularly in milk pasteurization. Their ability to efficiently transfer heat while maintaining hygienic standards and product integrity makes them the preferred choice for ensuring food safety and quality. The adoption of plate heat exchangers not only benefits the dairy industry but also serves as a foundation for a strong and reliable food supply chain.

Not only in Dairy Industry, Hygienic plate heat exchanger also widely apply for Chemical, Pharmaceuticals and Semiconductor Industies.
The main features of Sanitary Plate Heat Exchanger is that all the components or accessories are made by Stainless Steel or Stainless Steel Coating, it is easier for machinery surface cleanning and sterilization.
