Abstract

A continuous process for parboiling of brown rice suitable for adoption in small to medium scale processing operations is described. Brown rice obtained from a commercial type of paddy (var. IR 20) was soaked at ambient conditions and roasted in a continuous roaster commonly used for frying Bengal gram. The roaster was modified by interchanging the path of movement of rice-sand mixture to overcome the problem of non-uniform parboiling, excessive puffing and charring of grains. Studies indicated that using the modified roaster, soaked brown rice (moisture content 32%) could be roasted to obtain a uniformly parboiled product at a rice-sand temp. of around 120-130C in about 30 s; equilibrium moisture content of parboiled rice was approx. 50%.
