Pig cleaning technology


Functional description and benefits:


Pig cleaning technology daxPur will be used mainly for product release (almost 100% use of product possible) or for a clear separation of sequenced product batches in pipelines. On the other hand pig cleaning technology daxPur will be also used for cleaning of the pipeline (CIP-cleaning possible) after product flow. The operation-process should not be interrupted normally.

The pig completely fills the line cross-section and moves either with the product flow through the pipeline or is pressed through it via extra used pressure (created with water or compressed air).


For using the pig cleaning technology not only pigs, also charging and extraction stations are required. The pig will be inserted at the charging station and applied with pressure. Having cleaned the relevant section, the pig can be ejected at a special extraction station. The relevant pigable valves are able to open the cross-section completely, like e.g. ball valves and shut-off valves.


Field of application of the pig cleaning technology daxPur:

  • Pre-dough / sponge
  • Sour dough
  • Liquid yeast
  • Oil, fats
  • Confectionery, cream fillings, chocolate
  • Beverage industry, syrup
  • Food industry (e.g. ketchup, sauces), meat industry
  • Raw materials, e.g. concentrates
  • Paper industry
  • Color industry
  • Liquid binding agent, starch glue

special advantages

  • Enables the full product discharge from a pipeline
  • Cost savings thanks to quick fitting times during product change
  • Prevention of cross-contaminations, no mixed phases
  • Mechanical pre-cleaning of the pipeline
  • 90% saving on rinsing water thanks to low pollution load
  • Lower burden on wastewater treatment plants / sewage management
