Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and specifically relates to a water-flour mixing device for dough processing. Background Technology

[0002] Fully automatic dough mixers are a type of noodle-making machinery. Their main function is to evenly mix flour and water. They can also beat eggs and mix fillings. There are various types of dough mixers, including reversible precision dough mixers, simple dough mixers, dough mixers, high-power dough mixers, and dual-speed dual-action dough mixers. These machines are frequently used in enterprises, canteens, guesthouses, restaurants of all sizes, factories, schools, and military units. They are easy to operate and have high dough-making efficiency.

[0003] Chinese patent CN111657312B discloses a dough mixer, including a base, a head, a material container, a dough separating rod, and a dough hook. The head is positioned above the base; the material container is mounted on the base; a first mounting portion is provided at the end of the head; the dough separating rod is used to separate the dough in the material container, and has a second mounting portion that cooperates with the first mounting portion. The dough separating rod is slidably mounted downwards on the first mounting portion and can be detached upwards; the dough hook is used to stir the dough in the material container, and is connected below the head, and can be detached horizontally. This invention allows for easy detachment of the dough separating rod and the dough hook without lifting the machine head, facilitating disassembly and cleaning.

[0004] When kneading dough, yeast is usually added. The optimal fermentation temperature for yeast is 28-32℃. During the kneading process, the high-speed friction of the dough mixer generates heat. If the dough is not cooled, the temperature will exceed 35℃, causing the yeast to produce a large amount of gas prematurely. This makes the yeast "ineffective" during subsequent shaping and secondary fermentation, resulting in a coarse texture and an excessively sour taste in the finished product. Current technology usually adds ice cubes during kneading to achieve a cooling effect. However, when the ice cubes melt into water, it causes an uneven water-to-flour ratio in the dough, making the dough difficult to shape and affecting the kneading effect. Summary of the Invention

[0005] The purpose of this invention is to provide a water-flour mixing device for dough processing, which aims to solve the problem that existing dough mixers do not have the effect of cooling the dough, and that when ice is used to cool the dough, the melted water makes the dough difficult to shape.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flour mixing device for dough processing, comprising: a base, a kneading hook, and a machine head located on the base. A material cylinder is rotatably mounted on the base. The kneading hook is mounted on the machine head and located inside the material cylinder. A vertically downward column is provided on the machine head. A base is provided at the bottom of the column. A sleeve is rotatably connected to the base, and the sleeve is close to the inner wall of the material cylinder. The base is located below the sleeve. A top cover is provided above the sleeve. A sealed cavity is formed inside the sleeve.

[0007] The base includes a chassis and a partition. The partition is located inside the sleeve and can divide the cavity inside the sleeve into two mirror-symmetrical small cavities for adding cooling material. The column runs through the partition and the top cover and is detachably connected to the machine head.

[0008] A further technical solution of the present invention is that an installation groove is provided in the middle of the partition plate, and the column is rotatably set in the inner bottom of the installation groove so that the column can swing freely inside the installation groove. A notch is opened on the top cover, the column passes through the notch and can slide in the notch, and a connecting rod is hinged to the top cover at the diagonal of the column. A sliding plate is hinged to the end of the connecting rod away from the top cover. The sliding plate slides on the machine head, and a drive unit for driving the sliding plate is provided on the machine head.

[0009] A further technical solution of the present invention is that one side of the partition is inclined, so that the partition gradually moves away from the inner wall of the sleeve from top to bottom through the inclined surface, and the two small cavities inside the sleeve are connected to each other.

[0010] A further technical solution of the present invention is that the material cylinder includes an outer cylinder and an inner liner. The outer cylinder is fixed on the machine base, and the inner liner is rotatably disposed inside the outer cylinder. Multiple push blocks are arranged in a ring array inside the inner liner. An elastic element is provided on the inner liner. The push blocks can protrude into the interior of the inner liner under the action of the elastic element. When the push blocks are retracted between the inner liner and the outer cylinder, the push blocks are flush with the inner wall of the inner liner. A magnetic element is provided on one side of the outer cylinder located on the sleeve to attract the push blocks and overcome the elastic element retracting into the space between the inner liner and the outer cylinder.

