Description

[0002] During rice processing, the friction between rice and equipment components will generate heat, causing the temperature of the rice to rise. If the temperature is not reduced in time, the excessively high temperature may affect the subsequent processing performance of the rice, such as causing it to lose moisture too quickly and causing some subtle changes in its internal structure due to heat. On the other hand, it may also be conducive to the growth and reproduction of microorganisms, affecting the quality of the rice. During the processing, excessively high temperatures may also cause the rice to burst (cracks appear on the surface of the rice grains), reduce the polished rice rate, and affect the appearance quality and yield of the rice.

[0032] 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 to dissipate heat or equip air cooling equipment to dissipate heat. In order to improve the heat dissipation efficiency, the existing method usually requires the rice to be spread out, which usually requires a larger area of ​​spreading position, and the spreading and collection efficiency is low. Therefore, a rice ventilation and cooling device is needed to solve the above problems.

[0033] In view of this, the present application proposes a rice ventilation and cooling device.

[0034] In the examples of this application, refer to Figures 1 to 6 The rice ventilation and cooling device comprises: an input structure 1, a support component 2, a dispersion component 3, a ventilation component 4, an air blowing component 5, an air guiding component 6, and an output structure 7. The input structure 1 is used to convey rice to the dispersion component 3. The support component 2 is used to support the input structure 1, the dispersion component 3, the ventilation component 4, the air blowing component 5, the air guiding component 6, and the output structure 7. The dispersion component 3 is used to disperse the rice. The ventilation component 4 is used to make the dispersed rice communicate with the outside air. The air blowing component 5 is used to blow air to the ventilation component 4. The air guiding component 6 is used to guide the air to blow to the ventilation component 4. The output structure 7 is used to collect and output the rice after heat dissipation. When the input structure 1 conveys the rice to the dispersion component 3, the dispersion component 3 disperses the gathered rice and enters the ventilation component 4 for ventilation. The air blowing component 5 blows air to the ventilation component 4 to increase the air flow rate between the ventilation components 4, so that the rice dissipates heat quickly.

[0035] Specifically, refer to Figure 3 and Figure 6 The ventilation component 4 includes a plurality of channels 410, and a plurality of ventilation holes or ventilation slots 412 are uniformly arranged on the side of the channel 410 along the axis and around the axis. The plurality of channels 410 are arranged obliquely, and the plurality of channels 410 do not intersect with each other. The design arranges a plurality of channels 410 with ventilation holes or ventilation slots 412, and arranges the channels 410 obliquely, so that the rice can be dispersed in each channel 410 and slowly move along the spiral channel 410. In combination with the use of the blowing component 5 and the wind guide component 6, the heat of the rice can be quickly dissipated by the fast-flowing air.

[0036] refer to Figure 1 and Figure 2The support assembly 2 includes a first support plate 210 and a second support plate 220 which are distributed in parallel up and down. The first support plate 210 and the second support plate 220 are connected by a plurality of support columns 230. The plurality of support columns 230 are evenly distributed circumferentially around the axis of the ventilation assembly 4. The second support plate 220 is installed on the platform through a plurality of support legs 240 evenly distributed circumferentially. The other components in the device are supported by the support columns 230 and the support legs 240, and the force between each support column 230 and the support leg 240 is evenly distributed.

[0037] refer to Figure 2 The ventilation component 4 is arranged in the middle of multiple support columns 230, the input structure 1 is connected to the first support plate 210, and the output structure 7 is connected to the second support plate 220. The ventilation component 4 is communicated with the input structure 1 and the output structure 7 respectively, so that the input structure 1 can transport the rice into the ventilation component 4, so that the rice after ventilation and heat dissipation can be transported to the next process through the output structure 7.

[0038] refer to Figure 2 The dispersion component 3 includes a vibrator 310. A vibration plate 320 is arranged between the first support plate 210 and the input structure 1. The vibration plate 320 is installed on the first support plate 210 through a plurality of buffer blocks 330 evenly distributed in the circumferential direction. The buffer block 330 may be a block structure made of rubber material. The buffer block 330 may absorb the vibration on the vibration plate 320 through its own elasticity to prevent the vibration from affecting the structure of the first support plate 210 and the channel 410. The vibration plate 320 is an arc-shaped curved surface structure with a high middle and low surroundings. The vibrator 310 is arranged at the center of the surface of the vibration plate 320 facing the input structure 1. The vibrator 310 may be an electromagnetic vibrator 310 (now The vibrator 310 is used to vibrate the vibration plate 320. The entrances of the corresponding multiple channels 410 on the vibration plate 320 are all provided with hoppers 321. The end of the hopper 321 with a larger diameter is communicated with the side of the vibration plate 320 facing the input structure 1, and the end of the hopper 321 with a smaller diameter is communicated with the entrance of the corresponding channel 410. The vibration plate 320 is driven to vibrate by the vibrator 310, so that the rice moves along the curved surface of the vibration plate 320 toward the outside of the vibration plate 320 until it falls into one of the hoppers 321, and then enters the corresponding channel 410 for heat dissipation.

[0039] refer to Figure 2One end of each of the multiple channels 410 is connected to the first support plate 210, and corresponding channels 410 on the first support plate 210 are provided with feed holes 211, which are aligned with corresponding feed hoppers 321 to ensure that rice can fall into the corresponding feed holes 211 through the feed hopper 321 and finally enter the corresponding channels 410. The other ends of each of the multiple channels 410 are connected to the second support plate 220, and corresponding channels 410 on the second support plate 220 are provided with discharge holes 221, which are communicated with the output structure 7. Multiple fixing frames (not shown in the figure) for fixing the channels 410 are evenly distributed in the middle of the multiple channels 410, and the multiple fixing frames are installed on multiple support columns 230. The setting of the fixing frames can ensure the stability of the structure in the middle of the channels 410, so that the channels 410 can maintain a spiral distribution.

