2 Pallets Per Cycle Vacuum Coolers R404A / R407C For Fresh Broccoli Precooling​

Vacuum Cooler Brief Description

After the product is harvested and packaged, it is placed on pallets for shipping. The pallets are loaded into a vacuum tight chamber and the process begins. The equipment drops the pressure inside the vessel by removing air through vacuum pumps. Once the level of vacuum reaches the "flash point" moisture and heat are removed from the product in the form of water vapor. The lower the pressure inside the chamber, the lower the boiling point of water. As the vacuum goes deeper, more water vapor is removed and the product temperature is reduced until the desired temperature is achieved.
The water vapor must be removed in order for the process to work efficiently. The vacuum draws the water vapor past refrigeration coils which condenses the vapor back into water. These two systems allow the process to achieve desired product temperature more rapidly than any other post harvest cooling technique.
Since produce is sold by weight, a hydro-vac system can help reduce moisture loss. This works by spraying clean water over the produce during the vacuum cooling cycle.

Vacuum Cooler 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).