[0011] A further technical solution of the present invention is that a second rotating shaft is provided on the machine head, and the dough hook is connected to the second rotating shaft through a universal joint. A bent pipe is fixedly connected to the lower part of the machine head. The bottom section of the bent pipe has an axis pointing to the bottom between the sleeve and the inner liner. The second rotating shaft rotates inside the bent pipe. The universal joint is provided at the bend of the bent pipe. A turntable is connected to the end of the universal joint away from the second rotating shaft through a connector. The dough hook is provided on the turntable.

[0012] A further technical solution of the present invention is that the dough hook is spiral-shaped, with the largest spiral diameter in the middle and gradually decreasing towards both ends.

[0013] A further technical solution of the present invention is that the pusher is positioned at the upper part of the inner liner.

[0014] A further technical solution of the present invention is that the sleeve is made of stainless steel and is sealed to the base, and a bearing is provided between the base and the sleeve.

[0015] A further technical solution of the present invention is that a first rotating shaft is provided on the base, a first driving component for driving the first rotating shaft to rotate is provided inside the base, and the inner liner is detachably installed on the first rotating shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting a sleeve inside the barrel, and the sleeve having a cavity inside, cooling material can be added into the cavity. The dough is pressed thin by the cooperation of the sleeve and the barrel. The sleeve acts as a heat conduction medium, transferring the heat in the dough to the cooling material inside, thereby cooling the dough and reducing its thickness, which can improve the cooling effect of the dough.

[0018] 2. By tilting the sleeve, the thickness of the dough at the top is greater than that at the bottom, and the weight of the dough at the top is also greater. When the dough uses its own weight to detach from the sleeve, it falls to the bottom of the sleeve, which simulates the effect of manually slapping dough, thus improving the kneading effect.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 The present invention provides the following technical solution: a water-based flour mixing device for dough processing, comprising a base 1, a head 2, a dough mixing hook 3, a dough separating unit 4, and a material cylinder 5;

[0032] The machine head 2 is located above the machine base 1 and protrudes to one side. The material cylinder 5 is installed on the machine base 1 and located below the protruding part of the machine head 2. The dough hook 3 and the dough separating unit 4 are installed on the machine head 2 and located inside the material cylinder 5. When working, flour and drinking water are added into the material cylinder 5, and the material cylinder 5 and the dough hook 3 start to rotate, so that the dough can be kneaded. The dough separating unit 4 is used to separate the dough inside the material cylinder 5.

[0033] Please see Figures 1-3The bottom of the base 1 protrudes towards the head 2. The material cylinder 5 is installed in the protruding direction of the base 1. A first rotating shaft 51 is provided on the base 1, and a first driving component for driving the first rotating shaft 51 to rotate is provided inside the base 1. The first driving component can be directly driven by a motor, or the motor can drive the first rotating shaft 51 to rotate through a transmission component. The bottom of the material cylinder 5 is fixed on the first rotating shaft 51 and is coaxially arranged with the rotation axis of the first rotating shaft 51, so that the first driving component can drive the material cylinder 5 to rotate through the first rotating shaft 51. It should be noted that in order to avoid the rotation speed of the material cylinder 5 being too fast, a geared motor can be used.

[0034] Please see Figure 3 Inside the machine head 2, there is a second drive assembly, which can also be driven by a motor or a transmission component. A second rotating shaft 31 is provided at the output end of the second drive assembly. The second rotating shaft 31 is vertically downward and extends from the inside of the machine head 2 to the outside of the machine head 2. One end of the second rotating shaft 31 located outside the machine head 2 is connected to the dough hook 3. Through the second drive component, the second rotating shaft 31 can be driven to rotate, so that the second rotating shaft 31 drives the dough hook 3 to rotate. When kneading dough, the dough can be kneaded by the rotation of the material cylinder 5 and the dough hook 3.

