Fresh tea leaf treatment device and treatment method thereof

Abstract

The invention relates to a fresh tea leaf treatment device and a treatment method thereof. The fresh tea leaf treatment device comprises a withering bed and a heating device; a fan is fixedly arranged above the heating device; the fresh tea leaf treatment device is characterized in that a PTC heating body is arranged in the heating device; an air guide plate is arranged at the front end of the heating device; the fan blows air from top to bottom, airflow is heated through the PTC heating body, and hot gas moves towards the withering bed; a sunlight withering simulation device is fixedly arranged above the withering bed; a luminous body adopts a carbon fiber thermal inductance tube and only radiates 4.5-13.4 mu m far infrared rays, so that the fresh tea leaves can be uniformly heated from inside to outside, the heat conversion efficiency is high, and the energy is saved by 30 percent or above compared with that of a common metal heating body; and the sunlight withering simulation device comprises a louver board and a far infrared emission device fixed on the louver board. The air flow flows transversely after being heated by the PTC heating body and flows to the withering bed, and the flow speed of the transverse air flow is not high, so that the problems that the traditional withering bed cannot be heated at the position close to the fan and has negative pressure can be effectively solved, and the tea withering effect is uniform and good.

Description

technical field [0001] The invention relates to the technical field of tea withering, in particular to a device for processing fresh tea leaves and a processing method thereof. Background technique [0002] Withering is the first process in black tea processing and is the basis for the formation of black tea quality. Under certain temperature and humidity conditions, the harvested fresh leaves are thinly spread, and the water is properly lost to reduce the tension of the fresh leaves. After the fresh leaves wither, the water content decreases, the leaf quality becomes soft, the leaf color becomes dark, the grass smell gradually weakens, and the fragrance and flower fragrance begin to appear. . [0003] In the traditional withering device, the fan is installed on the side, blowing air directly inside the withering bed, and the hot air cannot cover the area about one meter away from the withering bed. If the air deflector is used, it is difficult to adjust the balance of hot...

Problems solved by technology

[0003] In the traditional withering device, the fan is installed on the side, blowing air directly inside the withering bed, and the hot air cannot cover the area about one meter away from the withering bed. If the air deflector is used, it is difficult to adjust the balance of hot air when the number is small, and it is not conducive to the passage of airflow when the number is large

And because the blower blows directly, it will cause negative pressure and vacuum in the area near the fan, and the tea leaves will be pressed tightly on the withering bed, resulting in poor withering effect, and the withered tea leaves have the problem of uneven withering
