Rubber Bung Processor Cum Steriliser
Processing of bungs
(electrometric closures for drug containers) is of high concern since they
play a significant role in the quality and life of the final product.
The need for correct processing technology is even more important
considering the complexities in the compounding of the rubber used for the
closures and the non-compliance to GMP by the manufacturers of the
Considering the criticality of bung processing, our engineers at Neelam
Industries with over 20 years of varied technical experience developed a
unique 5 in 1 approach as against the conventional method of closure
PROCESS FOR BUNG WASHING PROGRAMS :
- Rotating carriage : We have designed the rotating carriage
that has a triangular cassette sections with perforated sides for
hooking the bungs.
- Sprinkling manifold : The machine is provided with sprinkling
manifold arrangement over the rotating carriage to enables uniform
sprinkling over the entire lot.
- Fluidisation manifold : For rigorous fluidization, the
Fluidization manifold causes turbulence in the water soaked bungs for
- Triple Punch Cleaning system is implemented to ensure through
cleaning and sterilization of the closures. This would comprise of the
three sub stages mentioned here. A fluidization system with sterile air
for mild turbulation of the closures.An overflow system for removing the
floating scum and dirt removed from the closures.A recirculation system
with filtration for eliminating the dirt released during the process.
This also helps in conserving the different process mediums thereby
controlling process cost.
- Facility to sample drain water automatically by the Online
Conductivity sensor to ensure Proper washing of the bung.
- Clean In Place system (CIP) : The BUNG PROCESSOR is fitted
with a Clean In Place (CIP) system for washing the chamber and the
rotating carriage to prevent the released dirt to be carried out from
one phase to subsequent phase. This is particularly important before the
start of the "Rinse with purified water" and "Sterilization"
- Drive System : Neelam Industries developed friction drives to
prevent direct metal to metal contact for superior process. Specially
developed plastic gears are used to ensures no particle generation
during the process and allows the absence of any lubrication.A special
non-lubricated mechanical seal is used for pressure and vaccum tight
operation of the driving system.
- Dual Operation : The BUNG PROCESSOR is designed for a unique
dual operation.To saves additional investment and space.
The Process of bung processing are loading, washing with detergent, D.M.
water&W.F.I.water rinsing ,siliconization , sterilization and drying.
The loaded bungs are washed with detergent solution via a fully automatic
detergent dozing system with online conductivity sensor to add the required
amount of Detergent in the sterilizer during the cycle.
The washed bungs are rinsed with deionized water and WFI water and the
quality of WFI water at outlet will be checked automatically to ensure the
proper washing of the bungs.
After cleaning closures are siliconized using a silicone emulsion or oil.
Siliconization of closures is necessary to prevent the release of
plasticizers and other compound added during the compounding of elastomeric
closures, to prevent any reaction between the closure and the medication
stored or to ensure smooth operation of the machines used for bunging.
In Sterilization the closures are sterilized with steam. A pre-vaccum
process is employed to ensure effective removal of air and penetration of
After sterilization the closures are dried using a vaccum drying process.
The drying efficiency is further improved by the continuous rotation of the
closures. Process ensures bone dry closures on unloading.
