Description

Technical Field

[0001] The utility model relates to the field of rice grinding equipment, and particularly relates to a grinding device for deep processing of germinated rice. Background Art

[0002] Germinated rice is a kind of rice that retains the germ part of the rice, and the other parts are exactly the same as white rice. After the germinated rice is finely ground, it presents a unique delicate texture. During the grinding process, the rotation speed and pressure of the machine are strictly controlled to ensure that the germ part is not damaged while removing the excess rice bran. In this way, the nutritional components of the germinated rice are retained to the greatest extent.

[0003] However, the current grinding process of germinated rice still has deficiencies and mainly relies on traditional methods, resulting in relatively limited grinding effects. Specifically, the traditional grinding method lacks the ability of multi-angle grinding. During the grinding process, it often can only perform single grinding. This rough processing method is difficult to meet the requirements of production standards, and often there are situations where the ground rice powder particles are uneven and the texture is rough.

[0018] 1. During the operation of this application, the operator introduces germinated brown rice into the feed pipe through the funnel-shaped feed cover. Inside the feed pipe, the germinated brown rice first undergoes preliminary crushing by the first rotating cutter. The preliminarily crushed germinated brown rice then flows into the connecting cylinder and enters the diversion pipe, where the second rotating cutter performs secondary crushing on the germinated brown rice. The germinated brown rice after secondary crushing enters two relatively rotating grinding rollers through the diversion cover for final grinding. In summary, by the step of first crushing the germinated brown rice, it can be ensured that the particles of the processed germinated brown rice powder are uniform and the larger particles are fully broken. This makes it easier and more uniform to grind the germinated brown rice into fine powder in the subsequent grinding stage, thereby improving the uniformity and fineness of the final powder. The subsequent grinding not only improves the grinding efficiency but also reduces the burden on the grinding machine, making the grinding process more efficient and causing relatively less wear to the equipment. This helps to better release the nutrients in the germinated brown rice and thus improve the quality of the powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment:

[0033] A grinding device for deep processing of germinated rice includes a frame body 10, the frame body 10 includes a main frame body 110 and a support frame 120, the support frame 120 is screwed on the top surface of the main frame body 110, and a feeding component 60 is arranged at the top of the support frame 120;

[0034] The feeding component 60 includes a feeding pipe 620 and a first rotary cutter 630. The feeding pipe 620 is fixed inside the support frame 120, the first rotary cutter 630 is clamped in the inner wall of the feeding pipe 620, a guiding component 70 is arranged at the bottom of the feeding pipe 620, a grinding component 40 installed on the top of the frame body 10 is arranged at the bottom of the guiding component 70, the grinding component 40 is powered by a driving component 20 arranged at one end of the frame body 10, and a collecting component 90 is also arranged inside the main frame body 110.

[0035] It should be noted that before the grinding work is carried out, the staff pours the germinated rice into the feeding component 60, and the first rotary cutter 630 in the feeding pipe 620 first crushes the germinated rice, thereby improving the grinding efficiency. The crushing initially breaks the larger particles, making the subsequent grinding process more efficient and reducing the burden on the grinder. Among them, the prior crushing can decompose the germinated rice into smaller and more uniform particles, which helps to obtain more uniform fine powder during grinding. The rotation speed of the first rotary cutter 630 should also be set according to the actual situation and adjusted according to the flow rate of the germinated rice flowing through the inside of the feeding pipe 620.

[0036] Combined with the accompanying drawings of the specification Figures 1 - 5As shown, the feeding component 60 further includes a feeding cover 610. The feeding cover 610 is funnel-shaped. The small-diameter end of the feeding cover 610 is connected to the feeding pipe 620. A connecting component 50 is further provided between the feeding pipe 620 and the guiding component 70. The connecting component 50 includes a connecting cylinder 510 and a tightening handle 520. One end of the connecting cylinder 510 is sleeved on the bottom of the feeding pipe 620, and the other end of the connecting cylinder 510 is sleeved on the guiding component 70. The tightening handle 520 is installed on the connecting cylinder 510 for fixing the connection at both ends of the connecting cylinder 510.

[0037] It should be noted that the material of the feeding cover 610 is usually selected as plastic or metal materials that are wear-resistant and have a certain elasticity to ensure that it can maintain a good shape and function during long-term use. The inner wall of the feeding cover 610 is designed with a smooth surface to reduce the frictional resistance of the material during feeding, thereby improving the feeding efficiency. To further ensure the stability and reliability of the feeding component 60, sealing rings can also be provided at the connections between the connecting cylinder 510 and the feeding pipe 620 and the guiding component 70, thereby effectively preventing material leakage and ensuring that the equipment will not cause environmental pollution or equipment damage due to material leakage during operation.

[0038] Combined with the accompanying drawings of the specification Figures 1 - 5 As shown, the guiding component 70 includes a guiding pipe 710 and a guiding cover 720. The guiding pipe 710 is sleeved on the bottom of the connecting cylinder 510. The guiding cover 720 is connected to the bottom of the guiding pipe 710. A second rotating cutter 730 for secondary shredding is further provided inside the guiding pipe 710. The grinding device includes two grinding rollers 410. The two grinding rollers 410 are installed on the top of the main frame 110 and are arranged on a fixed plate. Among them, the same sides of the two grinding rollers 410 are connected to the driving component 20 through a power transmission component, and the two grinding rollers 410 rotate towards each other.

