The invention relates to an implementation method for integrated food processing. A tank cover is provided with a feed inlet. A spiral separation plate is arranged in an oil tank. Three oil speed regulation mechanisms are arranged on a spiral oil way from an oil inlet of the oil tank and an oil outlet of the oil tank. An oblique plate is fixedly arranged at a position, located at the oil outlet, in the oil tank. A feed rotating shaft is connected to the middle of the oblique plate rotationally and is connected with an arc-shaped strainer. A discharge channel is formed in a position, above a conveying mesh belt, of the oblique plate. A screen is arranged below the discharge side of the conveying mesh belt. A roller is arranged above the middle of the screen and is internally provided with a cavity used for holding cumin powder. A plurality of discharge through holes are formed in the roller radially and are communicated with the cavity of the roller. The implementation method has the advantages of simple structure, convenience in operation, high integration degree and capability of meeting production requirements of food industry effectively.
