Start outside the machine
Inspect collection bins, floor drains, spilled waste, unwashed trolleys and old material around the loading area. A clean machine can still sit inside a dirty waste room that produces the complaint.
Check segregation and feed condition
Plastic bags can trap wet residue, excess liquid can alter the process environment and unsuitable feedstocks can behave differently. Confirm that the incoming stream matches the operating instructions.
Check whether the machine is being overloaded
Routine loads above the published capacity can reduce operating margin and affect mixing, heating and handling. Compare actual weighed loading with the rated daily capacity.
Ventilation and curing matter
Odour may come from discharged material or curing bins rather than from the sealed processing vessel. Separate the source before changing machine settings.
Escalate recurring odour as a process issue
If housekeeping and feed conditions are correct but odour persists, record the load, waste type, moisture observations, alarms/settings and timing, then contact the manufacturer or competent service team. Avoid random changes to control parameters.
Diagnose the source before changing machine settings
Odour complaints are easier to solve when the source is isolated. Check collection bins and drains, then the loading area, then the processing cycle, and finally the curing zone. Note when the smell appears and what changed that day—load, liquids, contamination, downtime or housekeeping. This sequence avoids random parameter changes that may hide the real cause.
- Locate the strongest odour point.
- Compare the complaint with that day’s measured load.
- Check spills, drains, bins and curing separately.
- Escalate persistent process issues with a simple operating log.
Smell is a diagnostic clue; first identify where and when it starts.
