Description

Technical Field

[0001] This invention belongs to the field of crushing equipment technology, specifically relating to an energy-saving crushing equipment for modified starch raw materials. Background Technology

[0002] With the rapid development of biotechnology, modified starch has been widely used in the food, pharmaceutical, and industrial fields due to its excellent properties. Corn is the mainstream starch raw material, and most modified starch production processes use corn as the base material. Corn crushing equipment, as a key link in this production process, is of significant importance for improving production efficiency and product quality.

[0003] Traditional corn raw material crushing equipment has many shortcomings in terms of crushing efficiency, energy consumption, and crushing effect. Specifically, since corn kernels need to be separated from germ and endosperm, they need to be initially crushed, then the germ is separated by a germ screening machine, and finally the endosperm is sent to a grinder for crushing. This results in corn kernel crushing requiring at least three processes, which not only significantly reduces crushing efficiency but also increases energy consumption and crushing costs, failing to meet the requirements of modern industry for high efficiency and high quality.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an energy-saving crushing equipment for modified starch raw materials.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0021] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0022] like Figures 1-10 As shown, an energy-saving crushing device for modified starch raw materials according to one embodiment of the present invention includes an outer chamber 10, an intermediate chamber 20, a crushing roller 30, and a drive motor 40, all designed with a coaxial structure. The intermediate chamber 20 is fixedly installed inside the outer chamber 10. The top of the intermediate chamber 20 extends through to the top of the outer chamber 10 and is equipped with a feed hopper 21, which facilitates the addition of whole corn kernels to be crushed. The crushing roller 30 is rotatably installed inside the intermediate chamber 20. A discharge channel is reserved between the inner wall of the intermediate chamber 20 and the outer wall of the crushing roller 30, allowing whole corn kernels to enter the discharge channel and fall freely within it. The drive motor 40 is fixedly installed above the intermediate chamber 20, and its output end is fixed to the crushing roller 30, enabling the drive motor 40 to drive the crushing roller 30 to rotate inside the intermediate chamber 20.

[0023] like Figure 3-6As shown, a first crushing structure is fixedly installed on the outer wall of the crushing roller 30. The first crushing structure includes a crushing boss 33, which is fixedly installed on the outer wall of the crushing roller 30 near the top. A gap is reserved between the outer wall of the crushing boss 33 and the inner wall of the intermediate chamber 20. The upper end face of the crushing boss 33 has a "sloping back" shape, which can guide the whole corn kernels that have entered the feeding channel into the gap. The gap only allows the crushed corn kernels to pass through. That is to say, after the whole corn kernels are guided into the gap, they can be initially crushed by the rotation of the crushing roller 30.

[0024] Among them, a number of protruding nails 331 are provided on the outer wall of the crushing boss 33, and the number of protruding nails 331 can effectively ensure the crushing effect of the initial compression.

[0025] Specifically, after the whole corn kernels fall freely into the feeding channel, they will enter the gap under the guidance of the "sloping back" shaped structure on the upper end face of the crushing boss 33. At this time, the drive motor 40 drives the crushing roller 30 to rotate continuously, so that the crushing boss 33 can crush the whole corn kernels in a spiral compression, breaking the whole corn kernels into germ particles and endosperm particles, and then smoothly pass through the gap and continue to fall.

[0026] like Figure 6 As shown, an air extraction port 301 is provided between the inner and outer walls of the crushing roller 30, located below the first crushing structure. An air blowing port 231 is provided between the inner and outer walls of the intermediate chamber 20, directly opposite the air extraction port 301. The airflow blown out through the air blowing port 231 can enter the interior of the crushing roller 30 through the air extraction port 301. Because corn germ has a low density and small volume, the weight of germ particles is less than that of endosperm particles. When germ particles and endosperm particles fall between the air blowing port 231 and the air extraction port 301, the weight difference allows the airflow to blow the germ particles into the interior of the crushing roller 30, achieving preliminary separation of germ and endosperm.

