Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices, and in particular relates to a low-temperature ultrafine grinding device for flour products and a use method thereof. Background Art

[0002] Flour products are generally made by mixing wheat flour or other food flour products. Common types include high-gluten flour, medium-gluten flour, and low-gluten flour. During the flour production process, low-temperature ultrafine grinding equipment is required to preserve its nutrients, improve flour quality, and meet special needs.

[0003] The existing low-temperature ultrafine grinding device includes a rotating module, the end of the output shaft of the rotating module is fixedly connected to a rotating shaft, and the rotating shaft passes through the discharge pipe. The outer fixed sleeve of the rotating shaft is provided with a spiral discharge blade and a grinding part. The rotating module drives the grinding part to grind the flour product through the rotating shaft.

[0004] Existing flour grinding devices have certain limitations in the actual production process. The grinding parts therein grind flour products only by rotation, which makes it easy for flour products to accumulate locally or become excessive, reducing the grinding efficiency. At the same time, flour will adhere to the inner wall of the grinding chamber during the grinding process, which not only affects the overall grinding quality of the device, but also reduces the output of flour products.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a low-temperature ultrafine grinding device and a method for using flour products to overcome the shortcomings in current practical applications. Summary of the Invention

[0012] The grinding assembly includes a grinding shaft, a grinding roller, a mounting post and a spring, the grinding shaft is arranged in parallel in the grinding cylinder, the two ends of the grinding shaft are respectively rotatably connected to the sliders on the two adjusting disks, the grinding roller is fixed on the grinding shaft, the outer wall of the grinding roller is equidistantly distributed with grinding pieces, one side of the grinding piece is matched with the grinding grooves equidistantly distributed on the inner wall of the grinding cylinder, the other side of the grinding piece is provided with a notch, the mounting post is vertically slidably arranged in the notch, one end of the mounting post extends into the mounting hole provided on the grinding roller, one end of the mounting post is connected to the spring installed in the mounting hole, and the other end of the mounting post extends to the outside of the grinding piece and is fixedly connected to the scraper;

[0013] The support assembly includes a hydraulic component, a connecting frame, a bottom bracket and a top bracket. The hydraulic component is symmetrically arranged in the production chamber. The output end of the hydraulic component is rotatably connected to the connecting frame fixed to the bottom of the bottom bracket. The top bracket is installed above the bottom bracket. The mounting cylinder is located between the bottom bracket and the top bracket and is rotatably connected to both of them.

[0014] The rotating assembly includes a second motor, a main shaft and a linkage unit. The second motor is fixed in the control box. The main shaft is fixed to the output end of the second motor. One end of the main shaft extends into the production chamber and is connected to a rotating shaft in a mounting cylinder through the linkage unit.

[0015] The linkage unit includes a linkage disk 1, a universal joint, a fixed sleeve, a sliding column and a linkage disk 2. The linkage disk is concentrically fixed on the main shaft, a universal joint is fixed on one side of the linkage disk 1, the linkage disk 2 is concentrically fixed on the rotating shaft, a universal joint is fixed on one side of the linkage disk 2, a fixed sleeve and a sliding column are installed between the two universal joints, and the sliding column and the fixed sleeve are axially slidingly connected.

[0016] As a further technical solution of the present invention, the rotating disk, rotating shaft, mounting cylinder, grinding cylinder and adjusting disk are all concentric, and a square channel connected to each other is provided on one side of the grinding cylinder, and a storage cylinder is installed on one side of the square channel.

[0017] A method for using the low-temperature ultrafine grinding device for flour products as described above comprises the following specific steps:

[0018] 1. The motor drives the screw to rotate. The screw drives the slider to slide in the adjustment slot by rotating and being screwed to the side bracket. The slider drives the milling assembly to move radially and change the axis position of the milling assembly. In the initial state, the axis of the milling component and the axis of the milling cylinder are eccentric, the scraper does not interfere with the inner wall of the milling cylinder, the telescopic lengths of the two hydraulic components are consistent, and the top bracket, bottom bracket and mounting cylinder on the two hydraulic components are all in a horizontal state.

