Detail

Conventional black tea production process, killing/fixation is the use of frying furnace through high temperature to destroy the active oxidative enzymes in the fresh leaves, thereby inhibiting the oxidation of active enzymes such as tea polyphenols, evaporate the water in the fresh tea, so that the tea leaves become soft, easy to knead and shape, while letting the fresh tea in the green odor to emit, increase tea aroma , improve tea quality.

The principle of black tea microwave drying equipment, compare with conventional hot air drying, microwave machine heat emission is the opposite. The drying method of hot air drying equipment affects the outward evaporation of water. And microwave equipment is to penetrate the tea internal heating, so that the parts with high water content warm up faster. Therefore, in the microwave drying process, the water molecules are transferred quickly from inside to outside, and the drying speed is obviously faster than the hot air dryer.

In black tea drying, microwave drying sterilization equipment hasthe following advantages:

fast drying speed; product quality; due to the surface temperature of the tea is not too high, less changes in chlorophyll, color green and green and resistant to storage, less loss of aroma, drying and uniformity; at the same time, due to the fast evaporation of water, easy to form a porous, rehydration of products is good, hot water brewing, the tea aroma, as well as other beneficial substances are easy to dissolve.

Black tea production, tea drying is the last process, but also the key to determine the quality of tea. After the end of fermentation, the first use of high temperature to destroy the enzyme activity, inhibit the tea to continue fermentation, fixed fermentation process formed in the color and flavor. And under the action of dry heat, to develop. Then evaporate the water and improve the tea aroma. Black tea microwave drying and killing equipment, is the first choice for enterprises to produce high-quality black tea, its economic benefits and production efficiency, can help enterprises to open up a wide range of markets and enhance the brand image. At the same time,energy saving and environmental protection, does not produce waste gas waste water and other pollutants. Effectively improve the harsh working environment of high temperature in the tea production
