Description

Technical Field

[0001] The utility model relates to the technical field of bran steaming equipment, in particular to a multi-layer continuous unloading bran steaming machine. Background Art

[0002] Rice husk is an important additive in the process of liquor brewing. For example, it needs to be added in the saccharification and culture, fermentation, and distillation. In the process of saccharification and culture of Xiaoqu Qingxiang dregs, it is usually necessary to lay a layer of rice husk on the lower layer of the saccharification material and cover the upper layer of the saccharification material with a layer of rice husk. Laying rice husk can effectively prevent the saccharification material from sticking to the mesh plate, and covering rice husk can play a good role in heat preservation of the saccharification material. However, raw rice husk cannot be used directly in the brewing process. It usually needs to be processed by high-temperature steaming to mature the rice husk before it can be used as a brewing auxiliary material.

[0003] There are two main processes for rice husk cooking: continuous production and discontinuous production. The former has high output and high production efficiency, and the main equipment is steel belt and chain plate rice husk steamers; the latter has low output and low production efficiency, and is usually steamed in a wine retort with water in the bottom pot, or steamed with steam in a tank truck, and some use a cooking tower rice husk steamer, which is shaped like a silo. Due to structural limitations, it cannot be produced continuously, and is generally fed and discharged intermittently.

[0004] In order to improve the rice husk processing capacity, more and more wineries are using steel belt and chain plate type bran steamers, whose main structures are similar, mainly divided into two parts: cooking section and cooling section. The cooking section is composed of a set of rotating chain plates or roller driven steel belts, cooking section frame, feed hopper, tunnel box, cooking chamber, steam pipeline components, drainage pipeline components, etc. The cooling section is composed of a set of rotating chain plates or roller driven steel belts, cooling section frame, air outlet top cover, tunnel box, cooling chamber, discharge hopper, etc. In order to fully cook or cool the rice husks in the tunnel box, the chain plates or steel belts carrying the rice husks must be perforated.

[0005] However, in the actual production process, rice husk fragments, chaff, etc. on the steel belt or chain plate will fall into the cooking chamber and the cooling chamber through the mesh holes; if there is too much rice husk accumulation in the cooking chamber or it has been there for a long time, it will become moldy and carbonized, making it difficult to clean. One of the purposes of steaming rice husks is to remove the unpleasant smell in the rice husks. Therefore, if the rice husks in the cooking chamber become moldy, the moldy smell will be transmitted to the rice husks in the tunnel box above the mesh belt through steam, which will reduce the quality of the steamed rice husks; and if there is too much rice husk accumulation in the cooling chamber, it will affect the air supply surface and cooling effect of the centrifugal fan in the cooling chamber, resulting in prolonged dehumidification and cooling time of the finished rice husks, affecting the yield; therefore, the fallen rice husks need to be cleaned up in time.

[0006] At present, the falling materials in the cooking room and cooling room are cleaned manually by workers on site, with a speed of 25m 3Taking the tunnel - type rice bran steaming machine with an hourly output of [h] as an example, under normal production conditions, the material falling in the steaming chamber of each steaming machine needs to be cleaned 1 - 2 times per month, and the material falling in the cooling chamber needs to be cleaned 1 - 2 times per week. If there are multiple steaming machines in production, the number of cleaning times will increase exponentially. Currently, the cleaning is all done manually by operators. They need to use tools such as cleaning rakes, shovels, and brooms to clean out the rice husk material. During cleaning, they need to bend down and lower their heads, and there is dust flying everywhere. The entire cleaning process has a high labor intensity, a relatively poor working environment, extremely high labor costs, and the production line also needs to be shut down, thus reducing production efficiency.

[0065] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0066] Embodiment:

[0067] As Figures 1 to 6 shown, the embodiment of the present application discloses a multi-layer continuous discharging rice husk steamer, which can carry out continuous production, has the advantages of large output and high production efficiency, and does not stick to materials or leak materials, so it does not need to be cleaned regularly. Its specific structure includes: a feeding device 1, a bin top cover 2, an exhaust pipe 3, a bin housing 4, a temporary storage hopper 5 and a multi-layer steaming layer 6.

[0068] The feeding device 1 has a plurality of discharge ports 11, and a feeding valve 12 is installed on each discharge port 11; the feeding device 1 is preferably a feeding scraper conveyor, or can also be a screw conveyor, or other similar feeding mechanisms, which belong to the prior art, so the specific structure will not be described in detail; the plurality of discharge ports 11 are arranged on the bottom surface and are arranged side by side at intervals to improve the conveying effect and avoid material jamming.

