Tunnel microwave dryer
Tunnel microwave dryer is a new type of drying equipment, the production efficiency is high, the operation cost is low, and it is a kind of efficient and environmental protection energy saving equipment; especially for the food in the drying, while containing sterilization and preservation role. This equipment has been widely involved in pharmaceutical, food, chemical, building materials and other industries
The tunnel type microwave dryer consists of microwave heater, microwave generator, microwave suppressor, mechanical transmission mechanism, exhaust exhaust system and automatic control system, the main components of the equipment are made of 304 # stainless steel, in line with the GMP standard pharmaceutical equipment, the whole machine adopts modular design, which is easy to clean and easy to operate.
When the equipment is running, the microwave is generated by the microwave generator firstly, and then is fed into the microwave heater through the energy feeding device; the material is sent to the microwave heating chamber by the transmission system. At this time, the moisture in the material can be heated and evaporated under the action of microwave energy, and the water vapor can be dried through the dehumidification system to achieve the purpose of drying. The bacteria in the material were killed by biological effects and thermal effects produced by microwave electromagnetic field. Because the microwave is directly acting on the material, the drying temperature is low, the speed is fast, and the loss of the effective ingredients in the material is very small.
1、The controlled microwave emission system is controlled by a waveguide, in this way, the microwave drying can be realized, the material uniformity is very good, and the microwave transmitting power is not attenuated and not crossed, meanwhile, the service life of the equipment can be effectively guaranteed.
2、Equipped with microwave suppressor in the import and export of equipment, microwave leakage can meet the national safety standards≤5mw/cm2.
3、The machine adopts modular design, touch screen as a man-machine interface, controlled by the PLC, the core electronic components are imported.
4、Material transfer system is equipped with Japan Sanken frequency converter speed control, the speed adjustment of the device is realized from the zero speed to the highest speed in the true sense.
5、The equipment is equipped with infrared thermometer imported from the United States. The temperature is accurate and the performance is stable, so that the temperature control is accurate. Through the setting of temperature, the microwave power can be adjusted automatically on all kinds of materials to meet the microwave energy input. Temperature fluctuations ≤ 3 ℃.
