Filed:

May 2, 2002

Appl. No.:

10/136378

Inventors:

Richard Wildasin - Lockport IL, US
James Forbes - Lockport IL, US
Raymond Robey - Naperville IL, US
Armand Paradis - Naperville IL, US

International Classification:

A23L003/16

US Classification:

426/521000

Abstract:

A continuous method using gaseous carbon dioxide or a pressurized flow of liquefied carbon dioxide is described to reduce microbial and/or enzymatic activity in a liquid product. The carbon dioxide is combined with a pressurized flow of the liquid product, or the mixture is pressurized after the mixture is formed. The pressure and temperature in the flow regions are maintained at a level which is sufficient to keep the carbon dioxide in a continuous liquid state, but which does not freeze the liquid product. The pressurized mixture of the carbon dioxide and liquid product flows through a reaction zone for a sufficient time to reduce harmful microorganisms and/or inactivate enzymes and then enters one or more expansion stages wherein the pressure of the mixture flow is sufficiently decreased to vaporize the carbon dioxide for separation from the liquid product. If necessary, heat is applied in at least one of the expansion stages to prevent a freezing of the mixture.

Abstract:

An apparatus and process for cleaning residual matter, photoresist and other foreign materials off wafers, substrates and semiconductor work pieces including photomasks, compact discs, flat panel displays using megasonic acoustic wave action techniques in conjunction with supercritical fluid cleaning processes, and in particular, for coupling megasonics techniques with supercritical carbon dioxide processing with co-solvents and surfactants, using cycles of soak, rapid decompression and flushing, to improve cleaning capability and to remove submicron particles from the surfaces of wafers.

Appl. No.:

9/276668

Inventors:

Raymond John Robey - Naperville IL

Assignee:

Praxair Technology, Inc. - Danbury CT

International Classification:

B04B 506

US Classification:

494 22

Abstract:

A process for extracting a component from liquids using dense phase gases or supercritical fluids (dense phase solvent). The process contacts a liquid and the dense phase solvent in a rotating mixer to dissolve a desired fraction into the dense phase solvent to form a loaded solvent. Furthermore, the mixer separates the loaded solvent from the remaining raffinate. Then the rotating mixer discharges the loaded solvent and raffinate. Decreasing pressure on the loaded solvent converts the loaded solvent into a gas and the desired fraction to liberate the desired fraction from the gas.

International Classification:

A23L 1217
C11B 300

US Classification:

426417

Abstract:

A method of making reduced oil content food chip products, such as potato chips and corn chips, includes circulating liquid carbon dioxide, over the food chip products to extract oil. Reduction of oil content to less than 50% of its initial value, including reductions to 25%, may be achieved while retaining flavor and texture comparable to conventional deep fried chips having an oil content of 30% to 40%. The oil which is recovered from the liquid carbon dioxide used for extraction has an appearance and quality which are substantially the same as virgin frying oil and may be reused to deep fry chips.

International Classification:

A23F 520

US Classification:

426427

Abstract:

The present invention provides a method of decaffeinating green coffee beans without adversely affecting their acidity or the flavor of coffee beverages produced from them. The invention also relates to a method useful with supercritical decaffeination, in particular with caffeine extraction using supercritical carbon dioxide. In accordance with the invention, green coffee beans are subjected to a treatment by contacting them with an acidic fluid containing an organic acid that is not soluble in supercritical carbon dioxide, preferably an aqueous citric acid solution, prior to or simultaneously with decaffeination.
