[0001] This utility model relates to the field of mixer technology, specifically a raw material mixer for preparing vinegar from fermented grains. Background Technology

[0002] Zhaopo vinegar is a traditional snack in Puqian Town, Wenchang City, Hainan Province. It uses the sour vinegar produced by fermenting the lees generated during the brewing process as a soup base. In its preparation, the soup base needs to be pre-processed. Then, the soup base needs to be mixed with various ingredients and steamed.

[0003] Chinese utility model patent application number 202222061235.4 provides a raw material mixer for the preparation of vinegar made from lees. By installing a feeding mechanism, the internal hot air can be blocked when adding ingredients, preventing hot air from shooting upward and causing harm to the operators. At the same time, the double-layer sealing of the sealing cover and sealing plate can increase the heat insulation effect.

[0004] However, during the use of the above equipment, it was found that the feeding mechanism was fixed to the tank, making it difficult to replace the feeding mechanism when using different raw materials. At the same time, the sealing plate, sealing ring, electric push rod connector and other parts of the feeding mechanism are vulnerable parts that need to be replaced regularly after long-term use. However, the fixed structure means that the connection between the tank and the feeding mechanism needs to be disassembled when replacing them, or even the entire equipment needs to be disassembled, which is complicated and time-consuming. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material mixer for preparing vinegar from fermented grains, which solves the problem mentioned in the background technology that makes it difficult to disassemble and replace the feeding mechanism due to the fixed structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example 1:

[0024] Please see Figures 1-4 This utility model provides a raw material mixer for preparing vinegar from fermented grains, including a mixing tank 1. The top of the mixing tank 1 is connected to a top cover 2 via a connecting component 4. A feeding component 3 is provided on the top cover 2. The feeding component 3 includes an L-shaped feeding pipe 31 and a storage tank 32. A conveying pipe 33 is connected to the bottom of the storage tank 32. A second mounting ring 331 is fixedly installed on the conveying pipe 33. Mounting grooves 332 are opened on both sides of the second mounting ring 331. A first mounting ring 311 is fixedly installed on the feeding pipe 31. Rotating grooves 312 are opened on both sides of the first mounting ring 311. A screw rod 313 is rotatably installed in the rotating groove 312. The screw rod 313 is engaged in the mounting groove 332. A fixing nut 314 is screwed onto the screw rod 313.

[0025] The storage tank 32 is a transparent tank, and a scale 322 is provided on the storage tank 32.

[0026] The top of the storage tank 32 is screwed with a sealing cap 321;

[0027] A semi-circular feed port 316 is provided on the feed end of the feed pipe 31, and a semi-circular baffle 317 is rotatably installed on the inner side of the feed port 316.

[0028] A clamping pipe 334 is fixedly installed on the discharge end of the conveying pipe 33, and the clamping pipe 334 is adapted to the inlet 316.

[0029] A connecting ring 315 is fixedly provided on the first mounting ring 311, and a connecting groove 333 is provided on the second mounting ring 331. The connecting groove 333 is adapted to the connecting ring 315, and a sealing ring is embedded in the connecting groove 333.

[0030] A motor 24 is installed on the top cover 2. The output end of the motor 24 is connected to a rotating shaft 21. The rotating shaft 21 is connected to the stirring shaft 22 through a flange. A stirrer 23 is installed on the stirring shaft 22 by bolts.

[0031] Specifically, the replacement of vulnerable parts is achieved through the cooperation of the first mounting ring 311, the second mounting ring 331, the screw rod 313, and the fixing nut 314. The screw rod 313, which is rotatably installed in the rotating grooves 312 on both sides of the first mounting ring 311, is engaged in the mounting groove 332 of the second mounting ring 331. After tightening the fixing nut 314 on the screw rod 313, the conveying pipe 33 and the feeding pipe 31 are securely connected. When the vulnerable parts related to the sealing on the conveying pipe 33, the storage tank 32, or the feeding pipe 31 need to be replaced, simply loosen the fixing nut 314 and rotate the screw rod 313 to disengage it from the mounting groove 332 to separate the conveying pipe 33 from the feeding pipe 31. There is no need to disassemble the overall connection between the tank and the feeding mechanism. The vulnerable parts can be replaced or maintained separately, which reduces the complexity of maintenance operations, shortens equipment downtime, reduces maintenance costs, and avoids the damage to other parts caused by overall disassembly.

