Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a double-helix cross-stirring frying pan device. Background Technology

[0002] As a core piece of equipment in the food processing industry, the stirring wok plays a crucial role in the production of hot pot base. Through continuous mechanical stirring combined with precise heat transfer, the stirring wok causes the diverse components of the hot pot base, such as oils, spices, and seasonings, to be stir-fried at high temperatures, resulting in the unique aroma, color, and flavor of the hot pot base.

[0003] In the prior art, Chinese utility model patent with publication number CN219002799U discloses a wok stirring mechanism, including a wok and a rotating shaft, with stirring blades and scrapers mounted on the rotating shaft, and the rotating shaft is mounted inside the wok via a crossbeam. This prior art has the following technical problems:

[0004] 1. The stirring blade has a single running trajectory, which cannot make the various components of the hot pot base roll fully in the pot, resulting in uneven mixing, low mixing efficiency, and incomplete integration of the components, thus affecting the overall taste and quality of the product.

[0005] 2. When stir-frying high-viscosity materials (such as hot pot base containing 60% oil), the load on the stirring shaft increases, and the stirring shaft is prone to vibration, deflection and other phenomena, which affect the normal operation of the stirring shaft, reduce the uniformity and efficiency of material mixing, and reduce the taste and quality of the product; the friction between the scraper on the stirring shaft and the wok increases, shortening the service life of the equipment. Utility Model Content

[0006] This invention provides a double-helix cross-stirring frying pan device, which can solve the problems of uneven material mixing, low mixing efficiency, and the impact on the taste and quality of products.

[0007] This application provides the following technical solution:

[0008] A double-helix cross-stirring wok device includes a wok body and a stirring mechanism. The wok body is mounted on a frame, and the stirring mechanism is located above the wok body. The stirring mechanism includes a first stirring shaft, a second stirring shaft, and a drive assembly. The upper ends of the first and second stirring shafts are respectively connected to the drive assembly, and the lower ends of the first and second stirring shafts extend to the inside of the wok body. The second stirring shaft is sleeved on the outside of the first stirring shaft. The first and second stirring shafts rotate in opposite directions, and a gyroscope is mounted on the first stirring shaft.

[0009] Beneficial effects: During operation, the first and second stirring shafts rotate in opposite directions, creating a complex mixing flow field within the wok body. Compared to single-shaft stirring, this effectively reduces dead zones, prevents material agglomeration, and ensures uniform mixing of all components, guaranteeing the final product's taste and flavor, improving product quality, and increasing mixing efficiency, thus boosting production efficiency. A gyroscope is installed on the first stirring shaft to monitor its tilt angle and rotation speed in real time. The shaft speed can be adjusted based on the monitoring results, effectively preventing shaft vibration, ensuring the stability and uniformity of material mixing, guaranteeing normal shaft operation, and preventing severe friction between the stirring blades or scrapers and the wok body, thus extending the equipment's lifespan.

[0010] Furthermore, the gyroscope is located at the lower end of the first stirring shaft.

[0011] Beneficial effects: The end of the first stirring shaft is the position with the greatest material resistance and the most significant vibration. By setting the gyroscope at the end of the first stirring shaft, the collected data can more accurately reflect the true load state.

[0012] Furthermore, the lower end of the first stirring shaft is connected to the wok body via a bearing.

[0013] Beneficial effects: By fixing the end of the first stirring shaft to the main body in a rotatable manner through a bearing, it is possible to effectively prevent the stirring shaft from tilting, ensuring normal operation of the equipment and extending its service life.

[0014] Furthermore, the first stirring shaft is provided with a first stirring blade, and the second stirring shaft is provided with a second stirring blade. Both the first stirring blade and / or the second stirring blade are provided with multiple protrusions arranged in an alternating pattern.

[0015] Beneficial effects: The raised texture on the stirring blades forms a turbulent boundary layer during rotation, achieving optimal mixing efficiency.

[0016] Furthermore, a scraper is provided on the first stirring shaft.

[0017] Beneficial effects: The edge of the scraper matches the curvature of the bottom of the wok. When the first stirring shaft rotates, the scraper moves with the shaft and continuously scrapes the inner wall (including the wok wall and bottom), scooping up the adhering material in time and preventing the food from burning due to high temperature.

[0018] Furthermore, the drive assembly includes a first bevel gear fixedly connected to the first stirring shaft, a second bevel gear fixedly connected to the second stirring shaft, and a third bevel gear meshing with the first and second bevel gears. The first and second bevel gears are symmetrically arranged at both ends of the third bevel gear, and the third bevel gear is fixedly connected to the drive shaft of the drive motor.

[0019] Beneficial effects: The third bevel gear acts as the driving gear, simultaneously meshing with the symmetrical first and second bevel gears, directly achieving reverse rotation of the two stirring shafts, resulting in high transmission efficiency, strong rotational synchronization, balanced force, and reduced vibration.

