Vacuum Cooling Technology Brief Introduction:
Vacuum cooling is a rapid evaporation cooling technology.It reduces the chamber's pressure through vacuum pumping so that the boiling point of the water in the products is lowered to have the water vaporized to absorb the products themsevles' heat,then to lower the products' temperature rapidly.
Allcold vacuum coolers now are widely used in the cooling of cooked food industry such as the cooling of pork,poultry,rice,and bean made products,vegetable,bread,cake etc.We have 2 series of vacuum coolers to meet different requirements.Normal temperature series to cool food to around 25-30 degree celsius, the low temperature series to the final temperature could be lower than 10 degree celsius.
Allcold Vacuum Cooler Advantages:
Minimized production losses
Weather variability during the harvest season can cause produce to mature earlier or later than planned.If the produces is not harversted at the potimum 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.
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.
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.
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 production utilization.
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.
