Industrial Microwave Tea Leaf Processing Machine/Tea Drying Machine/Tunnel Tea Dryer / Continuous Tea Dehydrator /Tea Fixation Machine

1. Microwave application in tea drying process:

General hot air drying process, material external heated, surface drying, heat transfer inwards, the direction and water diffusion direction in the opposite direction, affect the moisture to evaporate.But microwaveis an internal heating, The part of high water content heat up faster.So in the microwave drying process, water migration speed from the inner to the outer is high, drying speed is significantly faster than hot air drying.

2. Microwave application in tea fixation process:

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.

3. Microwave Advantages in Tea Drying/Fixation Process:

1). Stable quality. Different seasons,different tea ,different time ,the fresh picked tea leaves have

differences in intinal water content,fresh degree etc,microwave can flexibly adjust fixation,drying

data according to these characteristics,then can make every kind tea reach the ideal fixation effect.

2). Improve tea quality. Because tea surface temperature is not too high, less chlorophyll

changes,color and lustre is green ,less aroma loss ;

3). Improve tea health . Microwave fixation, microwave drying don’t need coal or wood, no smoke and dust pollution, at the same time realize automate the tea continuous processing,, avoiding the conventional process to produce secondary pollution.

4) Uniform drying;

5) Due to the fast evaporation speed, easy to form porous, good water complex content easy to dissolution when making tea.

6) The microwave processing of tea,also have a sterilization antifungal function .While drying tea,also can sterilize and kill insects and larvae.

Small Tea Leaf Processing Machine --Tunnel Continuous Type, often colloquially shortened to microwave, is a kitchen appliance that heats food by bombarding it with electromagnetic radiation in the microwave dryer spectrum causing polarized molecules in the food to rotate and build up thermal energy in a process known as dielectric heating.Small Tea Leaf Processing Machine --Tunnel Continuous Type heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm of a dense (high water content) food item; food is more evenly heated throughout (except in thick, dense objects) than generally occurs in other cooking techniques. Small Tea Leaf Processing Machine --Tunnel Continuous Type can Sterilize the food during the drying process by heat and the influence on the protein, RNA, DNA, cell membrane and so on.
