Advantages Of Fruits And Vegetables Vacuum Freeze Drying Machine

  • Retain nutrients. Since it is dried under low temperature and vacuum conditions, nutrients are hardly damaged, especially heat-sensitive substances are more prominent.
  • The shape is basically unchanged. Because it directly converts water from solid state to gaseous state, the skeleton of the material remains unchanged after the sublimation and dehydration of ice crystals, and the food skeleton remains unchanged.
  • The original color is easy to maintain. When dehydrated at low temperature, the physical and chemical properties of food change little. Not only the heat-sensitive components are not damaged, but the loss of pigments and fragrances is minimal.
  • The fragrance is basically unchanged. Because the fragrant ingredients in the food remain in the amorphous concentrated part in a large amount during the freezing process, when the ice crystals vaporize, the loss of pigments and aromatic substances is very small.
  • Excellent rehydration, easy to eat. Since the water leaves a lot of pores after drying, the rehydration is good, reaching more than 95%, and the rehydration speed can be completed in a few seconds to tens of seconds.
  • Long shelf life and convenient transportation. Due to the high dehydration rate, no preservatives are required, and it has an extremely long shelf life at room temperature. The product is light in weight, does not require a cold chain for storage, is convenient for storage and transportation, and saves costs.