[0027] The air extraction port 301 and the feed port 201 are both designed to be inclined upwards at an angle of 30°-60°. This upward inclination is to prevent endosperm particles from accidentally entering the crushing roller 30 through the air extraction port 301. Since the air pressure at the air blowing port 231 is relatively high, endosperm particles cannot enter, thus effectively ensuring the separation effect.

[0028] Specifically, such as Figure 3 and Figure 6 As shown, an annular housing 23 is fixedly installed on the outside of the air inlet 231. The air inlet 231 is connected to the inside of the annular housing 23. An airflow circulation mechanism is provided between the inside of the crushing roller 30 and the annular housing 23.

[0029] The airflow circulation mechanism includes a fan 35, a connecting shaft tube 38, and a connecting bushing 64. A partition 34 is fixedly installed near the top of the crushing roller 30, dividing the interior of the crushing roller 30 into an upper chamber and a lower chamber. The fan 35 is fixedly installed above the partition 34, with its output end connected to the interior of the upper chamber and its input end connected to the interior of the lower chamber. A fan hood 351 is also fixedly installed at the input end of the fan 35, enabling uniform suction. During the primary crushing process, some starch dust is inevitably generated. This dust is blown into the crushing roller 30 along with the germ particles and then collected by the fan hood 351, achieving separation of the starch dust.

[0030] The connecting shaft tube 38 is fixedly installed on the top of the crushing roller 30. The top end of the connecting shaft tube 38 is fixedly connected to the output end of the drive motor 40 through a coupling. The drive motor 40 drives the crushing roller 30 to rotate through the connecting shaft tube 38.

[0031] like Figure 8 and Figure 9 As shown, the connecting shaft tube 38 is connected to the interior of the upper chamber, and multiple sets of air outlets 381 are opened on the connecting shaft tube 38. The connecting bushing 64 is rotatably mounted on the connecting shaft tube 38, and the connection between the two is sealed with a sealing ring. A cavity is reserved inside the connecting bushing 64, and the air outlets 381 are completely located inside the cavity. The interior of the cavity is connected to the interior of the connecting shaft tube 38 through the air outlets 381, and then to the interior of the upper chamber. A pair of circulation pipes 60 are fixedly installed on both sides of the connecting shaft sleeve 64, and the interior of both circulation pipes 60 is connected to the interior of the cavity. The airflow blown from the output end of the fan 35 first enters the interior of the connecting shaft tube 38, then enters the interior of the cavity through the air outlets 381, and then enters the interior of the pair of circulation pipes 60. The end of a pair of circulation pipes 60 away from the connecting sleeve 64 is connected to the inside of the annular housing 23. That is, the airflow blown out by the output end of the fan 35 can eventually enter the inside of the annular housing 23 through a pair of circulation pipes 60 and be blown out again through the air outlet 231 to achieve airflow circulation.

[0032] Among them, such as Figure 6 and Figure 7As shown, the circulation pipeline 60 includes a starch collection box 61, a first connecting pipe 62, and a second connecting pipe 63. The first connecting pipe 62 is fixedly connected between the starch collection box 61 and the connecting sleeve 64, and the second connecting pipe 63 is fixedly connected between the starch collection box 61 and the annular housing 23. A filter element 611 is fixedly installed at the bottom inside the starch collection box 61, which can filter starch dust in the airflow. One end of the second connecting pipe 63 extends into the interior of the filter element 611. The airflow inside the upper chamber can first enter the starch collection box 61 through the first connecting pipe 62, and after being filtered and collected by the filter element 611, it enters the annular housing 23 through the second connecting pipe 63. This allows for the real-time removal of starch dust in the airflow during the airflow circulation process, preventing dust overflow and improving the environmental performance of the equipment.

[0033] It is worth noting that an outlet 612 is fixedly installed on one side of the starch collection box 61 near the bottom. The outlet 612 can be connected to an air pump (not shown in the figure) to suck up and clean the starch dust collected inside the starch collection box 61. An electric control valve is fixedly installed on the outlet 612 to control its closure. After each use of the equipment, the electric control valve can be opened and the air pump connected to extract the dust adhering to the inside of the starch collection box 61 and the surface of the filter element 611 and discharge it into the outer chamber 10. In addition, during the extraction process, some airflow will enter the interior of the filter element 611 through the second connecting pipe 63 to achieve backflushing cleaning of the filter element 611, ensuring the effectiveness of the filter element 611 when it is reused.

