Freeze dryer knowledge
The freeze dryer is a kind of drying equipment. It consists of refrigeration system, vacuum system, heating system and electrical instrument control system. It has been widely used in recent years, especially in the pharmaceutical industry.
Safety precautions: 1. When the equipment is installed, it must be grounded reliably. 2. Do not frequently (continuously) swing the key. The freeze dryer system needs to wait for more than three minutes between start and stop. 3. When using, it must be confirmed that the compressed air pipeline air pressure and power supply system voltage are in accordance with the scope of use of the machine. 4. The freeze dryer should be installed on a solid floor and should not be installed on other equipment.
Features of the freeze dryer: 1. The refrigeration compressor adopts a high temperature type fully enclosed refrigeration compressor with stable operation, low noise, reliable performance and long power saving life. 2. The heat exchanger and condenser are made of high-quality and high-efficiency threaded pipe with high heat transfer coefficient, so the volume is small and the structure is compact. The cylinder material is made of stainless steel or carbon steel galvanized to avoid secondary pollution of compressed air. 3, the equipment structure is reasonable design, easy to maintain, box-shaped shape, beautiful and generous.
The future research focus of drying technology and equipment: 1) transform existing equipment to meet the requirements of drying new products; 2) combine various dryers to complete the drying of one product; 3) develop special drying equipment; 4) develop Superheated steam drying technology; 5) Development of new drying equipment; 6) Application of computer technology to improve the level of drying technology (theoretical research, design, operation, control).
Expert reminder: Check the drainage every day. If the moisture from the freeze dryer cannot be removed in time, it will affect the dryness of the compressed air.
