Refrigerated solvent is fed through a cooling jacket around an essential element extraction vessel. After circulating through the cooling jacket, the solvent is re-chilled and at least some of the solvent is passed into the extraction vessel, in which essential elements dissolve into the solvent. Downstream of the extraction vessel, after adsorbent media treatment, the extracted oil and solvent mixture is filtered, in a chilled state, through one or more filtration units. A filtration unit may be a system of vertically oriented filters of decreasing pore size sealed and insulated from the atmosphere. Pressurized gas is used to force the oil and solvent through the filters. Each filter stage has a removable lid, which provides convenient access for replacing the filter cartridge without disturbing the thermally insulated sidewalls of the filter stage.

The present invention relates to a process for preparing a refined vegetable oil. It relates to a process for reducing the content of free chloropropanols and chloropropanol fatty acid esters in a vegetable oil, and it is comprising the following steps in order: a) refining a vegetable oil, wherein the refining is comprising at least a deodorization step at a temperature below 230 C., and subjecting the refined vegetable oil to a short path evaporation, and collecting a vegetable oil having a content of free chloropropanols and chloropropanol fatty acid esters of not more than 500 ppb and a color expressed as its red component equal or below 3.0.

The present invention relates to a process for increasing the oxidative stability of short path evaporated oils. The process comprises the step of adding to the short-path evaporated-treated oil at least one anti-oxidant while the short-path evaporated-treated oil has a peroxide value of below or equal to 1.5 milli-equivalent peroxide/kg. The at least one anti-oxidant is preferably added at a temperature above the melting point of the short-path evaporated-treated oil.

A method for producing a high viscosity, low volatiles blown stripped oil blend is provided. The method may include the steps of: (i) obtaining an oil blend of corn stillage oil and soybean oil having a weight ratio of corn stillage oil to soybean oil of from about 1:2 to 3:1; (ii) heating the oil blend to at least 90 C.; (iii) passing air through the heated oil blend to produce a blown oil having a viscosity of at least 50 cSt at 40 C.; and (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram.
