Part of the Clean-in-place (CIP) section. How P6 integrates with the plant CIP system (cycles, hookups, and acceptance testing).
Introduction
P6 does not provide a standalone CIP controller — the CIP solution is provided by the plant CIP system. This page defines how P6 integrates with that external system. P6 connects to the plant CIP supply for internal spray cleaning and uses the juice line for counter-flow backflush cleaning of the juice collection circuit. During CIP, tank isolation valving must prevent CIP fluid from entering production juice tanks.

Key equipment responsibilities and interfaces.
Colour(s)
Component
—
Plant CIP system — controls rinse/chemical cycles, pressure, temperature, and concentration; provides supply/return infrastructure.
—
P6 CIP manifolds — rigid stainless piping and flexible hose connections to plant supply.
—
Juice-line backflush integration — valves/T-junction allowing CIP solution to flow back through collectors/filter/plunger circuit.
Add figure: juice-line backflush plumbing (T-valve, check valves, drain/return path) tied to the Collection system.
Add figure: acceptance test flow (indicator test points and rinse confirmation).
Discussion
Plant-controlled CIP process
The plant CIP system typically runs the following sequence (final durations depend on plant capability and cleaning results):
Water rinse — remove bulk material.
Lye / soap solution — chemical cleaning step.
Final water rinse — remove chemical residue.
After the cycle, perform chemical indicator tests to confirm the machine is free of cleaning solution. Add an additional rinse cycle if required.
Operating requirement
Machine must be running during CIP for effective cleaning coverage.
Interfaces
Spray cleaning hookup — plant CIP supply connects to P6 spray manifolds (feeder-lid group and peel-deflector group). Flexible hoses are required to allow feeder open/close movement.
Juice circuit cleaning — CIP solution is routed through the juice line as a counter-flow/backflush to clean juice collectors, filter, and plunger circuit.
Tank isolation during CIP — required valve logic: during CIP, the normal "juice to tanks/outlet" path must be shut off so CIP fluid is routed into the collectors/filter/plunger circuit and does not flow into the production juice tanks.
Control — all cycle sequencing and parameter control is by the plant CIP system.
Questions for contractor
Define recommended hookup standard(s) (sanitary fitting type, hose spec, quick-disconnect strategy) suitable for CN plants and seasonal maintenance.
Specify required check valves/return routing/drain strategy and valve switching requirements so CIP fluid cannot contaminate production juice tanks (tank isolation during CIP) and production cannot contaminate CIP returns during cleaning.
Propose an acceptance test protocol: chemical indicators, rinse criteria, and minimum run time during CIP (tied to spray coverage and backflush effectiveness).
Interfaces and tolerances
Tolerances TBD; contractor to propose connection and mounting requirements consistent with plant CIP pressure/vibration and feeder motion.
