Description

Technical Field

[0001] This invention relates to the field of brewing equipment technology, and in particular to an integrated machine for multi-round solid-state fermentation with layered old mash discharge and new mash input. Background Technology

[0002] Currently, in the solid-state fermentation brewing industry, the operation of loading and unloading the mash in the fermentation pit is a key link in the production process. Traditionally, this is mainly done manually or with simple mechanical auxiliary equipment. When operating manually, workers need to enter the fermentation pit and use tools such as shovels to dig out and transport the fermented mash layer by layer, and then lay the new material into the fermentation pit layer by layer. Some companies use independently operated discharge and feeding machines to operate separately, such as using screw conveyors or grab bucket equipment to dig and transport the mash. However, these devices are usually single-function, and the discharge and feeding need to be carried out in steps. Moreover, the movement and positioning of the equipment rely on manual assistance. However, existing technologies and equipment have certain shortcomings: First, manual unloading is extremely labor-intensive, and the working environment is hot and humid, which is not only inefficient, but also easily damages the layered structure of the mash, affecting the quality of subsequent fermentation. Secondly, the existing simple mechanical discharge method lacks the ability to accurately extract the mash in layers, which easily leads to the mixing of new and old mash. In addition, after discharge, it is necessary to call in the feeding equipment to lay the new material, which results in frequent equipment switching, large space occupation, and poor operation continuity. To address the aforementioned issues, this invention proposes an integrated machine for multi-stage solid-state fermentation, involving the discharge of old mash and the introduction of new mash into the fermentation pit. Summary of the Invention

[0003] This invention provides an integrated machine for multi-round solid-state fermentation, which separates old mash for discharging and new mash for feeding, solving the problems of existing discharging and feeding equipment, poor stratification accuracy, and low operating efficiency.

[0004] This invention provides the following technical solution: A multi-round solid-state fermentation integrated machine for discharging old mash and feeding new mash into a fermentation pit includes a base frame installed at the top opening of the fermentation pit. Multiple foot plates are symmetrically fixed to the bottom of the base frame. Two movable frames are symmetrically slidably connected to the base frame. A common gantry frame is installed on the top of the two movable frames, and a lifting component is connected to the gantry frame. The integrated machine also includes: The material receiving component installed on one side of the lifting component is able to dig out the fermented mash layer by layer, and to separate and dig out the mash in the fermentation pit. The material spreading component, installed on the other side of the lifting component, is used to spread the fermented mash layer by layer in the cellar.

[0005] In one possible design, the lifting components are respectively fixedly installed on the mounting brackets on the top of both sides of the gantry frame. The top of the mounting bracket is fixedly installed with an electric push rod, and also includes an adjustment plate slidably connected to the gantry frame. The output shafts of the two electric push rods are fixedly connected to the top of the adjustment plate. Two mounting rods are symmetrically fixedly installed at the bottom of the adjustment plate. The bottom ends of the two mounting rods are fixedly installed with the same support plate. The material receiving component and the material spreading component are respectively installed on both sides of the support plate.

[0006] In one possible design, two slide rails are symmetrically fixedly installed on both sides of the gantry frame, and four sliding holes are symmetrically opened on the adjustment plate. The slide rails pass through the corresponding sliding holes and are slidably connected to the inner wall of the sliding holes.

[0007] In one possible design, the receiving component includes a first mounting box fixedly installed on one side of a support plate. A feeder is installed inside the first mounting box, with one end of the feeder extending to the outside of the first mounting box. A first drive motor is fixedly installed on one side of the first mounting box. The output shaft of the first drive motor extends into the first mounting box and is fixedly installed with a drive shaft. A conveying roller is fixedly sleeved on the drive shaft. Multiple scrapers are integrally and equally spaced on the outer circumferential side of the conveying roller. One end of the drive shaft extends to the outside of the first mounting box. The same transmission assembly is installed on the drive shaft and the feeder. The transmission assembly is located outside the first mounting box. The component also includes a first particle pump fixedly installed on the top of the support plate. The suction end of the first particle pump extends into the first mounting box, and the discharge end of the first particle pump is used to connect to a pipe for conveying the fermented mash.

