UA-24579753-1
Pot, pan & utensil washers have the same washing stages as dishwashers (washing, rinsing & disinfection). Some machines are provided with additional lateral washing arms with nozzles.
One of the problems in pot washing is the removal of scorched dry food, pre-wash can be useful in this case for softening of scorched food. One of the manufacturers developed a new technique for easy removal of scorched food, which is using of small food grade plastic granules or particles (PolyOxyMethylenoxide or POM), Fig.16.6.1. These granules are mixed with water and detergent and pumped together at high pressure to flow through nozzles. Granules at this mixture impact the scorched food and remove it – see Fig.16.6.2.
Pots are then rinsed with water (without granules) which removes any remaining food and then rinsed with water at 85°C temperature for disinfection. See next example.