[0040] refer to Figure 2 The input structure 1 includes a feeding hopper 110, which is covered on the vibration plate 320 and fixedly connected to the vibration plate 320. A feeding pipe 120 is connected to the feeding hopper 110 corresponding to the vibrator 310, and the other end of the feeding pipe 120 can be connected to the equipment of the previous process, so that the rice can directly enter the device through the feeding pipe 120 for heat dissipation after the previous process is completed; the output structure 7 includes a discharging hopper 710, which is covered on the second support plate 220, and the discharging hopper 710 is fixedly connected to the second support plate 220. A discharging pipe 720 is connected to the discharging hopper 710, and the other end of the discharging pipe 720 can be connected to the equipment of the next process, so that the rice after heat dissipation can directly enter the next process for processing through the discharging pipe 720.

[0041] refer to Figure 1 and Figure 2 The blowing component 5 includes a plurality of air nozzles 510, which are evenly distributed on the outside of the ventilation component 4. The air nozzles 510 are installed on the support column 230. The air nozzles 510 are tilted downward and face the ventilation component 4. The air nozzles 510 are connected to an air supply device (not shown in the figure) through an air pressure pipe. The air supply device is used to provide compressed air. The compressed air is transported to the air nozzles 510 through the air pressure pipe and finally sprayed toward the ventilation component 4 through the air nozzles 510, which can increase the air flow rate between the ventilation components 4.

[0042] refer to Figure 2 The air guide component 6 includes a plurality of air guide plates 610, which are evenly distributed on the outside of the ventilation component 4. The air guide plates 610 are installed on the support column 230. The cross-section of the air guide plates 610 is an arc-shaped structure, and the concave arc-shaped surface of the air guide plates 610 faces the ventilation component 4. The air guide plates 610 are used to guide the compressed air blown out by the air nozzle 510 to blow toward the ventilation component 4, so that the air blown out through the ventilation component 4 is guided by the air guide plates 610 and blown back to the ventilation component 4, thereby further increasing the air flow rate between the ventilation components 4.

[0043] refer to Figure 4 , Figure 5 and Figure 6 The multiple channels 410 are all in a spiral distribution structure. The channel 410 is composed of a plurality of wires 411 uniformly distributed around the axis. The wires 411 can be steel wires or wires 411 made of other metal materials or non-metallic materials. Ventilation grooves 412 are formed between adjacent wires 411. The width of the ventilation grooves 412 is less than or equal to the minimum radius of the rice, so that the rice can slide smoothly along the channel 410 to avoid the rice being stuck in the ventilation grooves 412.

[0044] Since the channel 410 is composed of a plurality of silk threads 411 evenly distributed around the axis, the arrangement of the corresponding silk threads, the fixing method, the width of the ventilation groove 412 and other process requirements are relatively high, resulting in a relatively high production cost of the channel 410 formed in this manner. In order to reduce the manufacturing cost, the channel 410 can also be set as a spirally distributed pipe-like structure, and a plurality of ventilation holes can be evenly opened on the side of the pipe-like structure along the axis and around the axis, and the diameter of the ventilation holes is less than or equal to the minimum radius of rice. This structure can replace the above-mentioned channel 410 structure composed of silk threads 411.

[0045] refer to Figure 3 and Figure 4 The multiple channels 410 are divided into multiple annularly distributed channel 410 groups, and the number of channels in each channel 410 group is different. The channel 410 group with a large number of channels 410 is located outside the channel 410 group with a small number of channels 410. The spacing between the channels 410 in the channel 410 group located outside is smaller than the spacing between the channels 410 in the channel 410 group located inside, so that the heat dissipation between the rice located in the inner channel 410 and the rice located in the outer channel 410 is more uniform.

[0046] The technical solution of the present application is provided by setting an input structure, a support component, a dispersion component, a ventilation component, an air blowing component, an air guiding component, and an output structure, wherein the input structure is used to transport rice to the dispersion component, the support component is used to support the input structure, the dispersion component, the ventilation component, the air blowing component, the air guiding component, and the output structure, the dispersion component is used to disperse the rice, the air blowing component is used to blow air to the ventilation component, the air guiding component is used to guide the air to blow toward the ventilation component, and the output structure is used to collect and output the heat-dissipated rice, wherein the ventilation component includes a plurality of channels, and a plurality of ventilation holes or ventilation grooves are uniformly provided on the side of the channel along the axis and around the axis, and the plurality of channels are all inclinedly arranged, and the plurality of channels do not intersect with each other; when the input structure transports the rice to the dispersion component, the dispersion component will disperse the gathered rice and enter each channel, and since the channel is an inclined structure, the rice will flow along the inclined channel Move slowly, the blowing component blows air to the ventilation component to increase the air flow rate between the ventilation components, and the fast-flowing air shuttles between the various channels. Since a plurality of ventilation holes or ventilation slots are provided on the channel, the fast-flowing air will enter the channel through the ventilation holes or ventilation slots and contact with the rice moving in the channel, so that the rice can quickly dissipate heat. The design sets a plurality of channels with ventilation holes or ventilation slots so that the rice can be dispersed in various channels and move slowly along the inclined channels. Combined with the use of the blowing component and the wind guide component, the rice can be quickly cooled by the fast-flowing air. Since the rice is in a state of continuous movement, the device can continuously dissipate the heat for the rice, which can effectively improve the efficiency of the heat dissipation of the rice. Moreover, the rice will continue to move along the inclined channel, and the rice does not need to be spread out during the heat dissipation process, which can effectively reduce the space required for the heat dissipation of the rice.
