The milk factory is the source of milk, and safety and sanitation are the core of food. The high nutrition of milk is also a paradise for microbial activities, and the sterilization of dairy products is a very important link. The processing procedures of dairy products mainly include: raw milk inspection, clean milk, refrigeration, preheating, homogeneous sterilization (or sterilization), cooling, aseptic filling (or sterilization), fermentation, finished product storage, etc., among which fermentation Processes such as disinfection and drying require steam, among which fermentation, disinfection and sterilization in dairy products require the most high-temperature steam, and pure and hygienic food-grade pure steam equipment is an essential equipment for dairy products.
Dairy product fermentation refers to the fermentation of raw milk by lactic acid bacteria or co-fermentation of lactic acid bacteria and yeast in a relatively constant temperature environment under the action of specific microorganisms to make acidic dairy products.
Dairy product sterilization method: pasteurize at low temperature for a long time, keep the milk at about 60°C for 30 minutes; pasteurize at high temperature and short time, keep the milk at 72~75°C for 15~20S; Ultra-high temperature sterilization (UHT), keep the milk at 135-140°C for 3-6S; post-package sterilization, keep the packaged milk at 115-120°C for 20-30 minutes.
The specific operation of pure steam in the sterilization of dairy products, such as ultra-high temperature sterilization (UHT), mixes preheated milk with steam, heats it to 135°C instantly, keeps it warm for a few seconds, and then flashes to cool down quickly and take out the milk. Combined steam condenses water. In this way, the dairy products can be sterilized at room temperature and stored for a long time, while avoiding affecting the taste of the milk, and ensuring that the milk is not affected by factors such as furnace water, iron slag, water treatment chemicals, and odors. Carried by industrial steam. Influence. Nobles steam generators comply with FDA and EN285 requirements for pure steam. At the same time, intelligent frequency conversion control can realize instant steam supply and on-demand steam supply, avoiding waste of steam energy in enterprises.
At the same time, the automatic production line and intelligent monitoring of the steam generator in the workshop of the dairy factory ensure that the steam pressure remains constant and the pressure setting standard is eliminated, manual supervision is eliminated, and the production capacity of the production line is improved.
