Description

Technical Field

[0001] This utility model relates to the technical field of pastry processing equipment, and in particular to a dough mixer. Background Technology

[0002] Food processing refers to the processing of grains, feeds, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and other foods such as vegetables, fruits, and nuts, all directly using agricultural, forestry, animal husbandry, and fishery products as raw materials. These processing activities constitute a type of agricultural product processing industry in a broad sense, and are also an important component of the food processing industry.

[0003] In northern my country, the majority of the population relies on wheat-based foods, making dough mixers the most suitable option for this population. Most existing dough mixers are small household mixers or mixers with a horizontal mixing shaft. These two types of dough mixers require a significant amount of time to knead the dough and remove air and gaps between the flour and water, generally resulting in excessive energy consumption. Utility Model Content

[0004] To address the issue of dough mixers requiring significant time to remove gas and gaps between flour and water, this application provides a dough mixer.

[0005] The dough mixer provided in this application adopts the following technical solution:

[0006] A dough mixer includes a support base, a dough mixing drum detachably connected to the support base, a liftable lifting plate above the dough mixing drum, a lifting electric cylinder connecting the support base and the lifting plate, a first rotating shaft rotatably connected to the lifting plate, the first rotating shaft being L-shaped, the vertical axis of the first rotating shaft being collinear with the axis of the dough mixing drum, a first rotating assembly driving the first rotating shaft to rotate along its vertical axis being provided on the lifting plate, a second rotating shaft rotatably connected to the end of the horizontal axis of the first rotating shaft, the second rotating shaft being L-shaped, a second rotating assembly driving the second rotating shaft to rotate along its vertical axis being provided between the second rotating shaft and the lifting plate, and a mixing element being provided at the end of the horizontal axis of the second rotating shaft.

[0007] Preferably, a fixing ring is connected to the support base, and a permanent magnet for adsorbing the dough-mixing cylinder is embedded in the fixing ring. The permanent magnet is arranged in a circular ring shape and is concentric with the fixing ring. A fixing block is fixedly connected to the bottom of the dough-mixing cylinder and is located at the center of the dough-mixing cylinder. A plug-in block is connected to the support base. The plug-in block is arranged in a cubic shape and has a plug-in groove for the plug-in block to be inserted into. The axis of the plug-in block is collinear with the axis of the fixing ring.

[0008] Preferably, the first rotating assembly includes a first fixed bearing, a connecting frame, and a rotating motor. The first fixed bearing is connected to the lifting plate, the vertical shaft of the first rotating shaft is connected inside the first fixed bearing, the connecting frame is connected to the lifting plate, the rotating motor is connected to the connecting frame, and the output shaft of the rotating motor is coaxially connected to the vertical shaft of the first rotating shaft through a coupling.

[0009] Preferably, the second rotating assembly includes a second fixed bearing, a fixed gear, and a rotating gear. The second fixed bearing is connected to the end of the horizontal axis of the first rotating shaft, and the vertical axis of the second rotating shaft is connected inside the second fixed bearing. The rotating gear is connected to the end of the vertical axis of the second rotating shaft that passes through the second fixed bearing. The fixed gear is connected below the lifting plate and is arranged in a ring shape. The vertical axis of the first rotating shaft can pass through the fixed gear, and the rotating gear and the fixed gear mesh with each other.

[0010] Preferably, the stirring component includes a fixed rod and an arc-shaped rod. One end of the fixed rod is connected to the end of the second rotating shaft. The arc-shaped rod is fixedly connected to the side wall of the fixed rod.

[0011] Preferably, the surfaces of both the fixed rod and the arc-shaped rod are coated with a nano-ceramic coating to prevent sticking.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The core innovation of this invention lies in its unique double "L"-shaped rotating shaft planetary mixing structure (a combination of a first rotating shaft and a second rotating shaft). The revolution of the first rotating shaft drives the mixing component to rotate around the central axis of the mixing drum, forming a wide-range mixing. While the first rotating shaft is revolving, the second rotating component forces the second rotating shaft to rotate. This combined motion of revolution and rotation causes the mixing component at the end to form an extremely complex and constantly changing motion trajectory within the mixing drum. This trajectory highly simulates the combined actions of folding, stretching, and rolling when kneading dough by hand, which can more effectively and quickly mix flour particles with water, forcefully squeezing and tearing air bubbles and insufficiently moistened flour clumps inside the dough. This accelerates the process of gas removal and gap elimination between flour and water. Compared with traditional single-rotation mixers (small household mixers) or horizontal shaft mixers, this planetary compound mixing can effectively improve the kneading effect, thereby achieving the effect of solving the problem that dough mixers need to spend a lot of time removing gas and gaps between flour and water.

[0019] This application discloses a dough mixer. (Refer to...) Figure 1 and Figure 2The dough mixer includes a support base 1, a dough mixing drum 2 detachably connected to the support base 1, a liftable lifting plate 3 above the dough mixing drum 2, a lifting electric cylinder 11 connecting the support base 1 and the lifting plate 3, a first rotating shaft 31 rotatably connected to the lifting plate 3, the first rotating shaft 31 being L-shaped, the vertical axis of the first rotating shaft 31 being collinear with the axis of the dough mixing drum 2, a first rotating assembly 4 on the lifting plate 3 driving the first rotating shaft 31 to rotate along its vertical axis, a second rotating shaft 32 rotatably connected to the end of the horizontal axis of the first rotating shaft 31, the second rotating shaft 32 being L-shaped, a second rotating assembly 5 between the second rotating shaft 32 and the lifting plate 3 driving the second rotating shaft 32 to rotate along its vertical axis, and a mixing component 6 at the end of the horizontal axis of the second rotating shaft 32.

