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

* Noise level at full operation: < 80 dB

Working Principle of the processor:

*  The processor should utilize steam technology in conjunction With a mechanical fragmentor (grinder) to sterilize

medical waste, thereby  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 safety inside 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 inside the vessel to produce all unrecognizable size of the waste product.

* The Fragmenting are must rotate to agitate waste continuously throughout the heating and sterilization cycle to

ensure that the fragmented q agitated wastes (including sharps and liquids) are exposed evenly to sterilization

temperature and pressure.

* Steam heat should be applied to the jacket only, while the agitated waste absorbs the heat from the jacket and makes

its own steam from its moisture content.

* Should not need for special autoclave bags — simple bag or box should be workable

* MUST not need for hi c-treatment of the waste.

* Liquids and gases MUST remain locked inside the vessel until sterilization is complete – nothing should be vacuumed

or pumped out in its infected state.

* Jacket steals heat to dehydrate the waste completely regardless of its original water content.

* All the hot condensate from the jacket is recycled, making the processor very economical to operate

The incinerator plant shall incorporate a control panel for its operation. On the control panel we shall have a visual

display of the chamber temperatures. This visual display must control and monitor the incinerator and his performance.

Capacity of destruction in weight shall be 60 Kg/h.

It should be able to operate not less than 10 hours/day

This incinerator must be able to destruct all combustible wastes produced by hospitals, private clinics, laboratories,

institutes, etc…

Design Specification : Types A, B, C, D, and E of medical waste

Supply, installation & testing DUCTED SPLIT UNITS at waste store with sufficient capacity to maintain the internal

temperature at 14 degrees Celsius in summers and winters

All particles of the waste should achieve a high level of sterilization and not just “disinfection” due to the

continuous agitations

Description of the Treatment Cycle of the processor

1. i) Loading

* The waste has to be loaded by dropping bagged and or boxed waste into the open loading door on the vessel.

* The loading door should be mounted at an angle on time top side, of the vessel with suitably sized to accommodate the

infectious wastes for which it is intended

* Over-loading or loading too tightly should not be an issue with this process, and hence no need of the special

operator skill.

1. ii) Heat-up and fragmentation

* After loading, the vessel door is to be closed, and the outer jacket of the vessel is to be automatically filled with

high temperature steam, which should act as the main heating medium for heating the waste.

* During this heating cycle, the shall and mixing arms should rotate continuously, causing the waste to be fragmented

and continuously tumbled against the hot vessel walls.

* At this point, the waste is broken up into small fragments, and all material heats up rapidly, being evenly and

thoroughly exposed to the hot inner surfaces. The moisture content of the Waste will turn in to steam, and the vessel

will start to pressurize.

* Initially, no steam will be injected into the waste. If there is not enough moisture in 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 this period, the correct sterilization temperature and pressure should be reached, and the

sterilization period should start.

iii) Sterilization period

* The amount of steam fed to the outer jacket is to be regulated to maintain the desired temperature & pressure of the

inner vessel,

* 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 either15 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.

1. 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.

1. v) Dc-hydration

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

1. vi) Unloading

* Finally, steam to the jacket should shut off, the unloading door is to be opened

* Then the shaft and mixing arms are reversed to act as unloading mechanism and should scoop the waste fragments out of

the unloading door, onto a conveyor belt or directly into a waste container.

* The vessel should now be ready for another treatment cycle, having retained most of its heat for the treatment of the

next batch.
