Smoking Faults

Treated, contaminated or unsuitable fuel and oxygen-starved combustion can generate soot, tar and bitter deposits. Heavy visible smoke is not evidence of effective or desirable smoking.

Blocked returns, poor rack spacing, dripping fat, cold surfaces and uneven flow create light and dark zones. The controller can remain stable while product positions receive different heat and smoke.

Under-smoking produces weak or uneven colour and flavour, while over-smoking can create bitterness, excessive surface deposition or a dark rim. Product diameter and surface moisture affect the response.

Direct flame, hot metal contact and condensed tar create local scorching or sticky black deposits distinct from uniform smoke colour. Corrective action should remove the mechanism rather than merely trimming the surface.

Review fuel, generator settings, chamber records, loading maps and product cross-sections. Smoking changes must not be used to compensate for missed cooking, fermentation or drying endpoints.
