Description

Technical Field

[0001] This invention relates to the technical field of grinding equipment, and more particularly to a household gluten-free flour mill and a method for preparing gluten-free chiffon cake premix. Background Technology

[0002] Gluten-free chiffon cake premix is ​​based on various refined gluten-free flours. The raw materials are ground to produce qualified flours, which are the basic raw materials for blending premixes. Gluten-free flour raw materials are whole grains, which need to be ground into flour using grinding equipment. Individual households usually choose small household equipment for home processing, which requires less investment and space, and is suitable for orders and small-batch production and sales needs in the surrounding residential areas.

[0003] However, in existing technologies, the grinding components require continuous mechanical energy transmission to generate high-speed extrusion that impacts and rubs against the material, leading to increased temperatures in the grinding discs and chamber. Furthermore, to ensure effective grinding and prevent leakage of the powder due to gaps, the equipment chamber must be sealed and components tightly fitted, limiting natural heat dissipation and causing heat accumulation that is difficult to eliminate. Additionally, the inherent oils in legumes and nuts release internal heat during particle deformation. This multiple heat sources combined cause the powder and grinding chamber to overheat rapidly, resulting in premature and abnormal gelatinization of the starch within the raw materials. This causes the powder to clump together and adhere to the grinding chamber and screen surface, easily clogging the screening system and altering the inherent water absorption properties of the starch. Gluten-free powders, lacking gluten structure, rely solely on... The use of colloids such as xanthan gum for binding disrupts the water absorption balance during the kneading stage, causing the batter to soften and collapse. This accelerates the oxidation and deterioration of unsaturated fatty acids in the powder, affecting not only the quality of subsequent chiffon cakes and pastries but also significantly shortening the shelf life of the finished product. Furthermore, the high temperature causes the plant proteins in the raw materials to coagulate and denature, resulting in the loss of the powder's original weak binding ability. Even with the addition of baking improvers, the problem of poor gas retention cannot be solved, leading to a dense, solid interior that is prone to collapse and shrinkage after baking. At the same time, the high temperature also damages the vitamins and heat-sensitive amino acids in the raw materials, resulting in a loss of the flour's nutritional value. In addition, the high temperature makes the powder prone to sticking to the walls and clogging the machine, causing frequent machine shutdowns for cleaning, disrupting the production rhythm, and requiring reprocessing and re-grinding of clumped materials, affecting quality, increasing the number of defective products, increasing raw material waste, and impacting production. Summary of the Invention

[0006] Furthermore, the moving disk is provided with a blade cone sleeve, and the surface of the moving disk is provided with a serration group, which includes long serrations and short serrations. The surface of the moving disk is provided with a plurality of honeycomb-shaped convex balls, and the number of long serrations is less than the number of short serrations.

[0007] Furthermore, the surface of the fixed plate is provided with multiple breaking teeth of different lengths. The density of the breaking teeth is greater than that of the saw tooth group, and the width of the saw tooth group is greater than that of the breaking teeth. The outer diameter of the moving plate gradually tilts towards the center of the moving plate, while the outer diameter of the fixed plate gradually tilts away from the center of the moving plate.

[0008] Furthermore, multiple copper blocks are equidistantly engaged on one side of the flow distribution plate near the flow guide plate. Multiple arc grooves are equidistantly formed on the copper blocks. A splicing pipe is located on one side of the middle of the flow distribution plate. One end of the splicing pipe extends to the other side of the return plate and has multiple flow holes equidistantly formed. At the same time, multiple flow guide rods are equidistantly arranged on this side of the flow distribution plate. The number of copper blocks and flow guide rods is equal. The copper blocks penetrate the flow guide rods and fit against the inner surface of the moving plate.

[0009] Furthermore, the outer diameter of the guide plate is sloping and multiple flow-dividing ports are opened at equal angles on the outer diameter. A flow-equalizing ring is provided on the side of the guide plate near the flow-dividing plate, and multiple flow-equalizing grooves are opened at equal angles on the flow-equalizing ring.

