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 Bitzer (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
5. Energe cost saving because of high efficiency.
6. Never frozen delicate vegetables.
