Continuous processing apparatus

摘要

A continuous processing apparatus comprises a tubular assembly that has a carrying path of a constant spatial cross sectional area throughout it and a pressure control unit in the carrying path, a retainer that is provided with throttle pieces of an area slightly smaller than the spatial cross sectional area so as to create labyrinth seal at least one of the upstream and downstream locations from the pressure control unit of the tubular assembly along its carrying path, and a retainer carrying device placed in the tubular assembly for carrying the retainer.
