Description

Technical Field

[0001] This utility model relates to the field of soybean protein particle processing technology, specifically a soybean protein particle cooling and conveying device. Background Technology

[0002] Soy protein granules are a high-value-added food ingredient made from soy protein isolate through extrusion puffing and granulation processes. They are widely used in vegetarian meat products, nutrition bars, and pet food. During the production process, the granules typically reach temperatures of 80-100℃ after granulation and must be rapidly cooled to below 40℃ to prevent protein denaturation, clumping, or microbial growth.

[0003] A Chinese patent discloses a soybean protein particle cooling and screening device (authorization announcement number CN215390686U). The patented technology includes:

[0004] The screening screen inside the screening cylinder can be used to screen soybean protein particles, thereby improving the quality of soybean protein particle products. This screening equipment is easy to use, has high screening efficiency, and is highly practical.

[0005] By using air nozzles and blowers installed inside the screening cylinder, air can be supplied to the inside of the screening cylinder. This air supply can disperse and dry the soybean protein particles being screened, thereby improving screening efficiency.

[0006] However, it has certain drawbacks: during the screening process, the soybean protein particles fall freely inside the screening cylinder, and the contact time with the cold airflow is short, resulting in insufficient heat exchange and limited cooling efficiency; in addition, the cold airflow only acts on the screening stage, and after the particles are discharged through the outlet, there is no continuous means of heat dissipation. The accumulated particles are prone to local overheating due to the difficulty in dissipating internal heat, which affects the stability of product quality. Utility Model Content

[0007] The purpose of this invention is to provide a soybean protein particle cooling and conveying device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A soybean protein pellet cooling and conveying device includes a cooling tank body and a tank cover fixed to the upper end of the cooling tank body. A C-shaped plate is fixedly sleeved on the outside of the cooling tank body, and a sieve plate is fixedly sleeved inside the cooling tank body. A motor is fixedly sleeved on the upper surface of the tank cover, and a stirring rod is fixedly sleeved on the output end of the motor. Multiple stirring blades are fixedly sleeved on the outside of the stirring rod from top to bottom. A blower mechanism is provided on the left side surface and inside of the cooling tank body.

[0010] A conveyor belt is fixedly connected to the lower end of the C-shaped plate. Baffles are installed on both the front and rear sides of the inner side of the conveyor belt. L-shaped blocks are fixedly connected to the surfaces of the two baffles on opposite sides. A leveling mechanism is provided at the front and rear edges of the upper surface of the conveyor belt.

[0011] As a further embodiment of this utility model: the blower mechanism includes a blower and multiple air rings distributed from top to bottom. The inlet and outlet ends of the blower are respectively fixedly connected to a filter plate and an air hood. The right side surface of the air hood is fixedly connected to an air duct I communicating with its interior. Multiple air holes are opened on the inner surface of the air rings. An air duct II communicating with its interior is fixedly connected between each two adjacent air rings.

[0012] As a further embodiment of this utility model: the leveling mechanism includes a C-shaped plate II, and a plurality of leveling rods are rotatably connected through the upper surface of the C-shaped plate II from front to back. A gear is fixedly sleeved on the upper outer end of the leveling rod, and a leveling plate is fixedly sleeved on the lower outer end of the leveling rod. A fixing block is fixedly connected to the front end of the upper surface of the C-shaped plate II, and a telescopic cylinder is fixedly connected to the front surface of the fixing block. A rack is fixedly connected to the telescopic end of the telescopic cylinder.

[0013] As a further embodiment of this utility model: the stirring rod is located inside the cooling tank body, the stirring blade is located above the sieve plate, the lower end of the C-shaped plate is fixed to the front and rear edges of the upper surface of the conveyor belt, and the lower end of the L-shaped block is fixed to the edge of the upper surface of the conveyor belt.

[0014] As a further embodiment of this utility model: the air ring is fixed to the inner surface of the cooling tank body, the air shroud is fixed to the left side surface of the cooling tank body, the first air duct movably penetrates the left side surface of the cooling tank body, and one end of the first air duct is fixed to the uppermost air ring, the first air duct is connected to the inside of the air ring, and the air ring is connected to the inside of the second air duct.

The baffle is located inside the second C-shaped plate, and the rack is meshed with the gear.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes the coordinated operation of a conveyor belt and a leveling mechanism. The conveyor belt receives and continuously transports qualified particles after screening, while side baffles limit lateral spillage of particles, ensuring stable material transport. In the leveling mechanism, a telescopic cylinder drives a rack and pinion to reciprocate, causing the gears and leveling rod to swing synchronously. This allows the leveling plate to dynamically spread the accumulated particles on the conveyor belt surface at a controllable frequency, breaking up particle clusters, increasing the heat dissipation contact area, and significantly improving cooling uniformity and efficiency. At the same time, it avoids manual intervention, achieving automated continuous leveling operations. This solves the problems of localized overheating and uneven cooling caused by particle accumulation in traditional conveying processes, further enhancing the overall cooling efficiency of the system.

