DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] A typical embodiment of the present invention provides a method for preparing premixed porridge, comprising the following steps:

[0037] Step 1: Clean the raw materials: rice, beans, wheat or fruits;

[0038] Step 2: Ripening: Ripening the raw materials and freeze-drying them after aging;

[0039] Step 3, crushing: pour the freeze-dried porridge grains into the feed roller 1 of the crushing device, and crush them using the rotary screen of the crushing device in conjunction with the roller 2 to obtain porridge powder;

[0040] Step 4: Add other powder ingredients for porridge into the porridge powder according to the proportion and mix well;

[0041] Step 5: Packaging: Pack the mixture of porridge powder and classified auxiliary materials.

[0042] like Figures 1 to 8 As shown, another typical embodiment of the present invention provides a premixed porridge crushing device, including a box body 26, wherein a feed roller 1 and a grinding roller 2 are rotatably installed on both sides of the box body 26, a rotary screen mesh is meshed and connected between the feed roller 1 and the grinding roller 2, the rotary screen mesh includes a plurality of mesh pieces 3, and connecting columns 4 are arranged at both the front and rear ends of the mesh pieces 3, and two adjacent mesh pieces 3 are rotatably connected by the connecting columns 4, and a feed groove 5 and a grinding groove adapted to the mesh pieces 3 are equidistantly arranged on the circumferential surface of the feed roller 1 and the circumferential surface of the grinding roller 2. 6, a grinding plate 7 is arranged in the grinding groove 6, and a support plate 8 is arranged on the outer side of the mesh 3. Both sides of the front end of the support plate 8 are rotatably connected to the connecting column 4 located on the front side of the mesh 3 through supporting ears. The support plate 8 corresponding to the lateral part of the lower side of the rotary screen is supported by the inner bottom wall of the box body 26 in a state of close contact with the outer surface of the mesh 3 before passing through the grinding groove 6 at the bottom of the grinding roller 2. A discharge hole 9 is opened on the front side of the inner bottom wall of the box body 26, and the support plate 8 moves to the top of the discharge hole 9 and separates from the mesh 3 after passing over the grinding groove 6 at the bottom of the grinding roller 2.

[0043] In this embodiment, during the rotation of the feed roller 1, the porridge grains inside it fall from the feed hole 11 into each mesh sheet 3. When the mesh sheet 3 carrying the porridge grains passes through the bottom of the roller 2, it is crushed and broken by the rolling plate 7 located in the rolling groove 6 at the bottom of the roller 2. During the crushing and breaking process, the support plate 8 supports the mesh sheet 3 from the bottom to prevent the mesh sheet 3 from being squeezed and deformed. After the crushing is completed, the mesh sheet 3 moves to the top of the discharge hole 9. At this time, the support plate 8 is separated from the mesh sheet 3, and the crushed porridge grains on the mesh sheet 3 fall into the discharge hole 9 to achieve discharge.

[0044] By applying the crushing device in the above embodiment, the particles of premixed porridge are manufactured. Since the feed slot 5 of the feed roller 1 corresponds to each mesh 3 one by one, the feed hole 11 corresponds to each mesh 3 one by one, so that the feed amount on each mesh 3 is relatively uniform, and the screening area of ​​each mesh 3 can be fully utilized to improve the crushing effect and the screening effect. In addition, during the crushing process, the support plate 8 supports the rolling plate 7, which can effectively prevent the mesh 3 from deforming and increase its service life. In addition, when the mesh 3 moves to the upper side and is distributed horizontally, the porridge particles remaining on its inner surface will fall onto the mesh 3 located below, thereby achieving repeated crushing of the porridge particles and improving the crushing efficiency and the crushing effect.

[0045] The feed roller 1 and the grinding roller 2 are hollow columnar structures with the same outer diameter, the mesh 3 is an arc-shaped structure with the feed roller 1 being circular and arched outward, and the inner side surface of the support plate 8 is provided with an arc surface adapted to the outer side surface of the mesh 3. By configuring the mesh 3 in this way, the locking effect of the mesh 3 can be improved, and the lateral displacement of the porridge grains can be reduced during the grinding process, further ensuring the crushing effect thereof, and at the same time, the conveying effect of the mesh 3 on the porridge grains can be improved.

