摘要： An apparatus for intermittently dispensing fragile particulate material such as sesame seeds onto the upper surface of bakery products. Difficulty has been encountered in dispensing fragile particulate material because of the grinding or milling which results from movement of members employed for dispensing metered quantities of the material. The present system prevents grinding of the material by providing blocking collars on a mandrel. The collars have a diameter greater than the diameter of the mandrel so that the outer surface of the mandrel is spaced away from the inner surface of a hollow dispensing tube. The space prevents grinding of the material when the mandrel is rotated. The apparatus comprises a hopper (40) having a hollow tube (46) at its bottom end. An outlet passage (50) also extends through the wall of dispensing tube (46). A mandrel (60) has blocking collars (62) formed at spaced locations along the length thereof and is rotatably supported in the bore (48) of dispensing tube (46). Spline teeth (65) are formed on mandrel (60) between blocking collars (62) for forming dispensing sections in bore (48). The major diameter of the spline teeth on the mandrel (60) is less than the outside diameter of the blocking collars (62) to provide an arcuate annular dispensing passage between the interval of the dispensing tube (46) and the major diameter of the spline teeth in a range of 1-1/2 to 2 times the diameter of particles of material being dispensed.
