A Study and Development of the Control System of Fruit Dehydration Machine by Biomass Energy

This article presents the study and development of the control system of fruit dehydration machine by biomass energy in which manual control system was upgraded to the Auto one. Study results revealed that Auto control system required less operation time for as much as 1.30 hour. By comparing energy consumption of the two systems, the upgraded system required less energy approximately 751.30 baht/month and 9,016.32 baht/year. When the break-even point is taken into consideration, this system upgrade could payback after 3.33 year. The author really hopes that this study can be used as a guideline for those interested or involved in the development fruit dehydration machine.
