Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tea kneading equipment, and in particular to an automatic kneading equipment for tea processing. Background Technology
[0002] Tea rolling involves using external force to break down cell structures, causing tea polyphenols, amino acids, and aromatic substances to seep out, providing a basis for fermentation or oxidation. At the same time, it shapes tea leaves into tight strips or granules to improve storage and transportation efficiency. With the development of technology, automatic tea rolling machines have gradually replaced manual tea rolling in order to increase tea processing output.
[0003] The tea rolling machine mainly consists of a frame, a rolling disc, a rolling cylinder, and a drive unit. When the rolling machine is working, the drive unit drives the rolling cylinder to work. The rolling cylinder, in conjunction with the rolling disc, repeatedly rolls the tea leaves. After the preset time is reached, the rolled tea leaves are fed into the machine.
[0004] Existing tea rolling machines have a problem with poor heat dissipation when rolling tender leaves. When the rolling drum works continuously to roll the leaves, the friction between the tea leaves and the rolling strips generates heat, which causes the temperature of the contact surface between the tea leaves and the rolling disc to rise. This leads to excessively high tea temperature, which causes non-tea polyphenol fermentation and produces a musty smell, thereby reducing the taste of the tea soup after subsequent brewing. Utility Model Content
[0005] The purpose of this invention is to solve the problem of poor heat dissipation in existing tea kneading machines, and to propose an automatic kneading device for tea processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic kneading device for tea processing includes a frame and a connecting rod assembly arranged equidistantly in a ring on the frame. An mounting ring is fixedly installed on the connecting rod assembly, and an adjusting component is provided on the mounting ring. A barrel lid is fixedly installed on the adjusting component. A kneading disc is fixedly installed on the frame, and a heat dissipation cylinder is fixedly installed on the mounting ring. A kneading cylinder is disposed inside the heat dissipation cylinder, and the circumference of the kneading cylinder is smaller than the circumference of the heat dissipation cylinder. A heat dissipation zone is formed between the kneading cylinder and the heat dissipation cylinder. A spiral air guide plate is provided within the heat dissipation zone, and a connecting hole is provided on the air guide plate. An annularly arranged air inlet hole is provided on the heat dissipation cylinder, and the air inlet hole communicates with the heat dissipation zone. When the heat dissipation cylinder moves, air enters the heat dissipation zone through the air inlet hole, and the air in the heat dissipation zone flows along the surface of the air guide plate.
[0008] To improve the heat dissipation effect of the kneading disc, preferably, a kneading strip is fixedly installed on the kneading disc, a fixing plate is fixedly installed on the kneading disc, and a vortex-shaped heat dissipation pipe is fixedly installed between the fixing plate and the kneading disc, with the end face of the heat dissipation pipe in contact with the kneading disc. When the heat dissipation pipe is filled with water, the heat dissipation pipe and the kneading disc undergo a heat exchange reaction, reducing the temperature of the heat dissipation disc.
[0009] To avoid rigid kneading of tea leaves, the kneading strips are further provided in at least 9 sets, with each set of 3 sets of kneading strips forming a kneading working area, and the hardness of the kneading strips in the kneading working area increasing sequentially in a clockwise direction.
[0010] To improve heat dissipation, preferably, multiple sets of air guide plates are provided, and the multiple sets of air guide plates are arranged in a ring at equal intervals between the heat dissipation cylinder and the kneading cylinder.
[0011] In order to drive the linkage assembly to work, preferably, the frame is mainly composed of three support legs, one of which is rotatably mounted with a pulley and fixedly mounted with a drive shaft, and the drive shaft is driven by one of the linkage assemblies.
[0012] To facilitate material feeding, preferably, a feeding through hole is provided in the middle of the kneading disc, and a feeding baffle is provided inside the feeding through hole.
