What is a Vacuum Freeze Dryer? How does it work?
Freeze-drying is the process of removing water from frozen materials. Freeze-drying is divided into vacuum freeze-drying and atmospheric freeze-drying. Due to some constraints, vacuum freeze-drying is currently used. The purpose of lyophilization is to preserve the complete biological and chemical structure and activity of the product. Like many other technical steps, a type of freeze-drying is called sublimation, which occurs naturally. Sublimation refers to the process in which solvents, such as water, directly change from solid to gaseous state like dry ice. Traditional drying can cause materials to shrink and destroy cells. This will not happen in lyophilization, because the solid composition is supported by the ice in its place. When ice sublimates, it leaves pores in the dry residue.
The freeze-drying process is divided into three stages: freezing, sublimation, and analytical drying. Each stage has corresponding requirements. Different materials have different requirements. The difference in process design and control methods at each stage is directly related to the quality and quality of freeze-dried products. The performance of freeze-drying equipment.
1. Freezing stage Freeze-drying must first freeze the raw materials so that the water in the raw materials becomes ice, ready for the next stage of sublimation. The freezing temperature and freezing speed are the key to control. The temperature must be below the freezing point of the material, and different materials have different freezing points. The freezing speed is directly related to the size of the ice crystal particles in the material, and the size of the ice crystal particles is directly related to the structure of the solid material and the sublimation rate. Generally, it is required to complete the freezing of materials within 1-3 hours and enter the sublimation stage.
