Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, and in particular to a spiral dough mixer for preventing sticking to a pot. Background Technology

[0002] The spiral dough mixer features a unique spiral mixing design that simulates the hand kneading process through low-speed, high-torque operation, ensuring that the dough is evenly mixed without sticking. Its inner surface is treated with a special non-stick coating, and together with precise temperature control components, it effectively prevents the dough from sticking together. The gap between the spiral rod and the cylinder is precisely calculated to ensure mixing efficiency while reducing residue. An automatic scraping device cleans the inner wall in real time, further eliminating sticking problems. This equipment supports multiple speed settings to adapt to the needs of doughs with different hardness, greatly improving the efficiency and quality of pasta production. It is suitable for making steamed buns and dumplings, and greatly reduces the time spent on manual dough kneading.

[0003] The spiral dough mixer mainly consists of a spiral stirring rod, a stainless steel inner pot, a drive motor, a base, and control components. The spiral stirring rod adopts a conical design, with its bottom fitting snugly against the inner pot to ensure no dead corners in the mixing. The inner pot surface is coated with an anti-stick layer to prevent the dough from sticking together. The motor drives the spiral rod to rotate at a low speed through a reduction mechanism to maintain stable kneading. The base provides stable support and is equipped with adjustable feet to adapt to different work surfaces. The control components integrate speed adjustment and timing functions, making it easy to operate. The overall structure is compact and easy to disassemble and clean.

[0004] In spiral dough mixers, the connection between the spiral rod and the drive shaft is often secured with pins or locking nuts. Over time, this can lead to difficulties in disassembly due to flour clumping or grease hardening, requiring tools to be used and risking damage to the threads. Furthermore, the precise gap between the bottom of the spiral rod and the inner pot means that misalignment during reassembly can affect mixing performance or scratch the anti-stick coating. Additionally, some models require removing the top protective cover before removing the spiral rod, a cumbersome process that increases cleaning dead zones and reduces efficiency. Dough residue can also remain on the inner wall of the drum, affecting the quality of the next batch of dough. Therefore, a spiral dough mixer with an anti-stick design is proposed to address these issues. Utility Model Content

[0031] 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 protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a spiral dough mixer with an anti-stick pan, comprising a support column 3, which is a vertical column providing basic support for the entire dough mixer. A control panel 20 is fixedly connected to the top of the support column 3. The control panel 20 is rectangular and has operation buttons and a display screen on its surface for controlling the operation of the dough mixer. A motor 4 is installed at the bottom of the control panel 20, serving as the core power source of the dough mixer. Its drive end is vertically downward and fixedly connected to a rotating column 14. The rotating column 14 is a cylindrical structure with axially oriented holes inside, allowing the bottom end of a latch 8 to slide up and down within these holes. Two limiting semi-rings 12 are symmetrically fixedly connected to the inner side of the rotating column 14. It is semi-circular in shape, with a track formed on its inner side for the hollow locking column 7 to slide. The hollow locking column 7 is a hollow cylinder, and its bottom end is fixedly connected to the spiral rod body 6. The spiral rod body 6 is spirally ascending and is used to stir flour and water. The inside of the rotating column 14 is also slidably connected to the column head 13. The column head 13 is a columnar structure, and its bottom end is fixedly connected to the fixing rod 10. The fixing rod 10 extends laterally, and a retaining ring 11 is sleeved on the outside. The retaining ring 11 can slide left and right on the fixing rod 10, and its outside is slidably engaged with the hollow locking column 7. The bottom end of the fixing rod 10 is fixedly connected to the buckle ring 9. The buckle ring 9 is annular and the buckle rod 8 can pass through and slide inside. The bottom end of the support column 3 is fixedly connected to the scraping component for cleaning the inside of the machine body 1.

[0033] Reference Figure 2 , Figure 4 The scraping assembly includes a base 2, which is flat and horizontally placed. Its top end is fixedly connected to the bottom end of a support column 3, connecting the support column 3 to the machine body 1. The top end of the base 2 is fixedly connected to the machine body 1, which is cylindrical and serves as the main space for kneading dough. A second motor 18 is installed inside the machine body 1. A second gear 17 is fixedly connected to the drive end of the second motor 18. The second gear 17 is located at the center inside the machine body 1. The outer side of the second gear 17 meshes with two first gears 16, which are symmetrically distributed on both sides of the second gear 17. The outer sides of each first gear 16 mesh with a gear ring 15. 5 is a circular ring structure, fitted inside the machine body 1. Two scrapers 5 are fixedly connected to the top of the toothed ring 15. The scrapers 5 are long and arc-shaped, and their outer sides are tightly fitted to the inner side of the machine body 1 and can slide. The inner side of the machine body 1 is provided with a ring track, which cooperates with the outer side of the toothed ring 15 to realize the rotation of the toothed ring 15. The top of the gear 16 is fixedly connected to a partition 21. The partition 21 is disc-shaped, and its bottom end is rotatably connected to the toothed ring 15, which plays a supporting and limiting role. The outer side of the spiral rod 6 is fixedly connected to a stirring plate 19. The stirring plate 19 is arc-shaped and its outer side maintains a certain gap with the inner side of the machine body 1 and can slide, which is used to stir the raw materials.

[0034] Working Principle: When users need to make steamed buns, dumplings, or other pasta dishes, they first need to mix flour with an appropriate amount of water to knead the dough to obtain a suitable consistency for subsequent processing. After the user puts the flour, water, and other ingredients into the machine body 1, they start the motor 4 by pressing the button on the control panel 20. The motor 4 drives the rotating column 14 to rotate, which in turn drives the connected spiral rod 6 and mixing blade 19 to rotate together, mixing and kneading the ingredients. Since different pasta dishes require different viscosity, the kneading machine is designed with a replaceable spiral rod 6 to meet this requirement. When the user needs to replace the spiral rod 6, they should first turn off the machine and allow the rotating column 14 to rotate. Stop rotating, then pull the lever 8 upwards and slide it away from the buckle 9, releasing the fixation on the spiral rod 6. Then, pull the buckle 9 open, and the buckle 9 will move the fixing rod 10 backwards. The retaining ring 11 on the outside of the fixing rod 10 will also slide backwards. Under the restriction of the limiting half ring 12, the retaining ring 11 will always remain inside the limiting half ring 12. When the retaining ring 11 slides to the middle position and no longer contacts the hollow retaining post 7, the spiral rod 6 can be easily pulled out. Insert the new spiral rod 6, align the hollow retaining post 7 with the limiting half ring 12 and the retaining ring 11, and then follow the reverse steps of disassembly to insert the lever 8 into the buckle 9 and press it down to fix it, completing the replacement of the spiral rod 6.

[0035] During the operation of the dough mixer, the raw materials will splash everywhere during mixing, and the sticky dough will easily adhere to the inner wall of the machine body 1. To solve this problem, the user can start the scraping component when the machine is running and turn on the motor 18. The motor 18 drives the gear 17 to rotate. The rotation of the gear 17 drives the gear 16 at both ends of the outer side to rotate synchronously through the meshing relationship. When the gear 16 rotates, it drives the gear ring 15 to rotate rapidly through meshing with the gear ring 15. When the gear ring 15 rotates, it drives the two scrapers 5 fixed at its top to slide along the inner wall of the machine body 1. The scrapers 5 scrape the dough adhering to the inner wall of the machine body 1, so that the dough returns to the center of the machine body 1 and is mixed with the main dough, and participates in the mixing again. Through the continuous work of the scraping component, the dough is effectively prevented from sticking to the pot, ensuring uniform dough mixing and improving dough mixing efficiency and quality.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
