Modular Injection Chamber for Meat Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for injecting treatment fluids into meat or fish products face high maintenance and cleaning costs due to complex assembly and leak-tightness requirements, making these processes labor-intensive and expensive.
Innovation Solution
A modular injection chamber structure with interconnected longitudinal and transverse ducts, equipped with oscillating plates and seals, allows for easy detachment, assembly, and cleaning, featuring a block that can be fixed using articulated bolts and nuts for improved handling and leak-tightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional injection chamber structure is used, then the system maintains structural integrity and leak-tightness, but the maintenance and cleaning tasks become very expensive and labor-intensive due to difficulty of disassembly
Solution Approach 1:
The injection chamber is divided into multiple detachable blocks (first block, second block, third block) that can be easily separated from each other. Each block contains specific components (needles, ducts, seals) that can be independently accessed, removed, and cleaned. This segmentation allows maintenance personnel to disassemble the chamber for cleaning without requiring complete disassembly of the entire injection system, significantly reducing maintenance time and labor costs while maintaining structural integrity during operation.
2Ease of repair
If the injection chamber is made as a single integrated unit, then leak-tightness is maintained, but the cleaning and inspection tasks require significant labor time and are expensive
Solution Approach 1:
The block structure is pre-configured with integrated sealing elements (seals, gaskets, or O-rings) at all connection interfaces between blocks and with the housing. These sealing components are built into the design from the beginning, ensuring leak-tightness is maintained during assembly. The seals are positioned at critical junctions where blocks connect to the housing and to each other, preventing fluid leakage while allowing the blocks to be easily detached for cleaning and reassembled for operation.

If the injection chamber structure is simplified for easy maintenance, then labor costs are reduced, but the structural integrity and leak-tightness may be compromised