[0008] In one possible design, the feeder includes a drive shaft rotatably connected within a first mounting box, on which two helical blades are fixedly mounted, the helical directions of the two helical blades being symmetrically arranged, the suction end of the first particle pump corresponding to the side of the two helical blades that are close to each other, and one end of the drive shaft extending to the outside of the first mounting box and connected to a transmission assembly.

[0009] In one possible design, an arc-shaped support plate located below two helical blades is fixedly installed inside the first mounting box. A baffle box is fixedly installed on the top of the arc-shaped support plate, and the top of the baffle box extends above the first mounting box. The suction end of the first particle pump extends into the baffle box and is fixedly connected to one side of the inner wall of the baffle box. A conical guide frame is fixedly installed on one side of the baffle box, and a baffle cover plate is fixedly installed on one side of the conical guide frame. One side of the baffle cover plate extends to the other side of the first mounting box and is fixedly connected to the other side of the first mounting box. An opening is provided at the bottom of the baffle cover plate.

[0010] In one possible design, the transmission assembly includes a first sprocket and a second sprocket, which are respectively fixedly mounted on a transmission shaft and a drive shaft. The first sprocket and the second sprocket are connected by the same chain. A protective cover for protecting the first sprocket, the second sprocket, and the chain is fixedly installed on the outside of the first mounting box.

[0011] In one possible design, the feeding component includes a second mounting box fixedly installed on the other side of the support plate. A conveying pipe is fixedly installed inside the second mounting box. An elongated discharge port is opened on the bottom inner wall of the conveying pipe. A second drive motor is fixedly installed on one side of the second mounting box. One end of the second drive motor extends into the conveying pipe and is fixedly installed with a conveying screw. One end of the conveying screw is rotatably connected to the inner wall of one side of the second mounting box. A second granulation pump is fixedly installed on the top side of the second mounting box. The discharge end of the second granulation pump extends into the conveying pipe and is fixedly connected to the top inner wall of the conveying pipe. The suction end of the second granulation pump is used to connect to a pipe for conveying the fermented mash.

[0012] In one possible design, a power box is fixedly mounted on one side of the base frame. Two reciprocating screws are symmetrically rotatably connected inside the base frame. A sliding plate extending into the base frame is fixedly mounted on the inner side of the movable frame. The sliding plate has through holes, and the reciprocating screws pass through the corresponding through holes. A transmission slider is fixedly mounted on the inner wall of one side of the through hole. The transmission slider cooperates with the helical groove on the reciprocating screw. A mounting shaft is fixedly mounted on one end of the reciprocating screw. One end of the mounting shaft extends into the power box and is rotatably connected to the inner wall of one side of the power box. A third drive motor is fixedly mounted on one side of the power box. One end of the third drive motor extends into the power box and is connected to a drive assembly. The drive assembly is connected to the two mounting shafts respectively.

[0013] In one possible design, the drive assembly includes a rotating shaft fixedly mounted on the output shaft of a third drive motor, on which two worm gears are fixedly sleeved, and on which a worm wheel is fixedly sleeved, with the worm gears meshing with the worm wheel.

