Renewable energy-based drying medicinal plants Project Details
| Abstract |
This project develops and tests a renewable‑energy drying system made for medicinal plants. The aim is to dry quickly, keep phytochemicals intact, and preserve overall product quality. Open‑sun drying often contaminates the material and breaks down heat‑sensitive compounds. Dryers that run on fossil fuels are costly to operate and have a large environmental impact. To solve these problems, the system combines a solar‑thermal collector with a biomass backup heater, allowing continuous and controlled drying. A network of sensors tracks temperature, relative humidity, and airflow rate so the drying conditions stay optimal. By managing the chamber’s microclimate, the system reduces thermal loss of essential oils and active pharmaceutical ingredients. The project
provides step‑by‑step guidance on designing the thermal system, integrating the sensors, and measuring drying curves. With this support, students can evaluate moisture‑removal rate, thermal efficiency, and quality parameters of the dried herbs. The result is a sustainable, low‑cost post‑harvest processing method that links renewable‑energy engineering with pharmaceutical quality preservation.
