Abstract
Description
Technical Field
[0001] This utility model relates to the field of glutinous rice flour processing technology, and in particular to a powder cooling mechanism for glutinous rice flour processing. Background Technology
[0002] Glutinous rice flour is known for its softness, elasticity, and fragrant texture. It can be used to make foods such as glutinous rice balls, yuanxiao (sweet rice dumplings), and ciba (sticky rice cakes) as well as family snacks. In particular, Ningbo glutinous rice balls are famous throughout China for their unique flavor. The process is as follows: glutinous rice → soaking → grinding into powder → sieving → pressing → crushing → drying → packaging → finished product.
[0003] In the current glutinous rice flour production process, the rice flour is usually dried. After drying, the rice flour is at a high temperature, which is not conducive to collecting the rice flour. At the same time, when cooling the rice flour, the piled rice flour is usually cooled by blowing cold air, which makes it difficult for the heat inside the pile of rice flour to be discharged, resulting in poor cooling effect. Utility Model Content
[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the existing glutinous rice flour production process, it is usually heated. The temperature of the glutinous rice flour after heating is high, which is not conducive to the collection of glutinous rice flour. At the same time, when cooling glutinous rice flour, cold air is usually blown to cool the piled glutinous rice flour, which makes it difficult for the heat inside the pile of glutinous rice flour to be discharged, resulting in poor cooling effect of glutinous rice flour. Therefore, a powder cooling mechanism for glutinous rice flour processing is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A powder cooling mechanism for glutinous rice flour processing includes a box and a horizontal plate, the horizontal plate being slidably connected to the inner wall of the box;
[0007] The box is equipped with a paving component, which includes a scraper, a movable plate, a lead screw, and baffles. Two baffles are fixedly connected to the inner wall of the box. The lower end of the movable plate is slidably connected between the two baffles. One end of the scraper is fixedly connected to the movable plate. The movable plate has a groove. A limit block is fixedly connected to the bottom wall of the groove. Multiple semi-circular blocks are fixedly connected to the bottom wall of the horizontal plate. The limit block is slidably connected to the bottom wall of the horizontal plate. The two ends of the lead screw are rotatably connected to the side wall of the box. The movable plate is threadedly connected to the lead screw.
[0008] Preferably, the paving component further includes a rotating shaft and an exhaust chamber. One end of the rotating shaft is rotatably connected to the movable plate. The exhaust chamber is divided into two chambers, each with an exhaust port on one side wall. The exhaust chamber is slidably connected to the scraper.
[0009] Preferably, airbags are fixedly connected to both ends of the movable plate, and the ends of the two airbags away from the movable plate are fixedly connected to the inner wall of the box, and the two airbags are connected to the chamber through air supply pipes.
[0010] Preferably, a rack plate is fixedly connected to the inner wall of the box, and a toothed pattern is formed on the outer surface of one end of the rotating shaft, and the rotating shaft is engaged with the rack plate through the toothed pattern.
[0011] Preferably, each of the two airbags is fixedly connected to an air inlet pipe, and a one-way valve is installed between the air inlet pipe and the air delivery pipe.
[0012] Preferably, a discharge port is provided on the upper wall of the box.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When the moving plate moves horizontally, it can squeeze the airbags. The gas in the airbags flows through the air supply pipe to the chamber on the right side and is discharged through the exhaust port to the horizontal plate. It can cool the glutinous rice flour on the horizontal plate and then flow through the gap between the horizontal plate and the inner wall of the box to the bottom of the box for collection.
[0015] 2. When the shaft rotates, it can drive the exhaust chamber to move horizontally back and forth on the scraper. Therefore, in the process of the exhaust chamber continuously venting air to cool the glutinous rice, it can move horizontally back and forth continuously. First, it can prevent the glutinous rice from sticking to the scraper. The exhaust chamber can scrape off the glutinous rice powder on the scraper. Second, it can have a better cooling effect on the glutinous rice powder on the horizontal plate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0023] Reference Figures 1-4 A powder cooling mechanism for glutinous rice flour processing includes a box body 1 and a horizontal plate 13. The horizontal plate 13 is slidably connected to the inner wall of the box body 1. Only one side of the horizontal plate 13 away from the moving plate 7 is slidably connected to the inner wall of the box body 1, while the other three sides are separated from the inner wall of the box body 1. A discharge port is provided on the upper wall of the box body 1.
