This idea is a way to disinfect the surfaces of goods purchased from the bigger supermarkets by passing them through a tunnel. The mechanism of operation of this tunnel is to spray the shopping baskets or trollies with a disinfecting liquid while the goods are placed on the moving conveyor belt and passing through the tunnel. The powerful nozzles that turn the 70% alcohol sanitizing liquid into fine droplets, spray all the items for one minute in three stages. The tunnel is equipped with motion sensors, which activate the nozzles and the belt only when there are items on conveyor belt to save power and the sanitizing liquid.
