Abstract

The invention discloses a visible tea yellowing device and a yellowing method, and relates to the technical field of tea processing. The yellowing device comprises a rack and a rack-mounted yellowingcylinder, wherein a water tank for heating a lower cylinder wall is connected with the lower cylinder wall of the yellowing cylinder; a material inlet is mounted at the top part of the yellowing cylinder; a material outlet is mounted at the bottom of the yellowing cylinder; a rotary opening and closing door is mounted on the material outlet; a vent hole is formed at one end of the yellowing cylinder; a yellowing cylinder side door is mounted at the other end of the yellowing cylinder; a hollow shaft is mounted rotationally along the axial direction in the yellowing cylinder; a power device isconnected with one end of the hollow shaft; the other end of the hollow shaft communicates with the inside of a water tank by an air guide pipe; air flow holes are uniformly distributed in the hollowshaft; and a plurality of turning devices are mounted along the axial direction on the outer wall of the hollow shaft. By adopting the visible yellowing device disclosed by the invention, the internalenvironment of the yellowing cylinder can be easily adjusted and controlled, so a yellowing process of yellow tea is convenient in operation and uniform in yellowing effects, and the yellowing quality and performance of the yellowing device are improved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a device for visible yellowing of tea and a method for yellowing of tea. Background technique [0002] Yellow tea is a unique tea in my country. Its quality is characterized by "yellow leaves and yellow soup". The aroma is clear and pleasant, and the taste is mellow and refreshing. . After the fresh leaves are picked and spread out, the enzyme activity is completely destroyed by high temperature killing. The polyphenolic compounds undergo non-enzymatic auto-oxidation under the action of heat and humidity, producing some pigments, and at the same time, other chemical substances in the tea also undergo some corresponding changes. Boiled yellowing is a unique process of yellow tea processing, and it is also a key process for forming the unique quality of yellow tea. This process is mainly affected by factors such as water content of fresh tea leaves, the method of yellowing, ...
