ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to fuzzy cottonseed processing and, more specifically, to a method for producing pelletized whole fuzzy cottonseed. The method comprises means for selectively delivering a measured amount of linted cottonseed to a screw extruder. The screw extruder having a bore and screw that decreases in diameter from one distal end to the other. Thereby, the linted cottonseed is subjected to predetermined increases in pressure and ground to a pasty oatmeal-like consistency before being extruded at the output end to a delivery system feeding the pellet forming mechanism having as its output pelletized linted cottonseed.
2. Description of the Prior Art
There are other linted cottonseed processes designed for using cottonseed as a food. Typical of these is U.S. Pat. No. 3,972,861 issued to Gardner, Jr. et al. on Aug. 3. 1976.
Another patent was issued to Worthman et al. on Jul. 5, 1977 as U.S. Pat. No. 4,034,120. Yet another U.S. Pat. No. 4,055,680 was issued to Duke on Oct. 25, 1977 and still yet another was issued on Dec. 13, 1977 to De Santis as U.S. Pat. No. 4,062,988.
Another patent was issued to Hipp et al. on Apr. 11, 1978 as U.S. Pat. No. 4,084,007. Yet another U.S. Pat. No. 4,132,807 was issued to Duke on Jan. 2, 1979. Another was issued to Kadan et al. on May 6, 1980 as U.S. Pat. No. 4,201,709 and still yet another was issued on Jul. 21, 1981 to Gray et al. as U.S. Pat. No. 4,279,811.
Another patent was issued to Coles et al. on Apr. 20, 1993 as U.S. Pat. No. 5,204,102. Yet another U.S. Pat. No. 5,363,754 was issued to Coles et al. on Nov. 15, 1994 and still yet another was issued on May 12, 1998 to Wedegaertner et al. as U.S. Pat. No. 5,750,466.

Issued: Aug. 3, 1976
An edible high-protein flour is produced by an improved process. Cottonseed meats are dried, and then comminuted in a wide chamber mill having certain specifications which prevent rupturing the pigment glands of the cottonseed. This improvement is correlated with liquid cyclone separation followed by solids recovery steps, thus comprising an improved process which consistently yields an edible cottonseed protein concentrate.

The pelleting of fibrous agricultural material, such as beet pulp is facilitated by the incorporation of a mixture of expanded vermiculite and/or finely divided vermiculite ore with an organic material which may be animal fat or a vegetable oil product such as cottonseed oil.

Molasses, a fatty acid soap former such as yellow grease, a hard metallic soap former such as calcium oxide and a natural protein source such as cottonseed meal are blended and mixed to obtain a nutrient composition which sets to a hard block.

Inventor: James P. Hipp
Issued: Apr. 11, 1978
An improved process for producing a high quality, edible meal product from cottonseed by releasing oil under conditions whereby unruptured gossypol cells are loated out with the oil flow and immediately separated from the remaining solids. Sufficient gossypol is removed in the cooking step of the extraction phase by a simple, low temperature heat and moisture treatment so that the final meal product rendered is safe and nutritious for human consumption, yet produced at lower cost than prior art methods. The dry, decortiated oleaginous material is treated in a flow down cooker where heat and moisture are added for removal of a significant portion of the oil and gossypol therein, after which the material is mixed with a solvent for removal of the major portion of the remaining oil and gossypol. The material is then separated from the mixture of solvent and removed oil and gossypol in an extracting or washing apparatus after which the material is treated in a desolventizer or removal of the remaining solvent, leaving a meal with a low gossypol and fat content.

U.S. Pat. No. 4,201,709
Inventor: Ranjit S. Kadan et al.
Issued: May 6, 1980
A low-gossypol, high-protein flour is produced by a process which utilizes conventional solvent extraction equipment with a certain series of steps, culminating at a oint where a defatted, milled, cottonseed flour mixture is rendered edible for human consumption by the separation of the gossypol-containing portion.
U.S. Pat. No. 4,279,811
Inventor: Marie S. Gray et al.
Issued: Jul. 21, 1981
A low gossypol, high protein cottonseed product is produced by passing cottonseed meal through a certain series of steps utilizing conventional solvent extraction quipment, and culminating at a point where the cottonseed meal is rendered edible—for human consumption and animal feed—by disruption of gossypol glands and xtraction of gossypol pigments.

Inventor: Thomas C. Wedgegaertner et al.
Issued: May 12, 1998
Linter-bearing cottonseed covered with a coat of starch optionally containing one or more biologically related materials selected from vitamins, feed supplements, oils, fats, urea, rodent repellants, insect repellants, medications, anti-germination agents, and preservatives, and a method for preparing it is taught herein. Starch coated cottonseed is useful as an animal feed and as planting stock. The starch coating allows the cottonseed to be used in conventional feed handling and seed linting equipment.
While these linted cottonseed processes may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
