Description

Technical Field

[0001] This utility model belongs to the field of protein powder production technology, specifically relating to a mixing device for protein powder production. Background Technology

[0002] Protein powder is a nutritional protein supplement, generally made from purified soy protein, casein, whey protein (lacking isoleucine), pea protein, or a combination of these proteins (such as a complex protein composed of soy protein, whey protein, and pea protein). Its purpose is to supplement protein for people who are deficient in it. The production and processing of protein powder requires the uniform mixing of various raw material powders, which necessitates the use of a mixing device.

[0003] However, during the production and processing in the workshop, we found that the existing powder mixing devices have the following drawbacks: Because the raw material powder is prone to absorbing moisture and agglomerating during storage, the agglomerated powder is not easily dispersed during mixing, thus affecting the uniformity of the mixture and ultimately impacting the quality of the protein powder product. Furthermore, after use, some powder tends to remain inside the container, resulting in waste.

[0004] To address these issues, we propose a novel mixing device for protein powder production. Utility Model Content

[0006] A mixing device for protein powder production includes a mixing tank. The top of the mixing tank has a feeding assembly, and the bottom of the mixing tank has multiple supporting legs. The interior of the mixing tank is divided into an upper stirring zone and a lower heating zone by a funnel-shaped bottom shell. The bottom shell has a feeding port that extends to the bottom of the mixing tank and is equipped with a valve. The feeding assembly includes an inverted frustum-shaped cylinder with an open bottom. The top of the cylinder has a feeding hopper, and a cover plate is hinged to the feeding hopper. A rotating rod is also rotatably mounted through the top axis of the cylinder.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments. Example

[0018] like Figure 1-2 As shown, this utility model provides a mixing device for protein powder production, including a mixing tank 1. The top of the mixing tank 1 is equipped with a feeding assembly 6, and the bottom of the mixing tank 1 is equipped with multiple support legs 19. The interior of the mixing tank 1 is divided into an upper stirring zone and a lower heating zone by a funnel-shaped bottom shell 2. The bottom shell 2 is equipped with a feeding port 3, which extends to the bottom of the mixing tank 1 and is equipped with a valve. The feeding assembly 6 includes an inverted frustum-shaped cylinder 6-1 with an open bottom. The top of the cylinder 6-1 is equipped with a feeding bin 6-2, and a cover plate 6-3 is hinged to the feeding bin 6-2. A rotating rod 6-4 is also rotatably mounted through the top axis of the cylinder 6-1. The bottom end of the rotating rod 6-4 is provided with a crushing roller 6-5, and the crushing roller 6-5 is provided with a spiral groove; the top axis of the mixing tank 1 is provided with a bottom-sealed rotating tube 7, the bottom end of the rotating tube 7 extends to the discharge port 3, and the rotating tube 7 located in the stirring zone is provided with a spiral stirring blade 12 and multiple stirring rods 10. The rotating tube 7 is driven to rotate by a drive motor 8 located at the top of the mixing tank 1 through a gear structure; the rotating tube 7 and the rotating rod 6-4 are connected by a pulley structure 9; the heating zone is provided with a heater 4 and a temperature sensor 5; the drive motor 8, the heater 4 and the temperature sensor 5 are all electrically connected to a controller 17 located on the side wall of the mixing tank 1.

[0019] To facilitate the blowing and removal of residual materials inside the equipment, an induced draft fan 13 is installed at the top of the mixing tank 1. The air outlet of the induced draft fan 13 is connected to one end of the connecting pipe 14, and the other end of the connecting pipe 14 is connected to the top of the rotating pipe 7 through a rotary joint. Multiple air jet pipes are also provided on the rotating pipe 7 located in the mixing zone. Multiple air outlets are provided on the air jet pipes. A bypass port is provided on the connecting pipe 14. The bypass port is connected to the air inlet 6-6 located at the top of the cylinder 6-1 through a ventilation hose 15.

[0020] When drying and heating the material in the mixing zone, an exhaust port 16 is provided on the top of the mixing tank 1 to facilitate the discharge of moisture from the material, and a filter screen is provided at the exhaust port 16.

[0021] To improve the mixing efficiency between materials, multiple mesh plates 11 are also installed on the rotary tube 7.

[0022] In consideration of the principle of energy conservation, insulation cotton 18 is provided on the side wall of mixing tank 1.

[0023] The specific working principle of this utility model is as follows: When it is necessary to mix materials, the temperature threshold of the heating zone is first set. The temperature sensor 5 transmits the measured temperature value to the controller 17 in real time. When the temperature in the heating zone is lower than the set temperature threshold, the controller 17 starts the heater 4. When the temperature in the heating zone is higher than the set temperature threshold, the controller 17 turns off the heater 4.

[0024] Next, start the drive motor 8 and control the drive motor 8 to a slower speed through the controller 17. Open the cover plate 6-3 in the feeding assembly 6 and pour the material into the feeding bin 6-2. The crushing roller 6-5 will crush the agglomerated material and then the material will fall into the mixing zone. After the feeding is completed, close the cover plate 6-3 and then control the drive motor 8 to rotate quickly to mix the material.

[0025] Based on experience, after mixing is complete, open the solenoid valves at the discharge port 3 and control the drive motor 8 to rotate and discharge the material, then collect the discharged material. Next, place a separate container at the discharge port, start the induced draft fan 13 to purge the cylinder 6-1 and the inside of the tank to discharge any remaining material, then turn off all electrical equipment and close the valves at the discharge port 3.
