Processing method of black tea

Abstract

The invention belongs to the technical field of tea processing and discloses a processing method of black tea. The processing method comprises the steps of withering, kneading and twisting, fermenting and drying. A fermentation device is used for fermenting in the step of fermenting and comprises a fermentation part and a driving part, wherein the fermentation part comprises a support frame, the support frame is connected with pull rods, and the pull rods are connected with fermentation tanks; the fermentation tanks are communicated by virtue of a connecting pipe, and each fermentation tank is provided with a ventilation opening; each fermentation tank is articulated with a baffle plate; each fermentation tank is provided with a gas outlet; the driving part comprises a base, a driving block, a connecting rod, a rotating rod and a motor; the upper surface of the base is flush with the bottom of each fermentation tank, the upper surface of the base is provided with a sliding chute, and the driving block is in sliding connection in the sliding chute; the motor is mounted on the base, and the motor drives the rotating rod to do circumferential motion; and one end of the connecting rod is articulated with the rotating rod, and the other end of the connecting rod is articulated with the driving block. The processing method disclosed by the invention solves the problem of poor tea quality caused by uneven fermentation degree in the tea processing course of the prior art.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a processing method of black tea. Background technique [0002] Black tea, which belongs to fermented tea, undergoes an oxidation reaction during its processing, which changes the chemical components in the fresh leaves. The tea polyphenols are reduced by more than 90%, and new components such as theaflavins and thearubigins are produced, so the tea leaves are red. , and its tea soup is also red, so it is called black tea. Black tea is rich in carotene, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine, leucine, lysine, glutamic acid, alanine, aspartic acid and other nutrients It has the functions of helping the stomach and intestines to digest, promoting appetite, eliminating edema, refreshing and relieving fatigue, promoting body fluid and clearing away heat, etc., so it is widely loved by people. [0003] The processing technology of black t...
