Extract microwave vacuum drying oven

Microwave vacuum dryermain purpose
The equipment is used for low-temperature drying of thermosensitive traditional Chinese medicine solid preparations and can also be used as a vacuum concentration equipment. It has a fast drying speed and can greatly improve product quality. It has the characteristics of high efficiency, uniform heating, easy control, and convenient installation and maintenance. It can also be used for drying, heating, sterilization, and maturation of pharmaceuticals, biological products, and agricultural and sideline products, with ideal drying effects on various pills and granular materials. The microwave low-temperature vacuum drying equipment also has the functions of disinfection and sterilization, with linearly adjustable power, intelligent control, controllable environment and temperature. The products produced are safe and hygienic, and can extend the shelf life.

Microwave vacuum dryerworking principle
During equipment operation, microwaves are generated by a microwave generator and input into a microwave heater through an energy feeding device; The material is sent to the heater by the transmission system, and at this time, the moisture in the material is heated and evaporated under the action of microwave energy. The water vapor is removed through the dehumidification system to achieve the purpose of drying. The bacteria in the material are killed by the biological and thermal effects generated by the microwave electromagnetic field. Due to the direct action of microwaves on materials, the drying temperature is low and the speed is fast, resulting in minimal loss of active ingredients in drugs.

Structure and characteristics
Thermally sensitive materials can be quickly dried, dehydrated, and concentrated at room temperature, and the dehydration temperature of the material can be controlled below 40 ℃. Infrared temperature measurement, digital timing, adjustable power, intelligent control, simple operation, uniform heating, saving 50% energy compared to conventional process equipment. In addition, it can also be used for drying, dehydration, and concentration treatment of many easily oxidizable materials. The material rotates in three dimensions, with a large paving area and various levels of equipment available for selection.
