Indonesia: Biomass-Powered Vacuum Drying System

Meeting Time

Thursday 7pm

Project Description

Indonesia’s coffee industry faces challenges in post-harvest processing, particularly with sun drying, which is highly dependent on weather and can lead to inconsistent quality and spoilage. A promising solution is a biomass-powered high-efficiency vacuum dryer, which utilizes locally abundant biomass resources such as coffee husks, cattle manure, and leaf litter. By converting these agricultural by-products into fuel, the system generates heat for the drying process, significantly reducing reliance on fossil fuels or electricity. The vacuum drying technology lowers the pressure in the drying chamber, allowing coffee beans to dry at lower temperatures, preserving their flavor and quality. This method ensures uniform drying and faster processing times, which reduces the risk of mold or contamination and increases throughput. The use of biomass as an energy source makes the system cost-effective, as it repurposes waste materials and cuts down on fuel expenses. Additionally, this technology supports sustainable agriculture by reducing waste, lowering carbon emissions, and improving the economic resilience of coffee farmers.​
