Kneading Bowl Scraper Ring for Cleaner Dough Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear scrapers in kneading machines for doughs are inefficient in preventing dough contamination of the closure device, leading to frequent cleaning needs and operational issues.
Innovation Solution
A scraper ring that surrounds the opening of the kneading bowl, rotating with it to effectively wipe off dough residues from the closure body during discharge, ensuring continuous operation and reducing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear scraper is used to wipe off dough from the closure body, then dough contamination is reduced, but the scraper requires frequent cleaning and maintenance
Solution Approach 1:
The invention replaces the conventional linear scraper with a scraper ring that has a curved, annular shape matching the circular opening of the kneading bowl. This curved geometry allows the scraper ring to maintain continuous contact with the closure body throughout its rotation, providing more effective and uniform dough removal across the entire closure surface, thereby reducing contamination and cleaning frequency
2Reliability
If a linear scraper is used to prevent dough adhesion, then contamination is reduced, but operational efficiency decreases due to frequent maintenance
Solution Approach 1:
The scraper ring rotates continuously with the kneading bowl, maintaining constant contact with the closure body throughout the entire rotation cycle. This continuous scraping action ensures that dough is removed from all areas of the closure body without interruption, providing uninterrupted contamination prevention and eliminating the need for frequent maintenance stoppages, thereby improving operational efficiency
3Duration of action of stationary object
If a scraper ring is used to wipe off dough, then cleaning function is maintained longer, but device complexity increases
Solution Approach 1:
The scraper ring serves multiple functions simultaneously: it scrapes dough from the closure body, cleans the opening area, and its rotating motion distributes dough residues across its entire circumference for gradual removal. This multi-functionality allows a single component to perform what would otherwise require multiple separate scraping elements, maintaining extended cleaning effectiveness without proportionally increasing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The scraper ring maintains its cleaning function for a longer period, preventing dough from adhering to the closure device and reducing maintenance frequency, thereby enhancing operational efficiency.
Implementation Method 1
an underside of the scraper ring contacts an upper side of the closure body to wipe off a portion of the food dough located on the closure body

AI summary
A kneading machine for food dough includes a rotatable kneading bowl, which includes in a bottom a central opening to discharge the food dough, and a closure at or in a vicinity of the opening in an operating position by a movable closure body, and to release the opening to discharge the food dough in a discharge position. The opening is at least partially surrounded by a scraper ring fastened to the kneading bowl and operable to cause an underside thereof to contact with the upper side of the closure body to wipe off a food dough located on the closure body when the closure body is moved from the operating position into the discharge position.
