Types of pasteurizations

Continuous Method

Pressure Differential

For continuous pasteurizing, it is important to maintain a higher pressure on the pasteurized side of the heat exchanger.


By keeping the pasteurized milk at least 1 psi higher than raw milk in regenerator, it prevents contamination of pasteurized milk with raw milk in event that a pin-hole leak develops in thin stainless steel plates.

This pressure differential is maintained using a timing pump in simple systems, and differential pressure controllers and back pressure flow regulators at the chilled pasteurization outlet in more complex systems. The position of the timing pump is crucial so that there is suction on the raw regenerator side and pushes milk under pressure through pasteurized regenerator. There are several other factors involved in maintaining the pressure differential:

The balance tank overflow level must be less than the level of lowest milk passage in the regenerator

Properly installed booster pump is all that is permitted between balance tank and raw regenerator

No pump after pasteurized milk outlet to vacuum breaker

There must be greater than a 12 inch vertical rise to the vacuum breaker

The raw regenerator drains freely to balance tank at shut-down

its much better drink pasteurized milk so as to e away from milk born diseases i like and i m at muhimbili university study milk processing.

Haha, I was about to type what ZenZappa wrote and I scrolled down and saw your comment. Yes, this page is mislabeled. Antony [Anton] van Leeuwenhoek IS the Father of Microbiology because he was the first to discover the existence of protozoa and bacteria.

I need to pastries small quantity of camel milk. Where you think I can find small pasteurization equipment for sure High temperature short time type?.
