Description

Technical Field

[0001] This utility model belongs to the field of liquor production technology, specifically relating to a spreading and mixing device for liquor production. Background Technology

[0002] Baijiu (Chinese white liquor) is made primarily from grains through a series of processes, including fermentation. In the production of baijiu, high-quality brewing raw materials are crushed, washed, steamed, and gelatinized.

[0048] The feeding mechanism 3 is used to guide the raw materials into the spreading tray 8;

[0049] The material dispersing mechanism 4 is used to disperse the raw materials in the spreading tray 8;

[0050] The spraying mechanism 5 includes a liquid supply component and a spraying component. The liquid supply component is located on one side of the work frame 1, and the spraying component is located on the mounting frame 7. The liquid supply end of the liquid supply component is connected to the liquid inlet end of the spraying component, and the spraying end of the spraying component faces the spreading tray 8.

[0051] As a preferred embodiment, the lifting mechanism 6 includes a lifting seat 61 and two hydraulic cylinders 62;

[0052] Two hydraulic cylinders 62 are arranged at intervals below the drying opening 11 along the left and right direction of the work frame 1, and the driving end of the hydraulic cylinder 62 is fixedly connected to the bottom of the lifting seat 61.

[0053] The bottom of the drying tray 8 is fixedly connected with two locking blocks 81 at intervals along the left and right directions of the work frame 1;

[0054] The top of the lifting seat 61 has two slots 63 corresponding to the two locking blocks 81, and the locking blocks 81 engage with the slots 63.

[0055] In this embodiment, the lifting seat 61 is driven synchronously by the dual hydraulic cylinders 62. The locking block 81 and the locking groove 63 cooperate to ensure the stable lifting and lowering of the drying tray 8. Several handle grooves are provided on the outer peripheral wall of the drying tray 8 to facilitate the workers to remove the drying tray 8 from the lifting seat 61. The cooperation between the locking groove 63 and the locking block 81 also facilitates the quick disassembly and cleaning of the drying tray 8.

[0056] As a preferred embodiment, the reciprocating drive mechanism 2 includes two sets of reciprocating drive components 21;

[0057] The front and rear side walls of the work frame 1 are provided with mounting slots 12 corresponding to the two sets of reciprocating drive components 21;

[0058] The two sets of reciprocating drive components 21 are respectively installed in the mounting slots 12 on the front and rear side walls of the work frame 1;

[0059] The reciprocating drive assembly 21 includes a first motor 22, a lead screw 23, a lead screw nut 24, a slide bar 25, and a guide sleeve 26;

[0060] The first motor 22 is fixedly installed on the left side wall of the work frame 1. The drive end of the first motor 22 passes through the work frame 1 and extends into the mounting groove 12, and is connected to the left end of the lead screw 23. The right end of the lead screw 23 is rotatably connected to the right side wall of the mounting groove 12. The slide rod 25 is horizontally fixedly connected in the mounting groove 12 and is spaced apart from the lead screw 23. The nut of the lead screw 23 is threaded on the lead screw 23. The guide sleeve 26 is slidably fitted on the slide rod 25. The lead screw nut 24 and the guide sleeve 26 are fixedly connected. The bottom of the mounting frame 7 is fixedly connected to the top of the guide sleeve 26. The mounting frame 7 is erected above the work frame 1 along the front-back direction of the work frame 1.

[0061] In this embodiment, by setting the reciprocating drive mechanism 2 to be controlled synchronously by two sets of reciprocating drive components 21, the mounting frame 7 is prevented from tilting. The first motor 22 drives the lead screw 23 to rotate. With the cooperation of the guide sleeve 26 and the slide rod 25, the lead screw nut 24 and the guide sleeve 26 move synchronously on the lead screw 23 and the slide rod 25, respectively. This enables the mounting frame 7 to move horizontally reciprocally along the left and right directions of the working frame 1, thereby driving the feeding mechanism 3, the dispersing mechanism 4 and the spraying component to move synchronously back and forth. This ensures that the feeding and dispersing mechanisms 4 evenly cover the entire area of ​​the spreading tray 8, improving the consistency of spreading.

