Meat Mincer Blade Guide Channels Prevent Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meat mincer blade discs fail to effectively distribute and process solid components, leading to clogging and inefficiencies in mixing and shredding due to the migration of hard parts towards the hub, resulting in incomplete processing and perforated disc damage.
Innovation Solution
Incorporation of guide channels within the cutting elements that facilitate a flow path for material, allowing hard components to be transported from the inner to the outer opening, enabling repeated processing and preventing clogging by ensuring all material is broken down to fit through the perforated disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solid components are allowed to migrate towards the hub, then the cutting elements can process material, but the solid components accumulate in the center resulting in clogging and creasing of the orifice plate
Solution Approach 1:
The cutting elements are segmented into multiple sections along their length, with each section having different functional characteristics. The first section has a first cutting edge for initial cutting, while the second section has a second cutting edge at a different angle for further processing. This segmentation allows different parts of the solid components to be handled differently, preventing accumulation and clogging while maintaining processing efficiency.
Solution Approach 2:
Different sections of the cutting elements have locally optimized properties: the first section is optimized for initial cutting with a specific cutting edge angle, while the second section is optimized for further processing with a different cutting edge angle. This local quality variation ensures that solid components are progressively processed and directed outward rather than accumulating at the hub.
2Ease of manufacture
If cutting edges are reduced in length on the exit side, then some cutting edges can be optimized, but good mixing can only take place up to the next fully developed cutting edge
Solution Approach 1:
The cutting elements provide continuous cutting action along their entire length through multiple cutting edges arranged in sequence. As material passes through the cutter, it encounters successive cutting edges that continuously process and mix the material, ensuring complete mixing throughout the entire cutting element length rather than stopping at the transition to fully developed cutting edges.
3Object-generated harmful factors
If discharge channels are added for hard parts, then hard components can be removed, but the outlet openings are limited and may not prevent clogging effectively
Solution Approach 1:
The cutting elements serve multiple functions: they cut material with their cutting edges, guide solid components through their structured sections, and facilitate outward movement of hard parts through their design. This multi-functionality eliminates the need for separate discharge channels while still achieving effective removal of hard components and prevention of clogging.
