Vacuum Cooling Equipment Brief Description

Vacuum cooling equipment is based on the rapid evaporation of water from produce under low-pressure situations. During the process energy in the form of heat is required to change water from a liquid to a vapor; So vacuum cooling equipment can fast cooling down the temperature of produce within 30 minutes.

Because of simple principle and fast cooling speed, vacuum cooling equipment is widely used in preservation, transportation and storage of the agricultural products.

Vacuum Cooling Equipment Main Components

The size of the chamber is defined by the amount of pallets you want to cool at the same time, and their individual dimensions. The size of the chamber will decide the number of vacuum pumps to be used. For the vacuum we are using pumps of the market leaders Busch and Elmo Rietchle. These pumps hardly need maintenance, are reliable and make very little noise.

The evaporator (water catcher) inside the vacuum chamber condenses the water vapour, and ensures only dry air leaves the vacuum chamber towards the pumps.
Outside the chamber, the cold medium (R 404a) is cooled down by a refrigeration system. The compressor needed for this heat exchange process is supplied by (Germany) or by Hanbell (Taiwan).

Vacuum Cooling Equipment Features

1. Cool the products to 0-5 degrees in 30 minutes

2. Uniform cooling style.(the core and the surface reach exactly the same temperature)

3. Very low water loss rate of 1.5-3%.

4. Cure the surface demage of the vegetables and stop their worsening.

5. Energe cost saving because of high efficiency.

6. Never frozen delicate vegetables.
