Description

Technical Field

[0001] This utility model relates to the field of black tea kneading technology, and in particular to a high-efficiency kneading device for black tea processing. Background Technology

[0002] Black tea, as one of the most widely consumed teas globally, is beloved by consumers for its unique color, aroma, and taste. In the processing of black tea, rolling is a crucial step. It not only affects the shape of the tea leaves, forming tightly rolled strips, but also plays a key role in the transformation of the tea's internal substances and the formation of its aroma.

[0003] Traditional black tea rolling methods rely primarily on manual labor. Workers use tools such as bamboo sieves and rolling machines to roll the tea leaves by hand or with simple mechanical power. However, this traditional method has many drawbacks. Manual rolling is inefficient, labor-intensive, and difficult to meet the needs of large-scale production. Furthermore, the rolling force, speed, and time are difficult to control precisely, resulting in inconsistent rolling effects and affecting the stability of black tea quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency kneading device for black tea processing. This device uses a first motor to drive a reciprocating screw, which in turn drives a translation plate and a kneading disc to move horizontally back and forth. Combined with the rotational kneading driven by a second motor, it forms a "rotation + translation" composite kneading mode, which significantly shortens the kneading time and optimizes the shape of the tea leaves.

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

[0006] A high-efficiency kneading device for black tea processing includes a housing, a plurality of support legs fixedly installed at the lower end of the housing, a protective shell provided inside the housing, a kneading disc rotatably connected inside the protective shell, and a second motor fixedly installed at the upper end of the protective shell, the output shaft of the second motor being coaxially fixed with the kneading disc.

[0007] Two fixing plates are fixedly installed on the upper end of the shell and are arranged symmetrically. A reciprocating mechanism for the reciprocating motion of the kneading disc is provided between the two fixing plates.

[0008] The lower end of the housing is provided with a discharge port, and the discharge port is provided with an opening and closing mechanism for the discharge port.

[0009] Preferably, the reciprocating mechanism includes a reciprocating screw rotatably connected between two fixed plates, a first motor is fixedly installed on the side wall of one of the fixed plates, the output shaft of the first motor is coaxially fixed with the reciprocating screw, a slide rod is fixedly installed between the two fixed plates, a translation plate is provided between the slide rod and the reciprocating screw, two electric push rods are fixedly installed on the upper end of the translation plate, and the telescopic ends of the two electric push rods are fixedly installed on the upper end of the protective shell.

[0010] Preferably, the translation plate is a right-angled U-shaped plate, and the vertical portions at both ends of the translation plate are respectively provided with threaded holes adapted to the reciprocating lead screw and sliding holes adapted to the slide rod.

[0011] Preferably, the opening and closing mechanism includes an opening on the side wall of the housing, and a closing plate is slidably connected inside the opening. The closing plate is elastically connected to the housing by two springs.

[0012] Preferably, both the closing plate and the fixing plate are L-shaped plates.

[0013] Preferably, the translation plate has a through hole for stopping the second motor.

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

[0015] The spiral pattern on the lower surface of the kneading disc enhances the curling force of the tea leaves, making the tea leaves more evenly stressed, increasing the yield of strips and the cell breakage rate, promoting the seepage of tea juice, and improving the fermentation effect of black tea.

[0016] The first motor drives the reciprocating screw, which drives the translation plate and kneading disc to move horizontally back and forth. Combined with the rotational kneading driven by the second motor, a "rotation + translation" compound kneading mode is formed, which significantly shortens the kneading time and optimizes the shape of the tea leaves.

[0017] The electric push rod allows for adjustment of the height of the protective shell and kneading disc inside the shell, which adapts to different tea types and kneading requirements, thus improving the versatility of the device.

[0018] The opening and closing mechanism makes it easier to open and close the discharge port. The discharge port can be opened by pulling the closing plate with the handle to overcome the spring force. The operation is simple and reliable. Attached Figure Description
