Milk getting into glycol on chill press
Hello everyone I'm new to this forum. I work at a Milk plant here in the US. I have a question here if any can help. Through the press our milk pressure is 46psi. Glycol is unkown I'm told it fluxuates depending on load.
My (in house engineer) told me that glycol & milk pressure dont have to be close. For example: Milk 46psi Glycol 10psi. Would work perfectly fine w/no leaks.
I just got done visiting w/a refrigeration engineer. He informed me that they should be within 2psi of each other. With the product always being higher than the glycol. This we do but not within 2psi of each other. Now will having glycol at 20psi & milk at 46psi cause the Plate press to leak milk into glycol?
Thanks guys
