  • Patent number: 5322703
    Abstract: Green coffee beans are dried prior to roasting to a moisture content of from 0.5 to 7%. The drying is conducted at from 70.degree. to 325.degree. F. (21.degree. to 163.degree. C.) for from 1 minute to 24 hours. The dried green beans are fast roasted to a Hunter L-color of from 10-16. The dried roasted beans are blended with non-dried coffee beans roasted to a Hunter L-color of from 17-24 and having a moisture content before roasting of greater than about 7%. The blend contains from 1-50% of the dried dark roasted beans and from 50-99% of the non-dried roasted beans. The blend has a surprisingly high yield.

  • Patent number: 5227188
    Abstract: Roasted coffee granules are admixed with roasted coffee non-granules in critical weight ratios. The smaller coffee non-granules include flaked coffee, flaked coffee fines, ground coffee fines, and coffee agglomerates. The larger coffee granules include roast and ground coffee. The coffee granules and coffee non-granules are densified to between 0.41 to 0.56 grams/cc. The compact coffee has the flowability, flavor, aroma and strength of roast and ground coffee. At equal volumes, the compact coffee results in more brewed coffee than conventional roast and ground coffee.

  • Patent number: 5160757
    Abstract: This invention relates to an improved process for preparing reduced density roast coffee beans. The improved process comprises predrying green coffee beans to a moisture content of from about 0.5% to about 10% by weight, fast roasting the beans, and cooling the roasted beans. The resulting roasted beans have a Hunter L-color of from about 14 to about 25, a Hunter .DELTA.L-value is less than about 1.2 and a whole roast tamped bulk density of from about 0.28 to about 0.38 g/cc. The resulting roast coffee beans are more uniformly roasted than traditional reduced density coffee beans.

  • Patent number: 4985271
    Abstract: The invention is a method for treating coffee beans to make a better-tasting and improved aroma coffee. Green coffee beans are first partially roasted to a Hunter a-color between about 3 and about 9, under roasting conditions sufficient to increase the Hunter a-color of the beans by at least about 1.5 a-color units during the partial roasting step. The partially roasted beans are then treated with either an alkaline solution comprising water and a foodgrade base, or a coffee bean extract solution comprising water and from about 1% to about 12% coffee solids. Preferably, the partially roasted beans are treated by soaking them in the solution at a temperature between about 65.degree. F. (18.degree. C.) and about 120.degree. F. (49.degree. C.) for a time between about 2 hours and about 24 hours.

  • Patent number: 4637935
    Abstract: The present invention is a process for making a reduced density roast and ground coffee product comprising the steps of: (a) cracking roasted coffee beans to a size such that about 40% to about 80% are retained in a 6-mesh screen (3.36 mm, 0.132 in.); then (b) normalizing the cracked beans; and then (c) grinding the cracked and normalized beans. The roast and ground coffee product produced by the combination of the three steps has a density between about 0.24 g/cc and about 0.41 g/cc.The reduced density roast and ground coffee product has an acceptable non-chaffy appearance. Problems associated with the use of air removal and screening are avoided.
