Large hospitals typically use larger medical laundry equipment due to the high volume of bedding and clothing that need to be cleaned daily. This allows for a single wash cycle for items like clothes and bedding, while also providing high-temperature disinfection. The large washing machines are equipped with an automatic water filling system, which adds the appropriate disinfectant based on the type of clothing being washed, ensuring even disinfection for the items inside.
Medical washing machines are primarily categorized by type and capacity. By type, they include semi-automatic horizontal washing machines, fully automatic washing machines, and sterilization isolation washing and drying machines. By capacity, they range from 20 kg, 30 kg, 50 kg, 70 kg, to 100 kg types.

The inner drum and outer shell of the hospital dryer are meticulously crafted from high-corrosion-resistant 304 stainless steel. It features an automatic control system for varying temperatures, with the entire process controlled by a computer, complemented by manual operation. It ensures continuous, long-duration operation with a large capacity, with all connections between the main shaft and flange disk heat-treated to prevent deformation at high speeds, thereby extending its service life. The body and frame are linked using CO2 shielded welding technology, ensuring tight and durable connections; heating methods include steam heating and electric heating options. The development of a new generation of gas-powered hospital dryers has also commenced. Under the suction force of the fan, fresh air enters through the inlet, exchanges heat with the radiator, becomes dry hot air, and then exchanges heat with the tumbling textiles in the drum. Afterward, it is exhausted from the machine, and the textiles in the drum gradually evaporate moisture under the dry hot air to achieve drying. Compared to steam dryers, direct combustion hospital dryers do not require secondary conversion of heat energy, resulting in more efficient energy utilization, lower losses, and higher drying efficiency.

Isolation medical washing machines feature a microcomputer control system, offering both automatic and manual options. They are capable of large-capacity water washing with high cleaning efficiency. Various automatic washing programs can be edited, allowing the laundry staff to simply select the appropriate program based on the linen's specific condition. The machine's control panel can independently control the operation of the medical washing machine, with an LCD display indicating the washing progress. The purpose of linen processing in hospitals is to remove or kill microbial contamination, which involves three stages: water washing, sanitization, and dilution. The washing stage should ensure all fabrics are clean and hygienic by removing pollutants from the fabrics. Simultaneously, all fabrics should be chemically or thermally sanitized to kill or reduce the number of viable microorganisms. To dilute and reduce the number of viable microorganisms on the fabrics, hospital washing machines should at least perform two rinsing cycles to minimize microbial levels and remove detergents and disinfectants from the washing wastewater.

The laundry cleaning work used by institutions is a crucial step in preventing hospital-acquired infections. The textiles washed include staff uniforms, patient clothing, bedding, and more. Before entering the laundry room and undergoing water washing, identification and classification are required. Then, they are placed into medical washing machines, hospital dryers, and other equipment for washing or drying. Items with hospital-acquired infection risks, such as those contaminated with bodily fluids or secretions, must undergo isolated and hygienic washing. Meanwhile, laundry room equipment operators in the hospital must also take protective measures, and the washing process must be standardized to avoid cross-contamination. Ensure that the laundry is presented clean and free of water stains, dirt, and odors, maintaining a hygienic appearance.
Medical washing machines are an innovative variation of standard washing machines, designed as laundry equipment for hospital laundries, which are laundry products with a washing capacity of over 20 kilograms, specifically applied in various hospitals, health centers, and other healthcare institutions.
