Description

Technical Field

[0001] This utility model relates to the field of fermented bean curd production technology, and in particular to a device for adding soup ingredients in fermented bean curd production. Background Technology

[0002] Fermented bean curd is a condiment made from soybeans through processing, grinding, shaping, culturing, and fermentation. During production, a soup additive device is required to precisely control the fermentation environment and ensure stable flavor and consistent quality.

[0003] Existing patent CN214710172U discloses a broth-adding device for fermented bean curd production, comprising a broth tank and a pressure pump. The pressure pump, located at the top of the broth tank, increases the internal pressure. The broth is distributed to three filling pipes via a distribution tank at the bottom of the broth tank. Each filling pipe has an inner filling pipe at its bottom, which is inserted into the fermented bean curd tank. A filling sleeve is installed on the outside of the fermented bean curd tank to prevent broth splashing during filling. Inside the inner filling pipe, a discharge pipe connects to another filling pipe. A distribution plate with four filling nozzles is located at the bottom of the discharge pipe. These nozzles spray the required broth onto the inner wall of the inner filling pipe, allowing the broth to quickly flow into the fermented bean curd tank. This novel broth-adding device ensures speed without damaging the shape of the fermented bean curd inside the tank and prevents broth dripping, effectively improving factory processing efficiency.

[0004] However, in the aforementioned existing technologies, the existing soup addition devices are not perfect for fermented bean curd production, and cannot add soup in a quantitative manner, which has an adverse effect on the qualification rate of food appearance, keeping it at a low level. Utility Model Content

[0005] The purpose of this utility model is to provide a soup ingredient addition device for fermented bean curd production, which aims to solve the technical problem that existing soup ingredient addition devices for fermented bean curd production are not perfect, cannot add soup ingredient in a quantitative manner, and have an adverse effect on the quality of food appearance, resulting in a lower level of quality.

[0006] To achieve the above objectives, this utility model employs a device for adding soup stock in the production of fermented bean curd, comprising a top cover and an adding cylinder. A feeding pipe is mounted on the top cover via a bracket. A flange and a flow meter are mounted at the outlet of the feeding pipe. A threaded sleeve is rotatably mounted on the inner bottom of the adding cylinder via a bearing. A lifting screw is threaded onto the inner thread of the threaded sleeve. A piston is mounted at one end of the lifting screw, and the piston abuts against the inner wall of the adding cylinder. A limiting element is mounted between the other end of the lifting screw and the adding cylinder. A driven gear is mounted at one end of the threaded sleeve. A mounting box is mounted below the adding cylinder. A driving gear is mounted inside the mounting box via a motor drive. The driving gear meshes with the driven gear, and the driven gear extends into the mounting box. The top cover is threadedly connected to the adding cylinder and covers the top of the adding cylinder.

[0007] The limiting component includes a polygonal rod and a fixing frame. The other end of the lifting screw has a polygonal groove. The polygonal rod is disposed on the fixing frame, which is located below the adding cylinder, and the polygonal rod is inserted into the polygonal groove.

[0008] The number of external teeth of the driven gear is greater than the number of external teeth of the driving gear, and the driving gear is located outside the driven gear.

[0009] The top inner part of the upper cover is provided with a conical guide plate, the bottom of which is connected to the feeding pipe, and the piston has a conical surface adapted to the conical guide plate.

[0010] The outer edge of the top cover is provided with a sealing ring, the outer edge of the adding cylinder is provided with a sealing groove, and the sealing ring abuts against the sealing groove.

[0011] This utility model discloses a soup ingredient addition device for fermented bean curd production. The design utilizes a motor to drive a drive gear, which in turn drives a driven gear and a threaded sleeve to rotate. This causes a lifting screw to slowly move a piston up and down. With the assistance of a flow meter, the outflow of soup ingredient can be accurately measured, enabling quantitative addition and precise control of the amount added. A conical guide plate is installed at the top of the upper cover, with its bottom end connected to the feeding pipe. The piston has a conical surface adapted to the guide plate, ensuring smooth soup ingredient addition and preventing residue. A sealing ring at the outer edge of the upper cover abuts against a sealing groove at the outer edge of the adding cylinder, enhancing the device's sealing performance and ensuring the stability and accuracy of the addition process. This effectively solves existing technical problems and improves the food appearance qualification rate. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-6This utility model provides a device for adding soup stock in the production of fermented bean curd, including a top cover 1 and an adding cylinder 2. A feeding pipe 3 is provided above the top cover 1 via a bracket. A flange 4 and a flow meter 5 are provided at the outlet of the feeding pipe 3. A threaded sleeve 6 is rotatably provided at the bottom of the adding cylinder 2 via a bearing. A lifting screw 7 is threaded inside the threaded sleeve 6. A piston 8 is provided at one end of the lifting screw 7 and abuts against the inner wall of the adding cylinder 2. A limit member is provided between the other end of the lifting screw 7 and the adding cylinder 2. A driven gear 9 is provided at one end of the threaded sleeve 6. An installation box 10 is provided below the adding cylinder 2. A driving gear 12 is provided in the installation box 10 via a motor 11. The driving gear 12 meshes with the driven gear 9 and the driven gear 9 extends into the installation box 10. The top cover 1 is threadedly connected to the adding cylinder 2 and covers the top of the adding cylinder 2.