[0024] A valve connected to the interior of the cooling tank 1 is fixed to the lower surface of the tank body 1. When opened, the valve is used to discharge soybean protein particles.

[0025] The cooling tank body 1 and the tank cover 2 are fixed together by bolts;

[0026] The upper surface of the can lid 2 is fixed to the left side of the motor 5 with a feed pipe, which is used to pour soybean protein particles into the cooling tank body 1 and also to discharge gas.

[0027] The sieve plate 4 is used to screen soybean protein particles, separating larger soybean protein particles so that soybean protein particles that meet the specifications fall down.

[0028] The stirring blade 7 is used to stir the material so that it can pass through the sieve plate 4 quickly. The bottom stirring blade 7 is very close to the sieve plate 4, but does not contact it.

[0029] The blower 9 is used to draw air from the outside, so that air is sprayed out through the air hole 14 to cool the material.

[0030] Filter plate 11 is used to filter dust and impurities in the air;

[0031] The air ring 10 is located outside the stirring blade 7, and there will be no interference between the two.

[0032] exist Figure 1 and Figure 4In the middle section: A conveyor belt 16 is fixedly connected to the lower end of C-shaped plate 3. The lower end of C-shaped plate 3 is fixed to the front and rear edges of the upper surface of conveyor belt 16. Above conveyor belt 16, baffles 17 are installed on both the front and rear sides of the inner side of C-shaped plate 3. L-shaped blocks 18 are fixedly connected to the surfaces of the opposite sides of the two baffles 17. The lower ends of the L-shaped blocks 18 are fixed to the edges of the upper surface of conveyor belt 16. A leveling mechanism 19 is provided on both the front and rear edges of the upper surface of conveyor belt 16. The leveling mechanism 19 includes a second C-shaped plate 20. The lower end of the second C-shaped plate 20 is fixed to the conveyor belt 16. The upper surface of the C-shaped plate 20 is located on the right side of the C-shaped plate 3. The baffle 17 is located inside the C-shaped plate 20. Multiple paving rods 21 are rotatably connected through the upper surface of the C-shaped plate 20 from front to back. Gears 22 are fixedly sleeved on the upper outer end of the paving rods 21, and paving plates 23 are fixedly sleeved on the lower outer end of the paving rods 21. A fixing block 24 is fixedly connected to the front end of the upper surface of the C-shaped plate 20. A telescopic cylinder 25 is fixedly connected to the front surface of the fixing block 24. A rack 26 is fixedly connected to the telescopic end of the telescopic cylinder 25. The rack 26 is meshed with the gear 22.

[0033] The cooled and screened soybean protein particles fall onto the surface of conveyor belt 16 and are conveyed from left to right. During the conveying process, the soybean protein particles are exposed and cooled again.

[0034] Two baffles 17 are located on the front and rear sides of the conveyor belt 16, respectively. Their lower surfaces are very close to the conveyor surface but do not contact it. They are used to shield the soybean protein particles and prevent them from falling into the gap between the frame of the conveyor belt 16 and the conveyor surface.

[0035] The paving rod 21 and the C-shaped plate 20 can be rotatably connected by bearings;

[0036] The flat plate 23 is located between the two baffles 17, and the lower surface of the flat plate 23 is very close to the conveying surface of the conveyor belt 16, but does not contact it;

[0037] The telescopic cylinder 25 is preferably an electric cylinder with an adjustable telescopic speed; it is used to drive the rack 26 to move back and forth, thereby driving the gear 22 to continuously rotate forward and backward, which in turn drives the spreading plate 23 to swing to spread the soybean protein particles, thus avoiding the soybean protein particles from being piled up during transportation and making it difficult to cool them effectively.

[0038] Spread the flat plate 23 and swing it at an appropriate speed to avoid throwing out the soybean protein particles.

[0039] The working principle of this utility model is as follows: After the material is put into the cooling tank body 1 through the feed pipe of the tank cover 2, the motor 5 drives the stirring rod 6 to rotate the multi-layer stirring blades 7 to stir the soybean protein particles. The soybean protein particles are dynamically screened through the sieve plate 4. Qualified particles fall through the sieve holes to the conveyor belt 16, while larger particles remain above the sieve plate 4. At the same time, the fan 9 draws in air through the filter plate 11 and supplies air to the multi-layer air ring 10 through the air cover 12 and the air duct 13. The airflow is sprayed out from the air hole 14 to cool the soybean protein particles. The cooled and screened particles are discharged through the valve to the conveyor belt 16. During the conveying process, the baffle 17 restricts the overflow of particles. At the same time, the telescopic cylinder 25 drives the rack 26 to reciprocate. Through the gear 22, the leveling rod 21 drives the leveling plate 23 to swing, so that the accumulated particles are evenly spread on the surface of the conveyor belt 16 to enhance the heat dissipation effect.
