Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rice drying, and in particular to a high-efficiency rice drying device. Background Art
[0002] If the moisture content of the newly harvested rice is high, if it is not dried within a fixed time, the grains will germinate and mold, and produce aflatoxin, which will not only cause cancer if eaten by humans, but if the poisonous rice is eaten by livestock and poultry, the toxins will still remain in the body of humans who eat the livestock and poultry. Therefore, it must be dried immediately after harvesting, and should be dried to a lower moisture content when stored. The high-efficiency rice drying device is a device specifically used for drying rice.
[0003] Compared with the actual use process, the existing high-efficiency rice drying devices, one of which is to set a stirring mechanism in the middle of the storage mechanism, and then heat the storage device to make the rice inside the storage mechanism evaporate quickly, and then discharge the water vapor to the outside through a fan to achieve the drying of the rice. However, this heating method will cause the rice that is in direct contact with the inner wall of the storage device to die due to long-term contact with the heat source, which will affect the drying of the seed grain. At the same time, the rotating stirring device cannot fully turn the rice, which will reduce the drying efficiency of the rice.
[0004] Therefore, in order to solve the above problems, the present application provides a rice efficient drying device.

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.
[0020] Embodiment 1
[0021] Reference Figure 1-Figure 3, a rice efficient drying device comprises a drying tank 1, a centrifugal pump 2 is installed through a base in the middle of the top of the drying tank 1, and a circulation pipe 3 is connected to the feeding end and the discharging end of the centrifugal pump 2. In order to realize the circulation of rice and accelerate the contact area between a single rice and the air, an air inlet pipe 4 is connected to the top of one end of the outer side of the drying tank 1, and a heating box 5 is connected in the middle of the air inlet pipe 4. A heater 6 is installed through the base on the outer side of one end of the heating box 5, and a resistance wire 7 is connected to the inner side of the heating box 5. The power input end of the heater 6 is connected to the power output end of the external control terminal, and the power output end of the heater 6 is connected to the power input end of the resistance wire 7. A convection pipe 8 is connected to the top of the other end of the outer side of the drying tank 1, and the air inlet end of the air inlet pipe 4 and the air outlet end of the convection pipe 8 both extend through and extend to the inner side of the drying tank 1, and the air inlet end of the air inlet pipe 4 and The outlet ends of the convection tube 8 are at the same horizontal height, and a fan 9 is placed at the bottom end of the outer side of one end of the drying tank 1. In order to dry the rice by convection hot air, the air inlet end of the fan 9 is connected to the outlet end of the convection tube 8, and a cache sieve plate 10 is welded to the top end of the inner side of the drying tank 1. The feeding end of the circulation pipe 3 at the feeding end of the centrifugal pump 2 passes through the discharge baffle 13 and extends to the inner side of the drying tank 1. The discharge end of the circulation pipe 3 at the discharge end of the centrifugal pump 2 passes through and extends to the top end of the inner side of the drying tank 1, and the discharge end of the circulation pipe 3 is located at the top of the cache sieve plate 10. In order to slow down the falling speed of the rice and speed up the drying speed of the rice, a feed hopper 11 is welded to the outer side of one end of the drying tank 1, and a closing plug 12 is embedded on the inner side of the feed end of the feed hopper 11. A discharge baffle 13 is spirally fixed to the bottom end of the drying tank 1, and a support frame 14 is installed at the bottom end of the outer side of the drying tank 1.
[0022] Working principle: first, the operator opens the sealing plug 12 embedded at the feed end of the feed hopper 11 welded on the outside of one end of the drying tank 1, and then pours the rice to be dried into the drying tank 1 through the feed hopper 11. After all the rice is poured in, the operator embeds the sealing plug 12 into the feed hopper 11 again, and then the operator starts the centrifugal pump 2, the heater 6 and the fan 9. First, the centrifugal pump 2 will extract the rice stored in the drying tank 1 from the inner bottom end of the drying tank 1 through the circulation pipe 3 connected to its feed end, and then transport it back to the drying tank 1 through the circulation pipe 3 connected to the discharge end of the centrifugal pump 2. The rice entering the drying tank 1 will first enter the cache sieve plate 10 welded on the inner top of the drying tank 1, and then leak back to the drying tank 1 through the discharge port at the bottom end of the cache sieve plate 10, so that the flow of rice can be achieved;
[0023] During this period, the heater 6 will heat the resistance wire 7 connected to its power output end, and the started fan 9 will draw air toward the inside of the drying tank 1 through the convection tube 8 connected to its air inlet end, and the drying tank 1 will be ventilated through the air inlet tube 4. During this period, the resistance wire 7 installed on the inner side of the heating box 5 in the middle of the air inlet tube 4 will heat the air entering the drying tank 1, and because the air inlet end of the convection tube 8 and the air outlet end of the air inlet tube 4 are located on the same horizontal line and correspond to each other, the hot air will quickly form convection, heat the buffer sieve plate 10 between the air inlet end of the convection tube 8 and the air inlet tube 4, and the hot air will evaporate the moisture carried by the rice and take the moisture away from the inside of the drying tank 1. This design can make the rice flow inside the storage mechanism, can prevent the occurrence of undried rice, and thus can speed up the efficiency of rice drying.
[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
