Dry fermentation device for processing tea

Abstract

The invention provides a dry fermentation device for processing tea. The dry fermentation device comprises a base and a base shell box-shaped body. The dry fermentation device is characterized in that an inner cavity of the base shell box-shaped body is internally provided with a pine inner box-shaped body; the pine inner box-shaped body is in a door frame and pulling door structure formed by splicing a plurality of pine plate strips; a bottom frame of the pine inner box-shaped body is fixedly arranged on a bottom plate of the base shell box-shaped body; a distance is kept between mutually-corresponding wall plates of the pine inner box-shaped body and the base shell box-shaped body; a pine plate framework with a rectangular vertical section is fixedly arranged between a door frame of the pine inner box-shaped body and a door frame of the base shell box-shaped body in a butt joint manner and sealed and fixed connection between the two door frames is carried out; a steam inlet is formed in one side wall of the base shell box-shaped body; the steam inlet is communicated with an exhausting opening of a draught fan by a pipeline; an air inlet of the draught fan is communicated with a steam exhausting opening pipeline of a steam boiler by an air inlet valve; a steam exhausting opening is formed in the other side wall of the base shell box-shaped body and is communicated with a reflowing steam opening pipeline of the steam boiler. According to the dry fermentation device for processing the tea, the steam is used for heating the pine inner box-shaped body to disperse rosin aroma to be immersed into a large contact surface of the tea, and the heating and the aroma entering are uniform.

Description

Technical field: [0001] The invention relates to tea processing, in particular to a dry fermentation device for tea processing. Background technique: [0002] The tea processing process generally includes killing greens, removing stems, kneading, fermenting, and drying. Fermentation can be dry or wet. The applicant adopts dry fermentation in making. [0003] The conventional dry fermentation device is an electric heating type sealed fermentation. The device consists of an iron base shell, a base, an electric heating rod or a Yuba lamp. The base shell is in the shape of a box, on which a door frame is arranged, and a sliding door is hinged inside the door frame, and an electric heating rod or a Yuba lamp is installed on the top wall of the box to provide heat energy. When the tea leaves are fermented, generally the tea leaves are put into the box-shaped body and the sliding door is closed, then energized to heat and keep warm for a period of time. Some manufacturers add ...

AI Technical Summary

Problems solved by technology

[0004] During this fermentation process, the applicant found that the rosin flavor attached to the tea leaves is not uniform. The reason is that the surface area of ​​the rosin block is limited, and it is only laid on the bottom. 1. The pine scent of the tea leaves at the top is weak, or even has no pine scent, which affects the quality of the tea

At the same time, the top of the stacked tea leaves is close to the heating source, the temperature is too high when the heat is too fast, and the bottom of the stack is low-heated, the degree of heating and fermentation is uneven, and the fermentation effect is different.
