Description

Technical Field

[0001] This utility model relates to the field of soybean processing technology, and in particular to a soybean powder extraction device. Background Technology

[0002] In the soybean processing industry, extraction is a key process for extracting active ingredients (such as soybean protein, oil, and isoflavones). Traditional soybean powder extraction equipment mostly adopts a fixed stirring structure, which has a limited stirring range and non-adjustable height, resulting in uneven material mixing and low extraction efficiency. At the same time, temperature control relies on jacket heating, which has heating blind spots and is prone to local overheating that damages heat-sensitive components. In addition, material concentration monitoring is mostly done offline by sampling and analysis, which cannot provide real-time feedback and adjustment, making it difficult to ensure product quality stability. These problems result in long extraction times (2-3 hours per extraction), low yield of active ingredients (e.g., soybean protein yield of only 70%-75%), high energy consumption (20%-30% higher energy consumption per unit product than advanced levels), and low automation, making it difficult to meet the large-scale and refined requirements of modern soybean deep processing.

[0003] Therefore, this utility model proposes a soybean powder extraction device to solve the above problems.

When the dual-shaft motor 322 is working, it can control the lifting plate 325 to reciprocate and lift, so that the height of the stirring paddle 31 can be adjusted in real time during the stirring operation, thereby effectively increasing the stirring range of the stirring paddle 31 during stirring.

[0042] A conveying pipe 2 connected to the extraction tank 1 is fixedly installed on the extraction tank 1.

[0043] An annular groove is provided on the outer side of the extraction tank 1, and a surrounding heating assembly 15 is disposed in the annular groove. The surrounding heating assembly 15 includes a resistance wire heating coil and multiple temperature sensors. Multiple temperature sensors are embedded and fixedly installed in the annular groove, and a resistance wire heating coil is fixedly installed in the annular groove. The resistance wire heater and temperature sensors are electrically connected to the control panel 13, which can heat the material in the extraction tank 1 as needed and adjust the heating temperature as needed.

[0044] The feed trough 14 is arranged in a ring and fixedly installed on the top of the extraction tank 1, and the feed trough 14 is connected to the extraction tank 1. Multiple storage tanks 16 are fixedly installed on the top side of the rotating frame 12. Multiple storage tanks 16 are fixedly installed with connecting pipes equipped with metering valves at the bottom. Multiple connecting pipes are connected to the feed trough 14. The feed hopper 121 is fixedly installed on the rotating frame 12, and the discharge end of the feed hopper 121 extends into the feed trough 14.

[0045] The control panel 13 is hinged to the support frame 11 via a damping hinge, and the discharge pipe 101 is fixedly installed at the bottom center of the extraction tank 1 and is equipped with a control valve.

[0046] Specifically, in order to facilitate the direct discharge of processed materials into the mold of the plate and frame filter press, and to facilitate the conveying of the mold so as to facilitate the rapid transfer of materials to the next process, a conveyor belt 111 is provided on the support frame 11, and the conveyor belt 111 is located below the discharge pipe 101.

[0047] Specifically, in order to achieve material turning or discharge auxiliary operation at the discharge pipe 101 position by adjusting the rotation direction of the rotating shaft 3, a spiral conveying roller 301 extending into the discharge pipe 101 is axially fixedly connected to the bottom end of the rotating shaft 3.

[0048] Specifically, in order to prevent material from scattering when adding material into the extraction tank 1 through the feed hopper 121 and the feed trough 14, and to ensure that the normal rotation of the rotating frame 12 is not affected, a retaining ring 122 is fixedly installed on the discharge pipe 101 to make movable sealing contact with the top of the feed trough 14.

[0049] Among them, the concentration monitoring instrument 22 adopts an ultrasonic Doppler flow velocity-concentration monitoring instrument.

[0050] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0051] Working principle: First, the power is turned on. When the extraction of soybean powder is required, the required temperature and stirring parameters are set through the control panel 13. Then, the surround heating component 15 is started, the resistance wire heating coil starts to work, and the temperature sensor monitors and feeds back the temperature data in real time to ensure that the material in the extraction tank 1 is heated to a suitable temperature range. At the same time, the dual-shaft motor 322 drives the rotating shaft 3 to rotate, driving the first stirring paddle 31 and the second stirring paddle 311 to work together. The inclined stirring paddle 31 and the second stirring paddle 311 further improve the mixing efficiency under the action of the reverse tilt setting.

[0052] During the mixing process, the second output shaft of the dual-shaft motor 322 drives the reciprocating screw 324 to rotate, causing the lifting plate 325 to move up and down along the slide bar, thereby dynamically adjusting the height of the mixing paddle 31. This height adjustment mechanism expands the mixing range of the mixing paddle 31, enabling the materials to be mixed more evenly and avoiding over- or under-mixing in local areas.

[0053] During the extraction process, the delivery pump 21 draws liquid from the extraction tank 1 through the delivery pipe 2 and sends it to the concentration monitor 22 for real-time detection. Once the material concentration is detected to reach the preset value, the system will automatically adjust the stirring speed or heating temperature to optimize the extraction effect. At the same time, multiple storage tanks 16 inject the required solvent into the feed tank 14 through the metering valve to ensure the continuity and stability of the extraction process.

[0054] After extraction, the molds of the plate and frame filter press are placed sequentially on the conveyor belt 111 and the conveyor belt 111 is controlled to transport them sequentially to the position below the discharge pipe 101. Then, by adjusting the rotation direction of the rotating shaft 3, the rotating shaft 3 drives the screw conveyor roller 301 to push the material to the discharge pipe 101, and finally discharge it onto the molds of the plate and frame filter press on the conveyor belt 111 below. Under the action of the conveyor belt 111, it is quickly transferred to the next process. The design of the retaining ring 122 effectively prevents the material from scattering during feeding, ensuring the cleanliness and efficiency of the entire operation process.

It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