[0034] like Figure 2 and Figure 6 As shown, a support shaft tube 31 is fixedly installed at the bottom of the crushing roller 30, which drives the support shaft tube 31 to rotate during the rotation of the crushing roller 30. A second crushing structure is provided between the support shaft tube 31 and the intermediate chamber 20. Specifically, the second crushing structure includes an upper grinding seat 22, which is fixedly installed at the bottom of the intermediate chamber 20. A discharge port 201 is also provided at the bottom of the intermediate chamber 20. The support shaft tube 31 passes through the discharge port 201 and a lower grinding seat 32 that matches the upper grinding seat 22 is fixedly installed thereon. The lower grinding seat 32 can rotate with the support shaft tube 31. The lower grinding seat 32 and the upper grinding seat 22 cooperate to grind the crushed corn kernels.

[0035] The diameter of the discharge port 201 is larger than the diameter of the support shaft tube 31, meaning there is a gap between the outer wall of the support shaft tube 31 and the inner wall of the discharge port 201, which allows the pre-crushed endosperm particles to pass through.

[0036] During operation, the pre-crushed endosperm particles fall to the bottom of the feeding channel and enter the space between the lower grinding seat 32 and the upper grinding seat 22 through the aforementioned gap. The lower grinding seat 32 then grinds them into powder, which finally falls into the outer chamber 10. In this way, the equipment completes the processing steps of crushing corn kernels, separating the germ, and grinding them into powder. These processing steps are interconnected and do not interfere with each other, achieving efficient crushing of corn raw materials. Furthermore, it only requires one drive system, saving energy and significantly reducing the production cost of modified starch.

[0037] It is worth noting that during the continuous crushing and separation of germ, the airflow blown out of the air blowing port 231 enters the interior of the crushing roller 30 through the air extraction port 301. In this way, a closed air curtain can be formed inside the feeding channel to prevent the starch dust generated during crushing and grinding from overflowing, thereby improving the environmental performance of the equipment during operation.

[0038] As the airflow blows germ particles into the crushing roller 30, it also blows endosperm particles no larger than germ particles into the crushing roller 30. However, the blown-in endosperm particles are relatively small. Therefore, a secondary separation component is installed inside the crushing roller 30. The secondary separation component is located below the air extraction port 301 and is used to separate germ particles and smaller endosperm particles.

[0039] Specifically, the secondary separation component includes a filter hopper 36, which is fixedly installed inside the intermediate chamber 20 near the bottom. The filter hopper 36 has an inverted conical design. The pore size of the filter hopper 36 is smaller than the outer diameter of the germ and larger than the outer diameter of the endosperm, which is smaller than the weight of the germ. In other words, smaller endosperm particles can fall through the filter hopper 36.

[0040] like Figure 5 and Figure 6 As shown, the bottom of the intermediate hopper 20 has multiple sets of return ports 302, which are connected to the inside of the discharge channel. Smaller endosperm particles falling through the filter hopper 36 can enter the bottom of the discharge channel through the return ports 302, and finally enter the space between the upper grinding seat 22 and the lower grinding seat 32 through the discharge port 201 for grinding, so as to grind the smaller endosperm particles into powder.

[0041] The top of the support shaft tube 31 extends into the interior of the intermediate chamber 20 and connects to the interior of the filter hopper 36. Since the germ particles cannot pass through the filter hopper 36, they eventually fall into the filter hopper 36, then enter the support shaft tube 31, and are discharged through the support shaft tube 31. This allows for secondary separation of the germ particles and endosperm particles, ensuring efficient separation of germ and endosperm. Furthermore, the endosperm particles separated in this secondary process can be automatically processed without any other intervention, significantly simplifying the processing of modified starch raw materials and saving production costs.

