Description

Technical Field

[0001] The present invention relates to the technical field of deep processing equipment for beans, and in particular to a system integrating bean soaking and grinding. Background Art

[0002] Bean agricultural products are rich in nutrients and can be processed into deep - processed bean products such as tofu, soymilk, and soy milk. During the deep processing of bean agricultural products, the beans generally need to be ground and then further processed. Before grinding, the beans generally need to be soaked to make them fully absorb water and then ground. Usually, soaking and grinding are carried out separately, so at least two devices are required. After soaking is completed in the soaking device (such as a bean soaking cylinder, a heating device can be set inside the bean soaking cylinder to soak in water at a certain temperature, and a stirring structure can also be set to stir during the soaking process to improve the soaking efficiency), it needs to be exported and then transferred to the grinding device (such as a grinder. Inside the grinder, the soaked beans are generally ground into a slurry by high - speed rotating blades and then exported). The operation steps are relatively numerous, and the beans are generally exposed to the outside during the transfer process, and foreign matters may be mixed in. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a system integrating bean soaking and grinding, which solves the problems of more processing steps for bean soaking and grinding in the prior art and possible mixing of foreign matters during the transfer process.

[0004] According to an embodiment of the present invention, a system for soaking and grinding beans includes an outer cylinder body, and an inner cylinder body fixedly arranged inside the outer cylinder body. A discharge pipe is arranged at the bottom of the outer cylinder body. A connecting cylinder is fixedly connected to the inner cylinder body and extends upward through the outer cylinder body. A feed hopper is also fixedly connected to the connecting cylinder. A heating assembly is further arranged inside the outer cylinder body. A mounting shaft vertically arranged inside the inner cylinder body penetrates through the connecting cylinder. A first driver for driving the mounting shaft to rotate is connected above the connecting cylinder. A rotating disk located inside the inner cylinder body is fixedly connected to the mounting shaft. An annular fixed disk is inwardly protruded from the inner wall of the inner cylinder body. The rotating disk is located inside the annular structure of the fixed disk. An annular grinding gap that is larger at the top and smaller at the bottom is arranged between the rotating disk and the fixed disk. A plurality of first through holes are arranged at the bottom of the inner cylinder body, and a plurality of second through holes located above the fixed disk are arranged at the upper end. A circulation assembly for circulating liquid between the first through holes and the second through holes is arranged inside the outer cylinder body. Beans enter the connecting cylinder from the feed hopper, then fall into the inner cylinder body, and water is added from the feed hopper to submerge the beans. At this time, the water will also enter the outer cylinder body. The water is heated into hot water by the arranged heating assembly (heating can be stopped after reaching a certain temperature, such as 50 - 60 °C). At the same time, the circulation assembly can be started to make the water circulate between the inner cylinder body and the outer cylinder body, and soaking can be carried out. After soaking is completed, the soaking water is discharged and grinding water is added again for grinding (or the soaking water can not be discharged and appropriate grinding water can be supplemented for grinding). During grinding, the circulation assembly is in continuous operation, and at the same time, the first driver is started to make the rotating disk rotate. The beans move downward in the grinding gap and are gradually ground fine during the process, then pass through the lower end of the grinding gap and reach the outer cylinder body through the first through holes, and then circulate upward to the second through holes and enter the inner cylinder body. After multiple circulations, a slurry is finally formed. Finally, the first driver and the circulation assembly are stopped, and the slurry is led out through the discharge pipe. The entire soaking and grinding process is carried out in one device, and no foreign matters will be mixed in during the process. Therefore, it is more convenient and efficient, and solves the problem that there are many processing steps for soaking and grinding beans in the prior art and foreign matters may be mixed in during the transfer process.

[0005] Further, an inclined guide plate is fixedly arranged inside the connecting cylinder. The inclined guide plate has a higher end fixedly connected to the connecting cylinder and a lower end separated from the connecting cylinder. The feed hopper is located above the lower end of the inclined guide plate. A gas guide pipe fixedly connected to the higher end of the inclined guide plate and communicating with the space below the inclined guide plate is also fixed on the connecting cylinder.

