Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a constant temperature and humidity drying room for the fermentation of Fu brick tea, such as... Figures 1-5As shown, the constant temperature and humidity drying room for fermenting Fu brick tea includes a drying room 1. A partition plate 2 is fixedly connected inside the drying room 1. A drying mechanism is fixedly connected to the upper surface of the drying room 1. A door 3 is hinged to the front of the drying room 1. A groove A is provided at the bottom and top of the front of the door 3. A heat dissipation plate 4 is fixedly connected inside the groove A. An opening and closing mechanism is fixedly connected to the middle of the front of the door 3.
[0027] The opening and closing mechanism includes an electric push rod 5. One end of the electric push rod 5 is fixedly connected to the front of the door 3, and the other end of the electric push rod 5 is fixedly connected to a connecting block 6. One end of the connecting block 6 is fixedly connected to a baffle plate 7. A slider 8 is fixedly connected to one side of the baffle plate 7. A sliding groove plate 9 is slidably connected to the outer surface of the slider 8. The back of the sliding groove plate 9 is fixedly connected to one side of the front of the door 3. The opening and closing mechanism can quickly adjust the size of the ventilation opening in case of emergencies (such as changes in external temperature, equipment failure, etc.). By adjusting the ventilation opening, it can be ensured that each batch of tea receives uniform fermentation conditions, preventing quality differences caused by uneven environment. The rapid opening and closing of the ventilation opening can effectively cope with changes in ambient temperature and humidity, ensuring that the temperature and humidity are always within a suitable range (such as 25-30℃ and 70%-90% relative humidity) during the fermentation process.
[0028] The drying mechanism includes a box body 10, the bottom of which is fixedly connected to the upper surface of the drying chamber 1. A drive motor 11 is fixedly connected to the front of the box body 10, and a fan 12 is splinedly connected to the output end of the drive motor 11. The Fu brick tea is placed on the placement plate 15, and the drying mechanism adds heat to the placement plate 15. The heat can be blown evenly onto the Fu brick tea through the air outlet to dry the Fu brick tea. Even drying ensures that the moisture in the Fu brick tea is removed evenly, reducing the risk of mold and bacteria growth and extending the shelf life of the Fu brick tea.
[0029] A heating plate 13 is fixedly connected inside the box body 10. An air outlet is opened on the back of the box body 10. An air outlet pipe 14 is fixedly connected inside the air outlet. When the heating plate 13 and the drive motor 11 are started, the drive motor 11 drives the fan 12 to rotate. The fan 12 blows air inside the box body 10, blows warm air through the heating plate 13, and blows the warm air out from the air outlet pipe 14.
[0030] Both sides of the partition plate 2 are fixedly connected to a placement plate 15. The surface of the placement plate 15 has a B groove, and the inside of the B groove is fixedly connected to an air-permeable plate 16. There are several placement plates 15. The Fu brick tea is placed on the placement plate 15. The surface of the placement plate 15 has an air-permeable plate 16, and the surface of the air-permeable plate 16 has an air outlet. The warm air blown from the air outlet pipe 14 can pass through these air outlets and be evenly blown on the Fu brick tea to achieve uniform drying. This uniform drying method not only ensures that the moisture in the Fu brick tea is removed evenly, reduces the risk of mold and bacteria growth, and extends the shelf life of the Fu brick tea, but also makes the Fu brick tea heat evenly during the fermentation process, which helps to improve the unique flavor and aroma quality of the Fu brick tea, and gives it a greater advantage in the subsequent storage and sales stages.
[0031] The inner wall of the drying room 1 is fixedly connected with an insulation layer, and the surface of the insulation layer is coated with a waterproof layer. The insulation layer can maintain a large temperature difference in the drying room 1, which is conducive to maintaining a constant temperature. The waterproof layer plays a waterproof role, preventing moisture from seeping into the wall panels of the drying room 1, which would cause the drying room 1 to be too humid and affect the development of the Fu brick tea.
[0032] A handle 17 is fixedly connected to the bottom of the front of the door 3. The surface of the handle 17 is provided with anti-slip grooves. In actual operation, when the handle 17 is pulled by hand, the drying room 1 can be opened or closed easily. The anti-slip groove design increases the friction between the hand and the handle. Even if the hand is wet or sweaty, it can ensure that the operator will not easily slip when pulling the handle, which greatly improves the convenience and safety of operation.
[0033] Specifically, pull handle 17 to open the drying chamber 1, place the Fu brick tea on the placement plate 15. The surface of the placement plate 15 has a perforated plate 16 with air outlets. Start the heating plate 13 and drive motor 11. The drive motor 11 drives the fan 12 to rotate, and the fan 12 blows air inside the box 10. The heating plate 13 blows warm air, which is then blown out from the air outlet 14 and onto the placement plate 15. The warm air is then blown onto the Fu brick tea through the perforated plate 16, drying it evenly. Even drying ensures that the moisture in the Fu brick tea is removed evenly, reducing the risk of mold and bacterial growth and extending the shelf life of the Fu brick tea. Evenly dried tea is easier to handle in subsequent processing stages such as cutting and packaging, improving overall production efficiency. In subsequent testing, even drying can... To make quality monitoring data more reliable and facilitate problem detection and adjustment, the temperature and humidity inside the drying room 1 are kept constant. Warm air is emitted from the heat dissipation plate 4. In case of emergencies (such as changes in external temperature or equipment failure), the electric push rod 5 is activated. When the electric push rod 5 extends and retracts, it can move the connecting block 6. The connecting block 6 moves the baffle plate 7 up and down. The baffle plate 7 moves within the slide plate 9 via the slider 8. When the baffle plate 7 moves up and down, it can block the heat dissipation plate 4. The size of the ventilation opening is adjusted to a suitable size. The size of the ventilation opening is quickly adjusted. By adjusting the ventilation opening, it can be ensured that each batch of tea receives uniform fermentation conditions, preventing quality differences caused by uneven environment. The rapid opening and closing of the ventilation opening can effectively cope with changes in ambient temperature and humidity, ensuring that the temperature and humidity are always within a suitable range during the fermentation process.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
