ABSTRACT:
Apparatus for pelletizing liquid and viscous products. A body of the liquid or viscous material is enclosed within a chamber having discharge orifices or nozzles at the bottom of the body of liquid. There is a body of gas above the liquid which is subjected alternately to increased and decreased gas pressures so that the pressure on the body of liquid is first above and then below atmospheric pressure. That causes the product to be discharged from the orifices in droplets. The droplets are then solidified to form pellets. A predetermined liquid level is maintained within the chamber. The changes in gas pressure are produced by operating a valve which connects the body of gas in the chamber alternately to a suction line and supply line for gas under pressure.
