[0002] Soybean flour is a high-protein food that is loved by many people. However, the production process of soybean flour is very complicated. The first step in the production of soybean flour is to grind soybeans into small pieces, then grind the small pieces into soy milk, and then sterilize the soy milk to ensure hygiene. The second purpose of sterilization is to remove the beany smell and make the soy aroma more intense. After sterilization, the soy milk is dried into powder in a drying tower.

[0003] However, existing sterilization devices still have the following technical problems when in use:

[0004] The existing sterilization process mainly involves circulating hot air at 120-160℃ to treat soybean flour for 30-60 minutes. After sterilization, because soybean flour contains a certain amount of moisture, it will adhere to the inner wall of the sterilization device. The current sterilization device cannot effectively scrape off the inner wall of the sterilization device to drain the soybean flour inside and avoid waste.

[0005] Therefore, a sterilization device for soybean flour processing is proposed to solve the above-mentioned problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A sterilization device for processing soybean flour includes a sterilization chamber 1. A soybean flour adding hopper 2 is fixed to the upper left side of the sterilization chamber 1. An air inlet pipe 3 is fixed to the left side of the sterilization chamber 1. An electric heating device 4 is fixed to the left end of the air inlet pipe 3. The electric heating device 4 is equipped with a temperature control device, which can control and adjust the heating temperature. A blower 5 is fixed inside the air inlet pipe 3. An air outlet pipe 6 is fixed to the right side of the sterilization chamber 1. A filter screen 7 is fixed inside both the air inlet pipe 3 and the air outlet pipe 6. The airflow blown into the sterilization chamber 1 by the blower 5 is heated to sterilize the soybean flour stored inside.

[0027] The upper side of the sterilization chamber 1 is rotatably connected to the rotating pipe 8 via a bearing. The lower side of the rotating pipe 8 is fixed to the regulating box 9. The regulating box 9 is equipped with an regulating mechanism. The left and right ends of the regulating mechanism are both fixed with stirring plates 10. During the sterilization of soybean powder, the two stirring plates 10 do not contact the inner wall of the sterilization chamber 1. This is to continuously stir the soybean powder so that the hot air can fully contact the soybean powder and increase the sterilization effect. When it is necessary to discharge the soybean powder, the regulating mechanism drives the two stirring plates 10 to move to both ends so that the side walls of the two stirring plates 10 contact the inner wall of the sterilization chamber 1. This can scrape the soybean powder adhering to the inner wall of the sterilization chamber 1 and prevent soybean powder residue inside. The lower side of the sterilization chamber 1 is provided with an outlet, and the internal thread of the outlet is connected to a sealing plug 11.

[0028] The upper side of the sterilization chamber 1 is fixed to the outside of the rotating tube 8. The rotating tube 8 is rotatably connected to the side wall of the chamber 12. Inside the chamber 12, at the right end of the rotating tube 8, a transmission mechanism is provided to drive the rotating tube 8 to rotate.

[0029] The sterilization chamber 1 has symmetrical vertical plates 13 fixed on its lower side, and a horizontal plate 14 is fixed between the two vertical plates 13. A holding trough 15 is provided at the upper end of the horizontal plate 14. The holding trough 15 is used to hold the sterilized soybean powder.

[0030] The adjusting mechanism includes a vertical rod 16, which is slidably disposed inside the rotating tube 8. The lower end of the vertical rod 16 extends into the adjusting box 9 and is fixed with a pressing block 17. Symmetrical wedge blocks 18 are slidably connected inside the adjusting box 9. Horizontal rods 19 are fixed to the opposite sides of the two wedge blocks 18. The other ends of the two horizontal rods 19 are fixedly connected to the stirring plate 10. The two horizontal rods 19 are slidably connected to the side walls of the adjusting box 9. The left and right sides of the pressing block 17 are in contact with the side walls of the wedge blocks 18. A first spring 20 is sleeved on the outside of the horizontal rod 19. One end of the first spring 20 is connected to the adjusting box. The inner wall of 9 is fixedly connected, and the other end of the first spring 20 is fixedly connected to the side wall of the wedge block 18. The upper end of the tube wall of the rotating tube 8 is threaded with symmetrical limiting bolts. The two limiting bolts are engaged with the vertical rod 16 at their closest ends. When the position of the stirring plate 10 needs to be adjusted, the vertical rod 16 is moved downward. The vertical rod 16 drives the lower end of the extrusion block 17 to move downward and extrude the two wedge blocks 18. The two wedge blocks 18 move to both ends. The two wedge blocks 18 drive the horizontal bar 19 on the side wall and the stirring plate 10 to move to both ends until the two stirring plates 10 contact the inner wall of the sterilization box 1.