[0042] Among them, such as Figure 6 As shown, a guide platform 37 is fixedly installed above the filter hopper 36. The guide platform 37 has a conical design, and its lower end is located inside the filter hopper 36. The germ particles and endosperm particles blown into the crushing roller 30 will first fall onto the guide platform 37 and flow towards the edge on the guide platform 37. This allows the germ particles and endosperm particles to fall evenly from the edge onto the filter hopper 36 and roll evenly downwards on the filter hopper 36. During the rolling process, the germ particles and endosperm particles are separated. This can effectively improve the separation effect and avoid clogging, ensuring continuous and stable operation.

[0043] It is worth noting that, since the crushing roller 30 is rotating during the secondary separation process, there is a certain centrifugal force and inertial force. Through the action of centrifugal force and inertial force, the germ particles and endosperm particles can fall spirally on the filter hopper 36, giving the endosperm particles sufficient separation time, thereby improving the secondary separation effect.

[0044] A discharge conduit 11 is fixedly installed at the bottom of the outer chamber 10, and a first solenoid valve 111 is fixedly installed on the discharge conduit 11. The first solenoid valve 111 is used to control the closing of the discharge conduit 11. During the crushing process, dust is generated as the powder falls into the outer chamber 10, so the first solenoid valve 111 is in the closed state. After the crushing process is completed and the material has been left to stand for twenty minutes to ensure that the dust has settled to the bottom, the first solenoid valve 111 is opened to allow the ground starch raw material inside the outer chamber 10 to be discharged. This avoids both material waste and environmental pollution.

[0045] Among them, such as Figure 2 As shown, a lever 311 is also fixedly installed on the support shaft tube 31. The lever 311 can be used to stir the starch raw material inside the outer chamber 10 during the process of discharging the starch raw material, so as to assist the starch raw material to be discharged quickly and prevent blockage.

[0046] A collection box 50 is fixedly placed directly below the outer chamber 10. The bottom of the support shaft tube 31 passes through the discharge conduit 11 and is rotatably connected to the collection box 50. The inside of the support shaft tube 31 is connected to the inside of the collection box 50. After the germ particles enter the inside of the support shaft tube 31, they eventually fall into the collection box 50, thus collecting the germ particles and facilitating subsequent processing.

[0047] When using, such as Figure 2 and Figure 10As shown, whole corn kernels enter the feeding channel through the feed hopper 21 and fall freely inside the channel. Upon passing the crushing boss 33, they are crushed into germ and endosperm particles, and continue falling. When the germ and endosperm particles fall between the air inlet 231 and the air outlet 301, the weight difference allows the airflow to blow the germ particles into the crushing roller 30, achieving initial separation of the germ and endosperm. The germ particles and smaller endosperm particles blown into the crushing roller 30 first fall onto the guide platform 37 and flow towards the edge, allowing them to fall evenly from the edge onto the filter hopper 36 and roll evenly downwards. The smaller endosperm particles fall through the filter hopper 36 and enter the bottom of the feeding channel through the return port 302, finally entering the space between the upper grinding seat 22 and the lower grinding seat 32 for grinding through the discharge port 201. Since the germ particles cannot pass through the filter hopper 36, they will eventually fall into the filter hopper 36, then enter the support shaft tube 31, and be discharged into the collection box 50 through the support shaft tube 31.

[0048] All germ particles eventually enter the space between the lower grinding seat 32 and the upper grinding seat 22 through the feed port 201 to be ground into powder, forming the raw material of modified starch. After the crushing process is completed, the material is left to stand for 20 minutes before the first solenoid valve 111 is opened to allow the modified starch raw material to flow out through the discharge pipe 11, thus completing all crushing processes in one go.

[0049] Compared with the prior art, the modified starch raw material energy-saving crushing equipment of the present invention can sequentially complete the crushing and grinding of corn raw materials between the intermediate chamber 20 and the crushing roller 30. After crushing and before grinding, the germ is efficiently separated by the weight difference between the germ and the endosperm with the help of circulating airflow. Thus, the crushing equipment can complete the crushing, separation and grinding operations in one go, and can work continuously and efficiently, greatly improving crushing efficiency, saving energy consumption and reducing production costs.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
