The dual-drum coffee roaster is a 500-gram tabletop machine designed specifically for home users and small businesses. Its twin-drum design allows users to choose between single or dual-drum roasting, minimizing coffee bean waste and energy consumption during small-batch roasting. Featuring a modular structure, users have the option to integrate a semi-automatic packaging unit to ensure that cooled coffee beans are freshly packed, avoiding prolonged storage and preserving their flavor. The integrated aroma tagging system employs a scent detection chip positioned at the exhaust outlet to analyze the molecular composition of coffee aromas during the roasting process. This reduces human error and lowers the expertise required for flavor evaluation. Additionally, with the support of an AIoT-based digital traceability system, consumers can scan a code to access detailed coffee bean information, enhancing overall product credibility.
