Problems solved by technology

The processing of existing yellow tea is mainly manual and simple machine processing, and the manual use of wok is the processing equipment, and the frying master completes the greening and drying based on experience. The technical requirements for the frying master are relatively high, and the processing efficiency is low, so it cannot be used on a large scale. Production and processing
Simple machining is an automated processing method that overcomes manual deficiencies, but because it completes all the processes in the flat tea frying machine at one time, the processed tea leaves are astringent, and tea leaves of different sizes cannot be separated. The processed tea leaves are of different sizes, mixed together, and the processing quality is poor

Abstract

The present invention relates to a processing method of yellow tea. The method comprises the following steps of picking, enzyme deactivating, heaping for yellowing, air-spreading, rolling, drying and packing. The enzyme deactivating temperature is 320-340 DEG C, every 5 kg of tea is subjected to treatment of heaping for yellowing, every treatment is controlled at 100-135 DEG C, every heaping for yellowing is conducted for 30-60 min, the temperature of the air-spreading is controlled at 18-20 DEG C, and the air (wind) speed is controlled at 0.5-1.5 m / s to achieve the best effect. The yellow tea processed by the processing method of the yellow tea is compact in appearances, fresh and bright in color and luster, pure in aroma and mellow in tastes.

Description

technical field [0001] The invention relates to yellow tea, in particular to a method for processing yellow tea. Background technique [0002] Yellow tea is a special product of our country. It is retting tea. During the retting process, a large amount of digestive enzymes will be produced, which is most beneficial to the spleen and stomach. Indigestion, loss of appetite, laziness and obesity can all be drunk and melted. Yellow tea is rich in tea polyphenols, amino acids, soluble sugar, vitamins and other rich nutrients, which have obvious effects on the prevention and treatment of esophageal cancer. In addition, more than 85% of the natural substances in the fresh leaves of yellow tea are retained, and these substances have special effects on cancer prevention, anti-cancer, sterilization, and anti-inflammation, which are beyond the reach of other teas. In particular, yellow tea contains γ-aminobutyric acid. Numerous studies at home and abroad have shown that γ-aminobutyric...
