PURPOSE:To obtain rice flour, excellent in processing characteristics and quality and useful as rice confectionery, etc., with hardly any damaging degree of starch by carrying out hydrating operation such as washing of rice with water and dipping thereof in water, coarsely crushing the resultant dipped rice with a roll flour mill and further finely pulverizing the crushed rice with an air stream pulverizer. CONSTITUTION:Rice flour is produced from rice grains. In the process, hydrating operation such as washing of rice with water and dipping thereof in water is performed to prepare dipped rice, which is then coarsely crushed with a roll flour mill and further finely pulverized in an air stream pulverizer (at 7000r.p.m. rotor speed and about 30kg/hr sample feed rate) so to as to provide <=5% damage degree of starch in the rice flour and >=90% fraction passing through a 200-mesh screen. Thereby, the objective rice flour is obtained. |