[0032] During the replacement of storage tank 32, when the conveying pipe 33 separates from the feed pipe 31, and the clamping pipe 334 of the conveying pipe 33 disengages from the feed inlet 316, the baffle 317 rotates naturally under gravity, completely closing the feed inlet 316. This effectively prevents hot air and steam inside the mixing tank 1 from overflowing back through the feed pipe 31, avoiding burns to workers during the replacement of storage tank 32 and ensuring operational safety. Simultaneously, the closure of the feed inlet 316 reduces heat loss from the mixing tank 1, helping to maintain a stable internal temperature, ensuring the raw material mixing environment remains unaffected, and guaranteeing the continuity and stability of the mixing process.

[0033] The storage tank 32 features a transparent design, and combined with the graduated scale 322, it provides a precise reference for the amount of raw materials added. When adding raw materials, the amount can be visually controlled according to the scale 322, ensuring that the input of raw materials for each batch meets the process formula requirements. This reduces the imbalance of raw material ratios caused by manual estimation errors, thereby guaranteeing the stability of the flavor and quality of the vinegar made from fermented grains. Furthermore, the graduated scale 322 clearly shows the rate of raw material consumption, facilitating advance planning for raw material replacement and avoiding production stoppages due to raw material shortages.

[0034] The connecting ring 315 is fixed on the first mounting ring 311, and the connecting groove 333 is formed on the second mounting ring 331. The connecting ring 315 and the connecting groove 333 are precisely fitted together. During assembly, the connecting ring 315 is embedded in the connecting groove 333 to form a preliminary sealing structure. The sealing ring embedded in the connecting groove 333 further fills the gaps, enhances the sealing effect, prevents steam and hot air from escaping from the mixing tank 1, avoids heat loss affecting mixing efficiency, and protects the workers from heat damage.

[0035] The rotating shaft 21 and the stirring shaft 22 are connected by a flange. The flange connection ensures that the power of the rotating shaft 21 is accurately transmitted to the stirring shaft 22, reducing energy loss during the transmission process. When maintenance is required on the stirring shaft 22 or the stirring components below, the flange connection facilitates quick disassembly and separation of the rotating shaft 21 and the stirring shaft 22, simplifying the maintenance operation process.

[0036] Working principle: Open the sealing cap 321 at the top of the storage tank 32. According to the process formula requirements, accurately add the required raw materials through the scale 322 on the transparent storage tank 32. After adding, tighten the sealing cap 321. Then, align the clamping pipe 334 at the discharge end of the conveying pipe 33 with the semi-circular inlet 316 of the inlet pipe 31, so that the connecting ring 315 on the first mounting ring 311 is embedded in the connecting groove 333 of the second mounting ring 331, ensuring that the sealing ring fits tightly. Rotate the screw rod 313 in the rotating groove 312 on both sides of the first mounting ring 311, so that it is engaged in the mounting groove 332 of the second mounting ring 331. Tighten the fixing nut 314 on the screw rod 313 to complete the tight connection between the conveying pipe 33 and the inlet pipe 31. At this time, the clamping pipe 334 pushes open the semi-circular baffle 317 inside the inlet 316, forming a smooth raw material conveying channel.

[0037] The top cover 2 is connected and fixed to the top of the mixing tank 1 by the connecting component 4. The motor 24 on the top cover 2 is started. The motor 24 drives the stirring shaft 22 to rotate through the output shaft 21. The stirring shaft 22 drives the stirrer 23 to rotate inside the mixing tank 1. At this time, the electric push rod on the control conveying pipe 33 opens the sealing plate, causing the raw material in the storage tank 32 to enter the feed pipe 31 through the conveying pipe 33, the clamping pipe 334 and the feed port 316, and finally flow into the mixing tank 1. During the process, the remaining amount of raw material is observed through the transparent storage tank 32. The raw material consumption rate is monitored by the scale 322, and raw material is replenished in time to maintain continuous mixing.

[0038] When it is necessary to change the type of raw material, first loosen the fixing nut 314 on the screw rod 313, rotate the screw rod 313 to disengage it from the mounting groove 332, and separate the conveying pipe 33 from the feed pipe 31. At this time, the semi-circular baffle 317 inside the feed port 316 will close naturally under the action of gravity, preventing the hot air and steam in the mixing tank 1 from escaping. Remove the original storage tank 32 and replace it with a storage tank 32 containing the new raw material. Repeat the assembly steps to reconnect the conveying pipe 33 and the feed pipe 31. After the baffle 317 is pushed open by the clamping pipe 334, the raw material conveying is restored, and the mixing operation continues.
