Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of bread processing, and particularly relates to a quantitative mixing device for enzyme preparations used in bread preparation. Background Art
[0002] Enzyme preparations refer to products containing enzymes, which can be divided into liquid enzyme preparations and solid enzyme preparations. Composition: Enzyme preparations usually consist of enzyme proteins and cofactors. Enzyme proteins are the protein parts with catalytic activity, which determine the specificity and catalytic function of the enzyme; cofactors can be metal ions or organic small molecules, which help enzyme proteins play their catalytic roles. Classification: According to the types of catalytic reactions, enzyme preparations can be divided into six major categories, namely oxidoreductases, transferases, hydrolases, lyases, isomerases, and synthases. For example, amylase belongs to hydrolases and can catalyze the hydrolysis of starch into glucose, maltose, etc.; glucose oxidase belongs to oxidoreductases and can catalyze the oxidation of glucose to produce gluconic acid and hydrogen peroxide. Enzyme preparations play a key role in bread making. For example, various enzyme preparations such as maltogenic amylase, fungal α-amylase, xylanase, and lipase are often used to improve the quality of bread. They can slow down the aging rate of bread, keep the bread fresh and soft, extend the shelf life of bread, and reduce the economic losses of merchants.
[0003] However, in the process of mixing liquid enzyme preparations, the mixing position of the liquid enzyme preparations is fixed, and the position of the mixing rod cannot be adjusted according to the mixing needs. The fixed position of the mixing rod may not effectively eliminate the concentration gradient generated during the mixing of liquid enzyme preparations. As the mixing progresses, the concentration of enzyme preparations in the area near the mixing rod may be relatively low, while the concentration in the area far from the mixing rod is relatively high, making it difficult to achieve a uniform distribution of the enzyme preparation concentration throughout the container.

Detailed implementation manners
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0028] The following will, with reference to the drawings, elaborate on the technical solutions provided by various embodiments of the present invention for a quantitative mixing device for enzyme preparations used in making bread.
[0029] Refer to Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a quantitative mixing device for an enzyme preparation for making bread, including a mixing cylinder 1. A detachable cylinder cover 11 is provided at the top of the mixing cylinder 1, and a feed inlet 12 is provided on the cylinder cover 11. A mixing driving member 2 is provided on the cylinder cover 11. The mixing driving member 2 is rotatably connected to the cylinder cover 11. Three mixing stirring members 3 are provided on the mixing driving member 2. All three mixing stirring members 3 are drivingly connected to the mixing driving member 2. A stirring adjusting member 4 is provided on each mixing stirring member 3. The stirring adjusting member 4 is rotatably connected to the mixing stirring member 3. An intermediate mixing member 5 is provided at the middle position of the mixing driving member 2. The intermediate mixing member 5 can mix the enzyme preparation at the middle position of the mixing cylinder 1. A discharge pipe 13 is provided at the top of the mixing cylinder 1.
[0030] Specifically, the mixing driving member 2 includes a mixing motor 21, a central gear 22, a driving plate 23 and a driving shaft 24. The central gear 22 is horizontally fixedly connected to the inner top of the cylinder cover 11. The driving shaft 24 is vertically arranged on the top of the driving plate 23. The driving shaft 24 passes through the central gear 22 and is rotatably connected to the central gear 22. The mixing motor 21 is located at the top of the cylinder cover 11 and is drivingly connected to the driving shaft 24. Three driving ends 25 are provided on the driving plate 23. A rotatably connected rotating shaft 26 is provided on each driving end 25. An upper gear 27 is provided at the top of the rotating shaft 26. The upper gear 27 meshes with the central gear 22. A lower gear 28 is provided at the bottom of the rotating shaft 26.
[0031] Specifically, each mixing stirring member 3 includes a stirring shaft 31, a connecting gear 32, a connecting shaft 33 and a connecting plate 34. The connecting shaft 33 is rotatably connected to the driving end 25. The connecting gear 32 is located on the connecting shaft 33 and the connecting gear 32 meshes with the lower gear 28. One end of the connecting plate 34 is fixedly connected to the connecting shaft 33. The top of the stirring shaft 31 is fixedly connected to the other end of the connecting plate 34. Four sliding grooves 35 are provided on the stirring shaft 31.
