Solution Overview

Problem

Conventional pork rind production methods are inefficient due to lengthy rendering processes, which limit the number of batches that can be processed in a day, leading to increased costs and reduced productivity, as each batch requires significant time to render and polish before the next can be started.

Innovation Solution

A batch rendering system comprising multiple rendering tanks, a conveyor, and a polishing tank, where pork skins are cooked and then transferred to the conveyor for polishing, allowing simultaneous processing of multiple batches and enabling the rendering tanks to prepare for the next batch while the previous is being polished, thus reducing overall batch time and increasing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional single-batch rendering and polishing is used, then processing simplicity is maintained, but productivity is limited and batch time is excessive (360 minutes per batch)

Engineering Contradiction:
Improvenumber of batches processed per dayVSAvoidbatch processing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent divides the rendering process into two independent parallel lines, each with its own rendering tank and polishing tank. This segmentation allows simultaneous processing of multiple batches, increasing productivity from one batch every 360 minutes to two batches every 290 minutes, effectively reducing the time loss per batch while maintaining processing simplicity through modular duplication.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple rendering tanks and polishing tanks are used simultaneously, then productivity increases, but device complexity increases

Engineering Contradiction:
Improvenumber of batches processed per dayVSAvoidnumber of tanks and conveyors
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is segmented into identical, independent modules (rendering tank + polishing tank pairs), which simplifies the complexity management by using repetition of standardized units rather than creating a complex integrated system. This modular approach allows productivity increase while keeping each module relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines rendering and polishing operations into integrated pairs of tanks that work simultaneously, with conveyors linking them. This merging of functions into coordinated units increases productivity while maintaining operational simplicity through the unified render-polish cycle, rather than having separate independent processes.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of time

If rendering and polishing are performed sequentially in the same tank, then device complexity is minimized, but loss of time increases due to inability to overlap operations

Engineering Contradiction:
Improvewaiting time between batchesVSAvoidseparation of rendering and polishing equipment
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

By separating rendering and polishing into different tanks that operate in parallel, the system eliminates the sequential waiting time where a single tank would need to complete rendering before starting polishing. The segmentation allows overlapping operations across multiple tanks, reducing total cycle time from 360 minutes to 290 minutes per batch.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary rendering in dedicated rendering tanks before transferring to polishing tanks, allowing the rendering phase to be completed in advance while polishing occurs simultaneously in separate equipment. This preliminary action in dedicated tanks enables overlapping of operations and reduces overall waiting time.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system has rendering tanks, a polishing tank, and a conveyor associated with the rendering tanks and the polishing tank. A batch rendering method for producing pork rinds with the system includes: (a) loading a first batch of pork skins into the rendering tanks; (b) cooking the first batch of pork skins inside the rendering tanks; (c) unloading the first batch of pork skins from each of the rendering tanks into the conveyor; (d) transporting the first batch of pork skins to the polishing tank; (e) loading the first batch of pork skins into the polishing tank; (f) tumbling the first batch of pork skins within the polishing tank; (g) loading a second batch of pork skins into the rendering tanks; and (h) cooking the second batch of pork skins inside the rendering tanks. Steps (f) and (h) occur at the same time.
