Detailed Implementation

[0029] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.

[0030] like Figure 1 and 4 As shown, the continuous steaming equipment for brewing provided in this application includes a primary steamer 1, a grain steaming machine 2, and a secondary steamer 3 arranged sequentially from top to bottom. The material in the primary steamer 1 is conveyed along a first direction; the feed end of the grain steaming machine 2 is connected to the discharge end of the primary steamer 1, and the material inside it is conveyed along a second direction, with the first and second directions being opposite. A grain-water separation mechanism is provided inside the secondary steamer 3 near its discharge end; the feed end of the secondary steamer 3 is connected to the discharge end of the grain steaming machine 2, and the material inside it is conveyed along the first direction.

[0031] Both the primary steamer 1 and the secondary steamer 3 are equipped with steam pipes 11 at the bottom for introducing steam, and exhaust pipes 12 at the top. Within the enclosed spaces of the primary steamer 1 and the secondary steamer 3, the grain is cooked by the pressure and temperature of the steam. To better control the degree of cooking and process parameters, temperature and pressure sensors are installed on the primary steamer 1 and the secondary steamer 3 for feedback. By controlling the steam flow rate introduced through the steam pipes 11 and the exhaust pipes 12, the cooking environment is dynamically adjusted.

[0032] To ensure the sealing of the inlet and outlet ends of the primary steamer 1 and the secondary steamer 3, such as Figure 4 As shown, sealed conveying mechanisms 4 are provided at both the inlet and outlet ends of the primary steamer 1 and the secondary steamer 3. Figure 3As shown, the sealed material conveying mechanism 4 includes a transition chamber 41, a buffer chamber 42 and a discharge chamber 43. A first gate 44 is provided between the transition chamber 41 and the buffer chamber 42, and a second gate 45 is provided between the buffer chamber 42 and the discharge chamber 43.

[0033] like Figure 3 As shown, the sealed conveying mechanism 4 located at the feeding end of the primary steamer 1 and the secondary steamer 3 is provided with a connecting pipe 46 between its discharge bin 43 and buffer bin 42. A first valve 461 is provided on the connecting pipe 46. The buffer bin 42 is also provided with a drain pipe 47, and a second valve 471 is provided on the drain pipe 47.

[0034] like Figure 3 As shown, the sealed conveying mechanism 4 located at the inlet end of the primary steamer 1 and the secondary steamer 3 has a discharge bin 43 connected to the inner cavity of the primary steamer 1 and the secondary steamer 3, and a transition bin 41 receiving and temporarily storing external materials. The sealed conveying mechanism 4 located at the outlet end of the primary steamer 1 and the secondary steamer 3 has a transition bin 41 connected to the inner cavity of the primary steamer 1 and the secondary steamer 3 respectively, used to receive and temporarily store materials processed by the primary steamer 1 and the secondary steamer 3. Because steam is introduced into the primary steamer 1 and the secondary steamer 3 through the steam pipe 11, the primary steamer 1 and the secondary steamer 3 have a high temperature and high pressure environment, resulting in inconsistent pressure at both ends of the sealed conveying mechanism 4. Therefore, when feeding material into the primary steamer 1 from the inlet end, the second gate 45 is kept closed first, and the first gate 44 is opened so that the material in the transition bin 41 can fall into the buffer bin 42. After the buffer bin 42 is filled with material, the first gate 44 is closed. Then, open the first valve 461 while keeping the second valve 471 closed to ensure that the air pressure in the buffer chamber 42 is consistent with the pressure inside the primary steamer 1. Then, open the second gate 45 to allow the material to fall smoothly into the primary steamer 1. After the material has fallen, close the second gate 45, close the first valve 461, and open the second valve 471 to release the pressure in the buffer chamber 42 and make it consistent with the outside pressure. At this point, open the first gate 44 to allow the material to smoothly fill the buffer chamber 42 from the transition chamber 41. Then, close the first gate 44 and the second valve 471, and open the first valve 461 to ensure that the air pressure in the buffer chamber 42 is consistent with the pressure inside the primary steamer 1. Then, open the second gate 45 to allow the material to fall back into the primary steamer 1. This cycle repeats, ensuring that the pressure inside the primary steamer 1 is maintained while the material is smoothly fed into the primary steamer 1.

