  • Patent number: 11684930
    Abstract: A quantitative infrared chemical imaging method to determine the concentration of a desired high value product in a milling process is used as a basis to optimize the milling process by changing operational parameters, such as sieve size. In a dry milling process, the method can be used to determine the concentration of purified endosperm within heterogeneous solid particulate mixtures containing endosperm and nonendosperm botanical parts. The imaging component accommodates the analysis of particle size statistics for each component of the mixture, based upon the chemical structural characterization. Timely chemical composition and particle size analyses enables informed selection for the optimization of physical separation for the processing of granular solids. The method involves changing sieves within the sifting apparatus based on chemical imaging to provide smaller or larger screen openings to improve separation of endosperm and nonendosperm material from the ground product.

  • Patent number: 5250313
    Abstract: A degerminating process wherein the grain kernels are crushed from the thin edges toward the center while avoiding crushing of the relatively flat side surfaces. The crushing force fractures the endosperm under and around the germ and squeezes the germ away from the endosperm in a whole condition. A machine for carrying out the degermination includes relatively rotating discs having the corrugations in their facing surfaces in which the kernels are caught and crushed from the thin edges toward the center. An alternative degerminator machine includes a single rotating disc having curved guide vanes on its upper surface for guiding the kernels as they are propelled outwardly by centrifugal force. The vanes orient each kernel with its top or bottom edge in position to impinge upon flat impact surfaces which results in a crushing force applied from the thin edge toward the center of the kernel.