[0010] Furthermore, a sealing ring is provided on one side of the return plate near the flow divider plate, and the sealing ring fits with the flow guide plate to form an external flow channel. A return pipe is fixedly connected to the other side of the return plate. A straight groove is opened in the middle of the return plate, and the straight groove communicates with the return pipe. The middle of the flow divider plate communicates with the return pipe.

[0011] Furthermore, the flow divider is connected to the external flow channel formed by the sealing ring and the flow guide plate, the bottom of the copper block is set as a cone, the flow equalization ring is attached to the arc surface of multiple copper blocks, and the cone end of the copper block is located near the center of the flow divider plate.

[0012] Furthermore, the return pipe is provided with two scrapers and a brush plate on its exterior, and the water-cooled circulator is provided with a flow guide sleeve. One end of the return pipe is rotatably connected to the inside of the flow guide sleeve, one end of the delivery pipe is located inside the splicing pipe, and the other end of the delivery pipe passes through the flow guide sleeve and is fixedly connected to the water-cooled circulator.

[0013] Furthermore, a transmission device is provided at the top of the support, a rotating shaft is rotatably connected inside the machine head, a guide port is provided at the top of the machine head, the moving disc is engaged with one end of the rotating shaft, and the other end of the rotating shaft is rotatably connected to the transmission device.

[0014] This invention provides, in one aspect, a method for preparing gluten-free chiffon cake premix, applicable to a household gluten-free flour mill, comprising the following steps: Step 1: Prepare raw materials and remove impurities. Then, place the raw materials into the inside of the machine head and grind them through the fixed plate and moving plate. Various gluten-free fine powders are obtained through the side plate sieve.

[0015] Step 2: Mix the various gluten-free fine powders in the specified proportions, then mix them using a mixing device, adding different additives in sequence, and gradually adjusting the mixing speed from medium to high.

[0016] Step 3: After mixing, the mixture is broken up by vibrating a screen, then left to mature at room temperature, and finally sealed and packaged after quality inspection.

[0017] The beneficial effects of this invention are: Through the double-layer flow channel structure, the coolant is forced to circulate. The coolant is precisely delivered to the inside of the moving plate through the delivery pipe, and then evenly distributed by the distribution plate and guided by the guide plate to fully cover the crushing area of ​​the moving plate. After heat exchange, it is collected and circulated by the return plate. At the same time, the high thermal conductivity of copper is used to quickly absorb the heat generated by the moving plate. Combined with the dynamic heat exchange of the coolant, the problem of local heat accumulation and uneven heat exchange is eliminated, improving the processing quality of gluten-free powder and meeting the needs of household powder production.

[0018] The moving disc is equipped with staggered saw teeth of varying lengths and honeycomb-shaped protrusions. The long saw teeth preferentially split large grain particles, while the short saw teeth finely grind the material. The honeycomb protrusions increase the impact and kneading area of ​​the material, improving the crushing efficiency of hard grains and nuts. Meanwhile, the fixed disc has a higher density and narrower tooth width, forming a shearing and extrusion structure with the moving disc saw teeth, creating a multi-layer crushing effect on the material. At the same time, the moving and stationary discs form a gradual gap from the inside to the outside, allowing the material to be finely ground from the center to the outer edge, avoiding heat accumulation and agglomeration caused by excessive compression in a single operation, and ensuring the powder processing requirements are met.

[0019] By using a double-layer flow channel with a dedicated guide sleeve limiting structure, interference from pipeline rotation can be effectively avoided, friction during high-speed rotation can be reduced, and wear on components can be minimized. At the same time, the power structure consisting of the head, shaft and transmission unit is compact and the transmission is direct and stable. Combined with the centering structure of the moving disc blade cone sleeve, eccentric swaying during high-speed operation can be effectively avoided, ensuring uniform grinding gap, strong overall structural stability, and extending the service life of equipment components. It is suitable for long-term, high-frequency use in home environments. Attached Figure Description

