A specialty coffee roastery in the Pacific Northwest had been quietly losing money for years — not in a dramatic way, but in the slow, grinding way that adds up to real numbers by year-end. Their main 240kg drum roaster would drop a batch maybe once every three weeks. The grinder line would stall for ninety minutes every Tuesday because nobody had documented the chaff drawer cleaning schedule. The packaging conveyor would jam during the morning rush, sending green-bag orders out the door three hours late. None of it felt catastrophic on any given day. By the end of the year it added up to 11% downtime and over $400K in missed roasted-coffee revenue. After 7 months on OxMaint CMMS with structured preventive maintenance scheduling, the facility hit 97% equipment uptime, eliminated three of its four recurring failure modes, and the operations director finally got a full night of sleep on a Sunday — confident the Monday morning roast would actually start on time. This is the story of how that happened, and how the same framework applies to any small-to-mid scale coffee manufacturing operation on OxMaint CMMS.
What Was Actually Going Wrong on the Floor
When the operations director walked us through the plant on day one, the failures she described were not the ones a vendor brochure would call out. They were small, persistent, deeply human. The drum roaster would trip on a high-temperature interlock because the cyclone chaff collector had not been emptied since Friday. The Probat shop grinder would stall during a Sumatra dark roast because the burr clearance had drifted by half a millimeter. The packaging line valve would seize during the morning rush because the previous shift had run a vanilla-flavored batch and the residue had hardened overnight. None of these were mysteries. Every one of them had a known cause and a known fix. The problem was that nobody had a system to schedule the fix before the failure happened.

Why Coffee Equipment Fails More Than Operators Realize
Stop firefighting coffee equipment breakdowns
OxMaint runs structured PM schedules across every roaster, grinder, blender, and packaging line — catching the small failures before they take your shift offline. Live on your floor in days, not months.
Reactive Maintenance vs OxMaint Structured PM
| Operating Metric | Before OxMaint (Reactive) | After OxMaint (Structured PM) |
|---|---|---|
| Overall equipment uptime | 89% | 97% |
| Unplanned drum roaster trips per quarter | 11 events | 2 events |
| Grinder stalls per month | 4-6 events | Under 1 |
| Packaging line jam recovery time | 45-90 minutes | Under 15 minutes |
| Reactive repair share of total spend | 68% | 22% |
| Cost per critical repair | 4.8x planned baseline | 1.1x planned baseline |
| Lost revenue from downtime per year | $400K | Under $50K |
| Sunday-night operations sleep quality | Poor | Restored |
How OxMaint Handles Every Stage of Coffee Production
Coffee manufacturing equipment is more delicate and more particular than most industrial machinery. A drum roaster does not just need lubrication — it needs the right kind, applied at the right interval, by someone who knows not to over-grease the bearing housing. A grinder does not just need cleaning — it needs burr-specific clearance verification with a feeler gauge. OxMaint structures every one of these idiosyncratic tasks into work orders that any technician can execute, with photo verification and sign-off at every step. The result is institutional knowledge that survives shift changes, vacations, and the departure of your most experienced engineer. Book a demo and we will walk through how this would map onto your specific roaster and grinder makes.
Daily chaff drawer empty, weekly cyclone clean, monthly burner orifice inspection, quarterly bearing lubrication — each on its own cycle with operator ID and timestamped photo evidence.
Each grinder logs burr clearance reading, total cumulative kilograms processed, and replacement forecast. Burr changeout work orders generated automatically at 80% of OEM life expectancy.
Switching from flavored to unflavored coffee triggers a guided cleaning protocol — conveyor wipe down, valve disassembly, hopper rinse — with sign-off gate before next batch starts.
Conveyor tension, motor current draw, and seal heater temperature monitored continuously. Drift beyond tolerance triggers a work order before the line stops a production run.
Critical spares such as roaster drum chains, grinder burrs, and conveyor belts stocked based on actual consumption rate. Reorder triggers fire automatically when stock drops below safety threshold.
Every PM, every clean, every sanitation cycle time-stamped and tied to the asset. SQF Level 2 audit prep dropped from three weeks of binder building to one afternoon of report review.
What the Uptime Recovery Actually Translated To
Uptime numbers feel abstract until you translate them into bags of roasted coffee that shipped on time, customers who did not have to be apologized to, and a head roaster who finally took a Friday afternoon off without checking his phone every twenty minutes. The financial story is real and it was the number the operations director took to the founders — but the operational story is what made the deployment stick. Teams adopted the system because it made their actual work easier. Want to see how this would translate on your own production numbers? Start a free trial of OxMaint and run a baseline assessment.
