Problems solved by technology

The tea greening equipment in the prior art has the following defects: 1. During the greening process, the tea leaves are easily attached to the stirring blades in the drum, and it is difficult to clean the tea leaves after the greening is completed, which is inconvenient to use
2. Tea leaves with different sizes have different curing temperatures, but in the existing tea curing equipment, the temperature inside the drum is the same, and all tea leaves are uniformly processed at the same temperature. Smaller tea leaves are prone to excessive water loss, resulting in poor color, shape, and taste of tea
3. In addition to setting up a heating device to heat the tea leaves, the existing tea greening equipment also needs to be equipped with power equipment for frying the tea leaves, which consumes a lot of energy

Embodiment 1

[0017] Such as figure 1 Shown, a kind of tea greening device, a kind of tea greening device, comprises housing 1, and housing 1 is provided with feeding port; Housing 1 is provided with bracket 4 and cylindrical tank body 2, and cylindrical tank body 2 is horizontal Place it on stand 4. The middle part of both sides of cylindrical tank body 2 is welded with rotating shaft 21. The casing 1 is connected with an exhaust port 12 and an air inlet 11, and the air inlet 11 faces the rotating blade 22, and the airflow is passed into the air inlet, and the airflow directly blows on the front of the rotating blade. A hot steam injection device 5 is arranged outside the housing 1, and the hot steam injection device 5 communicates with the air inlet 11, and hot steam is passed into the air inlet 11 to make the rotating blades 22 rotate. Such as figure 2 As shown, the cylindrical tank body 2 is provided with two annular partitions 24, and the two annular partitions 24 divide the cylind...

Embodiment 2

[0020] The difference between the second embodiment and the first embodiment is that the first rotating blade 23 is added on the other side of the rotating shaft 21, and the first air inlet 13 opposite to the first rotating blade 23 is communicated with the casing 1, as image 3 shown. The hot steam is introduced into the casing 1 through the first air inlet 13 , so that the first rotating blade 23 rotates, and the rotating direction of the first rotating blade 23 is the same as that of the rotating blade 22 . When the rotating blade 22 and the first rotating blade 23 rotate in the same direction at the same time, the tea leaves in the cylindrical tank body 2 can be turned over more fully.

Abstract

The invention belongs to the technical field of tea leaf processing, and particularly discloses a tea leaf green-removing device, which comprises a shell, wherein a material hole is formed in the shell; a support and a horizontally placed cylindrical tank body are arranged in the shell; two ends of the cylindrical tank body are rotatably connected to the support through a rotary shaft; a rotor blade is connected to one end of the rotary shaft; an exhaust port and an air inlet are communicated in the shell; the air inlet is opposite to the rotor blade; a hot steam injection device communicated with the air inlet is arranged outside the shell; a plurality of annular clapboards are arranged in the cylindrical tank body, and divide the cylindrical tank body into a plurality of subareas; each subarea is provided with a material door; the material doors are located on one side of the cylindrical tank body. By adopting the tea leaf green-removing device provided by the invention, the different subareas are arranged in the cylindrical tank body, the temperature of each subarea is different, and tea leaves with different sizes are placed in the different subareas, so that the water loss rate of the tea leaves is controlled within a certain range, and a tea leaf green-removing effect is better.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a tea greening device. Background technique [0002] Tea originated in China, the Chinese tea culture is extensive and profound, and the Han people have been drinking tea for thousands of years. Finishing is one of the primary processes of green tea, yellow tea, black tea, oolong tea, pulong tea, and some black tea. The main purpose of greening is to destroy and passivate the oxidase activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make the tea soft, easy to knead and shape, and at the same time emit Green smell, promote the formation of good aroma. [0003] Most of the tea greening equipment in the prior art is a drum type, generally comprising a horizontally arranged drum and a housing outside the drum, and a heater is arranged between the hous...