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, refer to Figures 1-12 The first embodiment of the present invention provides a household gluten-free flour mill, including a support frame 1, a mill head 2 and a water-cooled circulator 3 fixedly connected to the top of the support frame 1, a fixed plate 4 fixedly connected to the mill head 2, a moving plate 5 rotatably connected to the mill head 2, a diverting plate 6 disposed inside the moving plate 5, a guide plate 7 snapped onto one side of the diverting plate 6, a return plate 8 snapped onto one side of the guide plate 7, a sealing plate 9 snapped onto the return plate 8, a copper ring 10 sleeved between the moving plate 5 and the guide plate 7, and a flow pipe 11 with one end sleeved inside the guide plate 7 and fixedly connected to the return plate 8. The return pipe 12, the side plate 13 which is snapped into the head 2, and the screen 14 and the guide sleeve 15 set between the head 2 and the side plate 13, the fixed plate 4 and the moving plate 5 have the same outer diameter and are concentric. The fixed plate 4 and the moving plate 5 are used for grinding. The guide plate 7 is located between the diversion plate 6 and the return plate 8. The conveying pipe 11 is located inside the return pipe 12. The water cooling circulator 3 is fixedly connected to the side plate 13. The guide sleeve 15 is located outside the screen 14. The coolant is diverted and circulated inside the moving plate 5 through the diversion plate 6 and the guide plate 7, and the coolant is collected and returned through the return plate 8.

[0024] Specifically, the distribution plate 6, guide plate 7, and return plate 8 are sequentially snapped together. Coolant is supplied by the water-cooled circulator 3 and delivered to the distribution plate 6 via the delivery pipe 11, completing the initial flow. Simultaneously, the structure on one side of the distribution plate 6 divides the coolant, dispersing it to the outer diameter of the distribution plate 6, thus uniformly dispersing it before flowing into the guide plate 7 on the other side. During equipment operation, the coolant is subjected to centrifugal force due to the rotation of the rotating plate 5, spreading outwards evenly. It is also mainly propelled by the continuous liquid flow circulation thrust from the rear delivery pipe 11, forming a stable and active forced flow effect. The coolant is then guided in two directions through the guide plate 7, ensuring that the coolant fully covers the area. The working area of ​​the moving plate 5 avoids heat accumulation inside the sealed cavity. After heat exchange, the coolant flows into the return plate 8 and is centrally returned through the return pipe 12, which is fixedly connected to the return plate 8. In addition, the flow pipe 11 is nested inside the return pipe 12, forming a double-layer flow channel structure with inner and outer pipes, realizing continuous circulation of coolant. The copper ring 10 is sleeved between the moving plate 5 and the guide plate 7. Utilizing the thermal conductivity of copper, the temperature at the outer diameter of the moving plate 5 is quickly conducted, and the heat is efficiently transferred to improve the heat exchange efficiency. The flow is distributed by the distribution plate 6, while the guide plate 7 guides the liquid throughout the entire area, and the liquid is centrally returned through the return plate 8 to achieve temperature control and effectively prevent the raw materials from deteriorating due to high temperature.

[0025] Reference Figures 1-6 The moving disk 5 is provided with a blade cone sleeve 51, and the surface of the moving disk 5 is provided with a serration group 52, which includes long serrations and short serrations. The surface of the moving disk 5 is provided with a plurality of honeycomb-shaped convex balls 53, and the number of long serrations is less than the number of short serrations.

[0026] The surface of the fixed plate 4 is provided with multiple breaking teeth 41 of different lengths. The density of the breaking teeth 41 is greater than that of the saw tooth group 52. The width of the saw tooth group 52 is greater than that of the breaking teeth 41. The outer diameter of the moving plate 5 gradually tilts towards the center of the moving plate 5, while the outer diameter of the fixed plate 4 gradually tilts away from the center of the moving plate 5.

