Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grain moistening machine technology, and more specifically, it relates to a grain moistening machine mixing device. Background Technology
[0002] Grain moistening machines are key pieces of equipment in the brewing and grain processing industries, primarily used for wetting and mixing grain raw materials. In traditional production processes, grains need to undergo a proper wetting process to achieve the ideal moisture content, a process that directly impacts subsequent processes such as cooking and saccharification. However, existing grain moistening machines have revealed several technical limitations in practical use, directly affecting production efficiency and product quality.
[0003] Traditional grain wetting machines typically employ a simple paddle structure for their mixing devices, which makes it difficult to achieve uniform mixing and effective movement of the grain. Grain tends to accumulate and form dead zones during mixing, leading to uneven wetting. Some machines attempt to improve the effect by increasing the mixing intensity, but this often results in increased grain breakage, affecting the quality of the final product. The grain flow lacks effective guidance during mixing, frequently resulting in localized over-mixing while other areas are under-mixed.
[0004] The tank structure of existing grain mixing machines is mostly a simple cylindrical shape, which is not conducive to the natural flow of grain. During the mixing process, the grain tends to accumulate at the bottom of the tank, resulting in low mixing efficiency. Utility Model Content
[0005] In view of this, the present invention provides a grain moistening machine mixing device that can guide the grain to move within the grain moistening machine and improve mixing efficiency.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a grain moistening machine mixing device, which includes a grain moistening tank and grain moistening blades. The grain moistening tank is a spindle-shaped tank structure with an opening at the top and a detachable structure at the bottom. The grain moistening blades are spiral iron sheets located on the inner wall of the grain moistening tank and are used to mix the grain inside the grain moistening tank. The grain moistening tank and the grain moistening blades are integrally formed.
[0008] The technical effects of the grain moistening mixing device provided by this utility model are as follows: the grain moistening tank adopts a spindle-shaped tank structure with an opening at the top to facilitate the entry and exit of grain, the bottom detachable structure facilitates cleaning and maintenance, the grain moistening blades are spiral iron sheets that can effectively mix grain, and the one-piece molding design enhances the stability and durability of the overall structure.
[0009] Based on the above technical solution, the grain moistening machine mixing device of this utility model can be further improved as follows:
[0010] The grain moistening leaf consists of multiple pieces, which are integrally formed with the grain moistening tank and are fixed to the inner wall of the grain moistening tank in a spiral shape from top to bottom. The highest point of the grain moistening leaf is at the same height as the opening of the grain moistening tank, and the lowest point of the grain moistening leaf is at the same height as the detachable bottom of the grain moistening tank.
[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the multi-blade design improves mixing efficiency and uniformity, the spiral arrangement covers the entire inner wall of the tank from top to bottom to ensure no mixing dead corners, and the blade height is aligned with the tank opening and the removable bottom part to ensure maximum mixing range.
[0012] Furthermore, the top of the grain-moistening blade is curved at the end near the opening of the grain-moistening tank. The center of the curve is located on the plane where the grain-moistening blade is located, away from the axis, and the center does not coincide with the grain-moistening blade.
[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the arc design reduces the resistance of grain during the mixing process, and the layout with the center located outside the blade plane optimizes the grain flow path. This structure can guide the grain to enter the mixing area more smoothly.
[0014] Furthermore, the arc of the curved structure at the tip of the grain leaf is π / 4 to π / 3.
[0015] Furthermore, the spiral direction of the grain moistening blades is the same as the rotation direction of the grain moistening tank.
[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the thread direction to be the same as the rotation direction, the grain can enter the bottom of the grain moistening tank under the guidance of the moistening blades as the grain moistening tank rotates.
[0017] Furthermore, a connecting rod is provided between adjacent grain-moistening leaves. The connecting rod is parallel to the axis of the grain-moistening tank, and a mixing plate is provided on the side wall of the connecting rod. The mixing plate and the connecting rod are located on the same plane.
[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the connecting rod enhances the structural stability between multiple blades, the arrangement parallel to the axis does not affect the grain flow, and the mixing plate provides additional mixing effect to improve the mixing uniformity.
