[0047] Example 1

[0048] Processing corn with high oil content by slicing method

[0049] Use Perten bulk near infrared (NIR) seed tester (TM) (9100-HF type) Perten Instruments, POBox 7398, Reno, NV 89510, to screen each corn of yellow molar corn with total oil content higher than about 7% oil Spike the shelled kernels. In the Brimrose Seedmeister (TM) individual kernel NIR tester (Brimrose Corp., Baltimore, MD), kernels with an oil content of at least 13% were further screened from corn kernels with an oil content of at least 7%. When these kernels are stored, the moisture content is about 13.5%. During processing, the water content of the seeds is about 10%.

[0050] The whole corn kernels are made into flakes with a small flake device equipped with a two-inch stainless steel rod and pan. The whole corn kernel sample was passed through the roller 4 times to obtain a final flake thickness of about 0.01 inch. Use hot (60-65°C) n-hexane and Kimble(TM) 585050 Soxhlet extractor to e...

Abstract

A commercial-scale method for processing corn grain includes the steps of flaking corn grain having a total oil content of at least about 8% and extracting a corn oil from the flaked corn grain. Such a method can be effectuated by processing the high oil corn grain using methods and equipment typically used to process soybeans and other similar oilseed types. In this way, processing plants that flake oilseeds can be used to extract corn oil from corn.

Description

Invention field [0001] The present invention relates to the processing of corn. Specifically, the present invention relates to processing corn to produce corn oil and / or corn meal. Background of the invention [0002] For many reasons, including food and industrial applications, people grow corn (Zea mays L). Corn oil is one of many useful products derived from corn. Commercial processing The plant uses conventional methods to extract corn oil, usually by dividing corn seeds into its individual components, such as endosperm, germ, apical bud and pericarp, and then extracting corn oil from corn germ components. [0003] Although the precise processing steps and device types vary from plant to plant, commercial corn processing can be divided into wet milling or dry milling. In general, wet grinding is a complex process involving many steps. In the separation of corn oil components, the corn is first soaked in an elevated temperature water / sulfur dioxide (SO2) mixture, and then pass...
