Self-Cleaning Filtration of Honey

Self Cleaning Filtration of honey


The objective was to remove some particulate matter in honey, but only specifically larger than 100 microns. The main contaminant is bees wax, and naturally occurring pollen has to be retained, which is around 50 microns.



Previous systems fell short of the requirement. Critical product characteristics:

  • Filtration tolerance
  • Viscosity
  • Temperature
  • Effect of filtration on product
  • Particulate character

The method of operation of Oxford Filtration DN50 Inverted Self Cleaner Filter is essential to the success of the filter. If the filtration level is too fine, the product doesn’t meet standards.

If the filtration level is too high, the product crystallises on the shelf in its bottle. The design of the filter element was determined during initial trials, a special perf element with special blades performed better than the standard element.

It is critical that the filtration is within a narrow temperature range as the viscosity will adversely affect the performance.

The unit is insulated and trace heated, flow is in a downward direction as the wax tends to float. The wax is removed from the vent valve, the element is rotated continuously at a low RPM, which enables a fixed system pressure to be maintained.

As a premium British product, consistency is crucial, and as competing against lower cost imported products, it is important the manufacturing costs are kept to an optimum. The customer has been very inventive, making modifications to the filter to enable the process to run with the minimum of disruption.
