Abstract
System for and method of producing a pure starch slurry and alcohol by using combined corn wet and dry milling processes. A simple and lower cost process to obtain starch inside floury endosperm is provided. The starch can be highly purified to meet green technology process needs. The remaining starch inside the corn kernels can be used as feedstock for alcohol production and to produce valuable co-products such as oil and various animal feeds.
Claims16
A wet mill process for producing a purified starch slurry comprising:
- steeping corn kernels;
- grinding the corn kernels to generate corn components comprising starch only from floury endosperm of the corn kernels, germ, grits and fiber, wherein the starch is >10% by weight of the corn components;
- performing germ separation to separate the germ from a first portion of the corn components having the starch, the grits and the fiber;
- and
- separating the starch from the first portion to generate a starch portion having a purity with less than 5% by weight of protein using a device selected from a three or more sectional paddle screen and a second portion of the corn components, wherein the second portion has a fiber >30% by weight of the second portion.
