Bonemill with Replaceable Milling Inserts for Slaughter Residue Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of slaughter residues is challenging due to high costs and loss of nutritional and energy value, with existing methods requiring special logistics and sanitary regulations, and existing solutions fail to effectively convert these residues into usable raw materials.
Innovation Solution
A bonemill device that processes slaughter residues into a usable raw material by using replaceable milling inserts and a design that prevents aggressive material disposal, allowing for easy maintenance and sanitation, and producing a finely milled product suitable for pet food or animal feed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If slaughter residues are destroyed by combustion or composting, then the waste is eliminated, but the nutritional and energy value is lost
Solution Approach 1:
The invention changes the physical state and particle size parameters of the slaughter residues through mechanical milling, transforming them from unsuitable waste material into fine pulp with appropriate characteristics for animal feed applications, thereby preserving nutritional value while eliminating harmful waste disposal requirements
Solution Approach 2:
The invention converts what was previously considered harmful waste material requiring expensive disposal into a beneficial raw material for animal feed production, transforming the problem of waste elimination into an opportunity for resource utilization
2Reliability
If special logistics chain is used for waste handling, then sanitary regulations are complied with, but handling costs increase
Solution Approach 1:
The milling device incorporates self-cleaning capabilities through its design, where the rotating milling bodies and channel geometry automatically clean themselves during operation, eliminating the need for separate cleaning systems and complex sanitation logistics while maintaining sanitary compliance
3Productivity
If aggressive material disposal is used, then processing efficiency is improved, but engine demands increase
Solution Approach 1:
The invention uses dynamically adjustable milling bodies that can adapt their position and configuration during operation, optimizing the milling action to achieve efficient processing with reduced power consumption by avoiding excessive force application
4Manufacturing precision
If complex milling bodies are used, then milling effectiveness is improved, but maintenance difficulty increases
Solution Approach 1:
The milling bodies are segmented into modular components with standardized parts that can be easily replaced or maintained, allowing complex milling functionality to be achieved while keeping maintenance simple through component interchangeability

AI summary
The present invention pertains to a bonemill (1) intended particularly to grind slaughter residue in the form of bones and bone-like residue products. Such a device features among others a processing channel (2), equipped with a transport element (3) for transportation of a millable material (4) toward a milling unit (6). The milling unit comprises two parallel spindles (9) which in turn feature milling bodies (7) arranged in pairs with substantially evenly distributed replaceable milling inserts (8). The milling inserts protrude from the cylindrical surface of the milling body while being separate from each other by tracks (14) and intermediate ridges (15) formed in the surface of the milling body. The processing channel (2) is arranged to form a screw housing surrounding the millable material (4), and featuring a milling inlet (16) oriented toward the milling unit. The inlet has an extension in the rotational plane of the milling bodies which is shorter than the total extension of the milling bodies in their rotational plane. The milling inlet also has an extension in the spindle's (9) longitudinal direction which is shorter than the milling unit's processing width.