[0019] The second motor drives the main shaft to rotate, and the main shaft drives the linkage disk 1 and the universal joint thereon to rotate. The universal joint on the linkage disk 1 drives the linkage disk 2 to rotate through the fixed sleeve and the sliding column. The linkage disk 2 drives the rotating shaft to rotate. The rotating disk drives the adjusting disk to rotate. The adjusting disk drives the grinding shaft and the grinding roller to rotate eccentrically in the grinding cylinder through the slider. The grinding roller drives multiple grinding parts and scrapers to rotate eccentrically. The eccentrically rotating grinding parts cooperate with the grinding cylinder to achieve ultra-fine grinding of flour products.

[0020] Second, due to the eccentric rotation of the grinding elements, when the slider drives the grinding shaft and grinding roller to move radially, the grinding roller drives multiple grinding elements and scrapers to move radially and change the eccentric distance between the grinding elements and the grinding cylinder. By changing the eccentric distance between the grinding elements and the grinding cylinder, flour products of different specifications enter the grinding area between the two. The scrapers move to a position that contacts the inner wall of the grinding cylinder and scrape off the flour products adhering to the inner wall of the grinding cylinder.

[0021] During the grinding process of the flour product, the two hydraulic components reciprocately change the horizontal height of the two mounting cylinders by reciprocatingly changing the extension length. The two mounting cylinders drive the grinding cylinder and the grinding assembly to tilt reciprocatingly. The reciprocating tilting of the grinding cylinder and the grinding assembly drives the flour product to move axially reciprocatingly in the grinding cylinder.

[0022] 3. When the flour products in the milling cylinder need to be discharged, the control unit drives the scraper to move to a position that conflicts with the inner wall of the milling groove by rotating. The scraper cooperates with the rotating component to discharge the flour products hidden in the milling groove. The support component again changes the telescopic length of the two hydraulic parts and drives the milling parts and the milling cylinder to tilt back and forth. The scraper in the rotating state cooperates with the support component to complete the efficient discharge of the flour products.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The rotating assembly drives the grinding assembly to rotate in the grinding cylinder through the control assembly. The control assembly can change the axial distance between the grinding assembly and the grinding cylinder. This not only facilitates flour products of different specifications to better enter the grinding area between the grinding element and the grinding cylinder, ensuring that the flour products in the grinding cylinder can be better and faster ground, reducing the grinding time and improving the grinding efficiency and grinding quality of the device, but also facilitates the scraper to move to a position that conflicts with the inner wall of the grinding cylinder, so that the scraper can scrape off the flour products adhering to the inner wall of the grinding cylinder and allow them to fall into the grinding area, thereby facilitating the cooperation between the grinding element and the grinding cylinder to complete the ultrafine grinding of the flour products, avoiding excessive adhesion of flour products and affecting the grinding efficiency and grinding quality of the device, and greatly improving the adaptability and flexibility of the device.

[0025] At the same time, in conjunction with the support assembly, the support assembly can reciprocately change the horizontal height of the two mounting cylinders, so that the grinding cylinder and the grinding assembly can tilt reciprocatingly, which facilitates the axial reciprocating movement of the flour product in the grinding cylinder, and facilitates the rotating grinding assembly to quickly and efficiently perform ultra-fine grinding on the flour product, thereby reducing the grinding time of the flour product.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0040] like Figures 1 to 9 As shown, a low-temperature ultrafine grinding device for flour products provided as an embodiment of the present invention includes a device box 100, a production chamber 110 is provided on the device box 100, and a collection plate 130, a support assembly 200, a grinding cylinder 300, a mounting cylinder 400 and a low-temperature refrigeration device 700 are sequentially installed in the production chamber 110, and the output end of the low-temperature refrigeration device 700 is arranged on the grinding cylinder 300 and controls the low-temperature environment inside the grinding cylinder 300 so that the low-temperature environment inside the grinding cylinder 300 meets the requirements of the flour production process. The low-temperature grinding environment of the flour product ensures the grinding quality of the flour product. The milling cylinder 300 is horizontally arranged in the production chamber 110. The mounting cylinders 400 are fixed at both ends of the milling cylinder 300. The mounting cylinders 400 are connected to the support assembly 200. The collecting tray 130 is located directly below the milling cylinder 300. A control box 120 is installed on one side of the device box 100. The control box 120 is provided with a rotating assembly 600. One end of the rotating assembly 600 extends into the production chamber 110. The device also includes:

[0041] The control assembly 500 includes a rotating disk 510, a bearing 520, a rotating shaft 530, an adjustment disk 540, and a control unit 550. The rotating disk 510 is located in the mounting barrel 400. A rotating shaft 530 is fixed to one side of the rotating disk 510. The rotating shaft 530 is rotatably connected to the inner wall of the mounting barrel 400 via the bearing 520. An adjustment disk 540 is fixed to the other side of the rotating disk 510. The control unit 550 is mounted on the adjustment disk 540. The rotating shaft 530 in the mounting barrel 400 near the side of the rotating assembly 600 is connected to the rotating assembly 600.