[0027] Specifically, the fixed disc 4 and the moving disc 5 have the same outer diameter and are concentrically assembled. The moving disc 5 relies on high-speed relative motion to squeeze and pulverize gluten-free grains, nuts, and other raw materials through friction, ensuring fineness and processing efficiency. The blade cone sleeve 51 is connected to the head 2 for splicing and output power transmission, which can stabilize the high-speed rotation of the moving disc 5, improve the coaxiality of the moving disc 5 rotation, and avoid eccentric shaking during high-speed operation, ensuring uniform and stable grinding gap. It can also assist in guiding the feed material to cooperate with the head 2 for initial dispersion, and then allow the raw materials to enter the pulverizing area evenly, improving the uniformity of pulverization. In addition, the staggered sawtooth group 52 structure can realize graded pulverization. The long sawtooth prioritizes the initial splitting and crushing of large raw material particles, while the short sawtooth follows to finely grind the fine particles. Combined with the honeycomb convex balls 53, it can increase the friction of the disc surface, thereby increasing the impact area and strengthening the material kneading and pulverizing effect, effectively improving the pulverization efficiency of gluten-free grains, nuts, and hard raw materials. To avoid large particle residue, the crushing teeth 41 on the surface of the fixed disc 4 have a higher overall density than the sawtooth group 52 of the moving disc 5, and the width of the sawtooth group 52 is greater than the width of the crushing teeth 41. This creates a differentiated crushing structure where the moving disc 5 has wide teeth for coarse crushing, while the fixed disc 4 has dense teeth for fine grinding. This structure can create multi-layer extrusion and shearing on the material, generating an impact effect and improving the fineness of the powder. This is suitable for the high-precision processing requirements of gluten-free powders. At the same time, the moving disc 5 gradually tilts towards the fixed disc 4 from the center to the outer diameter, while the fixed disc 4 gradually tilts away from the moving disc 5 from the center to the outer diameter. This creates a wedge-shaped crushing gap that gradually changes from the inside to the outside between the two discs. The material can experience a gradual crushing gap from large to small as it moves from the central feeding area to the outer screening area, achieving progressive fine grinding of the material. This avoids the heat accumulation, gelatinization, and agglomeration caused by excessive single extrusion, ensuring that all powders are ground to a uniform fineness. Combined with water cooling, this further optimizes the processing quality of gluten-free powders.

[0028] Reference Figures 3-9 On one side of the distribution plate 6 near the guide plate 7, multiple copper blocks 61 are clamped at equal angles. Multiple arc grooves 611 are equally spaced on the copper blocks 61. On one side of the middle part of the distribution plate 6, there is a splicing pipe 62. One end of the splicing pipe 62 extends to the other side of the return plate 8 and multiple flow holes 621 are equally spaced to introduce coolant between the guide rods 63. At the same time, multiple guide rods 63 are equally spaced on this side of the distribution plate 6. The number of copper blocks 61 and guide rods 63 is equal. The copper blocks 61 penetrate the guide rods 63 and fit against the inner surface of the moving plate 5.

[0029] Specifically, when coolant is introduced between the guide rods 63, it is propelled by centrifugal force and the continuous influx of coolant, flowing along both sides of the guide rods 63 towards the outer diameter of the distribution plate 6. During the flow, the coolant cools the area in contact with the moving plate 5. Sufficient supporting force is needed to ensure the stable rotation of the moving plate 5, thus the guide rods 63 provide internal support and guide the flow. Therefore, the area where the guide rods 63 are located will cover part of the interior of the moving plate 5, preventing the coolant from cooling it. Furthermore, since the diameter of the distribution plate 6 is smaller than the diameter of the guide plate 7, and the end of the guide rod 63 furthest from the center of the distribution plate 6 coincides with the outer diameter of the guide plate 7, the coolant reaches the outer diameter of the distribution plate 6... The coolant will be diverted, with most of it entering between the guide plate 7 and the distribution plate 6, and some entering the return plate 8. At this time, the coolant between the guide plate 7 and the distribution plate 6 will pass through the copper block 61, which is installed through the corresponding guide rod 63, thus closely adhering to the inner surface of the moving plate 5. This ensures effective support and covers the uncooled area, efficiently absorbing the frictional and extrusion heat generated by the moving plate 5, achieving rapid heat transfer, and completing efficient heat exchange in conjunction with the coolant flow. At the same time, the regularly arranged arc grooves 611 can further divert and organize the flowing coolant, regulate the coolant flow trajectory, avoid the accumulation of coolant and the resulting turbulence, and ensure uniform coolant distribution.

