LTDG-0.2 New Type Vacuum Freeze Drying Machine for fruit and vegetable

Theory of freeze-drying

Vacuum freeze-drying method is a liquid → solid → gaseous process. In freeze-drying process, "liquid bridge" between the solution particles has been frozen into "solid bridge". The relative position of particles has been fixed and does not exist surface tension on gas-liquid interface between the two particles. With the continuous distillation of solvent, "solid bridge" continuously decrease, but the the relative position between two particles will not longer change until the "solid bridge" completely disappear.

The use of freeze-drying technology

   1.The bio-products, medicine aspects: such as the anti-virus medicine, anti-toxin medicine,examination products for patients and vaccine conservancy.

   2.The microbial and algae aspects: such as various bacteria, yeast,enzyme, protozoon, micro-algal etc for the long-term conservancy.

   3.The bio-products specimen, bio-organism aspect: such as manufacturing various plants specimen, the dry conservancy used for the skin, skeleton, aorta, the heart valve transplantation of different or the same race animal

   4.The manufacture used for the optical microscope, electronic scan and watch through the small group of the microscope.

   5.The drying aspect for food: such as the coffee, tea-leaf, meat, fish, egg, seaweed, fruit, vegetable, dressing, bean curd, instant food etc.

   6.The top-class nourishment and herb medicine aspect: such as the queen bee syrup, honey, pollen, and chinese herb medicine products etc.

   7.The making aspect of the micro powder: such as making to micro powder, such as Al2 O3,ZrO2,TiO2,Ba2 Cu3 O7~ 8, and the Ba2 Ti9 O20 etc.
