Abstract
Description
Technical Field
[0001] This utility model relates to the field of winemaking technology, and in particular to a device for steaming wine mash. Background Technology
[0002] The feeding of the mash into the still is the core step in the distillation process of baijiu. By heating the mash, the alcohol (boiling point 78.3℃) is preferentially vaporized, separating from water and other solid substances. After condensation, the raw liquor (with an alcohol content of up to 50% vol) is formed. This process retains aroma substances (such as esters and alcohols) while removing impurities.
[0003] The traditional method of loading fermented mash into the still is by manually spreading it evenly into the still for distillation. Manual loading requires considerable skill from the workers, and the working environment is harsh due to the high temperatures, the large size of the still, and the overall challenging conditions. Therefore, loading robots have emerged, using robotic arms to automatically load the mash. However, before loading, the lid of the still needs to be manually closed for distillation, and after loading, the lid needs to be manually opened for replacement. This requires on-site observation and operation. Furthermore, opening or closing the lid can easily lead to accidental contact with the loading robot, potentially causing injury to the operator or damage to the robot due to impacts. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a device for automatically loading fermented mash into a still, eliminating the need for manual on-site operation, ensuring safety, and improving brewing efficiency.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stilling device for fermented mash includes a stilling area set on a support platform. Two rows of evaporation sections are arranged opposite each other in the stilling area. Multiple stills are spaced apart in each evaporation section. A stilling robot is positioned between the stills in two evaporation sections. The stilling robot includes a fixed base, a rotating base, a vertical arm, and a feeding arm. The rotating base is embedded in and rotatably connected to the fixed base, and is driven by a first motor. One end of the vertical arm is rotatably connected to the rotating base, and is driven by a second motor. The end of the vertical arm away from the rotating base is rotatably connected to the feeding arm, and is driven by a third motor, so that the fermented mash enters the still through the feeding arm. A support frame is provided on the side of the still that faces away from the loading robot. The support frame is equipped with a switch arm. One end of the switch arm is rotatably connected to the support frame, and the other end is equipped with a cover. The switch arm is driven by an opening and closing telescopic cylinder so that the cover can be placed on the still or rotated away from the still. An opening / closing limit switch is provided on the side wall near the opening of the still. When the cover is placed on the still, the opening / closing limit switch can be pressed down by the cover. A first positioning limit switch is provided on the opposite sides of the fixed base facing the still. A second positioning limit switch is provided on the side of the fixed base adjacent to the first positioning limit switch. A trigger is provided on the rotating base. When the feeding arm faces the still, the trigger can press down the first positioning limit switch. After the feeding arm rotates 90° away from the still, the trigger can press down the second positioning limit switch. The opening / closing limit switch, the first positioning limit switch, and the second positioning limit switch are electrically connected to the opening / closing telescopic cylinder and the first motor through a controller.
[0006] Furthermore, a threaded feeding rod is rotatably provided inside the feeding arm, and a guide funnel is provided at one end of the feeding arm, while a feeding pipe is rotatably provided at the other end. The feeding pipe is driven by a fourth motor, and a feeder is provided at the end of the feeding pipe away from the feeding arm.
[0007] Furthermore, the support platform is provided with the same number of pouring ports as the still, and a bottom plate is fixedly fitted at the bottom of the still. The bottom plate is located inside the pouring ports, and the two sides of the middle part of the bottom plate are respectively rotatably connected to the support platform. The bottom plate is driven by a discharge motor so that the still is turned over and the mash is poured out to the lower layer of the support platform. A steam hose is provided at the bottom of the still.
[0008] Furthermore, rotating shafts are fixedly installed on both sides of the middle part of the base plate. The end of the rotating shaft away from the base plate is rotatably connected to the support platform. A first gear is sleeved on one side of the rotating shaft. The discharge motor is fixedly installed on the support platform, and a reducer is installed at the output end of the discharge motor. A second gear that meshes with the first gear is installed at the output end of the reducer.
[0009] Furthermore, support mechanisms are respectively provided at opposite ends of the pouring port. Each support mechanism includes a support member and an electric telescopic rod. The support member is slidably connected to the side of the support platform facing away from the still via a sliding sleeve. The electric telescopic rod is used to drive the support member so that when the bottom plate is parallel to the support platform, the support member can abut against the bottom of the bottom plate. Furthermore, a position limit switch is provided on the side of the support mechanism facing away from the still. When the base plate is parallel to the support platform, the base plate can press down the position limit switch. The position limit switch, the discharge motor, the electric telescopic rod are electrically connected to the controller.
[0010] Furthermore, it also includes a condenser, the cover is provided with a gas guide pipe, the two ends of the gas guide pipe are respectively connected to the cover and the condenser, and the condenser is provided with a wine outlet.
