Description

Hot air withering device for white tea

Technical Field

The utility model relates to the technical field of white tea withering, in particular to a white tea hot air withering device.

Background

The natural withering is to uniformly spread fresh leaves on a bamboo curtain or a bamboo screen, and to carry out the process at a shade and dry place through air circulation and also to make withering and carving. Spreading the picked fresh leaves according to a certain thickness, airing to enable the fresh leaves to be in a wilting state, and in the withering process, making the fresh leaves change in a series: the moisture is reduced, and the blade becomes soft from crisp and hard, so that the blade is convenient to knead into strips; the activity of enzyme substances contained in the leaves is enhanced, fresh leaf components such as starch, protein, insoluble protopectin and the like are promoted to be decomposed and converted, effective substances such as glucose, amino acid, soluble pectin and the like which are beneficial to the quality of the finished tea are generated, and polyphenol substances are oxidized to different degrees. Normally and effectively withering, so that the grass smell of the fresh leaves is eliminated to generate faint scent, the fresh leaves have fruit fragrance or flower fragrance, and the finished tea has mellow taste without bitter. The withering requires proper conditions of temperature, humidity, and air circulation. The traditional withering methods include solar withering (sun-drying), indoor natural withering (spreading-drying) and compound withering using both methods, and now manually controlled semi-mechanized withering equipment, i.e. withering tanks, are also used. The first procedure in the production of white tea, black tea, green tea and other tea in China is withering, but the degree is different. The white tea withering degree is the heaviest, the water content of fresh leaves is required to be reduced to below 40%, the black tea withering degree is the heaviest, the water content is reduced to about 60%, the green tea withering degree is the lightest, and the water content is required to be between 68 and 70%;

for example, application publication number CN208956897U, a white tea withering device convenient to use, including a box body, the bottom of box inner wall is provided with a first heating device through the recess, be provided with the storage net on the bottom of box inner wall, the front and back both sides of box inner wall are provided with first gyro wheel, the quantity of first gyro wheel is provided with two, and the surface of two first gyro wheels is connected through first belt drive, the front and back both sides of box inner wall are located the upper portion of first gyro wheel and are provided with the second gyro wheel;

the white tea device that withers that above-mentioned application was used carries out even hot-blast to tealeaves, upper and lower twice conveyer prevents that white tea from standing still, can make white tea carry out even amortization through the cooperation use of component simultaneously, effectually wither, hot-blast simultaneously and the removal of moisture, unnecessary waste has been reduced, the work efficiency of withering has been promoted, simultaneously effectually deposit and keep warm, make things convenient for subsequent processing, but it adopts the mode of tiling tealeaves to wither, tealeaves gathers easily, be difficult to release moisture, wither inefficiency, therefore market urgent need develop white tea hot-blast device that withers helps people to solve current problem.
