With the development of the situation, the market of microwave drying machine has developed rapidly, and the production enterprises have also made good achievements, innovations in technology and increasing benefits. In fact, drying has a long history, as early as ancient times, people began to use natural conditions for material drying. With the development of the times, they are gradually replaced by manual operation. Instead, microwave drying equipment has gradually developed.
Characteristics of Fish Feed Pellet Microwave Drying Machine：Energy Saving of Microwave Drying Equipment.Because the substance containing water is easy to absorb microwave and heat, there is almost no other loss except a small amount of transmission loss. Therefore, it has high thermal efficiency and energy saving. Microwave drying equipment can save more than 1/3 energy than infrared drying.Microwave drying equipment dries rapidly.Microwave drying equipment is completely different from traditional drying methods. It is a process in which the dried material itself becomes a heater without heat conduction.
Safety and harmlessness:
Because microwave energy of microwave drying equipment is controlled to work in metal drying chamber and waveguide tube, microwave leakage is very little, there is no radiation hazard and harmful gas emission, no waste heat and dust pollution, neither food pollution, microwave drying equipment nor environmental pollution. Anti-mildew, sterilization and preservation of microwave drying equipment.Microwave drying equipment has thermal and biological effects. Microwave drying equipment can sterilize and prevent mildew at lower temperature. Because of its fast drying speed and short drying time, it can preserve the activity of materials and vitamins, original color and nutritional ingredients in food to a great extent. Advanced Technology.As long as microwave power is controlled, microwave drying equipment can achieve immediate drying and termination. The programmable automatic control of drying process and drying process specification can be carried out by using man-machine interface and PLC.
Microwave drying equipment is a kind of microwave drying equipment, which is obtained by the special movement of electrons in the magnetic field through DC or 50Hz alternating current on the electro-vacuum device or semiconductor device. This motion can be explained simply as follows: from the point of view of dielectric structure, one kind of molecule is called electrodeless molecular dielectrics, the other is called polar molecular dielectrics. Microwave drying equipment in general, they are arranged irregularly.In an alternating electric field, the polar molecular orientation of these media changes with the polarity of the electric field, which is called polarization. The stronger the applied electric field is, the stronger the polarization effect of microwave drying equipment will be. The faster the polarization of the applied electric field changes, the faster the polarization will be. The more intense the thermal movement of molecules in microwave drying equipment and the friction between adjacent molecules will be. In this process, the conversion of electromagnetic energy to thermal energy is completed. When the heated material is placed in the microwave field, the polar molecules of microwave drying equipment swing and rub back and forth with the microwave frequency of billions of times per second. The heat generated by microwave drying equipment is enough to make the material hot-dry in a very short time.
