I.Product General DescriptionVacuum cooler is a machine that provide pre-cooling way of vegetable and fruit , cooked food etc .The principle of vacuum cooler is by reducing atmospheric pressure in artificial hermetically sealed chambers. Reducing the atmosphere pressure also reduces the water vapour in the chamber , then the water start to evaporate rapidly, and bring away the heat from vegetable ,fruit and ready food along with evaporation.Vacuum cooling is the quickest and most cost-efficient cooling system for vegetables, fruits, flowers and more. The vacuum cooling technology can prolong your postharvest products shelf time ,reducing rotting rate , and strongly improve your product quality ,Now is becoming an acceptable investment for almost all vegetable growers!
II.Three different types of doors can be used:Standard Swing Door:Most simple construction, Manual operation, The ramp for this system is relative long and is mounted inside the cooling chamber.Horizontal Sliding Door:This electrical driven door is optimal if the cooling skid is placed besides the vacuum chamber(one pallet model and >6 pallet systems )Upward Lift Door: Hydraulic system, suggested solution for all systems from 2-6 pallets, Easy installation,easy ramp construction.It is also possible to use two doors in combination with a roller belt system,for maximum efficiency of the loading process limited.
III.Main ComponentsThe size of chamber is defined by the amount of pallets you want to cool at the same time, and their individualdimensions, the sie of the chamber will decide the number of vacuum pumps to be used ,Vacuumpump:Dalouton(China),Tongxin(Domestic),Leybold(Germany),Busch(Germany)The evaporator(water catcher,WanJia special R&D technology),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(R104A) is cooled down by a refrigeration system ,the compressor needed for this heat exchange process issupplied by Bitzer(France) or by Hanbell (China Taiwan)
IV.Three types of condenser systems can be chosen for cooling down the cold mediumAir condenser:the simplest construction,suitable for small system,Easy to integrateWater condenser:Low cost ,efficient and easy to install ,perfect for most districts climates.Evaporation condenser:Optimal system for dry climates ,or if water availability is limited
V.Control System:The specific develop control system ensures that the cooling process works pefect, even with partial loading , the target temperature will be realized quickly , without freezing of the delicate vegetables, the processing data are collected in the system, and all relevant processing parameters can be seen on the display.The electronics used are from LS(LG group),Control valves&components come from leading suppliers like Danfoss and Leybold. The system can be started with on push the button, the touch screen display is very easy to operate and user friendly,the menu will be supplied in the local language.