[0069] The bin top cover 2 includes a plurality of horizontally arranged and side-by-side falling cylinders 21, and the falling cylinders 21 correspond to and communicate with the discharge ports 11 one by one; the falling cylinders 21 are vertically through, and the shape and size of the top opening match those of the discharge ports 11 and are docked through flanges, ensuring the feeding effect.

[0070] The exhaust pipe 3 is arranged above the bin top cover 2 and is connected to a plurality of falling cylinders 21 for discharging steam.

[0071] The bin housing 4 is provided at the bottom of the bin top cover 2; the bin housing 4 is vertically through, and the shape and size of the top opening match those of the bin top cover 2 and are connected by welding, improving the structural compactness and regularity of the device.

[0072] The temporary storage hopper 5 is provided at the bottom of the bin housing 4; the shape and size of the top opening of the temporary storage hopper 5 match those of the top opening of the bin housing 4 and are connected by welding, improving the structural compactness and regularity of the device; its inner cavity gradually shrinks from top to bottom and has an opening at the bottom for smoothly converging the cooked rice husks and avoiding material accumulation and jamming.

[0073] The multi-layer steaming layer 6 is arranged at intervals up and down for steaming the rice husks multiple times. In this embodiment, it is set to two layers, but not limited to this. In actual production, the corresponding number of layers can be set according to the output and steaming duration requirements, so no specific limitation is made.

[0074] Specifically, each layer of the steaming material layer 6 includes: a steam pipeline 61 and a plurality of steaming material units 62; the number of the steaming material units 62 is set to five in this embodiment, but is not limited thereto, and can be correspondingly set according to the production output requirements in actual production, so no specific limitation is made.

[0075] Among them, the steam pipeline 61 is horizontally arranged in the bin housing 4, is provided with a plurality of exhaust holes, and the inlet end penetrates out of the bin housing 4; the exhaust holes are preferably arranged on the bottom surface of the steam pipeline 61, and the downward opening helps to prevent blockage and improves the use effect. The plurality of steaming material units 62 are arranged side by side horizontally, and are located above the steam pipeline 61 and correspond to the blanking cylinders 21 one by one.

[0076] Exemplarily, each steaming material unit 62 includes: a steaming bin 62a, a plurality of turning plates 621 and a turning driving mechanism 622; the turning plates 621 adopt a multi-plate parallel structure, which avoids the too large turning radius and space occupation required when using a single turning plate, thereby increasing the emptying rate of the rice husks. The number of the turning plates 621 is set to three in this embodiment, but is not limited thereto, and can also be more, and no specific limitation is made.

[0077] Among them, the steaming bin 62a is located in the bin housing 4; the plurality of turning plates 621 are arranged side by side horizontally, are installed in the bin housing 4, and are arranged below the steaming bin 62a, and can rotate reciprocally, so that the rice husks in the steaming bin 62a can fall into the corresponding steaming material units 62 of the next layer of the steaming material layer 6; a plurality of steam through holes 6211 are opened on the turning plates 621 for enabling steam to pass through the turning plates 621 to steam the rice husks in the steaming bin 62a.

[0078] The turning driving mechanism 622 is arranged outside the bin housing 4 and is in transmission connection with the plurality of turning plates 621 for driving the turning plates 621 to rotate reciprocally.

[0079] The main operation process of the above technical solution is as follows:

[0080] The upstream feeding equipment conveys the rice husks to the feeding device 1, and the feeding device 1 then sequentially feeds the rice husks into the topmost steaming material layer 6. Specifically: when feeding the first steaming material unit 62, the first feeding valve 12 corresponding to directly above it is opened (other valves are in the closed state), so the material sequentially passes through the first discharge port 11 and the first blanking cylinder 21 and falls into the first steaming bin 62a. Since the first group of turning plates 621 are in a horizontal posture, the rice husks gradually accumulate in the first steaming bin 62a. When the rice husk layer in the steaming bin 62a reaches the height requirement, the corresponding first feeding valve 12 is closed, and at the same time the second feeding valve 12 is opened to start feeding the second steaming material unit 62, and so on to complete the feeding work of the rice husks in the topmost steaming material layer 6 one by one.

