Leafy vegetable/Celery /Asparagus/Spring onions/Mushrooms/Flowers vacuum cooling system with CE

Vacuum Cooler Brief Description

The technology is based on the phenomenon that as the vapour pressure on a liquid reduces, its boiling point reduces. The boiling point of a liquid is defined as the temperature at which the vapour pressure of the liquid is equal to the external pressure. When the pressure above a liquid is reduced, the vapour pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases. By reducing pressure we can even boil off water at lower temperatures. This rapid evaporation of moisture from the surface and within the products due to the low surrounding pressure, absorbs the necessary latent healt for phase change from the product itself. This latent heat required for evaporation is obtained mostly from the sensible heat of the product and as a consequence of this evaporation the temperature of the product falls and the product can be cooled down to its desired storage temperature.

This cooling technology not only strongly improves the product quality, but also increases the shelf life of product and at the same time it reduces the cooling costs compared to the conventional cooling method available.

Vacuum Cooler Main Components

a. Control system---To control and show the working condition of the vacuum cooler.

b. Vacuum system--To takes away the air in vacuum chamber, then cool the vegetables down.

c. Vacuum chamber--To load your vegetables

d. Refrigeration system--To catch the water vapor in ths chamber so as to ensure the continous cooling process.

Vacuum Cooler Application Field

Vacuum cooling of Fruit & Vegetables
For leafy vegetables like (iceberg) lettuce, spinach etc are very suitable to be vacuum cooled. The process also works perfectly for field-packed leafy produce, as long as (micro) perforated film is being used.

For "solid" vegetables ranging from (Chinese) cabbage and broccoli to carrots the cooling down process might take (considerable) more time, but the result in shelf life increase can be more than substantial.

For fruits (like strawberries) and mushrooms, it is most important that the produce is cooled down very shortly after harvesting. Also here, vacuum cooling has great advantages in comparison to conventional cooling.
