Barbecue grill accessory and method for preparing food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbecue grills lack the capability to efficiently achieve both slow smoking and fast hot searing techniques within a single cooking session, as they often result in temperature inconsistencies and inefficient heat distribution.
Innovation Solution
A grilling insert with a double-wall thermal barrier and radiant heat chamber is used to divide the cooking chamber into direct-heating and indirect-heating sections, allowing for adjustable temperature control by using a chordal water reservoir and charcoal briquettes, enabling both low-temperature slow smoking and high-temperature searing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional barbecue grills are used for both slow smoking and fast hot searing, then temperature inconsistencies occur, but using separate equipment would enable both techniques
Solution Approach 1:
The cooking chamber is divided into two distinct zones by the double-wall thermal barrier: a direct-heating section for high-temperature searing and an indirect-heating section for low-temperature smoking. This spatial segmentation allows both grilling techniques to occur simultaneously in the same grill without temperature interference.
Solution Approach 2:
The double-wall thermal barrier acts as an intermediary structure between the heat source and the cooking areas. It selectively directs and filters heat to create different thermal environments in different sections, enabling the grill to perform both smoking and searing functions.
2Productivity
If high heat is applied for fast hot searing, then cooking speed increases, but temperature control for slow smoking becomes difficult
Solution Approach 1:
Different sections of the cooking chamber are provided with different thermal characteristics: the direct-heating section receives intense radiant heat for rapid cooking, while the indirect-heating section receives filtered, gentler heat for slow cooking. Each zone is optimized for its specific cooking requirement.
Solution Approach 2:
The system allows dynamic selection of cooking modes by adjusting the placement of food items in different sections and controlling the heat source configuration. The thermal barrier dynamically directs heat flow based on the cooking requirements of each zone.
3Device complexity
If a single cooking chamber is used for both smoking and searing, then equipment simplicity is maintained, but heat distribution efficiency decreases
Solution Approach 1:
The cooking chamber is segmented into direct and indirect heating zones using a double-wall thermal barrier, allowing efficient heat distribution to different areas. This segmentation enables the grill to optimize heat usage for different cooking techniques without requiring separate equipment.
Solution Approach 2:
The grill structure is designed to perform multiple functions (smoking, searing, roasting) within a single chamber by using the thermal barrier to create different heating zones. This multi-functionality maintains equipment simplicity while improving heat distribution efficiency for various cooking requirements.
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
This setup provides improved temperature control and stability, allowing for consistent cooking temperatures between 225°F and over 1000°F, enhancing flavor and tenderness of smoked meats while maintaining temperature consistency for extended periods.
Implementation Method 1
The double-wall thermal barrier is adapted for extending across the recessed cooking chamber of the barbecue grill, and for dividing the cooking chamber into direct-heating and indirect-heating cooking sections. The cooking temperature in the direct-heating cooking section is relatively high, and is reduced in the indirect-heating cooking section by the double-wall thermal barrier.
Implementation Method 2
The thermal barrier comprises a chordal water reservoir designed to extend from one point on a circular interior of the recessed cooking chamber to an opposite point.
Implementation Method 3
The radiant heat chamber is formed adjacent the double-wall thermal barrier, and is designed for holding loose combustible material within the direct-heating cooking section of the barbecue grill. The cooking temperature in the direct-heating cooking section is relatively high.
