Description

Technical Field

[0001] This utility model relates to the field of tea preparation technology, specifically a dynamic tea roasting machine. Background Technology

[0002] Tea processing machinery refers to the mechanical equipment used to process tea. It includes tea picking machines, rolling machines, loosening machines, sieving machines, shaking machines, iron removal machines, vibrating sieves, stem picking machines, round sieves, rolling cutters, polishing machines, declumping machines, strip shaping machines, curling machines, grading machines, tea frying machines, baking machines, aroma enhancing machines, screening machines, fixing machines, hot air furnaces, drying machines, rolling machines, packaging machines, inner film machines, tea stem picking machines, and vacuum packaging machines.

[0003] Tea roasting machines are an essential piece of equipment in tea production. They are mainly used for drying and roasting tea. Their working principle is to use hot air to heat the tea leaves, causing them to lose a large amount of moisture and volatile components, thereby shrinking the tea leaves, forming aroma, and increasing the fragrance of the tea.

[0004] Tea roasting machines improve the uniformity of drying by using an internally rotating tea tray. However, because the tea leaves are relatively stacked in the tea tray, the airflow can only dry the surface of the tea leaves. The tea leaves at the bottom and middle are not fully and effectively in contact with the airflow during the drying process, resulting in long drying time and uneven drying. The best way to solve this problem is to turn the tea leaves over, but this requires manual stopping of the machine and removal of the tea tray. Therefore, a dynamic tea roasting machine that can automatically turn the tea leaves over is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic tea roasting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dynamic tea roasting machine includes a chassis, a door, a control panel, a heat exchanger, and a blower. The chassis is equipped with a door, a control panel, a heat exchanger, and a blower. The control panel controls the heat exchanger to send air to the blower. The chassis is equipped with a rotatable dynamic support, on which are mounted equally spaced trays. A material turning structure is mounted on the trays.

[0008] The material turning structure includes a rake frame, a connecting shaft, and material turning rake nails. A rotatable rake frame is mounted on the disc frame via the connecting shaft, and material turning rake nails are installed at equal intervals at the bottom of the rake frame.

[0009] Magnets are installed at both ends of the rake frame, and electromagnets are installed inside the machine housing. When the magnets are brought close to the electromagnets, they will be attracted.

[0010] As a further improvement of this utility model: the bottom of the dynamic support is provided with a turntable and a drive motor, and the drive motor drives the dynamic support to rotate by driving the turntable.

[0011] As a further embodiment of this utility model: the material turning structure also includes a crossbeam, which is installed on the inner side of the tray frame. The center point of the crossbeam is also the center point of the rotation of the dynamic support. The center point of the crossbeam is rotatably mounted to the connecting shaft through a bearing.

[0012] As a further improvement of this utility model: the rake frame is provided with a through hole, and the connecting shaft passes through the through hole and is slidably connected to the rake frame. The contact between the connecting shaft and the through hole can maintain the balance of the rake frame.

[0013] As a further embodiment of this utility model: the turning rake nails are arranged with the connecting shaft as the midpoint, and the turning rake nails on both sides of the connecting shaft are staggered. The gap between two adjacent turning rake nails corresponds to the arrangement position of the turning rake nails on the other side.

[0014] As a further improvement of this utility model, the control panel controls the energization of the electromagnet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This dynamic tea roasting machine uses a turning structure to turn the dynamically dried tea leaves, preventing the bottom or middle parts from not being able to effectively contact the airflow and dry. Therefore, by using a turning structure in conjunction with an electromagnet to turn the tea leaves, the bottom and middle parts of the tea leaves are turned up and come into contact with the airflow to dry, thus improving drying efficiency and uniformity.

[0021] Please see Figures 1-3In this embodiment of the utility model, a dynamic tea roasting machine includes a casing 1, a door 2, a control panel 3, a heat exchange heater 4, and a blower box 5. The casing 1 is equipped with the door 2, the control panel 3, the heat exchange heater 4, and the blower box 5. The control panel 3 controls the heat exchange heater 4 to send air to the blower box 5. A rotatable dynamic support 6 is provided inside the casing 1. The dynamic support 6 is equipped with equally spaced trays 11. A material turning structure 9 is installed on the trays 11.

