microwave drying It is a method of internal heating. The wet material is in the microwave high-frequency electric field with extremely short oscillation period. The water molecules inside the wet material will be polarized and orderly arranged along the direction of the microwave electric field, and then quickly rotate with the interactive change of the direction of the high-frequency alternating electric field, resulting in severe collision and friction (hundreds of millions of times per second). As a result, part of the microwave energy is converted into molecular motion energy, It is expressed in the form of heat, which makes the water temperature rise and leave the material, thus drying the material. That is to say, after microwave enters the material and is absorbed, its energy is converted into heat energy in the material dielectric. It has the advantages of large 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 technology has been used in food industry, material chemical industry, pharmaceutical industry, mineral mining industry, ceramics industry, laboratory analysis, wet natural rubber processing, etc.

characteristic:

The unique microwave source and its control technology are adopted to ensure the long-term continuous and stable operation of the microwave source system in various complex environments Magnetron Normal service life of ≥ 1 year;

The high efficiency microwave transmission system specially made according to the standard is adopted to feed energy evenly to the materials, so as to ensure that the materials are dried evenly and effectively avoid the phenomenon of excessive local temperature of materials;

The original mathematical model and the drying process requirements are combined for scientific cavity design to ensure high dehydration efficiency and avoid

Avoid the occurrence of "hot spots", "sparking", "splashing", "burning belt" and other undesirable phenomena in the cavity;

The safe and reliable microwave shielding design ensures that the microwave leakage is less than 2mw/cm2, which is far superior to the national standard;

Compared with traditional drying methods (hot air, steam, electric heating, etc.), microwave drying has the following remarkable characteristics of "high quality, high efficiency, energy saving, and environmental protection":

① Realize pollution-free and uniform drying of materials, and greatly reduce drying temperature;

② The drying speed is usually increased several times, and the production efficiency is greatly improved;

③ Drying energy consumption is usually reduced by more than 50%;

④ Realize safe and clean production.
