Several common cooling conditions for precooling of cold storage.

Pure temperature cooling

Applied for some required temperature such as for frozen fruit and vegetable, various food, liquid etc… this kind of precooling is merely temperature decreasing, its physical form remains unchanged, only the heat loss.

Solidification cooling

The kind of precooling mainly is used for oil and grease commodities. Such as the animal oil, vegetable oil, margarine, chocolate etc.. in which case the liquids turn out to be solid.

Eduction cooling

This kind of precooling is mainly used for juice, brine, oil, acetone, paraffin etc..

In order to prolong the shelf life of fruits and vegetables and decrease the loss during transport the precooling is an indispensable process. Only by precooling can make cold storage more useful. Fruit and vegetable remain high temperature when newly harvested and will incur moisture loss and nutrients loss. Precooling prevent above problems.
