Description

Technical Field

[0001] This invention relates to the field of adjunctive drugs for the treatment of diabetes, specifically to a method and apparatus for preparing a composition that helps control carbohydrate absorption. Background Technology

[0002] Currently, functional meal replacement foods are receiving widespread attention in areas such as weight management, blood sugar control, and adjunctive diabetes treatment. To achieve the effects of fat reduction or blood sugar control, naturally derived enzyme inhibitors are often added to meal replacement products, such as white kidney bean extract, mulberry leaf extract, and amla extract. These ingredients can reduce the breakdown and absorption of carbohydrates by inhibiting the activity of digestive enzymes such as amylase and sucrase, thereby delaying the rise in blood sugar and promoting fat metabolism.

[0003] However, existing natural enzyme inhibitors generally suffer from poor stability of active ingredients and low bioavailability when used orally. Due to the strong acidity of the gastric environment, polyphenols, flavonoids, or organic acids in some plant extracts are easily destroyed, resulting in a significant decrease in the content of effective ingredients after entering the intestines, making it difficult to exert the expected functional effects. In addition, to obtain significant metabolic regulatory effects, high doses of a single active ingredient are often required, which not only increases the cost of formulation but may also introduce problems related to taste, stability, and compatibility.

[0004] On the other hand, in the production of high-protein meal replacement bars or similar solid foods, powdered raw materials (such as protein powder, plant extract powder, dietary fiber, etc.) are prone to large differences in particle size, density, agglomeration, or uneven mixing due to layering. Traditional V-type mixers or two-dimensional stirring devices mainly rely on overall tumbling or rotational motion during the mixing process, often resulting in a laminar flow state of the material inside the cylinder, making it difficult to achieve thorough micro-mixing. Extending the mixing time not only increases energy consumption but may also cause some components to become damp or change their adsorption properties, affecting the stability of product quality.

[0005] Therefore, there is an urgent need for a composition preparation method that can improve the stability of natural active ingredients and enhance their site-specific release characteristics in the intestine, and to combine it with an equipment structure that provides higher mixing uniformity, so as to improve the overall quality and production efficiency of functional meal replacement foods.

[0006] Therefore, a method and apparatus for preparing a composition that helps control carbohydrate absorption are provided to address the above-mentioned problems. Summary of the Invention

[0007] This invention addresses the problems of existing natural enzyme inhibitors being easily destroyed by gastric acid during oral administration, resulting in poor stability of active ingredients, low bioavailability, and the need for high doses, which increases costs and affects taste and compatibility. Meanwhile, traditional mixing equipment is prone to problems such as powder layering and agglomeration in the preparation of meal replacement bar raw materials, leading to uneven mixing, high energy consumption, and difficulty in ensuring stable product quality. Therefore, this invention provides a method and equipment for preparing a composition that helps control carbohydrate absorption.

[0008] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a preparation device for a composition that helps control carbohydrate absorption, comprising a body, a mixing cylinder on one side of the body, and Y-shaped support arms clamped on both sides of the outer wall of the mixing cylinder. Both ends of the support arms are rotatably connected to the outer wall of the mixing cylinder, and the other end of the support arms is rotatably connected to a self-rotating drive shaft. The two ends of the mixing cylinder are respectively provided with a discharge port and a feed port. When the mixer stops, the feed port is tilted downward. An auxiliary mixing component is disposed inside a mixing cylinder and includes a guide support rod mounted on the inner wall of the mixing cylinder. An auxiliary mixing part is slidably connected to the guide support rod. The guide support rod is distributed along the axial direction of the mixing cylinder and coincides with the central axis of the mixing cylinder. The auxiliary mixing part is driven by the moving mixing cylinder and slides along the guide support rod under the action of gravity.

[0009] Specifically, the auxiliary mixing section includes a sliding unit that is slidably sleeved on the surface of the guide support rod. The sliding component includes a sliding component and a movable block sleeved on the surface of the sliding component for counterweight. The movable block has a ring structure, and multiple mixing units distributed in a ring array are arranged on the surface of the movable block.

[0010] The sliding unit includes a sliding ring, which is slidably sleeved on the surface of the guide bearing rod. A sliding sleeve is fixedly sleeved on the outer wall of the sliding ring, and a fixed moving block is sleeved at the center of the outer wall of the sliding sleeve.

[0011] In this application, protective telescopic bladders are provided at both ends of the sliding sleeve. The protective telescopic bladders wrap around the surface of the guide support rod. One end of the protective telescopic bladder is fixed to the annular side wall of the sliding sleeve, and the other end is fixed to the connecting cylinder at the end of the guide support rod. The connecting cylinder is sleeved and fixed to the end surface of the guide support rod.

