DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: referring to Figure 1 - Figure 8 The present invention discloses a fermented grains mixing device for light wine brewing, comprising a storage cylinder 1; Also includes: A mixing assembly 2 is arranged in the storage tube 1. The mixing assembly 2 includes a filter tube 21 which is horizontally rotatably mounted in the storage tube 1 through a bearing. A driving mechanism 22 is arranged at one end of the filter tube 21 for driving the filter tube 21 to rotate. A scraping mechanism 23 is arranged in the filter tube 21. The material spreading assembly 3 is arranged on the storage tube 1, and the material spreading assembly 3 includes a conduit 31. The conduit 31 is arranged at the axial position of the filter tube 21, and both ends of the conduit 31 are fixedly passed through the tube wall of the storage tube 1, and a rectangular plate 32 is provided on the top side of the conduit 31, and the bottom end of the rectangular plate 32 is fixedly connected to the outer wall of the conduit 31, and a rectangular groove 33 communicating with the inside of the conduit 31 is jointly provided in the rectangular plate 32 and the tube wall of the conduit 31, and a storage hopper 34 is installed at the air inlet of the conduit 31, and a grinding mechanism 35 is provided in the storage hopper 34 for grinding the koji, and a gas internal circulation mechanism 36 is provided on the top side of the storage hopper 34 for extracting the gas in the filter tube 21 and injecting the gas into the storage hopper 34.

[0021] In this embodiment, please refer to Figure 3-5 As shown, the filter tube 21 is used for storing raw materials, and the driving mechanism 22 drives the filter tube 21 to rotate, and the filter tube 21 rotates slowly so that the raw materials at the bottom of the filter tube 21 are turned over to complete the mixing of the fermented grains. Figure 4 , Figure 6 and Figure 7As shown, the rapidly rotating filter tube 21 drives the raw material to adhere to the inner wall of the filter tube 21 through centrifugal force and rotates with the filter tube 21. The two ends of the rectangular plate 32 are fixedly connected to the inner wall of the storage tube 1, so that the installation of the rectangular plate 32 and the guide tube 31 is more stable. In the process of the raw material rotating with the filter tube 21, the rectangular plate 32 can scrape off the excess raw material on the inner wall of the filter tube 21, so that the raw material is evenly spread on the inner wall of the filter tube 21, so that the distiller's yeast sprinkled by the spreading component 3 can be spread on the raw material more evenly, and the mixing effect of the fermented grains is good. Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the koji fragments are placed in the storage hopper 34, and the gas internal circulation mechanism is started, so that the gas in the storage cylinder 1 and the storage hopper 34 circulates continuously. During the flow of the gas in the storage hopper 34, the grinding mechanism 35 is driven to grind the koji fragments into koji powder. Then the air flow carries the koji powder through the conduit 31 and the rectangular groove 33 and blows on the raw materials on the inner wall of the filter tube 21 in turn, so that the koji is evenly sprinkled on the raw materials to prevent the koji fragments from being mixed in the raw materials during the mixing process of the mash, which affects the mixing effect of the mash.

[0022] In a further preferred embodiment of the present invention, Figure 3 As shown, the driving mechanism 22 includes a motor 221, which is fixedly mounted on the top of the storage tube 1 away from the storage hopper 34. The driving end of the motor 221 is inserted between the filter tube 21 and the inner wall of the storage tube 1 and is fixedly mounted with a gear 222. The outer peripheral side of the filter tube 21 is fixedly sleeved with a gear ring 223, and the gear ring 223 is meshed and connected with the gear 222. In this embodiment, please refer to Figure 3 As shown, during the use of the device, the motor 221 starts the driving gear 222 to rotate, and drives the filter tube 21 to rotate through the gear ring 223. Since the diameter of the gear ring 223 is much larger than the diameter of the gear 222, the axial driving force of the motor 221 on the filter tube 21 can be greatly enhanced.

[0023] In a further preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, a rectangular strip 37 is fixedly mounted on the top of the rectangular plate 32, and the rectangular strip 37 is gap-matched with the inner wall of the filter tube 21, and the length of the rectangular strip 37 is the same as the length of the rectangular plate 32; In this embodiment, please refer to Figure 6 and Figure 7 As shown, the setting of the rectangular strip 37 can reduce the distance between the rectangular plate 32 and the inner wall of the filter tube 21, so that after the raw material is spread on the inner wall of the filter tube 21, there is a gap of corresponding size between the rectangular groove 33 and the spread raw material, so as to facilitate the airflow to carry the koji powder out of the rectangular groove 33.

