Description

Technical Field

[0001] This utility model relates to the field of rice cooling technology, and in particular to a flipping and smoothing device for uniformly cooling steamed rice. Background Technology

[0002] In the brewing industry, cooling the steamed rice, the main fermentation ingredient, is a crucial step. For example, in the production of fermented beverages such as sake and rice wine, the cooked rice needs to be rapidly and evenly cooled to a suitable temperature to facilitate the subsequent mixing with koji (fermentation starter) and yeast, and to smoothly initiate the saccharification and fermentation processes. Precise temperature control is essential for protecting the activity of koji and yeast, ensuring the normal functioning of enzymes, and preventing contamination by other microorganisms. Efficient and uniform cooling not only ensures the stability of the fermentation process, thus affecting the flavor, aroma, and quality of the final product, but also improves production efficiency, meeting the demands of modern brewing processes for automation and precise control.

[0003] Application number CN202420768260.2 discloses a rice cooling device, including a conveyor frame. A transmission shaft is rotatably connected to the inner wall of the conveyor frame, and a heat dissipation mesh belt is drivenly connected to the outer surface of the transmission shaft. A bellows is fixedly connected to the bottom of the conveyor frame, with air inlets on both sides of the bellows. A first fan is fixedly connected inside the bellows. This application features a more concentrated airflow from the diverter nozzle, facilitating penetration of the heat dissipation mesh belt and contact with the rice. Since there are typically gaps between the rice grains, the airflow passes through to dissipate heat. The bellows are relatively long, allowing for effective cooling as the rice passes through. With continuous conveying, the rice falls into the heat dissipation box for collection. A second fan is activated as the rice falls, blowing air through its outlet to further cool the falling rice, ensuring effective cooling and providing a faster cooling speed.

[0004] However, existing technologies still have problems: the common method of spreading rice flat on a mesh belt for air cooling in current rice cooling technologies still has many issues that need to be addressed. Because the rice piles up on the mesh belt without effective turning and stratification, heat dissipation is uneven during the cooling process. Specifically, there is a large temperature difference between the upper and lower layers of rice, and areas near the mesh belt or with thicker piles do not dissipate heat sufficiently, easily leading to localized overheating or insufficient cooling, thus affecting the overall cooling effect of the rice.

[0007] As a preferred technical solution of this utility model, the roller conveying mechanism is used to convey a box containing steamed rice to a predetermined position and pour it into the conveying cavity. It includes a first roller section and a second roller section connected to each other. The first roller section and the second roller section share an outer frame located on the same side. On the side opposite to the outer frame, the first roller section is provided with a first inner frame, and the second roller section is provided with a second inner frame extending laterally relative to the first roller section, so that the second roller section forms an outward expansion relative to the first roller section on its inner side.

[0008] As a preferred technical solution of this utility model, the side-tilting mechanism includes: a connecting frame, which is sandwiched between adjacent rollers and has a notched disc that is rotatably connected at its end; the notched disc has an L-shaped notch for abutting against the outside of the box body, and its side is fixed to the telescopic end of the cylinder to achieve reciprocating rotation.

[0009] As a preferred technical solution of this utility model, the side-tilting mechanism is further provided with a baffle.

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This utility model relates to a flipping and leveling device for uniformly cooling steamed rice. Please refer to [link to relevant documentation]. Figures 1 to 6 As shown, this application includes a conveying chamber 1, a mesh belt conveying mechanism 2 and a fan 11 system, a roller conveying mechanism 12 and a side-tipping mechanism for front-end material feeding, and a chain conveying mechanism 22 for rear-end empty box recycling.

[0021] Furthermore, the roller conveyor mechanism 12, as the initial transport structure, is responsible for transporting the box containing the rice to be cooled to the predetermined position. Specifically, the roller conveyor mechanism 12 consists of a first roller section 13 and a second roller section 14 connected to each other. The two roller sections share an outer frame 15 located on the same side. On the side opposite to the outer frame 15, the first roller section 13 is provided with a first inner frame 16, while the second roller section 14 is provided with a second inner frame 17 that extends laterally relative to the first roller section 13. This results in the second roller section 14 forming an outward expansion relative to the first roller section 13 on its inner side. The outward expansion provides space for the box to tilt, preventing the box from interfering with the equipment structure during the tilting process.

[0022] Furthermore, a side-tilting mechanism is provided at one end of the second roller section 14 near the first roller section 13. The purpose of the side-tilting mechanism is to automatically tilt the box. Specifically, the side-tilting mechanism includes a connecting frame 18 clamped between adjacent rollers. The end of the connecting frame 18 is provided with a notched disc 19 that is rotatably connected. The notch of the notched disc 19 is L-shaped and can abut against and lock the outside of the box. Its side is fixed to the telescopic end of a cylinder and can reciprocate under the drive of the cylinder. In order to enhance the material guiding ability and prevent the steamed rice from scattering during the tilting process, an extension plate 25 is provided at the notch of the notched disc 19 along the direction of its two side notches. The extension plate 25 forms a longer abutment structure to ensure that the steamed rice can be effectively guided. At the same time, the side-tilting mechanism is also provided with a baffle 20. The baffle 20 is provided on the side of the notched disc 19 away from the first roller section 13 and is used to abut against the front end of the box to achieve the positioning of the box. One end of the baffle 20 is fixed to the outer frame 15, and the other end extends along the length of the roller to ensure the stability of the structure and the accuracy of the positioning.

