Vacuum Freeze Dryer Machine for Food SED-DG Series

The vacuum freeze dryer machine is a stable material freeze-drying process. The material with retained moisture or water will be frozen first, then the water content within the material will undergo sublimation and be converted directly from solid to gas which will remove it from the material while preserving the material’s original qualities.

Product Description

Introduction of Vacuum Freeze Dryer Machine

The vacuum freeze-drying principle of this dryer dehydrator is a process by which the liquid in the product is converted into a solid, and then the solid is converted into a gas.

In the process of freeze vacuum drying, the “liquid bridge” between the solution particles has been frozen into a “solid bridge”. The relative position of particles has been fixed and there does not exist surface tension on the gas-liquid interface between the two particles. With the continuous distillation of solvent, the “solid bridge” continuously decreases, but the relative position between two particles will no longer change until the “solid bridge” completely disappear.

Features of Vacuum Freeze Dryer Machine

  • The vacuum freeze dry chamber is made of stainless steel which meets high standards of product processing requirements
  • Lamellar refrigeration ≤-50°C, Trap refrigeration ≤-60°C
  • The screw compressor uses environmental refrigerant R404a, from an international brand
  • Lamellar has a constant temperature in the cooling and sublimation process
  • Vacuum pump with high-performance valve and roots pump has oil-water separating function
  • The cold trap of water replenishes highly, and defrosting is fast
  • Electronic signature with American Electronic record of FDA CFR PART 11
