Description

Technical Field

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

[0002] Tea fermentation is a chemical reaction that mainly occurs after the oxidation of catechins to form colored substances such as theaflavins and thearubigins, changing the color, aroma and taste of tea. The higher the fermentation degree, the less theophylline content in the tea and the softer the taste.

[0003] During the production and fermentation process of tea, a fermentation box is used to control the fermentation temperature and humidity of tea. For example, a tea fermentation box disclosed in the utility model with the publication number CN217658022U includes a box body. A fermentation rack is slidably connected to the inner wall of the box body. A motor is installed on the outer wall of the bottom end of the fermentation rack. One end of the output shaft of the motor is connected to a rotating roller through a coupling. The outer wall of the rotating roller is connected with a placement tray by screws. In this utility model, the fermentation rack moves under the action of the second pulley, and the operation of entering and exiting the fermentation box is simple, and the fermentation is faster and more uniform. Moreover, during the fermentation process, it will be continuously and slowly turned over, and there is no need to regularly take it out and sort it many times, improving the use efficiency of the fermentation box.

[0004] However, after the tea in the above-mentioned fermentation box is fermented, the fermentation rack is taken out to remove the tea from the placement tray. During the process of removing the tea, the placement tray is fixedly connected to the rotating roller by screws, resulting in a more cumbersome process of removing the entire placement tray to pour out the tea, increasing the time required to remove the tea from the placement tray after fermentation is completed, thereby reducing the tea processing efficiency. Therefore, a tea fermentation box is proposed to solve the above problems. Content of the Utility Model

[0030] As Figures 1-5 shown, a tea fermentation box proposed by the present utility model includes a box body 1 and a box door 2 located on the box body 1. An air outlet 3 is provided at the upper end of the box body 1. A valve is fixedly installed outside the air outlet 3. The valve on the air outlet 3 is an electromagnetic valve, which is used to discharge the hot air and moisture in the box body 1. A driving member 4 is provided on the box body 1.

[0031] In the present utility model, the driving member 4 located inside the box body 1 can facilitate the operator to take and place the tea during fermentation, so as to improve the tea fermentation efficiency.

[0032] In an alternative embodiment, the driving member 4 includes a fixed driving motor 41 fixedly installed at the upper end of the box body 1. A connecting rod 42 is arranged inside the box body 1. A support rod 46 is fixedly connected to the outside of the connecting rod 42. A support semi-ring 43 is fixedly connected to the end of the support rod 46. A stopper 44 is hinged to the end of the support semi-ring 43. A tea tray 45 is placed inside the support semi-ring 43 and the stopper 44. Both the support semi-ring 43 and the stopper 44 are in a concave shape.

[0033] It should be noted that the number of connecting rods 42 and supporting semi-rings 43 is not less than one. The top connecting rod 42 is fixedly connected to the output shaft of the driving motor 41, and the bottom connecting rod 42 is rotatably connected to the inner bottom wall of the box body 1. The support rod 46 is L-shaped, and the number of support rods 46 is several. The several support rods 46 are symmetrically distributed on the upper and lower sides of the supporting semi-ring 43. After the supporting semi-ring 43 is supported and fixed by connecting the several connecting rods 42 and the support rods 46, while driving the supporting semi-ring 43 to rotate, it does not affect the taking and placing of the tea tray 45.

[0034] In this embodiment, through the stopper 44 on the supporting semi-ring 43, the tea tray 45 placed inside the supporting semi-ring 43 can be limited and fixed, so that the tea tray 45 can be placed on or removed from the supporting semi-ring 43 more conveniently, improving the convenience of tea taking and placing and providing the tea processing efficiency.

[0035] In an alternative embodiment, a limiting member 47 for limiting and fixing the stopper 44 is provided on the stopper 44 and the supporting semi-ring 43; the limiting member 47 includes a fixed cylinder 471 fixedly connected to the supporting semi-ring 43, the upper end of the stopper 44 is fixedly connected with a supporting cylinder 472, a pull rod 473 with one end extending to the inside of the fixed cylinder 471 is slidably connected to the inside of the supporting cylinder 472, a retaining ring 474 is fixedly connected to the outside of the pull rod 473, and a spring 475 is fixedly connected between the retaining ring 474 and the supporting cylinder 472.

