An ethanol production process and system for recovering high value oil products. The invention includes adding a heated lipid (oil) stream to a thin stillage stream to break the water/oil emulsion and free bound oil then recovering the oil. The process uses oil as the heat transfer mechanism to increase both the volume and quality of the oil recovered.

Systems and methods for improved rendering of animal products may utilize a multi-step process including at least a heating step through use of a steam-jacketed tube system and a pressing step to squeeze out the oils. Grinding and pre-breaking may first be used to break the fat/whole animal into pieces. The ground material may then be transported and heated in one or more steam-jacketed tubes to create a slurry. A press may then be employed to press out the oil and water from the slurry. Residual solids may be removed from the oil and water through a decanting step. Water and extremely fine materials may then be removed from the oil through a centrifuge step, and the oil may be transferred to one or more storage tanks. Following the pressing step, the protein that remains may be subjected to high pressure to squeeze out any residual fat and then may be transferred to a hammer mill to prepare into a powdered protein or other desired protein material that may be stored for later use.

A method for the separation of fat from animal by-products includes a supply step a) of providing a feed stock of animal by-products, a treatment step b) of heating the feed stock, a comminution step c) of comminuting the heated feed stock, where the feed stock is reduced in size to obtain fragments with a size of 10 mm or less, and where a three-phase system, including a fat phase, an aqueous protein phase and a solid phase, is obtained, and a separation step d) of separating the fat phase from the three-phase system obtained in comminution step c).

A fat-containing composition obtained by converting insects or worms into nutrient streams, such as a fat-containing, an aqueous protein-containing and a solid-containing fraction, including (a) squashing insects or worms thereby obtaining a pulp, the insects or worms reduced in size, (b) heating the pulp to 70-100 C., and (c) subjecting the heated pulp to a physical separation step with the proviso that the method does not contain enzymatic treatment of the pulp. The fat-containing fraction contains at least 80 wt. % insect or worm fat with at least 40 wt. % saturated fats. The aqueous protein fraction can be dried to obtain dried protein material, which contains at least 50 wt. % insect or worm protein-derived matter and at most 25 wt. % insect or worm fat based on dry weight. The protein has a pepsin digestibility of at least 50%. The resulting nutrient streams can be used in food, petfood, feed and pharmaceutical industry.