Detailed Implementation

[0024] The following detailed description illustrates the specific implementation method:

[0025] Example 1

[0026] like Figure 1 , Figure 2 As shown, a double-helix cross-stirring wok device includes a wok body 1 and a stirring mechanism 2. The wok body 1 has rotating shafts on both sides and is rotatably mounted on a frame 3 via the rotating shafts. The stirring mechanism 2 is located above the wok body 1 and is mounted on the frame 3 via a bracket 4. A controller is located on the frame 3.

[0027] The stirring mechanism 2 includes a first stirring shaft 5, a second stirring shaft 6, and a drive assembly. The upper ends of the first stirring shaft 5 and the second stirring shaft 6 are connected to the drive assembly, and the lower ends of the first stirring shaft 5 and the second stirring shaft 6 extend to the inside of the wok body 1. The second stirring shaft 6 is sleeved on the outside of the first stirring shaft 5. Multiple sealed bearings are provided between the first stirring shaft 5 and the second stirring shaft 6. The first stirring shaft 5 and the second stirring shaft 6 rotate in opposite directions. The lower end of the first stirring shaft 5 extending downward through the second stirring shaft 6 is provided with a first stirring blade 7, and the lower end of the second stirring shaft 6 is provided with a second stirring blade 8, which is located above the first stirring blade 7. The first stirring blade 7 and the second stirring blade 8 can also adopt common types such as paddle type, blade type, spiral type, frame type, and anchor type. In this embodiment, the first stirring blade 7 and the second stirring blade 8 are both spiral stirring blades.

[0028] A gyroscope 9 is mounted on the first stirring shaft 5. Specifically, a mounting hole is provided at the lower end of the first stirring shaft 5, and the gyroscope 9 is installed in the mounting hole at the lower end of the first stirring shaft 5. A sealing plug is provided at the opening of the mounting hole to seal the mounting hole. Heat insulation devices such as heat insulation cotton are installed inside the mounting hole. The gyroscope 9 can be a MEMS gyroscope, and a remote transmission module is built into the gyroscope 9. The gyroscope 9 is wirelessly connected to the controller through the remote transmission module. The remote transmission module can be a Bluetooth module.

[0029] The drive assembly includes a first bevel gear 10 fixedly connected to the first stirring shaft 5, a second bevel gear 11 fixedly connected to the second stirring shaft 6, and a third bevel gear 12 meshing with the first bevel gear 10 and the second bevel gear 11. The first bevel gear 10 and the second bevel gear 11 are symmetrically arranged at both ends of the third bevel gear 12. The third bevel gear 12 is fixedly connected to the drive shaft of the drive motor 13, and the drive motor 13 is electrically connected to the controller.

[0030] The processing method is as follows: When frying materials, the drive motor 13 drives the first bevel gear 10 and the second bevel gear 11 to rotate through the third bevel gear 12. The first bevel gear 10 and the second bevel gear 11 rotate in opposite directions, thereby realizing the opposite rotation of the first stirring shaft 5 and the second stirring shaft 6. If the second stirring blade 8 located above rotates clockwise under the drive of the second stirring shaft 6, causing the material to generate a centrifugal vortex, then the first stirring blade 7 located below rotates counterclockwise under the drive of the first stirring shaft 5, causing the material to centrifugally diffuse outward, effectively preventing the material from clumping and ensuring that the components of the material are mixed evenly. The controller uses the gyroscope 9 to detect the tilt angle and speed of the stirring shaft in real time, and adjusts the speed of the stirring shaft according to the detection results, effectively preventing the stirring shaft from vibrating, ensuring the stability and uniformity of the material stirring, ensuring the normal operation of the stirring shaft, and ensuring the service life of the equipment.

[0031] Example 2

[0032] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that both the first stirring blade 7 and the second stirring blade 8 are provided with multiple staggered protrusions 14, which are trapezoidal in structure. The first stirring blade 7 and the second stirring blade 8 are made of food-grade stainless steel and have been sandblasted. The blade radii of the first stirring blade 7 and the second stirring blade 8 decrease from top to bottom.

[0033] Example 3

[0034] like Figure 3As shown, the difference between this embodiment and Embodiment 1 is that the stirring mechanism 2 is mounted on the wok body 1 via a bracket 4. The lower end of the first stirring shaft 5 is rotatably connected to the wok body 1 via a bearing. The bottom of the groove in the wok body 1 is provided with a bearing mounting hole, which cooperates with the bearing to limit the first stirring shaft 5 and prevent it from tilting. A gyroscope 9 can be located in the middle of the first stirring shaft 5 to detect the tilt angle and rotation speed of the middle of the first stirring shaft 5 in real time, and to detect whether the first stirring shaft 5 vibrates or tilts.

[0035] Example 4

[0036] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that a scraper 15 is provided on the first stirring shaft 5. The scraper 15 has an arc-shaped structure, which matches the curvature of the inner wall of the wok body 1. The scraper 15 contacts the inner wall of the wok body 1, making it easy to scrape off the material adhering to the inner wall of the wok body 1.