[0024] In a further preferred embodiment of the present invention, Figure 4 and Figure 8 As shown, the grinding mechanism 35 includes a grinding top plate 351 and a grinding bottom plate 352, which are arranged in the storage hopper 34 from top to bottom, and the outer peripheral wall of the grinding top plate 351 is fixedly connected to the inner wall of the storage hopper 34, the center position in the grinding top plate 351 is hollow, and both ends of the inner hole of the grinding top plate 351 are flared, the outer peripheral wall of the grinding bottom plate 352 is gapped with the inner wall of the storage hopper 34, and the top of the grinding bottom plate 352 is conical and inserted into the inner hole of the grinding top plate 351 to gap-match with the inner wall of the bottom opening of the inner hole of the grinding top plate 351; In this embodiment, please refer to 4 and Figure 8 As shown, after the koji fragments are stuffed into the storage hopper 34, the koji fragments slide into the gap between the grinding top plate 351 and the grinding bottom plate 352 along the arc surface of the opening at the top end of the inner hole of the grinding top plate 351, and then the grinding process of the koji fragments is completed by the rotating grinding bottom plate 352 cooperating with the grinding top plate 351, and the koji fragments are ground into koji powder. Then, the air flow carries the koji powder through the gap between the grinding top plate 351 and the grinding top plate 351, the conduit 31 and the rectangular hole in turn, and blows on the raw materials on the inner wall of the filter tube 21 in turn, so that the koji powder is evenly sprinkled on the spread raw materials.

[0025] In a further preferred embodiment of the present invention, Figure 3 and Figure 8 As shown, a cylinder cover 353 is provided at the top of the storage hopper 34, and a joint 354 is rotatably installed and penetrated at the center of the cylinder cover 353; In this embodiment, please refer to Figure 2 and Figure 8 As shown, the operator twists the cylinder cover 353 to screw the cylinder cover 353 out of the top opening of the storage hopper 34. Since the joint will not rotate with the cylinder cover 353, the rotation of the cylinder cover 353 will not affect the connection between the cylinder cover 353 and the gas internal circulation mechanism. After the cylinder cover 353 is screwed out, the operator can stuff the koji fragments into the storage hopper 34 through the top opening of the storage hopper 34, and finally screw the cylinder cover 353 into the top opening of the storage hopper 34 again to complete the koji loading process. The koji loading operation is simple, and during the mash mixing operation, different koji loading processes can be carried out, so that the device can complete the mixing of multiple kojis and raw materials at one time.

[0026] In a further preferred embodiment of the present invention, Figure 8 and Fig. 9As shown, a support rod 355 is vertically fixedly installed at the center position of the bottom side of the grinding bottom plate 352, and an impeller 356 is fixedly installed at the bottom end of the support rod 355, and the impeller 356 is located in the bottom end opening of the storage hopper 34 and is gap-matched with the inner wall of the bottom end opening of the storage hopper 34. A support ring 357 is rotatably sleeved on the outer peripheral side of the support rod 355 through a bearing, and the outer peripheral wall of the support ring 357 is fixedly connected to the inner wall of the storage hopper 34 through a plurality of connecting rods 358; In this embodiment, please refer to Figure 8 and Fig. 9 As shown, the arrangement of the support ring 357 and the connecting rod 358 can stably support the support rod 355 and the grinding bottom plate 352 without affecting the rotation of the support rod 355, so that the grinding bottom plate 352 is in a stable horizontal state; When the airflow flows from the storage hopper 34 into the conduit 31, the airflow blows on the impeller 356, thereby applying an axial thrust to the support rod 355 through the impeller 356 to drive the grinding base plate 352 to rotate continuously without connecting an additional power source, thereby reducing the use cost of the device.

[0027] In a further preferred embodiment of the present invention, Figure 3 and Figure 8 As shown, the gas internal circulation mechanism 36 includes an air pump 361, which is arranged on the top side of the storage hopper 34, and the air pump 361 is fixedly connected to the outer wall of the storage tube 1, and the exhaust end of the air pump 361 is connected to the air inlet end of the joint 354 through a soft tube 362; In this embodiment, please refer to Figure 3 , Figure 8 and Fig.10 As shown, during the use of the device, the air pump 361 starts to continuously extract the gas in the storage cylinder 1 and injects the gas into the storage hopper 34. Then the gas passes through the inner hole of the grinding top plate 351, the gap between the grinding top plate 351 and the grinding bottom plate 352, the conduit 31 and the rectangular groove 33, and blows on the raw materials on the inner wall of the filter tube 21. During the flow of the airflow in the storage hopper 34, a thrust can be applied to the koji fragments, pushing the koji fragments into the gap between the grinding top plate 351 and the grinding bottom plate 352, thereby facilitating the grinding of the koji fragments by the grinding top plate 351 and the grinding bottom plate 352.

