Solution Overview

Problem

Existing industrial ovens focus primarily on optimizing heat transfer mechanisms while neglecting the evaluation of baking results such as specific volume, crust thickness, pH, color, and chemical-physical features of foodstuffs, and are often designed for a single type of foodstuff, limiting flexibility and adaptability to diverse baking needs.

Innovation Solution

An industrial oven with a vertical single chamber using chain transport means and a circulation assembly that generates baking air jets and saturated steam to optimize heat penetration and baking quality, allowing for varied baking diagrams and reduced energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional heat transfer optimization is used, then heat transfer efficiency is improved, but baking quality parameters (specific volume, crust thickness, pH, color) are neglected and energy consumption is not optimized

Engineering Contradiction:
Improveenergy consumptionVSAvoidbaking quality parameters
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The system incorporates sensors that continuously monitor baking quality parameters (specific volume, crust thickness, pH, color) and feed this information back to the control unit. The control unit adjusts heat transfer mechanisms based on this feedback to optimize both energy consumption and baking quality, resolving the contradiction between energy efficiency and quality control

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The oven integrates multiple functions into a single system: heat transfer optimization, real-time quality parameter monitoring, and adaptive control. This multi-functional approach allows simultaneous optimization of energy consumption and baking quality without requiring separate systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the oven is designed for a single type of foodstuff, then heat transfer can be optimized for that specific product, but flexibility and adaptability to diverse baking needs are limited

Engineering Contradiction:
Improveflexibility for diverse foodstuffsVSAvoidbaking result consistency
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system dynamically adjusts heat transfer parameters, air jet configurations, and steam injection rates based on the specific foodstuff being baked. The control unit modifies operational parameters in real-time according to the product type, maintaining baking precision while achieving versatility across different foodstuffs

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The oven changes operational parameters (temperature, humidity, air flow velocity, steam injection rate) according to the specific baking requirements of different foodstuffs. This parameter adaptation allows the system to maintain high baking quality across diverse products while being flexible to changing needs

Inventive Principle:
Principle #35Parameter changes

3Productivity

If baking time is reduced by 10%, then productivity is improved, but energy consumption must be carefully managed to maintain baking quality

Engineering Contradiction:
Improvebaking speedVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic steam injection and pulsed air jets during the baking process to enhance heat transfer efficiency. This periodic action intensifies heat penetration during critical phases, allowing reduced overall baking time while maintaining quality and managing energy consumption effectively

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system utilizes phase transitions of water (liquid to vapor) through steam injection to rapidly transfer heat to the foodstuff. This phase change mechanism provides intense heat transfer in short duration, enabling reduced baking time with controlled energy input while maintaining baking quality

Inventive Principle:
Principle #36Phase transitions
