PERFORMANCE CONTROL FOR SAFE AND PRECISION SOLAR DRYING OF CURATIVE AND AROMATIC HERBS

摘要

Generally, through knowledge and skills it is possible to increase precision and effectiveness of technology application. Sustainability, marketing and economic returns are valuable issues that rural communities should carefully engage when processing and adding value to herbs, plants and bushes through solar drying in order to obtain key components used in the medical and aromatic industries. The glasshouse 240 m~3 capacity provided sufficient hot air up to 70°C to the drier. Drier performed effectively when its 5.8 m~2 drying area is being safely controlled either entirely or by any of its individual sections. A full batch of same type herb material was loaded in the drier and it took 8 hours to reduce moisture content from 25% to 12%. It was recorded that yield of active ingredients was increased 30%, enhancing its quality and purity and losses were measured for undesirable varying temperatures, as well as influenced and technical factors that require improvement.