[0035] Please see Figures 2-5 The faceting unit 4 includes a column 41. A fixing member is provided at the protruding end of the machine head 2. The fixing member can be fixed to the machine head 2 with screws. The column 41 is fixed to the fixing member, so that the column 41 is relatively fixed to the machine head 2, and it is also convenient to disassemble the column 41. A base 42 is provided at the bottom of the column 41. A sleeve 44 is rotatably connected to the base 42 through a bearing 43. The sleeve 44 is made of stainless steel and is sealed to the base 42. The sleeve 44 is located between the base 42 and the column 41. Positioned as 1, the sleeve 44 is close to the inner wall of the barrel 5, and there is a gap between the sleeve 44 and the inner wall of the barrel 5. The base 42 is located below the sleeve 44, and a top cover 45 is provided on the top of the sleeve 44, so that the inside of the sleeve 44 forms a sealed cavity. In addition, a bearing 43 is also provided between the top cover 45 and the sleeve 44 to reduce the friction between the sleeve 44 and the top cover 45 and the base 42, so that the sleeve 44 can rotate relative to the base 42. The bearing 43 is an angular contact ball bearing.

[0036] The base 42 includes a chassis 421 and a partition 422. The partition 422 is located inside the sleeve 44 and is fixed to the chassis 421, so that the partition 422 can divide the cavity inside the sleeve 44 into two mirror-symmetrical small cavities. One side of the partition 422 is inclined. The end of the partition 422 near the chassis 421 is narrower, while the end away from the chassis 421 is wider, so that the partition 422 gradually moves away from the inner wall of the sleeve 44 from top to bottom through the inclined surface, so that the two small cavities inside the sleeve 44 are connected to each other. The top cover 45 is fixed to the partition 422 by screws or buckles.

[0037] Before kneading, ice cubes or ice water are added to the cavity. Then, the cavity is sealed by fixing the top cover 45 above the sleeve 44. After that, the material cylinder 5 and the kneading hook 3 rotate to knead the dough. When the material cylinder 5 rotates, it will bring the dough into the space between the sleeve 44 and the inner wall of the material cylinder 5, so that the sleeve 44 comes into contact with the dough. The sleeve 44 rotates due to the friction between it and the dough, so that the ice cubes can absorb the heat generated by the dough through the sleeve 44 to control the temperature of the dough during kneading. Under the action of the sleeve 44 and the material cylinder 5, the dough can be flattened to reduce the thickness of the dough and make the cooling effect of the dough better. In addition, the sleeve 44 is made of stainless steel, which has better thermal conductivity and can better control the temperature of the dough. The partition plate 422 is set with a slope, so that the sleeve 44 is located on the slope, which can accumulate more ice cubes. This position is located on the side of the sleeve 44 close to the material cylinder 5, thereby further improving the heat absorption effect of the ice cubes.

[0038] Please see Figures 4-6 A mounting groove 423 is provided in the middle of the partition plate 422. The column 41 is installed inside the mounting groove 423, and the bottom of the column 41 is rotatably located at the bottom of the mounting groove 423. The column 41 has space to rotate within the mounting groove 423. A notch is also provided on the top cover 45, which corresponds to the top of the mounting groove 423, allowing the column 41 to pass through the inside and outside of the mounting groove 423 and to swing within the notch. A connecting rod 46 is hinged to the top cover 45 at a diagonal position opposite the column 41. The end of the connecting rod 46 away from the top cover 45 is hinged to a sliding rod. The slide plate 47 slides along the extension direction of the machine head 2 at the bottom of the machine head 2. A limiting groove is provided on the machine head 2 to limit the sliding of the slide plate 47, thereby limiting the sliding freedom of the slide plate 47 and preventing the slide plate 47 from falling off the machine head 2. A drive unit 48 for driving the slide plate 47 to slide is also provided at the bottom of the machine head 2. The drive unit 48 is a hydraulic cylinder, or it can be a reciprocating structure that drives the slide plate 47 to slide back and forth through the second rotating shaft 31. In this embodiment, a hydraulic cylinder is preferred, so that the hydraulic cylinder can freely adjust the extension distance and extension frequency of the slide plate 47.

