Background technique

China has a long history of tea making. Since the discovery of wild tea trees, it has undergone complex changes from raw boiled soup to tea cakes and loose tea, from green tea to various types of tea, and from hand-made tea to mechanized tea-making. The quality characteristics of various teas are formed. In addition to the influence of tea tree varieties and fresh leaf raw materials, processing conditions and techniques are important determinants.

The tea making process mainly includes the steps of picking, fixing, rolling and drying, among which fixing is one of the most critical processes in the tea making process, which determines the aroma and taste of the finished tea. Greening is the use of high temperature to treat fresh tea leaves, high temperature kills the catalytic enzymes in the green leaves, inactivates the enzymes, keeps the leaves green, and uses thermal chemical reactions to eliminate green smell, bitterness, and astringency in the leaves, and transform them into tea with a floral aroma. Kill the green leaves. During the greening operation, the principle of throwing high, spreading wide, and scooping up should be followed, so that the tea leaves are heated evenly, the water evaporates quickly, and red leaves are avoided from scorching.

At present, most of the existing mechanical equipment for greening is to pour the tea leaves into the horizontally rotating cylinder, and use the rotation of the cylinder to turn the tea leaves to make the heat evenly. However, the ability of the rotation of the cylinder to turn the tea leaves is limited, and the local temperature is too high. Burnt problem seriously affects the quality of tea.

Preferably, the outer cylinder and the drum are in a set-up structure, and there is a heat exchange chamber between them, and the V-shaped section of the drum is evenly distributed with vent holes penetrating the inside of the drum and the heat exchange chamber.

Preferably, the inner wall of the drum is provided with a screw propulsion mechanism correspondingly from both ends to the middle.

Preferably, the spiral propulsion mechanism is a spiral baffle perpendicular to the inner wall of the drum, and the baffle is arranged in a continuous spiral or discontinuous spiral.

Preferably, the top of the V-shaped section of the drum is provided with a drum outlet, and the drum outlet corresponds to the outlet on the outer cylinder.

Preferably, the external V-shaped included angle of the V-shaped section of the drum is 90-150 degrees.

Preferably, the diameter of the outer cylinder corresponding to the V-shaped section of the drum is larger than the diameter of the corresponding straight section, and the heating element is arranged in the outer cylinder corresponding to the V-shaped section of the drum.

Preferably, the power part includes a motor, a pulley arranged at one end of the drum, and a pulley arranged at the other end of the drum and assembled with the outer cylinder, the motor connects the pulley with a belt and drives the drum to rotate under the cooperation of the pulley .

Preferably, the feed hopper is arranged at one end of the drum, and the other end of the drum is provided with a vent.

Preferably, the outer cylinder is made of thermal insulation material rock wool thermal insulation felt or glass wool.

Advantages and beneficial effects of the utility model:

The utility model adopts a drum with a V-shaped section in the middle, so that the tea leaves can be thrown up and down with the V-shaped section while turning with the drum. Under the action of the machine, it moves to the V-shaped section for concentrated heating, and the turning range of the tea leaves in the V-shaped section increases, so that the tea leaves are heated evenly and prevent the tea leaves from being scorched due to excessive local temperature. The utility model is also provided with through holes in the V-shaped section of the drum, which facilitates heat transfer to the tea leaves, reduces heat loss, ensures uniform temperature, and has significantly higher energy utilization than traditional methods.
