Talking about the Advantage of Microwave Drying Equipment in the Application Field of National Economy

The core of microwave drying equipment is microwave generator. At present, the frequency of microwave drying is mainly 2450 MHz. It is mainly used in chemical industry, food, agricultural by-products, wood, building materials, paper and other industries. It can also be used for sterilization of food and agricultural by-products. In the traditional drying process, in order to improve the drying speed, it is necessary to raise the external temperature and increase the temperature gradient. However, it is easy to produce endogenous phenomena of material coke. However, when microwave heating is used, no matter what the shape of the material is, the heat can penetrate evenly, and the puffing effect can be produced, which is conducive to crushing. Under the action of microwave, the drying rate of materials tends to be uniform and the heating is uniform. Moreover, microwave drying technology does not affect the color, aroma, taste and structure of the dried materials, and the active ingredients are not easy to be decomposed and destroyed. Relevant research institutes are beginning to adopt microwave drying instead of traditional drying in order to solve the problem of uneven drying when traditional drying methods are used to dry Sichuan traditional Chinese medicines.

Microwave equipment has fewer supporting facilities, less land occupation, convenient operation and continuous operation, which is convenient for automated production and enterprise management (programmable control by PLC and adjustable temperature). Microwave drying process has a high energy efficiency, because the heat of microwave is directly generated in the wet material, with less heat loss, high thermal efficiency and no environmental and noise pollution, which can greatly improve the working environment. Common applications of microwave drying equipment

First, it is used for processing high added value agricultural products, such as dehydrated vegetables, dehydrated meat products and dehydrated seafood. These semi-finished products or products produced by microwave drying equipment have light weight, good rehydration performance, fresh color and state after rehydration, and are easy to carry, store and transport at room temperature. It can be kept for 3 years. These processed dehydrated products. As a high-grade ingredient. It can be used as ingredients in condiment bags of instant food such as instant noodles and instant rice flour.

2. It is used in the production of condiments. If ginger and garlic are treated at high temperature, the aromatic substances in the two materials are easily destroyed, which leads to the decrease of their content. If garlic and ginger are treated by microwave drying equipment, the flavor and nutrients in raw materials can be well preserved, and high quality garlic powder and ginger powder can be produced.

3. It is used in the production of health products, including royal jelly lyophilized powder, pure snake powder, turtle powder, Cordyceps sinensis, deer antler, ginseng, Spirulina powder, etc.

4. Powders: such as tungsten ore, silicon carbide, silicon material, silicon wafer, silicon rod, diamond, etc.

5. Pharmaceuticals: such as pharmaceutical intermediates, Chinese herbal medicines, pills, powders, etc.

<6. Chemicals: such as inorganic salts, catalysts, rubber auxiliaries, etc.

In the next few years, the domestic microwave drying equipment industry will continue to develop and become an important driving force to promote the development of domestic microwave drying equipment industry. Therefore, the production enterprises should not only carry out fundamental transformation in drying technology, but also carry out comprehensive and multi-level energy-saving technical transformation, vigorously develop and apply the drying technology of renewable energy and industrial waste heat.
