A stir-frying part 33 is arranged below the buffer 32, and the rice grains passing through the buffer 32 fall onto the stir-frying part 33 for shaking, stir-frying and uniform drying. When the rice seeds need to be stored for a long time, their water content needs to be reduced to avoid mold or germination due to long-term stacking and storage.

The uppermost horizontal positions of the first buffer angle steel 321, the buffer column 322, and the second buffer angle steel 323 are stepped from low to high. The rice transported from the circulation module 4 falls onto the buffer bucket, and the rice slides down along the buffer bucket. The sliding rice hits the first buffer angle steel 321 and is The buffer angle steel 321 is used for diversion, wherein the rice is further decelerated when sliding on the surface of the first buffer angle steel 321, and the rice that continues to slide hits the buffer column 322 and is blocked and decelerated, and the decelerated rice hits the second buffer angle steel 323 and is diverted by the second buffer angle steel 323, wherein the rice is further decelerated when sliding on the surface of the second buffer angle steel 323, and finally the rice falls from the gap between the buffer cone 324 and the drying drum 31, and the stepped first buffer angle steel 321, buffer column 322 and second buffer angle steel 323 are arranged in a bowl-shaped structure to collect rice as much as possible.

[0025] A vertical push piece 34 is arranged below the sliding cone 333. The vertical push piece 34 includes a guide chamber 341 and an impeller component 342. The guide chamber 341 spirals upward on the inner wall of the drying cylinder 31, wherein the bottom end of the guide chamber 341 is connected to the conveying module 5, and the top end of the guide chamber 341 is sealed. The hot air sent by the conveying module 5 is discharged from the air outlet on the side of the guide chamber 341, and the discharged hot air blows the impeller component 342 to rotate. The rotating impeller component 342 utilizes the upper end protrusion to cooperate with the groove below the sliding cone 333 to drive the sliding cone 333 to move up and down. The impeller component 342 includes an impeller plate 3422, wherein the impeller plate 3422 rotates on the surface of the circular tube 41, and the surface of the impeller plate 3422 is evenly provided with impeller blades 3421, wherein the air outlet of the guide chamber 341 is aligned with the impeller blades 3421, and the sliding cone 333 is The surface of the circular tube 41 slides up and down (only vertical sliding and cannot rotate), an arc-shaped groove is opened under the sliding cone 333, and a top strip 3423 corresponding to the arc-shaped groove is fixedly installed on the upper end of the impeller plate 3422. The conveying module 5 blows hot air into the guide cavity 341 in the drying cylinder 31, wherein the guide cavity 341 spirally rises to allow the incoming airflow to spirally rise as well. Since the upper end of the guide cavity 341 is sealed, the spirally upward airflow is ejected from the air outlet on the side of the guide cavity 341 to blow the impeller blades 3421, and the impeller blades 3421 drive the impeller plate 3422 to rotate on the surface of the circular tube 41. During the rotation of the impeller plate 3422, the top strip 3423 continuously and alternately enters and exits the arc-shaped groove, so the sliding cone 333 continuously moves up and down, and the push rod 334 at the upper end of the sliding cone 333 also moves up and down to lift up the elastic cloth cover.

When the discharge cavity 45 is aligned with the discharge groove 4 3, the rice seeds transported up by the auger 42 enter the discharge cavity 45 from the discharge trough 43 and then freely fall from the bottom of the discharge cavity 45. The side of the sleeve 44 is also connected with a discharge pipe 46, wherein the free end of the discharge pipe 46 tilts downward and extends out of the drying cylinder 31, and the rice at the bottom of the drying cylinder 31 enters the circular tube 41 along the feeding port of the circular tube 41, and is transported upward by the rotation of the auger 42. The rice transported upward enters the discharge cavity 45 from the discharge trough 43 and then freely falls from the bottom of the discharge cavity 45. When the rice is dried, the discharge pipe 46 can be moved (by a bamboo pole or a ladder) to drive the sleeve 44 to rotate on the surface of the circular tube 41, and then the discharge pipe 46 is aligned with the discharge trough 43, so that the rice transported upward enters the discharge pipe 46 from the discharge trough 43 and is discharged.