[0020] The revolution of the first rotating shaft 31 drives the mixing component 6 to rotate around the central axis of the dough mixing drum 2, forming a large-scale mixing. When the first rotating shaft 31 revolves, the second rotating component 5 forces the second rotating shaft 32 to rotate. This combined motion of revolution and rotation causes the mixing component 6 at the end to form an extremely complex and constantly changing motion trajectory within the dough mixing drum 2. This trajectory highly simulates the combined actions of folding, stretching, and rolling when kneading dough by hand, which can more effectively and quickly mix flour particles with water, forcefully squeeze and tear air bubbles and insufficiently moistened flour clumps inside the dough, thereby accelerating the process of gas expulsion and gap elimination between flour and water.

[0021] A fixing ring 12 is connected to the support base 1. A permanent magnet 121 for adsorbing the dough mixing cylinder 2 is embedded in the fixing ring 12. The permanent magnet 121 is arranged in a circular shape and is concentric with the fixing ring 12. A fixing block 21 is fixedly connected to the bottom of the dough mixing cylinder 2. The fixing block 21 is located at the center of the dough mixing cylinder 2. A plug-in block 13 is connected to the support base 1. The plug-in block 13 is arranged in a cubic shape. The fixing block 21 has a plug-in groove for the plug-in block 13 to be plugged in. The axis of the plug-in block 13 is collinear with the axis of the fixing ring 12.

[0022] The combination design of the permanent magnet 121 fixing ring 12 and the plug block 13 / plug slot on the support base 1 provides double fixation protection.

[0023] The first rotating assembly 4 includes a first fixed bearing 41, a connecting frame 42, and a rotating motor 43. The first fixed bearing 41 is connected to the lifting plate 3, the vertical shaft of the first rotating shaft 31 is connected inside the first fixed bearing 41, the connecting frame 42 is connected to the lifting plate 3, the rotating motor 43 is connected to the connecting frame 42, and the output shaft of the rotating motor 43 is coaxially connected to the vertical shaft of the first rotating shaft 31 through a coupling.

[0024] The second rotating assembly 5 includes a second fixed bearing 51, a fixed gear 52, and a rotating gear 53. The second fixed bearing 51 is connected to the end of the horizontal axis of the first rotating shaft 31. The vertical axis of the second rotating shaft 32 is connected inside the second fixed bearing 51. The rotating gear 53 is connected to the end of the second fixed bearing 51 through which the vertical axis of the second rotating shaft 32 passes. The fixed gear 52 is connected to the lower part of the lifting plate 3. The fixed gear 52 is arranged in a ring shape. The vertical axis of the first rotating shaft 31 can pass through the fixed gear 52. The rotating gear 53 and the fixed gear 52 mesh with each other.

[0025] The stirring component 6 includes a fixed rod 61 and an arc-shaped rod 62. One end of the fixed rod 61 is connected to the end of the horizontal axis of the second rotating shaft 32. The arc-shaped rod 62 is fixedly connected to the side wall of the fixed rod 61. The arc-shaped rod 62 is arranged along the length direction of the fixed rod 61, and several arc-shaped rods 62 are arranged at equal intervals along the circumference of the fixed rod 61.

[0026] Both the fixed rod 61 and the arc rod 62 have a nano-ceramic coating to prevent sticking. This coating has the characteristics of being ultra-smooth and having low surface energy, giving it excellent anti-sticking performance.

[0027] The lifting plate 3 may be connected to a protective cover, which can cover the first rotating shaft 31, the second rotating shaft 32, the first rotating component 4 and the second rotating component 5 inside.

[0028] The implementation principle of a dough mixer according to an embodiment of this application is as follows: During operation, flour and water are first added to the mixing drum 2 according to the ratio. Then, the lifting plate 3 is lowered by the lifting cylinder 11, so that the mixing component 6 is placed in the mixing drum 2. Then, the first rotating shaft 31 is driven by the rotating motor 43 to revolve around the axis of the mixing drum 2. The first rotating shaft 31 drives the second rotating shaft 32 and the mixing component 6 to revolve synchronously. Due to the meshing of the fixed gear 52 and the rotating gear 53, the revolve motion drives the rotating gear 53 to rotate around the fixed gear 52. The rotating gear 53 drives the second rotating shaft 32 to rotate around its vertical axis, so that the mixing component 6 also rotates synchronously. The mixing component 6 can perform high-intensity mixing of flour and water in the combined motion of revolve and rotation.

[0029] After mixing is complete, turn off the rotating motor 43. After the mixing component 6 has completely stopped, use the lifting cylinder 11 to raise the lifting plate 3 to the highest position so that the mixing component 6 is separated from the dough mixing drum 2. Then, overcome the attraction of the permanent magnet 121 and lift the dough mixing drum 2 vertically upward to remove the dough.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
