Apr 09, 2018

Nowadays most food growers, processors, wholesalers, logistics practitioners, have great sense of cold storage, and building a cold storage for goods has been a mainstream. But do you put goods directly into cold storage? 

Haocool hereby tell everyone reading this article that it is wrong. 

So next we see the precooling problem for food and other commodities.

So-called precooling, mainly indicates food and other commodities that will later be put into cold storage shall endure a process of cooling to 0 ℃ or designated cold storage temperature  from atmosphere temperature. 


The purpose of precooling: precooled goods are put into the cold storage then prolong the fresh-keeping time duration and decrease the power consumption.

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.


And of course the precooling is realized through special facilities. Haocool will assist customers to build a conforming cold storage and precooling facility and help all preserve goods in a more decent way.
