Principle and structural characteristics of microwave vacuum drying oven

The working principle of the microwave vacuum drying oven: When the equipment is running, the microwave is generated by the microwave generator, and is input into the microwave heater through the energy supply device; the material is sent to the heater by the transmission system
.

At this time, the water in the material is heated and evaporated under the action of microwave energy, and the water vapor is removed by the dehumidification system to achieve the purpose of drying
.

Bacteria in the material are killed by the biological and thermal effects generated by the microwave electromagnetic field
.

Since the microwave directly acts on the material, the drying temperature is low, the drying speed is fast, and the loss of the active ingredient in the medicine is very small
.

Main application of microwave vacuum drying oven: Microwave vacuum drying oven is used for low-temperature drying of heat-sensitive traditional Chinese medicine solid preparations, and can also be used as vacuum concentration equipment
.

The drying speed is fast, which can greatly improve the product quality
.

It has the characteristics of high efficiency, uniform heating, easy control, convenient installation and maintenance,
etc.

It can also be used for drying, heating, sterilizing and curing of medicines, biological products, agricultural and sideline products, and has a good drying effect on various pills and granular materials
.

Microwave vacuum drying equipment also has the functions of disinfection and sterilization, adjustable power limit, intelligent control, controllable ambient temperature, product safety and hygiene, and can prolong the shelf life
.

Structure and characteristics of microwave vacuum drying oven: Heat-sensitive materials can be quickly dried, dehydrated and concentrated at room temperature, and the dehydration temperature of materials can be controlled below 40°C
.

Infrared temperature measurement, digital timing, adjustable power, intelligent control, simple operation, uniform heating, 50% energy saving than conventional process equipment, in addition, it can also be used for drying, dehydration and concentration of many oxidizable materials
.

The material is rotated three-dimensionally, the paving area is large, and various grades of equipment are available
