Tea leaf fermentation box

Abstract

The invention relates to a tea leaf fermentation box. The tea leaf fermentation box comprises a box body and a steam pipeline system, wherein the box body is of a semi-closed structure with three sidepanels and a bottom plate; the bottom plate is higher than the ground and is provided with a drainage device; and the steam pipeline system comprises a conveying pipe and spray pipes, wherein spray holes are formed in the spray pipes, and each spray pipe penetrates through the corresponding through hole in the bottom plate and is exposed above the bottom plate. According to the fermentation box provided by the invention, the spray pipes are arranged in the box body, so that steam can be in contact with tea leaves on upper and lower layers at the same time without passing through the tea leaves on the lower layer and then being in contact with tea leaves on the upper layer, the tea leaves are more uniform during cooking, and the fermentation box is simple in structure and convenient to mount and use, and the bottom plate is about 10cm higher than the ground. The drainage device is arranged on the bottom plate, so that water on the tea leaves on the bottom layer can be drained in time,and the phenomenon of uneven tea leaf humidity is avoided.

Description

technical field [0001] The invention relates to the technical field of tea production equipment, in particular to a tea fermentation box. Background technique [0002] The production and processing technology of black tea generally includes four processes of killing greens, rolling, stacking fermentation and drying; among them, stacking fermentation is one of the most critical processing steps. In the prior art, it is generally completed by special equipment. For example, CN 105076516 A discloses a tea steamer, which includes a steam cylinder, a material cylinder, and a steam plate fixed between the steam cylinder and the material cylinder. The steam plate A plurality of air guide holes are opened on the top of the cylinder, and the steam cylinder is a funnel-shaped cylinder body. On the side of the cylinder body, there is an air inlet pipe connected with the inside of the cylinder body. At the lower end of the cylinder body, there is a A drain pipe, the air intake pipe is ...

AI Technical Summary

Problems solved by technology

However, when the device is in use, the steam flows upward from the bottom, so that the steam must first flow through the lower layer of tea leaves before it can contact the upper layer of tea leaves, so that the time of contacting the steam between the upper layer of tea leaves and the lower layer of tea leaves is different, resulting in uneven cooking of tea leaves and affecting the quality of fermentation
