Machine configuration
Approve a rinsing station against your actual bottle and agreed rinse process. Ask the supplier to identify what enters the bottle, how it is delivered and drained, and how the proposed cycle will be checked at the required output. A photograph of a rinser does not establish cleaning or microbiological performance.
Give bidders the bottle material, neck opening, geometry, incoming condition and intended rinse medium. Have the process owner specify the required water or air quality; the equipment supplier should return the connection conditions and cycle assumptions.
Ask how the bottle is gripped, inverted, presented to the nozzle and returned to the transfer point. Different necks or bottle weights may need different handling parts. Include the smallest opening and the least stable approved bottle in the review.
Request the supplier's stated contact and drainage conditions at the reference speed, plus the response to absent bottles or loss of rinse supply. More stations alone do not explain the available cycle or prove the result.
Use the approved material, observe nozzle alignment and residual liquid, and record bottle damage, supply interruptions and restart behavior. Process or microbiological validation belongs to a separately agreed quality protocol; a mechanical FAT cannot substitute for it.
Do not infer sterilization from a rinse stage. Ask the responsible quality team to define the required hygienic outcome and the validation evidence for the proposed process.
Only after the supplier reviews all bottle drawings and required change parts. Nominal volume alone does not define gripping, nozzle access or drainage.
Send bottle drawings and samples, incoming bottle condition, target output, proposed rinse medium and available supply/drain connections.