[0013] Compared with the prior art, this utility model provides an automatic kneading device for tea processing, which has the following beneficial effects:
[0014] 1. This automatic tea processing kneading equipment uses air inlets in the heat dissipation cylinder in conjunction with air guide plates. When the connecting rod assembly works and drives the kneading cylinder and heat dissipation cylinder to move, the movement of the heat dissipation cylinder draws air from the outside through the air inlets into the heat dissipation area. The air is then guided by the air guide plates to flow to the bottom, allowing the airflow to directly blow on the tea leaves between the kneading disc and the kneading cylinder. This avoids the tea leaves from overheating and premature fermentation due to prolonged kneading, and also prevents the tea leaves from turning yellow due to increased temperature, thus improving the flavor of the tea when brewed.
[0015] 2. This automatic kneading equipment for tea processing introduces water into the heat dissipation pipes installed inside the kneading disc, causing a heat exchange reaction between the heat dissipation pipes and the surface of the kneading disc, thereby reducing the temperature of the kneading disc and further achieving a cooling effect.
[0016] 3. This automatic kneading equipment for tea processing uses kneading strips of soft, medium and hard materials in groups to mimic the pressure of manual kneading from light to heavy, thereby further improving the taste and mouthfeel of the tea soup after kneading.
[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model uses a heat dissipation cylinder and a wind guide plate to guide the air outside the equipment into the heat dissipation cylinder and blow the flowing air downwards onto the tea leaves, thereby reducing the temperature of the tea leaves and preventing the tea leaves from rising in temperature and undergoing a premature fermentation reaction.

[0025] Example:
[0026] Reference Figures 1-4An automatic kneading device for tea processing includes a frame 1 and connecting rod assemblies 3 arranged equidistantly in a ring on the frame 1. The frame 1 mainly consists of three support legs, one of which has a pulley rotatably mounted on it. The pulley is fixedly mounted to a drive shaft, which is fixedly mounted to one of the connecting rod assemblies 3. An mounting ring 4 is fixedly mounted on the connecting rod assembly 3. The connecting rod assembly 3 mainly consists of two connecting rods and a rotating shaft. One connecting rod is fixedly connected to the drive shaft, and the other connecting rod is fixedly mounted on the mounting ring 4. An adjusting component 10 is provided on the mounting ring 4. The adjusting component 10 includes a mounting bracket, which is fixedly mounted on the mounting ring. Mounted on mounting ring 4, guide rods are slidably mounted on the mounting frame. Two guide rods are symmetrically mounted on the mounting frame. A screw is threaded in the middle of the mounting frame. The bottom end of the screw is fixedly mounted to the motor via a coupling. The motor is fixedly mounted on the mounting plate. A bucket cover 11 is fixedly mounted on the lower surface of the mounting plate. This application is driven by an external motor. The motor is connected to the pulley via a belt to achieve the transmission effect. When the motor is working, the pulley rotates, causing the drive shaft to rotate, which in turn causes the connecting rod in the connecting rod assembly 3 to rotate and work. Furthermore, the connecting rod drives the mounting ring 4 to move, thereby ensuring the normal operation of the equipment.
[0027] A kneading disc 2 is fixedly mounted on the frame 1, and a heat dissipation cylinder 5 is fixedly mounted on the mounting ring 4. A kneading cylinder 8 is disposed inside the heat dissipation cylinder 5, forming a heat dissipation zone between the kneading cylinder 8 and the heat dissipation cylinder 5. A spiral air guide plate 6 is disposed within the heat dissipation zone. Multiple sets of air guide plates 6 are arranged in a ring at equal intervals between the heat dissipation cylinder 5 and the kneading cylinder 8. In this application, the preferred number of air guide plates 6 is 10 sets. The heat dissipation zone is divided into multiple zones by the 10 sets of air guide plates 6, and the multiple heat dissipation zones are connected by connecting holes 7 to maintain a relatively stable air pressure between the heat dissipation zones and prevent heat loss. When the cylinder 5 moves, air usually enters from the front, resulting in less air in the heat dissipation area on the back side of the cylinder 5 and poor air flow. The air guide plate 6 is provided with a connecting hole 7, and the heat dissipation cylinder 5 is provided with annularly arranged air inlets 9. The air inlets 9 are connected to the heat dissipation area. When the heat dissipation cylinder 5 moves, air enters the heat dissipation area through the air inlets 9. The air in the heat dissipation area flows along the surface of the air guide plate 6 and is guided downward by the air guide plate 6 so that the air blows directly onto the tea leaves above the kneading disc 2, thus preventing the tea leaves from undergoing premature fermentation due to the increased temperature after kneading and friction.
