Description

[0025] In order to ensure the processing quality of rice and facilitate its handling, the rice needs to be cooled. Conventional cooling methods mainly use natural ventilation or air cooling equipment to dissipate heat. In order to improve the heat dissipation efficiency, the existing method usually requires spreading the rice, which usually requires a large spreading area, and the spreading and collection efficiency is low.

[0026] In view of this, the present application proposes a rice cooling device.

[0027] In the examples of this application, refer to Figures 1 to 4 The above-mentioned rice cooling equipment includes: a cylindrical shell 1, a feed pipe 2, a discharge pipe 3, an air inlet pipe 4, and an air outlet pipe 5. The feed pipe 2 and the air outlet pipe 5 are arranged at the upper end of the shell 1, the discharge pipe 3 and the air inlet pipe 4 are arranged at the lower end of the shell 1, the air inlet pipe 4 is connected to the blowing device, and the blowing device can be a fan (existing technology). The blowing device is used to blow air into the shell 1 through the air inlet pipe 4. A bulk material structure 6 and a shaking material structure 7 are provided in the shell 1. The bulk material structure 6 is used to disperse the rice into the shaking material structure 7, and the shaking material structure 7 is used to make the rice gradually move toward the discharge pipe 3 in a shaking state; the shaking material structure 7 includes a plurality of shaking material trays 710 and a vibrator 720 distributed up and down. The plurality of shaking material trays 710 are each provided with a first drop hole 711 for the rice to pass through, and the vibrator 720 is used to drive the plurality of shaking material trays 710 to vibrate.

[0028] Specifically, when in use, the rice enters the shell 1 from the feed pipe 2, falls into the shaking structure 7 after being dispersed by the bulk structure 6, and gradually moves toward the discharge pipe 3 under the shaking of the shaking plate 710; at the same time, the blowing equipment supplies air into the shell 1 through the air inlet pipe 4, and the cold air is discharged from the air outlet pipe 5 after fully contacting the rice; this design utilizes the vibration and countercurrent air cooling principles to enable the rice to fully exchange heat with the cold air during the movement, thereby achieving cooling and cooling; multiple shaking plates 710 are distributed up and down, so that the rice moves slowly between multiple shaking plates 710, which can effectively increase the contact time between the rice and the cold air, that is, the heat exchange time. This design has a compact structure and does not require too large a spreading area. The input and output of rice are facilitated by the feed pipe 2 and the discharge pipe 3. By dispersing and shaking the rice, each grain of rice can fully contact the cold air for heat exchange, thereby increasing the cooling efficiency and uniformity. When this device is in use, rice can be continuously input and output, further improving the cooling efficiency.

[0029] In this embodiment, a plurality of mounting rods 740 are arranged between the plurality of shaking material trays 710, and the plurality of shaking material trays 710 are fixedly connected to the plurality of mounting rods 740, and the plurality of mounting rods 740 are installed on the inner wall of the shell 1 through the shock-absorbing structure 8; the shaking material trays 710 rigidly connected by the mounting rods 740 can vibrate synchronously, and the shock-absorbing structure 8 buffers the vibration transmission, which can reduce the impact of the vibration on the shell 1 and reduce the equipment noise and wear.

[0030] Specifically, refer to Figure 1 There is a gap between each shaking material plate 710 and the inner wall of the shell 1, which can prevent the vibrating shaking material plate 710 from affecting the shell 1 and reduce equipment noise and wear. A baffle 712 is fixedly installed near the edge of each shaking material plate 710. The baffle 712 can block the material and prevent rice from falling from the gap between the shaking material plate 710 and the shell 1.

[0031] In this embodiment, the bulk structure 6 includes a bulk plate 610, the outer sides of the bulk plate 610 are fixedly connected to multiple mounting rods 740 respectively, and multiple second drop holes 611 are opened on the bulk plate 610. A bulk table 620 is fixedly installed on the bulk plate 610 corresponding to the feed pipe 2, and the side of the bulk table 620 is a conical structure; the rice falls from the feed pipe 2 to the conical side of the bulk table 620, and will be dispersed by the conical surface and fall on the bulk plate 610, and then fall into the shaking plate 710 below through the second drop holes 611 of the bulk plate 610; the centrifugal force of the conical structure is used to evenly disperse the rice, avoid concentrated accumulation, expand the cooling contact area, optimize the initial dispersion effect, and provide evenly distributed materials for subsequent cooling.

[0032] Specifically, refer to Figure 4A ring-shaped buffer strip 650 is provided on the outside of the bulk plate 610. The inner ring of the buffer strip 650 is fixedly connected to the bulk plate 610. The outer ring of the buffer strip 650 is in close contact with the inner wall of the shell 1. The buffer strip 650 is made of elastic material. The cross-section of the buffer strip 650 is a hollow trapezoidal structure. A slope with a low middle and high edge is formed on the buffer strip 650, so that the rice can slide along the slope to the bulk plate 610. The buffer strip 650 can prevent the rice from falling from the gap between the bulk plate 610 and the shell 1, and can also prevent the vibration of the bulk plate 610 from affecting the shell 1.

[0033] In this embodiment, a vibrator 720 is fixedly installed inside the bulk material table 620, and a vibration transmission rod 730 is passed through and fixed between the bulk material plate 610 and the multiple shaking material trays 710, and the vibration transmission rod 730 is connected to the vibrator 720; the vibrator 720 is installed inside the bulk material table 620, and the vibration is transmitted to the bulk material plate 610 and the shaking material tray 710 through the vibration transmission rod 730, realizing overall synchronous vibration, and the single-point driven vibration transmission mechanism ensures that the vibration frequency of each component is consistent, thereby enhancing the fluidity of the material; the vibrating bulk material table 620 and bulk material plate 610 are also conducive to the dispersion of rice.

