[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following preferred embodiments are given with reference to the accompanying drawings for further detailed description of the present invention. However, it should be noted that many details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the invention, and these aspects of the present invention can be realized even without these specific details.
[0017] Please refer to Figure 1-2 , the present invention provides a drying device and a drying method for quantitative tea leaves, and the technical solutions are as follows: A tea quantitative drying device includes an outer cylinder 1, a air supply component, a blowing component 12, an inner cylinder 2, a driving component and a controller. The outer cylinder 1, the air supply component, the blowing component 12, the inner cylinder 2, the driving component and the controller are all arranged in the device housing. The outer cylinder 1 is horizontally arranged in the device housing, and an air supply component is fixedly arranged on the outer cylinder 1. The air supply component includes an air supply housing 3, an air supply motor 4, an air supply fan blade 5 and a heating pipe 6. The air supply housing 3 is fixedly connected with the outer cylinder 1 and is communicated with the outer cylinder 1. The air supply motor 4 is fixedly arranged on the air supply housing 3, and the output end of the air supply motor 4 extends into the air supply housing 3 through the side wall of the air supply housing 3, and the output end of the air supply motor 4 is rotationally connected with the air supply housing 3. The air supply blade is arranged inside the air supply housing 3, and the air supply fan blade 5 is fixedly connected with the output end of the air supply motor 4. The heating pipe 6 is arranged in the air supply housing 3 and is located below the air supply fan blade 5. The air supply motor 4 drives the air supply fan blade 5 to rotate, and at the same time the heating pipe 6 heats the surrounding air, and the air supply fan blade 5 blows the hot air into the outer cylinder 1. The inner cylinder 2 is sleeved inside the outer cylinder 1, and a plurality of ventilation holes 7 communicating with the outer cylinder 1 are opened on the side wall of the inner cylinder 2, and the hot air enters the inner cylinder 2 through the ventilation holes 7 to dry the tea leaves in the inner cylinder 2.
[0018] An air blowing port is opened at one end of the outer cylinder 1, and one end of the inner cylinder 2 is rotationally connected with the air blowing port through a rotating bearing 8. The rotating bearing 8 is arranged inside the air blowing port, the outer side of the rotating bearing 8 is fixedly connected with the air blowing port, and the inner side of the rotating bearing 8 is fixedly connected with the inner cylinder 2. The other end of the inner cylinder 2 is fixedly connected with the driving component, and the driving component is rotationally connected with the outer cylinder 1. Specifically, the driving component includes a driving motor 9, an encoder 10 and a driving shaft 11. The driving motor 9 is fixedly arranged in the device housing. The encoder 10 is arranged on the driving motor 9 and is fixedly connected with the driving motor 9, and the output end of the encoder 10 is connected with the driving motor 9. The rotation angle of the driving motor 9 can be read by using the encoder 10. One end of the driving shaft 11 is fixedly connected with the output end of the driving motor 9, and the other end of the driving shaft 11 extends into the outer cylinder 1 through the outer cylinder 1 and is rotationally connected with the outer cylinder 1 through a driving shaft bearing. The outer side of the driving shaft bearing is fixedly connected with the outer cylinder 1, and the inner side of the driving shaft bearing is fixedly connected with the driving shaft 11. The end of the driving shaft 11 placed inside the outer cylinder 1 is fixedly connected with the inner cylinder 2. The driving motor 9 drives the driving shaft 11 to rotate, and the driving shaft 11 drives the inner cylinder 2 to rotate. Under the rotation of the inner cylinder 2, the tea leaves in the inner cylinder 2 follow the inner cylinder 2 to rotate. In order to make most of the tea leaves follow the inner cylinder 2 to rotate together, the rotation speed of the inner cylinder 2 is set within a certain rotation speed range. During the rotation process, the tea leaves do centrifugal motion, which can accelerate the drying effect of the tea leaves.
[0019] The air outlet serves as the feeding port for putting tea leaves into the inner cylinder 2. In order to close the air outlet while dispersing the tea leaves in the inner cylinder 2, in this embodiment, a blowing assembly 12 is hinged on the air outlet. The blowing assembly 12 includes a blowing housing 121, a blowing motor 122, a blowing impeller 123 and a heating wire 124. The blowing housing 121 is hinged to the outer side of the air outlet. The blowing housing 121 can be used to close the air outlet. When the tea leaves need to be put into the inner cylinder 2, the blowing housing 121 is opened, and the tea leaves can be put into the inner cylinder 2 through the air outlet. After the placement is completed, the blowing housing 121 is closed to prevent the tea leaves from flying out of the inner cylinder 2. The blowing motor 122 is fixedly arranged in the blowing housing 121. The blowing impeller 123 is arranged in the blowing housing 121, and the blowing impeller 123 is fixedly connected to the output end of the blowing motor 122. The heating wire 124 is fixedly arranged in the blowing housing 121, and the heating wire 124 is located in front of the blowing impeller 123. The blowing impeller 123 is arranged opposite to the air outlet. By controlling the operation of the blowing motor 122, the blowing motor 122 drives the blowing impeller 123 to rotate, and the blowing impeller 123 blows air into the inner cylinder 2 through the air outlet. When the driving motor 9 controls the rotation of the inner cylinder 2 to transport the tea leaves to a high place, the driving motor 9 can be stopped to make the inner cylinder 2 stop rotating. At this time, the tea leaves located at a high place fall naturally under the action of gravity. During the falling process, the tea leaves are dispersed by blowing, so that the tea leaves in the inner cylinder 2 are dried more evenly.
