The cleaning process in can manufacturing involves several critical stages: pre-wash, wash, and treatment, which utilize heated water and specific chemicals to ensure effective cleaning.

In these stages, a boiler heats the water, while heat exchangers equipped with mixing valves stabilize the temperature within the tanks. This precise temperature control is essential for optimal cleaning performance.

The conveyor system features hold down conveyors that securely clamp the cans, preventing them from tipping during the high-pressure washing phases. An open mesh design minimizes obstruction of overhead spray patterns, enhancing the efficiency of the cleaning process.

During the first two washer stages, cans are sprayed with cleaning chemicals. Residual oil and lubricants from the cans drain into recirculation tanks, where they can be managed effectively. Coalescers play a vital role in this stage, separating oil from cleaning chemicals to enhance cleaning efficacy.

After each washing stage, a blow-off station and a belt wiper are employed to remove excess liquid. Positioned above the cans, the blow-off station uses a fan to minimize liquid carryover from the domes (the concave bottoms of the cans). The liquid collected is then drained and returned to the preceding stage.


This structure ensures a thorough cleaning process, essential for maintaining the quality of the cans.
