water Quality Management <br /> French Oils, LLC <br /> 1. Description of the products) and the process flow diagram that is used to make the <br /> products. <br /> Product 1: Corn Oil. The corn oil produced at the proposed French Oils facility would <br /> be used primarily for human consumption. However, prior to use, the oils must be <br /> further processed in order to bring it into food grade. As a secondary option/outlet, <br /> this oil could be sold for refinement as biofuel. under either condition, this oil• <br /> will need to be further processed and refined. French Oils .is only proposing an <br /> initial mechanical `crushing, (extracting) operation, which does not involve the use of <br /> any chemicals or even process water. <br /> Product 2: , Corn Germ Meal. This meal is a bi-product that is created once the oils <br /> are removed. This product does contain residual amounts of corn oil, as well as being <br /> high in proteins and other nutrients. This is used. as a feedstock, primarily for <br /> cattle and dairy livestock. This bi-product would be sold directly to these livestock <br /> operators for feed. <br /> - - -o , ­.x - . <br /> T`""^`- — -` �4 D Shipped for lurcher' - <br /> 1) Oil Extraction Process Periodically,'fines'and oil are re-processed processing for <br /> (mixed back into Corn Germ)to Human Consumption <br /> recapture oil and.clear Settling Tanks or Biodiesel <br /> Oh pumped into <br /> _.

(McKenna) boiler is used to bring up the temperature of <br /> corn .germ prior to crushing (expelling) . This makes the oil more viscous and easier to <br /> separate from the germ. <br /> The boiler itself generates steam that is circulated through a closed system (nothing <br /> is added to the product) and integrated into the process during the drying/conditioning <br /> stage.