[0020] In order to better control the motors in each component and improve the drying efficiency, in this embodiment, the controller includes a control module, a data acquisition module and a timing module. The control module is electrically connected to the timing module and the data acquisition module respectively. The control module is used to send control instructions to control the motors in each component; the data acquisition module is used to collect the data of the encoder 10; the timing module is used to provide a timing function. The control module is electrically connected to the driving motor 9, the air supply motor 4, the heating tube 6, the blowing motor 122 and the heating wire 124 respectively, and the data acquisition module is electrically connected to the encoder 10. The control module controls the start and stop of the driving motor 9, so that the tea leaves can rotate with the inner cylinder 2 or when the inner cylinder 2 rotates a certain angle to transport the tea leaves to a high place, the tea leaves can fall freely under the action of gravity. The control module controls the start and stop and output power of the air supply motor 4 and the heating tube 6, and then controls the output of the air supply motor 4 and the heating tube 6, which can be adjusted according to the amount and drying degree of the tea leaves. The control module controls the start and stop and output power of the blowing motor 122 and the heating wire 124, and then ensures that when the tea leaves fall, the blowing is started to disperse the tea leaves. The data acquisition module collects the data information of the encoder 10, so as to obtain the rotation angle information of the driving motor 9, and then the driving motor 9 can be accurately controlled.
[0021] In order to obtain the environmental information of the inner cylinder 2 and further improve the drying efficiency, in this embodiment, a detection module is further included. The detection module includes a temperature sensor and a humidity sensor. The temperature sensor and the humidity sensor are electrically connected to the data acquisition module. The temperature sensor and the humidity sensor are arranged in the inner cylinder 2. The temperature sensor and the humidity sensor are used to detect the temperature and humidity in the inner cylinder 2. The data acquisition module analyzes the collected temperature data and humidity data, and the control module performs control output on each motor and the heating tube 6 according to the analysis result to achieve precise drying of the tea leaves.
[0022] The present application also discloses a drying method for a tea leaf quantitative drying device, and the method includes the following steps: S1. Put a certain amount of tea leaves into the inner cylinder 2, where the amount of the tea leaves accounts for 1 / 3 - 1 / 2 of the volume of the inner cylinder 2.
[0023] Specifically, rotate the blowing housing 121, open the blowing port, and place the tea leaves into the inner cylinder 2 through the blowing port. It is optimal that the amount of the tea leaves to be dried placed is 1 / 3 - 1 / 2 of the volume of the inner cylinder 2. After the tea leaves are placed, rotate the blowing housing 121 to close the blowing port.
[0024] S2. Send hot air into the inner cylinder 2, and at the same time, control the rotation of the inner cylinder 2.
[0025] Specifically, start the air supply motor 4, use the air supply motor 4 to drive the air supply fan blade 5 to rotate, synchronously start the heating tube 6. The air supply fan blade 5 blows the hot air to the outer cylinder 1, and then enters the inner cylinder 2 through the ventilation holes 7 on the inner cylinder 2 to dry the tea leaves in the inner cylinder 2. At the same time, start the driving motor 9, the driving motor 9 drives the driving shaft 11 to rotate, and the driving shaft 11 drives the inner cylinder 2 to rotate. Since the initial tea leaves have a large water content, by increasing the output power of the driving motor 9, the rotation speed of the inner cylinder 2 is increased, so that the tea leaves follow the rotation of the inner cylinder 2, and the tea leaves perform centrifugal motion to pre-dry the tea leaves.
[0026] S3. Collect the rotation angle of the inner cylinder 2. When the inner cylinder 2 rotates 180 - 190°, stop the rotation of the inner cylinder 2, and at the same time, blow air along the axial direction of the inner cylinder 2.
[0027] Specifically, after the pre-drying of the tea leaves is completed, the data acquisition module of the controller collects the data of the encoder 10. The encoder 10 detects the rotation angle of the output end of the drive motor 9. The control module controls the output of the drive motor 9 according to the rotation angle of the inner cylinder 2. When the inner cylinder 2 transports the tea leaves to a high place by rotation, for example, when it rotates 180 - 190°, the drive motor 9 is stopped, so that the tea leaves fall freely under gravity. During the falling process of the tea leaves, the blowing motor 122 is started. The blowing motor 122 drives the blowing impeller 123, and the blowing impeller 123 blows air to the inner cylinder 2. The tea leaves in the falling process are scattered by the horizontal and longitudinal blowing. The scattered tea leaves are more conducive to drying, improving the tea leaf drying efficiency.
[0028] S4. Repeat steps S2 - S3 until the tea leaves are completely dried.
[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
