Abstract: A device for providing a measured portion of food product on demand in which a portioned metering head has an inlet to receive the food product under pressure and an outlet to discharge the food product onto the food-receiving medium. There is a disk in the housing which has a disk passageway connecting the inlet and outlet passageways of the metering head. Within the disk passageway is a piston which can slide from one end to the other. By rotating the disk, the food product pushes against the piston causing it to push the food product previously within the disk passageway out into the outlet passageway of the metering head. The cycle repeats with the disk rotating 180.degree., once again positioning the piston adjacent to the inlet passageway. A photoelectric eye signals a control mechanism and connected air cylinder to rotate the disk each time a food-receiving medium is disposed under the metering head.
