Abstract
An apparatus and method for lubricating conveyors and belts used in the food industry is disclosed, comprising a device including valves which are alternately opened and closed by an actuating device driven from the conveyor movement. The valves supply a lubricant which is fed to output nozzles for spraying onto the conveyors for lubricating purposes, and the valves will only feed lubricant when the conveyor is moving. Consequently, lubricant and water wastage are significantly decreased, along with excess sewage charges, and the need for a conventional electrically driven solenoid system for controlling the output of lubricant is eliminated.