[0011] The beneficial effects of this utility model are: 1. By controlling the extension of the telescopic cylinder, the lid rotates away from the still, and simultaneously the opening / closing limit switch is released. The controller, based on the signal from the limit switch, controls the first motor to rotate, causing the rotating base to rotate until the trigger presses down the first positioning limit switch. Then, the controller controls the second motor to rotate the vertical arm, allowing the feeding arm to extend into the still for loading. After loading is complete, the controller controls the feeding arm to reset and then controls the second motor to rotate until the trigger presses down the second positioning limit switch. The controller then controls the telescopic cylinder to shorten, allowing the lid to close on the still for distillation. During the loading process, the opening / closing limit switch, the first positioning limit switch, and the second positioning limit switch prevent interference between the feeding arm and the lid, ensuring the safe operation of the loading robot and the lid. Furthermore, no manual on-site operation is required, ensuring safety, improving brewing efficiency, and achieving automated loading of the mash.
[0012] 2. After distillation, the lid is opened, and the discharge motor drives the bottom plate to rotate, causing the still to flip and pour the mash into the lower support platform. This eliminates the need for manual movement of the still after distillation, improving brewing efficiency. Simultaneously, when the electric telescopic rod is extended, the support can move to the bottom of the bottom plate, restricting its rotation and ensuring stable operation of the still.

[0022] Please also see Figures 1 to 5 The preferred embodiment of the present invention provides a stilling device for fermented mash, which includes a stilling area set on a support platform 1, two rows of evaporation sections arranged opposite each other in the stilling area, multiple stills 2 spaced apart in the evaporation sections, and a stilling robot 3 arranged between the stills 2 in the two evaporation sections.
[0023] like Figure 1 As shown, the steaming robot 3 includes a fixed base 31, a rotating base 32, a vertical arm 33, and a feeding arm 34. The rotating base 32 is embedded in and rotatably connected to the fixed base 31, and is driven by a first motor 321. One end of the vertical arm 33 is rotatably connected to the rotating base 32, and is driven by a second motor 331. The end of the vertical arm 33 away from the rotating base 32 is rotatably connected to the feeding arm 34, and is driven by a third motor 341, so that the mash enters the steaming still 2 through the feeding arm 34. In this embodiment, one steaming robot 3 can steam the stills 2 on both sides.
[0024] In this embodiment, a threaded feeding rod is rotatably mounted inside the feeding arm 34. A guide funnel 35 is mounted at one end of the feeding arm 34, and a feeding pipe 36 is rotatably mounted at the other end. The feeding pipe 36 is driven by a fourth motor 361, and a feeder 37 is mounted at the end of the feeding pipe 36 furthest from the feeding arm 34. A conveyor belt 38 is mounted above the guide funnel 35 to transport the mash into the guide funnel 35. The feeding arm 34 in this embodiment can be the feeding mechanism of a modern steaming robot.
[0025] A support frame 21 is provided on one side of the still 2 facing away from the stilling robot 3. The support frame 21 is equipped with a switch arm 211. One end of the switch arm 211 is rotatably connected to the support frame 21, and the other end is equipped with a cover 22. The switch arm 211 is driven by an opening and closing telescopic cylinder 23 so that the cover 22 can be placed on the still 2 or rotated away from the still 2.
[0026] like Figure 1 As shown, an opening and closing limit switch 24 is provided on the side wall of the still 2 near its opening. When the cover 22 is placed on the still 2, the opening and closing limit switch 24 can be pressed down by the cover 22.
[0027] like Figure 1 and Figure 2As shown, a first positioning limit switch 311 is provided on the opposite sides of the fixed base 31 facing the still 2. A second positioning limit switch 312 is provided on the side of the fixed base 31 adjacent to the first positioning limit switch 311. A trigger 322 is provided on the rotating base 32. When the feeding arm 34 faces the still 2, the trigger 322 can press down the first positioning limit switch 311. After the feeding arm 34 rotates 90° away from the still 2, the trigger 322 can press down the second positioning limit switch 312. The opening and closing limit switch 24, the first positioning limit switch 311, and the second positioning limit switch 312 are electrically connected to the opening and closing telescopic cylinder 23 and the first motor 321 through the controller. In this embodiment, the controller is PLC control. The trigger ends of the first positioning limit switch 311 and the second positioning limit switch 312 are spherical structures, so that the trigger 322 can press down the corresponding first positioning limit switch 311 or second positioning limit switch 312 when it moves to the corresponding position.
[0028] In this embodiment, by controlling the extension of the opening and closing telescopic cylinder 23, the cover 22 rotates away from the still 2. Simultaneously, the opening and closing limit switch 24 is released. The controller controls the first motor 321 to rotate according to the signal from the opening and closing limit switch 24, causing the rotating seat 32 to rotate. After the trigger 322 presses down the first positioning limit switch 311, the controller controls the upright arm 33 to rotate via the second motor 331, allowing the feeding arm 34 to extend into the still 2 for feeding. After feeding is completed, the controller controls the feeding arm 34 to reset and then controls the second motor 331 to rotate until the trigger 322 presses down the second positioning limit switch 312. The controller then controls the opening and closing telescopic cylinder 23 to shorten, allowing the cover 22 to close onto the still 2 for distillation of the mash.
[0029] In this embodiment, during the steaming process, under the action of the opening and closing limit switch 24, the first positioning limit switch 311, and the second positioning limit switch 312, the feeding arm 34 will not interfere with the cover 22, ensuring the safe operation of the steaming robot 3 and the cover 22. Moreover, no manual on-site operation is required, ensuring safety, improving brewing efficiency, and realizing automated steaming of mash.
