[0002] Food premixes, as an important component of the food processing industry, are playing an increasingly prominent role and have increasingly prominent applications. They are materials made by pre-mixing various food ingredients in a certain proportion, designed to simplify food processing and improve production efficiency.

[0003] In food production and processing, by premixing various raw materials, food manufacturers can save time on weighing and mixing ingredients on-site, thereby accelerating production. Furthermore, because premixes are precisely proportioned, they ensure consistent taste and quality in every batch, enhancing the consumer experience. Additionally, centralized procurement and large-scale production of premixes can reduce unit costs and improve overall profitability. Therefore, food premixes play an indispensable role in modern food processing. They not only improve production efficiency and guarantee product quality but also effectively reduce costs for both manufacturers and consumers. With continuous technological advancements, the application areas of premixes will become even wider, bringing consumers more delicious and healthy choices.

[0004] Existing food ingredient mixing equipment comes in various forms, but most employ a single-inlet feeding method. For example, Chinese utility model patent CN209679987U discloses a rapid ingredient mixing device. The aforementioned prior art uses a mixing hopper located on one side of the mixing drum for feeding. Each material tends to accumulate at one end of the mixing drum upon addition, making mixing difficult and resulting in low material mixing efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a food raw material premixing and stirring device that can effectively improve mixing efficiency.

[0006] The food raw material premixing and stirring device of this utility model includes a base and a drum. Multiple rollers are connected to the base via roller frames. Guide ring grooves corresponding to and adapted to the rollers are connected to the outer wall of the drum. A discharge port and a feed port are respectively provided at the left and right ends of the drum. Stirring teeth are fixedly connected to the inner wall of the drum. A discharge spiral is provided on the inner wall of the drum corresponding to the discharge port. A drum drive assembly is connected between the base and the drum. Support frames are fixedly connected to both ends of the base. A sleeve passing through the feed port and the discharge port is fixedly connected between the two support frames. A conveying auger is rotatably connected inside the sleeve. The conveying auger is connected to the auger drive assembly. A feed hopper is connected to the top of the sleeve. A first discharge port, a second discharge port, and a third discharge port are provided from left to right at the bottom of the sleeve. The first discharge port is directly opposite the bottom of the sleeve. The second and third discharge ports are both at an angle to the vertical plane.

[0007] Furthermore, the feed hopper is located on the right side of the sleeve.

[0008] Furthermore, a mounting base is fixedly connected to the left side of the sleeve, and a first bearing is installed on both the mounting base and the support frame on the right side. The shaft of the conveying auger is installed between the two first bearings.

[0009] Furthermore, the roller drive assembly includes a servo motor mounted on the base and an external gear ring mounted on the outer side wall of the roller. The servo motor is connected to a drive shaft, and a gear that meshes with the external gear ring is mounted on the drive shaft.

[0010] Furthermore, the auger drive assembly includes an upper drive wheel fixedly mounted on the conveyor auger shaft and a lower drive wheel fixedly mounted on the drive shaft, with the upper drive wheel and the lower drive wheel connected by a drive belt.

[0011] Furthermore, a second bearing is installed on the support frame on the right side, and the drive shaft is installed inside the second bearing.

[0012] Working principle and process:

[0013] During operation, the servo motor drives the drive shaft to rotate, which in turn drives the drum to rotate through the engagement of gears and external gear rings, as well as the engagement of rollers and guide ring grooves. Simultaneously, the rotation of the drive shaft, through the engagement of the lower transmission wheel, transmission belt, and upper transmission wheel, drives the conveying auger, feeding food ingredients into the sleeve via the feed hopper. Under the action of the conveying auger, the material is conveyed to the left to the third discharge port. Due to the inclination of the third discharge port, only a portion of the material falls into the drum through it, while the remaining material continues to be conveyed to the left to the second discharge port. Similarly, some material passes through the second discharge port. The material falls into the drum, and the remaining material continues to be conveyed to the left to the first discharge port. Since the first discharge port is directly opposite the bottom of the sleeve, it can be ensured that the remaining material falls from the first discharge port. This allows the added food ingredients to be distributed at the left, middle and right ends of the drum. As the drum rotates, the food ingredients are continuously turned over by the action of the stirring teeth, which can mix the various ingredients in a timely manner and effectively improve the mixing efficiency of the food ingredients. After mixing, the servo motor reverses the action, which can drive the drum to reverse. Under the action of the discharge screw, the mixed material can be discharged through the discharge port.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The food raw material premixing and stirring device of this utility model can uniformly feed materials to the drum through the first discharge port, the second discharge port and the third discharge port, thereby facilitating timely mixing of food raw materials and effectively improving the mixing efficiency of food raw materials.