[0034] In this embodiment, a bulk block 630 with a hemispherical shell structure is provided on the top surface of the bulk platform 620, and the convex curved surface of the bulk block 630 faces the feed pipe 2. The bulk block 630 is fixedly mounted on the bulk platform 620 by a first spring 640; when the rice impacts the hemispherical curved surface of the bulk block 630, the bulk block 630 is buffered and rebounded by the first spring 640, further dispersing the rice. In conjunction with the use of the vibrator, the bulk block 630 is continuously shaken by the first spring 640, further enhancing the rebound of the rice; the combination of elastic collision and curved surface diversion causes the rice to be scattered in multiple directions, avoiding vertical falling to form accumulation, enhancing the initial dispersion effect, reducing agglomeration, and improving cooling efficiency.

[0035] Specifically, an elastic pad 631 is installed on the convex curved surface of the bulk block 630; the elastic pad 631 on the surface of the bulk block 630 cushions the impact of rice, reduces the breakage rate, and assists in dispersing the material. The elastic pad 631 absorbs impact energy and reduces the risk of rice grain breakage. While ensuring the dispersion effect, it reduces rice breakage and improves product quality.

[0036] In this embodiment, a third drop hole 621 is opened on the side of the bulk material table 620; part of the rice falls directly into the shaking plate 710 below from the third drop hole 621 on the side of the bulk material table 620, forming a multi-level dispersion path, increasing the diversity of the material flow path, and allowing the rice to enter the cooling area at different heights and positions, further optimizing the material distribution, avoiding local overload, and improving the overall cooling uniformity.

[0037] In this embodiment, a plurality of first drop holes 711, second drop holes 611, and second drop holes 611 are provided, and the plurality of first drop holes 711, second drop holes 611, and second drop holes 611 are uniformly distributed around the bulk structure 6. The number of first drop holes 711 on the same shaking plate 710 is less than the number of second drop holes 611, that is, the distribution of the first drop holes 711 is more sparse, and the diameter of the first drop holes 711 is greater than the diameter of the second drop holes 611; the rice falls gradually through drop holes of different apertures and numbers, the large diameter and small number of first drop holes 711 control the falling speed, and the small diameter and large number of second drop holes 611 realize fine dispersion, and a graded dispersion mechanism regulates the material residence time and dispersion degree through the differences in aperture and number, extends the cooling path, increases the contact time of rice with cold air, and improves the cooling effect.

[0038] Specifically, the diameter of the second feeding hole 611 is larger than the maximum diameter of rice, which can prevent rice from clogging the first feeding hole 711. The diameter of the first feeding hole 711 is preferably 1.5 times the diameter of the second feeding hole 611, so that more rice can pass through the first feeding hole 711 at the same time.

[0039] In this embodiment, the positions of the first feeding holes 711 on adjacent shaking trays 710 are staggered with each other; the positions of the first feeding holes 711 on adjacent shaking trays 710 are staggered, forcing the rice to move laterally during the falling process, extending the movement path, increasing the contact time and area of the rice with the cold air, improving the cooling efficiency, ensuring that each grain of rice is fully cooled, and reducing temperature unevenness.

[0040] In this embodiment, the shock-absorbing structure 8 includes an L-shaped connecting plate 801, the first end of the connecting plate 801 is connected to the inner wall of the shell 1 through a bolt structure 802, and the second end of the connecting plate 801 is mounted on the outside of the mounting rod 740. The outside of the mounting rod 740 corresponding to both sides of the second end of the connecting plate 801 are mounted with a second spring 803, one end of the second spring 803 is against the connecting plate 801, and the other end of the second spring 803 is against the corresponding nut 804 or the bulk plate 610 or the shaking plate 710, and the nut 804 is threadedly connected to the mounting rod 740; the mounting rod 740 is elastically connected to the inner wall of the shell 1 through the connecting plate 801 and the second spring 803. During vibration, the spring buffers the impact, and the nut 804 adjusts the spring preload. The spring shock-absorbing system absorbs vibration energy, reduces the noise and structural damage caused by the rigid connection, reduces the equipment operation noise, improves the structural reliability, and extends the service life.

[0041] In this embodiment, a feed hopper 9 is provided between the feed pipe 2 and the shell 1, the first end of the feed hopper 9 is connected to the feed pipe 2, the second end of the feed hopper 9 is connected to the upper end of the shell 1, and the side of the feed hopper 9 is also connected to the air outlet pipe 5, and a discharge hopper 10 is provided between the discharge pipe 3 and the shell 1, the first end of the discharge hopper 10 is connected to the discharge pipe 3, the second end of the discharge hopper 10 is connected to the lower end of the shell 1, and the side of the discharge hopper 10 is also connected to the air inlet pipe 4, and a leak-proof net 11 is fixedly installed at the connection between the air inlet pipe 4 and the discharge hopper 10; the feed hopper 9 and the discharge hopper 10 are respectively connected to the pipeline and the shell 1, and the leak-proof net 11 at the air inlet pipe 4 prevents rice from entering the blowing system. The bucket-shaped structure optimizes the fluidity of the material inlet and outlet, and the leak-proof net 11 physically intercepts to ensure the safe operation of the equipment, reduce material leakage, protect the blowing equipment, and improve the stability of the system.
