Operation & Unit-Procedure Templates

Pre-built compositions of phase templates for common pharma sequences. Operations are ordered sequences of phases, and unit-procedure templates compose operations into a reusable procedure skeleton that a master recipe can bind to a specific unit.

Unit-Procedure Templates

The reference plant ships one CIP unit procedure template per unit type, all following the same structural pattern. Each is referenced directly from its corresponding CIP master recipe, with the pressure/leak-test step retained at the master-recipe level as a separate phase call.

Template Unit Purpose
cip-vessel-cleaning mix-tank-1 Mix-tank CIP — pre-rinse, hot wash, rinses, conductivity check, blowdown.
reactor-cip-cycle reactor-1 Reactor CIP — pre-rinse, caustic wash, intermediate rinse, conditional acid wash, final rinse with pH endpoint.
fd-cip-cycle filter-dryer-1 Filter-dryer CIP — through-plate pre-rinse, hot wash, post-rinse. Drying and vent remain at the master-recipe level.

Operation Templates

The generic mix-tank CIP operations use generic CIP phases (cip-fill, cip-agitate, cip-heat-and-hold, cip-drain, cip-conductivity-check, cip-pressurize, etc.) that bind to the mix-tank's inlet_valve / outlet_valve / agitator roles. The reactor and filter-dryer have different role topologies (the reactor uses wfi_valve + outlet_valve + jacket_controller, and the filter-dryer uses wash_valve + filtrate_valve + vacuum_controller) so they get unit-specific phase templates, and the operation templates below are thin wrappers over those unit-specific phases.

Template Unit scope Purpose
cip-rinse-op generic (mix-tank) CIP rinse operation — fill with WFI, agitate, drain.
cip-hot-wash-op generic (mix-tank) CIP hot chemical wash — fill chemical, heat, agitate, drain.
cip-conductivity-rinse-op generic (mix-tank) Final rinse with conductivity endpoint verification.
cip-blowdown-op generic (mix-tank) N₂ blowdown — pressurize headspace and drain residuals.
reactor-cip-rinse-op reactor Reactor-specific WFI rinse — wraps the reactor-cip-rinse phase.
reactor-cip-hot-wash-op reactor Reactor-specific hot wash with optional skip — wraps the reactor-cip-hot-wash phase.
reactor-cip-ph-rinse-op reactor Reactor-specific final pH rinse — wraps the reactor-cip-ph-rinse phase.
fd-cip-rinse-op filter-dryer Through-plate rinse via vacuum — wraps the fd-cip-rinse phase.
fd-cip-hot-wash-op filter-dryer Through-plate hot wash with optional skip — wraps the fd-cip-hot-wash phase.
