Abstract:
A conveyor and lubricating apparatus comprising:(a) a conveyor having a conveyor surface and being provided for transporting items on the conveyor surface; and (b) a dispensing device for providing a spray pattern of a lubricant composition onto the conveyor surface, the dispensing device comprising: (i) a nozzle that generates the spray pattern when the lubricant composition is supplied to the nozzle at a pressure of greater than about 20 psig; (ii) a lubricant dispensing line that supplies the lubricant composition to the nozzle; (iii) a nozzle valve that opens and closes in response to the pressure conditions within the lubricant dispensing line to control flow of the lubricant composition to the nozzle; and (iv) a spray valve constructed to move between a first position and a second position, the first position causing pressurization of the lubricant dispensing line, and the second position providing depressurization of the lubricant dispensing line.
