Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
A method for aromatizing a mass or adsorbent coffee particulates with a carrier oil enriched with coffee aroma, said method comprising: (a) dividing a mass of coffee particulates into a bulk stream and a fraction stream; (b) forming the fraction stream of coffee particulates into at least one continuously moving ribbon of particulates; (c) injecting a carrier oil enriched with coffee-aroma into each continuously moving ribbon of particulates at a predetermined liquid to solids weight ratio; (d) blending the aroma enriched fraction stream into said bulk stream to form a uniform dispersion of aroma-enriched coffee particulates in said mass of coffee particulates.
Claim 2
Independent Claim
102 words
A method for aromatizing a mass or adsorbent coffee particulates with a carrier oil enriched with coffee aroma, said method comprising: (a) dividing a mass of coffee particulates into a bulk stream and a fraction stream; (b) forming the fraction stream of coffee particulates into at least one continuously moving ribbon of particulates; (c) injecting a carrier oil enriched with coffee-aroma into each continuously moving ribbon of particulates at a predetermined liquid to solids weight ratio; (d) blending the aroma enriched fraction stream into said bulk stream to form a uniform dispersion of aroma-enriched coffee particulates in said mass of coffee particulates.
Claim 3
Dependent Claim
23 words
The invention according to claim 16, wherein the ratio of fraction stream to bulk stream is 10% fraction stream to 90% bulk stream.
Claim 4
Dependent Claim
18 words
The invention according to claim 17, wherein the ratio of liquid to solids weight is 0.1% aroma-enriched liquid.
