The SFD series vacuum freezing and drying technology is currently the most advanced dehydrating process technology in the world.
Compared with the commonly used drying method,the freeze dried food produced with this technology features long period of quality assurance,good re-hydration nature,goo-looking color,good flavor,taste and high content of nutritious components
The dried food basically remains unchanged in its volume and shape,looks like sponge and has no shrinking...
The SFD series vacuum freezing and drying machine can be widely used in such fields as vegetables,fruits,condiments,
seafood,biological products,medicine,beverage,specimen etc.Main technical parameters of SFD vacuum freeze drying equipment
|Model||Drying area|| Capacity||Drying temp||Drying time||Power||Dimension(LxWxH)|
1) Qucik freezer room is made of PU color steel plate.
2) First freeze the product into -18ºC after 3-4 hours.The room temperature can be -18ºC~-35ºC.
3) Inner with copper tube aluminum sheet and cooling fans
1) The horizontal cylindrical pot is made of stainless steel 304.Name: cold trap
2) Heating plates are installed in both sides.Surface anodicoxidation treatment for the aluminum plate.Releasing over 100% heat from the product by radiation.This makes heat more uniform and complete.
3) Heating temperature can be normal to 120ºC.
1) It is made of stainless steel 304.
2) Cold trap can catch water from the material.While moisture in the product is sublimating under vacuum enviroment,cold trap catch the water and melt ice on the coil after drying.Then is ready for another condensation cycle.
1) World famous brand of vacuum pump,German Leybold.Our Customers:
2) Two units of vacuum pump,roots+rotary-vane pumps.
When pre-vacuumized,need two units open together to make sure the pot reaching 133Pa within 15 minutes quickly.Product won't change shape or anything.
When formal vacuum drying, one unit of pump to ensure vacuum environment is ok.Energy save.
