DEFINITION

Classification: 427/2.18

En masse rotating means employed (e.g., rotating pan, tumbling):

(under subclass 2.14) Processes in which a bed or mass of particles or unit-dosage-articles is subjected to rotating means (i.e., rotating means acts en masse as opposed to acting on a particle or unit-dosage-article individually) and in which mechanical contact between the particles or unit-dosage-articles and the rotating means occurs and contributes to movement.

(1) Note. Processes employing rotating means which create and/or maintain an emulsion or dispersion or colloid are not proper for placement here; see subclasses 2.14, 2.21, 2.22, or 2.23.
