Little incinerator available

Volume reduction of the waste after processing: by 60-80percent through complete waste dehydration such as fluid

content of the waste

All actions after loading for sterilization, fragmentation of product is to be occurred in the same chamber/vessel

Pre or Post-air evacuation should not be necessary or used

Exhaust air quality: Does not need any venting for odor management

Operating System: Fully automatic with manual over-ride. (On board PLC capable of generating written report with

cycle period, cumulated time at >121◦C

The option should be there for Web connectivity by phone, cable or

Boiler: should not need pre-heated water

Electrical requirements: 220Vac, 1ph or 400vac 3ph to suit customer needs

Noise level at complete operation: <80 dB

Working Principle of the chip

The chip should utilize steam technology together with a mechanical fragment (grinder) to sterilize

medical waste, thus making the residual waste safe for disposal in landfills.

The sterilization vessel MUST be a double walled (jacketed) cylindrical vessel.

Pre-shredding of infectious waste must not be accepted, the fragmentation must occur safely within the scaled vessel


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 produce an unrecognizable size of the waste product

The fragmenting are have to rotate to agitated continuously through the heating and sterilization cycle to ensure

that the fragmented & agitated wastes (such as sharps and liquids) are exposed evenly to sterilization temperature

and pressure.

Steam heating ought to be applied to the jacket only, although the agitated waste absorbs the heat from the jacket and makes

its steam from its moisture content.

Should not desire for special autoclave bags- simple bag or box ought to be workable

MUST not need for pre-treatment of the waste.

Liquids and gases MUST remain locked within the vessel until sterilization is complete-nothing ought to be vacuumed or

pumped out in its infected state.

Jacket steam heating to dehydrate the waste completely regardless of its original water content.

All the hot condensate in the jacket is recycled, making the chip quite economical to operate

All particles of the waste should achieve a high level of sterilization and not only”disinfection” because of the

constant agitation.

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 is intended

Over-loading or loading too closely should not be an problem with this procedure, and hence no requirement of the special

operator skill.

ii)Heat –upward and fragmentation

After loading, the vessel door is to be closed, along with the outer jacket of the vessel is to be mechanically filled

with high temperature steam, which should act as the major heating medium for heating the waste

During this heating cycle, the shaft and mixing arms ought to bend continuously, causing the waste to become fragmented

and always tumbled against the hot vessel walls.

now, the waste is broken up into little fragments, and all material heats up rapidly, being evenly and

thoroughly subjected to the hot inner surfaces. The moisture content of the waste will turn in to steam, along with the vessel

will begin to pressurize.

Initially, no steam will be injected into the waste. If there insufficient moisture in the waste to pressurize the

vessel, a little bit of steam is to be automatically inserted until the desired pressure is reached.

At the end of the period, the correct sterilization temperature and ought to be reached, and the sterilization interval

should begin.

iii)Sterilization interval

The quantity of steam fed into the outer jacket is to be controlled to maintain the desired temperature & pressure of the

inner vessel.

The mixing arms (grinder)  MUST continue to rotate during this cycle to make sure even sterilization pressure and

fever for many wastes.

The treatment period should be either 15 minutes at 132◦C OR 30 minutes at 121◦C  to reach level 6log10 sterilization

The extreme subjugation of the waste to elevated temperature and pressure moisture in a dynamic environment should also

cause the waste to hydrolyze, that is a quick decomposition of organic material.


Following the treatment period, the steam into the jacket should remain on, and the internal vessel would be to

be vented through a condenser, and de-pressurized. Therefore, the waste loses its water content

by means of a combination of heat input in the jacket and trapping of water because of



Further dehydration will be achieved by keeping heat input and mixing-almost total dryness ought to be achieved.

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



Further dehydration is to be achieved by maintaining heat input and mixing-almost total dryness should be achieved.
