When a food plant runs 24/7 even during coating maintenance, tiny food particles floating in the air (e.g., sugar from sugar processing) in the plant can contaminate a prepared surface. How do you prevent such contamination, or identify it and remove it before applying the coating?

Preventing contamination by airborne particles ...read more Preventing contamination by airborne particles can be done by enclosing the maintenance area with canvas or plastic sheets and applying a slight atmospheric overpressure. Removing any such material can be done by brooms, pressured air sweep and ultimately vacuum cleaner. 1Identifying contamination depends on the material, but often it can be done in the first place by simple vision, if not reactives could be used but precaution should be practiced since these may contaminate as well.
