Abstract
A method and apparatus (34) for recovering cotton seed from the lint in batch quantities for planting purposes. The system utilizes a dilute acid (12) approach and provides for gradual mixing of the fuzzy seed (11) and a dilute acid solution followed by batch drying and hydrolysis in a rotating drum (70) reaction chamber (34) in which heated air (36) at a controlled temperature is circulated. The process conditions and the flight pattern of the fuzzy seed within the rotating drum are controlled to avoid trauma to the seed (58) and thereby assure suitability of the recovered seed for planting purposes.
Claims
1. A batch method for removing lint from fuzzy cotton seed which is to be used for planting purposes comprising: selecting a batch quantity of fuzzy cotton seed which is to be delinted; forming a first feed stream of a dilute acid solution; forming a second feed stream of fuzzy cotton seed from said batch quantity from which lint is to be removed; merging the flows of said first and second feed streams at an inlet end of an extended flow path to form a composite stream at said inlet end containing said dilute acid first feed stream and said fuzzy cotton seed second feed stream; gently mixing said composite stream from said inlet end along said extended flow path to gradually blend said first and second flow streams together and thereby gradually saturate the lint on said fuzzy cotton seed with said dilute acid solution along the length of said extended flow path from said inlet end thereof to an exit end thereof; discharging the mixed composite stream of dilute acid solution saturated fuzzy cotton seed at said exit end of said extended flow path in said selected batch quantity into a reaction chamber having a rotatable drum mounted therein; circulating heated air through said rotatable drum from an inlet opening through a discharge opening while continuously rotating said drum with said batch quantity of cotton seed therein; controlling the temperature of said heated air such that the temperature of the heated air at said discharge opening is below the level at which heat 26
damage to the suitability of the seed for planting could occur; evaporating the water in the dilute acid solution absorbed in the lint on said fuzzy seed by circulating said heated air in said reaction chamber to concentrate the acid and thereby cause hydrolyzation of the lint on said fuzzy seed; entraining the hydrolyzed lint in the circulating heated air to remove said hydrolyzed lint from said reaction chamber through said discharge opening; and separately removing the batch quantity of delinted seed from said reaction chamber after said batch quantity has been delinted.
2. A batch method for removing lint from fuzzy cotton seed as set forth in claim 1 wherein said dilute acid solution is concentrated to be of a concentration of acid of not more than about 10%.
3. A batch method for removing lint from fuzzy cotton seed as set forth in claim 2 wherein the acid in said dilute acid solution is selected to be a dilute solution of sulfuric acid.
4. A batch method for removing lint from fuzzy cotton seed as set forth in claim 1 wherein the temperature of said heated air at said discharge opening is controlled to not exceed about 130°F.
5. A batch method for removing lint from fuzzy cotton seed as set forth in claim 1 wherein the volume flow rate of said heated air is selected to be less than about 5,000 cubic feet per minute.
6. A batch method for removing lint from fuzzy cotton seed as set forth in claim 1 wherein the batch quantity of said dilute acid saturated fuzzy cotton seed contained in said drum is selected to be not more than about 4,000 pounds.
7. A batch method for removing lint from fuzzy cotton seed as set forth in claim 1 in which the flight 2 7
pattern of the seed within said drum is controlled to cause the seed falling from the top of said drum during the rotation thereof to fall back onto the seed mass within said drum to thereby avoid substantial impact of the falling seed with the internal surfaces of said drum.
8. A batch method for removing lint from fuzzy cotton seed as set forth in claim 7 in which said flight pattern is controlled by means which include internal guide vanes extending radially inwardly from the periphery of said drum.
9. A batch apparatus for removing lint from fuzzy cotton seed which is to be used for planting purposes comprising: seed delivery means for delivering a batch quantity of fuzzy seed to be delinted; pumping means for forming a first feed stream of a dilute acid solution; seed feeder means for forming a second feed stream of fuzzy cotton seed from the batch quantity of fuzzy seed delivered by said seed delivery means and from which lint is to be removed; dilute acid applicator means forming an elongated flow path extending from an inlet end thereof to an exit end thereof for gradually applying dilute acid solution to said fuzzy seed; said dilute acid applicator means including merging means at the inlet end thereof for merging the flows of said first and second feed streams at said inlet end of said extended flow path for forming a composite stream at said inlet end containing said dilute acid first feed stream and said fuzzy cotton seed second feed stream; said dilute acid applicator means also including mixing means extending along said extended flow path for gently mixing said composite stream from said inlet 2 8
end along said extended flow path to gradually blend said first and second flow streams with each other and thereby gradually saturate the lint on said fuzzy cotton seed with said dilute acid solution along the length of said extended flow path from said inlet end thereof to an exit end thereof; said dilute acid applicator means further including discharge means for discharging the mixed composite stream of dilute acid solution saturated fuzzy cotton seed at said exit end of said extended flow path; a reaction chamber having a rotatable drum mounted therein and being connected to receive dilute acid saturated fuzzy seed from said discharge means into said rotatable drum; means for rotating said drum and means for circulating heated air through said rotatable drum from an inlet opening through a discharge opening while continuously rotating said drum; air temperature control means for controlling the temperature of said heated air to evaporate the water in said dilute acid solution and thereby cause hydrolization of the lint on said fuzzy seed and for limiting the temperature of the heated air at said discharge opening at a level below that at which heat damage to the suitability of the seed for planting could occur; means for removing the hydrolyzed lint from said reaction chamber; and means for removing the delinted seed from said reaction chamber.
10. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 9 in which said rotatable drum further comprises means for directing the flight path of fuzzy seed within said drum to cause 2 9
the seed to fall back on itself as it is dropped from the top of the drum during the rotation of the drum.
11. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 10 in which said means for directing the flight path of fuzzy seed within said drum comprises a plurality of guide vanes extending radially inward from the periphery of said drum for guiding the flight path of the seed within the drum during the delinting process to cause the seed to fall back onto itself during the rotation of said drum and thereby cushion the fall of the seed and minimize impact of the seed with the walls of said drum.
12. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 11 in which the number of said guide vanes is fifteen or less.
13. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 11 in which said guide vanes extend radially inward by less than one-third the radius of said drum.
14. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 9 in which the axis of rotation of said drum is inclined with respect to the horizontal to facilitate movement of the seed from one end of the drum to the other.
15. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 14 in which said axis of rotation is inclined by 10° or less with respect to the horizontal.
16. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 9 in which said air temperature control means includes means for limiting the temperature of the heated air at said discharge opening to about 140°F or less.
17. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 9 in which said means for rotating said drum includes means for regulating the rotational speed of said drum at a substantially constant speed within the range of less than about thirty revolutions per minute.
18. A batch apparatus for removing lint from fuzzy cotton seed as set forth in claim 9 in which said means for rotating said drum includes means for regulating the rotational speed of said drum at a substantially constant speed within the range of about eighteen to about twenty two revolutions per minute.
