Pressure covered vacuum freeze dryer

1、 Working principle

Pressure covered vacuum freeze dryerThe drying principle is mainly based on the three state change law of matter. When a substance reaches a certain level at low temperatures, its molecular motion slows down and forms a solid state. In a vacuum environment, the influence of external pressure on water molecules decreases, and the intermolecular distance increases, allowing water molecules to sublime directly from the solid state to the gas state, achieving the purpose of drying. This drying method can preserve the original nutritional content and color of the material, while avoiding the oxidation and deterioration of some heat sensitive substances.

2、 Application scope

Vacuum freeze dryerWidely used in fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treatment are easy to store for a long time, and can be restored to their pre freeze-drying state and maintain their original biochemical characteristics after adding water.

3、 Product Description

BIONOON22BPressure covered vacuum freeze dryerLordTo be used in fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treatment are easy to store for a long time, and can be restored to their pre freeze-drying state and maintain their original biochemical characteristics after adding water.BIONOON-22BVacuum freeze dryer, suitable for freeze-drying bulk (liquid, paste, solid) conventional substances, can be used in conjunction with penicillin bottles. After sample freeze-drying, it can be directly sealed in the drying chamber.
