Description

Technical Field

[0001] This utility model belongs to the field of preservative production, processing and mixing technology, and specifically relates to a mixing device for making pastry preservatives. Background Technology

[0002] In the food industry, pastries are a popular food category, and maintaining their shelf life and quality is crucial. Pastry preservatives have emerged to address this need, effectively extending the shelf life of pastries and preserving their quality and freshness. For example, acidic preservatives like potassium sorbate inhibit the activity of molds, yeasts, and aerobic bacteria, preventing spoilage. Calcium propionate has a strong inhibitory effect on molds, aerobic spores, and Gram-negative bacteria, delaying mold growth. Sodium dehydroacetate has broad-spectrum antibacterial capabilities, inhibiting various spoilage bacteria and molds, ensuring the taste and texture of pastries. Sodium diacetate not only prevents spoilage but also improves the flavor of pastries. However, the usage of these preservatives must strictly adhere to relevant national standards to ensure food safety.

[0003] In the production process of preservatives, the performance of the mixing device affects the product quality. For example, the mixing device for fruit preservative processing disclosed in Chinese Patent No. CN210131559U has certain advantages. The device is equipped with a mixing tank, the top feeding hopper is connected to the feeding port of the mixing tank, the bottom support legs play a stabilizing role, the discharge hopper is connected to the discharge port, and the top is also equipped with a spray pipe and nozzle, which can realize cleaning without stopping the machine, reduce the labor intensity of workers, and does not affect subsequent processing. In addition, it can reduce mixing noise, improve the safety of use, and facilitate real-time observation of the mixing status of materials.

[0004] However, the device has obvious defects in practical applications. Its stirring function focuses on the horizontal direction and lacks efficient vertical mixing ability. During the stirring process, it cannot transport the material at the bottom of the tank to the top, making it difficult to achieve uniform vertical mixing inside the tank. The mixing effect is poor and it is difficult to meet the production requirements for efficient and uniform mixing of preservatives. It is evident that the existing technology has certain defects and shortcomings, so it needs to be improved and designed. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a stirring device for making pastry preservatives, so as to solve the problem that the existing technology cannot efficiently mix and stir from top to bottom during application.

[0010] As a preferred technical solution, the lower inner side of the card holder is provided with a limiting hole, and the end of the mounting screw is inserted into the inner side of the limiting hole. The mounting screw is a hand-tightening screw.

[0011] As a preferred technical solution, a feed valve is fixedly installed on one side of the top of the top cover, the output end of the feed valve passes through the top cover, and a guide hopper is fixedly installed on the input end of the feed valve.

[0012] As a preferred technical solution, the cleaning assembly includes an annular tube, which is fixedly installed at the bottom of the top cover. Water spray pipes are fixedly installed at equal intervals at the bottom of the annular tube. A water receiving pipe is fixedly installed at the input end of the annular tube, and a connecting flange is fixedly installed at the outer end of the water receiving pipe through the top cover.

[0013] As a preferred technical solution, the stirring assembly includes a rotating shaft, which is fixedly installed at the bottom output end of the drive motor.

Detailed Implementation

[0023] Example

[0024] refer to Figures 1 to 4 A stirring device for making pastry preservatives according to this embodiment includes a mounting frame 1, a mounting ring 2 fixedly mounted on the top of the mounting frame 1, a tank 3 fixedly mounted on the inner side of the mounting ring 2, a stirring mechanism 6 provided on the top of the tank 3, the bottom of the stirring mechanism 6 extending into the interior of the tank 3, a circulation group 5 fixedly mounted on the bottom of the tank 3, and a discharge valve 4 fixedly connected to the bottom of the circulation group 5.

[0025] The stirring mechanism 6 includes a top cover 61, with a mounting piece 62 on the outer side of the top cover 61. The top cover 61 is mounted on the top of the tank 3 via the mounting piece 62. A drive motor 63 is fixedly mounted in the middle of the top of the top cover 61. A stirring assembly 64 is fixedly mounted through the top cover 61 at the output end of the drive motor 63. The main body of the stirring assembly 64 is inserted inside the tank 3, and the bottom of the stirring assembly 64 is inserted inside the circulation group 5. A cleaning assembly 65 is fixedly mounted at the bottom of the top cover 61. This stirring device, used for making pastry preservatives, operates by having the drive motor 63 mounted on the top of the top cover 61. After starting, its output end drives the connected stirring assembly 64 to rotate at high speed. The main body of the stirring assembly 64 is located inside the tank 3. By rotating at high speed, it stirs and mixes the raw materials for making pastry preservatives inside the tank. It is mounted on the mounting frame. The mounting ring 2 at the top firmly supports the tank body 3, ensuring the stability of the mixing process. During the mixing process, the bottom of the mixing component 64 is connected to the circulation group 5, driving the circulation group 5 to work. The circulation group 5 pumps the raw materials at the bottom of the tank, realizing the circulation flow of materials and further improving the uniformity of mixing. When it is necessary to clean the inside of the tank body 3, the cleaning component 65 installed at the bottom of the top cover 61 plays a role in flushing the inner wall of the tank body 3 and residual materials. In addition, the top cover 61 is firmly installed on the top of the tank body 3 through the outer mounting part 62, which makes it easy to disassemble and install the top cover 61 and the mixing component 64 before and after the mixing operation, so as to facilitate the maintenance, repair and addition of raw materials. The discharge valve 4 at the bottom of the tank body 3 is opened after the mixing is completed to discharge the prepared pastry preservative.

