1. Introduction

The working principle of the vacuum freeze-dryer is to make the water in the pre-frozen drug to in the vacuum state, based on use the sublimation principle, not through the ablation of ice, directly sublimate into water vapor and to be removed, so as to achieve the purpose of drug freeze-drying. The pharmaceutical freeze dryer combines refrigeration system, vacuum system, heat conduction oil heating system and dehumidification system. The freeze dry supplier introduces a new type of box structure, which can be divided into laboratory freeze drying machine, raw material freeze drying machine, pilot production freeze drying machine, industrial freeze drying machine and so on. The freeze-drying products are spongy, dry-shrinking, excellent rehydration, little moisture content, and can be stored and transported at room temperature for a long time after packaging; Widely used in raw materials, Chinese medicine pieces, biological products, vaccines, blood products, active substances, antibiotics, food, fruit, chemical, pharmaceutical intermediates and other materials drying production.
