Description

Technical Field

[0001] This invention relates to the field of dough stretching technology, and more particularly to a pretreatment device and method for hand-stretched dough. Background Technology

[0002] Pre-processing of hand-stretched noodles is a core step that determines the final texture and success rate of noodle stretching. Small catering businesses such as community noodle shops and family-run stores have an increasingly urgent need for integrated and miniaturized pre-processing equipment. Existing technology includes hand-stretched noodle pre-processing equipment based on a rotary multi-station architecture. This equipment integrates kneading, proofing, initial stretching, and cutting processes into one unit via a rotating worktable, effectively solving the problem of traditional assembly line equipment being too bulky and unsuitable for small kitchens. The initial stretching station of this type of equipment generally uses a bidirectional linear stretching mechanism, where two grippers pull the dough at opposite speeds to achieve initial stretching. Some equipment adds a simple planar pressing action at the kneading station to improve the uniformity of the dough.

[0003] However, in the aforementioned prior art, the initial stretching mechanism of the rotary pretreatment equipment can only apply axial tension in one direction, which cannot replicate the complex mechanical action of twisting, turning, finger pressing, and kneading into a cylinder during the initial stretching process by a skilled craftsman. As a result, the gluten network inside the dough is only arranged linearly in one direction along the stretching direction, and the stress distribution is extremely uneven. The final output dough pieces have a high breakage rate and low maximum elongation, and the stretching performance is fundamentally different from that of dough pieces pretreated by a skilled craftsman. Summary of the Invention

[0004] The purpose of this invention is to provide a pretreatment device and method for stretching handmade dough, thereby solving the problems in the prior art.

[0010] The pretreatment component further includes a shovel unit, which is disposed on one side of the base; The shoveling unit includes a shoveling lifting component, a shoveling telescopic component, a shoveling rotating component, a connecting member, and a tilting drive component. The shoveling lifting component is disposed on one side of the base. The output end of the shoveling lifting component is fixedly connected to the shoveling telescopic component. The output end of the shoveling telescopic component is fixedly connected to the connecting member. The flat shovel is rotatably connected to the connecting member. The shoveling rotating component is disposed on one side of the connecting member. The tilting drive component is disposed on one side of the flat shovel. The output end of the tilting drive component passes through the flat shovel and is fixedly connected to the tilting plate.

[0011] The torsion unit includes a torsion telescopic component, a support plate, a torsion drive component, and a torsion frame. The torsion telescopic component is disposed at one end of the base, and its output end is fixedly connected to the support plate.

The multi-directional moving unit is activated, driving the roller to move above the dough and flattening it by the back-and-forth rolling of the roller; After the dough is flattened, the flat spatula is inserted from below the dough, and then the flipping plate is activated to flip the dough on the flat spatula. After the dough is turned over and folded, the internal finger pressure block inside the roller extends out and applies a simulated joint finger pressure to the folded dough. After the pressing is completed, the rollers continue to roll and flatten the surface. After being rolled flat, the twisting unit performs a twisting operation on the dough; After pretreatment, the machine awaits cutting by staff before formal stretching.

[0015] This invention discloses a pre-treatment device and method for hand-stretching dough. The dough is placed on a rotating unit and adjusted to a preset angle by rotation. A multi-directional moving unit is activated, moving the rollers above the dough and flattening it through reciprocating rolling. After flattening, a flat spatula is inserted from below, and then a flipping plate is activated to flip the dough on the spatula. After the dough is flipped and folded, internal finger-pressure blocks inside the rollers extend to simulate joint finger pressure on the folded dough. After pressing, the rollers continue to roll and flatten. After flattening, a twisting unit twists the dough. The pre-treatment is complete, and the dough awaits cutting by workers before formal stretching. This integrated pre-processing procedure, encompassing flattening, automatic flipping and folding, joint finger pressure simulation, roller pressing and flattening, double-end twisting, and automatic kneading, perfectly replicates the complex mechanical action of a skilled craftsman's manual stretching pre-processing. It fundamentally solves the core defects of existing turntable equipment, which can only apply a single axial tension, resulting in a unidirectional linear arrangement of the gluten network within the dough and uneven stress distribution. The retractable internal finger pressure block with an expansion mechanism enables multi-point, adjustable, and precise pressing. Combined with the multi-layered structure after the dough is flipped and folded, it comprehensively organizes and strengthens the gluten network within the dough, forming a three-dimensional, interwoven, dense gluten structure. This increases the maximum elongation of the dough and reduces breakage. The yield rate is reduced; the double-end reverse twisting unit can make the gluten network form a spiral interwoven structure, further enhancing the stretching toughness and elasticity of the dough; the integrated automatic kneading unit can knead the pre-treated dough into a cylinder of uniform diameter in one go, eliminating the need for manual secondary shaping and significantly improving the consistency of subsequent cutting and formal stretching; the fully automated operation shortens the pre-treatment time of a single piece of dough, greatly improving production efficiency. At the same time, the overall structure of the equipment is compact and occupies a small area, perfectly adapting to the kitchen space and production needs of small catering businesses such as community noodle shops and mom-and-pop stores. Moreover, the taste of the pre-treated dough pieces is not significantly different from that of hand-pre-treated products, achieving a unity of handmade noodle quality and industrial efficiency.
