Equipment Overview: A vacuum freeze dryer is a device that utilizes vacuum and freezing technologies to achieve the freezing and sublimation of substances. It is widely applied in laboratories, pharmaceuticals, food industries, and other fields. It is suitable for drying high-end raw materials for medicines, Chinese herbal decoction pieces, seafood, wild vegetables, dehydrated vegetables, food, fruits, chemical drug intermediates, and other materials. The vacuum freeze dryer integrates the refrigeration system, vacuum system, heat transfer oil heating system, and dehumidification system into one. It features a novel box structure that maximizes the internal space for freeze-drying materials, ensuring good dispersibility of the dried powder. During the drying process, no impurities are introduced into the material, preserving its original components and active ingredients, as well as its shape without damage.
