Integrated Medical Waste Steam Sterilizer
The treatment executed by the Sinicmed integrated medical waste Steam Sterilizer with shredder is based on the sterilization principles using direct and saturated steam. This sterilization lead to the destruction of all the bacterial spores, virus and bacteriophage, mold spores, microorganisms, and maintains the inactivation of virus etc.
The autoclave adopts the processing technology of shredding first and then steam sterilization.
It is designed for small and medium-sized medical waste treatment centers, hospitals, infectious disease prevention institutions, customs, etc.
All the process is fully automatic and in a fully sealed chamber, thereby making medical waste treatment safer and more efficient. The operator has no contact with the medical waste during the process and the working environment is more friendly. The equipment not only fully meets the requirements of the "Medical Waste Management Regulations", but also meets the process requirements of the "Medical Waste High Temperature Steam Treatment Engineering Technical Specifications" and EU, WHO standards.
Type of material to be shredded and sterilized
Sharps, glass caps, syringes with needles included, bottles with liquid waste, pathological waste (upper and lower limbs), gauze, threads, gloves, cloth, catheters, serum hoses, hemodialysis filters, plastic filters, cotton, surgical waste, waste with high moisture levels (blood bags) and etc.
Features
Safety design
- Shredding and sterilization in one enclosed compact chamber. No contact with waste during process. Internal and integrated autoclave shredder, with dual-shaft motors, with a grinding system (dual-shaft blade) highly resistant to abrasion and temperatures, made of special alloy.
- The program has three levels of passwords. The operator's configurations require a password to restrict access to only administration in order to prevent improper modification of the programs by unauthorized users. Operators can only execute the start up cycle.
- The autoclave adopts interlock safety system which guarantee the door cannot be opened during the process, the cycle cannot start if the door doesn't be closed.
- It has emergency valve to eliminate steam from the chamber manually.
- Self-diagnosis of operation and fault record.
Simple operation
- Easy to use. One day training for operators. The autoclave and accessories are skid-mounted which is easy for installation.
- It has Siemens PLC and touch screen. Real-time data such as sterilization time, pressure, time and temperature can be displayed on the screen for easy viewing by operators.
- Operator can choose automatic dumper which is convenient for waste feed in.

(MWT-100&MWT-150 with automatic dumper)
Environmental friendly
1,The final product is a sterilized and shredded waste which can be disposed as a house hold waste.
2, It has bio-filter to guarantee the waste air is sterile.
3, Green technology; Environmentally friendly; No hazardous emissions(smoke, chemical release, radiation) . Allow on-site treatment.
4, After sterilization, the microbial Inactivation can reach 8log10 (99.9999%)
Efficient & Cost-saving
1, Pre-shredding permits effective sterilization; Up to 80% volume waste reduction
2, The autoclave chamber can be equipped with a paddle to assist in feeding(applicable to capacity≥300L )
3, The chamber and pipes has thermal insulation which can reduce the heat consumption
4, Simple installation, fully automatic operation, easy operation, saving labor and costs.
Structure of Autoclave
1, Upper chamber
The upper chamber includes an automatic loading door and chamber for loading the waste. The material is 316L stainless steel which guarantee the service life and anti-corrosion.
It has a hopper which can help the medical waste enter into the shredder easily.
2, Shredder
The shredder is built into the chamber and provided with double rotating shafts. With automatic reverse rotation to prevent jamming. It shreds the waste to small pieces following the needs of customer.
The blades are made of high-quality alloy steel (55SiCr) which is high toughness and impact resistance. The blade material can also be customized according to customer requirements.
3, Lower chamber
Lower chamber is comprise of side door or bottom door(depends on autoclave capacity) and waste cart or waste collection plate. The material is 316L stainless steel which guarantee the service life and anti-corrosion.
For MWT-100 and MWT-150, The sterilization chamber has drawer type unloading system. It can also help unload medical waste which can save labor.


4, Control cabinet
The control cabinet consists of necessary interface elements to control all the valves, motors and hydraulic station.
The Siemens 7'' touch screen can display sterilization time, temperature, pressure, time, alarm, working curve and all parameters.
Printer can print sterilization time, pressure, temperature and real-time data for traceability.
5, Sealing door
The sealing door adopts a silicone rubber gasket and pneumatic seal structure. The door open and close is driven by hydraulic pressure. It also has safety interlock device.
*If the doors are not closed, the program cannot start
*If the chamber has pressure, the doors cannot open
*It has a multiple alarm system for the sealing door to prevent misoperations, water cuts and power cuts from affecting the system.

6, Pipeline system
The piping system consists of control valves, safety valves and stainless steel pipes.
*The control valve adopts Germany GEMU pneumatic valves and solenoid valves.

(Germany GEMU pneumatic valve)
* It has safety valves to protect the products and operators. When it is overpressure, the safety valve will open to release the pressure. When the pressure is under the setting limit, it will close.
* Stainless steel pipes: The pipes adopts 304 stainless steel and covered with thermal insulation material whose temperature is above 45℃
Working Flow
Loading-Shredding-Pulse-Heating-Sterilization-Draining-Drying-Unloading

(Siemens Touch Screen)
Loading: Press "T-door O(open top door)" button, the door will be opened automatically. The operator will put the medical waste bag into the shredder chamber (if the product has dumper, the dumper will pour medical waste into shredder automatically.) When the shredder chamber is full, please close door.
Shredding: After the top door is closed, the shredding motor starts to shred medical waste. When it detects the electric current back to empty loads status, the shredding motor will stop.
Pulse: The vacuum pump will work to drain off the cold air inside of chamber, to make the steam penetrate the medical waste efficiently. It will evacuate chamber pressure to -70~ -80Kpa.
Heating: The steam inlet valve will be opened and steam enters into the chamber. When the temperature reaches to the setting value. It will turn into sterilization phase.
Sterilization: The steam valve will be controlled by chamber pressure and temperature. It will keep the chamber pressure between 138℃±2℃, 15min or 134℃±2℃,30 min. The parameters can be modified by customers.
Draining: After sterilization, discharging valve will open to exhaust air in the chamber.
Drying: When the chamber pressure reaches to setting value, vacuum pump will start to dry medical waste.
Unloading: Open the side door, unloading medical waste.
