Description

Technical Field

[0001] This utility model relates to the field of pet food production, specifically a feed mixing device for pet food production. Background Technology

[0002] In the production of pet food, in order to make the pet food nutritionally balanced and palatable, it is necessary to thoroughly mix a variety of different raw materials.

[0003] Currently, some pet food production feed mixing devices on the market have several shortcomings. On the one hand, some devices rely solely on simple overall rolling for raw material mixing, making it difficult to ensure uniform mixing of various ingredients. This is especially true for raw materials with significant differences in particle size and density, which can easily lead to mixing dead zones, poor mixing effects, and inconsistent final product quality, affecting pets' health and appetite. On the other hand, when mixing raw materials containing special components such as moisture and oil, existing devices are prone to material sticking to the walls. This not only wastes raw materials and increases production costs, but the residual material may also deteriorate within the device, contaminating subsequent feed production and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a feed mixing device for pet food production. By setting up multiple layers of stirring blades with different shapes and angles, the feed raw materials are stirred from multiple dimensions, eliminating blind spots in the stirring process, improving the uniformity and efficiency of mixing, and meeting the needs of pet food production.

[0030] 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.

[0031] refer to Figure 1-3A feed mixing device for pet food production includes a base 1, a tank 2, a drive assembly 3, a stirring rod 4, a multi-layer stirring blade assembly 5, a discharge port 6, and a discharge valve 7. The base 1 is the supporting structure of the entire device, providing a stable operating platform. The base 1 can be made of metal or sturdy engineering plastic, with a certain weight and strength to ensure the stability of the device during operation. The base 1 can be an L-shaped block to meet different height design requirements. The tank 2 can be a cylindrical tank with an open top, made of food-grade stainless steel, which is corrosion-resistant and easy to clean. The tank 2 is located on top of the base 1 and is the place for mixing and crushing feed raw materials. The top of the tank 2 has an open feed inlet for adding different raw materials and for easy observation of the mixing process. The inner wall of the tank 2 can be polished to a roughness of ≤0.8μm to reduce material sticking to the wall. A discharge port 6 is located on the side of the tank body 2 away from the drive assembly 3. The discharge port 6 can be located at the bottom of the tank body 2, 10-15cm from the bottom wall, and is designed at a 45° angle to facilitate the gravity flow of materials. The outlet diameter can be 10-15cm to facilitate the packaging of mixed feed. The discharge port 6 is equipped with a discharge valve 7, which can control the opening and closing of the discharge port 6 to achieve discharge control. The discharge valve 7 can be a manual ball valve with a diameter matching the discharge port 6. The valve stem end is equipped with an extended handle for easy operation. This is existing technology and will not be described in detail here. The drive assembly 3 is located on the top surface of one side of the base 1 and can be fixed by bolts. It can provide power for the rotation of the stirring rod 4. 4 is rotatably and sealed inside the tank 2. The stirring rod 4 can be a solid stainless steel rod. The top can be rotatably connected to the top wall of the tank 2 through a bearing seat. The bottom passes through the base 1 and is connected to the drive assembly 3. A mechanical seal is provided at the penetration point to the bottom of the tank 2 to prevent material leakage. This is existing technology and will not be described in detail here. The multi-layer stirring blade assembly 5 is set on the stirring rod 4. The stirring rod 4 rotates under the drive of the drive assembly 3, thereby driving the multi-layer stirring blade assembly 5 to stir the material in the tank in multiple directions. This stirs the feed raw materials from multiple dimensions, eliminates stirring blind spots, improves the mixing uniformity and mixing efficiency of the feed, and meets the needs of pet food production.

[0032] In some embodiments, the drive assembly 3 includes a drive motor 31, a drive wheel (not shown), a driven wheel (not shown), and a belt 32. The drive motor 31 is located on the top surface of one side of the base 1 and can be fixed with bolts to provide power for stirring the feed. The drive motor 31 can be a variable frequency motor with a power of 1.5-3kW and an adjustable speed of 0-1500r / min. Its surface can be provided with a heat dissipation grille to convert electrical energy into mechanical energy. The drive wheel is coaxially mounted on the output shaft of the drive motor 31 and can be connected by a key, allowing it to rotate synchronously with the drive motor 31. The driven wheel is coaxially mounted on the bottom of the stirring rod 4 and can be connected by a key, and is connected to the drive wheel via the belt 32. During operation, the drive motor 31 drives the drive wheel to rotate, and the power is transmitted to the driven wheel through the belt 32, thereby driving the stirring rod 4 to rotate, realizing the operation of the multi-layer stirring blade assembly 5. The belt drive can buffer load impacts and facilitates the adjustment of the speed of the stirring rod 4 (by replacing the drive and driven wheels with different diameters).

