Fresh Bovine Hide Splitting Machine Reducing Chemical Residues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hide splitting machines for bovine hides often use limed or blued hides, which can reduce the quality of the top grain and collagen sheet, and are harmful to the machines and the environment.
Innovation Solution
A system and method for fresh bovine hide splitting that uses a hide splitting machine with specific components like apron plates, gauge rolls, ring rolls, and a knife assembly to split fresh bovine hides into top grain and collagen sheets with reduced chemical residues, improving the quality and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If limed or blued hides are used for splitting, then the hides can be preserved after removal from the animal, but the quality of the top grain and collagen sheet is reduced and chemicals are harmful to the environment and machines
Solution Approach 1:
The patent extracts and removes the harmful chemical treatment steps (liming and bluing) from the traditional hide processing workflow. By processing fresh hides without these chemical interventions, the system eliminates calcium and other chemical residues that harm the environment and degrade product quality, while still achieving successful hide splitting into top grain and collagen sheet.
Solution Approach 2:
The patent changes the fundamental parameter of hide state from chemically treated (limed/blued) to fresh/untreated. This parameter change fundamentally alters the processing requirements and outcomes, enabling high-quality collagen sheets with minimal chemical residues while maintaining effective hide preservation through controlled fresh processing conditions.
2Reliability
If limed or blued hides are used for splitting, then the hides can be preserved, but the chemicals alter the quality of the top grain and collagen sheet
Solution Approach 1:
The patent removes the chemical treatment steps that degrade quality, extracting only the essential preservation function through controlled fresh processing. This eliminates calcium residues and chemical alterations that would otherwise compromise the structural integrity and quality of the top grain and collagen sheet.
Solution Approach 2:
The patent performs preliminary preservation actions through controlled fresh processing before splitting, eliminating the need for subsequent chemical treatments. By establishing proper handling and processing conditions from the outset, the system preserves hide integrity without introducing degrading chemicals that would affect final product quality.
3Manufacturing precision
If fresh bovine hides are split without chemical treatment, then the quality of top grain and collagen sheet is improved, but the hides are more difficult to handle and process
Solution Approach 1:
The patent changes the processing parameters specifically for fresh hides, adjusting machine settings, processing speeds, and handling procedures to accommodate the unique properties of untreated hides. This enables high-quality output while maintaining operational ease through optimized fresh-hide-specific processing conditions.
4Reliability
If traditional limed or blued processing is used, then chemical residues remain in the collagen sheet, but the processing method is well-established and reliable
Solution Approach 1:
The patent extracts and eliminates the chemical treatment steps (liming and bluing) from the processing workflow, removing the source of calcium and chemical residues. This extraction approach maintains processing reliability through controlled fresh processing while achieving collagen sheets with minimal chemical contamination.

AI summary
A system and method for fresh bovine hide splitting includes a hide splitting machine configured to split a fresh bovine hide into a top grain and a collagen sheet. The top grain may be used for leather products. The collagen sheet may be processed with at least one of a maceration process or a drying process to produce a fresh bovine hide raw material product without the addition of a liming or bluing process. The fresh bovine hide raw material product may not include residues remaining following a liming process or bluing process. The fresh bovine hide raw material product may be usable in downstream products for human consumption including gelatin.
