Dental Clinical Waste Disposal Management Autoclave Shredder Description:
Dental clinical waste disposal shredding autoclave is primarily applicable to a wide range of applications in dental, veterinary and small clinics, hospitals and operating rooms (OR). WRMS series horizontal medical hazardous waste autoclave shredder is newly developed and produced by our company. Medical hazardous waste autoclave shredder 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》. Crushing, sterilization and drying can be done in only one autoclave, thus avoiding second pollution. Horizontal medical hazardous waste autoclave shredder saves space. And can greatly reduce the costs of packaging, transportation and burying.

Why do we need dental clinical waste disposal?
Biomedical waste (BMW) is an emerging occupational and environmental health hazard in the healthcare platform. Any form of BMW generated in hospitals during diagnostic, surgical, patient management, antibiotic, and radioisotope processes requires proper treatment and disposal. In the dental field, mercury wastes, dental amalgam wastes, lead and silver-containing wastes are often found, which pose serious health risks and are also environmental hazards. This can also have an impact and risk for airborne pathogens if not handled and disposed of properly. All these contaminated wastes, such as syringes, needles, sharps, blood-soaked gauze, etc., can lead to infections and therefore require shredding and sterilization of dental wastes as well as animal clinics to achieve non-hazardous disposal of dental wastes.

 

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

Dental Clinical Waste Disposal Management Autoclave Shredder Structure & Characteristics:
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 with no blind angle, can meet GMP standards.

2. Feeding port is on the top of the machine with an electric sliding door sealed with a gasket. The pneumatic lifting discharge door, which is safe and reliable, is on the bottom.

3. Lever-type promotion and demotion unloading gate which is painted with Teflon. Additional manual locking systems will make it much safer.

4. Chamber and jacket have ports for temperature and pressure sensors.

5. Pipe system contains a water pump, water level controller, vacuum pump, safety valve, angle valve, filter, non-return valve, steam trap and pressure controller.

 

Double-shaft dental clinical waste disposal shredder system
1. The dental waste disposal machine adopts a medium load shear type for crushing.

2. Horizontal medical hazardous waste shredder 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.

4. Autoclave with shredder equipped with heavy alloy blade, not only has strength and hardness but also has the function of automatic reversal protection when meeting unbreakable materials, which can efficiently complete the crushing work of complex medical waste at a low cost.

5. The shredding system can crush dental waste containing metal products, glass products, plastic products, rubber and textiles, showing users satisfactory adaptability and tolerance.

 

Water supply & vacuum system
1. Water supply system is composed of a pump, level controller, angle valve, non-return valve, etc. The user connects the 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.

Control System
1. The horizontal medical hazardous waste autoclave shredder 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.

2. The horizontal medical hazardous waste autoclave shredder has the control and protection functions of temperature, pressure, liquid level, time and other system operating parameters in the sterilization operation stage, which can ensure the best sterilization effect of medical waste after crushing.

Horizontal Medical Hazardous Waste Autoclave Shredder Procedure:
Medical waste is into the cavity from the top of the door seal after the full top seal the door is closed and locked, the operator has to run one machine preset sound processing program, the program is run as follows:

1. Loading: 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 shaft 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 Temperatureof134 ℃ ~ 138℃..

3. Vacuum: Vacuum the inner cavity of the sterilizer, enter steam operation, repeat several times (generally take three times), then vacuum again, after the pressure of the inner cavity reaches the lower limit of pulsation, the program turns into the heating stage. After this stage, the cold air exclusion rate of the inner cavity can reach more than 99% to ensure that there are no dead corners in the inner cavity and that sterilization is qualified. (The set parameters are: pulsation three times, pulsation upper and lower limits are. (The parameters can be adjusted).

4. Heating: Steam enters the inner chamber through the sterilizer sandwich and heats the waste, while the inner chamber trap opens intermittently to discharge the water produced by steam condensation. When the temperature of the inner chamber reaches the set value (generally taken as 134°C), the program moves to the sterilization phase.

5. Sterilization: When the pressure in the jacket reaches a set value, Open connecting valve. Steam enters the chamber from the jacket. When the temperature in the chamber REACHES 134℃ ~ 138℃, Keep for 4 ~ 10 minutes.

6. Exhaust: The bottom outlet valve opens to discharge the water and exhaust gas in the outlet chamber, and the pressure in the chamber drops to the set value and enters the program branch drying stage.

7. Dry: The vacuum pump opens to make the inner cavity evacuate, while the sandwich maintains a certain pressure and temperature to play the role of drying, the inner cavity drying time (generally needs 12-15min, in 0-99min can be set at will) to the exhaust valve and the vacuum pump close, the return valve opens to make the inner cavity back to zero pressure. When the pressure in the inner cavity rises to -10KPa, the program turns to the end stage.

8. Uninstall: Open the door at the bottom of the material and unload the material to the material transfer car.
