Seed drying to suitable moisture content during harvesting immediately and storage is a key factor to maintain a long-shelf life. The purpose of this research was to use the zeolite drying beads to dry rice seeds var. Phitsanulok 2 (PSL2) and Ayutthaya 1 (AYT1) to target moisture content at 6 % and 12 %. Three experiments were carried out at Prachinburi Rice Research Center during April 2012- January 2013. Rice seeds with the different initial moisture content were blended with three beads to seed ratios at 30oC, 40oC and ambient temperature. The results revealed that rice seed moisture content could be reduced to the target moisture content which depended on variety, initial moisture content, the bead-to-seed ratio, drying temperature and drying... |
