Vacuum Cooling Technology Brief Introduction:

In a standard atmospheric pressure, the boiling point of water is 100 ºC and the heat of vaporization is 2256KJ / kg. But when the pressure dropped to 610 Pa, the boiling point of water is 0 ºC, the heat of vaporization is 2500KJ / kg. With the decline of air pressure, the boiling point of water decreases, and the heat of evaporating unit mass water consumed increases. Vacuum cooling technology is to put the agricultural products into vacuum chamber, and then extract air in the vacuum chamber by vacuum pump, when the vacuum degree of chamber reaches the saturated pressure of water vapor corresponding to the temperature of agricultural products, the water in the surface clearance of agricultural products like vegetables and fruits start to vapor, and the evaporation will bring away heat so as to lower the temperature of agricultural products. Further lower the pressure to reach the needed cooling temperature of agricultural products. Because of simple principle and fast cooling speed, vacuum cooling technology is widely used in preservation, transportation and storage of the cooked food and agricultural products.

ALLCOLD Vacuum Cooler Advantages:
1.Minimized production losses
Weather variability during the harvest season can cause produce to mature earlier or later than planned. If the produce is not harvested at the optimum time, losses will occur. Late harvesting may also occur if market opportunities are not available at the desired time. Pre-cooling and cold storage are valuable tools that better allow produce to be harvested on time and sold when markets become available.

2.Improved economic of cooking operations
The daily cooling may be increased with the assurance that cooked products quality will be preserved. This confidence permits cooking to be done over a longer period, thus spreading out workloads. Daily harvest hours could also be extended because the effect of ambient temperatures on the produce would be lessened. This flexibility results in better use of equipment and personnel.

3.Minimized losses during marketing
Some types of produce spoil very quickly if not pre-cooled immediately after harvest. These types have to be sold within a day or two of harvesting to be of acceptable quality. Strawberries are a good example. Other examples are leafy vegetables that require trimming to maintain a fresh appearance. Pre-cooling extends the shelf life and thus the opportunity for sale before the produce is no longer marketable.

4.Improved utilization by consumer
Consumers can be supplied with top quality produce with a longer shelf life through pre-cooling. This extended shelf life lessens the urgency to consume or process produce quickly after it is purchased. Consumers are more likely to make larger purchases, enjoy lower handling costs and have more timely product utilization.

5.Expanded market opportunities
Retail marketers require produce of the highest quality that has longest practical shelf life. A highly perishable product that is not pre-cooled, kept cold and handled with care will lose quality and have difficulty competing with a quality imported product. It is also difficult for the lower quality product to meet grading standards. Pre-cooling is, therefore, the key for perishable produce to enter and compete in retail markets.
