Definitions

  • the further-broken particles are separated, typically by a sifting process. From there, larger particles are further rolled in a subsequent break roller (and the further-broken particles are again sifted), or they are passed on to drying or cooling steps or additional sifting steps to isolate finished products (flour, meal, grits, etc.). Of course other products may be desired by particular purchasers.
  • the remaining particles that fail to pass the post germ sifting steps are typically sent to a germ handling process (labeled oil recovery in Figure 2).
  • the finer particles obtained from the germ roller siftings are processed in a manner generally similar to the finer particles from the break rollers.
  • a second aspect of the invention provides a method of milling grain kernels, comprising:
  • Finished product grade material is withdrawn from process streams when it is first separated, without further intermixing of already separated streams and without a need for further production sifting. This separation occurs early in the short mill process, preferably as early as separation of the degermination stream.
  • the post-degermination sifter is herein referred to as a "hominy grader.”
  • the hominy grader segments the broken corn into various streams depending on granulation-the size of the product granules.
  • the finer granulated streams, such as low fat meal and flour streams are directed as finished product from the hominy grader to eliminate excessive handling and deterioration of product quality.
  • the meal stock may be directed towards a hammer-mill or flour grinder if greater flour output is desired. By extracting finished product as soon as possible, the mill flow can be greatly reduced as further sifting of an already isolated stream is not required.
  • a first preferred embodiment of the present invention operates as follows.
  • the input corn is cleaned and degerminated prior to arrival at the hominy grader.
  • a number 6, 12, 30, and 62 wire mesh screen is employed to separate the particles from degermination.
  • Alternative screen sizes may be employed to produce finished product having the desired particle size profiles and ranges.
  • the overs (particles that do not pass through) the number 6 screen are directed towards a gravity table via aspiration. From the gravity table, the lighter germ and germ contaminated material is removed and directed to a germ or oil recovery process. It has been found that at or above 95% of the germ is removed from the process stream at this point.
  • the heavier particles from the gravity table are directed to a first break roller.
  • the overs from the number 12 screen of the hominy grader are directed towards a second break roller via aspiration.
  • the overs from the number 30 screen of the hominy grader are directed towards a third break roller via aspiration.
  • the overs from the number 62 screen of the hominy grader are directed onward as finished product meal, whereas those portions that pass the number 62 screen are directed onward as finished product flour.
  • the meal finished product stream can optionally be diverted for grinding in to flour.
