Description

Technical Field

[0001] The invention relates to the technical field of automated brewing machinery, in particular to a mash feeding and steaming system used in a rich-flavor liquor brewing process. Background Art

[0002] Strong-flavor liquor, also often called Luzhou-flavor liquor, is a typical Chinese liquor flavor, known for its strong and rich aroma and taste. Strong-flavor liquor generally has a strong aroma layer, rich taste, and mellow body. It often uses sorghum, corn and other raw materials in the brewing process and adopts solid fermentation. In the process of brewing strong-flavor liquor, old mash, rice husk and grain need to be mixed to form new mash, which is then sent to the wine retort for distillation to produce liquor.

[0003] For example, the Chinese patent with the announcement number CN221069849U discloses a mash feeding system for an automated brewing process, comprising: a hopper and a frame, wherein a plurality of hoppers are movably mounted on the frame, and are respectively used to store grain, old mash, and rice husk; a first conveyor belt, which is arranged below the hopper; a first drive assembly, which is used to alternately drive the plurality of hoppers to reciprocate along the length direction of the first conveyor belt; and a stirring component, which is rotatably arranged at one end of the first conveyor belt, and is used to stir the grain, old mash, and rice husk to form mash.

[0004] However, the above scheme has the following shortcomings: in the above patent, the first driving component alternately drives the first hopper and the second hopper to reciprocate along the length direction of the first conveyor belt, so as to alternately spread the grain, old mash and rice husk on the first conveyor belt, and spread the grain, old mash and rice husk in layers on the first conveyor belt for distribution and pre-mixing. However, since the above patent uses two hoppers for spreading the materials, that is, the first hopper stores the mash and the second hopper stores the grain and rice husk respectively, stratification will occur when the grain, old mash and rice husk are alternately spread in turn by the first hopper and the second hopper, and the grain, old mash and rice husk cannot be relatively completely mixed before mixing and stirring, and then fully mixed through the stirring equipment. For this reason, we have introduced a mash feeding and steaming system for the rich-flavor liquor brewing process. Summary of the invention

Embodiment 2:

[0018] On the basis of Example 1, in order to control the amount of grain, old mash and rice husk discharged from the storage hopper, the adjustable discharging mechanism includes a slide plate 18, which is slidably connected to the storage hopper 9, one end of the slide plate 18 extends into the external environment, and the other end extends into the connecting cavity 14 and is fixed to the limiting plate 13, the limiting plate 13 is arranged in the connecting cavity 14, the connecting cavity 14 is opened in the storage hopper 9, a support spring 16 is fixedly connected in the connecting cavity 14, and the other end of the support spring 16 is fixedly connected to the limiting plate 13, when the turntable 24 drives the first lever 22 to rotate counterclockwise, the second lever 23 will be pushed to move to the left, and the movement of the second lever 23 drives the slide plate 18 to move synchronously, when the first lever 22 moves to the right, at this time, under the elastic force of the support spring 16, the second lever 23 moves to the right, and the slide plate 18 will move back and forth in the storage hopper 9; A groove 29 is provided at the lower end of the slide plate 18, and a movable plate 21 is provided in the groove 29. Both ends of the slide plate 18 are fixedly connected with a slide rod 20, and the slide rod 20 is slidably connected in the slide groove 15. The slide groove 15 is provided in the groove 29. A plurality of first through holes 17 are provided at the upper end of the slide plate 18, and a plurality of second through holes 26 are provided at the upper end of the movable plate 21. A screw rod 19 is movably connected to one side of the movable plate 21, and the screw rod 19 is screwed into the slide plate 18. One end of the screw rod 19 extends into the external environment and is fixedly connected to the knob 28. By rotating the knob 28, the screw rod 19 connected to its output end starts to rotate. Since the screw rod 19 is screwed into the slide plate 18, during the rotation of the screw rod 19, the movable plate 21 will move to the right. At this time, the distance between the first through hole 17 and the second through hole 26 becomes smaller, and the discharge amount of the material will also be relatively reduced. The transmission mechanism includes a second transmission motor 25, which is fixedly connected to the outside of the storage hopper 9. The output end of the second transmission motor 25 is fixedly connected to a turntable 24. The turntable 24 is fixedly connected to the first lever 22 at one end away from the second transmission motor 25. The first lever 22 is in contact with the second lever 23. The upper end of the second lever 23 is fixedly connected to the lower end of the slide plate 18. The second transmission motor 25 is turned on to drive the turntable 24 connected to its output end to rotate counterclockwise. The rotation of the turntable 24 drives the first lever 22 to start moving. Due to the elastic force of the support spring 16, the second lever 23 will always be in contact with the first lever 22. The stirring and mixing mechanism includes two connecting wheels 30, and a plurality of stirring blades 10 are fixedly connected to the outer side of the connecting wheel 30. The lower ends of the connecting wheel 30 and the stirring blades 10 are in contact with the upper end of the conveying belt 3. The upper end of the connecting wheel 30 is fixedly connected to the output end of the connecting motor 12, and the connecting motor 12 is fixedly connected to the upper end of the U-shaped connecting plate 11, and the U-shaped connecting plate 11 is fixedly connected to the upper end of the U-shaped bottom plate 1. When the two connecting motors 12 are turned on, the connecting wheels 30 connected to their output ends are respectively driven to rotate in opposite directions. The rotation of the connecting wheel 30 drives the plurality of stirring blades 10 to rotate. When the mixed material above the conveying belt 3 moves to the position of the plurality of stirring blades 10, the material will be driven to be stirred and conveyed, and the mixed material will be finally conveyed to the wine retort by the conveying belt 3.

