Claim 1
Independent Claim
197 words
IN A METHOD OF MAKING CHEDDAR CHEESE COMPRISING THE STEPS OF INOCULATING PASTEURIZED MILK WITH A CULTURE OF A LACTIC ACID-PRODUCING STARTER, RIPENING THE INOCULATED MILK WITH RENNENT TO COAGULATE THE MILK, CUTTING THE COAGULATED CURD AND HEATING THE CURD AND WHEY, THAT IMPROVEMENT WHICH COMPRISES SEPARATING FREE WHEY FROM THE CURD, DELIVERING THE SEPARATED CURD TO A CONFINED SPACE, DRAINING WHEY FROM THE INTERIOR OF THE CURD MASS AT A PLURALITY OF SPACED LOCATIONS THROUGHOUT THE AREA OF THE CURD MASS IN SAID CONFINED SPACE TO FORM A BLOCK OF THE CURD, PARTIALLY DIVIDING THE BLOCK OF CURD IN THE CONFINED SPACE, SUBJECTING THE CURD AT ONE PARTIALLY DIVIDED AREA OF THE BLOCK OF INTERNAL PRESSURE SUFFICIENT TO CAUSE A DISPLACEMENT OF A PORTION OF THE CURD MASS INTO THE REMAINDER OF THE MASS, SAID SIMULTANEOUS APPLICATION OF PRESSURE TO AND MOVEMENT OF THE CURD MASS ACCELERATING THE REMOVAL OF WHEY WHILE MAINTAINING PRESSURE ON THE CURD TO MAT THE CURD AND MOVE ANY POCKETS OF FREE WHEY TO A LOCATION WHERE IT CAN DRAIN, AND THEREAFTER PERMITTING THE BLOCK OF MATTED CURD TO SET FOR A PERIOD OF TIME TO DEVELOP THE ACID CONTENT THEREOF.

Claim 3
Dependent Claim
184 words
A CHEESE MAKING APPARATUS COMPRISING A VESSEL HAVING BOTTOM AND SIDE WALKS AND AN OPEN TOP AND FORMING A CHAMBER THEREIN, A PLURALITY OF PERFORATED DRAIN TUBES, MEANS FOR MOUNTING SAID TUBES FOR MOVEMENT INTO SAID VESSEL THROUGH THE OPEN TOP TO POSITION THE TUBES IN SPACED RELATION IN THE VESSEL, MEANS FOR DELIVERING A MASS OF CURDS AND WHEY INTO THE VESSEL AND AROUND SAID DRAIN TUBES, MEANS FOR PRODUCING A PARTIAL VACUUM IN SAID PERFORATED TUBES TO WITHDRAW WHEY FROM THE CURD MASS, AND A MECHANICAL CHEDDARING MECHANISM IN THE VESSEL COMPRISING A BLADE MOUNTED TO MOVE PARALLEL TO ONE WALL OF THE VESSEL, A PLUNGER BETWEEN THE BLADE AND WALL AND MEANS FOR OPERATING SAID BLADE AND PLUNGER ALTERNATELY TO SEGREGATE A PORTION OF THE CURD FROM THE REMAINDER OF THE CURD MASS AND PROVIDE AN OPENING THEREBETWEEN, FORCE THE SEGREGATED PORTION OF CURD INTO THE REMAINDER OF THE MASS THROUGH THE OPENING THEREBETWEEN AND THEN WITHDRAW BOTH THE BLADE AND PLUNGER TO PERMIT THE CURD MASS TO FLOW INTO THE SPACE FOR REPEATED MECHANICAL CHEDDARING BY THE BLADE AND PLUNGER.
