Tea leaf processing technique

Abstract

The invention discloses a tea leaf processing technique, comprising the following steps: selecting and picking fresh, tender and strong three leaves with one bud; spreading the picked tea leaves uniformly on a bamboo sieve for cooling; standing the cooled tea leaves indoors; pouring the stood tea leaves into a bamboo rocking machine for rocking; killing the rocked tea leaves in a killing pot; rolling the killed tea leaves in a rolling machine, lightly rolling for 10-12 minutes, heavily rolling for 5-8 minutes, and then lightly rolling again for 18-20 minutes; shaping the rolled tea leaves in a tea leaf shaper; drying the shaped tea leaves in a dryer; disinfecting the dried tea leaves; and packaging the tea leaves in a vacuum condition. According to the tea leaf processing technique, the killing environment is scientifically and reasonably improved, the activity of oxidase in fresh tea leaves is better destroyed and passivated, enzymatic oxidation of tea polyphenols and the like in fresh leaves are inhibited, and partial moisture in fresh leaves is evaporated, so the tea leaves are softened and convenient for rolling and shaping, formation of good aroma is promoted, and the processing quality of tea leaves is improved.