[0039] It should be noted that the two grinding rollers 410 are powered by a power transmission component. The power transmission component can be a belt with a tension pulley or a chain with a gear. The power transmission component transmits power to the two grinding rollers 410 through a transmission shaft, enabling the two grinding rollers 410 to rotate towards each other synchronously. According to the actual situation, the staff can also provide uneven grinding teeth on the surface of the grinding rollers 410 to increase the grinding effect, and the gap between the two grinding rollers 410 can also be adjusted by the installation position of the grinding rollers 410 to meet the grinding requirements of materials with different particle sizes.

[0040] Combined with the accompanying drawings of the specification Figures 1 - 5As shown, the driving component 20 includes a carrier 210. A driving motor 220 is disposed on the top surface of the carrier 210. The driving shaft of the driving motor 220 is rotationally connected to the power transmission component. A protective plate 230 is further disposed on the top of the driving motor 220. The protective plate 230 is detachably connected to the carrier 210.

[0041] It should be noted that the driving motor 220 is the power core of the entire grinding device, and its stability and reliability are crucial. The setting of the carrier 210 is to ensure the stable installation of the driving motor 220 and facilitate the maintenance and replacement of the motor. The function of the protective plate 230 is to prevent dust and debris generated during the grinding process from entering the interior of the motor, thereby extending the service life of the motor. The protective plate 230 and the carrier 210 are detachably connected, which is convenient for quick disassembly for cleaning or replacing the motor when needed.

[0042] Specifically, during actual use, the staff can adjust the rotation speed of the driving motor 220 according to the type of germinated rice and the required grinding particle size. The rotation speed adjustment of the driving motor 220 can be achieved through the speed adjustment knob on the motor or through an external frequency converter. In addition, to ensure the continuity and stability of the grinding process, the driving motor 220 is usually equipped with an overload protection device. Once the motor load exceeds the set value, the protection device will automatically cut off the power supply to prevent the motor from being damaged.

[0043] Combined with the accompanying drawings of the specification Figures 1 - 5 As shown, the collection component 90 includes a material baffle box 910, a collection cover 920, and a collection hopper 930. The collection cover 920 is connected to the opening on the top surface of the material baffle box 910. The top opening of the collection cover 920 corresponds to the gap between the two grinding rollers 410. The collection hopper 930 is inclined and disposed at the bottom of the main frame 110 and corresponds to the opening at the lower end of the collection cover 920. One end of the collection hopper 930 extends out through a through groove formed on the wall surface of the main frame 110.

[0044] It should be noted that the setting of the collection component 90 is to ensure that the fine powder generated during the grinding process can be effectively collected and stored. The function of the material baffle box 910 is to initially collect the fine powder falling from between the grinding rollers 410 and connect it to the collection cover 920 through the opening on its top surface to ensure that the fine powder flows smoothly into the collection cover 920. The top opening of the collection cover 920 corresponds to the gap between the grinding rollers 410, enabling the fine powder to directly fall into the collection cover 920, thereby reducing the possibility of the fine powder diffusing in the air and improving the collection efficiency.

[0045] Specifically, the collecting hopper 930 is tilted at the bottom of the main frame 110, corresponding to the opening at the lower end of the collecting cover 920, so that the fine powder can smoothly flow into the collecting hopper 930. One end of the collecting hopper 930 extends out of the through slot provided on the wall of the main frame 110, so as to facilitate the collection of fine powder to be exported to an external storage container.

[0046] Combined with the accompanying drawings Figures 1 - 5 As shown, the end face of the main frame 110 is also provided with a mounting hole, and a fan 30 is installed inside the mounting hole. The end face of the fan 30 facing the material blocking box 910 is a fully open face. The frame 10 also includes a protective frame 130, and at least two of the protective frames 130 are provided, and are respectively installed on both sides of the top surface of the main frame 110. The bottom surface of the main frame 110 is also provided with universal wheels 80, and at least four of the universal wheels 80 are provided, and are respectively provided at the four corners of the bottom surface of the main frame 110.

[0047] It is explained that the fan 30 is provided to further improve the collection efficiency. The end face of the fan 30 is a fully open face to ensure uniform distribution of airflow and prevent fine powder from spreading in the air. The speed of the fan 30 can be adjusted by an external controller to adapt to different working environments and needs. The protective frame 130 is provided to protect the safety of the operator and prevent accidental contact with high-speed rotating parts during operation. The protective frame 130 is usually made of a solid metal material, and its shape and size should ensure that it can effectively prevent human body from contacting the dangerous area. At least two protective frames 130 are provided, which are respectively installed on both sides of the top surface of the main frame 110 to provide all-round protection.

[0048] Specifically, the universal wheels 80 provided on the bottom surface of the main frame 110 greatly improve the mobility and flexibility of the device. At least four universal wheels 80 are provided, and are respectively provided at the four corners of the bottom surface of the main frame 110, so that the device can be easily moved between different workplaces while maintaining stability. The design of the universal wheels 80 should also ensure its load-bearing capacity and durability to adapt to various working environments.

[0049] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
