Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea withering machine for evenly drying tea leaves. Background Art

[0002] Withering is an additional step in the tea processing technology to improve the quality of tea. Withering is to spread the freshly picked green tea leaves according to a certain thickness to evaporate the moisture on the surface of the green tea leaves, causing the green tea leaves to wilt, so as to ensure the quality of the tea leaves in the subsequent processing; at the same time, withering can also make the grassy smell of the green tea leaves disappear and produce a fresh fragrance, and promote the conversion of some ester catechins in the tea leaves into non-ester catechins, thereby reducing the bitterness and making the prepared tea products mellow and not bitter. Traditional tea withering uses natural air-drying of the green tea leaves, but the moisture on the surface of the green tea leaves is lost, resulting in a longer withering cycle and uneven withering, which affects the overall quality of the tea leaves.

[0003] Nowadays, tea is usually withered in a withering machine, but the existing withering machines are generally used to evenly spread the tea leaves manually, and manual laying often has limitations, and the uniform effect on the tea leaves is not good, and it is easy for some parts to be thick and some parts to be thin, resulting in uneven withering effect on the tea leaves. There are certain requirements for thickness during withering, and it cannot be too thick, and it is difficult to control the thickness of the laying manually. Utility Model Content

[0004] The utility model aims to provide a tea withering machine for evenly spreading tea leaves to solve the problem that the existing tea withering machines cannot evenly spread tea leaves and the manual laying effect is poor.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A tea withering machine for evenly drying, comprising a box, a door panel hinged on the box and used for opening and closing the box, a fluorescent lamp arranged on the top inner wall of the box, a fan arranged on the box, and further comprising: a horizontal plate arranged between the inner walls on both sides of the box, a placement box placed on the horizontal plate, a main shaft vertically penetrating the middle of the placement box and cooperating with the horizontal plate for rotation, a driving mechanism arranged at the bottom of the horizontal plate and used for driving the main shaft to rotate, and a spreading mechanism arranged on the main shaft and used for spreading tea leaves in the placement box evenly, wherein the width of the horizontal plate is smaller than the width of the box;

[0007] The spreading mechanism includes a slide cylinder detachably connected to the main shaft, a cross bar arranged on the outside of the slide cylinder, a vertical bar arranged at the bottom of the cross bar, a connecting plate arranged at the end of the vertical bar away from the cross bar and extending into the placement box, and a toothed comb evenly spaced at the bottom of the connecting plate, the bottom of the toothed comb contacts the bottom inner wall of the placement box.

[0008] Furthermore, the above-mentioned spreading mechanism also includes a baffle plate parallel to the connecting plate, and screw rods respectively passing through the top two sides of the baffle plate, and vertical sliding grooves corresponding to the screw rods are respectively opened on both sides of the connecting plate, and the screw rods pass through the vertical sliding grooves and are locked by nuts.

[0009] Furthermore, the side wall of the slide cylinder is threadedly connected with a screw, and the screw passes through the side wall of the slide cylinder and is threadedly connected with the main shaft.

[0010] Furthermore, the spreading mechanism also includes a telescopic rod disposed on one side of the connecting plate and close to the inner wall of the placement box, and the inner wall of the placement box is provided with a hemispherical block corresponding to the telescopic end of the telescopic rod.

[0011] Furthermore, the telescopic rod includes an outer tube arranged on one side of the connecting plate, an inner rod slidingly matched with the outer tube and corresponding to the hemispherical block, and a spring connected between the inner rod and the inner bottom wall of the outer tube, and the end of the inner rod away from the outer tube is an arc structure.

[0012] Furthermore, the placement box includes a disc, an annular side plate arranged in an annular shape on the top outer edge of the disc, and a fixed cylinder embedded in the middle of the disc. The main shaft passes through the fixed cylinder and the cross plate in sequence and is connected to the output shaft of the driving mechanism. The hemispherical block is arranged on the inner wall of the annular side plate.

[0013] Furthermore, the driving mechanism includes a U-shaped frame arranged at the bottom of the transverse plate, a motor arranged at the bottom of the U-shaped frame, and a coupling located inside the U-shaped frame, and the output shaft of the motor passes through the U-shaped frame and is connected to the main shaft through the coupling.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model is provided with a spreading mechanism, and fresh tea leaves are laid in a placement box and can be irradiated by a fluorescent lamp. A fan is used to ventilate the interior of the box. The main shaft is driven to rotate by the driving mechanism, and the main shaft drives the toothed comb in the spreading mechanism to rotate. The toothed comb contacts the inner bottom wall of the placement box, and the fresh tea leaves in the placement box can be uniformly stirred when the toothed comb rotates, and can be evenly spread under the action of the fluorescent lamp; the position of the baffle on the connecting plate can be adjusted by loosening or tightening the screw, so as to determine the thickness of the laid tea leaves. For tea leaves higher than the bottom of the baffle, the baffle can be rotated when driven by the spreading mechanism to push the tea leaves higher than the bottom of the baffle, so as to make the thickness of the tea leaves consistent and enable the tea leaves to wither evenly.

[0016] 2. The utility model arranges a telescopic rod on the side wall of the connecting plate, and arranges a corresponding hemispherical block in the placement box. When the driving mechanism drives the spreading mechanism to rotate, the connecting plate drives the telescopic rod to rotate. When the inner rod in the telescopic rod contacts the hemispherical block, an impact force is generated. At the same time, under the action of the impact force, the inner rod compresses the spring and slides into the inner part of the outer tube, which drives the connecting plate to shake, so that the tea leaves adhered to the toothed comb and the baffle can be shaken off, which can prevent the tea leaves from adhering to the baffle and affecting the spreading effect. The structure is simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
