Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, in particular to an automatic dough mixer for bread processing. Background Art

[0002] Flour mixer is a necessary device for all kinds of noodle machines and cold noodle machines. It can also be used for various other pasta and other powdery objects or loose colloids. Its function is to mix flour and the configured water into flocculent dough and then make bread. The following are the main steps of making bread. Mix flour, yeast, salt, sugar and water together and stir into dough. You can use manual mixing or dough mixer to mix the dough. Kneading: Put the dough on the countertop and knead the dough by hand until the dough becomes smooth, soft and elastic. This process helps the gluten in the dough develop and makes the bread chewier. Fermentation: Put the kneaded dough in a warm and humid environment and let the dough ferment. The fermentation time is usually 1 to 2 hours, until the dough volume increases and bubbles appear on the surface. Shaping: Take out the fermented dough and shape it according to your favorite shape. The dough can be placed in a baking tray or molded into a specific shape with a mold. Baking: Put the fermented dough in a preheated oven and bake it at an appropriate temperature and time. The baking time depends on the size and shape of the bread, usually 20 to 40 minutes. Cooling: Remove the bread from the oven and place on a rack to cool.

[0024] Example:

[0025] Reference Figure 1-Figure 4 An automatic dough mixer for bread processing includes a base, a mounting seat is fixedly connected to the base, a placing plate 3 is rotatably connected to the mounting seat, and the mounting seat is arranged on one side of the axial position of the placing plate 3, so that the placing plate 3 can be rotated on the mounting seat, a placing plate is rotatably connected inside the placing plate 3, the placing plate can be driven by a motor, and a mixing drum 2 is fixedly connected to the placing plate, so that the placing plate can drive the mixing drum 2 to rotate.

[0026] A working box 1 is fixedly installed on the base through a connecting plate, a slide groove 101 is opened on the inner bottom of the working box 1, and the movable block 5 is slidably connected to the slide groove 101, and a stirring shaft 102 is rotatably connected to the movable block 5, and the working end of the stirring shaft 102 extends to the cavity of the mixing drum 2, and a driving machine or motor is provided on the movable block 5 to drive the stirring shaft 102 to rotate, and the stirring shaft 102 is a spiral style, and the position of the movable block 5 is away from the central axis of the mixing drum 2, and does not overlap or contact with it, so that the movable block 5 is displaced on one side of the central axis of the mixing drum 2.

[0027] In addition, a cam 4 is rotatably connected in the working box 1, and the cam 4 is driven by a high-torque motor or a driving machine, such as a stepping motor DM860H or 450B, so that it can drive the cam 4 to rotate in the working box 1. A limit block is also provided in the working box 1, and a connecting rod 501 is slidably connected to the limit block, and one end of the connecting rod 501 is fixedly connected to the movable block 5, and the other end of the connecting rod 501 is against the outer wall of the cam 4. A rotating seat can be provided on the connecting rod 501, and a rotating contact wheel is installed on the rotating seat, and then the contact wheel is against the outer wall of the cam 4. The other end of the connecting rod 501 can also be directly against the outer wall of the cam 4, so that when the cam 4 rotates, it drives the connecting rod 501 to move.

[0028] In order to better reset the connecting rod 501, a spring 502 is fixedly connected to the limit block, and the other end of the spring 502 is fixedly connected to the movable block 5. Two groups of springs 502 are provided to improve the resetting effect of the connecting rod 501, and the movable block 5 slides in the slide groove 101, so that the spiral stirring shaft 102 reciprocates in the stirring drum 2, so that the stirring shaft 102 is displaced in the axial direction of the stirring drum 2, and the stirring drum 2 can cooperate with the stirring shaft 102 to rotate, so that the various raw materials at the bottom of the stirring drum 2 and the flour are more fully mixed together, so as to avoid the situation where there is dry powder or uneven mixing in the dough.

[0029] At the same time, in order to better improve the stirring effect in the mixing drum 2, a guide cylinder 7 is fixedly connected to the base, and a guide rod 701 is slidably connected to the guide cylinder 7, a piston is arranged on the guide rod 701, and the piston fits against the inner wall of the guide cylinder 7, and the top of the guide rod 701 can be against the bottom of the placement plate 3, a booster cylinder 6 is also fixedly connected in the working box 1, and a booster rod 601 is slidably connected to the booster cylinder 6, a piston is also arranged on the booster rod 601, and the piston fits against the inner wall of the booster cylinder 6, and the end of the booster rod 601 away from the piston is fixedly connected to the connecting rod 501 through a connecting plate, and then the booster cylinder 6 and the guide cylinder 7 are connected through a pipeline.

[0030] Here, when the connecting rod 501 is displaced by the rotation of the cam 4, the connecting rod 501 will drive the boosting rod 601 to move, and then the gas in the boosting cylinder 6 is transported to the guide cylinder 7. At this time, the guide rod 701 moves outward to push the bottom of the placement plate 3, so that the placement plate 3 can be rotated on the mounting seat. At this time, the mixing drum 2 is tilted, and the horizontal position of the mixing drum 2 is changed, thereby displacing the mixture in the mixing drum 2. When the connecting rod 501 is reset, the mixing drum 2 on the placement plate 3 will press down the guide rod 701 under its own gravity, and air will be transported to the boosting cylinder 6. In this process, the spring 502 can also be used to reset the connecting rod 501. When the dough in the mixing drum 2 needs to be taken out, the placement plate 3 can be rotated, and then the mixing drum 2 can be tilted to facilitate the removal of the dough inside.

[0031] However, the inclination angle of the mixing drum 2 is between 10° and 15°. The angle will affect the operation of the mixing shaft 102. In this device, it can be preferably 12°. By changing the horizontal position of the mixing drum 2, the reciprocating mixing shaft 102 can be used to fully mix the internal flour and raw materials. At the same time, the inclined mixing drum 2 can also assist in turning the internal flour, which can further improve the mixing effect of the dough.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