[0081] Preferably, a high-level sensor is installed above each cooking bin 62a in the topmost steaming material layer 6, which is used to feedback signals to determine whether the rice husk material layer in the cooking bin 62a reaches the set height, so as to close the corresponding feed valve 12 accordingly, thus realizing automated operation and improving production efficiency.

[0082] In the topmost steaming material layer 6, when the first steaming unit 62 is feeding, the steam pipeline 61 of this layer starts to input steam, and the rice husk cooking process starts immediately; when the last steaming unit 62 is feeding, the flipping drive mechanism 622 in the first steaming unit 62 drives the flipping plate 621 to rotate to an inclined posture, so that the preliminarily steamed rice husks in the first cooking bin 62a fall into the first steaming unit 62 in the second steaming material layer 6, and at the same time, the steaming units 62 of this layer start to input steam, enabling the second layer to start re-steaming; and so on, so that the rice husks are cooked layer by layer in multiple steaming material layers 6 from top to bottom.

[0083] Preferably, a solenoid valve is installed at the inlet end of the steam pipeline 61, so as to control whether steam is introduced into the steam pipeline 61, which realizes automated operation and improves production efficiency.

[0084] It should be noted that the rice husks in the cooking bin 62a follow the principle of first in, first out. That is, in the topmost steaming material layer 6, when the last steaming unit 62 finishes feeding, the first steaming unit 62 just finishes discharging, and then the first steaming unit 62 starts re-feeding immediately, while the second steaming unit 62 starts discharging. Such a cycle can carry out a continuous production process of feeding and discharging at the same time, and the other steaming material layers 6 follow the same pattern.

[0085] First of all, by setting multiple steaming material layers 6, the present utility model can cook the rice husks multiple times and control the residence time of the rice husks in each cooking bin 62a, so that they start to be discharged before they are prone to arching due to stacking and compaction and steam cooking, thereby improving the product quality and realizing the continuous production of the vertical rice bran steamer, thus expanding the output and improving the production efficiency.

[0086] Secondly, the present utility model has a fully enclosed structure, enabling the cooked rice husks to be directly output to downstream equipment, thus avoiding the problems of sticking and leaking materials of chain plate and steel belt type rice bran steamers, making the production environment clean and tidy, eliminating the need for regular manual cleaning and shutting down the production line, reducing the labor cost, and improving the production efficiency.

[0087] Finally, the utility model can realize the online unmanned production of the bran steamer in conjunction with other sensors and video monitoring equipment. The operator can control the operation of the bran steamer in the central control room. For example, the material level information on the cooking bin 62a, the steam pressure information on the steam pipeline 61, the valve switch signal, the opening and closing signal of the flip plate 621, etc. are all displayed on the control screen. This greatly improves the working environment of the front-line production personnel, and there is no need to endure the noise pollution, dust pollution, etc. in the traditional bran steaming production process for a long time.

[0088] In some embodiments, Figures 2 to 4 As shown, it also includes: multiple water collecting grooves 7 and drainage pipes 8; wherein the multiple water collecting grooves 7 are annular in structure and are arranged one by one in the blanking barrel 21; the drainage pipe 8 is arranged on the outside of the silo top cover 2 and is connected to the multiple water collecting grooves 7.

[0089] Specifically, the water collecting trough 7 is preferably arranged at the lower edge of the blanking barrel 21. When in use, the condensed water on the blanking barrel 21 enters the water collecting trough 7 along the inner surface and is then led away through the drain pipe 8, preventing the steam condensed water from dripping into the rice husk, thereby improving the cooking effect.

[0090] In some embodiments, Figure 1 As shown, it also includes: a plurality of legs 9 and a discharge device 10.

[0091] A plurality of legs 9 are installed on the outer periphery of the temporary storage cone 5; specifically, a frame is provided outside the connection area between the temporary storage cone 5 and the silo shell 4, and the legs 9 are installed at the bottom of the frame. The number is set to four, but it can also be three or more, without specific limitation; it plays a role of stable support to ensure the stable operation of the equipment.

[0092] The discharging device 10 is installed at the bottom outlet of the temporary storage cone hopper 5; it is used to transport the rice husks falling into the temporary storage cone hopper 5 to the downstream equipment for cooling and then transport them to the finished rice husk bin for storage. It is preferably a multi-joint auger rice husk discharging machine, which is connected to the temporary storage cone hopper 5 through a flange, which is convenient for disassembly and maintenance and the connection is tight and tight, which can effectively prevent rice husk leakage, steam leakage, water leakage and the like during the production process.