[0032] When mixing the enzyme preparation in the mixing cylinder 1, the mixing motor 21 works to drive the driving plate 23 to rotate. When the driving plate 23 rotates, it will drive the three upper gears 27 to rotate around the central gear 22 respectively. When the three upper gears 27 rotate, the rotating shafts 26 will rotate on the driving ends 25, thereby driving the three lower gears 28 to rotate respectively. When the lower gear 28 rotates, it will drive the connecting gear 32 to rotate on the driving end 25 through the connecting shaft 33. When the connecting shaft 33 rotates, it will drive the connecting plate 34 to rotate. When the connecting plate 34 rotates, it will drive the stirring shaft 31 to rotate in the mixing cylinder 1 to mix the enzyme preparation.
[0033] Specifically, the stirring adjustment member 4 includes an adjustment rod 41, a limiting rod 42, and three adjustment assemblies 43. The adjustment rod 41 is rotatably connected within the stirring shaft 31. A threaded section is provided on the adjustment rod 41. The limiting rod 42 is located beside the adjustment rod 41. The three adjustment assemblies 43 are arranged at equal intervals on the stirring shaft 31, and the adjustment assemblies 43 are slidably engaged with the adjustment rod 41.
[0034] Specifically, each adjustment assembly 43 includes an adjustment sleeve 431, four mounting seats 432, four adjustment plates 433, and four stirring rods 434. The adjustment sleeve 431 is threadedly connected to the threaded section, and the adjustment sleeve 431 is slidably engaged with the limiting rod 42. The four mounting seats 432 are circumferentially distributed on the adjustment sleeve 431. The middle position of the adjustment plate 433 is rotatably connected to the chute 35. One end of the adjustment plate 433 is rotatably connected to the mounting seat 432. The stirring rod 434 is connected to the other end of the adjustment plate 433. An internal hexagonal groove 435 is provided at the top of the adjustment rod 41, and the internal hexagonal groove 435 is located at the driving plate 23.
[0035] When the stirrer is mixing the enzyme preparation in the mixing cylinder 1, the stirring angle can be adjusted. At this time, an internal hexagonal tool can be inserted into the internal hexagonal groove 435 to drive the adjustment rod 41 to rotate within the stirring shaft 31. The rotation of the adjustment rod 41 will drive the position of the adjustment sleeve 431 to move upward or downward on the limiting rod 42. The movement of the position of the adjustment sleeve 431 will respectively drive the angular positions of the four adjustment plates 433 to rotate, and will respectively drive the position angles of the four stirring rods 434 to rotate, thereby changing the inclination angle position of the horizontally arranged stirring rods 434 during the mixing process of the enzyme preparation; Promote the overall flow of materials: The inclined stirring rods 434 can push the enzyme preparation to form a more complex flow path in the container, no longer limited to the single flow mode during horizontal rotation. It can cause strong convection of the enzyme preparation in both the vertical and horizontal directions, thus covering all areas within the container more comprehensively, reducing the mixing dead zones, and enabling the enzyme preparation to be mixed more evenly.
[0036] Enhance micro - mixing: The change in the inclination angle will cause the stirring rods 434 to generate forces in different directions on the enzyme preparation during rotation, increasing the shear and collision frequencies between the materials. This shear and collision action helps to break up the agglomerates or regions with too high local concentrations in the enzyme preparation, enabling the enzyme preparation to come into contact and mix more fully at the micro - level, improving the mixing uniformity.
[0037] Accelerate material circulation: The inclined stirring rod 434 can guide the enzyme preparation to form a more efficient circulation flow. For example, when the stirring rod 434 is inclined at a certain angle, the enzyme preparation will flow upward or downward along the inclined direction of the stirring rod 434, and then return under the action of the container wall to form a larger circulation loop. This circulation flow can make the enzyme preparation flow faster in the container, reduce the residence time of the material in the local area, thereby accelerating the overall mixing speed and improving the mixing efficiency.
[0038] It is also possible to mix the enzyme preparation around the mixing cylinder 1 .
[0039] Specifically, the intermediate mixer 5 includes a mixing shaft 51, an adjustment motor 52, a sliding block 53, an adjustment screw 54, two slide bars 55 and four adjustment blocks 56. A sliding groove 57 is provided at the middle position of the mixing shaft 51. The adjustment motor 52 is located in the driving shaft 24. The top of the adjustment screw 54 is connected to the main shaft of the adjustment motor 52. The bottom of the adjustment screw 54 is rotatably connected to the mixing shaft 51. The two slide bars 55 are symmetrically arranged in the sliding groove 35. The sliding block 53 is threadedly connected to the adjustment screw 54 and the sliding block 53 and the two slide bars 55 are slidably matched. Several of the adjustment blocks 56 are slidably connected to the two slide bars 55. A mutually hinged articulated rod group 59 is provided between the sliding block 53 and the four adjustment blocks 56; horizontally arranged mixing blade rods 58 are provided at both ends of the sliding block 53 and the four adjustment blocks 56.
