Degumming

Crown designs and supplies a wide range of degumming processes, from water degumming to enzymatic degumming. Our MultiPure Degumming/Neutralizing system provides the ability to degum oil for storage, sale or physical refining, or to neutralize oil in chemical refining. By changing operating conditions, our degumming system can be used for multiple degumming processes. The process can be converted to enzymatic degumming by adding a few components. If needed, residual gums in the degummed oil can be reduced by either water-washing the oil or through special sorbents and filtration.

Crown processes include:

  • Water degumming
  • Acid degumming
  • Enhanced degumming
  • Enzymatic degumming
  • Cold degumming

  • Designed for optimum quality output and maximum yield, with minimum energy consumption
  • Adjustable operating conditions to match quality and process requirements
  • Flexible system design that can be used for a variety of degumming and neutralizing processes
  • Water-washing or special sorbents used to reduce the residual gums in the degummed oil


  • Atmospheric reactor with variable retention time and agitation for optimizing both degumming and neutralizing processes
  • Temperature control for each step of the process
  • High shear variable speed mixer for intensive mixing of oil and reagents
  • Conditioning reactor to ensure maximum precipitation of nonhydratable gums