[0046] Engaging grooves 10 for engaging the connecting column 4 are provided on both sides of the notches of the feed trough 5 and the grinding trough 6. A strip-shaped feeding hole 11 connected to the inner cavity of the feed roller 1 is opened on the inner wall of the feed trough 5. A spiral blade 12 opposite to the rotation direction of the feed roller 1 is provided inside the feed roller 1. Feed pipes 13 are provided at both ends of the feed roller 1. The spiral blade 12 is arranged into two spiral parts with opposite spiral directions and symmetrical distribution, and one end of the rotating shaft of the spiral blade 12 extends from the box body 26 and is connected to the feed motor 14. One end of the grinding roller 2 is connected to the first power motor 15 for driving the grinding roller 2 to rotate.

[0047] In this embodiment, the meshing groove 10 and the connecting column 4 are used to bite each other, so that the mesh 3 can always be in a corresponding state with the feeding groove 5 and the grinding groove 6, ensuring the stability of feeding and crushing. By providing the spiral blade 12, the porridge particles in the feeding roller 1 can fall more evenly onto each mesh 3 through the feeding hole 11, achieving a more quantitative feeding effect.

[0048] At the same time, when the first power motor 15 drives the grinding roller 2 to rotate, the grinding roller 2 drives the rotary screen to rotate through the meshing action of the meshing groove 10 and the connecting column 4, and the rotary screen drives the feed roller 1 to rotate, thereby synchronously realizing the corresponding switching of the feed trough 5 and each mesh 3, and the corresponding switching of the grinding trough 6 and each mesh 3.

[0049] On this basis, the rolling plate 7 is installed in the rolling groove 6 in the radial direction of the rolling roller 2. The inner surface of the rolling plate 7 is connected with a sliding arm 16 that penetrates the inner wall of the rolling groove 6 and extends to the inner cavity of the rolling roller 2. The inner cavity of the rolling roller 2 is provided with a rotating arm 17. The inner end of the rotating arm 17 is rotatably installed on the side wall of the box 26 through a rotating shaft, and the rotating shaft is located below the center of the rolling roller 2 in the height direction. An inner top spring 18 is arranged between the sliding arm 16 and the inner surface of the rolling roller 2. The rotating arm 17 rotates through the inner end of the sliding arm 16, so that the sliding arm 16 drives the rolling plate 7 to move back and forth in the rolling groove 6. One end of the rotating shaft passes through the box 26 and is connected to a second power motor 19, and the rotation speed of the rotating shaft is greater than the rotation speed of the rolling roller 2.

[0050] In this embodiment, while the first power motor 15 drives the roller 2 to rotate, the second power motor 19 drives the rotating arm 17 to quickly perform circular motion. When the rotating arm 17 passes through each sliding arm 16 in turn, it will squeeze the sliding arm 16 outward, so that the sliding arm 16 squeezes the rolling plate 7 outward. At this time, the rolling plate 7 located at the bottom of the roller 2 will cooperate with the support plate 8 to support the mesh 3 during the downward displacement, so as to achieve the crushing of the porridge particles.

[0051] Secondly, while the grinding plate 7 is displacing along the axial direction of the grinding roller 2, the grinding roller 2 and the mesh 3 are both rotating. Therefore, the grinding plate 7 located at the bottom of the grinding roller 2 can realize the process of multiple crushing of the porridge particles, namely, radially outward extrusion and crushing from different angles and rolling crushing combined with the rotating motion of the grinding roller 2, which can greatly improve the crushing effect of the porridge particles.

[0052] At the same time, a certain vibration will be generated when the rotating arm 17 just contacts and leaves the sliding arm 16. This vibration can be more conducive to the porridge particles remaining on the upper mesh 3 falling onto the lower mesh 3 that is about to be crushed, so as to further play the advantage of the upper and lower meshes 3 in the rotary screen being supported in a relative state and improve the circulation crushing effect of the porridge particles.