[0012] In this application, the protective telescopic bladder is composed of multiple bladder units connected to each other. Each bladder unit includes a first connecting layer and a second connecting layer. Both the first connecting layer and the second connecting layer are frustum-shaped structures. The larger sidewalls of the first connecting layer and the second connecting layer are connected to each other. The surface area of ​​the second connecting layer is smaller than that of the first connecting layer. The second connecting layer is located on the side closer to the discharge port. Adjacent capsule units are connected to each other via connecting rings.

[0013] The soft structure at the connection points of the first connecting layer, the second connecting layer and the connecting ring, as well as at the connection points of the first connecting layer and the second connecting layer, can be achieved by reducing the thickness of the connection points.

[0014] Preferably, a guide portion is added to the connecting ring body to maintain the stability of the protective telescopic bladder during the telescopic process. The guide portion includes a guide ring, which is slidably sleeved on the guide support rod. The guide ring is fixedly connected to the corresponding connecting ring body through a plurality of fixed rods distributed in a ring array.

[0015] In this application, a buffer telescopic rod is fixed on the annular surface of the guide ring, a buffer spring is sleeved on the surface of the buffer telescopic rod, and the two ends of the buffer spring are respectively fixed to the two ends of the buffer telescopic rod. The end of the buffer telescopic rod can overlap with the surface of the adjacent guide ring.

[0016] The buffer telescopic rod and the buffer spring on its surface prevent the first and second connecting layers from completely adhering, ensuring that the distance between the first and second connecting layers is large enough after full contraction to prevent powder from being trapped.

[0017] Preferably, each connecting ring is provided with a guide portion to ensure that the expansion and contraction of each bladder unit can be controlled during the expansion and contraction of the telescopic bladder, and at the same time, it can play a buffering role when the moving block moves.

[0018] The mixing unit is one of the first mixing blade, the second mixing blade, and the third mixing blade, and the surface of the mixing unit is provided with a through groove.

[0019] The second mixing blade includes a first mixing plate and a second mixing plate. The first mixing plate is radially distributed along the mixing cylinder and fixed on the moving block. The second mixing plate is fixed at the end of the first mixing plate. The second mixing plate is bent toward the feed inlet or discharge outlet to form a curved structure. The cross-section of the first mixing plate and the second mixing plate is a "V" shaped structure. The first mixing plate has multiple evenly distributed second through slots.

[0020] The second mixing plates on two adjacent second mixing blades bend in opposite directions.

[0021] The first mixing plate is arranged radially along the cylinder and fixed on the moving block, serving as the main support and radial guide.

[0022] The third mixing blade includes a first shovel plate that is radially distributed along the mixing cylinder and fixed on the moving block. The end of the first shovel plate is bent toward the feed inlet or discharge outlet to form a curved and raised second shovel plate. The first and second shovel plates are recessed toward the side opposite to the bending direction of the second shovel plate to form an inward curved surface structure. The first and second shovel plates are provided with a third through groove that is interconnected. The first and second shovel plates are relatively wide.

[0023] A method for preparing a composition that helps control carbohydrate absorption, characterized by comprising the following steps: (1) Dissolve amla concentrate and sugarcane polyphenols in deionized water to prepare amla-sugarcane polyphenol aqueous solution; (2) Mix the amla-sugarcane polyphenol aqueous solution with chitosan nanoparticles at a mass ratio of 1:10 and stir at room temperature for 2 hours; (3) High-speed centrifugation was performed at a speed of 10,000 rpm, a time of 20 minutes, and a temperature of 4°C to obtain the precipitate; (4) The precipitate was freeze-dried at -80°C for 12 hours and then vacuum-dried for 24 hours to obtain dried amla-sugarcane polyphenol-encapsulated particles. (5) Dissolve white kidney bean extract, mulberry leaf extract and L-arabinose in deionized water to prepare a compound aqueous solution; (6) Mix the compound aqueous solution with chitosan nanoparticles at a mass ratio of 1:10 and stir at room temperature for 2 hours; (7) High-speed centrifugation was performed at a speed of 10,000 rpm for 20 minutes and a temperature of 4°C to obtain the precipitate; (8) The precipitate was freeze-dried at -80°C for 12 hours and then vacuum-dried for 24 hours to obtain dried white kidney bean extract-mulberry leaf extract-L-arabinose encapsulated particles. (9) Mix the amla-sugarcane polyphenol-encapsulated particles with white kidney bean extract-mulberry leaf extract-L-arabinose-encapsulated particles in a certain proportion to obtain a mixture of compositions; (10) Boil the sugar-free syrup to 105°C and keep it warm, then add the oil and homogenize; (11) The protein powder, dietary fiber powder and the composition mixture are mixed evenly in a three-dimensional mixer to make a premixed powder; (12) Heat the jacketed kettle to 55±5℃, pour in the premixed powder, add the sugar-oil mixture obtained in step (10), and stir into a uniform paste; (13) Sprinkle in the protein particles, stir evenly, cut into protein bars of equal weight, and package them.

