Net Receptacle Insert for Convection Ovens With Fewer Carbon Specs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convection ovens using fast-moving hot air for food preparation experience the formation of carbon particles, known as carbon specs, which adhere to food and foul the oven and preparation basket, leading to uneven cooking and increased cleaning frequency.
Innovation Solution
A convection oven with a rotatable, air-permeable preparation basket and a non-stiff receptacle featuring a net structure with through holes and a non-stick surface to minimize carbon spec adherence, allowing circulating air to pass through and reducing their deposition on food.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a solid preparation basket is used to hold food during convection cooking, then the food is supported and contained, but carbon specs accumulate on the food and basket surface requiring frequent cleaning
Solution Approach 1:
The preparation basket is constructed with a net structure containing numerous through-holes that allow circulating air to pass through freely. This porous configuration prevents carbon specs from accumulating on the basket surface while maintaining the basket's ability to support and contain the food during convection cooking
Solution Approach 2:
A receptacle with a non-stick coating is introduced as an intermediary between the food and the preparation basket. This receptacle prevents carbon specs from transferring to the food while allowing air circulation through the net structure, and facilitates easy removal of any adhered specs during cleaning
2Ease of operation
If the preparation basket is made solid to contain food, then food containment is improved, but air circulation is blocked reducing cooking efficiency
Solution Approach 1:
The preparation basket employs a net structure with numerous through-holes that provide adequate food containment while allowing fast-moving hot air to circulate freely through the basket, maintaining cooking efficiency without sacrificing food support capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces carbon spec deposition on food, enhancing cooking quality and simplifying cleaning by allowing air to circulate freely and facilitating the removal of adhered specs from the receptacle.
Implementation Method 1
a fan arranged to circulate hot air within said oven compartment
Implementation Method 2
convection oven is an oven that imparts heat onto the food to be cooked by use of fast moving hot air
Implementation Method 3
the receptacle comprising a non-stiff receptacle wall at least partly formed by a net structure with through holes... allowing air to circulate freely through the preparation basket and around the food
