[0001] This utility model relates to the field of yellow tea processing, and in particular to a yellow tea fermentation room. Background Technology

[0002] Yellowing is a unique process in the production of yellow tea. It refers to the process of piling up the tea leaves in a humid and hot environment after the tea has been withered, rolled, or initially dried, causing the tea leaves to turn yellow. Yellowing is usually carried out in a yellowing room, where hot and humid air is introduced to trigger reactions such as the oxidation of tea polyphenols and the hydrolysis of polysaccharides.

[0003] In existing technology, hot and humid air is usually introduced from the top of the yellowing room, and the yellow tea is yellowed by the downward flow of the hot and humid air. However, when using this method, there will be a large difference in temperature and humidity inside the yellowing room, which will result in poor yellowing effect of the yellow tea.

Detailed Implementation

[0021] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-2As shown, this embodiment discloses a yellow tea fermentation room. Both ends of the top inner side of the fermentation room body 1 are fixed with air supply channels 2. Multiple air outlets 201 are provided on the side of the two air supply channels 2 that are close to each other, and the ends of the air supply channels 2 are connected to the external air supply device. A baffle plate 3 is provided below the two air supply channels 2. The upper and lower sides of the baffle plate 3 are fixedly connected to the corresponding air supply channels 2 and the fermentation room body 1, respectively. A guide cavity 4 is formed between the baffle plate 3 and the side wall of the fermentation room body 1 on the same side, and multiple guide holes 301 are evenly arranged on the baffle plate 3.

[0023] In this embodiment, the guide hole 301 is long and narrow, and its length direction is set horizontally. The air supply device is used to send the hot and humid air into the air supply channel 2. After flowing in the air supply channel 2, it quickly enters the top of the inner side of the humidification room body 1 through the air outlet 201. The hot and humid air flows downward rapidly and can enter the guide cavity 4 through the guide hole 301 at the bottom of the baffle plate 3. After flowing in the guide cavity 4, it can enter the area between the two baffle plates 3 through the upper guide hole 301. This makes the temperature and humidity inside the humidification room body 1 more uniform.

[0024] By adopting this scheme and setting up the above structure, the uniformity of temperature and humidity inside the yellowing chamber 1 is improved, thereby enhancing the yellowing effect on yellow tea.

[0025] Further optimize the plan, such as Figure 3 As shown, the main body 1 of the sumptuous room includes a box 11. A pair of anti-collision doors 12 are provided on the front side of the box 11. The sides of the anti-collision doors 12 that are far apart from each other are respectively hinged to the box 11.

[0026] Specifically, the crash barrier 12 includes a door body 121 hinged to the housing 11, and a crash barrier 122 is provided at the bottom front side of the door body 121. The crash barrier 122 is a curved panel, with both ends of the curved panel fixedly connected to the door body 121, and the protrusions of the two curved panels are positioned forward and close to each other. The crash barrier 122 can protect the door body 121 and also facilitate the entry of the transfer vehicle into the housing 11.

[0027] Further optimize the plan, such as Figure 2 As shown, a sliding door 13 is provided on the rear side of the box 11. The sliding door 13 allows the trolley to be pushed out from the rear side of the box 11 after the yellow tea has finished fermenting.

[0028] Further optimize the plan, such as Figure 3 As shown, it also includes a control device 5, which can automatically control the temperature, humidity and fermentation time inside the fermentation chamber 1.

[0029] Specifically, the control device 5 includes a PLC controller, a temperature sensor, and a humidity sensor. The temperature sensor, humidity sensor, and air supply device are electrically connected to the PLC controller. The temperature sensor and humidity sensor are installed at multiple points inside the housing 11 to detect the temperature and humidity inside the housing 11 and feed the detection results back to the PLC controller in the form of signals. After receiving the temperature and humidity signals, the PLC controller controls the start and stop of the air supply device and the air supply volume.

[0030] In a further optimized design, structural plates 6 are fixedly connected to the bottom of the two wind deflectors 3 on the side away from each other. The ends of the two structural plates 6 extend in opposite directions and form a slit 7 between them and the corresponding side wall of the main body 1 of the sump. A fan 8 is fixedly installed on the top of the flow channel 4 on the side close to the wind deflector 3.

[0031] In this embodiment, the fan 8 is electrically connected to the PLC controller, which can control the start and stop of the fan.

[0032] In use, the yellow tea to be fermented is placed in a basket, and the basket containing the yellow tea is placed on a transfer cart. The sliding door 13 is kept closed, and the transfer cart is pushed into the box 11 through the front anti-collision door 12. The temperature, humidity, and fermentation time inside the box 11 are set by the control device 5. After setting, it is started with one button. The hot and humid air quickly enters the top of the box 11 through the air outlet 201 on the air supply channel 2 and flows downward quickly. The hot and humid air enters the guide cavity 4 through the guide hole 301 at the bottom and flows upward through the slit 7. Under the action of the fan 8, a negative pressure is formed at the top of the guide cavity 4 near the wind baffle 3, so that the hot and humid air at the bottom of the guide cavity 4 continuously flows from the guide hole 301 at the top to the area between the two wind baffles 3. This makes the temperature and humidity inside the box 11 more uniform, thereby improving the fermentation effect of the yellow tea.

[0033] It should be noted that the bottom plate, top plate and side walls of the box 11 are all made of polyurethane insulated sandwich panels. When the anti-collision door 12 and the sliding door 13 are closed, the interior of the box 11 will form a sealed space with a good heat insulation effect.

[0034] It should be noted that the air supply device is existing technology, and its working principle and usage are known, so it will not be described in detail here.

[0035] It should be noted that as the amount of hot and humid gas inside the chamber 11 increases, the internal pressure will gradually increase. When the pressure reaches the preset threshold, the PLC controller will control the solenoid valve 9 to open, so that the gas inside the chamber 11 can be discharged through the exhaust pipe.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
