Abstract
Abstract The present invention provides a method for the direct solvent extraction of oil from oil seeds to produce a low-fat proteinaceous material which comprises, wet heat conditioning oil bearing seeds to a moisture content of from 6 to 12%, flaking said wet heat conditioned oil seeds, dry heat conditioning said flaked oil seeds to a moisture content of from 1.9 to 6%, and treating said dry heat conditioned flakes with a solvent for the removal of the oil contained in said flakes.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
104 words
A method for the direct solvent extraction of oil from peanuts to produce a low-fat proteinaceous material which comprises, wet heat conditioning at a temperature of from 160° to 240° F whole peanuts, peanut splits, peanut granules, or cracked peanuts to a moisture content of more than 6 but less than 12%, flaking said wet heat conditioned peanuts, dry heat conditioning said flaked peanuts to a moisture content of from 1.9 to 6% and treating said dry heat conditioned flakes with a solvent selected from the group consisting of alcohols, ketones, hydrocarbons, and halogenated hydrocarbons, for the removal of oil contained in said flakes.
Claim 2
Independent Claim
104 words
A method for the direct solvent extraction of oil from peanuts to produce a low-fat proteinaceous material which comprises, wet heat conditioning at a temperature of from 160° to 240° F whole peanuts, peanut splits, peanut granules, or cracked peanuts to a moisture content of more than 6 but less than 12%, flaking said wet heat conditioned peanuts, dry heat conditioning said flaked peanuts to a moisture content of from 1.9 to 6% and treating said dry heat conditioned flakes with a solvent selected from the group consisting of alcohols, ketones, hydrocarbons, and halogenated hydrocarbons, for the removal of oil contained in said flakes.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein the wet heat condition is affected at a temperature of from 160° to 240° F for from 2 to 45 minutes.
Claim 4
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are whole peanuts.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are peanut splits.
Claim 6
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are peanut granules.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are cracked peanuts.
Claim 8
Dependent Claim
10 words
The method of claim 1 wherein the solvent is hexanes.
Claim 9
Dependent Claim
24 words
The method of claim 1 wherein said solvent is acetone, ethyl alcohol, isopropyl alcohol, methylene chloride, trichloroethane, trichloroethylene, tetrachloroethylene, fluorinated hydrocarbons or chlorinated hydrocarbons.
Claim 10
Dependent Claim
16 words
The method of claim 1 wherein the wet heat conditioned peanuts are cooled prior to flaking.
Claim 11
Dependent Claim
18 words
The method of claim 1 wherein the flakes are treated with a solvent in a stationary bed extraction.
Claim 12
Dependent Claim
18 words
The method of claim 1 wherein the flakes are treated with a solvent in a counter flow process.
Claim 13
Dependent Claim
18 words
The method of claim 1 wherein the flakes are treated with a solvent in a cross flow process.
Claim 14
Dependent Claim
15 words
The method of claim 1 wherein the flakes are treated with the solvent under vacuum.
Claim 15
Dependent Claim
20 words
The method of claim 1 wherein the temperature of the solvent is maintained at a temperature of about 140° F.
Claim 16
Dependent Claim
25 words
The method of claim 1 wherein the flakes are treated with a solvent which is maintained at a temperature of between 75° and 140° F.
Claim 17
Dependent Claim
27 words
The method of claim 1 wherein the flakes are treated with a solvent which comprises a mixture of solvents for the removal of oil in the peanut.
Claim 18
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are blanched peanuts.
Claim 19
Dependent Claim
11 words
The method of claim 1 wherein the peanuts are unblanched peanuts.
Claim 20
Dependent Claim
34 words
The method of claim 1 wherein the dry heat conditioning is performed by rapid drying using a forced heating system to yield the product with a final moisture content of from 2.5 to 4%.
Claim 21
Dependent Claim
44 words
The method of claim 1 wherein the wet heat conditioning is affected at a temperature of from 200° to 220° F for 10 to 20 minutes to wet heat condition the peanuts to a moisture content of from 8 to 11% prior to flaking.
Claim 22
Dependent Claim
22 words
The method of claim 1 wherein the wet heat conditioning plasticizes the oil seed meat while keeping protein denaturation at a minimum.
