WITHOUT BLEEDING OFF VAPORS GENERATED WITHIN THE CONTAINER, RETAINING THE BEANS WITHIN THE CONTAINER UNTIL ROASTED WITH A RESULTANT INCREASE IN PRESSURE IN THE CONTAINER TO WITHIN THE RANGE OF 50-350 POUNDS PER SQUARE INCH, OPENING THE CONTAINER AND DISCHARGING THE PRESSURIZED CONTENTS THEREOF DIRECTLY INTO A LOW PRESSURE SEALED RECOVERY CONTAINER OF LARGER CAPACITY THAN THE ROASTING CONTAINER WITH RESULTANT POPPING OF THE ROASTED BEANS TO PRODUCE A POROUS BEAN WITH THE ESCAPE OF MOISTURE VAPORS THEREFROM, MAINTAINING THE RECOVERY CONTAINER AT A TEMPERATURE BELOW 100*F. WITH CORRESPONDING CONDENSATION OF RELEASED VAPORS, CHURNING THE CONTENTS THEREOF TO BRING THE POPPED POROUS BEANS INTO CONTACT WITH THE BOUNDARIES OF THE CONTAINER UNTIL THE POPPED POROUS BEANS HAVE ABSORBED THE MOISTURE AND VAPORS CONDENSED ON THE BOUNDARIES, AND THEN OPENING THE RECOVERY CONTAINER AND REMOVING AND PACKING THE POPPED POROUS COFFEE BEANS.
