Working Method

Single-ended machine using the combined soak and spray method. Bottle cells mounted on an endless chain pass through the following zones: 1. Pre-sprinkling, discharge of remains, pre-soaking, flushing pre-soaking, pre-spraying II, caustic pre-spraying, caustic soaking I, caustic soaking in two positions to remove labels,  hot caustic spraying with high volume and low pressure, caustic soaking II, caustic flushing in two positions for second label removal, with high volume and low pressure.

Cool down area consisting of:
caustic-I spraying, caustic-II spraying, warm-water-I spraying, warm-water-I spraying, cold-water spraying and fresh-water spraying.

Extensive drip zones result in low alkalinity in the water spray zones. The cascade principle where the flow of water inside the machine is opposite to the transport direction of the bottles results in an automatic regulation of temperature in all treatment zones.
