Edible oil refining process solutions

In edible oil refining unwanted components are removed from the raw oil. Every process step has its own challenges and needs specific actions and process instrumentation. The main refining process steps:

• Degumming: Remove of phosphatides from vegetable oil
• Neutralization: Remove free fatty acids from crude oils by using caustic soda or lime
• Bleaching: Remove impurities and coloring pigments
• Deodorization: Remove substances that have a negative influence on odor, taste and color

• Measure turbidity and suspended solids for quality assurance with our inline turbidity sensor OUSTF10.

The loading, unloading and storage of raw material and edible oil requires detailed information regarding quantities and volumes. It all starts with the delivery of raw material to produce edible or vegetable oil. At the end of the production the edible oil requires an optimal inventory management.

Our expertise in the field

Our radar-based measurement instruments continually and precisely monitor the fill level in the storage tanks and silos, regardless if the raw material is delivered in solid or liquid form.

• Rely on Micropilot FMR67 with 80GHz technology for highest demands in bulk solids level measurement.
• Use Micropilot FMR62 for level measurement in aggressive liquids or applications with hygiene requirements.
• Monitor your level with our cloud connected radar sensor Micropilot FWR30 in all kind of plastic and metal tanks
• Reduce inventory costs and increase productivity with complete inventory visibility thanks to our Inventory Management solution

From pressing to finished edible oil, the raw oil passes through various temperature ranges to ensure product quality. In the deodorizing step, the process temperature rises to as high as 240 °C.