[0023] Furthermore, the conveying chamber 1, as a transitional structure for receiving poured steamed rice, has its input end located above the second inner frame 17, ensuring that the steamed rice poured from the box can fall accurately into it. The conveying chamber 1 is equipped with a stirring roller to initially stir and disperse the freshly poured steamed rice, preventing it from clumping and clogging. The bottom surface of the conveying chamber 1 is a guide surface inclined towards the output end, using gravity to guide the steamed rice smoothly to the downward-facing mesh belt conveyor 2. The input end of the conveying chamber 1 has horizontally extending edges on both sides, forming a funnel-shaped expansion area, thus increasing the rice receiving range. Specifically, the contact surface of the baffle 20 is aligned horizontally with the outer edge of the input end of the conveying chamber 1. This spatial alignment ensures that after the box abuts against the baffle 20 and tilts to the side, the steamed rice to be cooled inside the box can accurately fall into the input end of the conveying chamber 1, reducing material spillage.

[0024] Furthermore, the mesh belt conveyor 2 is located below the output end of the conveying chamber 1 and is a structure for achieving uniform cooling and leveling of steamed rice. Specifically, several support seats 3 are equidistantly mounted above the mesh belt surface of the mesh belt conveyor 2, and the two ends of the support seats 3 are fixed to both sides of the conveying frame 4 to form a support frame. Along the conveying path of the mesh belt conveyor 2, the support base 3 is alternately equipped with rake frames 5 and plow frames 6. The rake frame 5 is horizontally telescopically mounted on the support base 3 via an electric push rod 7. The rake head fixed to the lower part of the rake frame 5 includes a horizontally arranged front end plate 8 and a rear end rake nail. The plate 8 is used to initially smooth the steamed rice, while the rake nail can penetrate deep into the steamed rice, effectively breaking up clumps, loosening the material layer, and promoting heat dissipation. The plow frame 6 is snapped onto the support base 3, and its front end is arrayed with several plow heads 10. The plow heads 10 deeply turn and spread the steamed rice, further eliminating uneven temperature. Several fans 11 are placed above the mesh belt and sandwiched between the rake frame 5 and the plow frame 6, so that the cooling airflow can directly act on the surface of the turned and smoothed steamed rice, significantly improving the cooling efficiency.

[0025] Furthermore, a chain conveyor 22 is provided at the tail end of the roller conveyor mechanism 12. This chain conveyor 22 is specifically used for transporting and recycling empty boxes. The tail end of the chain conveyor 22 is connected to a cleaning chamber to realize automatic cleaning and disinfection of empty boxes. The chain conveyor 22 is also provided with a flipping mechanism 23. This flipping mechanism 23 includes a fixed frame 24 that is adapted to be snapped onto the outside of the box. The fixed frame 24 is rotated through the output end of a motor connected to the shaft. It can adjust the posture of the box according to the cleaning needs, such as turning it upside down for drainage or facilitating spray cleaning, to ensure the thorough cleaning of the box.

[0026] The working principle of this application is as follows: The box containing high-temperature steamed rice first enters the second roller section 14 from the first roller section 13 through the roller conveyor mechanism 12. In the outer expansion space of the second roller section 14, the box is conveyed to the position of the side-tilting mechanism. After the front end of the box abuts against the baffle 20 and is positioned, the cylinder drives the notched disc 19 to rotate. The L-shaped notch of the notched disc 19 locks the outside of the box, causing the box to tilt. During the tilting process, the extension plate 25 effectively guides the flow of materials and prevents the steamed rice from scattering. Since the contact surface of the baffle 20 is precisely aligned with the outer edge of the input end of the conveying chamber 1 in the horizontal direction, the tilted steamed rice falls accurately into the conveying chamber 1. The steamed rice is dispersed by the stirring roller in the conveying chamber 1 and flows along the inclined guide surface to the mesh belt conveyor mechanism 2. On the mesh belt, the steamed rice is successively smoothed and dispersed by the rake frame 5 and turned and flattened by the plow frame 6. At the same time, the cooling airflow provided by the fan 11 penetrates the loose rice layer to achieve rapid and uniform cooling. The rake frame 5, adjusted by the extension and retraction of the electric push rod 7, improves the processing effect by repeatedly smoothing and breaking up the steamed rice. Through the alternating action of multiple sets of rake frames 5 and plow frames 6, combined with air cooling, the steamed rice achieves thorough smoothing, turning, breaking up, and uniform cooling during transport, effectively eliminating temperature differences between the upper and lower layers and achieving a cooling effect. Simultaneously, the emptied container continues to move along the roller conveyor mechanism 12 to the chain conveyor mechanism 22, where it enters the cleaning chamber. With the assistance of the flipping mechanism 23, it completes cleaning and disinfection, realizing the recycling of the container. The entire process achieves fully automated operation from rice feeding and uniform cooling to container recycling and cleaning, significantly improving production efficiency and product quality stability.
