Introduction
The microwave is an electromagnetic wave having a frequency of 300 MHz to 300 GHz. The substance in the heating medium in the water molecule is a polar molecule. It changes rapidly under high-frequency magnetic field, and its polar orientation changes with the change of external electric field, which produces the interaction between molecular motion and friction. This microwave field can convert the heat in the medium into heat energy. The temperature rises, heats and puffs a series of physical and chemical processes to achieve the purpose of microwave heating and drying.
Feature
Drying: The microwave dryer is used to dry material in a short time.
Sterilization: The fungus, mycetes and others can be killed by the microwave dryer during the drying process.
Fast and evenly: The microwave dryer can change to be heat within several seconds,so the equipment is very efficent.
Keeping fresh: The sterilization is with lower temp, so the color,taste and nutrition of the tea can be protected well.
Safe: The microwave is passing in the metal covered rooms and waveguide without leaking. It will not generate extra heat and pollution.
Simple to operate: The PLC system is simple, stable, safe and friendly,so it is convenient to use.
Application
Widely used in food, medicine, chemical industry, building materials and other industries; suitable for tea, honeysuckle blue, soybean products, dairy products, dried meat, preserved fruit and other leisure food, as well as nuts, rare mountains, dehydrated vegetables, seasonings, agricultural and sideline local specialties, grains and cereals, fodder drying, dehydration, ripening, sterilization and preservation of traditional Chinese medicine; Sterilization and drying of materials, pills and extracts, drying of paper products, bamboo and wood products, textiles, rubber products, leather, shoes, ceramics, refractories, building materials, etc.
It is suitable for materials with low water content and high added value.
It is not suitable for materials with high water content, low added value and aluminum foil packaging (microwave can not penetrate).
