Abstract
Abstract Process of making sugar and products containing predominantly sugar wherein sugar syrups are evaporated and then beaten to make a fondant-like material by a process wherein the crystallized product is screened to produce an intermediate, salable, fraction of the desired particle size, a coarse material (scalpings) and a fine material. The fine material is pelletized and combined with the coarse material and passed through a comminutor and the comminuted product is returned to the screening stage. This produces a product having a particle size distribution within a narrow range which is free flowing and in practically 100 percent yield.