[0014] In this invention, the entire machine is first stably installed at the top opening of the fermentation pit using a base frame and foot plates. Then, the controller starts the third drive motor, which drives two reciprocating screws to rotate synchronously. This causes the moving frame to move the gantry frame and the lifting, collecting, and spreading components mounted on it laterally to the starting end of the work area within the fermentation pit. Simultaneously, two electric push rods are activated to push the adjusting plate downwards smoothly along the slide rail, causing the collecting and spreading components on both sides of the support plate to descend synchronously to the initial working height set within the fermentation pit. When discharging the old mash, the first drive motor is activated to drive the conveyor rollers and scrapers in a circular motion, using the scrapers to... The fermented old mash in the fermentation pit is scraped and peeled off layer by layer. Guided by an arc-shaped support plate, a baffle box, a conical guide frame, and a baffle cover, the scraped mash is gathered onto two spiral blades. Simultaneously, the first drive motor, via a transmission assembly, drives the drive shaft and the two symmetrically spiraling blades to rotate, transporting the gathered old mash from both sides towards the center to the suction end of the first granular pump. The first granular pump continuously extracts the old mash through pipes and transports it outside the fermentation pit. With the scraper scraping layer by layer and the spiral blades continuously transporting the mash, combined with the lifting component lowering the receiving component one layer at a time and the moving frame moving the receiving component laterally back and forth, the mash inside the fermentation pit can be completely removed. The old mash is thoroughly cleaned and discharged layer by layer and section by section from top to bottom. After the old mash is cleaned layer by layer, the spreading component immediately performs the fermentation operation at the same height. The suction end of the second granular pump is connected to the pipeline for conveying new mash. The second granular pump is started to pump the new mash to be fermented into the conveying pipe. At the same time, the second drive motor is started to drive the conveying screw to rotate, pushing the new mash entering the conveying pipe axially and evenly dispersing it. This allows the new mash to be continuously and dispersed from the long strip-shaped discharge port onto the already discharged positions in the fermentation pit. The spreading component follows the successive descent of the lifting component and the lateral movement of the moving frame, enabling the new mash to be spread from the top to the bottom layer. The material is laid layer by layer into the fermentation pit, thus achieving a seamless connection between the material collection and spreading operations. Throughout the process of old mash being discharged and new mash being fed into the pit, the lifting component is controlled by the controller to start and stop two electric push rods synchronously, so as to achieve precise vertical positioning and layer-by-layer advancement of the material collection and spreading components. The moving frame is controlled by the controller to drive the reciprocating screw to rotate through the third drive motor, which drives the material collection and spreading components to perform stable horizontal reciprocating motion. The two work together to enable the equipment to cover the working area of ​​each position in the fermentation pit according to the set path, and finally complete the integrated automatic operation of layered old mash discharge and new mash feeding in multiple rounds of solid-state fermentation.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention. Beneficial effects

[0016] 1. By integrating the receiving component and the spreading component on both sides of the same gantry and support plate, and using the lifting component and the lateral moving mechanism to achieve synchronous displacement of the two, the equipment can complete the continuous operation of digging out the old mash layer by layer and spreading the new mash layer by layer in the same station. There is no need to switch or move the equipment between the discharge and feeding processes, which greatly shortens the operation interval time and significantly improves the overall operation efficiency of multi-round solid fermentation in and out of the pit. 2. The receiving component adopts a combined structure consisting of a scraper, two symmetrical spiral blades, and a first granular pump. The scraper peels off the mash layer by layer in the fermentation pit through the circular motion of the scraper. With the help of the arc-shaped support plate, baffle box, conical guide frame and baffle cover, the scraped mash is gathered and contracted. Then, the two spiral blades transport it from both sides to the middle to the suction end of the first granular pump. This realizes the precise digging of mash in layers and the closed centralized transportation, effectively avoiding the mash from scattering everywhere and mixing between layers, ensuring the cleanliness of the discharge process and the integrity of the old mash layers. 3. The controller controls the synchronous start and stop of two electric push rods to achieve the progressive vertical advancement of the material receiving and spreading components. The third drive motor drives the reciprocating screw to rotate through the meshing of the worm gear and worm wheel. In conjunction with the transmission slider and spiral groove on the slide plate, the horizontal reciprocating motion of the gantry is realized. This allows the equipment to cover each area in the pit in sequence according to the set path, realizing the coordinated and precise control of vertical layering and horizontal segmentation, and effectively improving the adaptability of the equipment to the complex pit working environment. This invention achieves integrated automatic operation of layered discharge of old mash and layered entry of new mash into the fermentation pit. Through lifting and lateral movement linkage control covering the entire area of ​​the fermentation pit, the discharged material is clean and does not scatter, and the entered material is uniform and does not stratify, which significantly improves the efficiency of entering and leaving the pit, the degree of automation, and the consistency of fermentation quality.

[0024] In one embodiment: Refer to Figure 1-10An integrated machine includes a base frame 1. Multiple foot plates 40, made of Q235 steel, are symmetrically fixed to the bottom of the base frame 1.

