Centralized Biohazard Waste Processing Plant MDU-10 170KW Steam Generator

The MDU-10 is a heavy duty treatment plant for institutions that generate medical waste every day of the year. Its frame carries the shredder, microwave cavity, holding section and discharge conveyor as a single tested assembly, which keeps alignment stable after transport and shortens on-site installation. Maintenance points are grouped on one side of the machine, and wear parts such as shredder blades and door seals can be replaced without dismantling the line.

• Verified sterilization performance: Microwave treatment at 2450 MHz and a holding temperature of at least 95 degrees Celsius for more than 45 minutes delivers a microbial inactivation of no less than 6 log10, tested with Bacillus subtilis var. niger spore ATCC 9372 as the biological indicator.
• Integral shredding before sterilization: A double-shaft shredder reduces bags, sharps containers and wrapped waste before the microwave stage, and an automatic reverse function clears blockages without opening the chamber.
• Integrated steam generator: The steam generator needed for the holding section is supplied as part of the unit, which means no separate boiler room, no fuel storage and no pressure vessel inspection regime.
• Single-operator PLC control: The process sequence, door interlocks and alarm handling are managed by a PLC, so one trained operator can run the line from the HMI panel with batch parameters recorded.
• Low environmental impact: Treatment is electric and closed; no acid gas, dioxins or contaminated steam are released, and the residue is sterile and suitable for municipal landfill or recycling routes.
• Small utility footprint: Installation needs a level floor, three-phase power and a ventilation connection; the compact arrangement suits existing waste rooms rather than requiring a new building.

In practice the machine is started in the morning, brought to operating temperature, and then fed container by container. Each container is lifted, emptied and returned; the shredder reduces the waste; the microwave section and holding section sterilise it; and the discharge conveyor fills the receiving container. When the receiving container is full it is sealed and replaced. The operator's role is limited to loading, container exchange and reading the panel, which is why the unit is specified for one person per shift.

Applications range from single hospitals treating their own waste to regional plants that serve a district of clinics and laboratories. The machine accepts blood and blood products, dialysis waste, sharps, human tissue and body parts, animal tissue and carcasses, laboratory specimens, cultures, isolation waste, surgery and pathology samples, intravenous bags and associated tubing, and contaminated gloves and gowns. Pathological and anatomical waste can be treated, which is a common limitation of conventional autoclaves. The treated residue can be landfilled or routed to a recycling plant.

Packaging follows the requirements of long sea freight. External surfaces receive anti-corrosion treatment, small parts are boxed and listed by position, and fragile items such as sensors and the HMI panel are packed in foam-lined cases. The shipment includes a full documentation set: general arrangement drawing, utility connection schedule, maintenance manual and spare parts list. Installation usually takes a few days including leveling, connection of power and ventilation, and a trial run with the customer's own waste.
