Map the real circuit
Trace supply, product, return and drain routes through every valve state. Include filler manifolds, tank lids, sample valves, pump seals and short unused branches. Identify what is cleaned in place and what must be opened.
Choose the worst residue for the trial
Oil films, concentrated paste, seeds and thickener can remain in different locations. Persistent chili flavour is a separate product-changeover concern. The plant should select a verification method appropriate to its products rather than treating a clear rinse as complete evidence.
Make access part of the purchase
Ask to see removal of screens and wear parts, safe access to agitators and the path for draining low points. Agree cleaning acceptance criteria and labour requirements before comparing automated cycle descriptions. No universal chemical concentration or duration is specified here.
