Vacuum Cooling Equipment Brief Description

The vaccum cooling process starts with the palletized product being loaded into the vacuum cooler either by forklift or automated pallet loading systems. Once loaded, the vacuum cooling systems starts to evacuate the air from the vacuum chamber. The reduction in temperature via vacuum cooling is achieved by rapid evaporation of water when the atmospheric pressure inside the chamber is lowered to the desire level by the vacuum pump.

The more surface area that the product has, compared to its weight, the greater the amount of heat that can be dissipated at a rapid rate. This means that vacuum cooling is an excellent way to cool products such as leafy vegetables and mushrooms. After some of the moisture in the product is pulled from the product and changed into vapour, the refrigeration coils pull the heat laden vapour away from the product and re-condenses it.

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 Bitzer (Germany) or by Hanbell (Taiwan).
