Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a fermented black bean mixing device. Background Technology
[0002] Doubanjiang (fermented black soybeans) is a traditional food made from fermented soybeans. Its production history is long, dating back thousands of years to China, and it is one of China's traditional fermented foods. The brewing process of doubanjiang mainly includes soaking, steaming, koji making, stirring, and fermentation. Among these, the stirring process plays a crucial role in the quality of the finished product, primarily ensuring uniform fermentation of the soybeans. During fermentation, doubanjiang needs to maintain a certain level of humidity and aeration. Stirring helps air circulate between the soybeans, preventing some areas from becoming too moist or lacking oxygen, thus creating a more uniform fermentation environment and ensuring that the fermentation bacteria can multiply evenly throughout the batch. Stirring in doubanjiang production is not only for physical uniformity but also directly affects the fermentation quality, flavor, color, and texture of the soybeans. However, the traditional stirring process, which involves workers stirring with shovels, is not only labor-intensive and involves stirring only a small amount of soybeans at a time, resulting in low stirring efficiency, but it also affects the stirring time, directly impacting the fermentation quality of the doubanjiang. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a fermented black bean mixing device that can reduce the intensity of manual labor and improve the mixing efficiency of soybeans.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A fermented black bean mixing device includes a mixing tank, a guide rail extending around the edge of the mixing tank is installed on the outside of the mixing tank, a trolley is installed on the guide rail and is slidably connected to it and can move along the extension direction of the guide rail, a mixing arm is installed on the trolley and can extend into the mixing tank, a mixing bucket is installed at the front end of the mixing arm, and the mixing arm can drive the mixing bucket to mix the fermented black beans in the mixing tank.
[0006] In this invention, the mixing arm on the mobile trolley controls the mixing bucket to mix the fermented soybeans in the inner mixing tank, using mechanical means to replace manual labor and reduce the intensity of manual labor; the mobile trolley can move around the mixing tank under the guidance of the guide rail, mixing the soybeans in all parts of the mixing tank, which is not only highly efficient, but also makes the mixing effect more uniform.
[0007] As an optimization, the mixing tank has a long, narrow structure. The guide rail includes straight tracks respectively disposed on both sides of the mixing tank along its length. The straight tracks extend parallel to the length of the mixing tank, with both ends extending to both ends of the mixing tank. The two straight tracks are connected at one end on the same side by an arc-shaped track. A baffle for blocking and limiting the movement of the trolley is installed at the other end on the same side. By rationally arranging the width of the mixing tank and the mixing range of the mixing arms, the overall mixing range can be increased by moving the trolley to both sides, thus making efficient use of space.
[0008] As an optimization, the mobile trolley is equipped with a moving device for driving the trolley to move on the guide rail. Controlling the movement of the mobile trolley via this moving device further reduces manual labor intensity.
[0009] As an optimization, position sensors are installed on the side of the mobile trolley to detect the baffles on the two straight tracks. The position sensors are electrically connected to the moving device. When a position sensor detects a corresponding baffle, a displacement sensor outputs a detection signal to the moving device, thereby limiting the movement of the mobile trolley towards the baffle. Although the baffles can block and limit the movement of the mobile trolley, preventing it from accidentally detaching from the track end, the mobile trolley can still collide with the baffles. Such collisions can easily damage the mobile trolley and related equipment within its tilting arm. Therefore, this application uses position sensors to sense the position of the baffles. When the position sensor detects a corresponding baffle, it outputs a signal to the moving device, thereby controlling the mobile trolley to stop moving towards the baffle, thus preventing it from colliding with it.
[0010] As an optimization, a diffuse reflection photoelectric switch capable of detecting the mixing tank is installed on the side of the mobile trolley facing the mixing tank. The diffuse reflection photoelectric switch is connected in series in the power supply circuit of the mobile device. When the diffuse reflection photoelectric switch detects the mixing tank, it is in a closed state; when it does not detect the mixing tank, it is in an open state. Throughout the entire mixing process, the mobile trolley moves on the guide rail, and the diffuse reflection photoelectric switch on the trolley continuously detects the mixing tank. Only when the mixing tank is detected is the diffuse reflection photoelectric switch in a closed state, allowing the mobile device to be powered on and control the movement of the mobile trolley. If the diffuse reflection photoelectric switch fails to detect the mixing tank, it indicates that the mobile trolley may have derailed, thus disconnecting the power supply circuit of the mobile device and preventing the mobile trolley from moving further, avoiding a more serious accident.
[0011] As an optimization, a flexible shovel plate is provided at the front edge of the mixing bucket. The flexible shovel plate extends along the extension direction of the front edge of the mixing bucket, and its side facing the mixing bucket is fixedly connected to the front edge of the mixing bucket, so that the upper surface of the flexible shovel plate is in contact with the inner side of the front edge of the mixing bucket. The mixing arm controls the start of the mixing bucket's mixing action. The flexible shovel plate at the front can first contact the bottom of the mixing tank. Its flexible structure can undergo a certain degree of deformation, which not only avoids damage to the bottom of the tank, but also, in conjunction with the "shoveling" operation, better shovels the beans located at the bottom of the tank into the bucket, ensuring that the beans at the bottom are not left unmixed, thereby improving the uniformity of mixing.
[0012] As an optimization, a connector is provided between the mixing arm and the mixing bucket. The connector includes two flanges that are opposite each other and spaced apart. Multiple connecting bolts are evenly spaced between the two flanges along their center lines. The threaded section of the connecting bolt passes through the two flanges parallel to their center lines and can slide with them. A connecting nut is threaded onto the end of the threaded section of the connecting bolt away from the bolt head. The connecting nut abuts against the flange on its side. A buffer spring is fitted onto the threaded section of the connecting bolt between the two flanges. The two ends of the buffer spring abut against the two flanges respectively. Connecting heads are fixedly connected to opposite sides of each of the two flanges, and each flange is fixedly connected to the mixing arm and the mixing bucket via the connecting heads. When the mixing bucket is used to mix the beans at the bottom of the mixing tank, the front end of the flexible shovel plate will contact the bottom of the tank. Although the flexible shovel plate can undergo some deformation and buffering, if the force is not properly controlled, it can still damage the mixing tank. In this application, when the mixing bucket reaches the bottom of the mixing tank, the force exerted by the mixing bucket on the mixing arm and the force exerted by the mixing arm on the mixing bucket will act on the two flanges respectively, thereby compressing the buffer spring. The two flanges move in opposite directions, and the damage to the mixing tank is reduced through the compression between the two flanges.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention replaces the traditional manual mixing method with mechanized equipment, which can significantly improve the mixing efficiency; reduce the labor intensity of workers, improve production efficiency, and avoid the physical burden caused by the traditional hand-held shovel mixing method; the equipment can process more beans in a short time, avoiding the problems of small mixing volume and uneven mixing in the manual operation process.
