The main principle of the freeze dryer is a low-temperature drying equipment that uses sublimation to dehydrate materials, freezes water-containing materials into solids, and uses the sublimation performance of water under low temperature and low pressure conditions to dehydrate materials at low temperature and achieve drying. Desktop freeze dryer series is divided into ordinary type, manual gland type, multi-manifold type, gland multi-manifold type and other four models, the main principle of the use of sublimation to dehydrate the material of a low-temperature drying equipment, the water-containing material is frozen into a solid, in the low temperature and low pressure conditions of the use of water sublimation performance, so that the material low temperature dehydration and dry new drying means, suitable for biological research, medicine, chemical industry, food processing, colleges and universities and other fields for freeze drying, bacteria preservation and other fields.
