Heat treatment of milk is one of the most commonly used processing methods to extend the shelf life of dairy products. Most dairy production processes are inseparable from heat treatment. Heat exchange equipment is the core processing equipment in the milk production line. The purpose of heat treatment of milk is two, one is sterilization (tuberculosis bacillus) to ensure food safety; the other is to raise the temperature of milk to a temperature that can be processed later, it is milk The starting point of the production line is also the core technology.
Plate heat exchangers can be divided into one-stage, three-stage, four-stage and five-stage plate heat exchangers according to structure. Milk production line equipment; three-stage plate heat exchangers include cooling section, heat return section, and heating section; four-stage plate heat exchanger is the structural method often mentioned in our milk production line, which can effectively improve product quality; The structural composition of the segment plate heat exchanger is the ice water cooling section, the cooling water cooling section, the heat recovery section 1, the heat recovery section 2, and the heating section.
Some dairy factories stipulate that cold milk should be centrifugally purified immediately after entering the dairy factory. If the milk is to be stored for use the next day, it should be treated like this. For the milk production line, it is more effective to purify milk at 55 degrees. The milk entering the milk purifier is milk from the first heat recovery section. For the pasteurization process of the milk production line, the quality of the milk produced by the plate heat exchanger is better than the tank sterilization method. For units with large output and high quality requirements, the plate sterilization method is first recommended.
The milk production line uses hot water to heat the product to reach the pasteurization temperature, and then cools through the heat recovery section. The cooling temperature of the heat recovery can reach 8 degrees. If a lower temperature is required, it can be used with ice water. Plate heat exchangers not only have high thermal efficiency, fast production process, but also produce products with much higher homogeneity, energy saving and electricity saving. For customers who use milk production lines for a long time, the last set of plate heat exchangers should shrink the enterprise. The cost of production is undoubtedly a better way of running the enterprise's scientific development.
