Description

Technical Field

[0001] The utility model relates to the technical field of rice noodle production equipment, and particularly relates to a grinding device for rice noodle production. Background Art

[0002] Rice noodles, a special snack, are very popular foods in southern China. Rice noodles are strip-shaped or filamentous rice products made from rice through processes such as soaking, steaming, and pressing, rather than powdered materials ground from rice as understood in the literal sense. Rice noodles have the characteristics of flexible texture, elasticity, not getting mushy when boiled in water, and not easily breaking when stir-fried.

[0003] When rice noodles are produced and processed, the rice needs to be ground into powder first. In the process of rice noodle production, the rice needs to be ground first. Since the rice often has different particle sizes, the sizes after grinding are also uneven, and the grinding efficiency is not high. Therefore, when the requirements are not met in the first grinding, secondary grinding is usually required. Before secondary grinding, it is also necessary to manually separate the rice noodles that have met the requirements from the rice grains that have not met the requirements. This grinding method not only consumes the energy of the staff but also has low production efficiency, and the rice on the filter screen after grinding is not easy to clean. Therefore, there is still room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a grinding device for rice noodle production to solve the problems mentioned in the above background art.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions: A grinding device for rice noodle production includes a grinding box and a feed hopper arranged on the top of the grinding box. Inside the grinding box, there are a pair of filter racks at the feed hopper. The bottoms of the pair of filter racks are mutually attached to form a V shape. The filter rack includes a filter screen and connecting parts arranged at the mutually remote ends of the filter screen. Inside the grinding box, there are a pair of rotatable first rotating shafts. Each connecting part is circumferentially fixedly connected to the corresponding first rotating shaft. A pair of first motors are installed on the grinding box, and the output ends of the pair of first motors are respectively connected to the pair of first rotating shafts. Inside the grinding box, there are a pair of second rotating shafts below the middle of the pair of filter racks. A pair of mutually cooperating grinding rollers are fixed on the pair of second rotating shafts. A pair of second motors are installed on the grinding box, and the output ends of the pair of second motors are respectively connected to the pair of second rotating shafts. Inside the grinding box, brush net mechanisms are arranged on both sides where the pair of filter racks are mutually remote. The brush net mechanism includes a brush rod, a cylindrical brush fixedly sleeved on the brush rod, and a driving component for driving the displacement of the brush rod.

[0006] With the above technical solution, during milling, the staff first put the rice into the feed hopper. The rice falls from the feed hopper above the filter screen. The filter screen intercepts the large-grained rice, and the small-grained rice falls onto a pair of milling rollers for milling. When the small-grained rice is milled, the first motor drives the first rotating shaft to rotate, thereby driving the connecting part to rotate, causing a pair of filter frames to rotate in a direction away from each other. One end of the pair of filter frames that fits together opens, and the large-grained rice also falls onto a pair of milling rollers for milling, thus realizing the separate milling of large and small grains of rice, eliminating manual separation, reducing the burden on the staff, and improving production efficiency. When the filter screen is adhered with rice and needs to be cleaned, control the first motor to drive the filter frame to rotate towards the brush net mechanism and fit with the cylindrical brush, and then control the displacement of the brush rod through the driving component to rub against the filter screen to clean the surface of the filter screen.

[0007] As a further optimization of the present utility model, a pair of magnetic blocks are provided at one end of the pair of filter frames close to each other, and the pair of magnetic blocks are tightly fitted by magnetism.

[0008] With the above technical solution, by means of magnetic attraction, the pair of filter frames can be more tightly fitted when they are in contact, avoiding the leakage of rice.

[0009] As a further optimization of the present utility model, a pair of fixed frames are provided above the milling box, distributed front and back. The driving component includes a guide rod arranged between the fixed frames, a rotatable screw rod, and a third motor with an output shaft connected to the screw rod. A connecting seat is provided at the top of the brush rod after passing through the top of the milling box upward. The connecting seat is provided with a screw hole adapted to the screw rod and a through hole for the guide rod to pass through.

[0010] With the above technical solution, start the third motor to drive the screw rod to rotate, drive the connecting seat, and the connecting seat moves back and forth along the guide rod under the drive of the screw rod, thereby driving the brush rod to move back and forth, so that the cylindrical brush rubs against the filter screen to clean the surface of the filter screen.

[0011] As a further optimization of the present utility model, a pair of third rotating shafts are provided below a pair of milling rollers inside the milling box, and roller-shaped brushes are sleeved on the third rotating shafts.

[0012] With the above technical solution, when the milling roller is adhered with rice powder and needs to be cleaned, start the second motor to drive the second rotating shaft to rotate, thereby driving the roller-shaped brush to rotate to clean the surface of the milling roller.

[0013] As a further optimization of the present utility model, a receiving frame is provided at the inner bottom of the milling box. An opening for the receiving frame to enter and exit is provided on the side wall of the milling box, and a push-pull handle is provided on the side wall of the receiving frame.

[0014] With the above technical solution, the milled rice flour falls into the material collection frame for collection. The staff can pull the push-pull rod to pull out the material collection frame, thereby taking out the rice flour.

[0015] The beneficial effects of the present utility model are as follows: During milling, the staff first puts the rice into the feed hopper. The rice falls above the filter screen through the feed hopper. The filter screen intercepts the large-grained rice, and the small-grained rice falls onto a pair of milling rollers for milling. When the small-grained rice is milled, the first motor drives the first rotating shaft to rotate, thereby driving the connecting part to rotate, causing a pair of filter frames to rotate in a direction away from each other. One end of the pair of filter frames that fits together opens, and the large-grained rice also falls onto the pair of milling rollers for milling, thus realizing the separate milling of large and small-grained rice sieves, eliminating manual separation, reducing the burden on the staff, and improving production efficiency. When the rice adheres to the filter screen and needs to be cleaned after milling, control the first motor to drive the filter frame to rotate towards the brush net mechanism and fit with the cylindrical brush, and then control the displacement of the brush rod through the driving component to rub against the filter screen to clean the surface of the filter screen.
