A freeze cylinder includes a scraper/mixing element having two rotating scraper mounting rods secured at opposite ends thereof to common spanning members. Each spanning member has a central pivoting mounting point for providing pivotal mounting thereof within the freeze cylinder. A scraper blade is secured to each of the scraper mounting rods. An eccentric shaft extends through the cylinder, offset from a central axis thereof and each end thereof extends is retained within a respective central pivoting mounting point of the spanning members. An auger section extends from one of the spanning sections for positioning thereof at a dispense end of the cylinder adjacent a dispensing valve. The scraper blade is used in the context of a semi frozen food product making and dispensing machine. In operation, a drive means provides for rotating the spanning members and hence the scraping blades and auger section within a food product producing freeze cylinder. The blades provide for harvesting semi-frozen food product from the interior surface of the freeze cylinder. As such are being rotated, the eccentric shaft remains motionless and offset form the central axis of the cylinder. Thus, as the drink is being formed, the eccentric shaft provides for additional mixing thereof as it is forced there against and made to flow there around. In this manner, better uniform drink viscosity consistency is provided for throughout the interior volume of the cylinder. When dispensing thereof is desired, the dispensing valve is opened and the rotation of the auger section insures that highly viscous food product is physically forced to and through the valve. The auger also provides for mixing of the food product and serves to move the semi-frozen drink to and through the valve in a manner that provides for uniform dispensing thereof.
