Title: Bottle-washing machine - maintains low alkaline concentration of final bath by diverting part of rinsing water from upstream spray nozzles for alkaline bath
Inventor: FREY EGON
IPC: B08B9/30
Filed: 1992-07-29
Abstract: The bottle-washing machine has a series of treatment zones through which the bottles are carried on an endless conveyor.
