Once in position, the operator starts the washing cycle. The initial wash stage uses a heated (65-70°C) alkaline detergent to remove the surface contamination from the mixing vessel; the typical cycle time is around 10 minutes for standard paints and inks. For harder to clean contamination, butyl, glycols or dibasic esters can be used to increase the cleaning performance of the washing media.
The wash solution is held in a 2000 litre conical tank located at the rear of the machine. When the washing cycle is taking place, the used wash solution is filtered and returned to the wash storage tank for reuse in the Rotajet vessel washing machine.
After the wash cycle, the machine automatically rinses the vessels using a water rinse; this removes any caustic residues that may be present. The rinse solution is stored in a 1500 litre conical tank at the rear of the machine. The used rinse solution is filtered and returned to the storage tank for reuse in the Rotajet vessel washing machine. PH probes can be added to the storage tank to monitor pH.
