The machine is designated for cleaning of 5 pcs. smoking trolleys with dimensions 1260х1015х2260 mm at the same time and single cleaning of trolley with hung up smoking frames with dimensions 1300х1000х2140 mm. The washing process is performed with washing solution circulating in a closed cycle through special nozzle collectors. One of them is underneath and is used for cleaning the wheels and the other moves up and down, so that the whole trolley height is covered with washing solution from all sides. The washing solution itself is collected in tank behind the machine. It is fed with hot water 60°С (no heating) and equipped with stainless steel pump, which provides the solution to the nozzles. The washing agent is added manually in the tank before starting the machine (option – automatic dosing system). When returning to the tank the circulating washing solution goes through filter for catching the bigger soils.Rinsing is done through the movable (up and down) collector at two stages. The first one is rinsing with hot water, which returns to the washing tank, and the second one is rinsing with cold water, which is led directly to the discharge tank, where a vertical pump pumps it at certain height. Bringing in and positioning of the trolleys is manual. Electromechanical lock at the door prevents opening of the door during washing. The machine is chamber type and the tank, pumps and the other elements are mounted behind it. Because of that part of the construction must be dug into the floor. The machine is prepared for connection at local ventilating system, so that after every washing cycle the steam is taken out bevor the door opens. The machine control unit is Siemens, allowing the operator to set the duration of all cycles depending on the needs and contamination of the trolleys. After ending of all processes there is light and sound signal to indicate that the trolleys can be pulled out of the machine. Because of the machine dimensions it is transported in pieces and is assembled on site. The machine is made of stainless steel 1.4301 (AISI 304) and complies with the Council Directives 2006/42/ЕС and 2006/95/EC, and USDA regulations.
