Description

Technical Field

[0001] This utility model relates to the field of tea technology, and in particular to a screening and drying device for tea processing. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Tea leaves contain catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. In the tea production process, tea leaves need to be screened and dried.

[0003] A search revealed a Chinese patent (application number "202320784921.6") disclosing a "screening and drying device for tea processing." This device includes a base, the top of which is connected to a fixed outer cylinder. The fixed outer cylinder contains a rotating material cylinder. A support frame a is fixedly installed on the top of the fixed outer cylinder, and the bottom of support frame a is connected to a hot air blower. A spiral stirring block is provided on the inner wall of the rotating material cylinder. The bottom of the rotating material cylinder is connected to a servo motor a, which is fixed to a support frame b. The support frame b is installed at the bottom of the fixed outer cylinder, and the side of the fixed outer cylinder is connected to the servo motor b. However, this device cannot screen the tea leaves during use, requiring the dried tea leaves to be screened again. Screening during this process easily causes the tea leaves to break, resulting in low practicality. Utility Model Content

[0004] This utility model provides a screening and drying device for tea processing, which solves the problem that the screening and drying device proposed in the prior art cannot screen tea leaves, resulting in the need for the dried tea leaves to be screened again, which easily causes the tea leaves to break during screening and has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tea processing screening and drying device includes a base. Two tilting mechanisms are provided on the top of the base. Each tilting mechanism includes a side plate fixed to the outer wall of the top of the base, a tilting motor, a connecting shaft connected to the outer wall of one end of the output shaft of the tilting motor via a coupling, and a connecting plate fixed to the outer wall of one end of the connecting shaft. A drying mechanism is provided between the two side plates. The drying mechanism includes an installation cylinder with an air outlet on one side of its outer wall, a connecting block, several ceramic heating rods with both ends bolted to the inner wall of the installation cylinder, and a partition cylinder bolted to the inner wall of the installation cylinder. A screening assembly is provided inside the partition cylinder. The screening assembly includes a screening cylinder with several filter holes on its outer wall and several partitions fixed to the inner wall of the screening cylinder. A rotating assembly is provided on the outer wall of one end of the installation cylinder. The rotating assembly includes an installation plate and two rotating motors bolted to the outer wall of one side of the installation plate.

[0007] Preferably, a mounting bracket is fixed on one outer wall of the side plate, and the flipping motor is connected to the outer wall of the mounting bracket by bolts. One end of the connecting shaft passes through and is connected to the outer wall of the side plate by a bearing.

[0008] Preferably, the connecting block is fixed on one side of the outer wall of the two connecting plates, and the connecting block is connected to the outer wall of the mounting cylinder by bearings. A toothed ring is bolted to one side of the outer wall of the mounting cylinder.

[0009] The above scheme uses the rotation of the output shaft of the flip motor to drive the connecting shaft and the connecting plate to rotate, which in turn drives the connecting block and the mounting cylinder to rotate along the axis of the connecting shaft.

[0010] Preferably, the screening cylinder is bolted to the inner wall of one side of the mounting cylinder, and a baffle is bolted to the outer wall of one side of the screening cylinder. A first discharge port is opened on the inner wall of one side of the mounting cylinder between the partition cylinder and the screening cylinder, and a first sealing plug is inserted into the first discharge port. A plurality of second discharge ports are opened on the outer wall of one side of the mounting cylinder, and the plurality of second discharge ports are respectively located between a plurality of partitions, and a second sealing plug is inserted into each of the plurality of second discharge ports.

[0011] Preferably, a dustproof net is bolted to one side of the outer wall of the mounting cylinder, and the dustproof net is fitted onto the outer wall of the baffle.

[0012] Preferably, the mounting plate is fixed on one outer wall of one side of the two connecting plates, and the mounting plate is connected to the outer wall of one end of the mounting cylinder by bearings. Gears are fixed on the outer walls of one end of the output shafts of the two rotary motors, and the two gears mesh with the gear rings to form a transmission engagement.

[0013] The above method uses multiple sets of ceramic heating rods to generate heat, which then dries the tea leaves in the separating and sieving cylinders. The output shafts of two rotary motors rotate, driving gears to rotate. The gears then drive the gear ring and mounting cylinder to rotate, causing the sieving cylinder to sieve the tea leaves. The sieved tea leaves enter the space between the separating and sieving cylinders. The first sealing plug can then be removed to clean the sieved tea leaves. By removing several second sealing plugs in sequence, the tea leaves in the sieving cylinder can be cleaned.

[0014] The beneficial effects of this utility model are as follows:

[0015] Multiple sets of ceramic heating rods generate heat, which then dries the tea leaves in the separating and sieving cylinders. Two rotary motors rotate, driving gears to rotate. These gears, in turn, drive a gear ring and a mounting cylinder, causing the sieving cylinder to sieve the tea leaves. The sieved tea leaves then enter the space between the separating and sieving cylinders. The first sealing plug can then be removed to clean the sieved tea leaves. By removing several second sealing plugs in sequence, the tea leaves in the sieving cylinder can be cleaned. This system allows for sieving of the tea leaves during the drying process, avoiding breakage caused by sieving after drying and improving practicality. Attached Figure Description