[0006] Further, the lower end of the mounting shaft penetrates through the rotating disk and is rotatably connected to the bottom of the inner cylinder body. A plurality of third through holes located above the grinding gap are arranged on the upper end surface of the rotating disk. A first spiral extending from inside the rotating disk to below the rotating disk is also fixedly connected to the mounting shaft.

[0007] Further, a second spiral located above the rotating disk is also fixedly connected to the mounting shaft.

[0008] Further, the circulation component includes a pair of third helices disposed inside the outer cylinder and on both sides of the inner cylinder. The third helices are vertically arranged, and two second drivers for driving the two third helices to rotate self are also disposed outside the outer cylinder.

[0009] Further, a pair of first connecting plates are fixedly connected between the outer wall of the lower end of the inner cylinder and the inner wall of the outer cylinder. The lower end portions of the two third helices are respectively rotatably connected to the two first connecting plates, and fourth through holes respectively surrounding the end portions of the corresponding third helices are also disposed on the first connecting plates.

[0010] Further, the circulation component further includes a fourth helix horizontally disposed inside the outer cylinder and below the inner cylinder, and a third driver for driving the fourth helix to rotate self is also disposed outside the outer cylinder.

[0011] Further, the fourth helix includes two helical segments with opposite rotation directions.

[0012] Further, the heating component includes an electric heating tube located below the fourth helix.

[0013] Further, a feeding hopper fixedly connected to the upper end of the annular structure of the fixed disk is also fixedly disposed inside the inner cylinder. All the second through holes are located above the feeding hopper, and the upper end of the rotating disk extends into the feeding hopper.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The soaking and grinding of beans are carried out in one device, and no foreign matters will be mixed in the process. During soaking, the circulation component disposed outside the outer cylinder enables the soaking water to circulate between the inner cylinder and the outer cylinder, which can improve the soaking efficiency. At the same time, the circulation component can also play a role in improving the efficiency during the grinding process. Finally, the soaking and grinding of beans are carried out integrally and efficiently, solving the problems in the prior art that there are many processing steps for soaking and grinding beans and foreign matters may be mixed in the transfer process.

[0023] In an exemplary embodiment, as Figures 1-3As shown in the figure, this embodiment provides a system for integrated soaking and grinding of beans, which includes an outer cylinder 1 and an inner cylinder 2 fixedly arranged inside the outer cylinder 1. An installation frame 3 is also fixedly arranged outside the outer cylinder 1. The upper and lower ends of the outer cylinder 1 are respectively fixed to the installation frame 3 through fixing plates 4. A discharge pipe 5 is arranged at the bottom of the outer cylinder 1 (a valve 6 is arranged on the discharge pipe 5 to control its on-off). A connecting cylinder 7 is fixedly connected to the inner cylinder 2 and extends upward through the outer cylinder 1 to the outside. The connecting cylinder 7 also extends fixedly above the installation frame 3. A feed hopper 8 is fixedly connected to the connecting cylinder 7 to introduce beans and water. A water inlet pipe 9 can also be separately provided to introduce water (soaking water and grinding water). The feed hopper 8 is used to introduce beans. Both the feed hopper 8 and the water inlet pipe 9 are located above the installation frame 3, which is convenient for operation and also makes the whole system more stable. Further, a ring plate 10 can be fixedly connected between the connecting cylinder 7 and the installation frame 3. The ring plate 10 is located above the installation frame 3, which can make the connecting cylinder 7 more stably connected to the installation frame 3 and the overall system has better stability. A heating component is also arranged inside the outer cylinder 1. The heating component can be an electric heating pipe 11. The electric heating pipe 11 is arranged at the bottom of the outer cylinder 1 and is used to heat the soaking water. For example, it can be heated to 50-60 °C, and can stop after reaching the specified temperature and can be heated again when it is lower than the temperature range. An installation shaft 12 is vertically arranged inside the inner cylinder 2 and penetrates through the connecting cylinder 7. A first driver 13 for driving the installation shaft 12 to rotate is connected above the connecting cylinder 7. A rotating disk 14 located inside the inner cylinder 2 is fixedly connected to the installation shaft 12. An annular fixed disk 15 is convexly arranged inward on the inner wall of the inner cylinder 2. The rotating disk 14 is an upwardly convex umbrella-shaped structure. The rotating disk 14 is located inside the annular structure of the fixed disk 15. An annular grinding gap 16 with a larger upper part and a smaller lower part is also arranged between the rotating disk 14 and the fixed disk 15. Beans are introduced into the connecting cylinder 7 through the feed hopper 8 and then fall into the inner cylinder 2. They will not pass through the grinding gap 16 at the position of the fixed disk 15 (the upper end of the grinding gap 16 is larger and can allow some beans to enter, but it becomes smaller and smaller downward, so the beans are intercepted above the grinding gap 16) and are soaked above the grinding gap 16. A number of first through holes are arranged at the bottom of the inner cylinder 2, and a number of second through holes located above the fixed disk 15 are arranged at the upper end. A circulation component for circulating the liquid between the first through holes and the second through holes is also arranged inside the outer cylinder 1, that is, to make the liquid circulate between the inner cylinder 2 and the outer cylinder 1. The added soaking water can enter the outer cylinder 1 through the grinding gap 16 and the first through holes, and the water added during soaking can submerge the second through holes (and also submerge the beans). In this way, when soaking, the circulation component is started to make the soaking water circulate between the inner cylinder 2 and the outer cylinder 1, and the soaking is more efficient.After the soaking is completed, the soaking water is discharged through the discharge pipe 5, and then grinding water is added to conduct grinding (it is also possible not to discharge the soaking water and appropriately supplement the grinding water for grinding). During grinding, the circulating assembly is in continuous operation. At the same time, the first driver 13 is started to make the rotating disk 14 rotate. The beans move downward at the grinding gap 16 and are gradually ground finer during the process, and then pass through the lower end of the grinding gap 16 and reach the outer cylinder 1 through the first through hole, and then circulate upward to enter the inner cylinder 2 through the second through hole. After multiple circulations, a slurry is finally formed. Finally, the first driver 13 and the circulating assembly are stopped, and the slurry is discharged through the discharge pipe 5. The entire soaking and grinding process is carried out in one device, and no foreign matter will be mixed in during the process. Therefore, it is more convenient and efficient, solving the problem in the prior art that there are many steps in the soaking and grinding of beans and foreign matter may be mixed in during the transfer process.

