85 DEG C of thermokalite carries out second alkali process, and used thermokalite discharge filter, continues 360s during by first time alkali process.
S113 thermokalite circular treatments：With mutually synthermal and concentration toward addition in filter with step S112 identicals flow
Thermokalite, thermokalite circular treatment, duration 1800s are carried out to regenerative filter aid filtering layer.
Wherein, thermokalite circular treatment is specially：The outlet valve and recovery valve of thermokalite tank are opened, first to being passed through in filter
Thermokalite, carries out thermokalite and washes away to filter, and circulation alkali liquor is recovered in thermokalite tank further through filter outlet at bottom pipe then,
So move in circles as thermokalite circular treatment.
Wherein, the step be regenerative filter aid filtering layer alkali regenerative process in a most important step, using alkali process, can
Eluted with the beer " biological impurities " and the polyphenol substance of absorption that will effectively be attached on regenerative filter aid filtering layer.For
Guarantee cleaning performance, the present invention to the regenerative filter aid filtering layer after beer filtration carries out alkali process using substep；Use first
Thermokalite carries out first time alkali process, i.e. prerinse to regenerative filter aid, and thermokalite at this moment is polluted by beer biological impurities, therefore
Need to drain；Then a hot alkali treatment is carried out again, i.e., second alkali process are further cleaned and by used by first time alkali process
Alkali lye discharges filter, is the most cleverly that the time of substep alkali process sets after a thermokalite circular treatment is carried out again after 360s
Put, if in first time hot alkali treatment overlong time, easily causing alkali lye serious waste, if the time is too short, cause again after
Continue second alkali process overlong time, it is most important that, the beer remained in the alkali lye used by second alkali process can be caused to give birth to
Thing impurity, polyphenol impurity are excessive, cause the thermokalite used by second alkali process to realize recycling after reclaiming.It is of the invention
Substep alkali process and creativeness are provided with the step-by-step processing time, on the basis of regeneration effect is ensured, waste alkali lye and reach
