Title: Improvements in or relating to concentrated coffee extracts
IPC: A23F5/26
Filed: 1949-01-25
Abstract: 658,806. Coffee. AMERICAN HOME FOODS, Inc. Jan. 25, 1949, No. 2008. [Class 129] Aqueous extract of coffee is prepared by passing hot water through a number of percolators containing ground roasted coffee in a series of progressively less exhausted stages of extraction in the direction of travel of the water, the initial stages being at a temperature of 125‹-150‹C and the final stages being at about 15y-20‹C. Cold water delivered by a variable-delivery pump 8 is heated in a heat-exchanger 9a to between 125‹ and 150‹C and passed through a percolator 1a containing ground roasted coffee retained between screens 2a, 2b. The process is repeated in percolators 1b, 1c, the temperature being maintained by heat-exchangers 9b, 9c. In an intermediate section comprising percolators 1p, 1q, 1r, the temperature is allowed to fall gradually to below 50‹C, say about 40‹C. but not lower than 25‹C. In the final section, comprising percolators 1y, 1z, the temperature is maintained at below room temperature by heat-exchangers 17. The process is worked in counter-current fashion, each percolator coming into operation at the end of the series and progressively changing its station until it reaches the beginning, after which it is disconnected for recharging. Each percolator is associated with a percolator (not shown in the intermediate section) provided with both hot and cold water supplies so that the appropriate temperature can be maintained. Each percolator is charged through a manhole 5 from a hopper 4 which may be movable so that it can be brought over any desired percolator. After the air in a freshly-charged percolator has been expelled by the rising liquid, a valve in an air vent 21 is closed. There may be 12-16 percolators, with 4-7 in the hot section, 5-8 in the intermediate section, and 2-4 in the cold section. The extract may be dried to a powder, as by spray drying.

Abstract: 548,280. Caustic soda; soap; natural resins. BAKER, A., SALE, G. S., and SALE, C. V. (trading as SALE & CO.). Feb. 28, 1941, No.2725. [Classes 1 (ii), 91 and 95] [Also in Group IV] The liquor resulting from the boiling of cellulosic material in a caustic soda solution is trated with carbon dioxide or alumina in such proportion that precipitation of organic matter takes place and sodium bicarbonate or sodium aluminate is formed. The sodium salt is subsequently converted into caustic soda. When using carbon dioxide, the liquor is saturated with the gas, e.g. 11 pounds of carbon dioxide to each 10 pounds of caustic soda. The organic matter is precipitated without concentration of the liquor and it is separated, e.g. by filtration or centrifuging. The resulting sodium bicarbonate liquor is converted into a caustic soda solution; e.g. by treatment with lime. If alumina is used as precipitating agent, it is intimately mixed in moist freshly precipitated form with the liquor, e.g. 15 pounds calculated as dry aluminium oxide for each 10 pounds of caustic soda. Resins are separated and sodium aluminate remains in the solution. This may readily be converted into caustic soda. Before treating the liquor with carbon dioxide or alumina the free caustic soda may be converted into soap. The liquor may be heated with a saponifiable fat or fatty acid, e.g. 35 pounds of stearic acid for each 10 pounds of caustic soda, to form a soap which separates as a solid on cooling. The remaining liquid containing sodium compounds of resins is then treated with carbon dioxide or alumina to precipitate resins. The cellulosic material may be linseed straw or a hard wood. The Provisional Specification refers also to the use of other weakly acidic or amphoteric substances as precipitants instead of carbon dioxide or alumina.
