Product Recovery Systems

Tuchenhagen and GEA Diessel product recovery systems (pigging systems)

The GEA Liquid Processing offers several different sanitary and hygienic product recovery systems that enable you to regain valuable products from your pipe system and thereby optimize the economic efficiency of your production plant. Residual products are expelled from the pipes and returned into the product flow by pigging. No more than a thin residual film remains in the pipe system that can easily be removed by subsequent cleaning (CIP). This technique reduces also the waste water load drastically.

The Product Recovery Systems enable you to:

• Reduce the loss of valuable products
• Reduce production down time
• Reduce consumption of rinsing water
• Reduce consumption of cleaning media
• Reduce the wastewater load

Applications:

• Product push-outs
  Product recovery systems are used whenever viscous products are expelled from pipe systems without the risk of intermixing with other media. This is especially required for high quality (and valuable) products in the food, dairy, beverage, food ingredients, pharmaceutical, biotechnology, fine chemical, and personal care (cosmetics) industries.
• Product handling
  In addition to their primary applications, product recovery systems are also used for gentle filling of process pipework systems for sensitive products and products likely to foam. This is typically done when filling vertical pipe systems downwards - essentially the pig is launched in front of the product.

Range of application in production plants:

• from product reception to pre-mix tanks
• from pre-mix tanks to mixing/process tanks
• from mixing/process tanks to storage tanks
• from storage tanks to filler lines
• from treatment lines to storage tanks/filler lines

Typical product applications:

• Thermoplastic and hygroscopic liquid pharmaceuticals
• Washing agents, cleaning agents
• Yoghurt, quark, cheese
• Fruit pulp, syrup, concentrates, puree, ketchup
• Dough, vegetable oil
• Personal care products such as shampoos, lotions, creams, toothpaste
• Internal medicines

GEA Liquid Processing product recovery systems are known for:

• their easy integration into fully automated production lines with hygienic integrity
• automatic control of the pig by detection of the pig's position outside the pipe
• safe operation due to the matrix piped closed system
• no disassembly of the pig stations for operational and cleaning purposes
• full integration into CIP and SIP systems for both new and existing plants
• fully automatic CIP / SIP-able pig stations
• fully verifiable processes. Validation and documentation is available if required
• product push-out forward or back to the source tank.
• use of different pig driving media: water, air, CO₂ or N₂
