Centrifuge SPO, Supplier Evaluation, and Lessons-Learned Transfer

SMART targets: supplier evaluation by June 30, 2025; AFE approval by September 30, 2025; specifications, procurement and installation planning by December 15, 2025; SPO due February 28, 2026.

Proposed using centrifuge supplier and centrifuge supplier installations as future long-term comparisons of cost, service and performance, subject to equipment retention/return and AFE decisions. The message requested a decision; it does not establish both installations or later performance.

Distinguished high-clarity wine duty from vinegar polishing and membrane recirculation. One comparison reported about 4–8 NTU wine at 10–12 GPM from 700–800 NTU rice/cider feed on a system nominally quoted at 30 GPM; another reported a similar operating range. Other comparison notes used 0–10 NTU as an ideal wine range and discussed intolerance above 20 NTU. Apple/rice streams represented about 80% of the referenced production mix. These product and fermentation differences guided cross-site trial interpretation and supplier sizing.

Investigated an approximately 10 GPM product loss through an air-operated valve and distinguished meter sensitivity from PLC interpretation of the loss as normal outfeed. Compared adding alarms/interlocks, preventive inspection, limit/proximity feedback, an integrated-position valve and a fail-closed valve with revised logic. Requested supplier feasibility and programming pricing before treating the protection as implemented.

Used plant-reported filtration costs to compare alternatives:1500 USD was described as typical for a 6000-gallon vinegar batch, while some batches had cost 6000 USD. The notes contrasted batch duration and ceramic operation across 6000- and 60000-gallon runs; they did not establish a new annual savings amount.

Surveyed which plants use DE/media treatment for wine, DE treatment for vinegar, cartridge filtration for apple-cider vinegar and centrifuges for each duty. Distinguished upstream wine clarification from downstream vinegar polishing and treated color/carbon removal separately when evaluating a common separation platform.

Tracked supplier and plant actions for Ethernet access, OEM assistance with NTU scaling/recalibration, critical-alarm shutdown logic and service quotations. Assigned follow-up did not itself establish closure of the control changes.

Evaluated settling followed by repeat centrifugation and automatic recirculation for improved clarity, foam control and product recovery. Compared hermetic design and oxygen-pickup concerns while keeping recirculation proposals separate from demonstrated production improvements.

Collected feedback on separation tuning, routine attention to sound and process condition, satisfaction with the existing machine and willingness to buy it again. Used the observations to compare operating practices and support needs without attributing cross-site reliability differences to a single cause.

Compared reports from separate facilities of clogged solids pumps, dirty level sensors, overheated plastic auger housings and damaged motors against operating practices. The review covered dry-running stator wear, long-sweep piping, sensor cleaning, water-filter care, wash cycles and a watchdog that would stop the machine on critical conditions. One report described annual filter replacement, monthly sensor wiping, six-month housing replacement, caustic cleaning and freshwater rinses. Divergent views on unattended operation and service responsibility prompted explicit safe-standby requirements; no universal operating procedure was adopted from one site. A separate report described 2% caustic cleaning without exceeding three production batches between caustic cycles. A 60–180 second watchdog interval was raised for evaluation without a finalized setting.

Evaluated common equipment platforms for shared spare parts, operator cross-training and more consistent formula transfer between plants, while recognizing that common obsolete equipment can create a simultaneous multi-site support problem. Labeler spare-part availability across four bottling lines illustrated that tradeoff.

Compared solids collection and drain disposal against each plant’s wastewater permissions. The comparison facility’s handling allowance did not establish permission at other plants, so waste routing and pumpable-versus-collected solids were included in trial and installation planning.
