Description

Technical Field

[0001] The utility model relates to the field of tea processing equipment, in particular to a tea rehumidification machine. Background Art

[0002] Moisture regain is an important process that affects the quality of tea. During the withering process, the tea leaves lose a lot of moisture. The subsequent rolling process requires the tea leaves to have a certain moisture content to be completed. Therefore, moisture regain is needed to increase the moisture content of the tea leaves to meet the needs of the rolling process.

[0003] The existing rehumidification machine is usually controlled by a humidifier and a humidity sensor inside the device. Although the generated water mist can achieve the rehumidification of tea leaves, the water mist particles are easy to settle and form droplets, resulting in excessive humidity of the local tea leaves, resulting in uneven rehumidification effect of the tea leaves. The purpose of the utility model is to propose a new tea rehumidification machine structure to solve the above technical problems. Utility Model Content

[0004] The utility model aims to provide a tea rehumidification machine to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: it includes a base, a cylinder, a conveyor belt, a water mist nozzle, an input fan and an output fan. The cylinder is installed on the base and can rotate to form a rotating pair with the base. The cylinder is inclined. The conveyor belt is located below the left end of the cylinder for conveying tea leaves. The water mist nozzle is located on the left side of the cylinder. The water mist nozzle is connected to an external atomizing device. The input fan and the output fan are respectively located on the left side and the right side of the cylinder. The input fan and the output fan are respectively used to input water vapor into the cylinder and output water vapor.

[0006] In order to optimize the above technical solution, further measures are taken as follows: a motor is installed on the base, and belts are sleeved on the side of the cylinder and the motor shaft to realize the transmission connection between the cylinder and the motor to form a rotating pair, and the transmission power output is stabilized by the belt.

[0007] As a further improvement of the above technical solution: it also includes an infrared lamp tube, which is connected to the side of the output fan. The inner surface of the cylinder is mirror-like and the light generated by the infrared lamp tube is directed to the inner surface of the cylinder. The infrared light generated by the infrared lamp tube is reflected in the cylinder to heat the water mist, which can inhibit the water mist from combining to form large particle droplets, which helps to reduce the large particle droplets falling on the tea leaves and causing the tea leaves to be too moist.

[0008] As a further improvement of the technical solution: an annular groove is formed on the inner side of the cylinder, and the radius of the annular groove gradually decreases from the left end to the right end of the cylinder along the axis of the cylinder. The stepped annular groove can cause the tea leaves to turn over during the movement inside the cylinder, thereby causing the tea leaves to regain moisture evenly. In addition, the travel of the tea leaves inside the cylinder can be extended, which is helpful for the tea leaves to combine with the water mist.

[0009] As an improvement to the aforementioned technical solution: the axes of the input fan and the output fan coincide with the axis of the cylinder, ensuring that the input fan and the output fan can function stably and directionally migrate the water mist, thereby achieving the purpose of rehumidification while preventing a large amount of water mist from settling in the cylinder and causing excessive humidity in the tea leaves.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a tea rehumidification machine, which can realize the rehumidification of the transported tea leaves by cooperating with an input fan and an output fan to move water mist in a direction, and can also prevent a large amount of water mist from settling at the bottom of the cylinder to cause excessive humidity of the tea leaves, thereby helping to improve the rehumidification quality of the tea leaves.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-2The utility model provides a tea rehumidification machine, including a base 1, a cylinder 2, a conveyor belt 3, a water mist nozzle 4, an input fan 5, an output fan 6 and an infrared lamp 7. The cylinder 2 is installed on the base 1 and can rotate to form a rotating pair with the base 1. A motor 101 is installed on the base 1. Belts are sleeved on the side of the cylinder 2 and the rotating shaft of the motor 101 to realize the transmission connection between the cylinder 2 and the motor 101 to form a rotating pair. An annular groove 201 is formed on the inner side of the cylinder 2. Along the axial direction of the cylinder 2 from the left end of the cylinder 2 to the right end of the cylinder 2, the radius of the annular groove 201 gradually decreases, and the cylinder 2 is tilted on the base 1 through a bearing seat.

[0019] The conveyor belt 3 is located below the left end of the cylinder 2 and is used to convey tea leaves. The conveyor belt 3 is provided to receive the tea leaves falling from the left end of the cylinder 2 and convey them outward.

[0020] The water mist nozzle 4 is located on the left side of the cylinder 2 . The water mist nozzle 4 is connected to an external atomizing device. The water mist generated by the atomizing device is sprayed into the inner side of the cylinder 2 through the atomizing nozzle 4 .

[0021] The input fan 5 and the output fan 6 are located on the left side and the right side of the cylinder 2 respectively. The input fan 5 and the output fan 6 are used to input water vapor into the cylinder 2 and output water vapor respectively. The axes of the input fan 5 and the output fan 6 coincide with the axis of the cylinder 2.

[0022] The infrared lamp tube 7 is connected to the side of the output fan 6 , the inner surface of the cylinder 2 is mirror-like and the light generated by the infrared lamp tube 7 is directed toward the inner surface of the cylinder 2 .

[0023] Working principle: tea leaves are placed inside the cylinder 2 from the right end. During the process, since the cylinder 2 is tilted and the cylinder 2 is driven by the motor 101 through the belt, the tea leaves can slide along the inside of the cylinder 2 to the left end of the cylinder 2 and finally fall on the conveyor belt 3 to be transported to the middle section. Since there is a continuous annular groove 201 with a regularly changing radius inside the cylinder 2, the tea leaves will be partially turned over when passing through the annular groove 201, which helps the tea leaves to be evenly contacted with the water mist sprayed from the water mist nozzle 4, thereby further improving the moisture regain effect.

[0024] The water mist sprayed from the water mist nozzle 4 is brought into the interior of the cylinder 2 by the input fan 5 and comes into contact with the tea leaves to achieve rehumidification. Subsequently, the water mist leaves the cylinder 2 driven by the output fan 6. This is intended to prevent the water mist from settling in large quantities under the action of gravity, resulting in excessive moisture in the tea leaves, and to control the rehumidification quality. In addition, the infrared light generated by the infrared light in the process can act on the water mist after being reflected from the inner side of the cylinder 2, thereby suppressing the water mist and preventing the water mist droplets from combining to form large particle droplets.