[0030] like Figure 3 As shown, the support platform 1 has the same number of pouring openings 101 as the still 2. A base plate 4 is fixedly fitted onto the bottom of the still 2, located within the pouring openings 101. The two sides of the center of the base plate 4 are rotatably connected to the support platform 1. The base plate 4 is driven by a discharge motor 41, causing the still 2 to flip and pour the mash onto the lower layer of the support platform 1. A steam hose 201 is installed at the bottom of the still 2.
[0031] A rotating shaft 401 is fixedly installed on both sides of the middle part of the base plate 4. The end of the rotating shaft 401 away from the base plate 4 is rotatably connected to the support platform 1. A first gear 402 is sleeved on one side of the rotating shaft 401. The discharge motor 41 is fixedly installed on the support platform 1, and a reducer 411 is installed at the output end of the discharge motor 41. A second gear 412 that meshes with the first gear 402 is installed at the output end of the reducer 411.
[0032] After distillation is complete, the cover 22 is opened, and the bottom plate 4 is driven to rotate by the discharge motor 41, causing the still 2 to flip and pour the mash into the lower layer of the support platform 1. This allows the mash to be discharged after distillation without the need for manual handling of the still 2, thus improving the efficiency of winemaking.
[0033] like Figure 4 and Figure 5 As shown, support mechanisms are provided at opposite ends of the pouring port 101. Each support mechanism includes a support member 5 and an electric telescopic rod 51. The support member 5 is slidably connected to the side of the support platform 1 facing away from the still 2 via a sliding sleeve 52. The electric telescopic rod 51 is used to drive the support member 5 so that when the bottom plate 4 is parallel to the support platform 1, the support member 5 can abut against the bottom of the bottom plate 4.
[0034] In this embodiment, two sliding sleeves 52 are fixedly provided on each side of the pouring port 101. The ends of the two support members 5 facing away from the pouring port 101 are connected by a connecting rod 54. One end of the electric telescopic rod 51 is fixedly connected to the support platform 1, and the other end is connected to the connecting rod 54, thereby driving the two support members 5 to move along the sliding sleeves 52, so that the support members 5 can slide into or out of the pouring port 101, thereby locking or releasing the base plate 4.
[0035] A limit switch 53 is provided on the side of the support mechanism facing away from the still 2. When the base plate 4 is parallel to the support platform 1, the base plate 4 can press down the limit switch 53. The limit switch 53, the discharge motor 41, the electric telescopic rod 51 are electrically connected to the controller. In this embodiment, the limit switch 53 is connected to the support platform 1 through a bracket 531.
[0036] When it is necessary to pour out the mash, the controller controls the discharge motor 41 to rotate forward, and the still 2 flips over to pour the mash into the lower layer of the support platform 1. After the mash is poured out, the controller controls the discharge motor 41 to rotate in reverse until the bottom plate 4 presses down to the limit switch 53. The controller then controls the electric telescopic rod 51 to extend, and the support member 5 moves to the bottom of the bottom plate 4, and the support member 5 abuts against the bottom plate 4 to limit the rotation of the bottom plate 4.
[0037] like Figure 1As shown, it also includes a condenser 6, and the cover 22 is provided with a gas guide pipe 61. The two ends of the gas guide pipe 61 are respectively connected to the cover 22 and the condenser 6. The condenser 6 is provided with a wine outlet 62. The condenser 6 is located on the lower layer of the support platform 1.
[0038] The operation process of the fermentation mash loading device in this embodiment is as follows: The control cylinder 23 extends, causing the cover 22 to rotate away from the still 2. At the same time, the opening and closing limit switch 24 is released. The controller controls the first motor 321 to rotate according to the signal from the opening and closing limit switch 24, causing the rotating seat 32 to rotate. After the trigger 322 presses down the first positioning limit switch 311, the controller controls the upright arm 33 to rotate through the second motor 331, so that the feeding arm 34 can extend into the still 2. The conveyor belt 37 transports the mash to the guide funnel 35, so that the mash can be discharged along the feeding arm 34, the distribution pipe 36, and the distributor 37, and is fed into the still 2.
[0039] After the still is filled, the controller controls the feeding arm 34 to reset and then controls the second motor 331 to rotate until the trigger 322 presses down the second positioning limit switch 312. The controller then controls the opening and closing telescopic cylinder 23 to shorten, so that the cover 22 can be closed on the still 2 to distill the mash.
[0040] After distillation, the lid 22 is opened, and the controller controls the electric telescopic rod 51 to shorten, causing the support to move away from the pouring port 101. The discharge motor 41 drives the bottom plate 4 to rotate, causing the still 2 to flip and pour the mash into the lower layer of the support platform 1. After the mash is poured out, the controller controls the discharge motor 41 to reverse until the bottom plate 4 presses down the limit switch 53. Based on the signal from the limit switch 53, the controller controls the electric telescopic rod 51 to extend, and the support 5 moves to the bottom of the bottom plate 4, where it abuts against the bottom plate 4 to restrict the rotation of the bottom plate 4.
