A study of infrared radiation heating for potato peeling

บทคัดย่อ

This research studied the thermal of infrared radiation for peeling the potato. Infrared radiation machine was built to use the heat by infrared radiation which 2 - 10 µm. The power level used 840 and 905 Watt and the heating times were set 105, 115, 125 and 135 seconds. The objective of this research was studied the feasibility of using infrared radiation for peeling the potato and the effects of heating temperature after peeling. The results of the experiment found that the power level of 905 W and the heating times of 135 seconds were peeling ability of 100% and very easiness for peeling. The surface temperature of IR heated potato was 157°C and little impacted on potato quality.
