Abstract
Abstract This application is directed to processes involving the use of nonmiscible inert liquid carriers such as halogenated hydrocarbons. The processes are applicable to mixing, agglomerating, coating, dyeing, reorientating, crystallizing, precipitating, reacting and similar types of operations. Examples of products which can be treated by these processes are foods, pharmaceuticals, detergents, fabrics and papers. The inert carrier acts as an expanded matrix to support and disperse such products to facilitate carrying out the indicated operating steps.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
58 words
The process which comprises adding at least two substances, one of which is a solid and one of which is a solvent for the solid, in a liquid carrier which is inert, immiscible, and insoluble with respect to said substances, turbulently mixing said substances and said liquid until said substances interact and separating said substances from said liquid.
Claim 2
Dependent Claim
58 words
The process which comprises adding at least two substances, one of which is a solid and one of which is a solvent for the solid, in a liquid carrier which is inert, immiscible, and insoluble with respect to said substances, turbulently mixing said substances and said liquid until said substances interact and separating said substances from said liquid.
Claim 3
Dependent Claim
13 words
The process of claim 1 wherein said liquid carrier is a halogenated hydrocarbon.
Claim 4
Dependent Claim
10 words
The process of claim 1 wherein said solvent is water.
Claim 5
Dependent Claim
35 words
The process of claim 1 wherein said substances comprise a solid and a liquid which is a wetting agent for said solids and mixing said substances and said liquid carrier until said solids are agglomerated.
Claim 6
Dependent Claim
12 words
The process of claim 4 wherein said solid is a powdered detergent.
Claim 7
Dependent Claim
12 words
The process of claim 4 wherein said solid is a food stuff.
Claim 8
Dependent Claim
11 words
The process of claim 4 wherein said solid is a pharmaceutical.
Claim 9
Independent Claim
94 words
The method of agglomerating solids to produce a substance which is readily dispersed in a liquid which comprises subjecting to turbulent mixing a mixture of (1) said solids, (2) a minor amount of a wetting agent for said solids, and (3) an inert halogenated hydrocarbon which is immiscible with said wetting agent and in which said solid is insoluble, wherein said mixture is prepared by: A. mixing (1) and (3) and then adding (2); or B. mixing (2) and (3) and then adding (1), and separating said solids and wetting agent from said mixture.
Claim 10
Independent Claim
94 words
The method of agglomerating solids to produce a substance which is readily dispersed in a liquid which comprises subjecting to turbulent mixing a mixture of (1) said solids, (2) a minor amount of a wetting agent for said solids, and (3) an inert halogenated hydrocarbon which is immiscible with said wetting agent and in which said solid is insoluble, wherein said mixture is prepared by: A. mixing (1) and (3) and then adding (2); or B. mixing (2) and (3) and then adding (1), and separating said solids and wetting agent from said mixture.
Claim 11
Dependent Claim
13 words
The process of claim 8 wherein said halogenated hydrocarbon is a fluorochlorinated hydrocarbon.
Claim 12
Dependent Claim
11 words
The process of claim 9 wherein said wetting agent is water.
Claim 13
Dependent Claim
12 words
The process of claim 10 wherein said solid is a powdered detergent.
Claim 14
Dependent Claim
18 words
The process of claim 8 wherein said wetting agent is water and said solid is a food stuff.
Claim 15
Dependent Claim
11 words
The process of claim 8 wherein said solid is a pharmaceutical.
Claim 16
Dependent Claim
27 words
The process of claim 13 wherein said wetting agent is a low molecular weight alcohol, said halogenated hydrocarbon is a fluorinated hydrocarbon and said pharmaceutical is aspirin.
Claim 17
Dependent Claim
36 words
The process of claim 12 wherein said foodstuff is selected from the group consisting of sugar, cocoa, coffee, dried fruit juice concentrate and milk solids, wherein the ratio of said foodstuff to water is about 100:1-10.
Claim 18
Independent Claim
73 words
The method of agglomerating solids to produce a substance which is readily dissolved in water which comprises: subjecting to turbulent mixing a mixture of (1) said solids, (2) a minor amount of water, and (3) fluorochlorinated hydrocarbon, wherein said mixture is prepared by: A. mixing (1) and (3) and then adding (2); or B. mixing (2) and (3) and then adding (1), separating the wetted solids from said mixture and drying said solids.
Claim 19
Independent Claim
73 words
The method of agglomerating solids to produce a substance which is readily dissolved in water which comprises: subjecting to turbulent mixing a mixture of (1) said solids, (2) a minor amount of water, and (3) fluorochlorinated hydrocarbon, wherein said mixture is prepared by: A. mixing (1) and (3) and then adding (2); or B. mixing (2) and (3) and then adding (1), separating the wetted solids from said mixture and drying said solids.
