    FAQ

    The Vapor phase drying process is carried out in the autoclave with the built-in cascade evaporator using advance vapor phase drying process sequence i.e. heating up phase, intermediate pressure reduction phases, pressure reduction phase, fine vacuum phase and aeration phase. The plant is offered with a cascade evaporator system.
