Systems and methods for processing essential oils
A system for processing essential oils includes a mixing tank, three winterization vessels, three respective filtering vessels, a fine filtering vessel, a holding tank, an evaporator, an essential oil reservoir, a solvent reservoir, and a solvent filtering vessel. The evaporator can include a heat exchanger configured to heat a plate down which a mixture including the oils flows, to evaporate other components of the mixture. Fluids can be advanced through the system using a pressurized inert gas.
SYSTEM AND METHOD FOR PRODUCING A SUGAR STREAM USING MEMBRANE FILTRATION
An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production, using membrane filtration. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process) using membrane filtration, with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.

PROCESS AND SYSTEM FOR PRODUCING BIODIESEL
A method of producing biodiesel using a conduit contactor in fluid communication with a collection vessel includes: introducing a first stream including an alcohol proximate a plurality of fibers positioned within the conduit contactor and extending proximate to the collection vessel; introducing a second stream including an oil into the conduit contactor proximate to the plurality of fibers, wherein the second stream is in contact with the first stream; reacting the oil and the alcohol to for a single phase; receiving the single phase in the collection vessel; and separating biodiesel from the single phase.
REMOVAL OF UNWANTED MINERAL OIL HYDROCARBONS
Present invention relates to process for reducing MOSH and/or MOAH content from vegetable oil selected from the group consisting of palm-based oil, cocoa butter-based oil and any mixture thereof, and comprising steps of: a) Subjecting vegetable oil to short-path evaporation being performed at a pressure of below 1 mbar and under further processing conditions either: a1) at an evaporator temperature of between 210 and 240° C., and with a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment of from 35 to 105 kg/h.Math.m.sup.2, or a2) at an evaporator temperature of from 245 to 300° C., and with a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment of from 110 and 170 kg/h.Math.m.sup.2, b) Contacting the retentate vegetable oil with an adsorbent, and c) Subjecting the bleached retentate vegetable oil to a further refining step.
Method for Obtaining Gamma-Oryzanol
A method for obtaining γ-oryzanol comprises: (a) extracting an extract from a raw material containing γ-oryzanol by supercritical fluid extraction; (b) separating a pellet from the extract through solid-liquid separation; and (c) obtaining purified γ-oryzanol from the pellet.
Blown and stripped blend of soybean oil and corn stillage 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.
Winterization of fish oil
The present invention relates to a process for winterizing crude fish oil by an improved winterization process, wherein a solubilizing agent is added to the fish oil prior to the winterization. The solubilizing agent is preferably a fat-soluble edible organic compound, such as fatty acids or fatty acid mixtures. The invention further relates to compositions obtainable by the process.
METHODS OF OBTAINING LIPIDS FROM A MICROBIAL CELL COMPOSITION
The present invention is directed to a process for obtaining a lipid from a composition comprising microbial cells, the process comprising: treating the composition comprising microbial cells to a temperature of about 60° C. to about 95° C. at a pH of about 9 to about 11; separating the treated microbial cells into a light phase and a heavy phase; sequentially, in one or more cycles, raising the pH of the concentrated microbial cell composition to 10 or above, followed by lowering the pH of the concentrated microbial cell composition to a pH of less than 6 to lyse the concentrated microbial cell composition, wherein the raising and lowering of the pH also demulsifies the concentrated microbial cell composition; separating the lipid from the demulsified cell composition, and recovering the lipid.
