we produce semi-automatic and fully automatic milk pasteurizer. For semi-automatic machine, we need press the button to control the pump, and open and close some of the valve by manual. For fully automatic milk/jucie pasteurizer, we have touch screen and PLC control. And our heat regeneration degree can be reached to 96%. 1. Other instruments and meters used in this machine Pasteurizer has its on CIP equipment (acid barrel, alkali barrel, acid & alkali diaphragm pump). It has a buffer tank, hot water tank, temperature sensor, pressure gauge, steam propotion adjusting valve, steam pressure reducing valve, tap valve, etc. Our machine pasteurizing temperature can be reached to 65-95 deree celsius. 2. Heating and cooling process explain 2.1. Heating process. Using steam to heat the water (water changed to hot water)-----Using hot water to heat product (We have designed the lquantity of the plate so that the product sterilizing temperature can reach the customer requirements) 2.2. Cooling section Hot water become cooled water when heating the product----- Using cooled water to cool down the product ( hot energy recycle)----using tower water to cool down the product----using iced water to cooling down the product.
