Shanghai Jimei Food Machinery Co. Ltd

Model Number: JML Brand Name: JIMEI Key Specifications/Special Features: Complete turn-key project liquid pasteurized milk processing lineDescription:Processing line produce several types of pasteurized milk products, example whole milk, skimmed milk and standardized milk of various fat contentsFirst milk is preheated and standardized by in line milk fat standardization system, purpose of standardization is to give the milk a defined, guaranteed fat content, common values are 1.5% for low fat milk and 3% for regular grade milk, fat contents as low as 0.1 and 0.5% is skimmilkThen standardized milk is homogenized, purpose of homogenization is to disintegrate or finely distribute the fat globules in the milk in order to reduce creaming,homogenization may be total, partial homogenization is a more economical solution, because a smaller homogenizer can be used

Milk, now is pumped to the heating section of the milk heat exchanger where it is pasteurized, necessary holding time is provided by a separate holding tube, pasteurization temperature is recorded continuously, pump is a booster pump which increases pressure of the product to a level at which the pasteurized product cannot be contaminated by untreated milk or by cooling medium if a leak occur in plate heat exchanger, if the pasteurization temperature should drop, this is sensed by a temperature transmitter, a signal activates flow diversion valve and the milk flows back to the balance tank, after pasteurization the milk continues to a cooling section in the heat exchanger, where it is regenerative cooled by the incoming untreated cold milk, and then to the cooling section where it is cooled with ice water, the cold milk is then pumped to the filling machines, temperature and pasteurization holding time are very important factors which must be specified precisely in relation to the quality of the milk and its shelf life requirements

Pasteurization temperature is usually 72-75C for 15-20 sec

A common requirement is that heat treatment must guarantee the destruction of unwanted microorganisms and of all pathogenic bacteria without the product being damaged
