Dumpling Wrapper Texture Orientation for Filling Pocket Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated dumpling manufacturing results in dumplings with a loose stuffing alignment and less appealing visual appearance due to unidirectional sheeting of dough, leading to reduced filling pocket height and juiciness compared to handmade dumplings.
Innovation Solution
A method and device that cut dough sheets into dumpling wrappers and wrap them at an angle of 0 to 20 degrees relative to the texture orientation, aligning the fold line with the texture orientation to enhance stuffing retention and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unidirectional sheeting is used to mechanically process dough, then manufacturing efficiency is improved, but the texture orientation causes shrinkage in the sheeting direction resulting in reduced filling pocket height
Solution Approach 1:
The patent applies asymmetry by changing the orientation angle between the fold line and texture orientation from the conventional 90 degrees to 0-20 degrees. This asymmetric adjustment compensates for the unidirectional shrinkage effect, allowing the filling pocket height to be maintained or increased while preserving the efficiency benefits of mechanical sheeting.
Solution Approach 2:
The patent changes the critical parameter of fold line orientation angle from 90 degrees to 0-20 degrees relative to texture orientation. This parameter change transforms the adverse effect of unidirectional shrinkage into a beneficial outcome, achieving both high manufacturing efficiency and excellent dumpling shape with increased filling pocket height.
2Extent of automation
If unidirectional sheeting is used to mechanically process dough, then automation is improved, but the stuffing alignment becomes loose resulting in reduced juiciness
Solution Approach 1:
By setting the fold line at an asymmetric angle of 0-20 degrees relative to texture orientation rather than the conventional perpendicular orientation, the patent creates optimal alignment conditions for stuffing. This asymmetric configuration works with the unidirectional texture to tighten stuffing alignment and improve juiciness while maintaining full automation.
Solution Approach 2:
The patent modifies the orientation angle parameter to optimize stuffing retention. This parameter change ensures that the mechanical sheeting process produces texture orientation that works synergistically with the folding process to achieve tight stuffing alignment, combining automation with improved product quality.
3Ease of manufacture
If the fold line is perpendicular to texture orientation, then traditional manufacturing methods are followed, but the dumpling width increases while height reduces resulting in less appealing appearance
Solution Approach 1:
The patent replaces the symmetric perpendicular orientation (90 degrees) with an asymmetric orientation of 0-20 degrees between fold line and texture. This asymmetric approach produces dumplings with superior visual appeal including increased height and tighter stuffing, while remaining easy to implement in automated manufacturing.
Solution Approach 2:
By changing the fold line orientation parameter from 90 degrees to 0-20 degrees, the patent achieves improved dumpling shape characteristics. This simple parameter change in the manufacturing process delivers visually appealing dumplings with better height-to-width ratio and tighter stuffing alignment.

AI summary
The present invention provides a dumpling producing method and a dumpling producing device. The method comprises the following steps: cutting a mechanically sheeted dough sheet of a unidirectional texture into dumpling wrappers of a pre-defined shape, filling the stuffing into the dumpling sheet, and wrapping the dumpling wrapper along a fold line at an angle of 0 to 20 degrees to the texture orientation of each dumpling wrapper to produce the dumplings. The device comprises: a cutting mechanism consisting of a cutting unit and a rotating unit, wherein the rotating unit is configured to cause an angle formed between the texture orientation of the dumping wrapper and the fold line to be within 0 to 20 degrees.
