Medical Waste Autoclave With Shredder Disposal Equipment Application Areas：
With the outbreak of the new crown virus, a large number of medical resources are consumed every day. Among them, medical protective clothing is an indispensable anti-epidemic material that a doctor uses three sets a day. When the epidemic is severe, Wuhan will consume 100,000 sets a day. Protective clothing, as an item that comes into direct contact with patients, carries a large number of germs. If the waste protective clothing is not handled properly, it is easy to cause secondary pollution and become another serious source of infection. This protective clothing sterilization recycling machine can dispose of waste protective clothing for the first time. When the doctor leaves the isolation ward, takes off the protective clothing and places it on the machine, the equipment will first tear the protective clothing to pieces, and perform all-around sterilization without dead ends through the high-temperature sterilization method. It saves space and avoids the second spread of the virus.

Medical Waste Autoclave With Shredder Disposal Equipment  Description:
WRMS series medical waste autoclave with shredder is newly developed and produced by our company. It is widely used in hospitals, clinics, health centers and dentists, etc. It meets the standard of GB150-2011«Pressure Vessel» and TSG R0004-2009«Pressure Vessel Safety Rules». Shredding, sterilization and drying can be done in one autoclave, thus avoiding the second pollution. It saves space. And can greatly reduce the costs of packaging, transportation and burying.

Medical Waste Autoclave With Shredder Disposal Equipment  Technical Advantages :
For the convenience of the user, this medical waste autoclave with shredder adopts a built-in electric steam generator to produce steam as a sterilization medium, automatic water supply and water level protecting system.
The feeding port is on the top of the medical waste autoclave with shredder machine with an electric sliding door which is easy for loading medical waste.
Medical waste autoclave with shredder can ensure a thorough crushing, sterilization and drying within 90 minutes.

Medical Waste Autoclave With Shredder Disposal Equipment Structure & characteristics
1. Pressure chamber
(1) The chamber is a vertical pressure vessel with a jacket, good for pre-heating, drying and continuous operation. It is made of stainless steel SUS304. The inside surface is mechanically polished. smooth and no blind angle, can meet GMP standard.
(2) Feeding port is on the top of the machine with an electric sliding door sealed with a gasket. The discharging port is on the bottom with motor driving, lever-type promotion and demotion unloading gate which is Teflon painted. The additional manual locking system will make it much safer. Chamber and jacket have ports for temperature and pressure censers. The pipe system contains a water pump, water level controller, vacuum pump, safety valve, angle valve, filter, non-return valve, steam trap and pressure controller.
(3) Unloading gate is equipped with a PTC heater to ensure sterilized waste is dry and germ-free. A wheeled cart is for transferring finished waste.

2. Double shaft shredding system
The double shaft shredder machine adopts a medium load shear-type for shredding.
It is equipped with a single motor reducer, by a pair of gear wheels to drive a pair of knife axles to run simultaneously to shred. This low-speed, large torque system is strong and stable to shred all medical waste including, fabric, rubber, plastic, paper, glass, and a small piece of metal.
The system has an automatic back-running function. When something can’t be shredded, the system will back run automatically to self-protect.

3. Water supply &vacuum system
(1) Water supply system is composed of a pump, level controller, angle valve, non-return valve, etc. The user connects water to the pump, the system starts working automatically. When the water reaches the set level, the electric heater starts working to produce steam. When the steam temperature reaches a set degree, the autoclave starts sterilization for shredded waste.
(2) Vacuum system is composed of a vacuum pump, water separator, non-return valve, vacuum valve and water pipe. This is for removing wet and hot steam from the chamber after sterilization for cooling and drying.

4. Controlling system
The complete machine adopts PLC (Siemens)+HMI( touch scream ) for controlling and operating with three degrees of password for protection. All data can be saved or to be real-time printed.

Procedure
1. Feeding
Start the machine, open the feeding port at the top, and feed medical waste of about 80 liters. Close the door and confirm. And manually close the lock of the unloading port at the bottom.

2. Shredding
Start double axle shredding system to shred medical waste. At the same time, supply pure water into the jacket to set the level. Start the electric heater. PTC heating system of discharging port at the bottom also started to a temperature of 134℃~138℃.

3. Sterilization
When the pressure in jacket reaches set value, open the connecting valve. Steam enters the chamber from the jacket. When the temperature in the chamber reaches 134℃~138℃, keep 4~10 minutes for sterilization.

4. Cooling and drying
When set sterilization time finishes, the chamber exhausts steam and pressure relies on it. But the jacket and unloading port will keep on heating. When chamber pressure is the same level as outside, the vacuum system starts working for 15-20 minutes for cooling and drying. When timing finishes, stop heating in jacket and PTC. Germ-free valve open, and pour in germ-free air to the chamber to normal pressure.

5. Discharge
A wheeled cart is positioned under the machine. Manually open assistant locking system and motor open discharging port door. Sterilized medical waste is unloaded.
