Abstract: A tacky substance such as a chewing gum base is formed into a compact body. The tacky substance is first comminuted within a bed consisting of a powdered solid, such as a bulking agent, turbulently suspended within a gaseous medium at room temperature. The tacky substance is subjected to repeated mechanical impact within the powdered solid to pulverize it into particles which are then immediately coated by the powdered solid in order to prevent cohesion between the particles. The coated particles are classified to identify those suitable for tableting and the suitable particles are then fed into a tablet press to form a compact body.

Abstract: In the manufacture of chewing grum, the viscosity of a chewing gum base is first reduced by heating. Thereafter, a major portion of a bulking agent, such as a carbohydrate, is added to the gum base while homogeneously mixing the ingredients. The mixture is cooled in order to increase its viscosity and to form granules thereof. The balance of the bulking agent is then added, preferably in increments, to form layers around the granules. The overall effect of the resultant chewing gum product is an improved initial taste impact due to the superficially positioned, typically sweet, bulking agent and a subsequent, long-lasting taste development due to the internal mixture of the bulking agent with the base.
