Abstract
A system for producing droplets of a liquid, particularly for pelletizing the material. The liquid is delivered under a controlled pressure to a relatively shallow horizontal chamber, the lower wall of which is a plate having nozzles therein and the top wall of which is formed by a flexible diaphragm. There is a chamber above the flexible diaphragm which contains oil and connects through its top wall to a chamber of variable volume having a bellows side wall construction and a movable top wall. The oil also fills that chamber so that when the movable top wall is pushed downwardly, a uniform pressure is exerted on the diaphragm so as to press it downwardly and to cause a drop of the liquid to be discharged from each of the nozzle. The movable top wall is vibrated or oscillated vertically so as to produce a continuous series of droplets from each nozzle. The droplets can be solidified by falling through a heat transfer gas or by falling onto a steel belt conveyor which is cooled on its underside by a brine spray.
