Problems solved by technology

[0003] The taste of green tea is the best among the four kinds of tea. The processing of green tea includes picking, greening, killing, cooling, rolling, dehumidification, drying, roasting and other steps. Green tea is divided into spring tea and summer tea. The processing of tea requires fine processing, and the roasting step is a key step, which can easily affect the quality of green tea. However, most of the existing roasting steps use a fire to roast and stir fry automatically through an automatic frying pan. It is easy to cause a part of the tea to be fried, which will affect the quality of the tea

Abstract

The invention relates to the filed of tea producing and processing, and especially relates to a fine machining technology for green tea. The fine machining technology for the green tea comprises the following steps: carrying out picking, tedding fresh tea leaves, deactivating enzymes, carrying out cooling, carrying out rolling, removing dampness, carrying out air-drying, carrying out baking and carrying out packaging. The invention further relates to a fine machining system for green tea. The fine machining system for the green tea comprises a tea-leaf tedding device; the tea-leaf tedding device is connected to an enzyme deactivating device; the enzyme deactivating device is connected to a cooling device; the cooling device is connected to a rolling device; the rolling device is connected to a dampness removing device; the dampness removing device is connected to an air-drying device; the air-drying device is connected to a baking device; the baking device is connected to a second-rolling device; the second-rolling device is connected to a second-baking device; and the second-baking device is connected to a packaging device. Purpose of the invention is to provide a fine machining technology and a machining system for the green tea. The green tea is baked by utilizing hot air and artificial stir-frying, so that temperature for stir-frying can be very well controlled so as to prevent the tea leaves from being burnt; at the same time, tea trimming and tipping can be carried out during artificial stir-frying, so that qualities of the green tea are further improved.

Description

technical field [0001] The invention relates to the field of tea production and processing, in particular to a green tea finishing process and processing system. Background technique [0002] China is a big country with thousands of years of tea culture. It has formed a variety of tea families, mainly including black tea, green tea, black tea and white tea. These four kinds of tea are widely loved by people. [0003] The taste of green tea is the best among the four kinds of tea. The processing of green tea includes picking, greening, killing, cooling, rolling, dehumidification, drying, roasting and other steps. Green tea is divided into spring tea and summer tea. The processing of tea requires fine processing, and the roasting step is a key step, which can easily affect the quality of green tea. However, most of the existing roasting steps use a fire to roast and stir fry automatically through an automatic frying pan. It is easy for some tea leaves to be fried, which will ...
