Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to an efficient black tea withering device with a turning and rectifying function. Background Technique

[0002] Tea withering mainly involves spreading the freshly picked tea leaves in a certain thickness to reduce the moisture content of the fresh leaves, making the leaves change from brittle and hard to soft, facilitating subsequent rolling into strips. At the same time, it enhances the activity of enzymes in the tea leaves, is conducive to promoting the accumulation of substances related to tea quality, and prepares for later fermentation. The first process in the production of tea categories such as white tea, black tea, and oolong tea in our country is withering, but the degrees are different. After withering black tea, the water content is required to be reduced to about 60%.

[0003] According to the publication number: "CN204888618U", a black tea withering device includes a machine frame; a hot air stove connected to the bottom of the side wall of the machine frame through a hot air inlet pipe; a hot air flow control valve for controlling the hot air inlet flow rate is also provided on the hot air inlet pipe; the far end of the hot air inlet pipe from the hot air stove is connected to one end of a blower for accelerating the hot air speed; the other end of the blower is connected to a air supply pipe; a wind deflector inclined at a specified angle with the horizontal plane is arranged at the outlet of the far end of the air supply pipe from the blower; a sieve leaf box is arranged at the opening at the top of the machine frame; a temperature control plate arranged at the opening at the top of the machine frame, which is movable and controls the temperature inside the machine frame by changing the opening size. The utility model adjusts the air volume and temperature through the hot air flow control valve and the temperature control plate, prevents the temperature inside the machine frame from being too high or too low and affecting the tea quality. At the same time, a slope-type wind deflector is adopted, which is conducive to the uniform heating of the sieve leaf boxes at the front and rear ends of the machine frame, ensuring uniform withering of the fresh leaves and ensuring uniform tea quality.

[0004] However, in the actual use process, the overall black tea withering device needs to maintain internal hot air and also needs to circulate air inside, and the overall device has low practicability. Therefore, improvements are made according to the above-mentioned problems. Content of the Utility Model
