DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a tea drying device for matcha production, including a fixed frame 1, a frame cover 6 is installed on the left side of the fixed frame 1, a processing cylinder 4 is movably installed in the inner cavity of the fixed frame 1, and an installation frame 2 is installed at the bottom right end of the fixed frame 1;

[0019] A transmission drying mechanism 3, the transmission drying mechanism 3 includes a transmission bevel gear 302 and a rotating rod 303, the rotating rod 303 is installed in the middle of the right side of the processing cylinder 4, the right end of the rotating rod 303 passes through the fixed frame 1 and extends to the upper end of the inner cavity of the installation frame 2, and a transmission bevel gear 302 is installed on the left side of the middle of the rotating rod 303.

[0020] The transmission drying mechanism 3 further includes a single-phase motor 301, a rotating bevel gear 304, a rotating rod 305, a vortex fan head 306, a conveying frame head 307 and a resistance heating plate 308. The conveying frame head 307 is installed at the bottom right end of the fixed frame 1, and the resistance heating plate 308 is installed at the bottom end of the inner cavity of the conveying frame head 307. A rotating rod 305 is installed at the middle and lower right side of the fixed frame 1 through a shaft bracket. A vortex fan head 306 is installed at the bottom end of the rotating rod 305, and a rotating bevel gear 304 is installed at the top end of the rotating rod 305. The rotating bevel gear 304 meshes with the transmission bevel gear 302. A single-phase motor 301 is installed at the upper right end of the inner cavity of the installation frame 2 through a mounting seat. The right end of the rotating rod 303 is connected to the output shaft of the single-phase motor 301. When drying matcha tea, place the tea into the processing cylinder 4, install the frame cover 6 on the left side of the fixed frame 1 to make the inside of the fixed frame 1 airtight, and then start the single-phase motor 301 and the resistance heating plate 308. When the single-phase motor 301 rotates, it drives the rotating rod 303 to rotate. When the rotating rod 303 rotates, it drives the transmission bevel gear 302 to rotate. Since the transmission bevel gear 302 and the rotating bevel gear 304 mesh with each other, it drives the rotating bevel gear 304 to rotate and drives the rotating rod 305 to rotate. The vortex fan head 306 is driven to rotate in the inner cavity of the conveying frame head 307 through the rotating rod 305. When the airflow generated by the rotation of the vortex fan head 306 contacts the resistance heating plate 308, the airflow becomes hot airflow and is transmitted to the inside of the fixed frame 1. During the drying operation, it can also drive the processing cylinder 4 to rotate. When the processing cylinder 4 rotates, the tea to be dried is tumbled, and the tumbling of the tea increases the drying efficiency, avoiding drying the tea by vibration during the drying operation and avoiding dead corners during drying, resulting in reduced drying efficiency and increased drying cost;

[0021] A conveying air hole is opened at the bottom right end of the fixed frame 1, the bottom end of the conveying frame head 307 has no shielding structure, and a control panel is installed outside the fixed frame 1. The single-phase motor 301 and the resistance heating plate 308 are electrically connected to the control panel, so that the airflow generated in the inner cavity of the conveying frame head 307 is conveyed to the inside of the fixed frame 1 through the conveying air hole;

[0022] The processing cylinder 4 has a circular structure. A number of round holes are provided around the outside of the processing cylinder 4. A rotating hole is provided in the middle of the right side of the fixed frame 1. In this way, the right end of the rotating rod 303 passes through the right end of the fixed frame 1 through the rotating hole;

[0023] The frame cover 6 has a circular structure. A movable frame plate 5 is installed in the middle of the right side of the frame cover 6. The movable frame plate 5 is located inside the processing cylinder 4. In this way, when the processing cylinder 4 rotates, it drives the tea leaves to roll, so that the tea leaves come into contact with and collide with the outside of the movable frame plate 5 to be scattered, increasing the efficiency during drying;

[0024] Circular slide rails 7 are installed around the right side of the frame cover 6 and around the right side of the inner cavity of the fixed frame 1. A circular slide bar 8 is slidably installed inside the circular slide rails 7. The right circular slide bar 8 is fixedly connected to the right side of the processing cylinder 4. The left side of the processing cylinder 4 contacts the outside of the left circular slide bar 8. In this way, when the processing cylinder 4 rotates, it drives the circular slide bar 8 to slide inside the circular slide rails 7. Through the cooperation of the circular slide bar 8 and the circular slide rails 7, the stability and flexibility of the processing cylinder 4 during rotation are increased.

[0025] Working principle: When the present utility model performs a drying operation on matcha tea leaves, the tea leaves are placed inside the processing cylinder 4, the frame cover 6 is installed on the left side of the fixed frame 1 to make the inside of the fixed frame 1 in a sealed state, and then the single-phase motor 301 and the resistance heating plate 308 are started. When the single-phase motor 301 rotates, it drives the rotating rod 303 to rotate. When the rotating rod 303 rotates, it drives the transmission bevel gear 302 to rotate. Since the transmission bevel gear 302 and the rotating bevel gear 304 are meshed with each other, it drives the rotating bevel gear 304 to rotate and drives the rotating rod 305 to rotate. The fan head 306 is driven by the rotating rod 305 to rotate inside the conveying frame head 307. When the air flow generated by the rotation of the fan head 306 contacts the resistance heating plate 308, the air flow becomes a hot air flow and is transmitted to the inside of the fixed frame 1. During the drying operation, it can also drive the processing cylinder 4 to rotate. When the processing cylinder 4 rotates, it tumbles the tea leaves to be dried. By tumbling the tea leaves, the drying efficiency is increased, avoiding drying the tea leaves by vibration during the drying operation, and avoiding dead corners during drying, resulting in a reduction in drying efficiency and an increase in drying cost.