[0024] Preferably, the protein bar formula is as follows: 8-35% protein powder, 5-10% oil, 20-38% sugar-free syrup, 10-40% protein particles, 10-20% dietary fiber, and 6-8% mixture of components.

[0025] Preferably, the dosage of the mixture is: 0.4g of mulberry leaf extract, 1.0g of amla concentrate powder, 0.5g of L-arabinose, 0.8g of white kidney bean powder and 0.5g of sugarcane polyphenols.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0027] The positive and progressive effects of this invention are as follows: The composition prepared by this method includes: amla concentrate, white kidney bean extract, L-arabinose, mulberry leaf extract, and sugarcane polyphenols. The preparation method involves encapsulating the amla concentrate, white kidney bean extract, and mulberry leaf extract with polysaccharides to improve the stability of the active ingredients, reduce the damage of gastric acid to the effective components, and achieve targeted release of the effective components in the intestine through pH-controlled release, solving the problem of low bioavailability of orally administered natural enzyme inhibitors due to gastric acid interference. This composition reduces the amount of monomers used and lowers raw material costs by leveraging the synergistic effect of each active ingredient. Applying this composition to high-protein meal replacement bars promotes the ketogenic response and can further promote the reduction of body fat. This composition, by leveraging the synergistic effect of each active ingredient, reduces the amount of monomers used and lowers raw material costs. Applying this composition to high-protein meal replacement bars promotes the ketogenic response and can further promote the reduction of body fat, and can be used for the treatment of diabetes.

[0028] In the preparation equipment, especially the three-dimensional mixer, an auxiliary mixing part is set inside the mixing cylinder of the three-dimensional mixer. This part is driven to move synchronously during the movement of the mixing cylinder and slides back and forth along the guide support rod under the action of gravity, thereby introducing additional local disturbance and shearing effect on the basis of three-dimensional mixing.

[0029] This effectively breaks the laminar or agglomerated state of powdered raw materials within the cylinder, allowing materials of different particle sizes and densities to undergo more thorough tumbling, dispersion, and mixing in space.

[0030] This structure not only improves the uniformity and stability of material mixing, but also significantly shortens the mixing time and improves the overall mixing efficiency without significantly increasing energy consumption. Attached Figure Description

[0033] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments. Example 1

[0034] A method for preparing a composition that helps control carbohydrate absorption, characterized by comprising the following steps: (1) Dissolve amla concentrate and sugarcane polyphenols in deionized water to prepare amla-sugarcane polyphenol aqueous solution; (2) Mix the amla-sugarcane polyphenol aqueous solution with chitosan nanoparticles at a mass ratio of 1:10 and stir at room temperature for 2 hours; (3) High-speed centrifugation was performed at a speed of 10,000 rpm, a time of 20 minutes, and a temperature of 4°C to obtain the precipitate; (4) The precipitate was freeze-dried at -80°C for 12 hours and then vacuum-dried for 24 hours to obtain dried amla-sugarcane polyphenol-encapsulated particles. (5) Dissolve white kidney bean extract, mulberry leaf extract and L-arabinose in deionized water to prepare a compound aqueous solution; (6) Mix the compound aqueous solution with chitosan nanoparticles at a mass ratio of 1:10 and stir at room temperature for 2 hours; (7) High-speed centrifugation was performed at a speed of 10,000 rpm for 20 minutes and a temperature of 4°C to obtain the precipitate; (8) The precipitate was freeze-dried at -80°C for 12 hours and then vacuum-dried for 24 hours to obtain dried white kidney bean extract-mulberry leaf extract-L-arabinose encapsulated particles. (9) Mix the amla-sugarcane polyphenol-encapsulated particles with white kidney bean extract-mulberry leaf extract-L-arabinose-encapsulated particles in a certain proportion to obtain a mixture of compositions; (10) Boil the sugar-free syrup to 105°C and keep it warm, then add the oil and homogenize; (11) The protein powder, dietary fiber powder and the composition mixture are mixed evenly in a three-dimensional mixer to make a premixed powder; (12) Heat the jacketed kettle to 55±5℃, pour in the premixed powder, add the sugar-oil mixture obtained in step (10), and stir into a uniform paste; (13) Sprinkle in the protein particles, stir evenly, cut into protein bars of equal weight, and package them.

