Microwave drying machine:
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.
Usage of microwave dryer:
Food microwave dryer 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 solvent extraction plant microwave drying machine: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.
Characteristic - high efficiency of energy conversion and fast heating speed. Microwave oven itself does not heat, but microwave energy through the material, the polar molecule in the material rubs against each other and generates internal heat. The liquid inside the processed material is instantaneously heated, vaporized, pressurized and expanded, and the macromolecule material in the component is denatured by the expansion force of gas, and becomes a multi-microporous material with network structure characteristics and stereotyping.asy to use and operate. Microwave power and transmission belt speed can be steplessly adjusted without thermal inertia. It can be switched on and off immediately and is simple and easy to control. Improve the production environment. Microwave equipment has no waste heat radiation, no dust, no noise, no pollution, and is easy to achieve the detection standard of food hygiene.