[0019] Meanwhile, the mixing board can mimic the shovel stirring of workers, ensuring consistency in frequency and intensity, and making the grain evenly moist during the mixing process; in addition, the mixing board can peel off the outer film of sorghum during the mixing process without damaging the sorghum skin.
[0020] Furthermore, the grain moistening tank is composed of multiple parts, including a first barrel structure, a second barrel structure, a third barrel structure, and a fourth barrel structure. The cross-section of the first barrel structure is a trapezoidal structure with its bottom edge in contact with the second barrel structure. The cross-section of the second barrel structure is a cylindrical structure. The third barrel structure is a trapezoidal structure with its bottom edge in contact with the second barrel structure. The fourth barrel structure is located at the lowest point of the grain moistening tank and is a trapezoidal structure with its bottom edge in contact with the third barrel structure.
[0021] The beneficial effects of adopting the above-mentioned improvement scheme are: the segmented structure facilitates manufacturing and transportation; the barrel structure with different cross-sectional shapes adapts to the needs of different mixing stages; and the combination of trapezoidal and cylindrical shapes optimizes the utilization rate of the internal space of the tank.
[0022] Furthermore, the third and fourth barrel structures are detachably connected, and the angle between the waist and bottom edge of the third barrel structure section is greater than the angle between the waist and bottom edge of the fourth barrel structure section.
[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the detachable design facilitates bottom cleaning and maintenance, the cross-sectional waist design with different angles adapts to the flow characteristics of grain at different positions, and the large included angle structure is conducive to the concentration of grain towards the outlet.
[0024] Furthermore, the angle between the cross sections of the first barrel structure and the second barrel structure is equal to the angle between the cross sections of the third barrel structure and the second barrel structure, and the angle is 5-10°.
[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the 5-10° included angle ensures that the grain can flow smoothly, the symmetrical included angle design makes the grain evenly stressed during the process of entering and exiting, and this angle range has been verified to effectively prevent grain from piling up.
[0026] Compared with the prior art, the beneficial effects of the grain moistening and mixing device provided by this utility model are:
[0027] The spindle-shaped tank structure conforms to the material flow characteristics, with an opening at the top for easy feeding and a tapering structure at the bottom for concentrated material discharge. Spiral wetting blades are continuously arranged along the inner wall, forming a complete material lifting channel to ensure that the grain is fully turned and evenly wetted during the mixing process.
[0028] The one-piece molded blade and tank structure eliminates stress concentration problems that may occur with traditional welding or bolted connections, improving overall mechanical strength and reducing the likelihood of deformation during long-term operation. The blade tip features a specific arc transition, effectively reducing material flow resistance and preventing localized accumulation of grain during mixing. The combined design of the connecting rod and mixing plate enhances the rigidity of the mixing system while providing auxiliary mixing, resulting in more uniform grain mixing.
[0029] The tank adopts a segmented structure, with the cross-sectional shape of each segment optimized to meet material flow requirements. The trapezoidal structure of the first and third segments guides the material through a smooth transition, the cylindrical structure of the middle section ensures ample mixing space, and the removable bottom section facilitates maintenance and cleaning. The connection angles of each segment are rationally set to ensure structural stability while avoiding dead zones in material flow. The third and fourth segments employ a differentiated inclination angle design to ensure optimal flow performance of the material during the discharge stage.
[0030] This device excels in operational efficiency. The spiral blade layout reduces energy consumption during the mixing process, while the arc-shaped structure minimizes unnecessary power loss. Its segmented construction facilitates transportation and on-site assembly, and the detachable connection simplifies daily maintenance. The overall structure fully considers the requirements of grain processing technology, achieving advanced industry standards in mixing effect, energy consumption control, ease of operation, and service life.

The alignment of the helical direction with the tank's rotation direction ensures an ideal material movement path.
[0061] The combined structure of the connecting rod and mixing plate enhances mechanical strength while providing auxiliary mixing functionality, resulting in more uniform material mixing.

This device demonstrates significant advantages in mixing efficiency, ease of operation, and maintenance convenience.
[0063] When using, tilt the grain moistening container 1, place the grain that needs to be moistened inside the container 1, and rotate the container 1. As the container 1 rotates, the grain enters its interior.

When the container 1 has rotated a sufficient number of times, the grain, guided by the blades 2, reaches the lowest point of the container 1. Remove the grain from the container 1, and the moistening process is complete.