[0026] like Figure 4-7As shown, the receiving component includes a first mounting box 10 fixed to one side of the support plate 8. An arc-shaped support plate 11 is fixed inside the first mounting box 10, located below two spiral blades 13. A baffle box 23 is fixed to the top of the arc-shaped support plate 11, with the top of the baffle box 23 extending above the first mounting box 10. A feeder is installed inside the first mounting box 10. The feeder includes a drive shaft 12 rotatably connected inside the first mounting box 10. Two spiral blades 13 are fixedly mounted on the drive shaft 12, with the spiral directions of the two spiral blades 13 symmetrically arranged.

A first drive motor 14 is fixed to one side of the first mounting box 10. The output shaft of the first drive motor 14 extends into the first mounting box 10 and is fixed to a drive shaft 15. A conveyor roller 16 is fixedly sleeved on the drive shaft 15. Multiple scrapers 17 are integrally and equally spaced on the outer circumferential side of the conveyor roller 16. The gap between the end of the scraper 17 and the surface of the arc-shaped support plate 11 is 1mm-2mm. One end of the drive shaft 15 extends to the outside of the first mounting box 10.

A baffle cover plate 26 is fixed to one side of the conical guide frame 24. One side of the baffle cover plate 26 extends to the other side of the first mounting box 10 and is fixedly connected to the other side of the first mounting box 10. An opening is provided at the bottom of the baffle cover plate 26.

[0027] like Figures 8-9As shown, the feeding component includes a second mounting box 25 fixed to the other side of the support plate 8. A conveying pipe 27 is fixed inside the second mounting box 25. A long strip-shaped discharge port 28 is opened on the bottom inner wall of the conveying pipe 27. A second drive motor 29 is fixed to one side of the second mounting box 25. One end of the second drive motor 29 extends into the conveying pipe 27 and is fixed with a conveying screw 30.

A second granulation pump 31 is fixed to one side of the top of the second mounting box 25. The discharge end of the second granulation pump 31 extends into the conveying pipe 27 and is fixedly connected to the top inner wall of the conveying pipe 27. The suction end of the second granulation pump 31 is used to connect to the pipeline for conveying the mash to be fermented. The first granulation pump 22 and the second granulation pump 29 are flexible impeller granulation pumps or screw slurry pumps.

[0028] like Figure 1 , Figure 2 and Figure 10 As shown, a power box 32 is fixed to one side of the base frame 1. Two reciprocating screws 33 are symmetrically rotatably connected inside the base frame 1. A sliding plate 34 extending into the base frame 1 is fixed to the inner side of the movable frame 2. A through hole is provided on the sliding plate 34, and the reciprocating screw 33 passes through the corresponding through hole. A transmission slider is fixedly provided on the inner wall of one side of the through hole, and the transmission slider cooperates with the spiral groove on the reciprocating screw 33. A mounting shaft 37 is fixed to one end of the reciprocating screw 33. One end of the mounting shaft 37 extends into the power box 32 and is rotatably connected to the inner wall of one side of the power box 32. A third drive motor 35 is fixed to one side of the power box 32. One end of the third drive motor 35 extends into the power box 32 and is connected to a drive assembly. The drive assembly includes a rotating shaft 36 fixedly mounted on the output shaft of the third drive motor 35. Two worm gears 38 are fixedly sleeved on the rotating shaft 36, and a worm wheel 39 is fixedly sleeved on the mounting shaft 37. The worm gears 38 and the worm wheel 39 mesh with each other. A controller is installed on the base frame 1. The controller is electrically connected to two electric push rods 5, a first drive motor 14, a first particle pump 22, a second drive motor 29, a second particle pump 31, and a third drive motor 35.

[0029] In this embodiment, the base frame 1 is first hoisted to the top opening of the fermentation pit and locked in place using the foot plates 40. After setting the operating parameters via the controller, the third drive motor 35 is started, driving the rotating shaft 36 to rotate. Through the meshing transmission of two worm gears 38 and corresponding worm wheels 39, the two mounting shafts 37 rotate synchronously, which in turn drives the two reciprocating screws 33 to rotate simultaneously. The reciprocating screws 33 cooperate with the transmission slider on the slide plate 34, causing the slide plate 34 to move laterally along the base frame 1, so that the moving frame 2, along with the gantry frame 3 and all components installed on it, moves as a whole to the starting end of the work area inside the fermentation pit. Subsequently, the two electric push rods 5 are activated to extend synchronously, pushing the adjusting plate 6 to move downward along the slide rail 9, so that the support plate 8 drives the material receiving component and the material spreading component to descend synchronously to the surface of the uppermost layer of mash inside the fermentation pit.

