The LED technology can be used
inside an industrial carafe...
...or in a commercial coffee
maker
The
most important aspect of the
light beam coffee maker is that
the optical monitor provides a
continuous readout of the
"freshness" of the brewed
coffee. As the brewed coffee
sits upon the warmer plate we
all know that it becomes "stale"
and, within an hour or so of
brewing, it no longer is so
tasty. The optical monitor
indicates this loss of freshness
and displays it on a ten LED
bargraph. Hence, freshly brewed
coffee has all ten LED's lit;
but within an hour, only 1 or 2
LED's remain lit, indicating the
degree of "staleness". We
believe this represents a
significant improvement in
brewing technology, allowing one
to tell at a glance when the
coffee is no longer palatable.
