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, traditional Chinese medicine 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 a single unit. It features a novel box structure that maximizes the internal space for freeze-drying materials, ensuring that the dried powder exhibits good dispersibility. Throughout the drying process, no impurities are introduced into the material, thereby preserving the original components and active ingredients, as well as the material's shape, without causing damage.