[0019] Working principle: when in use, pour the old mash and rice husk into the two storage hoppers 9 on the right, pour the grain into the storage hopper 9 on the far left, and adjust the discharge amount of grain, old mash and rice husk according to the mixing ratio. Specifically, by turning the knob 28, the screw rod 19 connected to the output end starts to rotate. Since the screw rod 19 is screwed into the slide plate 18, during the rotation of the screw rod 19, the movable plate 21 will move to the right. At this time, the distance between the first through hole 17 and the second through hole 26 becomes smaller, and the discharge amount of the material will also be relatively reduced. The second transmission motor 25 is turned on to drive the turntable 24 connected to its output end to rotate counterclockwise. The rotation of the turntable 24 drives the first lever 22 to start moving. Because the second lever 23 is always in contact with the first lever 22 under the elastic force of the support spring 16, the second lever 23 is pushed to move leftward during the process of the turntable 24 driving the first lever 22 to rotate counterclockwise. The movement of the second lever 23 drives the slide plate 18 to move synchronously. When the first lever 22 moves to the right, the second lever 23 moves to the right under the elastic force of the support spring 16. At this time, the slide plate 18 moves back and forth in the storage hopper 9, so that the material passes through the first through hole 17 and the second through hole 26 and enters the material guide chamber 8. After the grain, old mash and rice husk enter the material guide chamber 8, they will enter the spiral mixing tube 5 again. The materials entering the spiral mixing tube 5 will be mixed, and the mixed grain, old mash and rice husk will fall to the upper end of the conveying crawler 3. The first transmission motor 4 is turned on to drive the roller 2 connected to its output end to start rotating, and the roller 2 rotates to drive the conveyor crawler 3 to start moving. At this time, the mixed material falling on the upper end of the conveyor crawler 3 will be driven to move. The two connecting motors 12 are turned on to drive the connecting wheels 30 connected to their output ends to rotate in opposite directions respectively. The connecting wheels 30 rotate to drive the plurality of stirring blades 10 to rotate. When the mixed material above the conveyor crawler 3 moves to the position of the plurality of stirring blades 10, the material will be driven to be stirred and transported. The materials after the initial mixing are mixed again by the plurality of stirring blades 10 rotating in opposite directions, and the mixed materials are finally transported to the wine retort by the conveyor crawler 3.