[0030] When discharging the old mash, the first drive motor 14 is started, driving the drive shaft 15 to rotate. This causes the conveyor roller 16 to drive the scraper 17 in a circular motion, scraping the surface old mash into the first mounting box 10. The scraped mash falls along the arc-shaped support plate 11 into the area where the spiral blades 13 are located. As the drive shaft 15 rotates, it drives the transmission shaft 12 to rotate through the second sprocket 19, chain 20, and first sprocket 18. The two spiral blades 13, which are symmetrical in spiral direction, transport the mash from both sides to the middle baffle box 23 area. The first granular pump 22 is started to extract the accumulated old mash through the pipeline to the outside of the fermentation pit. During the operation, the third drive motor 35 continuously drives the moving frame 2 to move laterally back and forth. After each lateral stroke, the electric push rod 5 drives the receiving component to descend 20-50cm (corresponding to the single layer height) until the bottom layer of old mash is cleaned.

[0031] After the discharge operation is completed, switch directly to the spreading operation. Connect the suction end of the second granular pump 31 to the new mash conveying pipe, start the second granular pump 31 to pump the new mash into the conveying pipe 27, and at the same time start the second drive motor 29 to drive the conveying screw 30 to rotate, pushing the new mash that has entered the conveying pipe 27 axially. During the pushing process, the mash is evenly sprinkled into the fermentation pit from the discharge port 28 at the bottom. During the spreading process, the moving frame 2 also maintains horizontal back-and-forth movement. After each horizontal stroke is completed, the electric push rod 5 drives the spreading component to descend by 3cm until the new mash is spread layer by layer.

[0032] In this embodiment, the material receiving component and the material spreading component are installed simultaneously on both sides of the support plate 8, which is based on engineering considerations in actual use. Without this integrated structure, calculations show that in a workshop setting with a dense cluster of pits, the time for equipment switching and secondary positioning is approximately 1.5-2 hours, and the reference error between the two positioning operations can reach 3-5cm. This can easily lead to the problem that the material spreading area and the material discharging area do not overlap, affecting the accuracy of layered laying.

[0033] In this embodiment, two symmetrical helical blades 13 are used, based on engineering considerations in actual use. If blades with a single helical direction are used, the efficiency of conveying the mash will be reduced, and the mash will easily accumulate and clump on one side of the tank, clogging the suction end of the first granular pump 22 and affecting the continuous operation of the discharge operation.

[0034] This application can be used in the field of brewing equipment technology, or in other fields applicable to this application.

[0035] In another embodiment: an improvement on the above embodiment: a multi-round solid-state fermentation layered old mash discharge and new mash input integrated machine, which is applied to the field of brewing equipment technology. The structure of this embodiment is basically the same as the above embodiment. The difference is that it is suitable for small fermentation pits and small brewing workshops with limited working space. The overall structure is basically the same as the above embodiment. The adjustment parameters are as follows: the stroke of the electric push rod 5 is 2m, the thickness of the foot plate 40 is 8mm, and the power of the first drive motor 14 and the second drive motor 29 is 1kW smaller than that of the above embodiment, which is suitable for the fermentation process requirements of small fermentation pits.

[0036] The alternative structure that can be selected in this embodiment is: replacing the transmission structure between the reciprocating screw 33 and the slide plate 34 with a gear and rack transmission structure. The rack is fixed on the inner wall of the base frame 1, and the gear is installed on the slide plate 34 and directly driven by the third drive motor 35. This structure is suitable for scenarios with higher requirements for lateral movement speed, but the positioning accuracy of this structure is 1cm-2cm lower than that of the reciprocating screw structure, and it is not suitable for fermentation operations of sauce-flavored liquor with high requirements for layering accuracy.
