LiquiDrainer® Conveyor Bulk Feed

Automatic, fast, economic emptying of PET bottles, cans, TetraPak® cartons, foil juice packs, etc.

The LiquiDrainer® is offered in a choice of hand-feed, bin tipper-feed or conveyor-feed models.

It automatically empties PET bottles, cans, TetraPak® cartons, foil juice packs, etc. at rates of 21,000 x 330ml/7,000 x 1 litre containers per hour.

Achieving 99% liquid removal, it enables users to divert their liquid/drinks waste to either onsite treatment or offsite processing at anaerobic digestion plants or animal feed facilities, etc.

In addition, the emptied packaging can be baled and sold on for recycling (the LiquiDrainer® is frequently supplied together with the BaleTainer® as an integrated recycling solution).

Key Features

  • Easy, safe and fast to load
  • Designed for high volumes
  • Can be integrated into your production system or as a stand-alone machine
  • Loading by conveyor
  • Made from acid resistant stainless steel
  • Low power consumption 4kw motor
  • Integral filter sump and drainage tubes
  • Optional tanks, pumps, diverter valves etc. (bespoke site solutions)

The LiquiDrainer® is a patented German machine designed to automatically empty filled PET bottles, cans, TetraPak® cartons, foil juice packs, etc. at rates of up to 21,000 units per hour.

The conveyor feed version can be fed with both individual and multi-pack products through its large infeed hopper, removing the need for costly and slow manual unpacking and emptying by hand. Conveyor feed allows for bulk loading of the hopper via the conveyor by forklift tip skips.

The machine can also be supplied as the rotor unit only (for integrated systems) or as a full system with a choice of bulk fed hoppers, pallet tippers, bin tippers, conveyors and pans.

Built completely from stainless steel to IP65 standards, the machine can be opened for easy and safe wash-down and cleaning.

How does it work?

Material is loaded into the LiquiDrainer® hopper, where it is pushed into a shredder rotor which perforates/slashes the bottles, cans etc. and squeezes out the liquid contents. The drained liquids  run through a filter box which collects any labels etc. and then drain by gravity out of the machine.

If required, these liquids can flow straight to a drain, to the site treatment plant or they can be collected in a tank with submersible pump which feeds them into IBC containers or a silo etc. For sites processing multiple products where different liquids need to be treated separately we can also supply a diverter system so that, for example, milk goes to a silo, fizzy drinks go to an IBC and water goes to drain.

The emptied packaging is forced through an upward sloping chute which can deliver it into bins, bags, or a baler for onward processing.
