On the Equilibrium Relationship between Moisture-Content of Brown Rice and Humidity in a Warehouse

Abstract

In consequence of the experiments on brown rice of different physico-chemical rquality stored for the period from January to October at 14 places different in climatic conditions in Japan, the following equilibrium relationship was found between the average relative humidity (f) during storage and the moisture-content (c) in brown rice determined immediately before storing. c=5.05+0.13 f where 60 % < f < 82 % In order to improve the delivery of brown rice, further accurate and minute studies as the above, are necessarye.
