The main components of a vacuum cooler (1/2)

1. Vacuum cooling chamber

The size of the vacuum cooling chamber must be large enough to maintain the batch and work gaps for each cycle and to allow for possible future changes in stacking serious pallets or stack sizes. We offer customized vacuum chambers that are suitable for single or double rail transport systems. The chamber door can be a sliding or lifting vertically type.

2. Vacuum pump

This is used for the first evacuation of the vessel, from atmospheric pressure to the flash point of the water. After reaching the flash point, the efficiency of the pump is limited by the cooling unit. In general, we adjust the size of the vacuum pump to 5-8 minutes to reach the flash point. The type of pump that is commonly used is Single stage oil seal rotary vane pump.

3. Refrigeration equipment

As soon as the pressure reaches the flash point, the water begins to evaporate from the surface of the product. It is this evaporation that achieves cooling. For instance, in a machine that cools 1000 kg of product per cycle, 1860 m3 of steam is produced and pumped out of the chamber which is too large for vacuum pump to handle, so a freezing unit is installed in the room to condense the steam to the water again - the cooling unit is actually like a vacuum pump.