[0030] Reference Figures 1-9 The outer diameter of the guide plate 7 is sloping and has multiple flow-dividing ports 701 at equal angles. A flow-equalizing ring 71 is provided on the side of the guide plate 7 near the flow-dividing plate 6. Multiple flow-equalizing grooves 711 are provided on the flow-equalizing ring 71 at equal angles. The bottom of the copper block 61 is set as conical. The flow-equalizing ring 71 fits into the arc surface of the multiple copper blocks 61 to form a stable support and ensure structural stability. The conical end of the copper block 61 is located near the center of the flow-dividing plate 6, matching the flow path of the coolant diffusing from the outer diameter to the inner diameter. After the heat is conducted from the inner wall of the moving plate 5 to the copper block 61, it comes into full contact with the flowing coolant, avoiding the problems of uneven local heat exchange and local heat accumulation.

[0031] Specifically, due to the diversion effect of the distribution plate 6, the coolant is divided into two parts. A large flow of coolant will reach between the distribution plate 6 and the guide plate 7, while some coolant will enter the return plate 8. This causes the coolant to not enter the distribution plate 6 and the guide plate 7 evenly from different directions. At this time, the sloped outer diameter structure of the guide plate 7 is used to guide the coolant, thereby adapting to the rotating flow trajectory of the coolant. At the same time, the flow equalization ring 71 intercepts the coolant, which can perform secondary regulation and equalization of the coolant flowing out of the distribution plate 6, further eliminating the water pressure difference and ensuring the uniformity of the coolant flow throughout the entire area. The coolant is distributed around the flow equalization ring 71. In addition, the flow equalization ring 71 has multiple guide slots 711 with equal angles, which can evenly disperse and discharge the coolant outward, allowing it to contact multiple copper blocks 61 to absorb heat.

[0032] Reference Figures 2-10 A sealing ring 81 is provided on one side of the return plate 8 near the distribution plate 6. The sealing ring 81 fits with the guide plate 7 to form an outer flow channel. A return pipe 82 is fixedly connected to the other side of the return plate 8. A straight groove 801 is opened in the middle of the return plate 8. The straight groove 801 is interconnected with the return pipe 82. The distribution port 701 is interconnected with the outer flow channel formed by the sealing ring 81 and the guide plate 7, so that the heat exchange coolant passing through the distribution port 701 can all flow into the outer flow channel and flow in the outer flow channel, and then come into contact with the continuous copper ring 10 to realize continuous circulation heat exchange of coolant. The straight groove 801 is interconnected with the internal cavity of the return pipe 82, so that the coolant gathered in the outer flow channel can be uniformly concentrated and quickly introduced into the return pipe 82 through the middle straight groove 801, completing the directional collection and transportation of coolant after heat exchange, and realizing continuous circulation heat exchange of coolant.

[0033] Reference Figures 1-12 The return pipe 12 is externally equipped with two scrapers 121 and a brush plate 122, which can rotate synchronously with the return pipe 12. This allows for real-time scraping and cleaning of fine powder and dust adhering to the internal cavity of the equipment, enabling the powder to quickly pass through the screen 14 and effectively preventing powder adhesion and accumulation. The water-cooled circulator 3 is equipped with a guide sleeve 31, with one end of the return pipe 12 rotatably connected inside the guide sleeve 31. The guide sleeve 31 limits and adapts the rotating end of the return pipe 12, effectively avoiding structural interference during rotation and ensuring the stability of the rotation operation. The conveying pipe 11... The end of the pipe 11 is installed inside the splicing pipe 62 to accurately deliver the coolant to the central water channel area of ​​the distribution plate 6. The other end of the pipe 11 passes through the guide sleeve 31 and is fixedly connected to the water cooling circulator 3, making the overall water delivery structure layout neat and the positioning firm. The guide sleeve 31 has a shaft structure inside, and the shaft and the end of the return pipe 12 are sleeved together to reduce the rotational friction generated during the high-speed rotation of the return pipe 12, effectively reducing the rotational wear of the components, improving the smoothness of the structure rotation, extending the service life of the pipeline and the supporting rotating components, and ensuring the long-term stable operation of the double-layer flow channel structure.

