The duplex vacuum
plodder is the machine which extrudes the final soap which suitable for
stamping. The extruder
screw of top noodle plodder takes the milled soap ribbons of soap from
hopper and presses the soap as it tries to
pass through noodle plate. There is a rotating knife which cuts the
noodles as
they come out of the noodle plate. The noodles fall in the vacuum
chamber.
The screw of the bottom screw binds the soap noodles under vacuum as
the soap
mass comes out under pressure from the mouth of the cone through the
die.
Extruder has a seamless pipe
SS-304 stainless steel. Aluminum alloy screw is rotating inside the
pipe. The pressing
action binds the soap under vacuum. The soap as it emerges from the
conical mouth of the plodder it is
cut into bars of suitable sizes. The pipe is jacketed to circulate
water in it. Mouth of
cone is jacketed and has facility to hold temperature sensor and
heater. After certain
temperature is attained it is maintained by thermostat mechanism which
assures that soap
bar emerges freely and has shiny appearance. If temperature is too high
soap surface will
be blistered and if the temperature is too low the soap surface will be
dull. The screw is
rotated by shaft revolving in pedestals. The pedestal has tapered
roller bearings which
take heavy axial and radial load. The shaft is driven by a gear box.
