JKI New type of freeze-dryer including: Control apparatus and Refrigerating apparatus that being placed in refrigeration storage and Vacuum drying equipment. The refrigeration equipment and vacuum drying equipment work synchronously , keep the former equipment’s temperature at a low basis and put material into refrigeration equipment for pre-freezing , and then put it into vacuum drying equipment for dehydration.

The shell of the vacuum drying equipment is provided with heating pipes, which used for defrosting during the freeze-drying process.

The vacuum drying equipment consists of at least one vacuum box body.The vacuum tank is provided with plexiglass door, with tubes on the top and side of the tank, with adjustment feet on the bottom. All tubes are channel steel.

The refrigeration equipment consisting of at least one shelf carts. The top of the shelf carts is made of stainless steel tray configuration, provided with stainless steel tubes on the four sides and directional wheel on the bottom.

The process of operation as following:

Use the refrigeration equipment to keep the refrigeration chamberin low temperature , normally , keep it atm-40C.

Put the original material like fruit or vegetable which need to vacuum fryer on the goods shelf carts and put it into the refrigeration chamber for pre-freezing. When the original material temperature below -40C , put it into the vacuum tank for vacuum dryer