[0035] Material falling into the primary steamer 1 is conveyed forward in the first direction under high temperature and high pressure. During the conveying process, it is steamed. When the material is conveyed to the discharge end of the primary steamer 1, the primary steaming process is completed. The material is received and temporarily stored in the transition chamber 41 of the sealed conveying mechanism 4 at the discharge end. When discharging, the first gate 44 of the sealed conveying mechanism 4 is opened first, while the second gate 45 remains closed. The primary steamed material is then filled into the buffer chamber 42. Then, the first gate 44 is closed and the second gate 45 is opened, and the material in the buffer chamber 42 can be smoothly discharged and received by the inlet end of the grain steamer 2. This cycle is repeated to achieve smooth discharge while maintaining the pressure inside the primary steamer 1. If the pressure inside the primary steamer 1 is too high during the primary steaming process, the exhaust pipe 12 is opened until the pressure is within the set range.

[0036] The material enters the grain steamer 2 through the feed end, and water is added simultaneously. The grain steamer 2 then performs the steaming operation while conveying the material. The grain steamer 2 conveys the material in a second direction opposite to the first direction, thus not only making full use of the vertical space of the production line but also shortening the overall length of the production line. Grain and water are simultaneously conveyed towards the discharge end of the grain steamer 2, where solid-liquid separation occurs at the grain-water separation mechanism near the discharge end. The grain then enters the re-steamer 3 through the discharge end of the grain steamer 2. The operation of the sealed conveying mechanism 4 at the feed end and the sealed conveying mechanism 4 at the discharge end of the re-steamer 3 is the same as that of the primary steamer 1, and will not be described again.

[0037] Specifically, to facilitate the conveying of materials within the primary steamer 1 and the secondary steamer 3, in some embodiments, such as Figure 4 As shown, both the primary steamer 1 and the secondary steamer 3 include a housing 14 and a plate chain conveyor 13 disposed within the housing 14, as... Figure 5As shown, the housing 14 has baffles 17 and scrapers 15 extending along the width of the plate chain conveyor 13 on both sides of the feed end. In the conveying direction, the scraper 15 is located at the front end of the baffle 17. After the material enters the primary steamer 1 or the secondary steamer 3 from the feed end, it is received by the plate chain conveyor 13 and conveyed to the discharge end by the plate chain conveyor 13. When the material reaches the chain plate of the plate chain conveyor 13, it is in a piled state with uneven thickness. When it reaches the scraper 15, the higher parts of the material are scraped down and flattened by the scraper 15. Thus, the piled material is flattened under the action of the scraper 15, and the thickness of the material on the chain plate is basically consistent, thereby ensuring the consistency of the primary / secondary steaming of the material. Meanwhile, when the material falls from the feed end of the primary steamer 1 / secondary steamer 3 to the plate chain conveyor 13, the material may rebound, causing the material to fall outside the end of the plate chain conveyor 13, resulting in material waste. The baffle 17 can effectively block the rebounding material and prevent the material from rebounding to the outside of the plate chain conveyor 13 in the opposite direction of the conveying direction, effectively reducing material waste. At the same time, the baffle 17 can also scrape the material adhering to the plate chain conveyor 13, keeping the plate chain conveyor 13 clean.

[0038] Furthermore, such as Figure 5 As shown, in order to prevent the material from detaching from the plate chain conveyor 13 during the conveying process in the primary steamer 1 and the secondary steamer 3, baffle plates 18 are also provided on both sides of the plate chain conveyor 13, and the baffle plates 18 extend along the length direction of the plate chain conveyor 13.

