The patent describes a highly integrated bean roasting system designed to efficiently treat multiple exhaust and fluid streams through a shared thermal and filtration hub.
Award-Winning Innovation
This system has been named Swanson Reed’s Patent of the Month in the Food and Beverage industry for February 2026. It earned this recognition because it is an outstanding invention that significantly advances sustainable, emission-controlled roasting mechanics by streamlining complex thermal management.
Patent Abstract
A bean roasting system includes a roasting drum, an air handling system, a bean cooler, and an air exit subsystem. The air exit subsystem is configured to receive and treat a first fluid stream from the air handling system and a second fluid stream from the bean cooler. The air exit subsystem includes a heat sink and a filter. The heat sink defines two parallel fluid paths including a first fluid path and a second fluid path. The air exit subsystem includes a metal body configured to receive heat from the first fluid path and the second fluid path. The first fluid path is fluidically coupled to receive the first fluid stream from the air handling system. The second fluid path is fluidically coupled to receive the second fluid stream from the bean cooler. The filter is fluidically coupled to the first and second air flow paths.
Meeting the U.S. R&D Tax Credit Rules
To qualify for the U.S. Research and Development (R&D) Tax Credit, an innovation must satisfy the IRS’s “Four-Part Test.” Here is how Bellwether Coffee Co.’s development process for this patent aligns with those requirements:
- Permitted Purpose: The research intended to create a new or improved business component. By developing a unified air exit subsystem, Bellwether aimed to improve the system’s performance, energy efficiency, and environmental footprint.
- Technological in Nature: The development process fundamentally relied on the principles of hard sciences—specifically mechanical engineering, thermodynamics, and fluid dynamics—to design the complex heat sink and parallel fluid paths.
- Elimination of Uncertainty: At the outset of the project, there was technical uncertainty regarding the optimal design, methodology, or capability of combining distinct exhaust streams (from the roasting drum and the cooler) into a single filtering and cooling body without causing equipment failure or airflow backpressure.
- Process of Experimentation: The engineering team engaged in iterative testing, evaluating various metal body configurations, simulating airflow, and prototyping to achieve the final, functional design outlined in the patent.
3 Practical Applications Qualifying for R&D Tax Credits
- Thermal Management Prototyping: Designing, building, and physically testing prototypes of the metal body heat sink. This experimentation is required to determine the precise material composition and structural thickness necessary to absorb and dissipate extreme heat from two parallel fluid paths simultaneously without structural degradation.
- Fluid Dynamics Simulation and Testing: Conducting computational fluid dynamics (CFD) modeling and physical airflow stress tests. Engineers would need to test different internal routing designs to overcome uncertainties in merging the first fluid stream (roaster exhaust) and the second fluid stream (cooler exhaust) through a single filter without cross-contamination or choking the system.
- Emissions Filtration Optimization: Iteratively evaluating and testing various filter media and form factors. This process ensures the single filter, which is fluidically coupled to both airflow paths, can successfully handle the combined flow rate and meet stringent volatile organic compound (VOC) and smoke reduction targets during active roasting cycles.
