Economic evaluation of padi drying using heat from powertiller

Ooi Ho Seng

Abstract

At the present stage of research and development work on waste engine heat drying, it was felt that an economic reappraisal of the project was necessary to justify the continuation of the work. The problems associated with the deterioration of off-season paddy was discussed and the value of the losses was estimated at $160 per farmer per season. The cost of waste engine heat drying to overcome these losses was estimated at $79.42 per farmer per season or $13.24 per ton of paddy. It was noted that there will be a significant savings to the farmers and the nation if appropriate on-farm drying were carried out.