[0062] As a preferred embodiment, the feeding mechanism 3 includes a hopper box 31, a guide box 32, a second motor 33, a feeding shaft 34, and several feeding plates 35;

[0063] The upper end of the hopper box 31 is hollow, the lower end of the hopper box 31 is connected to the upper end of the guide box 32, and the right side wall of the guide box 32 is fixedly connected to the left side wall of the mounting frame 7.

[0064] The second motor 33 is fixedly installed on the front side wall of the guide box 32. The drive end of the second motor 33 extends backward through the guide box into the guide box 32 and is connected to the front end of the feeding shaft 34. The rear end of the feeding shaft 34 is rotatably connected to the rear inner side wall of the guide box 32. Several feeding plates 35 are fixedly connected to the outer peripheral wall of the feeding shaft 34 and are arranged in an array around the periphery.

[0065] In this embodiment, the upper section of the hopper box 31 has a rectangular structure, and the hopper box 31 stores cooked grain raw materials. There are 6 feeding plates 35, and the outer end face of the feeding plate 35 away from the feeding shaft 34 is an arc surface. The outer end of the feeding plate 35 away from the feeding shaft 34 can fit against the left and right inner side walls of the guide box 32. The feeding plate 35 fits against the inner wall of the guide box 32 to form a sealed cavity to prevent material leakage. The front and rear side walls of the feeding plate 35 abut against the front and rear inner side walls of the guide box 32, respectively, and the feeding plate 35 can rotate inside the guide box 32. The length direction of both the hopper box 31 and the guide box 32 is along the working frame. The front-to-back distribution of the material guide box 32 facilitates the spreading of the raw materials along the width of the spreading tray 8. The length of the material guide box 32 matches the width of the spreading tray 8, ensuring that the material is evenly spread along the width. The second motor 33 drives the feeding shaft 34 to rotate and drives the feeding plate 35 to rotate, quantitatively feeding the cooked grain in the hopper box 31 into the material guide box 32. The cooked grain is evenly fed to the spreading tray 8 through the material guide box 32, and in conjunction with the reciprocating drive mechanism 2, drives the feeding mechanism 3 on the mounting frame 7 to move, so that the raw materials in the hopper box 31 can fill the spreading tray 8. This replaces manual shoveling, realizes continuous and quantitative feeding, and improves the uniformity of spreading.

[0066] As a preferred embodiment, the material handling mechanism 4 includes a third motor 41, a material handling shaft 42, and several material handling plates 43;

[0067] The third motor 41 is fixedly installed on the front side wall of the mounting frame 7. The drive end of the third motor 41 extends backward through the mounting frame 7 and into the mounting frame 7 and is connected to the front end of the bulk material rotating shaft 42. The rear end of the bulk material rotating shaft 42 is rotatably connected to the rear inner side wall of the mounting frame 7. Several bulk material plates 43 are fixedly connected to the outer peripheral wall of the bulk material rotating shaft 42 and are arranged in a circumferential array. The bulk material plates 43 can extend into the spreading tray 8.

[0068] In this embodiment, the first motor 22 of the reciprocating drive mechanism 2 drives the mounting frame 7 to move the feeding mechanism 3 along the length of the spreading tray 8. After the cooked raw material is laid in the spreading tray 8 by the feeding mechanism 3, the first motor 22 is turned off, and then the first motor 22 is started again to rotate in the opposite direction, driving the material dispersing mechanism 4 on the mounting frame 7 to move slowly in the opposite direction along the length of the spreading tray 8. At the same time, the third motor 41 is started to drive the material dispersing plate 43 to rotate and disperse the cooked grain raw material, promote the penetration of cold air, accelerate cooling, and the mechanized dispersing replaces manual stirring, improving cooling efficiency. The material dispersing plate 43 is distributed in a circumferential array, covering the entire width of the spreading tray 8.

[0069] In other embodiments of this solution, to accelerate cooling efficiency, an exhaust fan can be installed on the mounting bracket 7, and an exhaust hood can be connected to the exhaust end of the exhaust fan. The exhaust hood has a rectangular cross-section, and its length is distributed along the front-back direction of the cooling tray 8.

[0070] In other embodiments of this solution, a throwing plate is fixedly connected to the outer end of the bulk material plate 43. The throwing plate is set perpendicular to the bulk material plate 43 and is used to throw the raw materials.

