Description

Technical Field

[0001] This utility model relates to the field of bread processing technology, specifically to a dough rolling device. Background Technology

[0002] The making of bread typically involves multiple processing steps. The ideal texture of bread depends on a uniformly distributed porous structure. During the rolling process, the gas within the dough is redistributed, and the previously chaotic air bubbles become orderly. Rolled dough expands more evenly during fermentation and baking, forming fine, uniform air pockets, giving the bread a soft texture and good chewiness, significantly improving its quality. However, current rolling equipment has a low degree of automation and cannot achieve the necessary centering and initial flattening of the dough before rolling. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1-5 As shown, this utility model provides a dough pressing device. The rolling press 6 is mainly used to process dough. Through the centering and straightening mechanism 601, the flattening mechanism 603 and the rolling mechanism arranged in sequence, the dough is adjusted to a suitable position and initially flattened, and finally pressed into a dough sheet, which is ready for subsequent food processing steps. The rolling press 6 includes a rolling conveyor 602, which provides a continuous conveying channel for the processing of dough, so that the dough can pass through the centering and straightening mechanism 601, the flattening mechanism 603 and the rolling mechanism in sequence to realize the automated processing flow of dough. The rolling conveyor 602 is arranged in sequence along its conveying direction with a centering and straightening mechanism 601 that can adjust and center the position of the dough, a flattening mechanism 603 for initially flattening the dough and a rolling mechanism for pressing the dough into a dough sheet.

[0027] The centering and straightening mechanism 601 includes a straightening bracket 601a, on which two straightening belt structures are arranged in a figure-eight shape. Each straightening belt structure includes two pulleys 601b, and a straightening belt 601c is connected between the two pulleys 601b. One of the pulleys 601b of each straightening belt structure is driven to rotate by a straightening motor 601d fixedly mounted on the straightening bracket 601a. ​​When the dough is conveyed to the centering and straightening mechanism 601 on the roller conveyor 602, the rotation of the straightening belt 601c will apply a lateral force to the dough, causing the dough to gradually move towards the center of the conveying channel, thereby achieving the adjustment and centering of the dough position.

[0028] The flattening mechanism 603 includes a flattening cover 603b, a flattening roller 603c rotatably mounted on the lower side of the flattening cover 603b, and a flattening motor 603a mounted on the flattening cover 603b for driving the flattening roller 603c to rotate. When the dough passes through the flattening mechanism 603, the rotation of the flattening roller 603c applies pressure to the dough, initially flattening it and making the dough thickness relatively uniform, thus creating better conditions for the subsequent rolling process.

[0029] The rolling mechanism includes a rolling press housing 604, on which three or more sets of rolling cylinders are mounted. Each set of rolling cylinders consists of a first rolling cylinder 607 and a second rolling cylinder 608. A rolling transmission structure 609 is provided between the first rolling cylinder 607 and the second rolling cylinder 608 to enable them to rotate synchronously in opposite directions. A rolling motor 605 is mounted on the rolling press housing 604 to drive the first rolling cylinder 607 to rotate via the rolling transmission structure 609. When the dough, after initial flattening, enters the rolling mechanism, the synchronous opposite rotation of the first rolling cylinder 607 and the second rolling cylinder 608 further compresses and stretches the dough, gradually pressing it into a dough sheet that meets the requirements. A first flour spreader 610 is mounted on the rolling conveyor 602 located between the flattening mechanism 603 and the rolling press housing 604. A dough sheet conveyor 612 is located below the lowest set of rolling cylinders for conveying the dough sheet.

[0030] Working principle:

[0031] The roller conveyor 602 of the roller press 6 transports the dough. The centering and leveling mechanism 601 includes a leveling bracket 601a, a pulley 601b, a leveling belt 601c, and a leveling motor 601d. The leveling motor 601d drives the leveling belt 601c to rotate, adjusting the dough position to be centered. The flattening mechanism 603 includes a flattening cover 603b, a flattening roller 603c, and a flattening motor 603a. The flattening motor 603a drives the flattening roller 603c to rotate, initially flattening the dough. The rolling mechanism includes a rolling press housing 604, a first rolling cylinder 607, a second rolling cylinder 608, a rolling transmission structure 609, and a rolling motor 605. The rolling motor 605 drives the first and second rolling cylinders 607 and 608 to rotate synchronously in opposite directions through the rolling transmission structure 609, gradually pressing the dough into a flatbread. A fourth conveyor 14 is provided between the rolling press 6 and the rolling machine 7. A fifth conveyor 15 is provided below the rolling conveyor 701 for conveying the tray. A first flour sprinkler 16 is provided on the rolling conveyor 602, and a second flour sprinkler 17 is provided on the fourth conveyor 14, for sprinkling flour on both sides of the pressed flatbread.
