Embodiment 1

[0038] A kind of pearl tea production process, comprises the following steps:

[0039] 1) At room temperature, spread the fresh tea leaves for 10 hours;

[0040] 2) Deenzyming: Use a steam degreening machine to deenzyme the fresh tea leaves, and the deenzyming temperature is 90°C;

[0041] 3) Air-cooling: put into the air-cooling device to quickly cool the green leaves and sieve out the tea stems, the temperature drops below 40°C, and the air-cooling time is 80 seconds;

[0042] 4) Dynamic dehydration: first dehydrate with 110°C hot air for 60 seconds, and then use 80°C hot air for dehydration; the 80°C hot air dehydration time is 180 seconds, wherein the water content of the tea leaves is reduced to 50%;

[0043] 5) Dehydration: quickly cool the dehydrated leaves in the air cooling device;

[0044] 6) Kneading and drying: kneading, drying and frying into shape.

Embodiment 2

[0046] A kind of pearl tea production process, comprises the following steps:

[0047] 1) At room temperature, spread the fresh tea leaves for 12 hours;

[0048] 2) Deenzyming: use a steam degreening machine to deenzyme the fresh tea leaves, and the deenzyming temperature is 120°C;

[0049] 3) Air-cooling: put into the air-cooling device to quickly cool the green leaves and sieve out the tea stems, the temperature drops below 40°C, and the air-cooling time is 120 seconds;

[0050] 4) Dynamic dehydration: first dehydrate with 110°C hot air for 80 seconds, and then use 80°C hot air for dehydration; the 80°C hot air dehydration time is 200 seconds, wherein the water content of the tea leaves is reduced to 60%;

[0051] 5) Dehydration: quickly cool the dehydrated leaves in the air cooling device;

[0052] 6) Kneading and drying: kneading, drying and frying into shape.

Embodiment 3

[0054] A kind of pearl tea production process, comprises the following steps:

[0055] 1) At room temperature, spread the fresh tea leaves for 11 hours;

[0056] 2) Finishing: Use a steam curing machine to complete the greening of the fresh tea leaves at a temperature of 105°C;

[0057] 3) Air-cooling: put into the air-cooling device to quickly cool the green leaves and sieve out the tea stems, the temperature drops below 40°C, and the air-cooling time is 100 seconds;

[0058] 4) Dynamic dehydration: first dehydrate with 110°C hot air for 70 seconds, and then use 80°C hot air for dehydration; the 80°C hot air dehydration time is 190 seconds, wherein the water content of the tea leaves is reduced to 55%;

[0059] 5) Dehydration: quickly cool the dehydrated leaves in the air cooling device;

[0060] 6) Kneading and drying: kneading, drying and frying into shape.

Abstract

The invention discloses a gunpowder tea production process which comprises the following steps: spreading fresh tea leaves for 10-12 hours at room temperature; carrying out fixation on the fresh tea leaves by adopting a steam fixation machine, wherein the fixation temperature is 90-120 DEG C; the tea leaves are put into an air cooling device to be rapidly cooled, tea stems are screened out, the temperature is reduced to 40 DEG C or below, and the air cooling time is 80-120 seconds; dehydrating with hot air at 110 DEG C for 60-80 seconds, and then dehydrating with hot air at 80 DEG C; quickly cooling the dehydrated leaves in an air cooling device; and rolling, drying, stir-frying and forming. By improving the fixation technology, dynamic dehydration and air cooling equipment are used for rapid cooling and screening off fallen tea stems, the prepared steamed gunpowder tea is green and moist in color and free of smoke and scorch gas, and the problems that the fixation of the gunpowder tea mostly adopts a traditional roller and pot type contact heat transfer fixation mode and the like, and due to the fact that the mode is uneven in fixation, tea leaves are prone to edge scorch, and the fixation efficiency is poor are solved. The color and luster are greatly damaged, and more black tea stems exist.

Description

technical field [0001] The invention relates to the production field of tea making technology, in particular to a pearl tea production technology. Background technique [0002] At present, pearl tea, also known as round fried green tea, is one of the unique types of green tea in my country. Its shape is round, compact and smooth, in the shape of granules, just like round beads; its green color, high aroma, strong flavor, and long-lasting foam resistance make it well-known both at home and abroad, and it is one of the main export green teas in my country. Pearl tea processing is mainly divided into three processes: greening, rolling, and drying and frying. Drying is divided into four steps: two greens, small pots, double pots, and large pots. Among them, greening is the most critical process for forming the quality of pearl tea. At present, most of the greening of pearl tea adopts the traditional roller, pot and other contact heat transfer methods. Due to the uneven drying, ...
