Processing technology of rice with bright and clean appearance and low broken rice rate

The invention discloses a processing technology of rice with a bright and clean appearance and a low broken rice rate. The processing technology comprises the following steps that a teflon lining is fixed into the inner wall of a reaction box with better sealing property, and ferric chloride, Arabic gum and ethylene glycol are sent into the reaction box to be evenly dispersed; the reaction box issealed, and then the reaction box is placed in a heating box to be heated and reacted; the reaction box is firstly subjected to magnetic separation, then washed and finally subjected to spray drying to obtain a magnetic adsorption material; and dry unhulled rice is added into the magnetic adsorption material and stirred uniformly, cooling stirring is performed, and pretreated unhulled rice is obtained. The processing technology changes the conditions that the water content of brown rice is low and a large amount of broken rice is generated during processing. The brown rice is subjected to atomizing, dampening and brow
