Chemical raw material microwave heating dryer

Chemical raw material microwave dryer powder microwave drying sterilizer material medium is composed of polar and non-polar molecules. Under the action of electromagnetic field, these polar molecules change from a random distribution state to an orientation arrangement according to the direction of the electric field. Under the sensitive microwave electromagnetic field in Hubei, these directional movements constantly change at a frequency of billions of per second, causing intense molecular motion and magnetic friction, thereby generating heat and directly converting electrical energy into thermal energy within the medium. It can be seen that microwave heating is the heat generated by the loss of electric field energy by the dielectric material itself, and the dielectric constant and dielectric loss tangent of different dielectric materials are different. Therefore, the thermal effect under the action of microwave electromagnetic field is also different. Substances organized by polar molecules can absorb microwave energy well. The strong polarity of the water molecule layer is a good medium for absorbing microwaves. The characteristics of microwave drying are: 1. Fast heating, short drying time, and uniform heating. Microwave heating is different from traditional heating methods in that it uses microwaves to heat materials as a whole without the need for thermal conduction, allowing for the drying process to be completed in a short amount of time; The selective heating of microwave is uniform, and there will be no phenomenon of external dryness and internal wetness caused by uneven heating, resulting in high product quality. 2. Low temperature drying sterilization has good sterilization effect and is convenient for production and processing in various industries. The bactericidal effect of microwaves is the result of the dual effects of thermal and biological effects of microwave electric fields. 3. Save energy consumption, reduce power consumption, and lower production costs. Microwaves directly act on materials, so there is no additional heat loss. The air inside the heating chamber and the corresponding container do not heat up, so the thermal efficiency is high, unlike far red .....
