FG Backflushing filters for honey filtration

Apart from the work done by the bees themselves, the collection and extraction of honey is a relatively simple process in which small and large producers worldwide use very similar techniques. This is generally done with a centrifuge followed by a filtration process to remove pollen residue, bee body parts such as legs and wings, and solid wax particles from honeycomb residue.

Challenge

The pollen contained in honey must be preserved as an essential ingredient. The processing temperature is strictly limited by law during the entire processing so that a correspondingly high viscosity must be taken into account. The following points represent an additional challenge and must be considered accordingly:

  • Low flushing quantities
  • Sharped trend limit
  • Avoidance of cake formation on the filter element
  • Treatment and recirculation of flushing quantities

Technical data

Solution statement

  • In order to minimize the flushing quantities, the flushing nozzle principle is designed in a special form with regard to the diameter / height ratio of the backflushing valve and filter element
  • This also accomodates the high viscosity of the medium; the design of the filter housing with the corresponding flow control optimises the overall concept from a process engineering point of view
  • In cooperation with the customer, a filter element was developed which reliably filters out the foreign particles while at the same time allowing the pollen fraction to remain in the product

Customer value

  • Proven and optimized backflush technology
  • Optional secondary treatment removes the residual honey from the flushing volume and thus reduces product losses to an absolute minimum
  • Complete product recovery through flush vo.lume preparation
  • Reliable discharge of foreign and interfering particles
  • High application competence and experience
  • Customized solutions
