摘要： A method for recovering supercritical extractant, such as supercritical CO2, from a mixture containing the supercritical extractant and a solute is disclosed, which includes contacting the mixture with a molecular sieve membrane at a temperature and a pressure in a critical region of the extractant and near a critical point of the extractant so that a permeate rich in the extractant and a retentate having a enriched concentration of the solute in the extractant are generated. The molecular sieve membrane has a pore size significantly larger than a size of the extractant provided that the pore size is less than and close to sizes of clusters formed of the solute and the extractant at the temperature and the pressure.

摘要： A simple, reliable process for decaffeinating green coffee beans to a high degree while avoiding denaturation of the green coffee beans includes wetting the green coffee beans to a high water content of 35-50%-wt.; compressing the beans in a pressure chamber for a period of a few minutes to several hours in an atmosphere comprised of a supercritical fluid which is a gas at STP, at a temperature ranging from 20.degree. to 80.degree. C. under a critical pressure ranging from 75 to 300 bar; decompressing the wetted beans from critical pressure p.sub.c to a pressure p for which p.sub.c p.gtoreq.p.gtoreq.1 bar abruptly or in the space of a few minutes, while avoiding freezing the green coffee beans; washing with water or with the supercritical fluid for selective extraction of the caffeine; repeating the process one or more times; centrifuging; drying; and roasting the beans. Further, caffeine is recovered in a known manner from the washing medium.

摘要： A screen is mounted in an apparatus for contacting particulate solids with a fluid. The apparatus comprises an elongate column for holding a bed of particulate solids for contact with a fluid, the column being designed to be oriented substantially vertically in use and having a fluid inlet near the bottom for admitting a fluid into the column and a fluid outlet near the top for permitting the fluid to exit the column after passing upwardly through a bed of particulate solids in the column. The purpose of the screen is to screen solids from the fluid exiting the column through the fluid outlet. The screen comprises a plurality of vertical screen wires, and the screen is located within the column such that all of the fluid passing through the column passes through the screen and then through the fluid outlet. Each pair of adjacent vertical screen wires defines a substantially vertical screen slot therebetween. The opening of each vertical screen slot at the surface of the screen which is upstream in the sense of a fluid flowing through the column, passing through the screen, and exiting through the outlet during operation of the column, has a width suitable for screening solids from the exiting fluid and has a length which is substantially greater than its width.

摘要： An apparatus for a supercritical fluid-solid bed process such as for decaffeinating green coffee beans including an elongated cylindrical vessel having a top and bottom. The solids accumulate to form a fluid-solids bed on the bottom of the vessel which includes a central bottom opening, a valve for periodically allowing flow of the solids through the bottom opening and a frustoconical bottom wall. A flow promoting insert having a lower conical wall is provided circumjacent to but spaced from the frustoconical bottom wall. The lower conical wall is provided with a rougher surface than the adjacent frustoconical bottom wall to promote uniform flow of solids. The fluid initially flows through the solids counter-current to the solid flow and is introduced to the vessell through means located above the flow promoting insert.

摘要： A method of continuously decaffeinating moistened, green coffee solids with supercritical carbon dioxide. Moistened, green coffee beans are moved periodically through an extraction vessel and contacted with continuously flowing supercritical carbon dioxide which extracts caffeine from the moist, green coffee beans. Caffeine is removed from the supercritical carbon dioxide by counter-current contact with wash water in an open vessel. The caffeine-depleted supercritical carbon dioxide is recirculated back to the extraction vessel and the caffeine-bearing wash water is subjected to concentration by reverse osmosis. Acidic, substantially caffeine-free permeate is directed back to the extraction system as wash water, or to moisturize the green coffee beans prior to extraction, or both.

摘要： A method of extracting caffeine from green coffee beans whereby an essentially caffeine-free supercritical fluid is continuously fed to one end of an extraction vessel containing green coffee beans and caffeine-laden supercritical fluid is continuously withdrawn from the opposite end. A portion of decaffeinated beans is periodically discharged while a fresh portion of undecaffeinated beans is essentially simultaneously charged to the extraction vessel. The caffeine-laden supercritical fluid is fed to a countercurrent water absorber. Supercritical carbon dioxide is the preferred supercritical fluid. The method of the present invention is more efficient than batch processes and produces an improved decaffeinated coffee.
