Technical Field

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

[0002] Tea fermentation refers to the process of enzymatic oxidation of tea, forming dark substances such as theaflavins and thearubigins. Fermentation mostly occurs in a dedicated room where temperature and humidity can be controlled. There are many factors affecting fermentation, such as temperature, humidity, and the water content of tea leaves, etc.

[0003] However, the humidifier on the existing tea fermentation device lacks a structure for automatic water addition. When the water source in the humidifier is insufficient, it is often necessary for workers to manually add water to the humidifier, which is rather troublesome. If the workers forget to add water in time, it will also affect the fermentation quality of tea. For this reason, a fermentation device for tea production is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fermentation device for tea production to solve the problems raised in the above background art.

A water inlet pipe communicating with the water tank is fixedly connected to the outer wall of the humidifier. An electric valve is arranged on the water inlet pipe. An automatic opening and closing mechanism acting on the electric valve is arranged inside the water tank. The automatic opening and closing mechanism consists of a floating block, a slider, a column, a conductive block, electrode plates, and a signal transmitter.

[0006] As a further preference of this technical solution, the fermentation chamber and the installation groove are communicated through a ventilation gap.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a fermentation device for tea production includes a fermentation box 1, a fermentation chamber 15 is provided at the front end of the fermentation box 1, a movable door 2 is provided at the opening position of the fermentation chamber 15, a mounting groove 16 is provided on the side wall of the fermentation box 1, the fermentation chamber 15 and the mounting groove 16 are connected through a ventilation gap 17, a humidifier 4 is fixedly installed in the mounting groove 16, a water tank 7 is provided inside the humidifier 4, a water inlet pipe 5 connected to the water tank 7 is fixedly connected to the outer wall of the humidifier 4, an electric valve 6 is provided on the water inlet pipe 5, and an automatic opening and closing mechanism acting on the electric valve 6 is provided inside the water tank 7, and the automatic opening and closing mechanism is composed of a floating block 8, a slider 9, a column 11, a conductive block 12, an electrode sheet 14 and a signal transmitter 21.

[0021] Among them, the signal transmitter 21 is fixedly installed on the outer wall of the humidifier 4, and the signal transmitter 21 is connected to the built-in controller signal of the electric valve 6. The floating block 8 is suspended inside the water tank 7. The side wall of the floating block 8 is fixedly connected with a slider 9, and the slider 9 is slidably installed in the slide groove 10 opened on the inner wall of the water tank 7. The upper end of the floating block 8 is fixedly installed with a column 11, and the upper end of the column 11 is slidably inserted in the movable groove 13 opened on the top wall of the inner cavity of the water tank 7. The top of the column 11 is fixedly installed with a conductive block 12, and the two inner walls of the movable groove 13 are respectively fixedly installed with electrode sheets 14.

[0022] The gap between the two electrode sheets 14 is the disconnected part of the circuit between the signal transmitter 21 and the built-in power supply of the humidifier 4. When the water level in the water tank 7 drops to a certain level, the conductive block 12 on the column 11 will contact the two electrode sheets 14 on the inner wall of the movable groove 13, thereby connecting the circuit between the signal transmitter 21 and the built-in power supply of the humidifier 4. At this time, the signal transmitter 21 will send a signal to the built-in controller of the electric valve 6, and the built-in controller will control the electric valve 6 to open, thereby adding water to the inside of the water tank 7. As the water level rises, the floating block 8 will drive the conductive block 12 to move upward and separate from the electrode sheet 14, thereby turning off the signal transmitter 21. After losing the signal, the built-in controller of the electric valve 6 will control the electric valve 6 to close automatically, thereby automatically completing the water adding work inside the humidifier 4, avoiding the staff forgetting to add water in time, resulting in insufficient humidity in the fermentation box 1, and thus affecting the fermentation of tea.

[0023] A plurality of mounting racks 18 are fixedly mounted on two mutually symmetrical inner walls of the fermentation bin 15 , and a collection box 19 is provided on the mounting racks 18 .

[0024] When in use, tea leaves are placed in the collecting box 19 and the collecting box 19 is placed on the mounting frame 18, so that the tea leaves can be placed in layers, ensuring that the device can ferment more tea leaves in a limited space.

[0025] The bottom of the collecting box 19 is provided with a plurality of through holes 20 .

[0026] The through holes 20 can facilitate the circulation of moisture in the fermentation bin 15 .

[0027] Among them, a plurality of heating wires 22 are fixedly installed on the rear inner wall of the fermentation chamber 15.

[0028] The heating wire 22 can maintain a certain temperature in the fermentation chamber 15.

[0029] Among them, four universal wheels 3 are provided at the bottom of the fermentation box 1 , and the four universal wheels 3 are distributed at the four corners of the bottom of the fermentation box 1 .

[0030] The fermentation box 1 can be easily transported and moved by the provided universal wheels 3 .

[0031] The utility model provides a fermentation device for tea production, and the specific working principle is as follows:

[0032] In use, tea leaves are placed in multiple collection boxes 19, and multiple collection boxes 19 are placed on multiple mounting racks 18 respectively, so that tea leaves can be placed in layers, ensuring that the device can ferment more tea leaves in a limited space. The heating wire 22 can maintain a certain temperature in the fermentation bin 15, and the humidifier 4 can maintain a certain humidity in the fermentation bin 15. The automatic start-up and closing mechanism can control the opening and closing of the electric valve 6, thereby automatically completing the water addition work inside the humidifier 4, avoiding the staff forgetting to add water in time, resulting in insufficient humidity in the fermentation box 1, which in turn affects the fermentation of tea leaves.

[0033] The working principle of the automatic opening and closing mechanism is that the gap between the two electrode sheets 14 is the disconnecting part of the circuit between the signal transmitter 21 and the built-in power supply of the humidifier 4. When the water level in the water tank 7 drops to a certain level, the conductive block 12 on the column 11 will contact the two electrode sheets 14 on the inner wall of the movable groove 13, thereby connecting the circuit between the signal transmitter 21 and the built-in power supply of the humidifier 4. At this time, the signal transmitter 21 will send a signal to the built-in controller of the electric valve 6, and the built-in controller will control the electric valve 6 to open, thereby adding water to the inside of the water tank 7. As the water level rises, the floating block 8 will drive the conductive block 12 to move upward and disengage from the electrode sheet 14, thereby turning off the signal transmitter 21. After losing the signal, the built-in controller of the electric valve 6 will control the electric valve 6 to close automatically.

[0034] Although embodiments of the present utility model 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 utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
