Abstract
Abstract Roast and ground coffee in the form of high-sheen flakes and having improved extractability is disclosed. A process for preparing flaked roast and ground coffee of high sheen and improved extractability by passing roast and ground coffee through a roll mill operating at differential speeds and temperatures is also disclosed. The process comprises: passing roast and ground coffee through a roll mill wherein a first roll has a peripheral surface speed of 30 ft./min. to 850 ft./min. and a surface temperature of from 0° to 140° F and a second roll has a peripheral surface speed corresponding to from 2 to 8 times that of the first roll and a surface temperature of from 150° to 300° F.; and removing from said roll mill roast and ground flakes of high sheen and extractability.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A roast and ground coffee composition comprising from 10 to 80% by weight of the composition of roast and ground coffee in the form of flakes of high sheen and extractability, said roasted and ground flaked having a flake thickness of between 0.008 and 0.025 in. and having a reflectance value of at least 35 reflectance units, said reflectance units representing reflectance by coffee flakes of light from 0.88 helium/neon gas laser beam of 6328 Angstrom wavelength, calibrated against reflectance values of 2 and 89 units, respectively, for the Federal Bureau of Standards Paint Chips 15042 and 11670; and from 20 to 90% of non-flaked roast and ground coffee.
Claim 2
Dependent Claim
109 words
A roast and ground coffee composition comprising from 10 to 80% by weight of the composition of roast and ground coffee in the form of flakes of high sheen and extractability, said roasted and ground flaked having a flake thickness of between 0.008 and 0.025 in. and having a reflectance value of at least 35 reflectance units, said reflectance units representing reflectance by coffee flakes of light from 0.88 helium/neon gas laser beam of 6328 Angstrom wavelength, calibrated against reflectance values of 2 and 89 units, respectively, for the Federal Bureau of Standards Paint Chips 15042 and 11670; and from 20 to 90% of non-flaked roast and ground coffee.
Claim 3
Dependent Claim
34 words
Roast and ground coffee according to claim 1 wherein the roast and ground coffee flakes comprise from 25 to 60% by weight and the non-flaked roast and ground coffee comprises from 40 to 75%.
Claim 4
Dependent Claim
28 words
Roast and ground coffee according to claim 2 wherein the roast and ground coffee flakes are characterized by a reflectance value of from 40 to 60 reflectance units.
Claim 5
Dependent Claim
98 words
A process for preparing roast and ground coffee flakes of high sheen and extractability which comprises: passing roast and ground coffee through a roll mill having a first roll operating at a peripheral surface speed of from 30 to 850 feet per minute and at a surface temperature of from 0° to 140° F and having a second roll operating at a peripheral surface speed of from 2 to 8 times that of the first roll and a surface temperature of from 150° to 300° F; and removing from said roll mill said roast and ground coffee flakes.
Claim 6
Dependent Claim
98 words
A process for preparing roast and ground coffee flakes of high sheen and extractability which comprises: passing roast and ground coffee through a roll mill having a first roll operating at a peripheral surface speed of from 30 to 850 feet per minute and at a surface temperature of from 0° to 140° F and having a second roll operating at a peripheral surface speed of from 2 to 8 times that of the first roll and a surface temperature of from 150° to 300° F; and removing from said roll mill said roast and ground coffee flakes.
Claim 7
Dependent Claim
25 words
The process of claim 4 wherein said second roll has a peripheral surface speed of from 3 to 5 times that of said first roll.
Claim 8
Dependent Claim
32 words
The process of claim 4 wherein said first roll has a peripheral surface speed of from 250 to 650 feet per minute and a surface temperature of from 50° to 100° F.
Claim 9
Dependent Claim
35 words
The process of claim 6 wherein said second roll has a peripheral surface speed of from 3 to 5 times that of said first roll and a surface temperature of from 180° to 220° F.
Claim 10
Dependent Claim
35 words
The process of claim 4 wherein said second roll has a peripheral surface speed of from 3 to 5 times that of said first roll and a surface temperature of from 180° to 220° F.
Claim 11
Dependent Claim
23 words
The process of claim 4 wherein the roll mill has a roll pressure of from 1500 to 3500 pounds per inch of nip.
Claim 12
Dependent Claim
19 words
The process of claim 9 wherein the roll pressure is from 2000 to 3000 pounds per inch of nip.