[0028] Specifically, the air inlet 9 of the heat sink 5 is used in conjunction with the air guide plate 6. When the connecting rod assembly 3 works and drives the kneading cylinder 8 and the heat sink 5 to move, the movement of the heat sink 5 causes the outside air to flow into the heat dissipation area through the air inlet 9. The air is further guided by the air guide plate 6 to flow to the bottom, so that the air flows directly to the tea leaves between the kneading disc 2 and the kneading cylinder 8. This avoids the tea leaves from overheating due to prolonged kneading and premature fermentation, and also avoids the problem of the tea leaves turning yellow after the temperature rises, thus improving the taste of the tea when brewed.
[0029] A kneading strip 21 is fixedly installed on the kneading disc 2. A fixing disc 22 is also fixedly installed on the kneading disc 2. A vortex-shaped heat dissipation pipe 23 is fixedly installed between the fixing disc 22 and the kneading disc 2. Both ends of the heat dissipation pipe 23 extend to the bottom of the kneading disc 2 and are provided with connecting pipes. The two connecting pipes are a water inlet pipe and a water outlet pipe, respectively. The end face of the heat dissipation pipe 23 is in contact with the kneading disc 2. When the heat dissipation pipe 23 is filled with water, a heat exchange reaction occurs between the heat dissipation pipe 23 and the kneading disc 2, reducing the temperature of the heat dissipation disc. The kneading strip 21 is provided with at least 9 The kneading strips 21 are arranged in groups of three, forming a kneading working area. The hardness of the kneading strips 21 in the kneading working area increases sequentially in a clockwise direction. The preferred number of kneading strips 21 in this application is 12 groups, which are arranged in a ring at equal intervals above the kneading disc 2. The three kneading strips 21 in the kneading working area are made of silicone, spring steel and stainless steel, respectively, and are installed in a clockwise direction. This allows for pressure from light to heavy when kneading the tea leaves, avoiding damage to the tea leaves caused by rigid kneading.
[0030] Specifically, water is introduced into the heat dissipation pipe 23 installed in the kneading disc 2, causing a heat exchange reaction between the heat dissipation pipe 23 and the surface of the kneading disc 2, thereby reducing the temperature of the kneading disc 2 and further achieving a cooling effect. The kneading strips 21 used in groups are made of soft, medium and hard materials respectively, thereby mimicking the pressure of manual kneading from light to heavy, further improving the taste and mouthfeel of the tea soup brewed after kneading.
[0031] A feeding through hole is provided in the middle of the kneading disc 2. A feeding baffle 12 is installed inside the feeding through hole with an interference fit. The diameter of the feeding baffle 12 is the same as the diameter of the feeding through hole. When the equipment is working, the feeding baffle 12 is installed inside the feeding through hole, which effectively prevents the tea leaves from falling off during the kneading process.
[0032] In this invention, tea leaves are first poured into the kneading cylinder 8. The adjustment component 10 drives the cylinder cover 11 to move down, and then the kneading cylinder 8 is closed. The external motor drives the pulley to rotate via a belt, which in turn drives the connecting rod assembly 3 to work. The connecting rod assembly 3 drives the heat dissipation cylinder 5 to move. During the movement, the air outside the heat dissipation cylinder 5 flows into the heat dissipation area through the connecting hole 7. The air is guided to the bottom of the heat dissipation cylinder 5 by the air guide plate 6 and blows directly onto the tea leaves to prevent the tea leaves from getting too hot due to friction.
[0033] While the connecting component is working, the heat dissipation pipe 23 is filled with water through the water inlet and the external water inlet pipe. The water in the heat dissipation pipe 23 flows and the heat dissipation pipe 23 comes into contact with the kneading disc 2, thereby causing heat exchange and reducing the temperature of the kneading disc 2. This further reduces the temperature generated by the friction between the tea leaves and the kneading strip 21. After the tea leaves are kneaded, the feeding baffle 12 is removed, and the tea leaves can be taken off the kneading disc 2.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
