Description

Technical Field

[0001] The utility model relates to the technical field of tea withering, in particular to a uniform spreading feeding device for a tea withering production line. Background Art

[0002] Because the newly picked buds and leaves have a high water content (75-80%), the cells are saturated with water, and the buds and leaves are fresh and swollen. During the withering process, the buds and leaves lose a lot of water, which greatly reduces their elasticity, hardness, weight and volume. This is the so-called physical withering. Due to the large amount of water dissipated from the cells, the semi-permeability of the cell membrane disappears, causing the components that were originally separated by the cell membrane to penetrate into the cytoplasm and have the opportunity to contact each other. Through the catalytic action of enzymes, complex chemical changes occur, forming the unique aroma, taste and water color components or their precursors of tea. This is the so-called biochemical withering. During the withering process of tea leaves, the tea leaves need to be placed evenly to make the heating more even. Increase the speed of water dissipation.

[0003] The Chinese utility model patent (CN221139763U) relates to the technical field of tea processing. It includes a conveying mechanism, a hopper, a feeding pipe and a fan. The upper end of the hopper is connected to the conveying mechanism, and the lower end of the hopper is connected to the feeding pipe. The fan is arranged at one end of the feeding pipe, and the other end of the feeding pipe is provided with a feeding port for feeding the tea machine. The tea feeding device disclosed in the utility model conveys tea leaves to the hopper through the conveying mechanism, and the tea leaves fall into the feeding pipe from the lower end of the hopper, and then the tea leaves in the pipe are blown into the tea machine through the feeding port of the feeding pipe by the fan, so that the tea leaves can be fed, and the lifting height of the elevator can be reduced. There is no need to set a special receiving device on the tea machine, which can reduce the space occupied, save equipment costs, and improve the efficiency of tea feeding and discharging.

[0004] The above patent has the effect of reducing space occupation, saving equipment costs, and improving the efficiency of tea loading and unloading. However, it cannot spread the tea evenly during use, and it is even more impossible to control the thickness of the spread (the stacking thickness and duration vary depending on the degree of withering and weather conditions. Generally, in low-temperature and dry weather, the thickness of the leaves is 20 to 30 cm, and it takes 3 to 4 hours; in hot and humid southerly days, the thickness of the leaves is about 15 to 20 cm, and it takes about 2 to 3 hours.) The tea leaves are heated unevenly during the processing, affecting production efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a uniform spreading feeding device for a tea withering production line, which can evenly spread the tea on a conveyor belt and adjust the thickness of the evenly spread tea.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: providing a tea withering production line uniformly spreading feeding equipment, comprising a conveyor belt and a uniform spreader arranged at one end of the conveyor belt; the uniform spreader comprises a cylindrical shell and a rotating shaft coaxial with the shell, and rectangular blades are evenly arranged on the rotating shaft, and the edges of the blades are against the inner wall of the shell;

[0007] It also includes a plurality of cylinders with different diameters, one of which is sleeved on the rotating shaft, and is provided with an avoidance groove adapted to the leaves, and the outer surface of the cylinder cooperates with two adjacent leaves to form a tea accommodating cavity;

[0008] It also includes a feed port and a discharge port communicated with the shell; and a driving device, which controls the rotation of the rotating shaft.

[0009] Furthermore, a side of the housing away from the driving device is detachable.

[0010] Furthermore, the driving device is a variable frequency speed regulating motor.

[0011] Furthermore, the extension of the feed port is inclined and expanded outwards.

[0012] Furthermore, it also includes a scale, which is vertically arranged on the side of the conveyor belt.

[0013] Furthermore, it also includes a scraper plate, which is horizontally arranged above the conveyor belt and is controlled to rise and fall by a screw rod.

[0014] The beneficial effect of the utility model is that a sufficient amount of tea leaves are poured into the feed port, and the tea leaves enter the tea holding chamber from the feed port. The driving device drives the rotating shaft to rotate at a constant speed, and the tea leaves are discharged from the discharge port and fall onto the conveyor belt. Since the capacity of the tea holding chamber is equal and the drop interval is the same, the tea leaves can be evenly spread. When different tea leaves are needed to be spread, because the present application includes a plurality of cylinders with different diameters, the cylinders with corresponding diameters can be replaced as needed to change the capacity of the tea holding chamber, so as to change the thickness of the tea leaves.

[0033] Furthermore, it also includes a scraper plate 4, which is horizontally arranged above the conveyor belt 1, and the scraper plate 4 is controlled to rise and fall by a screw rod.

[0034] As can be seen from the above description, the scraper plate 4 can further scrape the tea leaves on the conveyor belt 1. When the thickness of the tea leaves is different, the height of the scraper plate 4 needs to be controlled.

[0035] Embodiment 1:

[0036] Application scenario: During the withering process of tea leaves, the tea leaves need to be placed evenly to make the heating more even. Increase the speed of water dissipation. Since the thickness and duration of the pile vary depending on the degree of withering and weather conditions, the thickness of the piled leaves is generally 20 to 30 cm in low temperature and dry weather, and it takes 3 to 4 hours; the thickness of the piled leaves is about 15 to 20 cm in hot and humid southerly windy days, and it takes about 2 to 3 hours, so the thickness of the pile also needs to be controlled.

[0037] like Figure 1-3 , a tea withering production line evenly spreading feeding equipment, comprising a conveyor belt 1 and an evenly spreading device 2 arranged at one end of the conveyor belt 1; the evenly spreading device 2 comprises a cylindrical shell 21 and a rotating shaft 22 coaxial with the shell 21, and rectangular blades 23 are evenly arranged on the rotating shaft 22, and the edges of the blades 23 are against the inner wall of the shell 21;

[0038] It also includes a plurality of cylinders 24 of different diameters, one of the cylinders 24 is sleeved on the rotating shaft 22, and the cylinder 24 is provided with an avoidance groove 241 adapted to the blades 23, and the outer surface of the cylinder 24 cooperates with two adjacent blades 23 to form a tea accommodating cavity 25 (the width of the spreader is close to the width of the conveyor belt 1, and the leaf accommodating cavity is a long strip and can be approximately regarded as a line. When working, the falling material is composed of lines to form a surface to achieve a flattening effect).

[0039] It also includes a feed port 25 and a discharge port 26 communicated with the housing 21 (the feed port 25 and the discharge port 26 are eccentrically arranged with the housing 21, and the feed port 25 and the discharge port 26 are not colinear); it also includes a driving device 27, and the driving device 27 controls the rotation of the rotating shaft 22.
