Process-Integrated Vacuum Vessels
What Are Process-Integrated Vacuum Vessels?
A process-integrated vacuum vessel is a double-wall pressure containment system featuring vacuum insulation combined with process-specific internal components, connections, and instrumentation designed for direct integration into manufacturing or processing operations. Unlike standard storage vessels, process-integrated designs incorporate features such as internal coils, baffles, agitators, level controls, and multiple process connections that enable the vessel to function as an active component in production processes rather than passive storage. The vacuum insulation maintains precise temperature control during processing operations that require thermal stability.
Why Choose Process-Integrated Vacuum Vessels?
Process-Integrated Vacuum Vessels offer several critical advantages:
- Seamless Process Integration: Direct connection to upstream and downstream process equipment without intermediate storage
- Active Temperature Control: Vacuum insulation combined with internal heating/cooling maintains precise process temperatures
- Reduced Product Handling: Eliminates transfer steps between separate storage and process vessels
- Continuous Operation: Designed for sustained process flow rather than batch storage cycles
- Customized Functionality: Internal components tailored to specific process requirements

Frequently Asked Questions About Process-Integrated Vacuum Vessels
Can process-integrated vacuum vessels include agitation systems?
Yes, Roben Mfg designs process-integrated vacuum vessels with magnetic-drive, mechanical seal, or sanitary agitator systems. Special attention is given to maintaining vacuum jacket integrity at agitator penetrations while ensuring process hygiene requirements are met.
How are internal heating/cooling coils integrated into process-integrated vacuum vessels?
Internal coils are welded to support structures within the inner vessel, with coil connections routed through vacuum-jacketed piping penetrations. This maintains thermal efficiency while providing precise temperature control during processing operations.
Are process-integrated vacuum vessels available in sanitary designs?
Yes, we fabricate process-integrated vacuum vessels meeting 3-A Sanitary Standards, ASME BPE, and FDA requirements with electropolished surfaces, CIP/SIP capability, and sanitary clamp connections for pharmaceutical and food processing applications.
