“…Currently more and more renewable energy-based drying systems are being developed. Some developed a foodstuff drying system [1], elaborated a cocoa beans drying system [2], evolved a wood drying system [3,4], promoted a shoe drying system [5], extended a biomass-energized drying system [6,7], unfolded a cloth drying system [8], developed the radio frequency and microwave heating treatment to disinfest "kutu beras" [Sitophilus oryzae (Linnaeus, 1763)] [9], development of building rehabilitation with dry and wet systems [10], promoted of heating zone temperature control for the drying process [11], and development of the solar-energized drying system [13]. Hence the development of a drying system using this renewable energy source, becomes a challenge and also a solution to improve economy and prepare for facing increasingly fierce competition.…”
