Description

Technical Field

[0001] This utility model relates to the field of tea production technology, and more specifically to a tea fermentation device for tea production. Background Technology

[0002] Tea fermentation is a crucial step in tea processing. Fermentation refers to the chemical reactions that occur in tea leaves under the influence of moisture and temperature, resulting in a series of product transformations and component changes. Through fermentation, the flavor, aroma, and color of tea leaves are significantly altered, thus creating different types of tea for drinking.

[0003] A search revealed an existing patent (publication number: CN209660338U) that discloses a tea fermentation device. During use, the tea leaves to be fermented are placed in a fermentation box to prevent dust from falling onto the fermenting tea leaves and making them unclean. The fermentation box is movably connected to a shelf on a storage rack, allowing the storage rack to fix the fermentation box within the fermentation chamber, further reducing dust in the fermentation area. An air pipe is installed inside the fermentation chamber to blow air out. The air outlet of the air pipe is connected to an air inlet pipe installed on the fermentation box, allowing air to be blown into the fermentation box to ensure normal fermentation. The gas inside the fermentation box flows out through the air outlet pipe, maintaining a balanced internal pressure. Similarly, the gas flowing into the fermentation chamber through the air outlet pipe is blown out through the air vent, maintaining a balanced internal pressure. However, in the process of realizing this utility model, the inventors discovered the following problems with the prior art: When fermenting tea, the tea leaves are piled up inside the fermentation box. As a result, the accumulation of the tea leaves causes a difference in the ventilation between the inside and outside of the tea leaves, which in turn leads to an uneven fermentation progress between the inside and outside of the tea leaves inside the same fermentation box, thus affecting the quality of the tea.

[0004] In view of this, this utility model proposes a tea fermentation device for tea production to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tea fermentation device for tea production, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a tea fermentation device for tea production, including a fermentation box, a door hinged to the front of the fermentation box, a fermentation tray for holding tea inside the fermentation box, dust filter ventilation nets embedded at the top and bottom of the fermentation tray, a ventilation component on the surface of the fermentation box, and a vibration component corresponding to the fermentation tray in the fermentation box.

[0007] The vibration assembly includes a lifting frame inserted into the top of the fermentation box, a platform fixedly installed on the inner wall of the lifting frame, a fermentation tray detachably installed on the surface of the platform, a geared motor fixedly installed on the top of the fermentation box, an eccentric shaft fixedly installed on the output shaft surface of the geared motor via a turntable, a swing seat slidably connected to the surface of the lifting frame, and the eccentric shaft passing through the surface of the swing seat and rotatably connected to the swing seat.

[0008] Furthermore, the surface of the cabinet door is provided with an observation window, a control panel, and a handle, and the control panel is electrically connected to an external power source via a wire.

[0009] As a further description of the above technical solution: the tea fermentation device for tea production has an observation window, which allows staff to easily observe the placement of the fermentation trays inside the fermentation box. The control panel allows staff to easily control the entire device, improving the ease of operation.

[0010] Furthermore, a limiting sleeve is fixedly installed on the inner bottom wall of the fermentation box, and the bottom end of the lifting frame is inserted into the limiting sleeve.

[0011] As a further description of the above technical solution: by setting a limit sleeve, the stability of the lifting frame during lifting and moving can be ensured.

[0012] Furthermore, the ventilation assembly includes an air pump fixedly installed on the upper left side of the fermentation chamber. An air duct is fixedly installed at the air pump's outlet end. An electric heating grid is installed on the inner wall of the air duct. The air outlet end of the air duct extends to the inner left side of the fermentation chamber and is fixedly installed with an air guide plate. An air outlet is opened on the surface of the air guide plate corresponding to the fermentation tray. A temperature and humidity sensor is fixedly installed on the inner right wall of the fermentation chamber. The electric heating grid is connected to the temperature and humidity sensor via a signal connection. A one-way exhaust valve is embedded in the lower right side of the fermentation chamber. An atomizing nozzle is embedded in the inner wall of the air duct. The input end of the atomizing nozzle is connected to an external pressurized distilled water tank via a pipe. A solenoid valve is installed on the surface of the atomizing nozzle and is connected to the temperature and humidity sensor via a signal connection.

[0013] As a further description of the above technical solution: by setting up a ventilation component, an air pump is used to pump outside air into the air duct, and the air guide plate guides the air evenly to the fermentation tray, ensuring that the tea leaves are evenly exposed to air. In addition, the temperature and humidity inside the fermentation box are monitored in real time by a temperature and humidity sensor. When heating is required, the electric heating network can be activated to heat the air. When humidification is required, the solenoid valve opens, and the distilled water in the pressurized distilled water tank can enter the atomizing nozzle through the pipe and be sprayed out through the atomizing nozzle to increase the humidity inside the fermentation box and ensure the temperature and humidity conditions required for tea fermentation.

[0014] Furthermore, the air pump has a desiccant box threadedly connected to its air inlet end.

[0015] As a further description of the above technical solution: by setting up a drying box, the desiccant in the drying box can be used to dry the incoming air, thus avoiding the impact of humid air on the quality of tea.

[0016] Furthermore, the fermentation tray includes a tray body and a tray cover. The tray cover is fastened to the surface of the tray body. Dust filter ventilation screens are respectively installed on the surfaces of the tray body and the tray cover. The surface of the tray is threaded with a threaded set screw. The surface of the tray body is provided with a positioning hole for the threaded end of the threaded set screw to be engaged.

[0017] As a further description of the above technical solution: when laying tea leaves, the lid of the tray can be opened, the tea leaves can be placed inside the tray, the lid can then be closed, and the fermentation tray can be placed on the platform surface. The fermentation tray can be positioned using threaded set screws to ensure that the tea leaves inside the fermentation tray can ferment stably.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Compared with existing technologies, this tea fermentation device for tea production lays the tea leaves flat inside a fermentation tray, which is then placed inside a fermentation box for fermentation. During fermentation, a dust filter and ventilation net ensures ventilation for the tea leaves and prevents dust from contacting them, thus ensuring tea quality. Furthermore, by incorporating a vibration component, a geared motor periodically drives the turntable and eccentric shaft to rotate, which in turn causes the swing seat to swing left and right on the surface of the lifting frame, simultaneously raising and lowering the lifting frame, which in turn causes the fermentation tray to vibrate. This promotes the movement of the tea leaves, ensuring the uniformity of the internal and external fermentation levels and guaranteeing the quality of the fermented tea.

[0020] 2. Compared with existing technologies, this tea fermentation device for tea production features an observation window for easy monitoring of the placement of fermentation trays inside the fermentation chamber, a control panel for convenient operation, and a limit sleeve to ensure stability during lifting and lowering. A ventilation system uses an air pump to draw outside air into the ductwork, and guides the air evenly to the fermentation trays, ensuring uniform airflow to the tea leaves. Temperature and humidity sensors monitor the internal temperature and humidity of the fermentation chamber in real time. When heating is needed, an electric heating grid is activated to heat the air; when humidification is required, a solenoid valve opens, allowing distilled water from a pressurized distillation tank to flow through pipes into atomizing nozzles, increasing humidity and maintaining the necessary temperature and humidity conditions for tea fermentation. A drying box with desiccant dries the incoming air, preventing moisture from negatively impacting tea quality. Attached Figure Description
