Patent number: 7579492Abstract: Soybean oil is extracted by a two-stage process in which up to 85%, preferably from about 60 to about 75%, of the soybean oil in soybeans is extracted by mechanical or solvent extraction to produce first extracted oil and oil-containing meal. The first extracted oil is then refined by caustic or physical refining. Substantially all of the oil remaining in the meal is extracted by solvent extraction to produce second extracted oil and substantially oil-free meal. The second extracted oil may be transesterified for use in biodiesel fuel.Type: GrantFiled: September 30, 2003Date of Patent: August 25, 2009Assignee: Carolina Soy Products LLCInventor: Jerry E Tysinger

Patent number: 7544820Abstract: A solvent extraction free, caustic refining free, process for producing refined vegetable oils, including soybean oil, cottonseed oil, rapeseed oil, and canola oil, is described in which the vegetable seeds, after cleaning, cracking and dehulling, are heated and mechanically pressed to separate oil. Free fatty acids are then removed from the pressed oil through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The resultant oil exhibits a significantly greater frylife than non-hydrogenated vegetable oil produced by solvent extraction and caustic refining.Type: GrantFiled: June 29, 2006Date of Patent: June 9, 2009Assignee: Carolina Soy Products LLCInventors: Jerry E. Tysinger, Robert B. Dawson, Jerry F. Richmond

Patent number: 7314944Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans is described in which soybeans, after cleaning, cracking and dehulling, are crushed in less than 60 seconds while heating the soybeans to a frictionally generated temperature of from about 300° F. to about 370° F. Free fatty acids are then removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The resultant oil exhibits a significantly greater frylife that non-hydrogenated soybean oil produced by solvent extraction and caustic refining.Type: GrantFiled: March 15, 2005Date of Patent: January 1, 2008Assignee: Carolina Soy Products LLCInventors: Jerry E. Tysinger, Jerry F. Richmond, Robert B. Dawson

Publication number: 20070208187Abstract: Soybean oil with an improved frylife is produced from soybeans having less than 3% by weight C18:3 acids based on the total content of free fatty acids by heating the soybeans at a time and temperature sufficient to enable extraction of oil from the soybeans; mechanically pressing the soybeans to separate the oil; and heating the oil at a temperature of up to about 500° F. under a vacuum to remove free fatty acids from the soybean oil.Type: ApplicationFiled: March 1, 2007Publication date: September 6, 2007Inventor: Jerry E. Tysinger

Patent number: 7112688Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans includes the steps of heating cleaned, cracked and dehulled soybeans at a temperature of from 220° F. to 600° F. for from 45 to 60 minutes; mechanically pressing the heated soybeans to separate soybean oil; and heating the extracted oil at a temperature of from about 350° F. to about 500° F. under a vacuum to remove free fatty acids from the soybean oil.Type: GrantFiled: August 11, 2005Date of Patent: September 26, 2006Assignee: Carolina Soy Products, LLCInventors: Jerry E.

Patent number: 6511690Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans is described in which soybeans, after cleaning, cracking and dehulling, are extruded through a screw extruder in less than 30 seconds while heating the soybeans to a frictionally generated temperature of from about 300° F. to about 370° F. These conditions produce soybean oil that is low in nonhydratable phospholipids. As a result, free fatty acids can be removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The process also includes conventional degumming and bleaching of the soybean oil after extraction and before physical refining.Type: GrantFiled: February 1, 2001Date of Patent: January 28, 2003Assignee: Carolina Soy Products, Inc.Inventors: Jerry E.
