Abstract. In the U.S., there is still an ongoing debate on the relevance of fluidized bed drying techniques for rough rice. This debate resulted in a lack of information on the effects of utilizing fluidized bed technique to dry rough rice on its pasting properties. Successful improvements to the fluidized bed drying technique through this study can provide an option for U.S. rice farmers for faster and continuous drying. The current study aimed to study the effects of air temperature (40°C and 50°C), dehumidification (yes, and no), and drying duration (30 min and 60 min) on the pasting properties and moisture removal of rice. The experiments took place under fluidized bed conditions. Silica gel was used as a desiccant for ambient air dehumidification. Ambient air dehumidification improved moisture removal and can be employed by the farmers during humid conditions. Pasting properties supported the notion of attaining good quality rice from fluidized bed drying of rice. Overall, fluidized bed drying of rice can be used without compromising the rice quality.
