Product Description

Industrial Tunnel Conveyor Belt Type Microwave Tea Fixation Machine :

Tea processing steps mainly as follows:

Plucking--Wilting--Disruption--Fermentation--Fixation--Yellowing--Shaping--Drying--Aging

Different classes of tea undergo the same process with only minor differences. Depending on which step is modified and by how much decided what type of tea is being made.

1. Microwave application in tea fixation :

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 weigLD loss of tea after fixation treatment, partial chlorophLDl 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.

2. Advantages of microwave tea fixation machine:

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. Repeated experiments and practice show that after treatment with microwave heating technoloLD, has excellent characteristics of high-grade tea, dried tea appearance even, colour and lustre is green, fresh and pure taste, aroma rich, tender leaves evenly brigLD.

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.
