Description

Technical Field

[0001] This utility model relates to the field of tea fermentation technology, and in particular to a fermentation and drying room for golden flower fermented tea. Background Technology

[0002] Golden Flower Fermented Tea is a type of fermented tea with unique quality and health benefits. Its core characteristic lies in the "golden flowers" that grow on the tea leaves during fermentation. These "golden flowers" are actually *Eurotium cristatum*, a beneficial microorganism. Under specific temperature and humidity conditions, this microorganism grows and multiplies on the surface of the tea leaves. During fermentation, *Eurotium cristatum* secretes various enzymes that catalyze a series of complex biochemical reactions in the polyphenols, cellulose, proteins, and other components of the tea leaves, thus creating the unique flavor and quality of Golden Flower Fermented Tea. A Golden Flower Fermentation Chamber refers to a drying room used for the production of Fu brick tea for decades. It possesses a rich variety of beneficial microorganisms, which are highly conducive to the production of "golden flowers" (scientific name: *Eurotium cristatum*). The drying room contains abundant beneficial microorganisms that grow and multiply under specific temperature and humidity conditions, fermenting the tea leaves and causing the golden "golden flowers" to appear on their surface.

[0003] Modern fermentation rooms have incorporated technological improvements and innovations while retaining the advantages of traditional drying rooms. For example, they employ constant temperature and humidity systems to precisely control the temperature and humidity conditions within the fermentation room; they incorporate internal air circulation systems to ensure consistent temperature and humidity across all areas; and they utilize the condensate from air conditioning units for humidification, thus conserving water resources. These technological improvements have enhanced fermentation efficiency and tea quality. However, lighting conditions, especially natural light, significantly impact tea fermentation. Existing fermentation rooms are mostly opaque warehouses, relying on artificial lighting to control illumination, which not only requires substantial electricity but also fails to achieve ideal results.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-6As shown, this embodiment provides a fermentation and drying room for golden flower fermented tea, including a main steel frame 1, which provides the installation foundation for other components, ensuring the stability and firmness of the overall structure of the drying room, and ensuring that the fermentation and drying room can withstand various forces from the internal equipment, tea leaves, and the operation process. Transparent protective plates 2 are fixedly installed on the outer side of the main steel frame 1 to prevent external debris, dust, etc. from entering the drying room. Sealed operating doors 3 are hinged at both ends of the main steel frame 1 to facilitate the entry and exit of operators for tea loading and unloading, equipment maintenance, and other operations. The sealed operating doors 3 are designed with ventilation holes inside, and exhaust fans 4 are fixedly installed inside the ventilation holes. The function of the exhaust fans 4 is to promote the circulation and exchange of air in the drying room and remove the waste gas and moisture generated during the fermentation process. After exhausting from the drying chamber, fresh air is introduced to maintain a suitable fermentation environment and prevent the accumulation of waste gas and excessive humidity from affecting the quality of tea fermentation. The outside of the ventilation installation hole is designed with an airflow adjustment structure 5. The operator can adjust the airflow adjustment structure 5 to control the operation of the exhaust fan 4 according to the ventilation requirements at different stages of the fermentation process, so that the airflow environment in the drying chamber is more in line with the requirements of the fermentation process. The lower end of the main steel frame 1 is equipped with a heating drying pipe 6 to provide a heat source for the drying chamber. Positioning support holes 7 are opened on both sides of the main steel frame 1. The positioning support holes 7 are fitted with shading control components 8. The shading control components 8 can block some direct sunlight from entering the drying chamber, so as to prevent the temperature in the drying chamber from becoming too high due to direct sunlight, which would affect the stability of the fermentation environment.

[0023] The airflow regulating structure 5 includes an regulating slide 501, which is located on one side of the sealed operating door 3. Ventilation baffles 502 are slidably engaged at both ends of the regulating slide 501. The inner surface of the ventilation baffles 502 is in contact with the outer surface of the sealed operating door 3. A movable slider is designed on one side of the ventilation baffles 502, which is slidably engaged inside the regulating slide 501. A bidirectional screw 503 is rotatably engaged inside the regulating slide 501. Both ends of the bidirectional screw 503 are threadedly connected to the movable slider. A directional bevel gear 504 is fixedly installed at the center of the bidirectional screw 503, and a directional bevel gear 504 is rotatably engaged at the center of the regulating slide 501. 5. The adjusting bevel gear 505 and the directional bevel gear 504 mesh with each other. An adjusting knob 506 is fixedly welded to the outside of the adjusting bevel gear 505. During the fermentation process, the operator needs to closely observe the fermentation of the tea. If the humidity in the drying room is too high or the exhaust gas accumulates, and the ventilation volume needs to be increased, the adjusting knob 506 can be rotated clockwise or counterclockwise to make the bidirectional screw 503 drive the moving slider and the ventilation baffle 502 to further open the ventilation installation hole and increase the exhaust volume. Conversely, if the temperature of the fermentation environment drops too quickly or the external environmental factors cause the ventilation volume to be too large, the adjusting knob 506 can be rotated in the opposite direction to make the ventilation baffle 502 partially block the ventilation installation hole and reduce the exhaust volume.

[0024] The positioning support hole 7 includes a lower mounting hole 701 and an upper support hole 702. The lower mounting holes 701 are designed on both sides of the lower end of the main steel frame 1, providing a fixed point for the installation and positioning of the positioning mounting rod 801 in the shading control component 8. The upper support hole 702 is opened at the upper end of the lower mounting hole 701 and is used to install the support positioning rod 803. The support positioning rod 803 cooperates with the lower mounting hole 701 to jointly support and position the transparent shading cloth 802, ensuring that the transparent shading cloth 802 can maintain a flat and stable state on the drying room and effectively perform the shading function.

[0025] The shading control component 8 includes a positioning mounting rod 801, which is slidably engaged inside the lower mounting hole 701. A transparent light-blocking cloth 802 is fixedly installed between the positioning mounting rods 801. A support positioning rod 803 is slidably engaged inside the upper support hole 702. The outer surface of the support positioning rod 803 is in contact with the inner surface of the transparent light-blocking cloth 802. During periods of strong sunlight, the shading control component 8 is in the installed state, and the transparent light-blocking cloth 802 effectively blocks some direct sunlight from entering the drying room, maintaining a suitable temperature environment inside the drying room. Operators can observe the fermentation of tea leaves inside the drying room through the transparent light-blocking cloth 802. If it is a cloudy day or the sunlight is weak, shading is not required. Operators can pull out the support positioning rod 803 from the upper support hole 702 and then pull out the positioning mounting rod 801 from the lower mounting hole 701 to remove the shading control component 8, allowing the drying room to receive sufficient sunlight. Alternatively, the shading control component 8 can be left unused depending on the actual situation.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
