A dispenser for distributing food seasoning and other cohesive solids includes a rotating auger enclosed by a tube which is fed via a hopper. The auger is divided into two sections, each with a different pitch. In a first metering section, the pitch is narrow to facilitate accurate metering of the seasoning. This is followed by a distribution section of higher pitch which reduces the bulk density of the seasoning so that it passes easily through a series of apertures in the tube. A sleeve is slidably secured to the tube and has a series of apertures registerable with the apertures in the tube. By adjusting the degree of register, the seasoning can be distributed evenly along the entire length of the distribution section. The tube contains a second set of apertures located about 180 DEG from the first set, and which are used for distribution of non-cohesive, small particle size material, such as salt. The dispenser may be mounted in a rotating drum and used for seasoning snack food, such as potato chips and the like.
