Claim 1
Independent Claim
93 words
A METHOD OF REMOVING UNDESIRABLE SOLIDS FROM COFFEE EXTRACT COMPRISING THE STEPS OF OBTAINING COFFEE EXTRACT, FILTERING SAID EXTRACT IN A MEDIUM DUTY FILTER TO REMOVE VISIBLE SEDIMENT AND ORGANIC MATERIAL AND TO HIGHLY REDUCE MICROSCOPIC INSOLUBLES, REDUCING THE TEMPERATURE OF THE FILTERED EXTRACT, FREEZE CONCENTRATION EXTRACT TO BETWEEN 50*-80*F ING SAID CONCENTRATED EXTRACT TO BETWEEN 50*-80*F AND CLARIFYING THE HEATED CONCENTRATED EXTRACT IN A DESLUDGING-TYPE CENTRIFUGE EFFECTIVE TO REMOVE INSOLUBLES WHICH IF NOT REMOVED PRIOR TO DRYING CAUSE UNDESIRABLE BLACK SPOTS TO APPEAR AS FOREIGN MATTER IN A RECONSTITUTED CUP OF COFFEE.
Claim 2
Independent Claim
93 words
A METHOD OF REMOVING UNDESIRABLE SOLIDS FROM COFFEE EXTRACT COMPRISING THE STEPS OF OBTAINING COFFEE EXTRACT, FILTERING SAID EXTRACT IN A MEDIUM DUTY FILTER TO REMOVE VISIBLE SEDIMENT AND ORGANIC MATERIAL AND TO HIGHLY REDUCE MICROSCOPIC INSOLUBLES, REDUCING THE TEMPERATURE OF THE FILTERED EXTRACT, FREEZE CONCENTRATION EXTRACT TO BETWEEN 50*-80*F ING SAID CONCENTRATED EXTRACT TO BETWEEN 50*-80*F AND CLARIFYING THE HEATED CONCENTRATED EXTRACT IN A DESLUDGING-TYPE CENTRIFUGE EFFECTIVE TO REMOVE INSOLUBLES WHICH IF NOT REMOVED PRIOR TO DRYING CAUSE UNDESIRABLE BLACK SPOTS TO APPEAR AS FOREIGN MATTER IN A RECONSTITUTED CUP OF COFFEE.
