Puffed coarse grain food producing method

The invention discloses a puffed coarse grain food producing method. The puffed coarse grain food producing method comprises the following steps: carefully selecting pop rice for use; baking and frying peanuts, and carefully selecting and crushing the peanuts for use; baking and frying sesame seeds; adding white sugar, palm oil, maltose syrup and salt water, heating and boiling sugar; mixing prepared materials, and frying and molding the materials to obtain the puffed coarse grain food; packaging internally; bagging and measuring; sealing and boxing; and detecting metals. According to the technical scheme, the formulation is optimized and stable; a product is good in reproducibility; after batch production, the cost can be reduced and the mouth feel is correspondingly stable; furthermore, after automatic extrusion molding, the production efficiency can be improved and the labor cost can be saved; and in addition, a metal detector is used for detection, so that whether fragments of metal substances are left in the product due to tool damage of an automatic molding machine and other reasons can be detected, thus avoiding the quality problem of the product.