[0039] In some embodiments, such as Figure 1 and 2 As shown, both the primary steamer 1 and the secondary steamer 3 are equipped with two sets of sealed conveying mechanisms 4 distributed along the width direction of the plate chain conveyor 13 at both the inlet and outlet ends. The simultaneous feeding of the two sets of sealed conveying mechanisms 4 at the inlet end allows the material to be distributed as evenly as possible along the width direction of the chain plates of the plate chain conveyor 13, preventing material from being distributed in the middle or on one side of the chain plates, thus improving the utilization rate of the plate chain conveyor 13 and the leveling effect of the material. To ensure sufficient space above the housing 14 of the primary steamer 1 and the secondary steamer 3 for installing the two sealed conveying mechanisms 4, as shown... Figure 1 As shown, the cross-section of the housing 14 can be set as an elliptical structure with its minor axis pointing in the height direction. Compared with the circular structure of the housing 14, the top of the elliptical structure housing 14 has a gentler arc surface as the mounting surface for the two sealed conveying mechanisms 4, which is convenient for installation, and the height is lower, saving space, while accommodating a wider plate chain conveyor 13.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, to facilitate automatic cleaning of the primary steamer 1 and the secondary steamer 3, multiple cleaning pipes 161 are provided above the primary steamer 1 and the secondary steamer 3 along their length. One end of each cleaning pipe 161 is connected to a nozzle 162. A main cleaning pipe 16 connecting the multiple cleaning pipes 161 is provided outside the primary steamer 1 and the secondary steamer 3. A drain pipe 163 is provided at the bottom of the primary steamer 1 and the secondary steamer 3. When the primary steamer 1 and the secondary steamer 3 need cleaning, water is introduced into the cleaning pipes 161 through the main cleaning pipe 16. The water is sprayed out by the nozzles 162, which are rotating nozzles, to clean the inner walls of the primary steamer 1 and the secondary steamer 3 and the plate chain conveyor 13. The wastewater after cleaning falls to the bottom of the primary steamer 1 and the secondary steamer 3 and is collected and discharged by the drain pipe 163.

[0041] like Figure 1 , 4 As shown in Figure 6, specifically, the grain steaming machine 2 includes a cylindrical tank 21, spiral blades 22 fixed inside the tank 21, and a drive seat 211 for driving the tank 21 to rotate. The inlet end of the tank 21 is provided with an inlet pipe 23 that connects to the outlet end of the primary steamer 1. The inlet pipe 23 is rotatably connected to the tank 21. The other end of the tank 21 is provided with multiple sieve plates 24 arranged circumferentially to form the grain-water separation mechanism. The inlet of the inlet pipe 23 is located below the discharge bin 43 of the sealed conveying mechanism 4 at the outlet end of the primary steamer 1, thus receiving the material after primary steaming and feeding it into the grain steaming machine 2. After the material is introduced into the rotating tank 21 of the grain steaming machine 2 from the inlet end, it is conveyed forward under the action of the spiral blades 22. The liquid level is below the height of the spiral blades 22. While the grain is conveyed forward, it is agitated along with the water inside, performing the grain steaming operation. When the material is conveyed to the screen plate 24 near the discharge end, the moisture leaks out through the screen plate 24, and the grain material continues to be conveyed to the discharge end for grain-water separation. This simplifies the grain-water separation process and equipment, and greatly improves efficiency.

[0042] like Figure 6As shown, further, to facilitate the feeding and grain-water separation operation of the grain steaming machine 2, the grain steaming machine 2 also includes a fixed shell 25. The end of the tank body 21 away from the feed pipe 23 is an open end. The fixed shell 25 is open at one end and closed at the other. The open end of the tank body 21 extends from the opening of the fixed shell 25 into the interior of the fixed shell 25 and has a gap with the closed end of the fixed shell 25. A material discharge port 251 is provided at the bottom of the fixed shell 25 at this gap. The sieve plate 24 is located inside the fixed shell 25. A water collection funnel 252 is provided at the bottom of the fixed shell 25 corresponding to the position of the sieve plate 24. The open end of the fixed shell 25 has a flange extending towards the tank body 21. The open end of the tank 21 of the grain steaming machine 2 extends into the fixed shell 25, and the screen plate 24 on the tank 21 is located inside the fixed shell 25. The water that leaks down from the screen plate 24 is collected by the fixed shell 25 and discharged through the water collection funnel 252, while the grain material is discharged directly from the open end of the tank 21 and directly discharged through the discharge port 251, thus achieving effective separation of grain and water. In addition, the flange set on the fixed shell 25 prevents the water accumulated inside the fixed shell 25 from flowing out. At the same time, in order to prevent the water inside the fixed shell 25 from being discharged through the discharge port 251, one end of the discharge port 251 can be extended to a certain height inside the fixed shell 25.

