Freeze dryer is a kind of drying equipment, which is composed of refrigeration system, vacuum system, heating system and electrical instrument control system. It has been widely used in recent years, especially in pharmaceutical industry, and plays an important role.
Safety precautions:
1. When the equipment is installed, it must be grounded reliably.
2. Do not swing the key frequently (non-stop), the freeze dryer system needs to wait more than three minutes between start-up and shutdown.
3. When using, it must be confirmed that the air pressure of the compressed air pipe and the voltage of the power supply system conform to the scope of the machine.
4. The freeze dryer should be installed on the horizontal and firm ground, and should not be installed on other equipment bodies.
Features of freeze dryer:
1. The refrigeration compressor adopts high temperature hermetic refrigeration compressor with stable operation, low noise, reliable performance, power saving and long service life.
2. The heat exchanger and condenser are made of high quality and high efficiency threaded tubes with high heat transfer coefficient, so they are small in size and compact in structure. The cylinder is made of stainless steel or carbon steel and galvanized to avoid secondary pollution of compressed air.
3. Equipment structure design is reasonable, easy to maintain, box shape, beautiful and generous.
The future research focus of drying technology and equipment is as follows
1. Transform the existing equipment to meet the drying requirements of new products.
2. Various dryers are combined to complete the drying of a product.
3. Develop special drying equipment.
5. Develop new drying equipment.
6. Apply computer technology to improve the level of drying technology (theoretical research, design, operation and control).
Experts remind: check whether the drainage is normal every day. If the moisture out of the freeze dryer can not be removed in time, it will affect the dryness of compressed air.