[0022] The material turning structure 9 includes a rake frame 901, a connecting shaft 902, and material turning rake nails 904. A rotatable rake frame 901 is mounted on the disc frame 11 via the connecting shaft 902, and material turning rake nails 904 are installed at equal intervals at the bottom of the rake frame 901.

[0023] Magnets 10 are installed at both ends of the rake frame 901, and an electromagnet 12 is installed inside the machine housing 1. When the magnet 10 is close to the electromagnet 12, it will be attracted. The tea tray containing the tea leaves is placed into the tray frame 11, and the tray frame 11 will rotate together with the dynamic support 6. The turning structure 9 should rotate together with the dynamic support 6, but when it is close to the energized electromagnet 12, the electromagnet 12 generates a magnetic field and is attracted and stops rotating after the magnet 10 is close. This stirs and turns the tea leaves in the rotating tea tray, improving the uniformity of drying.

[0024] In a preferred embodiment, the bottom of the dynamic support 6 is provided with a turntable 7 and a drive motor 8. The drive motor 8 drives the dynamic support 6 to rotate by driving the turntable 7. The bellows 5 usually blows out from one side of the housing 1 and draws in from the other side to form a circulation. The circulation of airflow promotes the drying of tea leaves in the tea tray. However, since the airflow direction is fixed, the drying speed on both sides is inconsistent. Therefore, the dynamic support 6 is rotated by the drive motor 8 to achieve dynamic drying, which can effectively improve the drying uniformity.

[0025] In a preferred embodiment, the material-turning structure 9 further includes a crossbeam 905, which is installed on the inner side of the tray frame 11. The center point of the crossbeam 905 is also the center point of rotation of the dynamic support 6. The center point of the crossbeam 905 is rotatably mounted to the connecting shaft 902 via a bearing 903. In order to achieve uniform drying, the dynamic support 6 is driven to rotate by the drive motor 8. The material-turning structure 9 is installed on the dynamic support 6, but the material-turning structure 9 needs to rotate relatively stationary with the dynamic support 6 in order to achieve the material-turning effect. Therefore, the material-turning structure 9 and the dynamic support 6 are rotatably connected via a bearing 903 and a connecting shaft 902.

[0026] In a preferred embodiment, the rake frame 901 has a through hole, and the connecting shaft 902 passes through the through hole and is slidably connected to the rake frame 901. The contact between the connecting shaft 902 and the through hole can maintain the balance of the rake frame 901. The rake frame 901 is slidably mounted on the outside of the connecting shaft 902. During the process of placing the tea tray, the rake frame 901 needs to be raised to a certain distance to facilitate the placement of the tea tray. After being lowered, it naturally slides down to contact the tea leaves. The connection between the connecting shaft 902 and the rake frame 901 needs to maintain the balance of the rake frame 901.

[0027] In a preferred embodiment, the turning rake 904 is positioned with the connecting shaft 902 as the midpoint. The arrangement of the turning rake 904 on both sides of the connecting shaft 902 is staggered. The gap between two adjacent turning rakes 904 corresponds to the arrangement position of the turning rake 904 on the other side. When turning the tea leaves, the turning rake 904 will form rake grooves and tea piles on the tea leaves. When rotating to the other side of the turning rake 904, the contact point of the turning rake 904 is the tea pile, which fills the rake grooves on both sides and improves the uniformity of turning.

[0028] In a preferred embodiment, the control panel 3 controls the energization of the electromagnet 12. When the control panel 3 energizes the drive motor 8 to make the drive motor 8 work, the electromagnet 12 is also energized synchronously to generate a magnetic field. When the drive motor 8 is de-energized, the electromagnet 12 is also de-energized synchronously.

[0029] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0030] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
