Abstract

Abstract A process for the separation of a comminuted oat fraction from an admixture thereof with solvent is disclosed. An admixture of the fraction and the solvent is subjected to a high voltage electric field between an anode and a cathode, thereby depositing at least part of the comminuted oat fraction on at least the anode. The solvent is either an aliphatic hydrocarbon containing from 5 to 8 carbon atoms or a normally liquid chlorofluorocarbon containing 1 or 2 carbon atoms. In a preferred embodiment the fraction is a fraction of high protein content and the deposit is only on the anode. In another embodiment the fraction is in the form of a dispersion, e.g. fines, in the solvent.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 102 words
A process for the separation of a comminuted oat fraction from an admixture thereof with an aliphatic hydrocarbon solvent containing from 5 to 8 carbon atoms or a normally liquid chlorofluorocarbon containing 1 or 2 carbon atoms, comprising the steps of: (a) subjecting the admixture to the influence of a high voltage d.c. electric field, said admixture being in the form of a slurry and said electric field being formed between an anode and a cathode, and thereby depositing at least part of the comminuted oat fraction on at least the anode, and (b) separating the part so deposited from said admixture.
Claim 2
Dependent Claim 102 words
A process for the separation of a comminuted oat fraction from an admixture thereof with an aliphatic hydrocarbon solvent containing from 5 to 8 carbon atoms or a normally liquid chlorofluorocarbon containing 1 or 2 carbon atoms, comprising the steps of: (a) subjecting the admixture to the influence of a high voltage d.c. electric field, said admixture being in the form of a slurry and said electric field being formed between an anode and a cathode, and thereby depositing at least part of the comminuted oat fraction on at least the anode, and (b) separating the part so deposited from said admixture.
Claim 3
Dependent Claim 22 words
The process of claim 1 in which the high voltage electric field has an intensity in the range of about 1-20 kV/cm.
Claim 4
Dependent Claim 20 words
The process of claim 1 in which the comminuted oat fraction is deposited on both the anode and the cathode.
Claim 5
Dependent Claim 17 words
The process of claim 1 in which the cominuted oat fraction is only deposited on the anode.
Claim 6
Dependent Claim 18 words
The process of claim 2 in which the comminuted oat fraction is in the form of comminuted groats.
Claim 7
Dependent Claim 22 words
The process of claim 2 in which the comminuted oat fraction is in the form of a fraction derived from comminuted groats.
Claim 8
Dependent Claim 18 words
The process of claim 6 in which the comminuted oat fraction is a fraction of high protein content.
Claim 9
Dependent Claim 18 words
The process of claim 6 in which the comminuted oat fraction if in the form of a dispersion.
Claim 10
Dependent Claim 15 words
The process of claim 6 in which the solvent is substantially free of oat oil.
Claim 11
Dependent Claim 25 words
The process of claim 2 in which the solvent is selected from the group consisting of pentane, hexane, heptane, cyclohexane and chlorofluorcarbons, and mixtures thereof.
Claim 12
Dependent Claim 24 words
The process of claim 6 in which the solvent is selected from the group consisting of pentane, hexane, heptane and cyclohexane, and mixtures thereof.
Claim 13
Dependent Claim 12 words
The process of claim 6 in which the solvent is a chlorofluorocarbon.
Claim 14
Dependent Claim 22 words
The process of claim 6 in which the high voltage electric field has an intensity in the range of about 5-15 kV/cm.
Claim 15
Dependent Claim 13 words
The process of claim 4 in which the anode is a rotating drum.
Claim 16
Dependent Claim 31 words
The process of claim 4 in which step (b) is followed by a step (c) in which the fraction deposited on the anode is contacted with solvent essentially free of oil.
