  • Process and apparatus for recovery and recycling conveyor lubricants
    Patent number: 4897203
    Abstract: A solution of water soluble conveyor lubricant is continuously recovered from a moving conveyor through a suction bar. The lubricant is treated to reduce suspended solids, heat sterilized, the pH adjusted, and a bactericide is added. The solution is then recycled at least once to obtain about a 50%-90% recovery, and then is discharged. The process saves a significant amount of water, in addition to lubricant.
