How A Freeze Dryer Works?

1. Freeze-dried function steps include: loading, pre-freeze (complete in quick frozen library), evacuation, sublimation drying, desorption drying, pre-deflated, tamponade and finally deflated and unloading, etc process steps.

2. Main structure: the front box, cold trap (generally together with the box body, can also be used separately), refrigeration system, HTM circulation system, vacuum system, control system, etc.

Shelf area (㎡)	40~250㎡	Shelf spacing (mm)	70~100mm
Water catcher lowest temperature	-50℃	Shelf max. temp.	120℃
Shelf temperature uniformity	≤±1.5℃	Evacuation speed rate	Ordinary pressure~133pa≤15min
Vacuum chamber working pressure	133Pa~26Pa	Ultimate vacuum	≤6Pa
System vacuum leakage rate		≤10Pa.L/s

Main technical parameters of 1000kg fruit & vegetable vacuum freeze drying machine:

1. Vacuumize about 60 cubic. Vacuumize to 133pa need about 25min, front and back in chamber the highest vacuum degree is 6Pa ( during drying process when un-load ).

2. Defrosting use 60 ℃ hot water spraying drenching water flooded. Defrosting time ≤ 30min, defrosting water consumption is about 15T/time.

3. Production capacity and energy consumption (Water and electric) - FN100m2 vacuum freeze dryer per day water separation capability is 1500kg, Dried production moisture content ≤3%.

4. Production limit water content is ≤3%, rate of finished dried products ≥97%.
