Abstract
Abstract A method and apparatus of desolventizing previously solvent extracted milled rice and, in certain embodiments of the invention, desolventizing of the bran removed from the rice. The method and apparatus contemplates using a desolventizing gaseous medium comprising inert gas as the major component thereof wherein the gaseous medium is contacted with the rice when at a temperature in the range from about 100* F. to about 150* F., whereby the solvent is vaporized from the rice at a relatively low temperature, thereby preserving the quality of the rice. The gaseous medium with the vaporized solvent entrained therein is subsequently condensed to remove the solvent therefrom and the medium is subsequently heated and recycled.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
247 words
In apparatus for desolventizing solvent extracted milled rice, the combination comprising: a housing arranged for passage of said rice therethrough in a semi-fluidized state, said housing having inlet and outlet means for passing a desolventizing gaseous medium comprising inert gas as the major component therethrough and in intimate contact with said rice therein to thereby vaporize solvent from said rice; and a system for generating and recycling said medium through said housing, said system comprising; a gas generator for generating said inert gas; a heater for heating said medium to a temperature in the range of from about 100* F. to about 150* F. upon introduction into said hOusing; first conduit means for conducting said medium from said heater to said inlet means of said housing; a compressor connected to receive said medium from said outlet means of said housing, and to deliver said medium under pressure to thereby provide a driving force for said medium through said housing; second conduit means arranged to receive said pressurized medium from said compressor; condenser means connected to receive said medium transmitted by said second conduit means for condensing solvent vapors from said medium; third conduit means for conducting said medium from said condenser to said heater; and valve means connected to be responsive to the pressure differential between said medium in said first and second conduit means and arranged for delivering additional inert gas generated by said generator to said medium when said pressure differential exceeds a predetermined limit.
Claim 2
Dependent Claim
247 words
In apparatus for desolventizing solvent extracted milled rice, the combination comprising: a housing arranged for passage of said rice therethrough in a semi-fluidized state, said housing having inlet and outlet means for passing a desolventizing gaseous medium comprising inert gas as the major component therethrough and in intimate contact with said rice therein to thereby vaporize solvent from said rice; and a system for generating and recycling said medium through said housing, said system comprising; a gas generator for generating said inert gas; a heater for heating said medium to a temperature in the range of from about 100* F. to about 150* F. upon introduction into said hOusing; first conduit means for conducting said medium from said heater to said inlet means of said housing; a compressor connected to receive said medium from said outlet means of said housing, and to deliver said medium under pressure to thereby provide a driving force for said medium through said housing; second conduit means arranged to receive said pressurized medium from said compressor; condenser means connected to receive said medium transmitted by said second conduit means for condensing solvent vapors from said medium; third conduit means for conducting said medium from said condenser to said heater; and valve means connected to be responsive to the pressure differential between said medium in said first and second conduit means and arranged for delivering additional inert gas generated by said generator to said medium when said pressure differential exceeds a predetermined limit.
Claim 3
Dependent Claim

In apparatus for desolventizing solvent extracted milled rice, the combination comprising: a housing arranged for passage of said rice therethrough in a semi-fluidized state, said housing having inlet and outlet means for passing a desolventizing gaseous medium comprising inert gas as the major component therethrough and in intimate contact with said rice therein to thereby vaporize solvent from said rice; and a system for generating and recycling said medium through said housing, said system comprising; a gas generator for generating said inert gas; a heater for heating said medium to a temperature in the range of from about 100* F. to about 150* F. upon introduction into said hOusing; first conduit means for conducting said medium from said heater to said inlet means of said housing; a compressor connected to receive said medium from said outlet means of said housing, and to deliver said medium under pressure to thereby provide a driving force for said medium through said housing; second conduit means arranged to receive said pressurized medium from said compressor; condenser means connected to receive said medium transmitted by said second conduit means for condensing solvent vapors from said medium; third conduit means for conducting said medium from said condenser to said heater; and valve means connected to be responsive to the pressure differential between said medium in said first and second conduit means and arranged for delivering additional inert gas generated by said generator to said medium when said pressure differential exceeds a predetermined limit.
Claim 4
Dependent Claim
247 words
In apparatus for desolventizing solvent extracted milled rice, the combination comprising: a housing arranged for passage of said rice therethrough in a semi-fluidized state, said housing having inlet and outlet means for passing a desolventizing gaseous medium comprising inert gas as the major component therethrough and in intimate contact with said rice therein to thereby vaporize solvent from said rice; and a system for generating and recycling said medium through said housing, said system comprising; a gas generator for generating said inert gas; a heater for heating said medium to a temperature in the range of from about 100* F. to about 150* F. upon introduction into said hOusing; first conduit means for conducting said medium from said heater to said inlet means of said housing; a compressor connected to receive said medium from said outlet means of said housing, and to deliver said medium under pressure to thereby provide a driving force for said medium through said housing; second conduit means arranged to receive said pressurized medium from said compressor; condenser means connected to receive said medium transmitted by said second conduit means for condensing solvent vapors from said medium; third conduit means for conducting said medium from said condenser to said heater; and valve means connected to be responsive to the pressure differential between said medium in said first and second conduit means and arranged for delivering additional inert gas generated by said generator to said medium when said pressure differential exceeds a predetermined limit.
Claim 5
Dependent Claim
89 words
The invention as claimed in claim 1 including: a second housing arranged for passage therethrough of solvent extracted bran previously removed from said rice, said housing having an inlet and outlet; means for heating and passing a desolventizing gaseous medium comprising inert gas as the major component through said second housing in intimate contact with said bran therein at a desolventizing temperature to thereby vaporize solvent from said bran; and second valve means connected for supplying inert gas from said generator to said medium circulated through said second housing.
Claim 6
Dependent Claim
43 words
The invention as claimed in claim 2 including: a second condenser connected to receive the medium passed through said second housing, whereby said medium used to desolventize said bran is separated from that medium used to desolventize said rice and is separately recycled.