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] like Figure 1 , Figure 2As shown, the food raw material premixing and stirring device of this utility model includes a base 1 and a drum 14. Multiple rollers 6 are connected to the base 1 via roller frames 12. Guide ring grooves 11, corresponding to and adapted to the rollers 6, are connected to the outer wall of the drum 14. A discharge port 22 and a feed port 23 are respectively provided at the left and right ends of the drum 14. Stirring teeth 16 are fixedly connected to the inner wall of the drum 14. A discharge spiral 21 is provided on the inner wall of the drum 14 corresponding to the discharge port 22. A drum drive assembly is connected between the base 1 and the drum 14. Both ends of the sleeve are fixedly connected to support frames 5. A sleeve 13 is fixedly connected between the two support frames 5, passing through the feed inlet 23 and the discharge outlet 22. A conveying auger 17 is rotatably connected inside the sleeve 13. The conveying auger 17 is connected to a auger drive assembly. A feed hopper 15 is connected to the top of the sleeve 13. The bottom of the sleeve 13 is provided with a first discharge outlet 20, a second discharge outlet 19 and a third discharge outlet 18 from left to right. The first discharge outlet 20 is directly opposite the bottom of the sleeve 13. The second discharge outlet 19 and the third discharge outlet 18 are both at an angle to the vertical plane.

[0022] During operation, the roller drive assembly rotates the roller 14 through the cooperation of the roller 6 and the guide ring groove 11. Simultaneously, the auger drive assembly drives the conveying auger 17, feeding food ingredients into the sleeve 13 via the feed hopper 15. Under the action of the conveying auger 17, the material is conveyed to the left to the third discharge port 18. Due to the inclination of the third discharge port 18, only a portion of the material falls into the roller 14 through the third discharge port 18. The remaining material continues to be conveyed to the left to the second discharge port 19. Similarly, some material falls into the roller 14 through the second discharge port 19, and then the remaining material continues to... The material is conveyed to the first discharge port 20. Since the first discharge port 20 is directly opposite the bottom of the sleeve 13, it can be ensured that the remaining material falls from the first discharge port 20. This allows the added food ingredients to be distributed at the left, middle and right ends of the drum 14. As the drum 14 rotates, the food ingredients can be continuously turned over by the stirring teeth 16, so that the various ingredients can be mixed in time, effectively improving the mixing efficiency of the food ingredients. After mixing, the drum drive component reverses its movement, thereby driving the drum 14 to reverse. Under the action of the discharge screw 21, the mixed material can be discharged through the discharge port 22.

[0023] Example 2:

[0024] like Figure 1 , Figure 2 As shown, based on Example 1,

[0025] Furthermore, the feed hopper 15 is located on the right side of the sleeve 13, which is a reasonable position and will not interfere with the discharge from the outlet 22.

[0026] Furthermore, a mounting base 24 is fixedly connected to the left side of the sleeve 13. Both the mounting base 24 and the support frame 5 on the right side are equipped with first bearings. The shaft of the conveying auger 17 is installed between the two first bearings. This effectively ensures the operational stability of the conveying auger 17.

[0027] Furthermore, the roller drive assembly includes a servo motor 9 mounted on the base 1 and an external gear ring 10 mounted on the outer wall of the roller 14. The servo motor 9 is connected to a drive shaft 7, and a gear 8 that meshes with the external gear ring 10 is mounted on the drive shaft 7. By actuating the servo motor 9, the drive shaft 7 is driven to rotate, thereby driving the roller 14 to rotate in the cooperation of the gear 8 and the external gear ring 10.

[0028] Furthermore, an upper drive wheel 4 is fixedly mounted on the rotating shaft of the conveying auger 17, and a lower drive wheel 2 is fixedly mounted on the drive shaft 7. The upper drive wheel 4 and the lower drive wheel 2 are connected by a transmission belt 3. By rotating the drive shaft 7, the conveying auger 17 can be driven to run through the cooperation of the lower drive wheel 2, the transmission belt 3, and the upper drive wheel 4, thus eliminating the need for a separate drive mechanism for the conveying auger 17 and reducing energy consumption.

[0029] Furthermore, a second bearing is installed on the support frame 5 on the right side, and the drive shaft 7 is installed inside the second bearing. This effectively ensures the operational stability of the two drive shafts 7.
