The stainless-steel buggies are loaded by means of a “fork” gripper with an automatic drive. Buggies are washed by means of a number of high-pressure washing nozzles, through which a cleaning solution is supplied. The solution is prepared in a tank, where running water from the water supply system enters through a pipeline and pushed by a water pump. Heating elements maintain the temperature of the water in the tank with a cleaning solution which is run by the pump to the washing head with the nozzles. The used washing solution flows back into the tank, passing through the filter. The rinsing system includes a rinsing nozzle and a hydraulic gun for manual rinsing of the outer surfaces of the container. A water outlet is used to drain the cleaning solution from the washing tank.
