Fungus and Mushroom Microwave Drying Machine

Microwave drying machine, also known as microwave dryer, is a kind of microwave dryer used to dry food, medicinal materials, wood, building materials, cardboard and other materials. Compared with traditional drying equipment, the characteristics of microwave dryer are: fast drying speed, high efficiency, environmental protection and energy saving, and it is a new type of equipment responding to low-carbon economy. Its working principle is to use the penetrating heating of microwave to raise the temperature of the material, to vaporize and evaporate the water vapor in the material, and to drain the evaporated water vapor from the dehumidification system to achieve the purpose of drying the material.

Electromagnetic radiation drying is to use the electromagnetic induction or infrared radiation effect of microwave to heat and dry materials. Different from other external heating drying methods, this drying method is a method of uniform heating from both outside and inside of the material. Therefore, this drying method has a short time, does not deteriorate or coke due to overheating, and its drying products are of good quality, especially the drying effect of heat-sensitive food is more satisfactory.The microwave drying system is mainly composed of microwave generator, power supply, waveguide device, heater, cooling system, transmission system and control system . The microwave tubes used for heating and drying are mainly klystrons and magnetrons. Klystron is often used in high frequency or high power applications. Microwave generated by microwave tube is transmitted to heater through waveguide device. The heaters are mainly box type, plate type and waveguide type.

Fungus and mushroom microwave drying machine is mainly used for paste food, powder food, granular food, agricultural products, and other products that need to be dried. Microwave dryer can be designed and manufactured according to different needs of different products. Characteristics of food microwave dryer.Microwave drying is an efficient, energy-saving, stable, reliable, simple equipment, easy operation and new technology. Microwave dryer is characterized by continuous production of equipment, only need electricity, no need for other energy, can quickly dry materials, equipment occupies a small area, pollution-free, simple operation; no need for preheating and no energy loss after shutdown. Less labor, high quality products. The advanced equipment is a high-tech product which can not be replaced by other equipment.

Heating Principle of Microwave Dryer:
Microwave refers to electromagnetic waves with frequencies ranging from 300 MHz to 300 MHz. The water molecule in the heated medium material is a polar molecule. Under the fast changing high frequency electromagnetic field, its polar orientation will change with the change of external electric field, resulting in the movement of molecules and mutual friction effect. At this time, the field energy of microwave field can be transformed into heat energy in the medium, which makes the material temperature rise, and produces a series of physical and chemical processes, such as heating and expansion, to achieve the purpose of microwave heating and drying.
