This paper proposes a low-cost herb dryer using infrared lamps with circulating hot air blowers. Detailed design, development and evaluation of the proposed dryer prototype were presented. The raw herbs from Rai Sodsai Thai Wapi Herb Farm, a well-known, local social entrepreneurship model for massive herbal production for Maha Sarakham city, Thailand. Three important herbs: Curcuma Longa Linn, Curcuma Aromatica, and Curcuma Comosa Roxb were used to evaluate the performance of the proposed dryer prototype compared to the traditional sun drying. The experimental test results showed that the proposed dryer achieved reducing drying time from 3-5 hours to be about 4-6 hours. and provided the best quality with the controllable drying temperature in the range of 55-60 oC, which could not be easily achieved with the traditional sun drying that the farm currently used.
