The milk processed by uht production line can be stored for a long time without deterioration, and the milk quality is stable without refrigeration. It can be used with aseptic filling machine.
Production line introduction:
1. After the raw milk is accepted, the pretreatment including milk cleaning, cooling and storage should be carried out. After
Filtration and centrifugation, the purified milk should be quickly cooled to 2-3 ℃ for storage. The purpose is to make the quality of the product meet the standard requirements and not fluctuate with the source of raw materials.
2. The purpose of uht milk homogenization is to use the powerful mechanical operation of homogenizer to break fat globules into fine particles, prevent fat agglomeration and floating, ensure the uniform, delicate and white sensory quality of products, and further improve the digestion and absorption of milk.
3. The purpose of uht is to kill all microorganisms (including propagules, pathogens, non pathogens and spores).Generally, the sterilization time is 4-10 seconds and the sterilization temperature is 135-140 ℃. In the first stage, the milk was preheated to 80 ~ 85 ℃, which was helpful to the thermal stability of whey protein. The second stage is to heat the milk above the boiling point to 135 ~ 150 ℃ and completely kill all microorganisms. Raw materials: Fresh milk, milk powder production: Uht whole milk, uht skim milk, uht flavor milk capacity: 500-10000l / h final product packaging: Aseptic brick carton, pillow type packaging bag, plastic bottle