[0028] In a further preferred embodiment of the present invention, Figure 3 , Figure 7 and Fig.10 As shown, an air extraction pipe 363 is provided on the top side of the filter tube 21, and the bottom end opening of the air extraction pipe 363 is expanded and contacts the outer peripheral wall of the filter tube 21, and the air extraction end of the air pump 361 extends into the air extraction pipe 363 and is fixedly connected to the pipe wall of the air extraction pipe 363; In this embodiment, please refer to Figure 3 , Figure 7 and Fig.10 When the air pump 361 extracts gas, it directly extracts gas from the exhaust pipe 363, so that a negative pressure chamber is formed in the exhaust pipe 363. At this time, a large pressure difference is formed on both sides of the tube wall of the filter tube 21 on the top side of the rectangular plate 32. After the air flow blows on the raw material, the air flow passes through the gaps between the raw materials and some filter holes of the filter tube 21 and flows into the exhaust pipe 363 to replenish the gas lost in the exhaust pipe 363, so that the air flow carries the koji powder and is almost completely blown onto the raw material, thereby preventing the gas from carrying the koji powder and scattering onto the inner wall of the storage cylinder 1.

[0029] In a further preferred embodiment of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the scraping mechanism 23 includes a scraper 233, a cover 231 is fixedly installed through the bottom of the other side of the storage cylinder 1, and the cover 231 is located below the guide tube 31, and a storage groove 232 is opened on the inner wall of the storage cylinder 1 away from the storage hopper 34, and the inner bottom wall of the storage groove 232 is coplanar with the inner wall of the filter tube 21, and the scraper 233 is slidably installed in the storage groove 232; In this embodiment, please refer to Figure 3 and Figure 4 As shown, the cover 231 is fixed to the storage barrel 1 by bolts. When using the device, the operator unscrews the bolts on the cover 231, then pulls the cover 231 out of the wall of the storage barrel 1, and then inserts the raw material into the filter tube 21 from the corresponding opening of the storage barrel 1. After a specific amount of raw material is inserted into the filter tube 21, the cover 231 is reinserted into the opening of the storage barrel 1, and finally the bolts are reinserted into the wall of the storage barrel 1 to complete the fixation of the cover 231 and the storage barrel 1. The loading operation of the device is completed, and the loading operation of the raw material, i.e., rice or sorghum, is simple.

[0030] In a further preferred embodiment of the present invention, Figure 6 As shown, the top of the scraper 233 is in a clamp-shaped configuration and is slidably sleeved on the outer peripheral side of the conduit 31. A connecting plate 234 is provided between the scraper 233 and the cover 231, and the two ends of the connecting plate 234 are fixedly connected to the scraper 233 and the cover 231 respectively; In this embodiment, please refer to Figure 4 As shown, after the mixing operation of the koji is completed, the operator removes the cover 231 from the storage cylinder 1 and pulls the cover 231 away from the storage cylinder 1. At this time, due to the pulling of the scraper 233 by the connecting plate 234, the scraper 233 moves along with the cover 231, scrapes the inner wall at the bottom of the filter tube 21, and pushes the mash out of the opening of the storage cylinder 1, completing the unloading process of the mash in the device.

