Patents by Inventor John Griebat

John Griebat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7104479
    Abstract: The present invention is a short flow milling process wherein finished product is rapidly isolated and removed from the milling process flow regime at early stages. The minimization of handling and the minimization or elimination of intermixing streams of various size gradations prevents size contamination that otherwise necessitates further sifting. Component parts are eliminated along with the accompanying handling and transfer equipment to create a compact and efficient milling regime. The size reductions enable the invention to be practiced in a mobile form. Therefore, the present invention relates also to a method for providing a mobile mill process.
    Type: Grant

  • Patent number: 6550700
    Abstract: The present invention is a test milling method to determine the suitability of a grain for use in the derivation of desired end products. A full scale mill is simulated through a bench scale application wherein only a small portion of grain is required to conduct the test in contrast to testing protocols which employ full scale equipment. By utilizing the small scale simulations, hybrid varieties may be tested for total grit extraction and total yield well in advance of the many seasons that it takes to develop market quantities of a hybrid. The invention also relates to a method for determining which items of data collected are needed to accurately predict the total yield and grit extraction % and subsequently applying these limited data points in a shortened simulation to reduce the number of steps required in the test protocol. Data obtained from such tests may be used to direct hybrid research and select the best hybrids and shipments for the desired milling process.

  • Patent number: 6409105
    Abstract: A table separator is provided, wherein the table separator comprises a plurality of solid-bottomed trays and a plurality of dimples for facilitating separation of degerminated corn into endosperm and germ fraction, the dimples being aligned in linear juxtaposition on the surface of the trays and having a center portion raised with respect to the perimeter of the dimples.
