Description

Technical Field

[0001] The utility model relates to the technical field of tea preparation, in particular to a tea fermentation device. Background Art

[0002] The production of tea mainly requires the processes of picking, withering, killing green leaves, rolling, fermentation, and drying; and the fermentation process is the key step in producing the aroma and unique flavor of tea. However, since the tea leaves have been withered before fermentation, the leaves have become softer and the volume has been greatly reduced. In addition, the killing green leaves and rolling processes are also carried out before fermentation. The purpose is to break the cells of the tea leaves, and the tea juice overflows and adheres to the surface of the tea leaves, which is conducive to the contact between polyphenol oxidase and polyphenols to promote the fermentation of the tea leaves. Both processes will cause the volume of the tea leaves to become further smaller, and under the adsorption of the tea juice, the tea leaves will adhere to each other, which is not conducive to the progress of the chemical reaction. Therefore, the tea leaves must be turned over during the fermentation process. In the prior art, the tea leaves are usually taken out of the fermentation box and then turned over manually. However, the temperature and humidity need to be controlled during the fermentation of the tea leaves. Taking the tea leaves out of the fermentation box will affect the normal fermentation process of the tea leaves, thereby affecting the product quality. Alternatively, a drum-type fermentation device is used to ferment the tea leaves. However, the amount of tea leaves fermented at a single time is small, which is not conducive to rapid production. When a load-bearing fermentation device is used to ferment the tea leaves, it is difficult to turn the tea leaves over completely. Although the amount of tea leaves fermented each time is larger, the tea leaves cannot be fully fermented, which affects the product quality. Utility Model Content

[0003] In view of the deficiencies of the above-mentioned related prior arts, the present application provides a tea fermentation device, which can shake and turn the tea during the fermentation process, thereby preventing the tea from clumping and ensuring the fermentation effect, and has strong practicality.

[0007] Furthermore, a gear ring is provided on the outer side of the support plate, the gear ring is meshed with the gear, the gear is sleeved on the transmission shaft, the transmission shaft is rotatably installed on the fermentation box, and is connected to the output end of the power equipment.

[0008] Furthermore, a plurality of positioning rods are provided along the circumferential direction on the bottom surface of the bearing frame. The positioning rods are passed through the support plate. A retaining ring is provided at the lower end of the positioning rod. A first spring is sleeved on the positioning rod. Both ends of the first spring abut against the retaining ring and the support plate respectively and are always in a compressed state.

[0009] Furthermore, a plurality of through holes are provided on the bottom and side walls of the carrying frame.

[0010] Furthermore, the center of the horizontal plate is sleeved on the support rod, and the two ends are sleeved on the vertical rod. The upper end of the vertical rod is installed on the connecting plate, and the connecting plate is installed on the support rod. A second spring is sleeved on the vertical rod.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] like Figure 1-Figure 4 As shown, this example provides a tea fermentation device, including: a fermentation box 100, a supporting mechanism 200, and a turning mechanism 300.

[0021] A plurality of atomizing nozzles and electric heating tubes are provided inside the fermentation box 100 to control the humidity and temperature in the fermentation box 100; the supporting mechanism 200 includes a supporting rod 201 vertically installed in the fermentation box 100, and a plurality of supporting plates 202 are arranged at intervals in the vertical direction and rotate around their axes on the supporting rod 201, and a supporting frame 203 that rotates synchronously and moves in the vertical direction is provided on the supporting plate 202 for carrying tea leaves; the turning mechanism 300 includes a plurality of horizontal plates 301 respectively arranged above the supporting frames 203 and moving in the vertical direction, and a plurality of turning rods 302 are provided on the bottom surface of the horizontal plate 301 along its length direction for turning the tea leaves.