[0040] When the enzyme preparation in the middle position of the mixing cylinder 1 is mixed, the rotation of the driving plate 23 will drive the mixing shaft 51 to rotate, thereby driving the plurality of mixing blade rods 58 to rotate, and the enzyme preparation in the middle position of the mixing cylinder 1 is mixed. While mixing, the adjusting motor 52 drives the adjusting screw rod 54 to rotate, which drives the sliding block 53 to move on the two sliding rods 55. The position movement of the sliding block 53 can drive the positions of the four adjusting blocks 56 to slide on the two sliding rods 55 through the hinged rod group 59, thereby adjusting the spacing and distance between the sliding block 53 and the four adjusting blocks 56. When the spacing and distance between the sliding block 53 and the four adjusting blocks 56 are adjusted, the spacing of the corresponding mixing blade rods 58 will be driven to be adjusted. Advantages of being able to adjust the pitch and distance of the mixing blade bars 58 used for mixing when mixing enzyme preparations: Improve uniformity: By adjusting the spacing and distance between the blade rods, the enzyme preparation can be subjected to more uniform shearing and stirring during the mixing process. Smaller spacing and appropriate distance allow the material to fully flow and exchange between the mixing blade rods 58, reducing local concentration differences, thereby improving the uniformity of mixing and ensuring that the enzyme preparation is evenly distributed throughout the system, which is beneficial to the consistency and stability of subsequent reactions.
[0041] Reduce mixing dead angles: Reasonably adjusting the spacing and distance can enable the mixing blade rod 58 to cover a larger space range, ensuring that the enzyme preparations in all parts of the container can be fully stirred. The position of the blade rod can be flexibly adjusted according to the shape and size of the container and the characteristics of the enzyme preparation, effectively eliminating mixing dead angles and avoiding insufficient mixing in some areas.
[0042] Enhance material flow: Appropriately increasing the spacing of the mixing blade rod 58 and adjusting the distance can form a smoother flow channel for the material during the mixing process, reducing the flow resistance and improving the overall fluidity of the material. In this way, the enzyme preparation can circulate more quickly in the container, increasing the collision and exchange frequency between materials, thereby shortening the mixing time and improving the mixing efficiency.
[0043] Specifically, there are three feeding ports 12, and the three feeding ports 12 are equally spaced on the cylinder cover 11. The three feeding ports 12 can respectively transport liquid enzyme preparations and other liquids into the mixing cylinder 1 for mixing work.
[0044] When mixing the enzyme preparation in the mixing cylinder 1, it is possible to mix the enzyme preparation in the middle position of the mixing cylinder 1 while also mixing the enzyme preparation around the mixing cylinder 1; It can eliminate concentration differences: The distribution of the enzyme preparation in the mixing cylinder 1 is often uneven, and the concentrations of the enzyme preparation in the middle position and the surrounding position may be different. Mixing these two areas simultaneously can enable the enzyme preparations with different concentrations to fully exchange and fuse, effectively eliminating the concentration gradient and ensuring that the concentration of the enzyme preparation in the entire cylinder is uniform, thereby improving the stability of the product quality.
[0045] Avoid local overmixing or undermixing: If only focusing on the mixing of the middle position or the surrounding position, it is easy to cause overmixing or undermixing in the other area. Mixing the two areas simultaneously can evenly apply the mixing effect to the enzyme preparation in the entire cylinder, avoiding the destruction of the enzyme activity due to excessive stirring in a local area or insufficient mixing due to insufficient stirring.
[0046] Promote mass exchange: During the mixing process, there is mass exchange between the enzyme preparation in the middle position and the surrounding position. Mixing these two areas simultaneously can accelerate the transfer and diffusion of substances, enabling the various components in the enzyme preparation to reach a uniform distribution more quickly. For example, for an enzyme preparation system containing multiple enzymes or additives, this mixing method helps the different components to interact better with each other and exert a synergistic effect.
[0047] Improving the reaction rate: Uniform mixing can make the contact between the enzyme preparation and the substrate more sufficient, increase the collision frequency between the enzyme and the substrate, and thus accelerate the reaction rate. For some enzyme preparations that need to react during the mixing process, such as enzymatic hydrolysis reactions, etc., simultaneously mixing the enzyme preparations at the middle position and the peripheral position can provide more favorable conditions for the reaction, improving the reaction efficiency and conversion rate.
[0048] The above are only embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention.
