Studies on the Optimum Conditions for Rice Post-harvest Processes in Developing Countries (Part 2)

Husking Properties of Impeller Type Husker and Changes of Brown Rice Quality During Storage

Abstract

A large amount of grain loss frequently occurs in developing countries especially in South-east Asia due to inappropriate post-harvesting processes. In our previous report, the influence of the drying conditions on husking properties using the rubber roll type husker was mentioned. Compared with the rubber roll type, the impeller type husker has additional advantages such as stable husking rate and easy maintenance. Therefore, we considered the possibility of introducing the impeller type husker to developing countries. In this research, the correlation of drying and husking conditions with quality of brown rice were examined using the rubber roll and impeller type husker. The results showed that the impeller type husker is useful from the viewpoints of stability of husking rate and high power efficiency.