[0071] As a preferred embodiment, the liquid supply assembly includes a liquid storage tank 51, a liquid supply pump 52, and a liquid infusion hose 53;

[0072] The storage tank 51 and the supply pump 52 are both located on the left side of the work frame 1. The storage tank 51 stores the yeast liquid. The outlet of the storage tank 51 is connected to the inlet of the supply pump 52. The outlet of the supply pump 52 is connected to the inlet of the infusion hose 53. The outlet of the infusion hose 53 is connected to the inlet of the spraying assembly.

[0073] In this embodiment, the liquid supply pump 52 delivers the yeast liquid in the storage tank 51 to the spray pipe 54 through the liquid delivery hose 53. The structure is simple and easy to implement. In addition, the storage tank 51 is also provided with a liquid filling port for easy liquid addition.

[0074] As a preferred embodiment, the spraying assembly includes a spray pipe 54 and a plurality of spray heads 55;

[0075] The spray pipe 54 is fixedly installed on the inner top wall of the mounting frame 7 along the length direction of the mounting frame 7 and is located above the material distribution mechanism 4. Several spray heads 55 are arranged in an array along the length direction of the spray pipe 54, and the spray direction of the spray heads 55 is towards the spreading tray 8.

[0076] In this embodiment, the spray pipe 54 is fixedly installed on the inner top wall of the mounting frame 7 and located directly above the material distribution plate 43. After the cooked grain raw materials are dispersed and cooled by the material distribution mechanism 4, the spraying components work together so that when the spray head 55 sprays the yeast liquid towards the spreading tray 8, the yeast liquid is sprayed onto the raw materials in the spreading tray 8 and also onto the material distribution plate 43. As the material distribution plate 43 rotates, the rod rotates to disperse the droplets, avoiding local liquid accumulation. This allows the yeast liquid and the raw materials in the spreading tray 8 to mix more thoroughly. Mechanized dispersing replaces manual stirring and promotes uniform adsorption of yeast.

[0077] The working principle of this utility model is as follows:

[0078] In use, the cooked grain is poured into the hopper box 31 (the upper part of the hopper box 31 has a rectangular opening for easy batch feeding). At this time, any two material-dispensing plates 35 in the guide box 32 are horizontally distributed, so that the material-dispensing plates 35 are in contact with the inner wall of the guide box 32 to prevent material leakage. During the feeding and spreading stage, the feeding mechanism 3 is started, the second motor 33 is turned on, and the feeding shaft 34 is driven to rotate the six material-dispensing plates 35. The material-dispensing plates 35 push the cooked grain from the hopper box 31 into the guide box 32 to realize feeding. At the same time, the first motor 22 of the two sets of reciprocating drive components 21 is started, which drives the mounting frame 7 to move horizontally along the length of the spreading tray 8. The cooked grain falls through the guide box 32 and spreads the spreading tray 8 with the movement of the mounting frame 7. During the dispersing and cooling stage, after the feeding is completed, the first motor 22 is turned off, and the hydraulic cylinder 62 is started to drive the spreading tray 8 to move upward until the dispersing plate 43 can be inserted into the cooked grain raw material layer of the spreading tray 8. Then the first motor is started in reverse. 22. Move the mounting frame 7 in the reverse direction and start the third motor 41 to drive the bulk material rotating shaft 42 to rotate the bulk material plate 43. The bulk material plate 43 inserts into the cooked grain layer, breaks it up and throws it up to increase the heat dissipation area and accelerate cooling. During the mixing stage, when the temperature of the cooked grain drops to the target value, start the liquid supply pump 52 to deliver the yeast liquid to the spray pipe 54 through the liquid delivery hose 53. The array of spray heads 55 sprays the yeast liquid evenly onto the surface of the cooked grain in the spreading tray 8. Some of the yeast liquid adheres directly to the cooked grain, and some is sprayed onto the rotating bulk material plate 43. At the same time, start the third motor 41 to drive the rotation of the bulk material plate 43 to disperse the splashed yeast liquid and avoid local over-wetting. The bulk material plate 43 continuously turns the cooked grain to ensure the uniformity of the mixing of yeast and raw materials. After the mixing is completed, start the lifting mechanism 6 to drive the spreading tray 8 to descend. Use the handle groove to remove the clamping block 81 of the spreading tray 8 from the clamping slot 63 of the lifting seat 61 and transfer it directly to the fermentation section.

It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
