Introduced: September 1968

Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: CRUSHING, PULVERISING, OR DISINTEGRATING; PREPARATORY TREATMENT OF GRAIN FOR MILLING
Subclass:: PREPARING GRAIN FOR MILLING; REFINING GRANULAR FRUIT TO COMMERCIAL PRODUCTS BY WORKING THE SURFACE

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.
