Replication of Dryve: Encapsulated Drying Machine for Faster Organic Fertilizer Decomposition for Residential Areas (2025)

Abstract

Drying machine offers an alternative to sun-drying, which can take months and is often hindered by unfavorable weather conditions. However, existing drying machines are primarily designed for large-scale farms or industry. This study presents an improved small-scale drying machine suitable for residential areas. Through a series of experiments, the machine’s performance and efficiency in drying organic waste were evaluated. The results show that the machine is durable and achieves an optimal drying time of up to 2 hours and 45 minutes at 110°C while consuming only 0.85 kilowatts per hour. Furthermore, thermal and airflow analysis showed uneven heat distribution depending on the type of waste, resulting in varying moisture content removal across the different layers of the drying rack. Specifically, temperature of 110°C achieved moisture content removals 16-64%, 53-88%, 56-94%, 45-86%, 91- 97%, and 88-96% respectively. In general, this innovative small-scale drying machine enables residents to efficiently dry organic waste and produce their own fertilizers, enhancing fruit and vegetable yields, and promoting sustainable waste management practices.
