Abstract

The invention relates to tea processing and particularly discloses a method for processing raw dark green tea. The method comprises the steps of successively carrying out temperature-controlled and humidity-controlled withering, no-pressure low-speed primary-kneading, standing and cool-piling, high-temperature fixation, high-temperature hot-piling, repeated kneading, temperature-controlled and humidity-controlled pile fermentation, gentle-pressing and re-kneading and deblocking and drying on fresh tea leaves which serve as a processing raw material, thereby obtaining the raw dark green tea finished product. By the method disclosed by the invention, the high-quality raw dark green tea which is cord-shaped and compact in appearance and mellow in taste and has fruit and flower flavors can be obtained. According to the method, the endogenous enzymatic oxidation of the tea leaves, the spore enzymatic oxidation of microbes and hyther are effectively utilized, so that the taste of tea is changed into a mellow and smooth taste from the original bitter and astringent taste; the high-quality raw dark green tea has a unique flavor due to the combination of different tea key technologies, and brick-tea products with excellent quality can be processed according to different grades of raw materials.

Embodiment

[0045] This embodiment is used to illustrate the black hair tea processing method of the present invention.

[0046] Such as figure 1 As shown, the method is specifically:

[0047]Take the fresh leaves of one-bud two-leaf and three-leaf tea as processing raw materials, place them in a withering room with a temperature of 30°C (1) and a relative humidity of 75% (2) to wither for 6-8 hours (3), collect the withered leaves until rolling The machine kneaded for 30 minutes without pressurization (4), and at the same time, the speed of the kneading machine was reduced through the frequency converter, and the kneading speed was 30r / min. 260°C roller degreening machine for 4-6 minutes (6), after the degreening is completed, directly pack it into an airtight plastic bag and seal it, place it in a withering room at 40°C for 2 hours (7), take out the tea leaves after the heat is over Cool down quickly and disperse. After the leaf temperature drops to room temperature, put it in a knea...
