Automatic Continuous Microwave Tea Fixation Machine

We are connected in making, exporting and supplying Continuous Microwave Tea Fixation Machine in Linyi, Shandong, China. Tea processing is a traditional industry in China. In order to improve the processing quality and industrial modernization of tea, it is necessary to apply new science and technology in tea primary processing industry and deep processing industry, and advanced microwave technology has a good application prospect in tea. Microwave refers to the ultra-high electromagnetic wave between the radio and the light wave at 3OMHz-300000MHz. Currently, microwave devices used in the food industry have a center wavelength of 0.328 m (frequency 915 MHz) or 0.1225 m (frequency 2450 MHz).
The production of green tea, oolong tea, all need to heat fixation treatment, passivate the activity of polyphenol oxidase, evaporate moisture content, volatile grass smells, soften the organization. Now commonly used pan-fired method to deal with fixation, a few places using steam fixation method.
The test results show that the microwave and the traditional processing way .the tea quality is good, no obvious difference, but the short microwave fixation time(1/8 time of pan-fired) and can be continuous processing. And steam fixation, because of high steam moisture content, the outer of raw material affected by high temperature, therefore almost no weight loss of tea after fixation treatment, partial chlorophyll was destoryed,the raw material contains nutrients loss along with the condensation water,quality is not ideal.

The application of microwave fixation for the tea is the main source of heat effect. When magnetron produce microwave ,effect on tea leaves, polar molecules inside tea affected by microwave cyclical change, cyclical activities accordance with microwave.Because high microwave frequency, make tea internal molecular collision at a high speed and generate a lot of friction heat, rapidly increase the temperature of the material,

Make tea molecules inside a lot of friction heat resulting from the high speed collision rapidly raise the temperature of the material, so as to achieve rapid heating effect.
