Microwave drying technology of drying technology

Microwave drying technology from the theory, it can solve all the drying requirements, its emergence solves many drying problems, such as small moisture drying, viscous material drying, embryo, making pieces of drying, cake drying, uniform drying, depth drying, rapid drying, energy-saving drying, and a series of high-demand drying. Because microwave has the ability to penetrate the material, so microwave drying technology is different from heat conduction drying is the whole drying method, its drying speed is very fast, good product quality, realize continuous industrial production, equipment covers an area of small, efficient environmental protection and energy saving characteristics, is constantly replacing the traditional drying technology.

Characteristics of microwave drying equipment

1, uniform and thorough: the part with high water content, absorbing microwave more, generating heat, and vice versa, the less; at the same time, the product is inside and outside of the overall heating, there is no thermal inertia, there is no heat transfer loss, fast drying speed. Microwave directly penetrate the product, radicalization of water molecules, generating heat, the internal temperature is slightly higher than the external temperature, can try to avoid temperature gradients and produce "shell" and slow evaporation of water shortcomings.

2, simple control: due to the microwave power can be quickly adjusted and no inertia characteristics, combined with PLC automatic control system in time to control, easy to adjust and determine the process parameters.

3, improve the quality: drying in a low-temperature oxygen-free environment, better guarantee the quality of the product.

4, to maintain the original color: due to the microwave drying time is short, to solve the traditional drying time is long, humidity is easy to lead to the product change color, especially for valuable medicinal herbs, traditional Chinese medicine extracts, seafood products, etc., it is an ideal drying method,

5, energy saving and environmental protection: compared with the conventional electric heating drying method, microwave drying can generally save point 50%, the equipment used is microwave radiation The equipment adopts microwave radiation to transmit energy, and the medium is heated as a whole. No other heat transfer medium. Avoid the shortcomings of slow heat conduction under vacuum condition, so the speed is fast, the efficiency is high, the drying cycle is greatly shortened, the energy consumption is reduced. No noise, no toxic gas and liquid emissions, belong to the environmental protection drying technology.
