Abstract
An apparatus to batch or continuously form solid polymer particles, the apparatus comprising the following components: A) at least one pastillation unit comprising a pastillation head, said unit used to form discrete molten polymer particles from a polymer melt; B) a moving belt to receive and transfer the discrete molten polymer particles from the pastillation head; C) a means to transfer water onto the moving belt, such that the water comes into contact with the discrete molten polymer particles on the moving belt to form the solid polymer particles; and wherein the water of component C is sprayed onto the discrete molten polymer particles, such that the ratio of 'the rate of water spray' to “the discharge rate” is ≥3.0; and wherein the belt residence time is ≤50 seconds.
