The
sterilized powder is stored in two
powder hopper agitated by pair of
mechanical agitators for maintaining
consistency and uniform bulk density,
Each powder wheel having eight ports
in Two Rows rotates at the pre determined
speed below the powder hopper with
practically no clearance. Powder wheel
consist of Piston in each port and
behind the powder wheel vacuum plate
is provided there is no clearance
between powder wheel and vacuum plate
due to back spring pressure. Precise
volume of powder is sucked in to the
port of powder wheel during vacuum
according to the piston length different
fill size can be achieved. The excess
powder is doctored off by a doctor
blade, Now doctor blades can be adjusted
from outside also without removing
powder hopper. When powder wheel indexes
further and remain in the port due
to the vacuum till it reaches just
vertically above the vial. The time
dose of Compressed air, sterilized
low pressure air or Nitrogen Gas sequentially
flushes out powder from the port of
powder wheel in to the vial one by
one. It is a double wheel Double track
machine, Machine will fill first two
row of vial in double track in preliminary
filling station for ‘X”
product and then vial will be separated
on conveyor by vial separator and
vial moves towards Secondary filling
station for filling of “Y”
product, again filled vial will be
separated by another pair of vial
separator on conveyor are gradually
moved and submerged in Single Row
for Rubber Stoppering Operation. |