[0035] The formula for protein bars is as follows: 8-35% protein powder, 5-10% fat, 20-38% sugar-free syrup, 10-40% protein particles, 10-20% dietary fiber, and 6-8% compound mixture.

[0036] The dosage of the mixture is as follows: 0.4g of mulberry leaf extract, 1.0g of amla concentrate powder, 0.5g of L-arabinose, 0.8g of white kidney bean powder and 0.5g of sugarcane polyphenols.

[0037] like Figure 16 As shown, the principle of the composition is as follows: Carbohydrates available to the human body include starch, disaccharides, and monosaccharides. Starch and disaccharides need to be converted into monosaccharides by digestive enzymes in the mouth and small intestine before they can be digested and absorbed by the body. Glucose and galactose enter intestinal epithelial cells against their concentration gradient via the sodium-glucose cotransporter 1 (SGLT1) and are then transported into the bloodstream via the GLUT2 transporter for use by the body. This invention utilizes functional components to inhibit different enzyme substrates, sites, and absorption pathways of carbohydrate absorption, thereby more effectively blocking carbohydrate absorption. Specifically: white kidney bean extract contains α-amylase inhibitors, which block 60% of starch enzymatic hydrolysis by inhibiting α-amylase activity; mulberry leaf extract and amla concentrate contain α-glucosidase inhibitors, so most of the sugars produced from the remaining enzymatically hydrolyzed starch cannot be converted into glucose; L-arabinose contains sucrase inhibitors, so most sucrose cannot be enzymatically hydrolyzed and utilized; only a small amount of starch and disaccharides can be successfully hydrolyzed to produce monosaccharides, but sugarcane polyphenols can inhibit the expression of transport proteins SGL1 and GLUT2. Under the action of sugarcane polyphenols, monosaccharides cannot be transported to the intestine via the SGLT1 transport protein or cannot be recycled via the GLUT2 transporter. Example 2

[0038] like Figure 1 and Figure 3As shown, a preparation device for a composition that helps control carbohydrate absorption includes a body 1, a mixing cylinder 2 on one side of the body 1, and Y-shaped support arms 3 on both sides of the outer wall of the mixing cylinder 2. Both ends of the support arms 3 are rotatably connected to the outer wall of the mixing cylinder 2, and the other end of the support arms 3 is rotatably connected to a self-rotating drive shaft 4. The two ends of the mixing cylinder 2 are respectively provided with a discharge port 22 and a feed port 21. When the mixer stops, the feed port 21 is tilted downward. An auxiliary mixing component 5 is disposed inside the mixing cylinder 2. The auxiliary mixing component 5 includes a guide support rod 51 installed on the inner wall of the mixing cylinder 2. An auxiliary mixing part is slidably connected to the guide support rod 51. The guide support rod 51 is distributed along the axial direction of the mixing cylinder 2 and coincides with the central axis of the mixing cylinder 2. The auxiliary mixing part is driven by the moving mixing cylinder 2 and slides along the guide support rod 51 under the action of gravity.

[0039] The auxiliary mixing section is driven by the moving mixing cylinder 2 and slides along the guide support rod 51 under the action of gravity, thereby improving the mixing effect.

[0040] like Figure 6 As shown, a connecting plate 511 is fixed to the end of the guide support rod 51, and the connecting plate 511 is fixed to the inner wall of the mixing cylinder 2 by an "L"-shaped connecting rod 512.

[0041] Specifically, such as Figures 4-6 As shown, the auxiliary mixing section includes a sliding unit that is slidably sleeved on the surface of the guide support rod 51. The sliding member includes a sliding member and a moving block 53 sleeved on the surface of the sliding member for counterweight. The moving block 53 has a ring structure, and multiple mixing units arranged in a ring array are provided on the surface of the moving block 53.

[0042] The sliding unit includes a sliding ring 532, which is slidably sleeved on the surface of the guide support rod 51. A sliding sleeve 531 is sleeved and fixed on the outer wall of the sliding ring 532, and a fixed moving block 53 is sleeved and fixed at the center of the outer wall of the sliding sleeve 531.

