Product Main

Specifications

Working Principle:

The product is placed in a vacuum so that the atmospheric pressure around the product is reduced. This reduces the water vapor pressure around the product, and when the pressure is lowered below that inside of the product, water evaporates from the product.  This in turn lowers the surface temperature of the product.

 
Product Features:
a. Retain freshness and taste, extend shelf time for vegetable, fruits, flowers etc.
b. Cools large volumes and weights of produce rapidly;
c. Uniform temperature easily obtained;
d. Optional moisture enhancement systems can reduce weight loss;
e. Sanitizing agents can be incorporated in moisture enhancement systems;
f. High volume users can achieve low unit costs with correctly matched equipment.
 
Structure of vacuum cooling system
Vacuum cooing system or vacuum cooler is composed of four main parts.
a. Vacuum chamber

Vacuum chamber is the spaces for fitting pallets of produce and track conveyor system. According to practical application, the space could be manufactured from 1 pallet to 16 pallets or more. Vacuum chamber should sustain the big pressure from outside when decompressed, so it is normally made of steel to ensure enough intension.

b. Vacuum system

Vacuum system take away air from vacuum chamber at desired speed (m3/s) according to actual application. In the vacuum system, vacuum pumps are the main parts. Vacuum pump will affect the water evaporation speed inside chamber. Before vapor in chamber saturated, faster water evaporated, faster produce temperature reduce.

c. Refrigeration system

Refrigeration system is composed of compressor, expansion, dry filter, liquid receiver, oil separator, gas separator, pipes, etc. Refrigeration system will condense vapor to liquid water to ensure vapor in chamber will not saturate. If vapor saturated in chamber, the water on produce will not evaporate any more. That means, no water evaporation, no temperature reduce.

d. Control system

All above three systems works well coordinated by control system including temperature control, pressure control, high-low pressure control, compressor control, loading control, remote control, etc. Control system is the central part of whole machine which is always special made according to different applications.
