Embodiment Construction

[0017] Corn wet milling equipment converts corn kernels into several different co-products such as germ (for oil extraction), gluten feed (high fiber animal feed), gluten meal (high protein animal feed) and starch-based Products (such as ethanol or butanol, high fructose corn syrup, or food and industrial starches). Typical corn wet milling equipment may include a fiber separation step in which a slurry of water, gluten and starch is passed through a series of wire meshes to separate the fiber from the starch and gluten and to wash the fiber so that it does not Contains gluten and starch. Similarly, a typical dry milling process may include a centrifugation step in which the fibers are similarly filtered or separated from the slurry. Those of ordinary skill in the art will appreciate that typical corn wet and dry milling processes can be manipulated and modified, if desired.

Abstract

The invention relates to a multi-zoned paddle screen apparatus (100) which is disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus includes a housing (106) having first and second zones (108a, 108b) situated adjacent one another along a length (L) of the housing (106). First and second screen sections (102a, 102b) having a plurality of openings (104) may be situated lengthwise within the housing (106) corresponding with the first and second zones (108a, 108b), respectively. The first and second screen sections (102a, 102b) have a circular cross-section, and the second screen section (102b) has a larger diameter than the first screen section (102a). An elongated shaft (130) situated lengthwise within the screen sections (102a, 102b) includes first and second conveyors (128a, 128b), which correspond with the first and second zones (108a, 108b), respectively, having a plurality of paddles (132). Each conveyor (128a,128b) is configured to move material in a direction along a length of the screen (102a, 102b). There may be more than two zones (108a, 108b).

Description

technical field [0001] The present invention relates generally to separating material from a liquid medium, and more particularly to an apparatus and method for separating fibers from a slurry or other liquid medium. The invention also relates to sorting particles according to size and / or density. Background technique [0002] A wide range of industrial applications requires the separation or isolation of a total material into several constituent parts, for example by some type of filtration process using a liquid medium. Once filtered, the separated components and / or total material, as well as the remainder of the liquid medium, may be further processed to obtain one or more desired products. By way of example, various methods of producing alcohol from grain may entail separating the fiber component of the grain from the starch and / or other components of the grain. For example, the corn wet milling process separates fiber from the starch in the corn and then uses the star...