[0024] The paving components are installed inside the housing 1. These components include a scraper 4, a movable plate 7, a lead screw 14, and baffles 9. Both baffles 9 are fixedly connected to the inner wall of the housing 1. The lower end of the movable plate 7 is slidably connected between the two baffles 9. One end of the scraper 4 is fixedly connected to the movable plate 7. The scraper 4 does not contact the horizontal plate 13, leaving a gap between them. A groove is formed on the movable plate 7, and a limiting block 15 is fixedly connected to the bottom wall of the groove. Multiple semi-circular blocks 10 are fixedly connected to the bottom wall of the horizontal plate 13. The limiting blocks 15 are slidably connected to the bottom wall of the horizontal plate 13. The lead screw 14 has two ends... The movable plate 7 is rotatably connected to the side wall of the box 1, and is threadedly connected to the lead screw 14. When the movable plate 7 moves, the limiting block 15 will push the horizontal plate 13 to move upward each time it contacts a semi-circular block 10. When the limiting block 15 continues to move away from the semi-circular block 10, the horizontal plate 13 will move downward and reset under its own weight. The paving component also includes a rotating shaft 5 and an exhaust chamber 3. One end of the rotating shaft 5 is rotatably connected to the movable plate 7. The exhaust chamber 3 is divided into two chambers, and an exhaust port is opened on one side wall of each chamber. The exhaust chamber 3 is slidably connected to the scraper 4.
[0025] Airbags 8 are fixedly connected to both ends of the movable plate 7. The ends of the two airbags 8 away from the movable plate 7 are fixedly connected to the inner wall of the box 1. The two airbags 8 are connected to the chambers through air supply pipes 11. Air inlet pipes 6 are fixedly connected to the two airbags 8. One-way valves are installed between the air inlet pipes 6 and the air supply pipes 11 to prevent glutinous rice powder from being sucked into the air supply pipes 11 and the airbags 8. A toothed plate 12 is fixedly connected to the inner wall of the box 1. One end of the rotating shaft 5 has teeth on its outer surface. The rotating shaft 5 is connected to the toothed plate 12 through the teeth.
[0026] In this invention, during use, glutinous rice flour is first poured into the box 1 through the feeding port and placed on the horizontal plate 13. Then, one end of the lead screw 14 is connected to the drive end of an external servo motor, and the lead screw 14 is driven to rotate under the drive of the servo motor. When the lead screw 14 rotates, it can drive the moving plate 7 to move horizontally back and forth between the two baffles 9. When the scraper 4 moves horizontally back and forth with the moving plate 7, it can push the glutinous rice flour accumulated on the horizontal plate 13 to one side of the horizontal plate 13. At the same time, the moving plate 7 moves to the right and pushes... As the glutinous rice flour on the horizontal plate 13 moves to the right, the moving plate 7 squeezes the air bladder 8 located on the right side. At this time, the one-way valve on the air inlet pipe 6 on the air bladder 8 on the right side closes, while the one-way valve on the air delivery pipe 11 opens. The gas in the air bladder 8 on the right side flows through the air delivery pipe 11 to the chamber on the right side and is discharged through the exhaust port to the horizontal plate 13. This can cool the glutinous rice flour on the horizontal plate 13. The cooled glutinous rice flour then flows through the gap between the horizontal plate 13 and the inner wall of the box 1 to the bottom of the box 1 for collection.
[0027] Simultaneously, when the moving plate 7 moves, the semicircular block 10, when restrained by the limiting block 15, can cause the horizontal plate 13 to move upward. As the moving plate 7 moves, the horizontal plate 13 moves up and down repeatedly, which can shake the glutinous rice flour piled on the horizontal plate 13 to a thinner state and spread it on the horizontal plate 13, so that the gas discharged from the exhaust chamber 3 can quickly cool the glutinous rice flour. Similarly, when the moving plate 7 moves to the left, it can squeeze the air bladder 8 located on the left side. At this time, the air bladder 8 on the right side is stretched. When the air bladder 8 on the right side is stretched, the one-way valve on the air inlet pipe 6 opens and the one-way valve on the air delivery pipe 11 closes. The outside gas enters the air bladder 8 located on the right side through the air inlet pipe 6. At the same time, when the air bladder 8 located on the left side is pressurized, the gas inside it is input into the chamber located on the left side through the air delivery pipe 11, which can cool the glutinous rice flour located on the left side of the scraper 4.
[0028] Meanwhile, as the rotating shaft 5 moves horizontally along with the exhaust chamber 3 and the scraper 4, since one end of the rotating shaft 5 is meshed with the rack plate 12, it can rotate when the rotating shaft 5 moves horizontally. When the rotating shaft 5 rotates, it can drive the exhaust chamber 3 to move horizontally back and forth on the scraper 4. Therefore, during the process of the exhaust chamber 3 continuously exhausting air to cool the glutinous rice, it can move horizontally back and forth continuously. This serves two purposes: first, it prevents the glutinous rice from sticking to the scraper 4, and the exhaust chamber 3 can scrape off the glutinous rice powder on the scraper 4; second, it can have a better cooling effect on the glutinous rice powder on the horizontal plate 13.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
