Appeal No. 2003-0729
Application 08/914,346
conveying the wort from the lauter tun at an outflow rate, and
the lauter tun having an outflow regulator adapted to control the
wort outflow, comprising the steps of:
measuring a first wort outflow rate;
selecting a predetermined second and increased outflow rate
different from the first;
selecting a predetermined time interval for reaching the
second outflow rate;
determining the incremental outflow rate increase per unit
time corresponding to such change in outflow rate in such time
interval; and
using a value corresponding to the incremental outflow rate
increase per unit of time as a set point for the control means
for controlling the wort outflow.
20. A device for brewing and controlling a wort outflow from
the brewing device, comprising:
a lauter tun;
a discharge pipe connected to said lauter tun for carrying
said wort away from the lauter tun;
a flow meter connected thereto, the flow meter being
positioned to measure wort outflow;
an outflow regulator coupled thereto for controlling the
flow of wort from the lauter tun through the discharge pipe; and
a discharge control connected to the outflow regulator and
to receive the outflow values from the flow meter, the discharge
control being configured to provide control signals for
controlling the outflow using a value corresponding to an
incremental outflow rate per unit of time as a set point, such
incremental outflow rated [sic, rate] based on a first wort
outflow rate measured by the flow meter, a selected predetermined
second and increased outflow rate different from the first, and a
selected predetermined interval for reaching the second outflow
rate.