[0093] In some embodiments, Figures 1 to 2 As shown, both ends of the flip plate 621 are provided with a rotating shaft 6212, one rotating shaft 6212 is installed with a bearing seat 623 after passing through the silo shell 4 horizontally, and the bearing seat 623 is installed outside the silo shell 4, and the other rotating shaft 6212 is connected to the flip driving mechanism 622 after passing through the silo shell 4 horizontally.

[0094] Exemplarily, the flip plate 621 is formed by welding a grille support and a sieve plate with steam holes 6211, which not only ensures structural stability and load-bearing capacity, but also reduces the overall weight.

[0095] Through the above settings, the load-bearing capacity and structural stability of the flipping plate 621 are significantly improved, the flipping smoothness is ensured, and the use effect is enhanced.

[0096] Based on the above embodiments, as Figure 1 shown, the flipping drive mechanism 622 includes: a first connecting rod 6221, a plurality of second connecting rods 6222, a drive cylinder 6223, and a push-pull rod 6224.

[0097] Among them, the first connecting rod 6221 is arranged horizontally and is perpendicular to a plurality of rotating shafts 6212; the plurality of second connecting rods 6222 are arranged side by side at intervals, and one end of each is hinged to the first connecting rod 6221, and the other end is connected to the plurality of rotating shafts 6212 in one-to-one correspondence; the drive cylinder 6223 is installed outside the silo housing 4; the push-pull rod 6224 has one end hinged to the drive end of the drive cylinder 6223 and the other end hinged to the first connecting rod 6221.

[0098] During operation, the drive end of the drive cylinder 6223 drives the push-pull rod 6224 to move, the push-pull rod 6224 pulls the first connecting rod 6221 to move, and the first connecting rod 6221 drives a plurality of rotating shafts 6212 to rotate through a plurality of second connecting rods 6222, thereby driving a plurality of flipping plates 621 to perform flipping motion to achieve opening or closing.

[0099] Through the above design of the flipping drive mechanism 622, it is possible to stably and smoothly drive a plurality of flipping plates 621 to perform flipping motion synchronously. Its structure is stable and it is convenient for installation and layout.

[0100] In some embodiments, as Figure 6 shown, a cover plate 6213 is provided on one side of the top surface of the flipping plate 621. The cover plate 6213 is used to cover the gap between two adjacent flipping plates 621, thereby improving the load-bearing capacity and ensuring the steaming effect.

[0101] In some embodiments, as Figure 1 , Figure 3 and Figure 4 shown, the inner cavity of the blanking cylinder 21 gradually expands from top to bottom, specifically in a regular quadrangular pyramid structure.

[0102] The exhaust pipe 3 includes: a main exhaust pipe 31 and a plurality of branch exhaust pipes 32; among them, the main exhaust pipe 31 is arranged horizontally; the plurality of branch exhaust pipes 32 are arranged side by side and vertically at intervals, and the top ends are communicated with the main exhaust pipe 31, and the bottom ends are communicated with the plurality of blanking cylinders 21 in one-to-one correspondence.

[0103] Preferably, a steam discharge fan is installed on the main exhaust pipe 31 for performing a suction operation on the inside of the main exhaust pipe 31, which can significantly improve the exhaust effect.

[0104] Through the above settings, it is possible to prevent materials from falling into the exhaust pipe 3 and improve the use effect of the device.

[0105] In some embodiments, as Figure 4 shown, the steam pipeline 61 has a rich-shaped structure, including: a main steam pipe 611 and multiple branch steam pipes 612; wherein, the main steam pipe 611 is horizontally arranged, and the inlet end penetrates out to the outside of the bin housing 4; the multiple branch steam pipes 612 are horizontally arranged side by side at intervals on both sides of the main steam pipe 611.

[0106] Specifically, the ends of the main steam pipe 611 and / or the multiple branch steam pipes 612 are fixedly connected to the inner wall of the bin housing 4, so as to play a supporting role, thereby improving the installation stability and structural strength of the steam pipeline 61.

[0107] Through the above structural design of the steam pipeline 61, steam can be evenly transported to each cooking bin 62a, thereby improving the cooking effect and ensuring the product quality.
