A method is described for measuring the bulk compression modulus of brown rice grains and its variation with time of loading. Rice grains of variety IR‐8 at four various moisture levels from 12–29% (db) were subjected to a maximum pressure of 1.38 × 10 7 N/m 2 . Values of bulk creep modulus and its inverse, bulk creep compliance, at various levels were determined. The rheological model proposed for the bulk creep behavior of rice grains was a three element truncated Burger's model.