[0024] As Figures 1-3 shown, an inclined guide plate 17 is also fixedly arranged in the connecting cylinder 7. The mounting shaft 12 rotates through the inclined guide plate 17. The inclined guide plate 17 has a higher end fixedly connected to the connecting cylinder 7 and a lower end separated from the connecting cylinder 7. The feed hopper 8 is located above the lower end of the inclined guide plate 17. A gas guide pipe 18 fixedly connected to the higher end of the inclined guide plate 17 and communicating with the space below the inclined guide plate 17 is also fixed on the connecting cylinder 7. During the soaking process, hot steam may surge upward. The inclined guide plate 17 can deflect the hot steam so that most of the hot steam moves obliquely upward after meeting it, and then enters the gas guide pipe 18. More specifically, a plurality of through holes 19 can be provided on the inclined guide plate 17, and a gas collecting hood 20 fixedly covering all the through holes 19. In this way, the hot steam can more easily enter the gas collecting hood 20. The gas guide pipe 18 is connected to the gas collecting hood 20, thereby guiding the hot steam away. An induced draft fan can also be connected to the end of the gas guide pipe 18 outside the connecting cylinder 7 to provide power to more efficiently discharge the hot gas; further, the provided water inlet pipe 9 can be located below the inclined guide plate 17 or above the inclined guide plate 17; the connection between the feed hopper 8 and the connecting cylinder 7 is located above the inclined guide plate 17. The beans enter the connecting cylinder 7 through the feed hopper 8 and finally fall downward through the gap between the lower end of the inclined guide plate 17 and the connecting cylinder 7.