[0022] Specifically, a gear ring 204 is provided on the outer side of the support plate 202, and the gear ring 204 is meshed with a gear 205. The gear 205 is sleeved on a transmission shaft 206. The transmission shaft 206 is rotatably installed on the fermentation box 100 and connected to the output end of the power equipment. When the fermentation operation is carried out, the transmission shaft 206 is driven to rotate by the power equipment, and the gear 205 will drive the gear ring 204 to rotate, and the support plate 202 starts to rotate, and drives the supporting frame 203 to start rotating. At this time, relative movement occurs between the flipping rod 302 and the supporting frame 203, thereby flipping the tea leaves.

[0023] Specifically, a plurality of through holes 210 are provided on the bottom and side walls of the carrying frame 203 , so that the liquid sprayed by the atomizing nozzle can adhere to the surface of the tea leaves more smoothly, so as to keep the tea leaves in various places of the carrying frame 203 at a constant temperature and humidity.

[0024] Specifically, in order to ensure that the supporting frame 203 can smoothly rotate synchronously with the support plate 202, a plurality of positioning rods 207 are provided on the bottom surface of the supporting frame 203 along the circumferential direction. The positioning rods 207 are inserted into the support plate 202. A retaining ring 208 is provided at the lower end of the positioning rod 207, and a first spring 209 is sleeved on the positioning rod 207. The two ends of the first spring 209 respectively abut against the retaining ring 208 and the support plate 202, and are always in a compressed state. When the supporting frame 203 moves upward under the action of external force, the first spring 209 is further compressed. When the external force on the supporting frame 203 is cancelled, the supporting frame 203 will move downward rapidly under the elastic force of the first spring 209 until it abuts against the support plate 202. At this time, the tea leaves in the supporting frame 203 will shake, thereby shaking out the clumped tea leaves.

[0025] Specifically, in order to ensure the flipping effect of the flipping rod 302 on the tea leaves, the flipping rod 302 should be able to move up and down synchronously with the supporting frame 203. The center of the horizontal plate 301 is sleeved on the supporting rod 201, and the two ends are sleeved on the vertical rod 303. The upper end of the vertical rod 303 is installed on the connecting plate 304, and the connecting plate 304 is installed on the supporting rod 201. A second spring 305 is sleeved on the vertical rod 303, and the two ends of the second spring 305 are respectively abutted against the horizontal plate 301 and the connecting plate 304, and are always in a compressed state. When the supporting frame 203 moves upward, it will drive the horizontal plate 301 to move upward together, and the second spring 305 is further compressed, and when the supporting frame 203 moves downward, the horizontal plate 301 can move downward under the action of the second spring 305.

[0026] Specifically, a third spring 306 is provided between the transverse plate 301 and the connecting plate 304. The third spring 306 is sleeved on the support rod 201, and both ends of the third spring 306 are respectively abutted against the transverse plate 301 and the connecting plate 304, and is always in a compressed state. The third spring 306 and the second spring 305 jointly apply a downward force to the transverse plate 301 to ensure that the transverse plate 301 can move synchronously with the supporting frame 203.

[0027] Specifically, in order to make the supporting frame 203 continuously reciprocate in the vertical direction during the rotation process, the lower end of the vertical rod 303 is installed on the top ring 307, and the outer wall of the supporting frame 203 is provided with two support rods 211, and the support rod 211 is mounted on the top ring 307. The top ring 307 includes two first horizontal sections arranged symmetrically with the center, one end of the first horizontal section is connected with an inclined section, the upper end of the inclined section is connected to the second horizontal section, and the second horizontal section is higher than the first horizontal section, and the second horizontal section is connected to the other end of the other first horizontal section through the vertical section. When the support rod 211 is located on the first horizontal section, the supporting frame 203 is located at the lowest point, and when the support rod 211 moves from the first horizontal section to the second horizontal section, the supporting frame 203 gradually moves upward, and the first spring 209 is further compressed, and when the support rod 211 moves from the second horizontal section to the first horizontal section, the support rod 211 will instantly fall on the first horizontal section, thereby giving the tea leaves a shaking force, thereby shaking the tea leaves apart.

[0028] More specifically, the support rod 201 can be connected to the movable end of a horizontal linear mechanism, and the support rod 201 can be moved out of the fermentation box 100 when taking out the tea leaves.

[0029] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
