Patent number: 6440475Abstract: A grain moisture measuring apparatus and method for measuring the moisture content of the grain as the grain moves through a grain conditioning system in which moisture is applied to the grain at a first location. The grain moisture measuring apparatus includes a sample extraction mechanism located at a point downstream from the first location where moisture is applied to the grain. The sample extraction mechanism extracts a sample of grain from the grain moving through the grain conditioning system. A grinding mechanism is connected to the sample extraction mechanism with the grain sample being transferred to the grinding mechanism which then grinds the sample to physically alter the sample. The apparatus further includes a moisture sensor positioned adjacent the grinding mechanism wherein the sample of grain is transferred to a location adjacent the moisture sensor after the grain sample is ground so that the moisture sensor measures the moisture content of the grain sample.Type: GrantFiled: September 14, 1999Date of Patent: August 27, 2002Assignee: SarTec CorporationInventors: Larry McNeff, Steve Rupp, Matt Wendorf, Joel Claflin, Clayton McNeff, Pete Greuel, Lowell Sedler

Patent number: 5347468Abstract: A method and apparatus for controlling the addition of a liquid to a continuous flow of material. An algorithm is described for controlling the hydration process within a computerized grain delivery system. The grain delivery system operates by adding moisture to grain moving through the system, testing the moisture level of the hydrated grain and controlling the rate of flow of the wetting agent as a function of the wet grain moisture reading. In addition, a method is described for determining the relationship between dry grain moisture level, hydration level and the expected wet grain moisture level reading. Finally, a communications link is described which connects the grain delivery system to a remote computer.Type: GrantFiled: October 2, 1992Date of Patent: September 13, 1994Assignee: SarTec CorporationInventors: Steven J.

Patent number: 5279838Abstract: A method of treating livestock animal feed grains by the addition thereto of a sarsasaponin as a wetting agent in conjunction with the mechanical processing to which feed grains are subjected. A preferred sarasasaponin is that extracted from the Yucca plant. Preferably the sarsasaponin is applied from a liquid medium. The sarsasaponin facilitates moisture uptake by the grain, making it more stable, more palatable and more digestible. When fed to livestock, faster weight gains are obtained with less feed. The wetting agent is desirably added to the grain prior to processing by grinding or rolling and steam flaking.Type: GrantFiled: September 26, 1984Date of Patent: January 18, 1994Assignee: SarTec CorporationInventor: Larry C.
