Solution Overview
Problem
Conventional meat smokers using compressed hardwood pellets face issues with rapid degradation and dust formation due to elevated temperatures, leading to inconsistent smoke generation and surface contamination.
Innovation Solution
A smoke generating assembly with a smoldering chamber and rotating auger system that advances combustible material past a smoldering heater, incorporating an igniter gap to separate and manage pellet dust, ensuring controlled smoke generation and temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If hardwood pellets are used as fuel in elevated temperature smokers, then smoke generation is achieved, but pellet degradation and dust formation increase rapidly
Solution Approach 1:
The system separates pellet dust management from the main combustion chamber by introducing a dedicated dust collection tray positioned below the burn pot. This segmentation allows dust to be collected and removed separately from the fuel combustion process, addressing the degradation issue without compromising smoke generation temperature.
Solution Approach 2:
A dust collection tray acts as an intermediary component between the burn pot and the external environment. This intermediary structure captures falling pellet dust before it can contaminate surrounding surfaces or interfere with the smoking process, while maintaining the necessary high temperatures for smoke generation.
2Productivity
If pellet dust accumulates on surfaces and water reservoirs, then smoke generation continues, but surface contamination and combustion consistency deteriorate
Solution Approach 1:
The system extracts the harmful pellet dust from the smoke generation environment by providing a dedicated collection tray. This removes the contaminant from the system before it can affect surfaces or water reservoirs, while maintaining continuous smoke production from the clean fuel source in the burn pot.
Solution Approach 2:
The dust collection tray converts the harmful effect of falling pellet dust into a manageable byproduct that can be easily removed. By providing a designated collection area, the system transforms the contamination problem into a simple maintenance task, ensuring continuous clean smoke generation.
3Duration of action of moving object
If pellets are exposed to elevated temperatures for extended periods, then smoke production is maintained, but pellet moisture loss and breakdown increase
Solution Approach 1:
The system performs preliminary separation of dust from the fuel supply path. By collecting dust before it can fall back onto the fuel source or into water reservoirs, the system maintains fuel integrity and moisture content for longer periods, enabling sustained smoke generation without rapid pellet degradation.

Function Achieved in This Case
This solution provides improved temperature control and reduced pellet dust accumulation, resulting in consistent smoke generation and enhanced cooking performance by smoldering combustible materials efficiently while minimizing ash formation and surface contamination.
Implementation Method 1
a smoldering heater positioned adjacent the smoke barrel for smoldering the combustible material as the auger advances the combustible material past the smoldering heater
Implementation Method 2
an auger positioned within the smoke barrel and being rotatable about the central axis for selectively urging the combustible material from the first end toward the second end of the smoldering chamber
Data Source
AI summary
A smoke generating assembly for an indoor smoker includes a smoke barrel having a rotating auger positioned therein. The smoke barrel may be supplied with combustible material at a first end of the smoke barrel and the auger may be intermittently rotated to advance the combustible material toward a second end of the smoke barrel and over a smoldering heater to generate a flow of smoke. The smoldering heater may be spaced apart from the smoke barrel by an igniter gap that permits pellet dust from the combustible material to fall into the container below, leaving only solid combustible material to pass through the smoldering heater for combustion.
