Green tea processing and preparation process

Abstract

The invention discloses a green tea processing and preparation process. The green tea processing and preparation process includes the following steps: picked tea leaves are washed and then placed on abamboo stand for air-drying, the tea leaves after air-drying are subjected to enzyme deactivation by using a fixation machine, wherein the enzyme deactivation temperature is 265-275 DEG C, and the enzyme deactivation time is 8-12 minutes; the tea leaves after enzyme deactivation are put into a twisting machine for twisting, heavily kneaded for 3-5 minutes, gently kneaded for 5-7 minutes, heavilykneaded for 8-10 minutes and finally gently kneaded for 6-8 minutes, and a cell breakage rate is 56-58%; the twisted tea leaves are dried by using gross fire to the water content of 12-22%; the tea leaves after drying and cooling are placed in a bottle-type fry-drying machine; and the fried and dried tea leaves are screened, vacuumized and packaged. According to the green tea processing and preparation process, the tea leaves are subjected to enzyme deactivation completely, an exhaust process of the enzyme deactivation process is increased, the occurrence of stuffiness in the enzyme deactivation process is effectively avoided, the quality of green tea processing is improved, and the quality of green tea is improved. The processed green tea is full of aroma which is long-lasting.

Description

technical field [0001] The invention relates to the technical field of green tea production, in particular to a green tea processing and preparation process.

Problems solved by technology

At present, there is no reasonable control of green tea processing during green tea processing, and there is often sullen air in green tea, which makes the green tea not complete, and even causes tea deterioration in severe cases, which affects the normal processing of green tea and affects the quality of green tea.

Moreover, there is no scientific drying, so that the processed tea leaves have a weak taste, no fragrance, dry color, and poor quality, which affects the quality of green tea.
