Problems solved by technology

[0002] The traditional granule tea has a fast kneading speed, which is easy to break and break during the processing of tea leaves, and the sliver rate is low, which is not conducive to the formation of tea leaves
Traditional dehydration adopts drying or frying, and the dehydration time is long, which affects the color of tea leaves
The traditional shaping technology requires high mastery, and it is easy to appear that the tea leaves are less green in color and form a bonded leaf on the wall of the shaping pot, resulting in a burnt smell.

Embodiment 1

[0013] A slow-kneading and quick-release forming method for tea leaves, comprising the following steps:

[0014] (1) Slow kneading: Fill the rehydrated leaves into the kneading barrel of the 6CR-255 kneading machine, slightly press the rehydrated leaves with your hands, and the amount of leaves thrown is slightly more than that of other green teas. The rotation speed of the kneading machine is 35r / min, the whole kneading time is 25min, and the halfway is lightly pressed for 2min; the cell fragmentation rate is 32%, basically all of them are formed into strands, and the crushing rate is about 3.38%.

[0015] (2) Dehydration: use hot air drum to dehydrate, the temperature is 73°C-80°C, the leaf temperature is 57°C-60°C, and the time is 1.5min. The water content is 44%, dark green, the bud tips are slightly visible, and the fragrance is revealed. Prickly feel, no balls when pinched, no sticky feel;

Abstract

The invention discloses a slow-rolling and quick-dehydrating tea forming method, comprising the following steps: filling the conditioned leaves in a rolling barrel of a rolling machine to be rolled; dehydrating the leaves until the water content is 40-45%; and shaping the leaves three times: carrying out first shaping under the following conditions: pot bottom wall temperature of 190-220 DEG C, leaf temperature of 40-50 DEG C, stuffiness, big arc, speed of 100-110r / min, leaf weight of 2.5-3kg and time of 26-37min; carrying out first pot merging and second shaping under the following conditions: pot bottom wall temperature of 155-185 DEG C, leaf temperature of 45-55 DEG C, stuffiness, big arc, speed of 100-110r / min, leaf weight of 7.5-8.0kg and time of 34-43min; and carrying out second pot merging and third shaping under the following conditions: pot bottom wall temperature of 180-220 DEG C, leaf temperature of 60-70 DEG C, ventilation, small arc, speed of 55-60r / min, leaf weight of 9-10kg and time of 35-45min. The method can fully ensure the color and aroma of the tea, reduce broken tea, ensure the tea to be easy to form strips and ensure the tea particles to be rolled more tightly and uniformly.

Description

technical field [0001] The invention relates to a tea processing method, in particular to a tea forming method. Background technique [0002] The traditional granule tea has a fast kneading speed, which is easy to break and break during the tea processing process, and the sliver rate is low, which is not conducive to tea shaping. Traditional dehydration uses drying or frying, and the dehydration time is long, which affects the color of the tea. The traditional shaping technology requires high mastery, and it is easy to have the phenomenon that the tea leaves are less green in color and form bonded leaves on the wall of the shaping pot, resulting in a burnt smell. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned shortcomings and provide a method of slowly kneading and quickly releasing the tea leaves, which can fully ensure the color and aroma of the tea leaves, reduce the generation of broken powder, make the tea leave...