[0022] In this embodiment, the flange 4 installed at the outlet of the feeding pipe 3 facilitates connection with the fermented bean curd tank, ensuring the stability and sealing of the soup material transportation process and preventing soup material leakage that could lead to waste and environmental pollution. The flow meter 5 accurately measures the flow rate of the soup material through the feeding pipe 3, enabling precise control of the amount of soup material added. This meets the strict requirements for the amount of soup material added during the fermented bean curd production process, effectively avoiding any impact on the quality and taste of the fermented bean curd due to inaccurate addition. The threaded sleeve 6, which is rotatably mounted on the bottom of the feeding cylinder 2 via the bearing, is also present. The lifting screw 7, threaded within the cylinder 2, provides a stable transmission structure for the up-and-down movement of the piston 8. This allows the piston 8 to precisely control the amount of broth discharged from the adding cylinder 2. The piston 8 abuts against the inner wall of the adding cylinder 2, effectively preventing broth residue and ensuring accurate broth addition each time. The limiting component restricts the rotation of the lifting screw 7, ensuring it only performs linear up-and-down movement under the drive of the threaded sleeve 6, further improving the accuracy of the piston 8's movement and thus guaranteeing the precision of broth addition. The upper cover 1 is threadedly connected to and covers the adding cylinder 2. This connection method facilitates disassembly and cleaning of the device's interior while ensuring its airtightness, preventing external impurities from entering the adding cylinder 2 and contaminating the broth. This provides a reliable and precise guarantee for broth addition in fermented bean curd production.

[0023] Furthermore, the limiting member includes a polygonal rod 13 and a fixing frame 14. The other end of the lifting screw 7 has a polygonal groove 15. The polygonal rod 13 is disposed on the fixing frame 14. The fixing frame 14 is disposed below the adding cylinder 2, and the polygonal rod 13 is inserted into the polygonal groove 15.

[0024] In this embodiment, the design structure is simple and stable, which can effectively prevent the lifting screw 7 from rotating as the threaded sleeve 6 rotates, ensuring that the lifting screw 7 can only move up and down in a straight line along the thread direction, thereby ensuring that the piston 8 can accurately control the discharge amount of soup in the adding cylinder 2.

[0025] Furthermore, the number of external teeth of the driven gear 9 is greater than the number of external teeth of the driving gear 12, and the driving gear 12 is located outside the driven gear 9.

[0026] In this embodiment, the gear transmission ratio design allows the driven gear 9 to achieve a significant reduction in rotational speed when the motor 11 drives the driving gear 12. Since the driven gear 9 is connected to the threaded sleeve 6, it drives the threaded sleeve 6 to rotate slowly, resulting in smoother, slower, and more precise movement of the lifting screw 7 and the piston 8. During the addition of broth in the fermented bean curd production process, this smooth and precise movement allows for better control of the broth addition speed and amount, preventing the addition speed from being too fast or too slow and affecting the production process and quality of the fermented bean curd, thus providing strong support for the refined control of fermented bean curd production.

[0027] Furthermore, a conical guide plate 16 is provided on the inner top of the upper cover 1, the bottom of the conical guide plate 16 is connected to the feeding pipe 3, and the piston 8 has a conical surface 17 adapted to the conical guide plate 16.

[0028] In this embodiment, when the piston 8 moves upward, the conical surface 17 can fit tightly with the conical guide plate 16, further preventing soup residue from remaining between the two and ensuring that the soup in the adding cylinder 2 can be completely discharged.

[0029] Furthermore, a sealing ring 18 is provided at the outer edge of the upper cover 1, and a sealing groove 19 is provided at the outer edge of the adding cylinder 2, and the sealing ring 18 abuts against the sealing groove 19.

[0030] In this embodiment, the sealing ring 18 provided at the outer edge of the upper cover 1 abuts against the sealing groove 19 at the outer edge of the adding cylinder 2, forming a reliable sealing barrier.

[0031] When using this utility model, the upper cover 1 is unscrewed by rotating the thread, and an appropriate amount of soup is injected into the adding cylinder 2. Then, the upper cover 1 is put back on the adding cylinder 2. At this time, the sealing ring 18 at the outer edge of the upper cover 1 will tightly abut against the sealing groove 19 at the outer edge of the adding cylinder 2, ensuring that the device is well sealed and preventing soup leakage and external impurities from entering. Next, the motor 11 inside the mounting box 10 is started. The motor 11 drives the drive gear 12 to rotate. Since the drive gear 12 meshes with the driven gear 9 and the driven gear 9 has more external teeth, the driven gear 9 will rotate slowly, thereby driving the threaded sleeve 6 connected to the driven gear 9 to rotate. The rotation of the threaded sleeve 6 causes the lifting screw 7 with its thread set inside to move slowly upward along the inner wall of the adding cylinder 2 under the action of the limiting member. The soup flows out through the adding pipe 3 under pressure. The flow meter 5 set at the outlet of the adding pipe 3 will accurately measure the soup flow rate in real time. When the preset addition amount is reached, the motor 11 is turned off, completing one soup addition operation. During the soup addition process, the conical guide plate 16 on the top of the upper cover 1 will smoothly guide the soup into the adding cylinder 2. The conical surface 17 adapted on the piston 8 can also prevent soup residue and ensure the accuracy of the addition amount.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