[0053] On this basis, the outer side of the rolling plate 7 is configured to match the shape of the inner surface of the mesh 3, and the four side surfaces of the rolling plate 7 are fitted with the four inner surfaces of the rolling groove 6. By such a configuration, the rolling plate 7 moves like a piston in the rolling groove 6. When the rolling plate 7 moves outward, the porridge grains are squeezed outward by air pressure. When the rolling plate 7 moves inward, it has a suction effect on the porridge grains. At this time, corresponding to the mesh 3 being rolled, the porridge grains on its inner surface can move upward under the suction effect, and the airflow is used to drive the movement of the porridge grains and loosen the porridge grains, thereby improving the effect of the next rolling, and then improving the crushing effect of the porridge grains.

[0054] The width of the mesh 3 is greater than the width of the milling groove 6. When the mesh 3 is located below the milling groove 6 at the bottom of the milling roller 2, the mesh 3 is exposed at the front and rear sides of the milling groove 6. With this arrangement, when the milling plate 7 moves inward, the airflow from the outside can enter the milling groove 6 through the two sides of the mesh 3. The airflow can gather the porridge grains on the mesh 3 to the middle to further improve the crushing effect. At the same time, it can ensure that the part of the mesh corresponding to the width of the milling plate 7 is supported by the support plate 8, so as to protect the mesh 3 more comprehensively.

[0055] On this basis, the slide arm 16 is a telescopic structure, the inner cavity of the roller 2 is provided with a guide rail 20 fixed to the side wall of the box body 26, and the outer end of the slide arm 16 is provided with a guide wheel 21. The wheel axle of the guide wheel 21 extends into the guide rail 20 and slides with the guide rail 20. When the bottom end of the slide arm 16 passes through the bottom of the guide rail 20, the slide arm 16 is in its longest state, and when the bottom end of the slide arm 16 passes through the rest of the guide rail 20, the slide arm 16 is in its shortest state.

[0056] Specifically, in the process of the grinding groove 6 moving from the rear side of the grinding roller 2 through its bottom to the front side, the outward displacement stroke of the grinding plate 7 in the grinding groove 6 switches from a continuously increasing state to a continuously decreasing state, and when the grinding groove 6 is located at the bottom of the grinding roller 2, the grinding plate 7 is in a state of vertically grinding the porridge grains downward. At this time, the grinding plate 7 moves the farthest downward distance and has the greatest grinding force.

[0057] In this way, when the rolling groove 6 moves from the rear side of the rolling roller 2 to the bottom, the rolling plate 7 gradually increases the rolling pressure on the porridge grains, thereby realizing the gradual rolling of the porridge grains and further improving the rolling effect. In particular, in this process, the piston movement of the rolling plate 7 in the rolling groove 6, after each rolling, the suction effect generated when the rolling plate 7 moves inward will cause the movement of the porridge grains on the mesh 3, which can greatly improve the rolling effect of the porridge grains on the mesh 3.

[0058] When the grinding groove 6 moves from the bottom of the grinding roller 2 to the top of the discharge hole 9, the outward movement stroke of the grinding plate 7 becomes smaller and smaller. At this time, the grinding plate 7 utilizes its piston movement in the grinding groove 6 and the squeezing effect of the airflow during its outward displacement, so that the porridge particles on the mesh 3 have a better discharge effect.

[0059] One end of the roller 2 is open, the guide rail 20 is arranged at the open end of the slide arm 16 facing the roller 2, and the open end of the guide rail 20 facing the roller 2 is installed on the inner wall of the box 26 through the support rod 22, and the output shaft of the second power motor 19 is connected to the closed end of the roller 2.

[0060] A roller 23 for rolling on the inner bottom wall of the box 26 is rotatably mounted on the outer surface of the support plate 8, and the roller 23 on the support plate 8 located in the fourth quadrant of the circumference of the feed roller 1 rolls on the side wall of the box 26. End plates 24 are provided at both ends of the feed roller 1, and a swivel 25 is embedded in the end plate 24. The swivel 25 rotatably cooperates with the end plate 24, and the feed pipe 13 is installed on the swivel 25.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