[0034] A transmission device 101 is installed on the top of the support 1. A rotating shaft 21 is rotatably connected inside the head 2. A material guide port 22 is installed on the top of the head 2. The moving disc 5 is engaged with one end of the rotating shaft 21. The other end of the rotating shaft 21 is rotatably connected to the transmission device 101. The moving disc 5 is connected to the head 2 through the rotating shaft 21, providing stable rotational power for grinding and pulverizing operations. The overall transmission structure is compact and the power transmission is direct, making it suitable for the operation needs of small household grinding equipment.

[0035] Specifically, a transmission device 101 is provided on the top of the support 1. The transmission device 101 can work with the installed drive motor to generate driving force and provide a power output source for the grinding operation of the equipment. The machine head 2 is fixedly connected to the top of the support 1, providing an integrated installation carrier.

[0036] The working principle of this invention is as follows: The motor driving force is received by the transmission device 101 at the top of the support 1. The power is coaxially transmitted to the blade cone sleeve 51 via the rotating shaft 21 inside the machine head 2, driving the moving disc 5 to rotate at high speed. The fixed disc 4 is fixed to the side of the machine head 2 and remains stationary. The raw material is fed into the center of the cavity from the guide port 22 at the top of the machine head 2. Under the action of the rotating guide and initial crushing of the blade cone sleeve 51, it falls evenly into the gap area between the two discs for secondary crushing. The crushed powder is discharged through the screen 14 and the guide sleeve 15. At the same time, the water-cooled circulator 3 outputs coolant, which is sent to the splicing pipe 62 in the middle of the distribution disc 6 through the conveying pipe 11. The coolant is dispersed to the gaps between the guide rods 63 through the flow holes 621 of the splicing pipe 62. As the moving disc 5 rotates... Under the combined action of centrifugal force and rear-end liquid replenishment thrust, the coolant diffuses along the guide rod 63 towards the outer edge of the distribution plate 6, absorbing heat from the moving plate 5. Simultaneously, the coolant reaches the outer diameter of the distribution plate 6 and is divided. Part of the medium enters the interlayer between the distribution plate 6 and the guide plate 7, flows along the slope of the guide plate 7, and after secondary equalization by the equalization ring 71, it contacts the copper block 61 and absorbs heat. Then, it gathers in the middle of the distribution plate 6 and enters the interconnected loop pipe 82. The other part of the medium is discharged through the distribution port 701 into the outer flow channel formed by the guide plate 7 and the sealing ring 81, contacts the copper ring 10 to flow the coolant for heat exchange, and then the coolant gathers from the outer flow channel to the straight groove port 801 in the middle of the return plate 8, enters the loop pipe 82, and after being collected, flows into the return pipe 12, returning to the water-cooled circulator 3 for cooling, completing the circulation.

[0037] Example 2, refer to Figures 1-12 The second embodiment of the present invention provides a method for preparing gluten-free chiffon cake premix powder, which is applied to a household gluten-free flour milling machine and includes the following steps: Step 1: Prepare raw materials and remove impurities. Then, place the raw materials into the inside of the machine head 2 and grind them through the fixed plate 4 and the moving plate 5. Then, sieve them through the side plate 13 to obtain various gluten-free fine powders.

[0038] Step 2: Mix the various gluten-free fine powders in the specified proportions, then mix them using a mixing device, adding different additives in sequence, and gradually adjusting the mixing speed from medium to high.

[0039] Step 3: After mixing, the mixture is broken up by vibrating a screen, then left to mature at room temperature, and finally sealed and packaged after quality inspection.
