Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, specifically a stirring device. Background Technology

[0002] As living standards improve, the demand for food variety and quality is also increasing, providing ample room for development for the food machinery industry. While domestic products are highly competitive in terms of cost-effectiveness for products like horizontal mixing pans, breakthroughs are still needed in core technologies and key performance indicators. This necessitates product development from an innovative perspective and with a focus on independent intellectual property rights to drive technological upgrades.

[0003] The "JB / T 4389-2011 Food Mixer Industry Standard" stipulates that the minimum gap between the mixing device and the inner wall of the mixing bowl should be 5-15mm. However, when mixing complex materials (such as high-viscosity fillings), these gaps can cause the filling to adhere to the inner wall of the mixing bowl. As the heating temperature rises or remains high, this can lead to crusting, scorching, or even the filling becoming an integral part of the bowl wall and difficult to separate. Therefore, currently available mixing devices used by manufacturers, such as... Figure 1 and Figure 2 As shown, the device includes a horizontal mixing tank with a main shaft inserted inside. Several stirring rods are connected to the main shaft, and each stirring rod is connected to a scraper, attempting to scrape the material with minimal gaps. While this represents an improvement, it still does not achieve the desired effect. Furthermore, existing scrapers, such as... Figure 3 As shown, the scraping contact surface is a symmetrical arc surface, and there is still a large gap between it and the inner wall of the barrel when scraping. Utility Model Content

[0004] To address the problems of existing technologies, this invention provides a stirring device that increases the flexibility of the scraper and improves its contact surface. This allows the scraper to theoretically fit seamlessly against the inner wall of the container during stirring, solving the problems of burning, sticking, and crusting when mixing and heating high-viscosity fillings in a horizontal mixing pot. This ensures the nutritional value, safety, and original flavor of the product, avoids rework or scrapping of burnt fillings, simplifies equipment cleaning, and significantly improves production efficiency.

[0005] This utility model provides a stirring device, including a horizontal stirring pot body with a main shaft inserted inside, and a plurality of stirring rod seats connected on the circumference of the main shaft. Each stirring rod seat is connected to a scraper plate through a support rod. The device is characterized in that: the stirring rod seat and the support rod are connected by a rotating joint, and a locking device is provided on the rotating joint; the scraping contact surface of the scraper plate is an asymmetrical arc surface structure.

[0006] In a further improvement, the locking device is a locking screw and a nut.

[0007] In a further improvement, the included angle θ between the side of the scraper and the axis of the stirring rod seat is 30° to 50°.

[0008] The beneficial effects of this utility model are as follows: it increases the flexibility of the scraper and improves the contact surface of the scraper, so that the scraper can theoretically fit seamlessly with the inner wall of the bucket when the mixing device is stirring. This can solve the problems of burning, sticking, and crusting when mixing and heating high-viscosity fillings in a horizontal mixing pot, ensuring the nutritional quality, safety, and original flavor of the product, avoiding rework or scrapping of burnt fillings, and making equipment cleaning easier and significantly improving production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0019] Currently, the mixing devices used by existing manufacturers are such as Figure 1 and Figure 2 As shown, the apparatus includes a horizontal mixing tank body 1 with a main shaft inserted inside. Several mixing rods 2 are connected to the main shaft, and each mixing rod is connected to a scraper 3. The angle between the side of the scraper and the axis of the mixing rod is β, attempting to scrape the material with minimal gap. While this provides some improvement, it still does not achieve the desired effect. Furthermore, existing scrapers, such as... Figure 3 As shown, the scraping contact surface is a symmetrical arc surface, and there is still a large gap between it and the inner wall of the barrel when scraping.

[0020] The structure of the stirring device provided by this utility model is as follows: Figure 4 , Figure 5 and Figure 7 As shown, the container includes a horizontal mixing tank body 1 with a main shaft 9 inserted inside. Several mixing rod seats 4 are connected to the circumference of the main shaft. Each mixing rod seat is connected to a scraper 6 via a support rod 5. The mixing rod seats and the support rods are connected via a rotating joint, which is equipped with a locking device. The scraper 6 is as follows: Figure 6 As shown, the scraper contact surface has an asymmetrical arc surface structure. The locking device consists of a locking screw 7 and a nut 8.

[0021] In a further improvement, the included angle θ between the side of the scraper and the axis of the stirring rod seat is 30° to 50°.

[0022] The design and manufacturing process of this utility model is as follows:

[0023] Based on the specific structure, shape, and size of the horizontal mixing pot, a new type of shovel-shaped mixing rod was designed in detail, such as... Figure 5 As shown in the diagram, the angle "θ" should reach 30° to 50° to ensure the scooping effect of different fillings; the scraping contact surface on the scraper 6 that contacts the inner wall of the barrel is designed according to three-dimensional simulation dynamic design, theoretically achieving seamless fit; a locking structure is added with locking screws 7 and nuts 8, and the production and assembly are completed.

[0024] The working process of this utility model is as follows:

[0025] Install the new shovel-type stirring rod into the horizontal mixing pot, adjust the position of the new support rod 5 so that the scraping contact surface of the scraper 6 edge is in close contact with the inner wall of the pot, and then use the locking screw 7 and the nut 8 to lock it in place.

[0026] Start the equipment; the main shaft drives the new shovel-type stirring rod to rotate. For example... Figure 4 As shown, the tilt angle "γ" allows the filling adhering to the barrel wall to be scooped up, turned over, mixed, and stirred, achieving the desired bottom-scooping effect and effectively solving the technical problem of sticking and crusting when mixing and heating high-viscosity fillings in a horizontal mixing pot.
