A01J

MANUFACTURE OF DAIRY PRODUCTS

Introduced: September 1968

Description

A01J encompasses methods, apparatus, and systems for processing milk and producing dairy products including cheese, butter, yogurt, and other fermented or processed milk-based foods. The classification covers milk handling equipment such as separators, pasteurizers, homogenizers, and churns, as well as techniques for curd formation, fermentation, and product finishing. This subclass excludes general food processing machinery (covered under A23) and focuses specifically on dairy-specific manufacturing processes and equipment used from raw milk collection through final product packaging.

IPC and CPC are identically structured here. All 15 subcodes exist in both systems.

4 shared codes have differing titles between IPC and CPC.