A water filling port is provided on the side of the first water tank 222, and a liquid level gauge is also provided on the side of the first water tank 222. By observing the liquid level gauge, it can be judged whether the first water tank 222 needs to be replenished with water. The fuel combustion in the heating chamber 211 The first water tank 222 is heated by combustion, and the water in the first water tank 222 is heated to generate high-temperature steam. The high-temperature steam enters the heat source elbow 224 along the heat source straight pipe 223, and the heat dissipation fins 225 on the surface of the heat source elbow 224 can quickly exchange heat with the air. The fan in the conveying module 5 draws the outside air into the heat source chamber 221 from the air pipe 227, and the air is heated in the heat source chamber 221 (because it is heat exchanged with water vapor, the air temperature is lower than the direct heating temperature of the combustion to avoid carbonization and inactivation of rice caused by excessive temperature), the steam after heat exchange enters the cooling zone of the collecting pipe 226 from the heat source elbow 224, and the cooled steam and water mixture is discharged through the circulation component 24, wherein the setting of the heat source elbow 224 can increase the contact area between air and steam.

The smoke burning in the heating chamber 211 is discharged from the exhaust pipe 232. The heat exchange fins 233 on the surface of the exhaust pipe 232 accelerate the contact area with the second water tank 231 to improve the heat exchange efficiency of the high-temperature gas in the exhaust pipe 232. The water in the second water tank 231 is heated to generate steam, and the steam enters the first water tank 222 from the steam pipe 234. The steam is ejected from the first water tank 222 to promote the circulation of water in the first water tank 222, accelerate the boiling of water in the first water tank 222 to generate steam, and improve the steam generation efficiency of the first water tank 222.

[0029] Reference Figure 7 and Figure 8 As shown, the port of the steam pipe 234 is sealed, and an agitator 235 is arranged on the surface of the steam pipe 234, wherein the agitator 235 comprises a rotating ring 2351 rotatably sleeved on the surface of the steam pipe 234, and stirring fins 2352 are evenly arranged on the surface of the rotating ring 2351. An inclined hole 2353 is opened on the surface of the steam pipe 234. The steam pipe 234 is sealed so that the steam can only be discharged from the inclined hole 2353, and the inclined hole 2353 is aligned with the stirring fins 2352. When the steam is discharged from the inclined hole 2353, on the one hand, it can stir the water in the first water tank 222 to make it evenly heated and accelerate boiling. On the other hand, the steam discharge can drive the stirring fins 2352 to rotate. During the rotation of the stirring fins 2352, the water in the first water tank 222 is stirred to quickly generate steam. At the same time, the speed of the steam spraying out of the water surface of the first water tank 222 can be reduced, so as to increase the contact time between the steam and the water in the first water tank 222 to improve the heat exchange efficiency.

The cooled steam and water mixture passes through the first circulation air pipe 241, the switching member 243, the first circulation air pipe 241, the second circulation air pipe 244, and the spray pipe 246. The secondary circulation air pipe 244 and the ejection pipe 246 are ejected from the smoke exhaust pipe 232. As the high-speed ejected steam is discharged from the smoke exhaust pipe 232, the high-speed gas flow reduces the air pressure at the smoke exhaust pipe 232, thereby making the external air pressure of the smoke exhaust pipe 232 less than the internal air pressure. Under the action of the air pressure difference, the smoke exhaust efficiency of the smoke exhaust pipe 232 is accelerated, thereby improving the combustion progress in the heating chamber 211, thereby accelerating the generation of steam. The steam generation speed is accelerated, the exhaust speed of the steam in the smoke exhaust pipe 232 is increased, and the combustion speed is continuously improved in this cycle.

At the same time, the plug cone 253 may have spiral grooves on its surface, which can drive the plug cone 253 to rotate when steam is ejected. The spiral grooves on the rotating plug cone 253 guide the steam, so that a thicker spray jet is mixed in the steam cone spray. The thicker spray jet rotates and ejects to wash away the dust adhered to the inside of the smoke hood 251. A scraper ring 256 is provided on the surface of the shaft 254, wherein the scraper ring 256 is an arc-shaped structure that can guide the ejected steam to the exhaust window 255 for discharge.

