Abstract
An apparatus for a continuous encapsulation process is provided. The apparatus is a vibrating tubing used alone, in series, or in combination with an encapsulation apparatus, which is used alone or in series. The vibrating tubing is a flat coil, a standing spiral, or a flume. The encapsulation apparatus includes a winding having coils disposed in an aqueous gelling solution. The winding is rotatable about its longitudinal center axis. The winding has adjacently spaced coils forming a plurality of chambers. Objects to be encapsulated are added to the apparatus such that when the winding is rotated, the chambers transport a volume of objects through the length winding in the aqueous gelling solution in a predetermined time.