[0036] It should be noted that the number of stoppers 44 is several, and the several stoppers 44 are symmetrically distributed in pairs at one end and the other end of the supporting semi-ring 43. The pull rod 473 is L-shaped, which is convenient for the operator to pull the L end of the pull rod 473 to drive the pull rod 473 to separate from the fixed cylinder 471.

[0037] In this embodiment, when the pull rod 473 is pulled to separate from the fixed cylinder 471, the stopper 44 is squeezed and rotated to separate from the tea tray 45, and the tea tray 45 is pulled out from the supporting semi-ring 43 to pour out the fermented tea. And after the stopper 44 is rotated to fit with the tea tray 45 placed inside the supporting semi-ring 43, the pull rod 473 can be pulled to extend into the fixed cylinder 471 to limit and fix the stopper 44 and the tea tray 45.

[0038] In an alternative embodiment, the fermentation member 5 includes a plurality of ventilation pipes 51 symmetrically and fixedly connected to the inner wall of the box body 1. The end of the left ventilation pipe 51 is communicated with a heating pipe 56, the heating pipe 56 is communicated with a humidifying pipe 57, a connecting pipe 53 is communicated between the left and right ventilation pipes 51, an air outlet pipe 58 is communicated with the outside of the ventilation pipe 51, and an air outlet 59 is opened on the outside of the air outlet pipe 58.

[0039] Among them, the connecting pipe 53 is semicircular and is distributed outside the connecting rod 42. While connecting the two ventilation pipes 51 through the connecting pipe 53 located outside the connecting rod 42, it does not affect the rotation of the connecting rod 42. The lower end of the air outlet pipe 58 is fixedly connected with a rubber rod 510, so that when the connecting rod 42 drives the support rod 46 and the support semi-ring 43 to rotate, it will not be blocked by the rubber rod 510. At the same time, the rubber rod 510 can also stir and flip the tea leaves on the tea tray 45.

[0040] In addition, the fermentation component 5 further includes a blower 55 fixedly installed at the lower end of the box body 1, a temperature sensor 52 fixedly installed on the inner top wall of the box body 1, and a humidity sensor 54 fixedly installed on the inner top wall of the box body 1.

[0041] It should be noted that the intake ends of the heating pipe 56 and the humidifying pipe 57 are respectively connected to the hot air and humid air delivery sources. A controller is provided on the box door 2 and is electrically connected to the temperature sensor 52 and the humidity sensor 54 respectively. The controller is used to set the temperature sensor 52 and the humidity sensor 54 to monitor the temperature and humidity values inside the box body 1. At the same time, the controller is also electrically connected to the blower 55, the solenoid valve, and the hot air and humid air delivery sources. That is, when the temperature sensor 52 and the humidity sensor 54 respectively monitor that the temperature and humidity inside the box body 1 are higher than the set values, the valve can be controlled to open and the blower 55 can be started to dissipate heat and dehumidify the inside of the box body 1. On the contrary, when the temperature and humidity values are lower than the set values, the hot air and humid air delivery sources are controlled to deliver hot air and humid air through the heating pipe 56 and the humidifying pipe 57 to ferment the tea leaves at a constant temperature and humidity.

[0042] The working principle of the above embodiment is as follows:

[0043] When the pulling rod 473 is separated from the fixed cylinder 471, the extrusion rotating block 44 is separated from the tea tray 45, and the tea tray 45 is pulled out from the supporting semi-ring 43 to pour out the fermented tea. After the rotating block 44 is fitted with the tea tray 45 placed in the supporting semi-ring 43, the pulling rod 473 can be extended into the fixed cylinder 471 to limit and fix the block 44 and the tea tray 45. After all the tea trays 45 containing the tea to be fermented are fixed, the driving motor 41 can be started to drive the tea tray 45 to rotate at a constant speed through the connecting rod 42, the support rod 46 and the supporting semi-ring 43. When the temperature sensor 52 and the humidity sensor 54 respectively monitor that the temperature and humidity in the box body 1 are higher than the set values, the valve can be controlled to open and the fan 55 can be started to dissipate heat and dehumidify the box body 1. On the contrary, when the temperature and humidity values are lower than the set values, the hot gas and moisture delivery source is controlled to deliver hot gas and moisture through the heating pipe 56 and the humidifying pipe 57 to ferment the tea at a constant temperature and humidity. At the same time, the rubber rod 510 below the air outlet pipe 58 can stir the tea, thereby improving the uniformity of heating and humidifying the tea by the heating pipe 56 and the humidifying pipe 57 during fermentation to provide the tea fermentation effect.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
