OVERVIEW
Freeze dryers (lyophilizers) operate on the principle of "ice crystal sublimation," integrating three key stages: pre-freezing, vacuuming, and temperature-controlled sublimation. The equipment typically consists of a drying chamber, a cold trap, a heating system, and a vacuum pump. By gently removing moisture in a low-temperature, low-pressure environment without compromising the material's structural integrity, these machines perfectly preserve the sample's physical structure, biological activity, and chemical properties, making them essential equipment in the field of high-end drying technology. It is for a small-capacity freeze-dryer intended for household use, it is enough to handle various materials, such as fruits, meat, vegetables, herbal medicines, and nutritional supplements etc.
FEATURES
1.Preservation of activity and properties: Drying at low temperatures prevents the inactivation of heat-sensitive substances and maintains the material's original volume and structure.
2.Protection of oxidation-prone components: The vacuum environment minimizes oxygen exposure, effectively protecting substances susceptible to oxidation.
3.Retention of volatile components: Low-temperature processing results in minimal loss of volatile constituents.
4.Inhibition of microorganisms and enzymes: Low temperatures suppress microbial growth and enzymatic activity, better preserving the material's original characteristics.
5.Porous structure and rapid rehydration: The dried product features a sponge-like, porous structure, allowing it to quickly and almost completely return to its original state upon adding water.
6.Prevention of surface hardening: Uniform ice crystal distribution prevents surface hardening caused by the precipitation of inorganic salts.
7.Thorough dehydration for long-term storage: Removes moisture, enabling long-term storage without product deterioration.
8.Low heat source requirements and cost-efficiency: Since the material remains in a frozen state, high-temperature heat sources are unnecessary, making thermal energy utilization more economical.
9. Benchtop mini freeze dryer with dimension 375x700x600mm , including built-in vacuum pump, which occupies less space, it is an ideal choice for home freeze drying machine.