[0033] Working principle: when rice seeds need to be stored for a long time, their moisture content needs to be reduced to avoid mold or germination due to long-term stacking and storage. The rice seeds that need to be dried are poured into the drying drum 31 (they can be poured into the drying drum 31 manually using a ladder or can be transported to the drying drum 31 through a belt conveyor), the heating module 2 generates heat to generate high-temperature gas (electric heating can be used, gaseous dye combustion heating can be used, or solid fuel combustion can be used for heating), the conveying module 5 conveys the high-temperature gas generated by the heating module 2 into the drying drum 31 (the conveying module 5 can use a combination of an exhaust fan and an air duct to draw the high-temperature gas in the heating module 2 into the drying drum 31), and the high-pressure and high-temperature hot air entering the drying drum 31 dries the rice seeds; Since the drying drum 31 is provided with a circulation module 4 inside, the rice seeds at the bottom can be transported upward, and then the rice seeds are thrown down from a high place to make them fall freely into the drying drum 31. The rice seeds are more dispersed during the falling process and can better contact with the hot air, thereby improving the drying efficiency; the rice grains transported from the circulation module 4 fall onto the buffer bucket, and the rice grains slide down along the buffer bucket. The sliding rice grains hit the first buffer angle steel 321 and are diverted by the first buffer angle steel 321, wherein the rice grains at the first buffer angle steel 32 1 further decelerates when sliding on the surface, and the rice that continues to slide hits the buffer column 322 and is blocked and decelerated. The decelerated rice hits the second buffer angle steel 323 and is diverted by the second buffer angle steel 323, wherein the rice further decelerates when sliding on the surface of the second buffer angle steel 323, and finally the rice falls from the gap between the buffer cone bucket 324 and the drying drum 31. The stepped first buffer angle steel 321, the buffer column 322 and the second buffer angle steel 323 are arranged in a bowl-shaped structure to collect rice as much as possible; The rice that falls from the gap between the buffer cone 324 and the drying cylinder 31 falls onto the stir-frying bucket 331, and slides down the stir-frying bucket 331 under the action of gravity, and then slides into the elastic cloth bag in the storage hole 332 for storage, and is driven to move up and down by the sliding cone 333, so that the push rod 334 pokes the elastic cloth bag so that the rice in the elastic cloth bag is flipped up to achieve the effect of stir-frying, and the rice is stir-fried by vibration to increase the contact area with the hot air, so as to avoid uneven heating of the rice accumulation, and also to increase the time the rice is in the air to improve the drying efficiency, and the conveying module 5 blows the hot air into the guide cavity 341 in the drying cylinder 31, wherein the guide cavity 341 spirally rises so that the incoming airflow can also spirally rise, and since the upper end of the guide cavity 341 is sealed, the spiral upward airflow is ejected from the air outlet on the side of the guide cavity 341 to blow the impeller blades 3421 The impeller blades 3421 drive the impeller plate 3422 to rotate on the surface of the circular tube 41. During the rotation of the impeller plate 3422, the top bar 3423 continuously and alternately enters and exits the arc-shaped groove, so the sliding cone 333 continuously moves up and down, and the push rod 334 at the upper end of the sliding cone 333 also moves up and down to lift the elastic cloth cover. The rice at the bottom of the drying cylinder 31 enters the circular tube 41 along the feeding port of the circular tube 41, and is transported upward by the rotation of the auger 42. The rice transported upward enters the discharge cavity 45 from the discharge trough 43 and then falls freely from the bottom of the discharge cavity 45. When the rice is dried, the discharge pipe 46 can be moved (by a bamboo pole or with the help of a ladder) to drive the sleeve 44 to rotate on the surface of the circular tube 41, and then the discharge pipe 46 is aligned with the discharge trough 43, so that the rice transported upward enters the discharge pipe 46 from the discharge trough 43 and is discharged.

