Refining Plants

A refining process is carried out following extraction of crude edible oils by means of screw presses and/or solvent extraction.
In refining, physical and chemical processes are combined to remove undesirable natural as well as environmental-related components from the crude oil. These components comprise for example phosphatides, free fatty acids, pigments (such as chlorophyll), odors and flavors (including aliphatic aldehyde and ketone), waxes as well as heavy metals, pesticides etc.
Depending on the requirements, the following basic processes are implemented:

  • Degumming for removal of phosphatides,
  • Neutralization for removal of free fatty acids,
  • Bleaching for removal of color,
  • Deodorization to distill odors and flavors as well as free fatty acids.
  • Winterization for separation of waxes.

Refined edible oils are either directly used for human nutrition or serve as feed stock for further processing for example, for mayonnaise, margarine, shortening and for the production of biodiesel. Important process steps in this context are fractionation, hardening and interesterification.

K-TEK offers customized machine solutions for any application or process to meet the individual requirements of the customers.

Different degumming processes are carried out to remove phosphatides. For efficient and economic application of this procedure  K-TEK  provides appropriate machines and equipment.
