Vacuum freeze drying technology is the most advanced technology for food dehydration processing at present. Compared with common drying method, Freeze dried food features long period of quality assurance, good rehydration natrue, good-looking color, good flavor, taste, shape and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, it looks like sponge and has no shrinking. This kind drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage and etc.


Natural diets for dogs or cats


  • Especially natural diets for dogs and cats are more important, diets quality should be guranteed by freeze drying processing.
  • Natural nutritional diets are made with 90% meat, bone, blood, tripe, liver, kidney and heart plus 5% egg and green lipped mussel. All meat is sourced from animals deemed fit for human consumption.
  • Natural is an all-you-need to feed diet which can be fed to dogs and cats at any stage of life.

All kinds of freeze dried pet food come from "Shenyang Aero Space Xinyang freeze dryer" producing, let's know about this special machine and processing together.

1. Efficiency of Heating plates

The material of heating plates are  aviation aluminum with anodized on the surface, over 100% heat release to the product by radiation way, keep good heating uniformity everywhere.

2. Alternate Vapor trap

Double vapor trap located under the heating plates inside drying chamber, Just trap 1 condensates water vapor until it can't catch vapor any more, then trap 2 starts condensation function, and trap 1 will begin to be defrost ice for another condensation cycle.

3. Continous De-icing

When the trap 2 begins to catch water vapor, the trap 1 begins to be defrost ice on the tube bundle during product drying, after de-icing,  the empty and smooth tubes for another condensation cycle.

4. Automatic control system

Advanced intelligent control system keeps whole system stable and reliable running for a long term, furthermore, Simple operation method can be much easier to master.
