The freeze dryer produced by our company will be carefully packed before delivery to ensure the integrity of equipment accessories, friends outside to carry the case, prevent collision phenomenon in the transportation process.

Since vacuum freeze-drying techology is carried out in low temperature and low oxygen environment, most biological reactions are stagnated, and there is no liquid water in the treatment process, the water is sublimated directly in solid state, so that the original structure and shape of the material can be protected to the maximum extent, and finally a high-quality dry product with both appearance and internal quality can be obtained.Due to the difference in the amount and nature of the substances to be freeze-dried, not only a large number of equipment need to be put into use, but also an unusually wide variety of these equipment.

The freeze dryer is composed of refrigeration system, vacuum system, heating system and electric instrument control system.The main components are drying box, condenser, refrigerating unit, vacuum pump, heating/cooling unit, etc.It works by freezing a dry item below the triple point temperature and then sublimating the solid water (ice) directly from the dry item to water vapor under a vacuum condition, removing it and drying the item.After pre-treatment, the materials are sent to the quick-freeze warehouse for freezing, then sent to the drying warehouse for sublimation and dehydration, and then packaged in the post-treatment workshop.