[0039] In use, the drive unit 48 can drive the slide plate 47 to slide at the bottom of the machine head 2, and the slide plate 47 can pull or push the top cover 45 to move via the connecting rod 46. However, since the sleeve 44 is located diagonally opposite the connecting rod 46 and is rotatably connected to the column 41, when the connecting rod 46 pulls the top cover 45, the top of the sleeve 44 will tilt away from the inner wall of the material cylinder 5, increasing the distance between the top of the material cylinder 5 and the sleeve 44, while the distance between the bottom of the material cylinder 5 and the side wall of the sleeve 44 remains almost unchanged. At this time, when the dough enters between the material cylinder 5 and the sleeve 44, most of the dough will pass through the top of the material cylinder 5, making the dough... The top of the drum is thicker than the bottom, and the weight of the dough at the top is also greater. Through gravity, when the dough detaches from the drum 5, it falls to the bottom, simulating the effect of manually pounding dough to improve kneading efficiency. When the connecting rod 46 pushes the top cover 45 to move, the distance between the top of the drum 5 and the sleeve 44 decreases, ensuring the distance between the upper and lower ends of the drum 5 and sleeve 44 remains consistent. When the dough enters, this reduces the dough's thickness, improving heat dissipation. The pushing and pulling action of the connecting rod 46 can be adjusted according to the dough's condition. In the early stages of kneading, before the dough has fully formed, the focus should be on cooling the dough. At this time, the drum... The distance between the upper and lower ends of sleeve 44 and 5 remains consistent. After the dough is formed, in order to improve kneading efficiency, connecting rod 46 should repeatedly push and pull sleeve 44 to achieve both the slapping effect and cooling of the dough. In addition, a fixing component is fixedly installed at the bottom of machine head 2, and the upper end of column 41 is fixedly connected to machine head 2 through this fixing component. The fixing component is fastened to machine head 2 with at least two bolts to ensure the rigidity of the connection. Column 41 is made of high-strength stainless steel or alloy steel, which has excellent bending and torsional resistance. Base 42 is rotatably connected to the bottom of column 41 through a rotating shaft to form a rigid support frame. The sleeve 44 is rotatably connected to the base 42 via a pair of angular contact ball bearings 43. These bearings 43 can simultaneously withstand radial and axial loads, ensuring that the force exerted by the dough on the sleeve 44 during the kneading process is stably transmitted to the base 42 and the column 41. The hinge mechanism between the connecting rod 46 and the top cover 45, as well as the arrangement of the drive unit 48 and the slide plate 47, together constitute a tilt adjustment system. The function of this system is limited to changing the working posture of the sleeve 44. Its structure does not bear the main mechanical load of the dough-separating unit 4. The main load is borne by the frame formed by the column 41 and the base 42, thereby ensuring the stability of the dough-separating unit 4 during the kneading process.

[0040] Please see Figure 2 , Figure 3 , Figure 8 and Figure 9The material cylinder 5 includes an outer cylinder 52 and an inner liner 53. The dough is located inside the inner liner 53. The outer cylinder 52 is fixed to the protruding part of the machine base 1 by screws. The inner liner 53 is rotatably disposed inside the outer cylinder 52. The opening of the inner liner 53 is provided with an outwardly extending flange that overlaps the opening of the outer cylinder 52. A first rotating shaft 51 passes through the outside of the outer cylinder 52 and is connected to the bottom of the inner liner 53, and is coaxial with the rotation axis of the inner liner 53. The inner liner 53 can be connected to the first rotating shaft 51 by snap-fit, so that the first rotating shaft 51 can drive the inner liner 53 to rotate when it rotates. Multiple openings are arranged in a ring array inside the inner liner 53, and the openings are close to the top of the inner liner 53. Multiple push blocks 54 are slidably disposed in the openings, and the push blocks 54 can push the dough into the inner liner 53. The internal protrusion can be flush with the inner wall of the inner liner 53. An elastic element 55 is provided on the flange of the inner liner 53. The elastic element 55 is used to push the push block 54 to move into the inner liner 53. The elastic element 55 is a spring sheet, so that the push block 54 protrudes into the inner liner 53 under the action of the elastic element 55. A limiting block is provided on the push block 54 to prevent the push block 54 from falling off the inner liner 53 and into the inner liner 53. A magnetic element 56 is provided on the side of the outer cylinder 52 located in the faceted unit 4. The magnetic element 56 can be a permanent magnet or an electromagnet. The push block 54 is made of a material that can be attracted by the magnetic element 56. Under the action of the magnetic element 56, the push block 54 can be moved away from the center of the inner liner 53 and one side of the push block 54 is flush with the inner wall of the inner liner 53.