[0025] As Figure 1 、 2As shown, the lower end of the mounting shaft 12 passes through the rotating disk 14 and is rotatably connected to the bottom of the inner cylinder 2. A plurality of third through holes are provided on the upper disk surface of the rotating disk 14 above the grinding gap 16. A first spiral 21 extending from inside the rotating disk 14 to below the rotating disk 14 is also fixedly connected to the mounting shaft 12. The third through holes provided on the upper end of the rotating disk 14 can allow water or finely ground slurry to pass through, but not beans (the aperture of the third through holes is dense and is only used for water and finely ground slurry to pass through, and beans that have not been ground into slurry cannot pass through). The provided first spiral 21 rotates synchronously when the rotating disk 14 operates, generating a pulling effect downward, enabling the liquid to pass downward through the third through holes and enter the rotating disk 14. At the same time, the first spiral 21 also extends below the rotating disk 14, which can also enable the liquid to pass through the grinding gap 16 more efficiently, thereby enabling the grinding to be carried out efficiently. In particular, the provided first spiral 21 can also be structured with a smaller upper part and a larger lower part, so that the pulling effect generated at the lower end is greater and the liquid passes through the grinding gap 16 more smoothly; furthermore, a second spiral 22 located above the rotating disk 14 is also fixedly connected to the mounting shaft 12. The second spiral 22 can generate a downward push when the mounting shaft 12 rotates, thereby enabling the liquid and beans to move downward, enabling the grinding to be carried out efficiently. The provided second spiral 22 can also extend into the connecting cylinder 7. When cleaning is carried out after the subsequent grinding is completed, reversing the mounting shaft 12 can cause the cleaning water to be lifted upward, which can better clean the connecting cylinder 7 as well.

[0026] As Figure 1 , 2 shown, in a further embodiment, a feed hopper 23 fixedly connected to the upper end of the annular structure of the fixed disk 15 is also provided inside the inner cylinder 2. All the second through holes are located above the feed hopper 23. The upper end of the rotating disk 14 extends into the feed hopper 23. The feed hopper 23 can be integral with the fixed disk 15, thus forming a funnel structure with a larger upper part and a smaller lower part inside the inner cylinder 2. In this way, the beans can move downward more efficiently during the grinding process, and the upper end of the rotating disk 14 extends into the feed hopper 23. When rotating, the beans come into contact with the wall surface of the rotating disk 14 downward and then continue to move downward into the grinding gap 16.

[0027] As Figure 1 , 2As shown, the provided circulation component includes a pair of third helices 24 disposed inside the outer cylinder 1 and on both sides of the inner cylinder 2, and a fourth helix 25 horizontally placed inside the outer cylinder 1 and below the inner cylinder 2. The third helices 24 are vertically arranged. Outside the outer cylinder 1, there are also provided two second drivers 26 for driving the two third helices 24 to rotate self - respectively, and a third driver 27 for driving the fourth helix 25 to rotate self - respectively. The provided electric heating tube 11 can also be located below the fourth helix 25. The first driver 13, the second drivers 26, and the third driver 27 can all be drive motors. The third helices 24 and the fourth helix 25 operate on both sides and below the inner cylinder 2 respectively. And the provided fourth helix 25 also includes two helical segments 28 with opposite rotation directions. When the fourth helix 25 operates, it can pull the liquid towards its two ends, and then cooperate with the third helices 24 on both sides, so that the liquid moves upward and then returns to the inner cylinder 2 through the second through - hole, and then moves downward through the grinding gap 16, the third through - hole, and the first through - hole to achieve circulation. Further, a pair of first connecting plates 29 are fixedly connected between the outer wall of the lower end of the inner cylinder 2 and the inner wall of the outer cylinder 1. The lower end portions of the two third helices 24 are respectively rotatably connected to the two first connecting plates 29. In this way, the first connecting plates 29 provide rotational support for the lower ends of the third helices 24, making their operation smoother. And on the first connecting plates 29, there are also provided fourth through - holes respectively surrounding the ends of the corresponding third helices 24. The fourth through - holes allow the liquid to pass through, enabling the circulation to proceed smoothly. Further, the ends of the fourth helix 25 can also be rotatably connected to the inner wall of the outer cylinder 1, which can also make the operation smoother. At the same time, the first connecting plates 29 also make the connection between the lower end of the inner cylinder 2 and the outer cylinder 1 more stable. A pair of second connecting plates 30 can be provided between the middle section of the inner cylinder 2 and the outer cylinder 1. Fifth through - holes are provided on the second connecting plates 30 for the corresponding third helix 24 to pass through as a whole, which can make the connection between the inner cylinder 2 and the outer cylinder 1 more stable.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
