Description

Technical Field

[0001] The utility model relates to the technical field of tea drying, in particular to a tea drying machine capable of preventing adhesion. Background Art

[0002] Drying is the last step in making all kinds of tea, and is closely related to the quality of tea. It is one of the most important steps. In addition to drying out the water content of the tea to facilitate storage for long-term drinking, the drying process also helps to further develop the unique color, aroma, taste and shape of the tea on the basis of the previous steps.

[0003] Tea drying is different from drying general objects, and has different functions and requirements. Tea drying is one of the important processes to determine the quality of tea. Existing dryers mostly adopt a box design, which requires constant removal and turning of tea leaves during the drying process, otherwise it will cause uneven drying and seriously affect the quality of tea leaves.

[0004] For example, a tea drying machine disclosed in Chinese patent CN207991164U turns the tea leaves during the drying process by means of a rotating shaft and a tumbling frame, thereby greatly saving labor costs, reducing production processes and production time, and thus greatly increasing the efficiency of tea production; at the same time, the tea leaves are dried by hot air, which greatly improves the uniformity of drying the tea leaves, thereby improving the quality of the tea leaves.

[0005] However, the tea dryer turns the tea leaves in the drying drum by means of a tumbling frame, which may cause the tea leaves in the drying drum to break and affect the quality of the tea leaves.

[0006] For this reason, we urgently need to provide a tea drying machine that can prevent tea leaves from breaking and sticking. Utility Model Content

[0007] The utility model aims to provide a tea drying machine capable of preventing adhesion, so as to solve the problem that the tea drying machine proposed in the above background technology turns the tea leaves in the drying cylinder by means of a tumbling frame, which may cause the tea leaves in the drying cylinder to break and affect the quality of the tea leaves.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tea dryer for preventing adhesion, comprising a ventilation net and side panels, the side panels are fixedly connected to the left and right sides of the ventilation net, a round rod is connected to the middle position of the side panel away from the ventilation net, a bearing is fixedly connected to the middle position of the outer side of the round rod, a support plate is fixedly connected to the outer side of the bearing, a bottom plate is fixedly connected to the lower end of the support plate, a drying mechanism is connected to the side panels and the outer ends of the support plates, the drying mechanism comprises a drying unit and a disassembly unit, the drying unit is arranged at the outer end of the support plate, and the disassembly unit is arranged at the outer end of the side panel.

[0009] The drying unit includes a first motor, a transmission member, a fixed box, a second motor, fan blades and a heating wire. The first motor is fixedly connected to the lower end of the right side of the support plate on the left side of the ventilation net, the transmission member is connected to the outer side of the left end of the round rod on the left side of the ventilation net, the fixed box is fixedly connected to the lower end of the adjacent side of the support plate at the left and right ends of the ventilation net, the second motor is fixedly connected to the lower side of the fixed box at an equal distance, the fan blades are fixedly connected to the outer side of the upper end of the output shaft of the second motor, and the heating wire is horizontally fixedly connected to the inner upper end of the fixed box.

[0010] A further improvement is that the airflow direction blown by the fan blade is from bottom to top. Therefore, after starting the second motor and the electric heating wire, the hot airflow generated by the airflow blown upward by the fan blade passing through the electric heating wire will be blown into the inside of the ventilation net through the ventilation net, drying the tea leaves rolling in the ventilation net, and the rotation of the ventilation net causes the tea leaves in it to roll, which can prevent the tea leaves from breaking during drying, and the airflow blown from bottom to top into the ventilation net will blow the tea leaves attached to the inside of the ventilation net away from the inner surface of the ventilation net, thereby playing the role of preventing adhesion.

[0011] A further improvement is that the disassembly and assembly unit includes a material pipe, a cover, a spring, an insertion rod and a fixing ring, the material pipe is fixedly connected to the lower end of the left side plate on the left side of the ventilation net, the cover is connected to the outer side of the left end of the material pipe, the spring is connected to the inside of the round rod, the insertion rod is fixedly connected to the upper end of the spring, and the fixing ring is fixedly connected to the middle position of the side plate away from the ventilation net.

[0012] A further improvement is that a circular groove is provided at the inner upper end of the round rod near one end of the ventilation net, the lower end of the spring is fixedly connected to the inner bottom end of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove. Therefore, when the spring is elastic, the insertion rod can be driven to slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod.

[0013] A further improvement is that a plug hole is provided in the middle of the upper end of the fixing ring, the outer side of the end of the round rod close to the ventilation net is slidably connected to the inner side of the fixing ring, and the outer side of the upper end of the plug rod is plugged into the middle of the upper end of the fixing ring. Therefore, after the sliding plate at the outer end of the side plate is slid to the outer side of the round rod, the plug rod is pushed up by the spring rebound until the upper end of the plug rod moves up to the plug hole at the upper end of the fixing ring, so that the round rod can be fixed to the inner side of the fixing ring, and the side plate can be fixed to the outer end of the round rod.

[0014] A further improvement is that the outer side of the left end of the material pipe is provided with an external thread, the inner side of the cover is provided with an internal thread, the outer side of the left end of the material pipe is threadedly connected to the inner side of the cover, and a through hole is provided inside the side plate on the left side of the ventilation net at the right end of the material pipe. Thus, by threading the cover to the outer side of the left end of the material pipe, the left end of the material pipe can be closed.

[0015] A further improvement is that a non-slip pad is fixedly connected to the lower side of the bottom plate, so that the rubber pad on the lower side of the bottom plate at the lower end of the support plate contacts the ground, which can make the device more firmly supported on the ground.

[0016] In summary, the present application discloses a tea drying machine that prevents adhesion.

[0017] After the second motor and the heating wire are started, the hot air flow generated by the air flow blown upward by the fan blades passing through the heating wire will be blown into the interior of the ventilation net through the ventilation net, thereby drying the tea leaves tumbling in the ventilation net. In addition, the air flow blown into the ventilation net from bottom to top will blow the tea leaves attached to the inside of the ventilation net away from the inner surface of the ventilation net, thereby preventing adhesion.

[0018] Furthermore, by pressing the insertion rod into the circular groove inside the round rod, the fixing ring can be removed from the outer end of the round rod, so that the ventilation net and the side plate can be removed from the outer end of the round rod together, so that the ventilation net can be easily disassembled and assembled, so that it can be removed for inspection and replacement when the ventilation net is damaged.

[0029] The drying unit includes a first motor 701, a transmission member 702, a fixed box 703, a second motor 704, a fan blade 705 and a heating wire 706. The first motor 701 is fixedly connected to the lower end of the right side of the support plate 5 on the left side of the ventilation net 1, the transmission member 702 is connected to the outer side of the left end of the round rod 3 on the left side of the ventilation net 1, the fixed box 703 is fixedly connected to the lower end of the adjacent side of the support plate 5 at the left and right ends of the ventilation net 1, the second motor 704 is fixedly connected to the lower side of the fixed box 703 at an equidistant distance, the fan blade 705 is fixedly connected to the outer side of the upper end of the output shaft of the second motor 704, and the heating wire 706 is horizontally fixedly connected to the inner upper end of the fixed box 703.
