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 rate at which a product can be refrigerated is directly related to the surface area, density of its tissue and the amount of temperature drop. Typical cooling times range from 20 to 40 minutes at a temperature drop from 80 to 36 degrees Fahrenheit. The average moisture loss is one-percent for each eleven-degree Fahrenheit temperature drop.
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

a. Vacuum chamber-- To load your vegetables. 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.

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

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

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).

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