Radial Turnover Stirring Blade for Low-Oil Uniform Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deep fryers require large quantities of oil, leading to handling difficulties, safety risks, high costs, and environmental concerns, while existing stirrer systems are inadequate for uniform cooking of fragile or changing consistency foods.
Innovation Solution
A cooking appliance with a receptacle and a blade designed for relative rotary motion to stir food, featuring turnover means that cause food to turn over radially, ensuring uniform coating and heating without immersion in a large oil bath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional deep fryers use large quantities of oil for complete immersion frying, then uniform cooking is achieved, but handling difficulties and safety risks increase
Solution Approach 1:
The invention extracts the food from the large oil bath environment and places it in a controlled pan-frying environment with minimal oil. The stirring mechanism actively manages the cooking process, replacing the passive immersion approach with an active, controlled system that uses far less oil while maintaining cooking effectiveness.
Solution Approach 2:
The invention introduces dynamic stirring motion to compensate for the reduced oil quantity. The stirring mechanism continuously moves the food, ensuring uniform exposure to heat and oil, replacing the static immersion environment with a dynamic cooking process that achieves similar uniformity with less oil.
2Reliability
If conventional deep fryers use large quantities of oil, then cooking bath is maintained, but pre-heating time increases and safety risks increase
Solution Approach 1:
The invention extracts the cooking process from the large oil bath paradigm, using only the minimum oil necessary for pan-frying. This eliminates the need to heat large volumes of oil, dramatically reducing pre-heating time while maintaining cooking effectiveness through active stirring and controlled heat application.
3Reliability
If conventional deep fryers use large quantities of oil, then frying is achieved, but oil consumption costs increase
Solution Approach 1:
The invention extracts the essential frying function from the large oil bath requirement, achieving effective frying with minimal oil through active stirring. This separates the core frying objective from the excessive oil consumption, maintaining cooking quality while dramatically reducing oil usage.
Solution Approach 2:
The stirring mechanism continuously redistributes the food and oil, ensuring that the minimal oil present is efficiently utilized across all food surfaces. This self-managing system maximizes the effectiveness of the small oil quantity, eliminating waste and reducing consumption.
4Reliability
If conventional deep fryers heat large quantities of oil to high temperature, then frying is achieved, but disagreeable smells are produced
Solution Approach 1:
The invention extracts the frying process from the large oil volume environment, heating only the minimal oil necessary for cooking. This dramatically reduces the total oil being heated to high temperatures, thereby reducing the generation of disagreeable smells while maintaining frying performance through active stirring.
5Reliability
If conventional deep fryers heat large quantities of oil, then cooking is achieved, but oil polymerization occurs and cleaning becomes difficult
Solution Approach 1:
The invention extracts the cooking process from the large oil bath environment, using minimal oil that is continuously stirred and distributed. This prevents the localized overheating and polymerization that occurs in large oil volumes, and the small amount of oil used is much easier to clean from the cooking surface.
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
The appliance achieves uniform cooking of food with reduced oil usage, preventing food from sticking and ensuring organoleptic qualities similar to deep-fried foods without full immersion, while being compact, inexpensive, and easy to use.
Implementation Method 1
