Summary:

Vacuum drying involves heating and drying the material under vacuum conditions. It uses a vacuum pump to remove moisture, creating a vacuum environment, which significantly accelerates the drying rate of the material while also saving energy. Vacuum drying equipment is categorized into static dryers and dynamic dryers. The YZG cylindrical and FZG square vacuum dryers are static vacuum dryers, while the SZG bi-conical rotary vacuum dryer is a dynamic dryer. In static dryers, the material remains stationary during drying, preventing damage to its shape, and can be sterilized before drying. In dynamic dryers, the material is continuously moved, ensuring more even and thorough drying. The boiling point of the solvent in the material is reduced under vacuum conditions, making it suitable for drying unstable or heat-sensitive materials. Vacuum dryers also have excellent sealing properties, making them ideal for drying materials that require solvent recovery or contain highly irritating and toxic gases. Vacuum drying equipment is widely used in industries such as pharmaceuticals, chemicals, food, and dyes, and meets the air quality requirements of the "GMP" (Good Manufacturing Practices) for pharmaceuticals.
