This Guide reviews the unit operations typically employed in continuous manufacturing and aims to establish a set of minimum equipment requirements for each system to function as part of an integrated process train. While most of the units are well-understood and used in batch manufacturing, the Guide considers the changes in physical and automation requirements that will allow each unit to work in concert as part of a successful continuous manufacturing platform. Operations unique to CM, loss-in-weight feeding and continuous blending, are discussed, including how these systems affect upstream and downstream operations.
