Mincing Machine Cutter Head Centrifugal Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mincing machines do not effectively produce high-quality minced products, particularly with fibrous or sinewy materials, as they often result in a battered or crushed texture rather than granular particles due to the interaction of hole plates with 90° cutting edges, and lack flexibility in product feeding and throughput.
Innovation Solution
A mincing machine design featuring a cutter head mounted upstream of stationary hole plates, with adjustable axial gap and driven by the same shaft as the rotating hole plates, which exerts centrifugal force for improved product feeding and interaction with hole plates, allowing for adjustable hole diameters and additional pre-mincing stages for enhanced quality and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hole plates with 90° cutting edges are used for mincing, then the product appears creamier, but the cutting quality deteriorates as no granular particles are produced and the product is more battered or crushed than cut
Solution Approach 1:
The invention introduces a cutter head with cutting blades positioned upstream of the hole plates to perform preliminary cutting of the product. This preliminary action creates granular particles before the product enters the hole plates, thereby improving cutting quality while the hole plates subsequently process the pre-cut material to achieve the desired creaminess
Solution Approach 2:
The mincing process is divided into two distinct stages: first, the cutter head performs coarse cutting to create granular particles, and second, the hole plates perform fine processing to achieve creaminess. This segmentation allows each component to optimize its function without compromising the other
2Manufacturing precision
If a cutter head is added upstream of the hole plates to perform preliminary mincing, then the quality of minced product improves, but the device complexity increases
Solution Approach 1:
The cutter head is integrated onto the same drive shaft as the hole plates, merging the drive mechanisms of both components. This combining approach improves minced product quality through preliminary cutting while minimizing the increase in device complexity by sharing the rotational drive system
3Adaptability or versatility
If the gap between the cutter head and the hole plate is made adjustable, then the flexibility in throughput and product quality improves, but the device complexity increases
Solution Approach 1:
The gap between the cutter head and the first hole plate is made adjustable through a mechanical adjustment mechanism, allowing the system to dynamically adapt to different product types and throughput requirements. This dynamic adjustment capability improves versatility while the mechanism is designed to be as simple as possible
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 machine produces a higher-quality minced product with improved consistency and color, particularly with fibrous materials, by combining preliminary mincing with the cutter head and hole plates, and allows for adjustable throughput and heat transfer, resulting in a creamier texture and finer particle size.
Implementation Method 1
the arrangement of the cutter head before the hole plates has the advantage that the product feed to the hole plates is improved since the cutter head exerts a centrifugal force on the product being minced and, if the cutter blades are arranged in a suitable oblique direction, the product is pressed against the first stationary hole plate

AI summary
A mincing machine for mincing a product, in particular for mincing meat, includes at least one stationary hole plate and at least one rotating hole plate which interact to mince the product. The mincing machine has a rotating cutter head mounted on a shaft wherein said cutter head is arranged upstream of the interacting hole plates in the conveying direction of the product to be minced in order to interact with a stationary hole plate to mince the product.
