Tunnel Finished Tea Drying Sterilization Machine

The applications of microwave equipment for the tea:

Fixation,drying, sterilization,enhance flavor, insecticide. Improve tea quality, multi-function machine, is an indispensable equipment for tea processing.

Tea fixation is one of the initial processes of green tea, yellow tea, black tea, oolong tea etc,is also one very important process.By using the characteristics of microwave rapid heating, the enzymatic oxidation of tea polyphenols in fresh leaves was inhibited by high temperature destruction and passivation, and part of water in fresh leaves was vaporized to make tea soft and easy to knead. The tea treated by microwave is a new and efficient technology with green color, good shape and fresh tea flavor.

1) Fast heating speed. The microwave directly acts on the tea leaves, heating the inside and outside of the tea leaves at the same time, without any conduction process, without preheating, turn on the machine and can process directly.

2) Heat evenly. Microwave fixation is that the electromagnetic wave generated by the magnetron is evenly irradiated on the tea leaves, , without the phenomenon of coke leaves and coke edges.

3) Less nutritional loss. Tea stays inside the microwave heating box for a short time, does not require air and steam to conduct heat, so can retain the nutrients.

4) High efficiency and save energy . Microwave among all processes of drying uses least amount of power, as the air, vessel and atmosphere does not get heated and energy wasted in air. 100% power energy goes towards heating /drying.Today grid electricity is the cheapest source of energy more than coal or gas, and does not require a Stoker to attend the heat source.

5) Improve tea quality. The surface temperature of the tea leaves is not high when microwave fixation, and there is no need to blow and cool when the leaves emerge, so the chlorophyll changes less, the color is emerald green, and the aroma loss is less. At the same time, due to the fast evaporation of water, it is easy to form porosity. The soluble matter is easily dissolved during the time.

6) Improve the hygienic quality of tea. There is no need to burn coal and wood , there is no pollution from smoke and dust. At the same time, realize the automation and continuity of tea processing, avoid the secondary pollution caused by conventional processing well.