[0042] The grinding assembly 800 is horizontally arranged in the grinding cylinder 300, and the two ends of the grinding assembly 800 are rotatably mounted on two control units 550 respectively. The grinding parts 830 and scrapers 860 are evenly distributed on the grinding assembly 800, and the scrapers 860 are located on the outside of the grinding parts 830.

[0043] In the initial state, the axis of the grinding member 830 is eccentric to the axis of the grinding cylinder 300, the scraper 860 does not interfere with the inner wall of the grinding cylinder 300, the rotating assembly 600 drives the rotating disk 510 to rotate via the rotating shaft 530, the rotating disk 510 drives the adjusting disk 540 to rotate, the adjusting disk 540 drives the grinding assembly 800 to rotate eccentrically in the grinding cylinder 300, and the grinding assembly 800 drives the grinding member 830 to rotate eccentrically. The eccentrically rotating grinding member 830 can continuously apply extrusion and grinding forces to the flour product in the grinding cylinder 300, so that the flour particles are gradually crushed and refined, thereby achieving ultra-fine grinding of the flour product and gradually grinding its particle size to meet the required specifications;

[0044] Due to the eccentric rotation of the grinding element 830, the grinding area between it and the grinding cylinder 300 is relatively limited. The control unit 550 can drive the grinding element 830 and the scraper 860 to move radially in the grinding cylinder 300 by rotating, thereby changing the eccentric distance between the grinding element 830 and the grinding cylinder 300. This not only facilitates flour products of different specifications to better enter the grinding area between the grinding element 830 and the grinding cylinder 300, but also ensures that the flour products in the grinding cylinder 300 can be better and faster. The flour products adhered to the inner wall of the grinding cylinder 300 can be scraped off by the scraper 860 so that they can fall into the grinding area, thereby facilitating the cooperation between the grinding element 830 and the grinding cylinder 300 to complete the ultrafine grinding of the flour products, avoiding excessive adhesion of flour products and affecting the grinding efficiency and grinding quality of the device, and greatly improving the adaptability and flexibility of the device.

[0045] In a preferred embodiment, the rotating disk 510, the rotating shaft 530, the mounting cylinder 400, the grinding cylinder 300 and the adjusting disk 540 are all concentric;

[0046] The grinding cylinder 300 is provided with a square channel 310 that is interconnected on one side, and a storage barrel 320 is installed on one side of the square channel 310. When the grinding cylinder 300 is discharging, the square channel 310 is separated from the storage barrel 320 and rotated to the top of the collecting plate 130, so that the flour products in the grinding cylinder 300 can fall onto the collecting plate 130 through the square channel 310, completing the collection of the flour products; the storage barrel 320 can be filled with flour products required for grinding in the next stage in advance. When the square channel 310 completes the discharge of the flour products in the previous stage, the grinding cylinder 300 is rotated again so that the discharge port of the square channel 310 faces upward. At this time, the storage barrel 320 is fixed on the square channel 310, so that the flour products in the storage barrel 320 can fall into the grinding cylinder 300 through the square channel 310, facilitating ultrafine grinding thereof by the grinding assembly 800.

[0047] like Figures 2 to 5As shown, as a preferred embodiment of the present invention, the control unit 550 includes a slider 551, a side bracket 552, a screw 553, a mounting plate 554 and a motor 555. The slider 551 is slidably installed in the adjustment slot 541 opened on the adjustment disk 540. The slider 551 is rotatably connected to the grinding assembly 800. A side bracket 552 is vertically fixed to one side of the slider 551. The side bracket 552 is threadedly connected to the screw 553 installed on the mounting plate 554. The mounting plate 554 is fixed to one side of the adjustment disk 540. A motor 555 is fixed on the mounting plate 554. The output end of the motor 555 is connected to one end of the screw 553.

