2014 New Vacuum Pre Cooling Machine

Product Description:
 
Binghai Vacuum Pre-Cooling Machine is a cool processing system, with fast, uniform and clean cooling advantages. The reduction in temperature via vacuum cooler is achieved by rapid evaporation of water when the atmospheric pressure inside the chamber is lowered by a vacuum pump. Generally, it takes only 30 minutes to reach the optimum storage temperature about 0 degrees.
 
Binghai vacuum coolers are excellent in quality and own many models for various uses. Moreover, each machine can be customized to meet your requirements.It can significantly improve the cooling rate, reduce their own consumption of nutrients and keep original texture, color, sensory properties and nutrition of products, which can significantly increase the self life of products as well as reducing the health risk caused by organism growth. So till now, vacuum cooler has been widely used for cooling products in food and catering industry and also in the fresh produce and post harvest sector.
 
Vacuum Cooler Features:

1.Retain freshness and nutrition 
    
2.Prolong preservation time and shelf-life     
 
3.Fast cooling speed and uniform cooling,normal 20 to 35 minutes cooling duration for each cycle     
 
4.Restrain and kill bacteria and animalcule,no pollution     
 
5.Evaporated water ID about 2 to 3% of total goods weight,no localized wilting.         
 
 
Vacuum Cooler Application Fields     
 
Leafy vegetables like (iceberg) lettuce, spinach etc.The process also works perfectly for field-packed produce, as long as (micro) perforated film is being used.For more "solid" vegetables ranging from (Chinese) cabbage and broccoli to carrots, the cooling down process might take (considerable) more time, but the result in shelf life increase can be more than substantial.     
 
For fruits (like strawberries) and mushrooms, it is most important that the produce is cooled down very shortly after harvesting.Fresh cut flowers are a different field of application.Special systems adapted to processing aircraft containers have been made successfully in the past.


  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. The (2-stage) Chinese DLT pumps excel in their sample but effective construction, and are very efficient in usage.
The evaporator (water catcher, special 'ColdMax ' technology, patent pending!) 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 (Tainwan).
 
Three types of condenser systems can be chosen for cooling down the cold medium:
Air condenser: The simplest construction, suitable for small system. Easy to integrate.
Water condenser: Low cost, efficient and easy to install. Perfect for most of climates.
Evaporative condenser: Optimal system for dry climates, or if water availability is limited.
 
 
Standard Models & Basic Specs
 
Our standard range consists of models for 1 up to 10 pallets, and produce weight ranging from 250 to 4,000 kg. The number of pallets defines the chamber dimensions, and the number of vacuum pumps needed to create the vacuum. The following is our general products, we can also customize the vacuum machine as per customers' requirement.
