Chemical and Pharmacy Powder Microwave Drying Equipment
Pipeline microwave drying equipment is different from traditional drying method, and its heat conduction direction is the same as water diffusion direction. Compared with traditional drying methods, it has many advantages, such as high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality, so it has been paid more and more attention in various fields of drying.
Microwave drying sterilization equipment is the result of the combination of thermal and biological effects of electromagnetic field. The thermal effect of microwave on bacteria is to change the protein, make bacteria lose nutrition, reproduction and survival conditions and die.Selective heating of microwave machine: Because water molecule absorbs microwave best, the part with high water content absorbs microwave power more than the part with low water content in the same unit time. This is the characteristic of selective heating, which can be used to achieve uniform heating and sterilization. Energy saving and high efficiency of microwave machine. Microwave acts directly on materials, and air does not absorb microwave. Therefore, without additional heat loss, the air in the furnace and the corresponding container will not heat. The temperature of the air is caused by the heat energy radiated from the material when the temperature rises above the ambient temperature. Therefore, microwave heating has very high thermal efficiency, and the production environment has been significantly improved. Compared with far-infrared heating, it can save more than 30% electricity.
Characteristics of chemical and pharmacy powder microwave drying equipment:Inside and outside at the same time, the drying speed is fast and the drying time is short.
Selective heating. Microwave heating is related to the nature of the substance itself. In a certain frequency microwave field, water absorbs much more heat than other dry materials because its dielectric loss is greater than that of other materials. At the same time, because microwave heating is carried out at the same time inside and outside the surface, the internal moisture can be heated quickly and evaporated directly.High thermal efficiency. Because the heat directly comes from the inside of the drying material, the heat loss in the surrounding medium is very little. In addition, the microwave heating chamber itself does not absorb heat and absorb microwave, and all the heat is emitted to the material, so the thermal efficiency is high.
