B02B PREPARING GRAIN FOR MILLING; REFINING GRANULAR FRUIT TO COMMERCIAL PRODUCTS BY WORKING THE SURFACE (making dough from cereals directly A21C; preservation or sterilisation of cereals A23B; cleaning fruit A23N; preparation of malt C12C)
Introduced: September 1968
Description
B02B encompasses machinery and processes for conditioning grain before milling operations, including cleaning, sorting, moistening, and tempering to optimize milling quality and efficiency. The subclass also covers surface refinement techniques for granular fruits—such as polishing, grading, or abrading—to produce commercial-grade products. These preparatory operations improve the functional properties of raw materials, enhance product uniformity, and facilitate subsequent processing stages. Related grain milling machinery itself falls under B02C, while general crushing and pulverizing operations are classified separately in the B02 hierarchy.