[0031] Working principle: When the improved fermented grains mixing device is used, the operator first unscrews the bolts on the cover 231, then pulls the cover 231 out of the wall of the storage tube 1, and then inserts the raw material into the filter tube 21 from the opening of the storage tube 1. After a specific amount of raw material is inserted into the filter tube 21, the cover 231 is then reinserted into the opening of the storage tube 1. Due to the push of the connecting plate 234 on the scraper 233, the scraper 233 is directly pushed into the storage tank 232 for storage. Finally, the bolts are reinserted into the wall of the storage tube 1 to complete the fixation of the cover 231 and the storage tube 1, and the loading operation of the device is completed. After the loading operation of the device is completed, the motor 221 starts the driving gear 222 to rotate, and drives the filter tube 21 to rotate through the gear ring 223, and the speed of the filter tube 21 slowly increases until the speed of the filter tube 21 reaches the threshold. In the process of slowly increasing the speed of the filter tube 21, the raw material is always located at the bottom of the filter tube 21 due to the effect of its own gravity, and the raw material is driven by the filter tube 21 to continuously turn over in the filter tube 21, so that the raw material is more evenly distributed at the bottom of the filter tube 21. After the speed of the filter tube 21 reaches the threshold, due to the effect of centrifugal force, part of the raw material adheres to the inner wall of the filter tube 21 and moves around the guide tube 31 seat in a circle, and when the raw material moves to the position of the rectangular bar 37, due to the obstruction of the rectangular bar 37 and the rectangular plate 32, the excess raw material on the inner wall of the filter tube 21 is scraped off from the inner wall of the filter tube 21, so that the raw material is more evenly spread on the inner wall of the filter tube 21. After the raw materials are spread, the operator screws the barrel cover 353 out of the opening of the storage hopper 34, and then inserts the koji pieces into the storage hopper 34. Due to the effect of their own gravity, the koji pieces slide along the inner hole wall of the grinding top plate 351 and the top inclined surface of the grinding bottom plate 352, and slide into the gap between the grinding top plate 351 and the grinding bottom plate 352. Finally, the barrel cover 353 is screwed back into the opening of the storage hopper 34 to close the opening of the storage hopper 34, and the koji feeding operation is completed. After the feeding operation of the wine koji is completed, the air pump 361 is started to continuously extract the gas in the exhaust pipe 363 and inject it into the storage hopper 34. The gas injected into the storage hopper 34 passes through the inner hole of the grinding top plate 351, the gap between the grinding top plate 351 and the grinding bottom plate 352, and the conduit 31 in sequence, and passes through the rectangular groove 33 to blow on the raw material on the inner wall of the filter tube 21. It should be noted that the heat dissipation treatment of the raw material can be completed according to the blowing of the above-mentioned airflow on the raw material; A negative pressure cavity is formed in the exhaust pipe 363 due to the loss of internal gas. At this time, a large pressure difference is formed on both sides of the tube wall of the filter tube 21 on the top side of the rectangular plate 32. After the air flow blows on the raw materials, the air flow passes through the gaps between the raw materials and some filter holes of the filter tube 21 and flows into the exhaust pipe 363 to replenish the lost gas in the exhaust pipe 363, so as to provide gas for the air pump 361 to extract gas. When the airflow passes through the storage hopper 34, a thrust can be applied to the koji fragments to push the koji fragments toward the gap between the grinding top plate 351 and the grinding bottom plate 352. When the airflow flows into the conduit 31 from the opening at the bottom end of the storage hopper 34, the airflow blows on the impeller 356 and simultaneously applies a thrust to the grinding bottom plate 352, so that the grinding bottom plate 352 rotates slowly and cooperates with the grinding top plate 351 to grind the koji fragments into koji powder. , and due to the entrainment of the air flow, the koji powder is blown onto the raw materials at the corresponding position on the inner wall of the filter tube 21 along with the air flow, and then when the koji powder contacts the raw materials, the koji powder adheres to the surface of the raw materials, and at the same time, as the filter tube 21 rotates, the koji is evenly sprinkled on the raw materials on the inner wall of the filter tube 21. After the koji bulking operation is completed, the motor 221 reduces the rotation speed of the filter tube 21. At this time, due to insufficient centrifugal force, the raw materials at the bottom of the filter tube 21 are turned over, and the koji powder and the raw materials are fully mixed; When the raw materials are turned over in the filter tube 21, due to the obstruction of the connecting plate 234, part of the raw materials inside the raw materials are pushed out from the raw materials, so as to avoid that part of the raw materials inside the raw materials are always inside the raw materials, thereby causing part of the raw materials inside the raw materials to be unable to be fully mixed with the koji powder; It should be noted that, during the process of spreading the koji powder, the operation of the air pump 361 can be stopped intermittently and the raw materials can be turned over and mixed, and then the raw material spreading operation and the koji powder spreading operation can be restarted. Finally, the koji powder can be spread more evenly through multiple batches of koji spreading, thereby enhancing the mixing effect of the koji powder and the raw materials. After the koji and the raw materials are mixed into fermented grains, the device is stopped, and then the cover 231 is removed from the storage tube 1, and the cover 231 is pulled away from the storage tube 1. At this time, due to the pulling of the scraper 233 by the connecting plate 234, the scraper 233 moves with the cover 231, scrapes the inner wall of the bottom of the filter tube 21, and pushes the fermented grains out of the opening of the storage tube 1, completing the unloading process of the fermented grains in the device; It should be noted that after the unloading process of the device is completed, the operator starts the motor 221 to drive the filter tube 21 to rotate slowly, then unscrews the soft tube 362 from the joint 354, and connects the drainage end of the external water injection device or the water injection pipe to the joint 354, and continuously injects water into the storage hopper 34 through the external water injection device. The water flows out from the rectangular groove 33 and impacts the inner wall of the filter tube 21 in turn, thereby completing the flushing of the filter tube 21, and the flushed waste water is stored at the bottom of the storage tube 1. After the water stored in the storage tube 1 reaches the corresponding amount, the motor 221 drives the filter tube 21 to rotate rapidly, and the rotating filter tube 21 can stir the water in the storage tube 1 to flush the inner wall of the storage tube 1 and the starting components in the storage tube 1. Finally, the operator unscrews the waterproof bolt from the wall of the storage tube 1, and the waste water is directly discharged from the hole at the bottom of the storage tube 1.
