Description

Technical Field

[0001] The invention relates to the technical field of fermented black bean fermentation equipment, in particular to a fermentation device for light black bean and a fermentation process thereof. Background Art

[0002] Douchi (fermented black beans) is a traditional fermented food originating in China. Made primarily from high-quality soybeans through a process of steaming, inoculation, fermentation, and drying, the soybeans are first steamed. Specific microbial strains (such as molds and bacteria) are then added for temperature-controlled fermentation, typically lasting several days to weeks, until the beans become loose and develop a rich aroma. After fermentation, the fermented black beans are washed and air-dried, becoming a long-lasting condiment. Light black beans are dark brown in color, have a chewy, slightly salty texture, and a unique umami flavor. They are commonly used in a variety of dishes, including steamed fish, stir-fried meats, and stewed vegetables, effectively enhancing the overall flavor. Furthermore, light black beans are rich in protein, B vitamins, and minerals, and possess several health benefits, such as promoting digestion and regulating intestinal flora. With the development of modern culinary culture, light black beans have become popular not only in Chinese cuisine but have also been increasingly adopted by international cuisines, becoming a key ingredient in many creative dishes.

[0003] A Chinese patent discloses a fermentation device for fermented black beans and a fermentation method thereof (authorization announcement number 202411045250.7), which includes a fermentation tank body, a sealing cover plate installed on the top of the fermentation tank body, a stirring structure installed on the fermentation tank body, and an aeration structure installed on the sealing cover plate.

[0004] During the fermentation process of fermented black beans, the temperature inside the black beans will gradually increase. When the temperature is too high, it will affect the fermentation effect of the black beans. The existing solution is to turn the pile over, that is, turn out the black beans inside the pile and turn out the black beans outside the pile, so as to improve the fermentation effect. In addition, the black beans are not easy to clump during the turning process, which improves the fermentation effect. In the above patent, turning the pile is achieved by stirring, but it is impossible to achieve the effect of gradually turning the internal black beans out of the pile. In addition, the stirring structure in the above patent will also cause the black beans to be damaged, resulting in a decrease in the quality of the black beans.

When the driving motor 502 is started, the driving motor 502 drives the driving gear 503 to rotate, and the driving gear 503 drives the rotating cylinder 102 to rotate through the driven gear 501. The rotating cylinder 102 drives multiple triangular boxes 201 to rotate through the inclined cylinder 103. At the same time, the rotating cylinder 102 drives the internal gear 403 to rotate through the circular plate 202. During the rotation of the internal gear 403, the ring gear 404 does not rotate. As a result, when the internal gear 403 rotates, the internal gear 403 is also in a state of self-rotation through the engagement with the ring gear 404. At this time, the internal gear 403 will also drive the second bevel gear 402 to rotate, and the second bevel gear 402 will drive the rotating cylinder 204 to rotate through the first bevel gear 401.

[0027] A fermentation process for light fermented black beans comprises the following steps: Step 1: Select high-quality soybeans, soak them for 12 hours, and then steam them until the beans are completely soft; Step 2: Inoculate the cooked beans with a specific strain of bacteria, usually Aspergillus niger or other fermentation bacteria, which helps the fermentation process of the beans; Step 3: Place the soybeans inoculated with the spawn into the fermentation tank 101 and set the fermentation tank 101 to a suitable temperature, usually around 26 degrees. As the soybeans ferment, they generate heat. The staff regularly monitors the temperature inside the soybean pile. When the temperature inside the soybean pile approaches 37 degrees, the drive motor 502 in the drive assembly 5 is started to turn the soybeans, thereby cooling the pile. Step 4: After fermentation is complete, take out the fermented black beans, wash and dry them, and finally add other spices or seasonings according to taste.

[0028] The working principle of the present invention is: When the present invention is in use, the staff first puts the soybeans that have been steamed and softened and have been inoculated with the fungus into the fermentation tank 101 through the discharge door 109, so that the soybeans fall onto the movable ring plate 107 and wait for the fermented black bean pile to ferment. The staff needs to detect the temperature inside the black bean pile every half an hour. When the temperature reaches 36-37 degrees, the staff starts the drive motor 502. When the drive motor 502 is started, the drive motor 502 drives the drive gear 503 to rotate. The drive gear 503 drives the rotating cylinder 102 to rotate through the driven gear 501. The rotating cylinder 102 drives the multiple triangular boxes 201 to rotate through the inclined cylinder 103. At the same time, the rotating cylinder 102 drives the internal gear 403 to rotate through the circular plate 202. During the rotation of the internal gear 403, the ring gear 404 does not rotate, thereby causing the internal gear 40 During rotation, the internal gear 403 is also in a state of self-rotation due to the meshing with the ring gear 404. At this time, the internal gear 403 also drives the second bevel gear 402 to rotate. The second bevel gear 402 in turn drives the rotating drum 204 to rotate through the first bevel gear 401. The rotating drum 204 drives the first sprocket 205 to rotate, and then the first sprocket 205 drives the second sprocket 206 to rotate through the chain 207. The second sprocket 206 drives the worm gear 209 to rotate through the worm 208. The worm gear 209 drives the horizontal bevel gear 210 to rotate. The horizontal bevel gear 210 drives the vertical bevel gear 211 to rotate. The vertical bevel gear 211 drives the pulley 212 to rotate through the connecting rod 213, so that the pulley 212 can drive the belt 214 to move, and the belt 214 can scrape the fermented black beans on the upper side of the movable ring plate 107 to the upper side of the movable plate 106. At the same time, when the rotating cylinder 102 rotates, it can use the threaded action with the threaded cylinder 108 to drive the threaded cylinder 108 to move downward, and the threaded cylinder 108 drives the movable plate 106 to move downward. At this time, the movable plate 106 pushes the piston 303 downward through the support rod 304. When the piston 303 moves downward, the second air cylinder 302 generates air pressure, and under the air pressure of the first air cylinder 301, it pushes the piston 303 in the first air cylinder 301 to move upward. The piston 303 inside the first air cylinder 301 pushes the movable ring plate 107 upward through the support rod 304, thereby enabling the scraping component 2 to start scraping from the surface of the fermented black bean pile, so that the scraped black bean falls to the fermented black bean pile in the movable plate 106. The innermost fermented black bean is the fermented black bean on the outermost surface of the initial fermented black bean pile, which ultimately improves the fermentation effect of the fermented black bean.