[0033] In some embodiments, the multi-layer stirring blade assembly 5 includes a first stirring blade 51, a second stirring blade 52, and a third stirring blade 53. The first stirring blade 51 is located at the bottom of the tank 2 and can stir the material at the bottom of the tank 2. The second stirring blade 52 is located in the middle of the tank 2 and can drive the circulation of the middle layer of material. The third stirring blade 53 is located at the top of the tank 2 and can realize the diffusion of the upper layer of material. The three layers of blades are distributed along the axial direction of the stirring rod 4, covering the entire height of the tank 2 and eliminating the stirring blind zone.

[0034] In some embodiments, the first stirring blade 51 can be a turbine-type stirring blade with a diameter of 40 cm. Its blades are radially inclined and generate an upward vortex when rotating at high speed, which can lift the heavy materials (such as mineral particles) deposited at the bottom of the tank and form a longitudinal cross-mixing with the light materials on the upper layer, such as puffed grains. The second stirring blade 52 can be a ribbon-type stirring blade with a diameter of 55 cm and a pitch of 60 cm. The spiral blades are close to the tank wall and can push the material adhering to the tank wall towards the center when rotating, avoiding sticking to the wall and forming a lateral cross-collision with the material in the central area. The third stirring blade 53 can be a paddle-type stirring blade with 4-6 blades. The paddle diameter is 50 cm and the angle between the paddle and the axis can be 45°. The blades stir in a horizontal direction and can quickly spread the newly added light materials (such as grain powder) to the surrounding area and spread them throughout the tank. The three types of blades work together to form a three-dimensional mixing flow field.

[0035] In some embodiments, the height between the first stirring blade 51 and the inner bottom wall of the tank 2 is 5-8cm. This distance ensures that the turbine blades fully contact the material at the bottom of the tank, avoids wear caused by friction between the blades and the inner bottom wall of the tank 2, and provides space for material flow to enhance the vortex effect.

[0036] In some embodiments, the height between the third stirring blade 53 and the bottom wall of the tank 2 is two-thirds to four-fifths of the height of the tank 2. This position can cover the upper half of the material in the tank. When the material is added, the paddle blades can quickly spread it from the top to the middle, and mix it quickly with the material circulating in the middle layer, shortening the initial mixing time.

[0037] In some embodiments, a cover plate (not shown in the figure) is also included. The cover plate is detachably provided at the top opening of the tank 2 and can be detachably connected by bolts to facilitate feeding and cleaning of the tank 2. The cover plate can prevent material from splashing during stirring. The cover plate is made of transparent acrylic sheet material, and its transparency makes it easy to observe the internal mixing state. The edge of the cover plate can be provided with a silicone sealing ring, which not only facilitates the observation of the mixing state but also prevents dust from overflowing.

[0038] In some embodiments, a controller 8 is also included, which is disposed on the base 1 and electrically connected to the drive assembly 3. The controller 8 may integrate a start / stop button, a speed adjustment knob, and a timing function, and can set the stirring time (0-60 minutes) and speed (300-500 r / min) according to the material characteristics to achieve automated control and improve mixing efficiency and consistency.

[0039] The specific working principle is as follows:

[0040] Open the lid and, according to the desired pet food formula, add the pet food raw material solid pellets, powder, and liquid additives in proportion through the top opening of the can 2. Close the lid and press the start button on the controller 8 to start the drive motor 31. The output shaft of the drive motor 31 drives the drive wheel to rotate, which in turn drives the driven wheel to rotate via the belt 32. The driven wheel then drives the stirring rod 4 to rotate. The rotation of the stirring rod 4 drives the multi-layer stirring blade assembly 5 to rotate. The third stirring blade 53 rotates, quickly spreading the newly added raw material throughout the can; the second stirring blade 52 rotates, causing the material to tumble up and down, "scooping up" the material on the can wall and throwing it towards the center, creating a lateral cross-collision with the material in the central area; the first stirring blade 51 rotates, generating a vortex that lifts the heavy material deposited at the bottom of the can upwards, creating a longitudinal cross-mixing with the upper light material and shearing the clumps. Combined with the kneading effect of the second stirring blade 52, this ensures that liquid additives such as oils are evenly dispersed into the solid material. After mixing is complete, drive motor 31 stops, discharge valve 7 is opened, and the mixed feed is discharged through discharge port 6. It can be transported to the end collection device through discharge pipe to complete the discharge process.