[0026] refer to Figures 1-4 The mounting component 62 includes a mounting base 621, which is fixedly installed on the upper part of the outer surface of the tank body 3 in a ring-shaped arrangement with equal spacing. A mounting plate 622 is inserted inside the mounting base 621, and a mounting screw 623 is threaded to the lower end of the mounting plate 622. The end of the mounting screw 623 passes through the mounting plate 622. Limiting holes 624 are opened on the lower inner side of the mounting base 621, and the end of the mounting screw 623 is inserted into the inner side of the limiting holes 624. The mounting screw 623 is a hand-tightening screw. A feed valve 7 is fixedly installed on one side of the top of the top cover 61. The output end of the feed valve 7 passes through the top cover 61, and a guide bucket 8 is fixedly installed on the input end of the feed valve 7. The mounting base 621 is installed in a ring-shaped arrangement with equal spacing to provide basic support for the installation. During installation, the mounting plate 622 is inserted. Inside the mounting bracket 621, a hand-tightening mounting screw 623 is then screwed into the lower end of the mounting plate 622 via a threaded connection. Since the end of the mounting screw 623 penetrates the mounting plate 622, the depth of its insertion into the lower limit hole 624 inside the mounting bracket 621 can be adjusted during the tightening process. When the end of the mounting screw 623 is precisely inserted into the limit hole 624, the mounting plate 622 can be firmly fixed on the mounting bracket 621, thereby making the top cover 61 stably installed on the top of the tank 3. When adding the raw materials for making pastry preservatives, the feed valve 7 on one side of the top of the top cover 61 is opened. The material passes through the guide bucket 8 connected to the input end of the feed valve 7 and smoothly enters the tank 3 through the output end of the feed valve 7 under the guidance of the guide bucket 8, thus preparing for the subsequent stirring operation.

[0027] refer to Figures 3-4 The cleaning assembly 65 includes an annular pipe 651, which is fixedly installed at the bottom of the top cover 61. Water spray pipes 652 are fixedly installed at equal intervals at the bottom of the annular pipe 651. A water receiving pipe 653 is fixedly installed at the input end of the annular pipe 651. A connecting flange 654 is fixedly installed at the outer end of the water receiving pipe 653, penetrating the top cover 61. During use, when cleaning of the inside of the tank 3 is required, an external water source is connected to the water receiving pipe 653 via the connecting flange 654. Water from the external source flows through the connecting flange 654 into the water receiving pipe 653, which functions as a water delivery channel. The water is smoothly delivered to the annular pipe 651 fixedly installed at the bottom of the top cover 61. After the annular pipe 651 collects the water, the water is sprayed evenly into the tank 3 using the water spray pipes 652 fixedly installed at equal intervals at the bottom. The water spray pipes 652 are distributed at specific angles and intervals, so that the sprayed water can cover all areas inside the tank 3, thoroughly washing the inner wall of the tank 3 and the residual pastry preservative raw materials, thereby achieving efficient cleaning of the inside of the tank 3, ensuring the cleanliness and hygiene of the stirring device, and providing a good environment for the subsequent production of pastry preservatives.