[0043] Preferred, such as Figures 9-11 As shown, both ends of the sliding sleeve 531 are provided with protective telescopic bladders 54. The protective telescopic bladders 54 wrap around the surface of the guide support rod 51, and one end of the protective telescopic bladder 54 is fixed to the annular side wall of the sliding sleeve 531, and the other end is fixed to the connecting cylinder 52 on the corresponding end of the guide support rod 51. The connecting cylinder 52 is sleeved and fixed to the end surface of the guide support rod 51. That is, the area of ​​the guide support rod 51 except for the two ends is wrapped by the two protective telescopic bladders 54, the two connecting cylinders 52 and the sliding sleeve 531, so as to prevent powder from entering the sliding connection between the sliding unit and the guide support rod 51 during stirring.

[0044] The protective telescopic bladder 54 is composed of multiple bladder units connected to each other. Each bladder unit includes a first connecting layer 541 and a second connecting layer 542. Both the first connecting layer 541 and the second connecting layer 542 are frustum-shaped structures. The larger sidewalls of the first connecting layer 541 and the second connecting layer 542 are connected to each other. The surface area of ​​the second connecting layer 542 is smaller than that of the first connecting layer 541. The second connecting layer 542 is located on the side closer to the discharge port 22. Adjacent capsule units are connected to each other through a connecting ring 543, that is, the second connecting layer 542 of the previous capsule unit is connected to the first connecting layer 541 of the next capsule unit through the connecting ring 543.

[0045] The connection points of the first connecting layer 541, the second connecting layer 542 and the connecting ring 543, as well as the connection points of the first connecting layer 541 and the second connecting layer 542, are soft structures. When the protective telescopic bladder 54 extends or shortens, the first connecting layer 541 and the second connecting layer 542 rotate relative to each other, and the connection points of the first connecting layer 541, the second connecting layer 542 and the connecting ring 543 rotate, thereby enabling the first connecting layer 541 and the second connecting layer 542 to approach or move away from each other.

[0046] When the moving block 53 slides completely to the limit position of one end of the guide support rod 51, the protective telescopic bladder 54 on that side is in a contracted state. The first connecting layer 541 and the second connecting layer 542 approach each other to the limit position. Since the surface area of ​​the second connecting layer 542 is smaller than the surface area of ​​the first connecting layer 541, the bladder unit in the contracted state has an umbrella-shaped structure, avoiding the residue of powdery raw materials in the gap between two adjacent bladder units.

[0047] The protective telescopic bladder 54 on the other side is in an extended state, and the bladder unit forms an asymmetrical gong-shaped structure.

[0048] The soft structure at the connection points of the first connecting layer 541, the second connecting layer 542 and the connecting ring 543, as well as at the connection points of the first connecting layer 541 and the second connecting layer 542, can be achieved by reducing the thickness of the connection points.

[0049] Preferably, a guide portion 55 is added at the connecting ring body 543 to maintain the stability of the protective telescopic bladder 54 during the telescopic process. The guide portion 55 includes a guide ring 551, which is slidably sleeved on the guide support rod 51. The guide ring 551 is fixedly connected to the corresponding connecting ring body 543 through a plurality of fixed rods 552 distributed in a ring array.

[0050] A buffer telescopic rod 553 is fixed on the annular surface of the guide ring 551. A buffer spring is sleeved on the surface of the buffer telescopic rod 553, and the two ends of the buffer spring are respectively fixed to the two ends of the buffer telescopic rod 553. The end of the buffer telescopic rod 553 can overlap with the surface of the adjacent guide ring 551.

[0051] The buffer telescopic rod 553 and the buffer spring on the surface of the buffer telescopic rod 553 can prevent the first connecting layer 541 and the second connecting layer 542 from being completely adhered together, so that the distance between the first connecting layer 541 and the second connecting layer 542 after complete shrinkage is large enough to avoid powder from being trapped.

[0052] When the moving block 53 moves to the limit position of one end of the guide bearing rod 51, the buffer telescopic rod 553 on the guide ring 551 will contact the surface of the adjacent guide ring 551, and the buffer telescopic rod 553 will retract. The buffer spring can play a buffering role. At the same time, when the material is discharged, the protective telescopic bladder 54 on the side near the discharge port 22 will fully retract. The buffer spring will prevent the buffer telescopic rod 553 from retracting or from fully retracting, so that the distance between the first connecting layer 541 and the second connecting layer 542 after full retraction is large enough to avoid powder from being mixed in.

