Loading procedure
- Wheel trolleys to the loading dock; load shelled halves onto trays at 10 kg/m² (single layer, equator up).
- Wheel trolleys into the room — 16 trolleys in 2-abreast × 4 along configuration.
- Confirm door closed and interlocked; start batch from HMI.
Quality checks
| Check | Method | Target |
|---|---|---|
| Final moisture content | Halve 10 random halves, oven 105°C / 24 h | 5.0 ± 0.5% wb |
| Moisture uniformity across batch | Sample top/mid/bottom tray of each channel | σ < 0.4% |
| Colour | Visual vs reference | White to pale cream; no brown scorch |
| Condensate mass balance | Tank volume vs final MC | Within ±5% |
Maintenance schedule
| Frequency | Task |
|---|---|
| Each batch | Inspect and clean tray mesh; check condensate tank |
| Weekly | Clean evaporator/condenser coils; verify sensor calibration |
| Monthly | Inspect fan belts/bearings (if any); check refrigerant sight-glass |
| Annually | Refrigerant charge check; compressor oil sample; pressure-test safety circuit |
