Black tea autofermentation machine

Abstract

A black tea autofermentation machine relates to the technical field of tea processing equipment and especially belongs to an autofermentation machine applied in black tea processing and production. The black tea autofermentation machine comprises a machine body and a control device (4). A rotation cage is arranged inside the machine body. A casing is a composite-layer structure and comprises an outer shell, a heat-insulation layer (22) and an inner shell (8) which are arranged from outside to inside. A cavity is formed between the heat-insulation layer and the inner shell. A fermentation auxiliary device and a fragrance extraction auxiliary device are disposed inside the machine body. A CPU input end of the control device is connected with a power supply module, a temperature sensor (13), a humidity sensor (14) and a set value input device. A CPU output end is connected with a display, a built-in fan motor-drive circuit, an external blower fan drive circuit, a rotation cage motor-drive circuit, an electric heater drive circuit and a steam generator. The black tea autofermentation machine operates under the conditions of fixed temperature value, humidity value and time value, has a compact structure, has high automation degree, is convenient and efficient, and has positive effects of reasonable design and strong controllability.

Description

technical field [0001] The invention relates to the technical field of tea processing equipment, in particular to an automatic fermentation machine used in black tea processing and production. Background technique [0002] Black tea is a fully fermented tea. China is the birthplace of black tea production. Black tea was invented as far back as the end of the 16th century. In recent years, with the continuous development of global economic integration, changes in people's diet and consumption structure, the domestic tea consumption market has become increasingly diversified, and the "black tea craze" has gradually emerged. Especially the unique health-care function that black tea produces because of its special processing technology, is more and more subject to the favor of consumers in general. According to statistics, the national output of black tea in 2010 was 90,000 tons, an increase of 20% compared with 2009, and the development speed was significantly higher than that...

AI Technical Summary

Problems solved by technology

However, in the production process of black tea, the processes of withering, rolling, fermentation, drying and aromatization are completed by special equipment and facilities. For small processing plants, the production input is unbearable, and the product cost is also high. Moreover, if fermentation and uneven drying, it is easy to cause sticky pan burnt, water stuffiness and other phenomena, which will seriously affect the quality of tea
