Sterilization time: approx. 30 minutes at 121◦C/1.1 Tavern or approx 15 minutes at 132◦C/2.5 Tavern to reach 6log10
sterility
Fragmentation within the chamber: Heavy duty with maximum size of final product <20 cm.
Volume reduction of the waste after processing: by 60-80% through complete waste dehydration including liquid
content of this waste
All actions after loading for sterilization, fragmentation of merchandise is to be happened in the identical chamber/vessel
Pre or Post-air evacuation should not be necessary or used
Exhaust air quality: Does not need any venting for odor control
Operating System: Fully automatic with manual over-ride.
The sterilization vessel MUST be a double walled (jacketed) cylindrical vessel.
Pre-shredding of infectious waste should not be accepted, the fragmentation should occur safely within the scaled vessel
continuously.
The sterilization vessel/chamber must be fitted with a motor driven shaft to which a heavy duty grinder (fragmenting
arm) is attached within the vessel to make an unrecognizable size of this waste product
The fragmenting are must rotate to agitated continuously through the heating and sterilization cycle to guarantee
that the fragmented & sterile wastes (including sharps and liquids) are vulnerable evenly to sterilization temperature
and strain.
Steam heat ought to be applied to the coat only, while the agitated waste absorbs the heat from the coat and makes
its own steam from its moisture content.
Should not need for special autoclave bags- easy bag or box ought to be workable
MUST not need for pre-treatment of this waste.
Liquids and gases MUST stay locked within the vessel until sterilization is complete-nothing ought to be vacuumed or
pumped out in its infected state.
Jacket steam heat to dehydrate the waste completely no matter its original water content.
All the hot condensate from the coat is recycled, which makes the chip very economical to operate
All particles of this waste should achieve a high level of sterilization instead of just”disinfection” because of the
constant agitation.
Description of the Remedy Cycle of the chip
I)Loading
The waste has to be loaded by falling bagged and or boxed waste to the open loading door on the vessel.
The loading door ought to be mounted at an angle on the top side of the vessel with suitably sized to accommodate the
infectious wastes for which it’s intended
Over-loading or loading too tightly should not be an issue with this process, and hence no need of the special
operator ability.
ii)Heat –up and fragmentation
After loading, the vessel door is to be closed, and the outer coat of this vessel is to be automatically filled
with high temperature steam, which should act as the principal heating medium for heating the waste
in this heating cycle, the shaft and mixing arms ought to rotate continuously, causing the waste to be fragmented
and always tumbled from the hot vessel walls.
At this point, the waste is broken into small fragments, and all material heats up quickly, being evenly and
thoroughly exposed to the hot inner surfaces. The moisture content of the waste will turn into steam, and the vessel
will begin to pressurize. If there insufficient moisture from the waste to pressurize the
vessel, a small amount of steam is to be automatically added until the desired pressure is reached.
At the end of the period, the right sterilization temperature and should be reached, and the sterilization period
must begin.
iii)Sterilization interval
the total amount of steam fed to the outer coat is to be regulated to keep the desired temperature & pressure of this
inner vessel.
The mixing arms (grinder) MUST continue to rotate during this cycle to ensure sterilization pressure and
temperature for many wastes.
iv)De-pressurization
Following the treatment time, the steam to the coat should stay on, and the internal vessel is to
be vented through a condenser, and de-pressurized. Thus, the waste loses its water content
through a combination of heat input from the coat and flashing of water because of
depressurization.
v)De-hydration
Further dehydration is to be achieved by keeping heat input and mixing-almost complete dryness ought to be achieved.
The mixing arms (grinder) MUST continue to rotate throughout this cycle to ensure even sterilization pressure and
temperature for all wastes.
The treatment time should be either 15 minutes at 132◦C OR 30 minutes at 121◦C to achieve level 6log10 sterilization
The intense subjugation of the waste to high temperature and pressure moisture in a dynamic environment should also
cause the waste to hydrolyze, that is a rapid decomposition of organic material.
iv)De-pressurization
After the treatment time , the steam to the jacket should remain on, and the internal vessel is to
be vented through a condenser, and de-pressurized. Thus, the waste loses its water content
through a combination of heat input from the jacket and flashing of water due to
depressurization.
v)De-hydration
Further dehydration is to be achieved by maintaining heat input and mixing-almost total dryness should be achieved.
