Solution Overview

Problem

Conveyor belt-based systems for treating food products with a specific weight greater than oil face issues with whirlpools, which cause uneven treatment due to varying residence times and detachment of products, primarily attributed to suboptimal oil supply methods.

Innovation Solution

The implementation of a metering device with adjustable passage openings and multiple supply ducts, strategically positioned to ensure a steady and uniform oil supply, reducing whirlpool occurrence and allowing for precise temperature control and consistent treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If oil is supplied via a conventional supply passage, then the system structure is simple, but whirlpools occur causing uneven treatment and varying residence times

Engineering Contradiction:
Improveuniformity of treatmentVSAvoidsupply system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The supply passage is divided into multiple separate supply ducts (at least two) that are distributed across the container width. Each duct receives oil from separate inlets and supplies it to different locations in the bath, preventing the formation of whirlpools and ensuring uniform oil distribution and consistent treatment of food products throughout the bath.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the oil supply are optimized for different functions: multiple supply ducts are positioned at specific locations to create localized steady flow zones, while metering devices are placed at each duct to independently control oil flow rates. This ensures that each region of the bath receives appropriately controlled oil supply, preventing whirlpools and ensuring uniform treatment.

Inventive Principle:
Principle #3Local quality

2Temperature

If a single supply duct is used, then the device complexity is low, but the temperature control accuracy and heat input uniformity are poor

Engineering Contradiction:
Improvetemperature control accuracyVSAvoidsupply body structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The single supply duct is segmented into multiple supply ducts (at least two), each equipped with its own metering device. This segmentation allows independent control of oil flow to different regions of the bath, enabling precise temperature control and uniform heat input across the entire oil bath while maintaining consistent treatment conditions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Metering devices are incorporated into each supply duct to dynamically adjust and control the oil flow rate. This dynamic control capability allows for precise regulation of oil supply to maintain optimal temperature and ensure uniform heat input, adapting to varying operational requirements while preventing whirlpool formation.

Inventive Principle:
Principle #15Dynamics