[0048] Motor 1 555 drives the screw 553 to rotate. The screw 553 can drive the slider 551 to slide in the adjustment groove 541 by rotating and being screwed to the side bracket 552. The slider 551 can drive the grinding assembly 800 to move radially, thereby changing the eccentric distance between the grinding assembly 800 and the grinding cylinder 300, so that the grinding assembly 800 can quickly and efficiently perform ultra-fine grinding on the flour products in the grinding cylinder 300, and gradually grind the particle size to the required specifications, thereby improving the grinding quality and grinding efficiency of the device for flour products.

[0049] In a preferred embodiment, the adjustment groove 541 is opened on the adjustment disk 540 along the radial direction of the adjustment disk 540, and the slider 551 slides in the adjustment groove 541, so that the grinding assembly 800 can be moved to a position concentric or eccentric with the adjustment disk 540, thereby meeting the grinding requirements of flour products.

[0050] like Figures 2 to 9 As shown in FIG. 8 , as a preferred embodiment of the present invention, the grinding assembly 800 includes a grinding shaft 810, a grinding roller 820, a mounting post 850, and a spring 880. The grinding shaft 810 is arranged parallel to the grinding cylinder 300. The two ends of the grinding shaft 810 are rotatably connected to the sliders 551 on the two adjustment disks 540. The grinding roller 820 is fixed to the grinding shaft 810. The outer wall of the grinding roller 820 is equidistantly distributed with grinding pieces 830. One side of the grinding piece 830 is connected to the grinding roller 820. The grinding grooves 330 are evenly distributed on the inner wall of the grinding cylinder 300, and a notch 840 is provided on the other side of the grinding piece 830. The mounting column 850 is vertically slidably set in the notch 840. One end of the mounting column 850 extends to the mounting hole 870 opened on the grinding roller 820. One end of the mounting column 850 is connected to the spring 880 installed in the mounting hole 870. The other end of the mounting column 850 extends to the outside of the grinding piece 830 and is fixedly connected to the scraper 860.

[0051] The adjusting disk 540 drives the grinding shaft 810 and the grinding roller 820 to rotate eccentrically within the grinding cylinder 300 via the slider 551. The grinding roller 820 drives the multiple grinding elements 830 and the scraper 860 to rotate eccentrically. The eccentrically rotating grinding elements 830 can continuously apply extrusion and grinding forces to the flour product within the grinding cylinder 300, gradually crushing and refining the flour particles, thereby achieving ultra-fine grinding of the flour product.

[0052] When the slider 551 drives the grinding shaft 810 and the grinding roller 820 to move radially, the grinding roller 820 drives the multiple grinding parts 830 and the scraper 860 to move radially, thereby changing the eccentric distance between the grinding parts 830 and the grinding cylinder 300. This not only facilitates flour products of different specifications to better enter the grinding area between the grinding parts 830 and the grinding cylinder 300, ensuring that the flour products in the grinding cylinder 300 can be better and faster ground, reducing the grinding time, and improving the grinding efficiency and grinding quality of the device, but also facilitates the scraper 860 to move to a position that conflicts with the inner wall of the grinding cylinder 300, so that the scraper 860 can scrape off the flour products adhered to the inner wall of the grinding cylinder 300, so that they can fall into the grinding area, thereby facilitating the cooperation between the grinding parts 830 and the grinding cylinder 300 to complete the ultrafine grinding of the flour products.

[0053] In a preferred embodiment, the grinding element 830 preferably adopts a circular block structure, and the scraper 860 preferably adopts an arc-shaped plate structure;

[0054] In the initial state, the slider 551 is located on one side of the adjustment groove 541. At this time, the grinding shaft 810 is eccentric to the adjustment disk 540, so that one side of the grinding member 830 can penetrate into the grinding groove 330, thereby completing the ultra-fine grinding of the flour product; when the slider 551 moves toward the direction close to the axis of the adjustment disk 540, the slider 551 drives the grinding shaft 810 to move radially, thereby changing the axial position of the grinding shaft 810 and the adjustment disk 540, and the grinding shaft 810 drives the grinding member 830 to move radially, thereby increasing the distance between it and the grinding groove 330, so that the flour product can better enter the grinding area. At the same time, it can facilitate the scraper 860 to move to the position where it conflicts with the inner wall of the grinding cylinder 300, and scrape off the flour product attached to the inner wall of the grinding cylinder 300, thereby ensuring the grinding efficiency and grinding quality of the device.

