The production process of pasteurized milk: raw material storage - filtration - sterilization - filtration - homogenization - cooling - low-temperature storage - filling
Supporting equipment: Raw milk tank - Pump - Filter - Pasteurization tank - Pump - Filter - Homogenizer - Pre cooling tank - Pump - Low temperature storage tank - Canned
The customer stores fresh milk as a whole in a fresh milk storage tank, which is cooled by a compressor and has a low-temperature storage function. When sterilization is required,
Turn on the centrifugal milk pump connecting the storage tank and the 8-parallel pasteurization tank, and filter and sterilize through 350 # thermal oil or hot water,
The sterilization time is about 2-2.5 hours, and the sterilization temperature is 85 ° C.

After sterilization, the milk is pumped into a filter for secondary filtration. After filtration, the pasteurized milk is homogenized in a homogenizer.
After homogenization is completed, turn on the centrifugal milk pump and complete yogurt processing equipment, and pour the pasteurized milk into the pre cooling tank. The pre cooling tank uses cold water for cooling, and the cooling time is about 1-1.5 hours,
Usually, it needs to be cooled to below 45 ° C before being sent into the refrigeration tank of the compressor, otherwise it will affect the quality of the milk and the service life of the equipment.
After the cooling is completed, turn on the centrifugal milk pump connecting the pre cooling tank and the refrigeration tank, and pour the pasteurized milk into the refrigeration tank for storage.

equipment introduction
The pasteurization tank is mainly composed of several parts such as the tank body, mixing motor, heating system, and electrical control.
The tank body is entirely made of stainless steel SUS304, which has been precision polished to prevent dirt from accumulating and is easy to clean and corrosion-resistant.
The insulation layer of the tank body is filled with rock wool or polyurethane foam insulation material with low thermal conductivity, which is lightweight and has good insulation performance.
★ Four corner R-angle transition, using fast discharge valve, no dead corners, convenient for quick discharge.
