Product category：Vegetable Vacuum Precooler
Vacuum Cooler/Vacuum Cooling Machine
Utilizing vacuum pump for pumping air inside vacuum chamber to reduce its pressure,comined with refrigeration system for vapor condensation to realize fast cooling purpose.At low pressure,water boiling temperature lower,evaporation potential heat increased,free water on product surface evaporation quickly so as to take away itself heat,then environment temperature and cooling performance reached.
Vacuum Cooler is not cold storage equipment,but cooling processing equipment before product put into cold storage rom or shelf.After vacuum cooling,product physiological change slow down,its storage life and shelf life are extended .Vacuum cooler is designed by lower water boiling point temperature at low pressure and high evaporation heat with following features:
lFast cooling speed:15-30mins to desired temperature.
lAverage cooling:Product surface free water evaporation take itself heat to realize cooling purpose from inside to outside,average temperature drop.
lClean and hygiene: able to kill bacterial or restrain bacterial reproduce in vacuum environment, also prevent cross contamination.
lThin layer drying effect: unique effect for curing produce surface hurt and restraining its expansion.
lUnlimitation on packing:Only with small hole on packing,produce average cooling can be realized.
lHigh fresh preservation:can maximum keep product original color,flavor,taste and shelf life.
lHigh automation:control refrigeration system and vacuum system by sensor,conveniently adjust vacuum degree,remote control to monitor equipment running and fast troubleshooting.
lHigh precision:With high precision digital temperature display,mositure controller to control vacuum degree and mositure exactly.
lSafe and stable: adopt brand electric components to guarantee machine running stably, long life time and safe operation.
1. Able to custom the machine according to customer's requirements.