[0028] refer to Figures 1-4 The stirring assembly 64 includes a rotating shaft 641, which is fixedly installed at the bottom output end of the drive motor 63. Stirring side supports 642 are fixedly installed in a ring at equal intervals on the upper surface of the outer surface of the rotating shaft 641. Stirring inner rods 643 are fixedly installed at equal intervals on the inner side of the stirring side supports 642. A stirring auger 644 is fixedly installed at the bottom of the rotating shaft 641 and inserted into the circulation group 5. The circulation group 5 includes a discharge hopper 51, which is fixedly installed at the bottom of the tank 3. A discharge valve 4 is fixedly installed at the bottom center of the discharge hopper 51. Return valves are fixedly installed at equal intervals on the outer side of the discharge hopper 51. Pipe 52, the output end of return pipe 52 is connected to the upper end of the interior of tank 3. Agitator 644 is inserted inside discharge hopper 51. The upper end of discharge hopper 51 is an inverted cone shape, and the lower end is cylindrical. The upper end of agitator 644 is also conical to match discharge hopper 51, and the lower end is cylindrical to match the interior of discharge hopper 51. When the agitator is running, it is started by drive motor 63, which drives the fixed rotating shaft 641 to rotate at high speed. The upper surface of the rotating shaft 641 has a ring of agitators arranged at equal intervals. The side frame 642 and the inner stirring rods 643, which are equally spaced and installed on the inner side of the stirring side frame 642, rotate together with the rotating shaft 641. Inside the tank 3, they perform preliminary stirring and mixing of the raw materials for making the pastry preservative, so that the materials are initially blended in the horizontal direction. At the same time, the stirring auger 644 fixed at the bottom of the rotating shaft 641 also starts to work. Because the upper end of the stirring auger 644 is conical and the lower end is cylindrical and fits the inside of the discharge hopper 51, and is inserted into the discharge hopper 51 which has an inverted conical upper end and a cylindrical lower end, when the stirring auger 644 rotates, the discharge hopper 51 can guide the material to flow towards the stirring. During the rotation of the auger 644, the material in the discharge hopper 51 is first pushed downwards by its special shape and the pumping force generated by its rotation. Then, the material is transported upwards back to the top of the tank 3 through the return pipe 52, which is fixed at equal intervals on the outside of the discharge hopper 51 and whose output end is connected to the upper part of the tank 3. In this way, the material forms an up-and-down circulation within the tank 3. With the continuous stirring of the stirring side frame 642 and the stirring inner rod 643, the stirring and mixing of the material is promoted in an all-round and deep manner. After the stirring is completed, the discharge valve 4, which is fixedly installed in the middle of the bottom of the discharge hopper 51, is opened, and the finished product of the preservative can be discharged.

[0029] Operating principle and advantages: This device greatly improves operational efficiency by incorporating a stirring mechanism 6. When the device is put into use, the drive motor 63 is started, and the power generated by the drive motor 63 is transmitted to the rotating shaft 641, causing the shaft 641 to rotate. As the shaft 641 rotates, the connected stirring side frame 642 and stirring inner rod 643 rotate synchronously. Both rotate at high speed inside the tank 3, providing the basic power for efficient mixing of raw materials and initially realizing the stirring operation of raw materials. During the stirring process, the rotation of the rotating shaft 641 drives the stirring auger 6 at its bottom. As 44 rotates, the agitator 644, with its special structural design, plays a role in promoting the flow of raw materials during rotation. First, it causes the raw materials to flow downwards, and then, through the pumping principle, it transports the raw materials upwards through the return pipe 52. The return pipe 52 guides the bottom solution back to the top of the tank 3, so that the liquid at the bottom and top of the tank 3 forms an up-and-down circulation. On this basis, combined with the continuous rotation and stirring of the agitator side frame 642 and the agitator inner rod 643, the mixing of raw materials is promoted in an all-round and deep way, which significantly improves the mixing effect.

[0030] When this device requires cleaning and maintenance, the external water supply pipe can be connected to the water receiving pipe 653 via the connecting flange 654. The external water supply pipe supplies water to the water receiving pipe 653, which plays an auxiliary role in guiding the water and smoothly transporting it into the annular pipe 651. The annular pipe 651 then further discharges the water precisely into a specific groove on the inner wall of the tank 3 through the spray pipe 652. At this time, the drive motor 63 is restarted to drive the stirring side frame 642 and the stirring inner rod 643 to stir. At the same time, the stirring auger 644 drives the cleaning fluid to circulate between the tank 3 and the return pipe 52. Under this series of synergistic effects, the water inside the tank 3 forms a violent up-and-down circulating state, which thoroughly and intensely flushes every corner of the tank 3, providing an excellent cleaning effect and significantly improving the convenience and efficiency of subsequent cleaning and maintenance work.

[0031] Furthermore, the structural design of this device fully considers the convenience of operation and maintenance. By setting up the mounting component 62, when the equipment is started, the top cover 61 is placed over the top of the tank 3. Then, the mounting screw 623 is twisted to displace it and precisely insert it into the limiting hole 624. Relying on the limiting effect formed by the mutual insertion of the mounting screw 623 and the limiting hole 624, the top cover 61 is securely installed on the top of the tank 3. During the addition of preservative raw materials, the feed valve 7 is opened, and with the auxiliary guiding function of the guide hopper 8, the preservative raw materials can be smoothly and accurately discharged into the tank 3. During the mixing stage… Closing the feed valve 7 enables closed-loop mixing, effectively preventing external impurities from entering and ensuring the purity and efficiency of the mixing process. After the equipment completes the mixing operation, simply open the discharge valve 4 to smoothly discharge the mixed raw materials. When it is necessary to remove the top cover 61 and the bottom mixing component 64 to carry out detailed and in-depth cleaning and maintenance work on the tank body 3 and the mixing mechanism 6, the top cover 61 can be easily removed from the top of the tank body 3 by twisting the installation screw 623 to disengage it from the limiting hole 624, and then the entire mixing mechanism 6 can be removed from the top of the tank body 3 for easy inspection, maintenance and cleaning.
