Continuous Meat Grinding Reclaiming System with Variable Valve Reducer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current meat grinding systems face challenges in distinguishing contaminated meat from different batches, require refrigerated storage for rework meat, involve time-consuming reprocessing, and incur increased labor and handling costs due to the need for separate processing and storage of pure and rework meat.
Innovation Solution
A continuous meat grinding reclaiming system comprising a primary and secondary grinder unit that processes meat in a single run, separating pure meat from bone and foreign objects, and using a variable valve reducer to control the flow of undesireables, allowing for simultaneous processing and reducing storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If meat batches from different lots are grouped together and collected into a single container during initial processing, then processing efficiency is improved, but contamination tracing becomes difficult and may require discarding the entire container lot
Solution Approach 1:
The system divides the processing into separate segments: primary grinding separates pure meat from bone-containing meat, which is then sent to secondary grinding. Each segment maintains batch identification, allowing contamination tracing while improving overall processing efficiency through specialized handling at each stage.
2Productivity
If rework meat is stored in a refrigerated room for later reprocessing, then processing capacity is improved, but temperature control must be maintained and bacterial growth risk increases
Solution Approach 1:
The system performs preliminary separation in the primary grinder, extracting pure meat immediately and sending only bone-containing rework meat to secondary processing. This preliminary action reduces the amount of meat requiring storage and reprocessing, minimizing temperature control requirements and bacterial growth risks.
3Manufacturing precision
If rework meat undergoes additional reprocessing at a later time, then separation completeness is improved, but time delay and labor costs increase
Solution Approach 1:
The system establishes continuous action by immediately transferring bone-containing meat from primary grinding to secondary grinding without storage delays. The secondary grinder continuously processes rework meat in real-time, maintaining separation completeness while eliminating time delays and reducing labor costs associated with batch reprocessing.
4Quantity of substance
If pure meat from rework grinder is mixed back into original batches of pure meat, then overall yield is improved, but contamination risk increases and batch identification is lost
Solution Approach 1:
The system extracts pure meat from the rework grinding process into a separate collection container, keeping it distinct from original pure meat batches. This extraction maintains batch identification and contamination tracing capability while still achieving high overall yield by recovering additional pure meat that would otherwise be discarded with the bone-containing waste.

AI summary
An continuous meat grinding reclaiming system that provides a primary meat grinder unit and a secondary meat grinding unit for continuously and simultaneously processing a meat batch in a single processing run. The primary meat grinder unit is designed to grind a batch of meat by initially separating or extrapolating pure meat from the meat that contains bone; collecting the pure meat into a container; and transferring the meat that contains the bone to the secondary meat grinder unit. The secondary meat grinder unit is designed to further grind the batch of meat by separating additional pure meat from the meat that contains the bone; collecting this additional pure meat into the container with the original pure meat; and discard any remaining “undesireables”. The meat grinding reclaiming system also provides an inventive variable valve reducer for controlling the flow of the undesireables through the secondary transfer pipe.
