The vacuum freeze dryer is divided from the function

Ordinary shelf type: The material is bulk packed in the material tray, which is suitable for freeze-drying of food, Chinese herbal medicine and powder materials.

Type with capping device: suitable for drying vial bottled materials. When preparing for freeze-drying, divide the material into vials as needed, float the caps and then freeze-dry them. After drying, operate the capping mechanism to compress the caps. , which can avoid secondary pollution, re-adsorb moisture, and be easy to store for a long time.

Multi-manifold type: a flask is installed outside the drying chamber to dry the material spun on the inner wall of the bottle. At this time, the flask is connected to the manifold outside the drying box as a container. The material in the flask is heated at room temperature and passes through the multi-manifold. Tube switch device, the flask can be removed or installed at any time as needed, without downtime.

Type with pre-freezing function: During the material pre-freezing process, the cold trap is used as the pre-freezing chamber to pre-freeze the material. During the drying process, the cold trap is used as a water trap to capture the water overflowing from the material. The freeze-drying machine with pre-freezing function, the pre-freezing and drying of the materials in the freeze-drying process are completed on the freeze-drying machine, the freeze-drying machine has high efficiency and saves the cost of low-temperature refrigerators.
