Commercial Food Freeze Dryers

The Vikumer FDRS freeze dryers are medium capacity food freeze drying equipment. Capable of freeze drying all food items include fruits, vegetables, seafood, meat, soup, meat, dairy, nutrient and health care items. These machines are designed for commercial production, entirely stainless steel 304 fabricated and commercial high performance.

Process of the FDRS is fully automatic. Raw products are placed in drying chamber, in place freezing and later heating for sublimation. All parameters are accuracy controlled and monitored through a user friendly HMI touch screen. Vapors that come out from materials will condense on condenser coils surface, which is chilled by compressor system.

Customers can select either conductive heating or more efficiency radiative heating shelves. Both of them capable of freezing and heating function, by silicone oil circulates inside sandwich type plates.

All the machinery that involved with the operation of FDRS freeze dryer is mounted on a steel frame. Plug and play deliver. Quick install by connect electric, compressor chilled water, compressed air source and condenser defrost water.
