B01F MIXING, e.g. DISSOLVING, EMULSIFYING OR DISPERSING (mixing paints B44D3/06)
Introduced: September 1968
Description
B01F covers apparatus and methods for combining, blending, or dispersing materials through mechanical or physical means, including dissolution of solids in liquids, emulsification of immiscible liquids, and dispersion of solids or gases in fluids. This classification encompasses mixers, stirrers, agitators, and related equipment used across chemical, pharmaceutical, food, and industrial processes. It includes both static and dynamic mixing devices, batch and continuous operation systems, and covers the physical interactions that achieve homogeneous or stable dispersed phases without chemical reaction as the primary purpose.
