Description

Technical Field

[0001] This utility model relates to the field of fermented bean curd technology, and in particular to a microbial spraying device for fermenting fermented bean curd blanks. Background Technology

[0002] Fermented bean curd, also known as tofu curd, requires the use of fermented bean curd blocks in its production. The fermentation of these blocks requires the spraying and inoculation of microorganisms.

[0003] A search revealed Chinese Patent Publication No. CN220099008U, which discloses a microbial spraying device for fermenting fermented bean curd. This device, through the cooperation of a sealing plate, a connecting rod, a slider, a spring, and a connecting ring, causes the rotating threaded tube to drive the slider, thereby rotating the sealing plate. This controls whether the microbial inoculum passes through the connecting tube or is blocked, conveniently adjusting the spraying range and reducing microbial waste.

[0004] The aforementioned device has certain drawbacks during use. For example, when there are fermentation tanks of various sizes during the transportation process, the threaded pipe needs to be manually rotated multiple times, which affects the efficiency of the inoculum spraying. Therefore, a microbial inoculum spraying device for fermenting fermented bean curd is proposed to solve the above problems. Utility Model Content

[0030] Reference Figure 2 - Figure 3The top of the C-shaped frame 3 is equipped with an adjustment component 4, which facilitates the adjustment of the spray range on the fermentation box and is suitable for fermentation boxes of different specifications during transportation, thereby improving work efficiency. The adjustment component 4 includes a guide rail 41, with a rack 42 slidably connected inside the guide rail 41. A limiting groove 43 is formed on the bottom surface of the rack 42. A protrusion 44 is fixedly connected inside the guide rail 41 and slidably connected inside the limiting groove 43. The guide rail 41 provides a track for the movement of the rack 42 and supports the rack 42. The rack 42 is positioned by the protrusion 44 and the limiting groove 43, allowing the rack 42 to move laterally along the direction of the protrusion 44, thereby improving the stability of the movement of the protrusion 44.

[0031] Reference Figure 2 - Figure 3 A motor 45 is fixedly connected to the surface of the C-shaped frame 3. The output shaft of the motor 45 passes through and is rotatably connected to the bottom surface of the C-shaped frame 3. A gear 46 is fixedly connected to the output shaft of the motor 45. All gears 46 mesh with racks 42. The motor 45 drives the gears 46 to rotate through its output shaft, thereby realizing the lateral movement of the racks 42. Two sets of guide rails 41 and racks 42 are provided, and the two sets of guide rails 41 and racks 42 are arrayed with the center of rotation of the gears 46 as the center of rotation. All gears 46 mesh with each other. Through the rotation of the gears 46, the two sets of racks 42 move in opposite directions, thereby adjusting the distance between the two sets of racks 42. Two sets of multiple support columns 47 are fixedly connected to the bottom surface of the racks 42. A feeding pipe 48 is fixedly connected to the bottom surface of the support columns 47. Multiple sets of arrayed nozzles 49 are fixedly connected to the bottom surface of the feeding pipe 48. The support column 47 is used to support and fix the feeding pipe 48, so that the nozzle 49 at the bottom of the feeding pipe 48 moves with the movement of the rack 42, thereby controlling the spray range of the nozzle 49.

[0032] Reference Figure 1 - Figure 3A conveying assembly 5 is installed on the side wall of the recycling box 1. The conveying assembly 5 is used to convey and recycle the inoculum, thereby improving the utilization rate of the inoculum. The conveying assembly 5 includes an inoculum box 51, which is fixedly connected to the side wall of the recycling box 1. A water pump 52 is fixedly connected to the surface of the inoculum box 51. One end of the water pump 52 is connected to the inoculum box 51, and the other end of the water pump 52 is fixedly connected to a conveying pipe 53. A diversion pipe 54 is fixedly connected to the end of the conveying pipe 53. Two sets of flexible hoses 55 are fixedly connected to the side wall of the diversion pipe 54. The two sets of flexible hoses 55 are respectively fixedly connected to the ends of two sets of feeding pipes 48. The inoculum box 51 is used to store the inoculum required for fermentation of fermented bean curd. The inoculum liquid inside the inoculum box 51 is extracted by the water pump 52 and simultaneously fed into the two sets of feeding pipes 48 through the conveying pipe 53, diversion pipe 54, and flexible hoses 55. The liquid is then sprayed onto the fermented bean curd by the nozzles 49. A second water pump 56 is fixedly connected to the bottom of the inoculum tank 51. One end of the second water pump 56 is connected to the inoculum tank 51, and the other end of the second water pump 56 is fixedly connected to a recovery pipe 57, which is connected to a recovery tank 1. The second water pump 56 pumps the inoculum liquid recovered inside the recovery tank 1 into the inoculum tank 51 through the recovery pipe 57 for recycling, thereby improving the utilization rate of the inoculum and reducing waste.

[0033] Working Principle: During operation, the fermentation box containing fermented bean curd blanks is first placed on the belt conveyor 2. After the equipment is started, the belt conveyor 2 begins to run, transporting the fermentation box to the bottom of the C-shaped frame 3. At this time, the adjusting component 4 makes corresponding adjustments according to the size and shape of the fermentation box to ensure the uniformity and efficiency of the spraying of the inoculum. The rack 42 of the adjusting component 4 moves laterally under the drive of the motor 45, thereby changing the spray range of the nozzle 49 to adapt to fermentation boxes of different sizes.

[0034] As the fermentation box passes the C-shaped frame 3, the nozzle 49 begins spraying the inoculum. Excess inoculum liquid flows into the recovery tank 1 through the strip-shaped holes 21. The inoculum liquid in the recovery tank 1 is drawn out by the water pump 52 in the conveying assembly 5 and transported through the conveying pipe 53, the diversion pipe 54, and the hose 55 to the feeding pipe 48, where it is sprayed again onto the passing fermented bean curd cakes. In this way, the inoculum is recycled, greatly improving the utilization rate of the inoculum and reducing waste.