[0043] To ensure the effective separation of grain and water in the sieve plate 24, such as Figure 6 As shown, in some embodiments, a blower 26 is also provided above the fixed shell 25, and an air distribution pipe 27 is provided along its length on the upper inner wall of the fixed shell 25. The air distribution pipe 27 corresponds to the position of the sieve plate 24, and the outlet of the blower 26 is connected to the air distribution pipe 27 through a pipe. An induced draft fan 28 is also provided on the fixed shell 25. The inlet of the induced draft fan 28 is connected to the inner cavity of the fixed shell 25, and the outlet of the induced draft fan 28 is connected to the outside. The blower 26 and the air distribution pipe 27 can blow towards the sieve plate 24 at its bottom, thereby blowing out the material trapped in the mesh of the sieve plate 24 and preventing the material remaining in the mesh of the sieve plate 24 from affecting the grain-water separation effect of the sieve plate 24. The induced draft fan 28 can be used to discharge the exhaust gas generated during the grain cooking process.

[0044] like Figure 1 As shown, in some embodiments, a conveying mechanism 29 is provided at the bottom of the discharge port 251. The outlet end of the conveying mechanism 29 is connected to the inlet end of the re-steamer 3, and the bottom of the conveying mechanism 29 has a water receiving trough. The material processed by the grain steamer 2 falls from the discharge port 251 onto the conveying mechanism 29, and is conveyed by the conveying mechanism 29 to the inlet end of the re-steamer 3. The material discharged from the grain steamer 2 may have a lot of residual moisture, and the water receiving trough at the bottom of the conveying mechanism 29 can catch the water dripping from the material.

[0045] like Figure 1 and 2As shown, to further improve space utilization, there are two of each of the pre-steamer 1, the grain steaming machine 2, and the re-steamer 3, and these three machines correspond one-to-one. Figure 1 and 4 As shown, a primary steamer 1, a grain steaming machine 2, and a secondary steamer 3 form a group, for a total of two groups. Two primary steamers 1 are installed in parallel on the top layer of the platform, two grain steaming machines 2 are installed in parallel on the middle layer of the platform, and two secondary steamers 3 are installed on the bottom layer of the platform.

[0046] like Figure 1 and 2 As shown, a single conveying mechanism is used to simultaneously supply materials to the inlet ends of two primary steamers 1, thereby reducing the number of devices. The conveying mechanism includes a main conveying mechanism 51 located between and parallel to the two primary steamers 1, and two auxiliary conveying mechanisms 52 corresponding one-to-one with the two primary steamers 1. The conveying direction of the auxiliary conveying mechanisms 52 is perpendicular to the first direction. To enable one main conveying mechanism 51 to simultaneously supply materials to the two auxiliary conveying mechanisms 52, one end of the main conveying mechanism 51 is provided with a discharge cylinder facing each of the two auxiliary conveying mechanisms 52.

[0047] In the embodiment described above, where a primary steamer 1 has two sealed feeding mechanisms 4 arranged along its width direction, by providing a feeding cylinder at one end of the secondary feeding mechanism 52 that faces the transition chambers 41 of the two sealed feeding mechanisms 4 respectively, one secondary feeding mechanism 52 can simultaneously feed materials to the transition chambers 41 of the two sealed feeding mechanisms 4 of the primary steamer 1.

[0048] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