[0055] like Figures 1 to 3As shown, as a preferred embodiment of the present invention, the support assembly 200 includes a hydraulic component 210, a connecting frame 220, a bottom bracket 230 and a top bracket 240. The hydraulic component 210 is symmetrically arranged in the production chamber 110. The output end of the hydraulic component 210 is rotatably connected to the connecting frame 220 fixed to the bottom of the bottom bracket 230. A top bracket 240 is installed above the bottom bracket 230. The mounting cylinder 400 is located between the bottom bracket 230 and the top bracket 240 and is rotatably connected to both of them.

[0056] In the initial state, the extension and contraction lengths of the two hydraulic components 210 are the same, so that the top bracket 240, the bottom bracket 230 and the mounting cylinder 400 on the two hydraulic components 210 are all in a horizontal state. The grinding assembly 800 can ultra-finely grind the flour product in the grinding cylinder 300 by eccentric rotation;

[0057] When the grinding assembly 800 grinds the flour product, the extension and contraction lengths of the two hydraulic components 210 are reciprocated, so that the horizontal heights of the output ends of the two hydraulic components 210 are different, thereby reciprocating the horizontal heights of the two mounting cylinders 400, causing the grinding cylinder 300 and the grinding assembly 800 to continuously tilt. This facilitates the axial reciprocating movement of the flour product in the grinding cylinder 300, and facilitates the rotating grinding assembly 800 to quickly and efficiently perform ultrafine grinding on the flour product, thereby reducing the grinding time of the flour product.

[0058] When the grinding assembly 800 completes the grinding of the flour product, the scraper 860 in the grinding assembly 800 moves to a position where it conflicts with the inner wall of the grinding groove 330, so that the flour product hidden in the grinding groove 330 can be discharged. The support assembly 200 reciprocates to change the telescopic length of the two hydraulic parts 210, so that the grinding cylinder 300 and the grinding assembly 800 tilt back and forth again. The scraper 860 in the rotating state cooperates with the support assembly 200, so that the flour product in the grinding cylinder 300 can be quickly discharged from the square channel 310 on the grinding cylinder 300, thereby reducing the discharge time of the flour product and improving the working efficiency, flexibility and practicality of the device.

[0059] In a preferred embodiment, the hydraulic component 210 preferably adopts a hydraulic telescopic structure composed of a hydraulic cylinder and a hydraulic rod;

[0060] The bottom bracket 230 and the top bracket 240 are connected as a whole by bolts.

[0061] like Figure 2 、 Figure 3 and Figure 10As shown, as a preferred embodiment of the present invention, the rotating assembly 600 includes a second motor 610, a main shaft 620 and a linkage unit 630. The second motor 610 is fixed in the control box 120. The main shaft 620 is fixed on the output end of the second motor 610. One end of the main shaft 620 extends into the production chamber and is connected to a rotating shaft 530 in a mounting cylinder 400 through the linkage unit 630.

[0062] like Figure 2 、 Figure 3 and Figure 10 As shown, as a preferred embodiment of the present invention, the linkage unit 630 includes a linkage disk 1 631, a universal joint 632, a fixed sleeve 633, a sliding column 634 and a linkage disk 2 635, the linkage disk 1 631 is concentrically fixed on the main shaft 620, the universal joint 632 is fixed on one side of the linkage disk 1 631, the linkage disk 2 635 is concentrically fixed on the rotating shaft 530, the universal joint 632 is fixed on one side of the linkage disk 2 635, a fixed sleeve 633 and a sliding column 634 are installed between the two universal joints 632, and the sliding column 634 is axially slidably connected to the fixed sleeve 633.

[0063] In a preferred embodiment, the second motor 610 drives the main shaft 620 to rotate, and the main shaft 620 drives the linkage disk 1 631 and the universal joint 632 thereon to rotate. The universal joint 632 on the linkage disk 1 631 can drive the linkage disk 2 635 to rotate through the fixed sleeve 633 and the sliding column 634. The linkage disk 2 635 drives the rotating shaft 530 to rotate, thereby driving the grinding assembly 800 to rotate eccentrically or concentrically within the grinding cylinder 300. The grinding assembly 800 can not only complete the ultra-fine grinding of flour products, but also quickly scrape off flour products adhered to the inner wall of the grinding cylinder 300, thereby reducing the grinding time and discharge time of the device and improving the working efficiency, flexibility and practicality of the device.

