Method And Apparatus For Expanding Tobacco Material

View page
US Patent:
6575170, Jun 10, 2003
Filed:
Nov 27, 2000
Appl. No.:
09/721696
Inventors:
Ravi Prasad - Richmond VA, 23236
International Classification:
A24B 318
US Classification:
131309, 131310
Abstract:
A process for exapanding tobacco employs gaseous impregnant at elevated pressure. Tobacco is passed through a gaseous impregnant atmosphere using mechanical devices (e. g. , pressure locks, pocket feeders). Tobacco gets impregnated with pressurized gaseous impregnant during the âpass-throughâ. Uniformity of impregnation is obtained by passing small batches of tobacco having uniform bulk density, and uniform gas properties at or near the tobacco exit point of the âPass-throughâ. Natural buoyancy of the impregnant gas assures that gas temperature uniformity is achieved quickly and without any elaborate control system, and in a simplified, self controlling and self regulating process. Significant equipment cost and size reduction results. An apparatus that uses the improved process is also provided.

Process And Apparatus For Impregnation And Expansion Of Tobacco

View page
US Patent:
57996652, Sep 1, 1998
Filed:
Dec 19, 1996
Appl. No.:
8/769972
Inventors:
Kwang H. Cho - Midlothian VA
Thomas J. Clarke - Richmond VA
Joseph M. Dobbs - Richmond VA
Eugene B. Fischer - Chester VA
Diane L. Leister - Richmond VA
Jose M. G. Nepomuceno - Beaverdam VA
Walter A. Nichols - Midlothian VA
Ravi Prasad - Midlothian VA
International Classification:
A24B 318
US Classification:
131291
Abstract:
A process for expanding tobacco is provided which employs carbon dioxide gas. Tobacco temperature and OV content are adjusted prior to contacting the tobacco with carbon dioxide gas. The disclosed process is suitable for impregnating and expanding tobacco having a high bulk density. In order to achieve a high bulk density, the tobacco may be compacted or compressed to achieve an increased and more uniform bulk density prior to its impregnation with carbon dioxide. The process may be carried out with a short cycle impregnation in an apparatus according to the invention. A thermodynamic path is followed during impregnation which allows a controlled amount of the carbon dioxide gas to condense on the tobacco. This liquid carbon dioxide evaporates during depressurization helping to cool the tobacco bed uniformly. After impregnation, the tobacco may be expanded immediately or kept at or below its post-vent temperature in a dry atmosphere for subsequent expansion.

Method For Decaffeinating Coffee With A Supercritical Fluid

View page
US Patent:
49119419, Mar 27, 1990
Filed:
Aug 5, 1988
Appl. No.:
7/229380
Inventors:
Saul N. Katz - Monsey NY
Jean E. Spence - Bogota NJ
Michael J. O'Brien - Port Monmouth NJ
Ronald H. Skiff - Edison NJ
Gerald J. Vogel - Carrollton TX
Ravi Prasad - Midlothian VA
Assignee:
General Foods Corporation - White Plains NY
International Classification:
A23F 520
US Classification:
426427
Abstract:
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.

US Patent:
52663426, Nov 30, 1993
Filed:
Jun 1, 1990
Appl. No.:
7/532160
Inventors:
Jean E. Spence - Bogota NJ
Saul N. Katz - Monsey NY
Gerald J. Vogel - Carrollton TX
Ravi Prasad - Midlothian VA
Assignee:
Kraft General Foods, Inc. - Northfield IL
International Classification:
A23F 522
US Classification:
426422
Abstract:
An improved method for extracting caffeine from a coffee material, preferably raw coffee solids, with an extractant comprising supercritical carbon dioxide. Caffeine is continuously absorbed from the extractant with an aqueous wash solution in an absorber. This wash solution is continuously treated by reverse osmosis to form a caffeine-containing retentate stream and a permeate stream containing dissolved solids but substantially no caffeine. The permeate stream is recycled and used as wash water in the absorber or is used to prehydrate solid coffee materials, or both. The permeate stream comprises acidic dissolved solids.

Caffeine Recovery From Supercritical Carbon Dioxide

View page
US Patent:
49963171, Feb 26, 1991
Filed:
Aug 5, 1988
Appl. No.:
7/229369
Inventors:
Michael J. O'Brien - Port Monmouth NJ
Jean E. Spence - Bogota NJ
Ronald H. Skiff - Edison NJ
Gerald J. Vogel - Carrollton TX
Ravi Prasad - Midlothian VA
Assignee:
Kraft General Foods, Inc. - Glenview IL
International Classification:
A23F 518
US Classification:
544274
Abstract:
A process and apparatus for caffeine recovery from supercritical carbon dioxide is disclosed. The process involves countercurrent extraction of caffeine from supercritical carbon dioxide with water at pressures in excess of 1,000 p. s. i. in an unpacked extraction column. The apparatus includes an unpacked extraction vessel having a distributor therein for distributing water throughout substantially the entire cross-sectional area of the vessel.

Process And Apparatus For The Semicontinuous Extraction Of Nicotine From Tobacco

View page
US Patent:
54977924, Mar 12, 1996
Filed:
Nov 19, 1987
Appl. No.:
7/122760
Inventors:
Ravi Prasad - Midlothian VA
Harvey J. Grubbs - Mechanicsville VA
Assignee:
Philip Morris Incorporated - New York NY
International Classification:
A24B 1524
US Classification:
131297
Abstract:
A process is provided for the improved removal of nicotine from tobacco. An essentially nicotine-free solvent in the supercritical or liquid state is fed into a first end of an extraction flow system containing tobacco and a nicotine-rich solvent is discharged from a second end of the extraction flow system. Periodically a portion of extracted tobacco is discharged from the first end of the extraction system while simultaneously a portion of an unextracted tobacco is charged to the second end of the extraction system. Nicotine is then entrapped in an entrapment material or otherwise removed from the solvent and solvent is recycled through the extraction flow system. Various materials are provided as entrapment materials. Among the entrapment materials provided are aqueous solutions containing absorbent selected from various acids and salts. Among the acids and salts provided as entrapment materials are sulfuric acid, phosphoric acid, nitric acid, tartaric acid, citric acid, malic acid, lactic acid, malonic acid, succinic acid, acetic acid, glutamic acid and monopotassium citrate.

Process For Removal Of Basic Materials

View page
US Patent:
50185403, May 28, 1991
Filed:
Nov 19, 1987
Appl. No.:
7/122761
Inventors:
Harvey J. Grubbs - Mechanicsville VA
Ravi Prasad - Midlothian VA
Tony M. Howell - Midlothian VA
Assignee:
Philip Morris Incorporated - New York NY
International Classification:
A24B 1524
A24B 1526
US Classification:
131297
Abstract:
A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco without materially affecting the content of the other components of the tobacco. Tobacco is traversed with a solvent at high pressure and in a physical state which is either a liquid at a pressure of from about 500-300 atmospheres or a supercritical fluid wherein nicotine and the other components dissolve in the solvent. As the single means of removing substances from the solvent, the solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine. The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine. In addition, the tobacco may be pretreated with a chemical base which does not substantially react with the tobacco components under ambient conditions and which are not necessarily affected by the process conditions but are nonetheless effective in increasing the amount of nicotine which can be extracted by the process of this invention. Pretreatment of the tobacco with a chemical base neutralizes nicotine salts and permits the extraction process to be carried out under milder conditions.
