Abstract
Provided is a method for cooling wax after coextrusion to create wax capsules. The method includes immersing a concentric nozzle of a coextruder in a container of heated alcohol. The container of heated alcohol sits in a water-ice bath to create a temperature gradient. A core material having a wax coating is extruded through a concentric nozzle to form a capsule. The capsule enters the container of hot alcohol where the wax coating is solidified. In an embodiment, the method is a continuous method including a capsule and solvent transfer system.
