Pharma Peeler Dryer
DRYER
 The
centrifuge system is connected with the conical
dryer, the wet cake from the centrifuge machine
is dropped directly into the dryer in a totally
enclosed condition. This arrangement ensures that
there is no product contamination; and manual handling
of the product is completely eliminated. The system
is ideally suitable for toxic and hygroscopic products,
sterile and USFD approved plants.
MAIN PROCESS VESSEL (CONE)
The dryer main process vessel is conical in shape,
with the inside wall being a polished surface. The
outside of the shell is provided with heating the
surface. Over this is an insulation jacket for heating
the surface. Over this is an insulation jacket that
ensures that the heat transfer is only in one direction,
i.e. only on main shell.
DRYER TOP COVER
The dryer top cover is hinged type openable cover
and provided with insulation jacket. The cover is
provided with light and sight glass flanges, Product
input (Feed) nozzle having flanged connection ,
vacuum filter assembly and pad flange for bearing
housing agitator assembly. The inside of the cover
is polished, suitable for cGMP standards. The cover
is provided with hinge plates and pin with counter
balance spring unit for the ease of opening manually,
without any mechanized device.
 AGITATOR
& BEARING HOUSING ASSEMBLY
Dryer is provided with an agitator assembly consisting
of shaft and spiral blades. The spiral blades are
provided throughout the process area of the dryer.
The spiral blades are so designed that during rotation
it has a minimum clearance between the bladdes and
vessel wall. The rotational action of the agitator
picks up wet powder from center and splashes on
the sidewall of the vessel, which is heated by the
heating media. In this manner, the product is dried.
The shaft is supported by taper roller sealed bearings.
The shaft entry inside the dryer vessel is provided
with cartridge type mechanical seal assembly for
leak proof sealing.
FILTER ASSEMBLY:
Filter assembly is provided on top of the dryer
cover. During drying operation, vacuum is applied
inside the vessel through this assembly. The vacuum
assembly is provided with specially designed filter
bag holding cage, so that, when vacuum is applied
the dried particulate do enter in to vacuum stream
and product loss is completely avoided. The bag
assembly is a quick openable design, thus after
every batch the filter bag can be replaced or removed
for cleaning purpose. In this manner, it fulfills
the cGMP and USFDA requirements of batch contamination
or mix up.
DRIVE:
The dryer agitator assembly is driven by electric
motor, mounted on the top of the shaft. The motor
is driven by AC inverter variable speed drive to
vary the speed of the agitator as per the process
requirements.
PRODUCT OUT-PUT FLANGE
& OTHER ASSEMBLIES:
The dryer bottom flange is provided with product
out-put flange to fix product discharge valve. The
valve can be fitted between flanges. The out-put
flange is provided with nitrogen purge nozzles to
flush the dried product after discharge.
SEALS AND GASKETS:
All the process contact gaskets and ‘O’
rings for the centrifuge and dryer are PTFE encapsulated
viton or silicon rubber to give longer sending sealing
life. Also, these ensure zero- contamination, as
PTFE withstands almost all material and higher temperatures.