[0031] The transmission mechanism includes a motor 21, which is fixedly connected to the upper side of the housing 12. A transmission rod 22 is fixedly attached to the output end of the motor 21. A first pulley is fixedly sleeved on the wall of the transmission rod 22. A second pulley is fixedly attached to the wall of the rotating tube 8. The first pulley is rotatably connected to the second pulley via a belt.

[0032] A fixed tube 23 is fixed to the wall of the rotating tube 8. Strip plates 24 are fixed to the left and right sides of the fixed tube 23. A cavity is opened inside the strip plate 24. A slider 25 is slidably connected inside the cavity. A connecting rod 26 is fixed to the side wall of the slider 25. The other end of the connecting rod 26 extends through the side wall of the cavity to the outside and is fixed with a cleaning brush 27. A second spring 28 is sleeved on the outside of the connecting rod 26. One end of the second spring 28 is fixedly connected to the inner wall of the cavity, and the other end of the second spring 28 is fixedly connected to the side wall of the slider 25. During the sterilization of soybean powder, some soybean powder will inevitably adhere to the surface of the filter screen 7. The rotating tube 8 drives the fixed tube 23 to rotate, and the fixed tube 23 drives the connecting rod 26 and the cleaning brush 27 on the side wall to rotate, thus cleaning the filter screen 7.

[0033] The two stirring plates 10 are adapted to the inner cavity of the sterilization chamber 1.

[0034] Working principle:

[0035] In use, soybean powder is added into the sterilization chamber 1 through the soybean powder adding hopper 2. The electric heating device 4 and the blower 5 are turned on, and the temperature of the blown air is adjusted to control 120-160 degrees Celsius. Sterilization is continued for 30-60 minutes. The motor 21 is turned on, and the motor 21 drives the transmission rod 22 at the output end to rotate. The transmission rod 22 drives the first pulley on the rod wall to rotate. The first pulley drives the second pulley to rotate through the belt. The second pulley drives the rotating tube 8 to rotate. The rotating tube 8 drives the regulating box 9, the crossbar 19 and the stirring plate 10 to rotate. At this time, the stirring plate 10 does not contact the inner wall of the sterilization chamber 1. The soybean powder is constantly turned by the rotation of the two stirring plates 10 to ensure that the soybean powder is heated evenly and can be sterilized better.

[0036] During the stirring process, when some soybean powder adheres to the side wall of the filter screen 7 and affects the air intake, the rotating pipe 8 drives the fixed pipe 23, the strip plate 24, the connecting rod 26 and the cleaning brush 27 to rotate, so as to treat the soybean powder adhering to the side wall of the filter screen 7.

[0037] When the soybean powder sterilization is complete and needs to be discharged from the sterilization chamber 1, open the lower sealing plug 11, move the vertical rod 16 downward, and the vertical rod 16 drives the lower extrusion block 17 to move downward. The extrusion block 17 extrudes the two wedge blocks 18, and the wedge blocks 18 drive the two horizontal rods 19 and the stirring plate 10 to move to both ends, so that the two stirring plates 10 contact the inner wall of the sterilization chamber 1. The transmission mechanism continues to drive the rotating tube 8 to rotate, so that the two stirring plates 10 continuously scrape the wall of the sterilization chamber 1, quickly discharge the soybean powder, and avoid waste caused by internal residue.