[0034] The fuel combustion in the heating chamber 211 heats the first water tank 222, and the water in the first water tank 222 is heated to generate high-temperature steam. The high-temperature steam enters the heat source elbow 224 along the heat source straight pipe 223. The heat dissipation fins 225 on the surface of the heat source elbow 224 can quickly exchange heat with the air. The fan in the conveying module 5 draws the outside air into the heat source chamber 221 from the air pipe 227. The air is heated in the heat source chamber 221 (because it is heat exchanged with water vapor, the air temperature is lower than the direct heating temperature of the combustion to avoid carbonization and inactivation of rice due to excessive temperature). The steam after heat exchange enters the cooling zone in the collecting pipe 226 from the heat source elbow 224, and the cooled steam is mixed with water. The mixture is discharged through the circulation component 24, wherein the setting of the heat source elbow 224 can increase the contact area between air and steam, and the smoke burning in the heating chamber 211 is discharged from the exhaust pipe 232. The heat exchange fins 233 on the surface of the exhaust pipe 232 accelerate the contact area with the second water tank 231 to improve the heat exchange efficiency of the high-temperature gas in the exhaust pipe 232. The water in the second water tank 231 is heated to generate steam, and the steam enters the first water tank 222 from the steam pipe 234. The steam is ejected from the first water tank 222 to promote the circulation of water in the first water tank 222, accelerate the boiling of water in the first water tank 222 to generate steam, and improve the steam generation efficiency of the first water tank 222. The steam pipe 234 is sealed so that the steam can only come out The steam is discharged from the inclined hole 2353, and the inclined hole 2353 is aligned with the stirring fin 2352. When the steam is discharged from the inclined hole 2353, on the one hand, it can stir the water in the first water tank 222 to make it evenly heated and accelerate boiling. On the other hand, the steam discharge can drive the stirring fin 2352 to rotate. During the rotation of the stirring fin 2352, the water in the first water tank 222 is stirred to quickly generate steam. At the same time, the speed of the steam spraying out of the water surface of the first water tank 222 can be reduced, and the contact time between the steam and the water in the first water tank 222 can be increased to improve the heat exchange efficiency. The cooled steam and water mixture passes through the first circulation air pipe 241, the switching member 243, the second circulation air pipe 244 and the ejection pipe 24 6 is ejected from the smoke exhaust pipe 232. As the high-speed ejected steam is discharged from the smoke exhaust pipe 232, the high-speed gas flow reduces the air pressure at the smoke exhaust pipe 232, thereby making the external air pressure of the smoke exhaust pipe 232 less than the internal air pressure. Under the action of the air pressure difference, the smoke exhaust efficiency of the smoke exhaust pipe 232 is accelerated, thereby improving the combustion progress in the heating chamber 211, thereby accelerating the generation of steam. The steam generation speed is accelerated, and the exhaust speed of the incoming steam in the smoke exhaust pipe 232 is increased. This cycle continuously increases the combustion speed; the steam is ejected from between the conical tube 252 and the plug cone 253 to form a conical spray structure, and the conical spray structure is combined with the dust discharged from the smoke exhaust pipe 232 to form water droplets, thereby reducing the pollution caused by large particles of smoke during combustion.At the same time, the plug cone 253 may have a spiral groove on its surface, and when steam is ejected, the plug cone 253 can be driven to rotate. The spiral groove on the surface of the rotating plug cone 253 guides the steam, so that a thicker spray jet is mixed in the steam cone spray, and the thicker spray jet rotates and ejects to wash out the dust adhered to the inside of the smoke hood 251. The switching component includes a shell 2431 installed in the heat source chamber 221, wherein an operating chamber 2432 is arranged inside the shell 2431, and a rotating shaft 2433 is rotatably arranged in the operating chamber 2432, wherein two blocking blades 2434 are fixedly connected to one side of the rotating shaft 2433, and two switching blades 2435 are arranged on the other side of the rotating shaft 2433, and the blocking blades 2434 are divided into an upper blocking blade and a lower blocking blade according to their positions, and the switching blades 2435 are divided into an upper switching blade and a lower switching blade according to their positions. The rotating shaft 2433 is controlled to rotate by a servo motor. When the upper blocking blade blocks the entrance of the first circulating air pipe 241 in the operating chamber 2432, The upper switching piece also blocks the outlet of the second circulating air pipe 244 in the operating chamber 2432. At this time, the lower blocking piece does not block the inlet of the first circulating water pipe 242 in the operating chamber 2432, and the upper switching piece does not block the outlet of the second circulating air pipe 244 in the operating chamber 2432. The high-pressure steam sends the condensed water in the collection pipe 226 along the first circulating water pipe 242, the operating chamber 2432, and the second circulating water pipe 245 into the second water tank 231 for reuse. When the upper blocking piece does not block the first circulating water pipe When the tube 241 enters the operating chamber 2432, the upper switching piece does not block the outlet of the second circulating air pipe 244 in the operating chamber 2432. At this time, the lower sealing piece blocks the entrance of the first circulating water pipe 242 in the operating chamber 2432, and the upper switching piece also blocks the outlet of the second circulating air pipe 244 in the operating chamber 2432. High-pressure steam will be sent from the collecting pipe 226 along the first circulating air pipe 241, the operating chamber 2432, and the second circulating air pipe 244 into the smoke exhaust pipe 232 to increase the smoke exhaust rate.
