Production method of distiller's dried whole grains of paddy rice

The invention discloses a production method of distiller's dried whole grains of paddy rice. The production method comprises the following steps: (1) pulverizing paddy rice raw materials and performing fermentation; (2) rectifying the fermentation finished mash to extract alcohol and obtain a paddy rice alcohol waste mash; (3) performing separation on the waste mash liquid using a plate and framefilter press; (4) performing drying on separated paddy rice wet distiller's grains using a roller dryer, and allowing clear liquid to enter an evaporation concentration system to prepare concentratedliquor; and (5) performing dry mixing on the concentrated liquor of the clear liquid and the paddy rice wet distiller's grains and performing drying and pulverizing. The production method of the distiller's dried whole grains of paddy rice has the beneficial effects: 1, by using the preparation method disclosed by the invention, the distiller's dried whole grains of paddy rice are produced from the paddy rice waste mash li