[0064] The two universal joints 632 and the sliding connection of the fixed sleeve 633 and the sliding column 634 can ignore the inclination angle of the grinding cylinder 300 and the rotating shaft 530, so that the motor 2 610 can efficiently and quickly transmit the rotation speed to the rotating shaft 530, ensuring the working stability of the grinding assembly 800.

[0065] A method for using the low-temperature ultrafine grinding device for flour products as described above comprises the following specific steps:

[0066] 1. Motor 1 555 drives the screw 553 to rotate. The screw 553 rotates and is screwed to the side bracket 552, thereby driving the slider 551 to slide in the adjustment slot 541. The slider 551 can drive the grinding assembly 800 to move radially, thereby changing the axial position of the grinding assembly 800. In the initial state, the axis of the grinding member 830 is eccentric to the axis of the grinding cylinder 300, the scraper 860 does not interfere with the inner wall of the grinding cylinder 300, and the extension lengths of the two hydraulic components 210 are consistent, so that the top bracket 240, the bottom bracket 230 and the mounting cylinder 400 on the two hydraulic components 210 are all in a horizontal state.

[0067] The second motor 610 drives the main shaft 620 to rotate. The main shaft 620 drives the linkage disk 1 631 and the universal joint 632 thereon to rotate. The universal joint 632 on the linkage disk 1 631 can drive the linkage disk 2 635 to rotate via the fixed sleeve 633 and the sliding column 634. The linkage disk 2 635 drives the rotating shaft 530 to rotate. The rotating disk 510 drives the adjustment disk 540 to rotate. The adjustment disk 540 drives the grinding shaft 810 and the grinding roller 820 to rotate eccentrically within the grinding cylinder 300 via the slider 551. The grinding roller 820 drives the multiple grinding elements 830 and the scraper 860 to rotate eccentrically. The eccentrically rotating grinding elements 830 can continuously apply extrusion and grinding forces to the flour product in the grinding cylinder 300, so that the flour particles are gradually crushed and refined, thereby achieving ultra-fine grinding of the flour product.

[0068] Second, due to the eccentric rotation of the grinding element 830, the grinding area between it and the grinding cylinder 300 is relatively limited. When the slider 551 drives the grinding shaft 810 and the grinding roller 820 to move radially, the grinding roller 820 drives the multiple grinding elements 830 and the scraper 860 to move radially, thereby changing the eccentric distance between the grinding element 830 and the grinding cylinder 300. This not only facilitates the better entry of flour products of different specifications into the grinding area between the grinding element 830 and the grinding cylinder 300, ensuring that the flour products in the grinding cylinder 300 can be better and faster ground, reducing the grinding time and improving the grinding efficiency and grinding quality of the device, but also facilitates the movement of the scraper 860 to a position that conflicts with the inner wall of the grinding cylinder 300, so that the scraper 860 can scrape off the flour products adhering to the inner wall of the grinding cylinder 300 and allow them to fall into the grinding area;

[0069] The reciprocating length of the two hydraulic components 210 is changed, so that the horizontal heights of the output ends of the two hydraulic components 210 are different, thereby reciprocating the horizontal heights of the two mounting cylinders 400, causing the grinding cylinder 300 and the grinding assembly 800 to continuously tilt. This facilitates the axial reciprocating movement of the flour product in the grinding cylinder 300, and facilitates the rotating grinding assembly 800 to quickly and efficiently perform ultrafine grinding on the flour product, thereby reducing the grinding time of the flour product.

[0070] 3. When the flour products in the milling cylinder 300 need to be discharged, the control unit 550 can drive the scraper 860 to move to a position that conflicts with the inner wall of the milling groove 330 by rotating, and at the same time cooperate with the rotating component 600 to discharge the flour products hidden in the milling groove 330. The support component 200 again changes the telescopic length of the two hydraulic parts 210 back and forth, so that the milling cylinder 300 and the milling component 800 tilt back and forth again. The scraper 860 in the rotating state cooperates with the support component 200, so that the flour products in the milling cylinder 300 can be quickly discharged from the square channel 310 on the milling cylinder 300, thereby completing the efficient discharge of flour products and reducing the discharge time of flour products.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
