Tea leaf fixation device capable of performing high-efficient overturning on tea leaves

Abstract

The invention discloses a tea leaf fixation device capable of performing high-efficient overturning on tea leaves. The tea leaf fixation device comprises a housing, a motor, a rotating shaft, a gear and a roller, wherein the motor is fixedly connected to the lower end of the housing; one end of the rotating shaft is fixedly connected to the output end of the motor; the gear fixedly sleeves the rotating shaft; one end of the gear penetrates through a sliding hole formed in the lower end of the housing and reaches in the housing; heated air currents are circulated and reused, so that during secondary heating, heating can be quicker, and the required temperature can be quickly achieved, and the effect of saving energy resources is achieved; during fixation of tea leaves, stirring blades in the roller are used for continuously overturning the tea leaves, and then the acting force of the air currents is combined, so that required fixation effects of the tea leaves can be quicker and betterachieved; and besides, under the cooperation of an overturning device, tea leaves are better overturned, and the heating is more uniform.

Description

technical field [0001] The invention relates to the technical field of tea production equipment, in particular to a high-efficiency flipping tea greening device. Background technique [0002] Tea greening is to destroy and passivate the oxidase activity in fresh tea leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make tea soft, easy to knead and shape, and emit green odor at the same time Taste, a tea-making step that promotes the formation of a good aroma, and finishing is a key process for the formation of the shape and quality of green tea. [0003] And in the existing de-enzyming device, the drum de-enzyming device is multi-purpose, and the de-enzyming function of the cylinder can be used as functions such as tea fresh leaves de-enzyming, rolling and frying. Its structure includes a frame, a transmission mechanism, a drum, a feed hopper on the left side, a heating device under t...

AI Technical Summary

Problems solved by technology

A leaf lifter is installed at the leaf outlet to force air cooling of the tea after finishing, but the effect of turning the tea leaves with the existing drum fixing device is not good, which may easily lead to uneven heating of the tea and affect the finishing effect of the tea.

[0004] The Chinese document is CN207075489U, a new type of high-efficiency flipping tea greening device. During the greening process, the electric heating plate under the greening cylinder supplies heat, and the heat is transferred to the tea leaves through the heat conduction plate, and the tea leaves are greened. At the same time, the stirring motor drives the spiral blades to The tea leaves are conveyed slowly, and the stirring teeth stir and turn the tea leaves while conveying, so that the tea leaves are fully heated, which improves the effect and efficiency of greening, and a temperature sensor and controller are installed. During the greening process, the temperature signal is fed back to the controller through the temperature sensor , the operator can adjust the heating temperature of the electric heating plate through the adjustment button according to the feedback temperature and the appropriate temperature of the tea leaves, so as to avoid the tea burnt due to the high temperature, or the incomplete completion due to the low temperature. Stirring and finishing combined with finishing can not only improve the quality of tea leaves, but also complete them thoroughly. However, when stirring and turning, only through spiral turning, the tea leaves will naturally gather together, and the effect is not good.

[0005] The Chinese literature is CN206005796U, a kind of drum-type tea fixing machine that is convenient for discharging, a kind of drum-type tea fixing machine that is convenient for discharging, because the cross bar between the two table legs is convenient to increase the overall stability of the fixing machine, Due to the four stoves, the use of the stove can be determined according to the temperature requirements of the tea leaves, which is conducive to the rapid temperature rise in the cavity. Due to the telescopic hydraulic rod in the groove, when the tea leaves are finished, the telescopic hydraulic rod is controlled to rise. One side of the frame rises to release the finished tea leaves. Due to the universal rollers at the lower end of the table legs, the fixer can be moved to the desired position, which greatly reduces the labor of people to carry tea leaves back and forth. When the tea leaves are rotated and turned, the stirring effect is poor and it is easy to cause accumulation