[0053] Preferably, each connecting ring is provided with a guide portion 55 so as to protect the telescopic bladder 54 during telescopic movement, and the extension and contraction of each bladder unit can be controlled. At the same time, it can play a buffering role when the moving block 53 moves.

[0054] like Figure 7 and Figure 8 As shown, the mixing unit is one of the first mixing blade 56, the second mixing blade 57 and the third mixing blade 58, and the surface of the mixing unit is provided with a through groove.

[0055] The first hybrid blade 56 includes two C-shaped hybrid blades 561 connected end to end, and the two C-shaped hybrid blades 561 are centrally symmetrically distributed with a symmetry angle of 180°.

[0056] The surfaces of the two C-shaped mixing plates 561 are provided with first through grooves 562, and the two C-shaped mixing plates 561 form a wave-like structure. One of the C-shaped mixing plates 561 is fixed on the moving block 53.

[0057] When the first mixing blade 56 moves on the guide rod, it forms a non-planar curved motion trajectory, which is different from the single shearing or pushing effect of traditional straight blades. In the three-dimensional motion of the cylinder rotation and translation superposition, the wavy surface will periodically change the contact angle and direction with the powder, forming multi-directional tumbling, so that the powder generates a complex "flow folding" path in the cylinder, improving the overall mixing uniformity.

[0058] In this embodiment, the first mixing blade 56 has a variable direction of material turning and gentle disturbance; it can achieve good uniformity at low speed; the sliding vibration brings periodic disturbance, which is suitable for powders with fine particle size and small density difference.

[0059] like Figure 12 and Figure 13 As shown, the second mixing blade 57 includes a first mixing plate 571 and a second mixing plate 572. The first mixing plate 571 is radially distributed along the mixing cylinder 2 and fixed on the moving block 53. The second mixing plate 572 is fixed at the end of the first mixing plate 571. The second mixing plate 572 is bent toward the feed inlet 21 or the discharge outlet 22 to form a curved structure. The cross-section of the first mixing plate 571 and the second mixing plate 572 is a "V" shaped structure. The first mixing plate 571 has a plurality of evenly distributed second through slots 573.

[0060] The second mixing plates 572 on two adjacent second mixing blades 57 bend in opposite directions.

[0061] The first mixing plate 571 is arranged radially along the cylinder and fixed on the moving block 53, serving as the main support and radial guide.

[0062] The "V" shaped cross-section means that there are two inclined surfaces on the blade surface, which can form an alternating effect of diversion and concentration flow, so that the powder particles are constantly broken up and recombined.

[0063] When the cylinder undergoes three-dimensional composite motion, the raised end will have an upward throwing and guiding effect on the powder, forming a significant vertical tumbling flow.

[0064] The opposite bending directions of adjacent blades cause the powder flow inside the cylinder to reverse periodically, thus forming a bidirectional circulating flow field (forward + reverse), which greatly improves the mixing uniformity.

[0065] In this embodiment, the second blade has strong vertical agitation and fast mixing speed; cross-flow prevents segregation; it is suitable for medium-flow powders and applicable to mixing systems with large density differences or easy stratification.

[0066] like Figure 14 and Figure 15 As shown, the third mixing blade 58 includes a first shovel plate 581 that is radially distributed along the mixing cylinder 2 and fixed on the moving block 53. The end of the first shovel plate 581 is bent toward one side of the feed inlet 21 or the discharge outlet 22 to form a curved and raised second shovel plate 582. The first shovel plate 581 and the second shovel plate 582 are recessed toward the side opposite to the bending direction of the second shovel plate 582 to form an inward curved surface structure. The first shovel plate 581 and the second shovel plate 582 are provided with a third through groove 583 that communicates with each other. The first shovel plate 581 and the second shovel plate 582 are relatively wide.

[0067] The second shovels 582 on the two adjacent third mixing blades 58 bend in opposite directions.

[0068] The concave curved surface, or recessed arc structure, improves streamline distribution, creating a convergence and guiding effect. The wide blade surface, under the three-dimensional motion of the cylinder, can lift a larger volume of powder at once, enhancing the overall tumbling and displacement distance of the powder, and significantly improving convective mixing efficiency. The raised second shovel plate 582 throws the powder upwards along the length of the cylinder, causing it to fall back down under gravity, forming a stable "throw-fall-tumble" circulating flow field.

[0069] In this embodiment, the third blade has a large agitation and a wide coverage area; it has significant effects in preventing dead corners and compaction.

[0070] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
