Oil and Oilseed Processing II - Oklahoma State University

In the 1800s, small batch type oil extraction systems were common in Europe. The same vessel was used for both extraction and meal desolventizing. Today, extraction of specialty and high value oils and recovery of oil from spent bleaching clay are carried out in batch extractors.

Methods of Extraction for Vegetable (Carrier) Oils

Bleached: Some lipids are bleached in order to improve the color and clarity of the oil. Bleaching is generally done by passing the oil through fuller's earth or clay and then filtering the oil. Deodorized: Some lipids undergo a deodorization process in order to remove compounds that lend an unappealing or overpowering aroma to the oil.

bleach or with high phosphate content, can affect the proper function of the system. Low inert (clay) content detergents are recommended, and fabric softener sheets over liquid softeners. Bleach should be used sparingly, and at half the rate indicated on the container. Whenever possible, wash clothes and run the dishwasher only with a full load.

Interpretation of palaeoweathering- GeoScienceWorld

Extensive networks of termite burrows constructed to great depth in the bleached regolith followed the water tables down. The climate was warm and dry with a high water deficit. Groundwater silcretes formed near-horizontal lenses and pods of porcellanite and jasper in the bleached regolith. They preserve the primary fabric of the host rock.