[0041] During use, the inner liner 53 rotates the dough to the dough-separating unit 4. Since the rotation of the sleeve 44 is passive, it is insufficient to move the dough between the sleeve 44 and the inner liner 53. Therefore, under the pushing action of the pusher 54, when the inner liner 53 rotates, it can push the dough between the dough-separating unit 4 and the inner liner 53, avoiding the problem of the dough slipping on the inner liner 53 and having difficulty entering the dough-separating unit 4 and the inner liner 53. When the pusher 54 moves to the position between the dough-separating unit 4 and the inner liner 53, the magnetic component 56 pulls the pusher 54 into the space between the inner liner 53 and the outer cylinder 52, and makes the pusher 54 and the inner wall of the inner liner 53... When the dough is flattened by the dough-separating unit 4 and the inner liner 53 and moved out of the space between the dough-separating unit 4 and the inner liner 53, the pusher 54 disengages from the magnetic element 56. Under the action of the elastic element 55, the pusher 54 moves instantaneously towards the center of the inner liner 53, which can push the dough towards the center of the inner liner 53 and detach the dough from the inner liner 53. This avoids the dough sticking to the inner liner 53 and making it difficult to remove. In addition, the pusher 54 is positioned at the upper part of the inner liner 53, which can prevent drinking water from flowing out from the gap between the pusher 54 and the opening when the dough is still in a water-separated state, thus preventing the dough from becoming too dry.

[0042] Please participate Figure 7 and Figure 8The dough hook 3 is connected to the second rotating shaft 31 via a universal joint 32. A bent tube 33 is fixedly connected to the bottom of the machine head 2 by bolts. The bottom section of the bent tube 33 points to the bottom between the dough separating unit 4 and the inner liner 53. The second rotating shaft 31 rotates inside the bent tube 33. The universal joint 32 is located at the bend of the bent tube 33. A turntable 34 is connected to the end of the universal joint 32 away from the second rotating shaft 31 via a connector, so that the rotation axis of the turntable 34 also points to the bottom between the dough separating unit 4 and the inner liner 53. This makes the dough hook 3 inclined, with its bottom end close to the bottom between the dough separating unit 4 and the inner liner 53. Since there is no push block 54 at the bottom of the inner liner 53 to push the dough into the space between the dough separating unit 4 and the inner liner 53, when the dough hook 3 rotates, it can push the dough located at the bottom of the inner liner 53 to the space between the dough separating unit 4 and the inner liner 53 while performing the dough kneading function.

[0043] The dough hook 3 is mounted on the turntable 34. The dough hook 3 is spiral-shaped, with the largest spiral diameter in the middle and the smallest at both ends. The reduction in the spiral diameter at the top of the dough hook 3 reduces the diameter of the turntable 34, while the reduction in the spiral diameter at the bottom allows the dough hook 3 to penetrate deeper between the dough separating unit 4 and the inner pot 53. In addition, the tangents at the bottom and middle of the dough hook 3 form an angle α with the inner bottom wall of the inner pot 53. The reduction in the spiral diameter at the bottom of the dough hook 3 makes angle α smaller, allowing the side wall of the dough hook 3 to be closer to the inner bottom wall of the inner pot 53. This allows the dough at the bottom of the inner pot 53 to be mixed more thoroughly, and it is also easier to push the dough at the bottom of the inner pot 53 between the inner pot 53 and the dough separating unit 4, allowing the dough to be processed more thoroughly. Furthermore, the large spiral diameter in the middle of the dough hook 3 also increases the mixing range of the dough and improves the kneading effect.
