Large hospitals typically use larger medical laundry equipment due to the substantial amount 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 garments inside.
The laundry service used by the institution is a crucial step in preventing hospital-acquired infections. The textiles washed include staff uniforms, patient clothing, bedding, etc. Prior to washing in the laundry room, items must be identified and categorized, then placed into medical washing machines, hospital dryers, and other equipment for washing or drying. Clothing contaminated with bodily fluids or secretions, which pose a risk of hospital-acquired infections, must be isolated and sanitized. Meanwhile, the laundry room staff must take protective measures, and the washing process must be standardized to prevent cross-contamination. Ensure that the laundry is clean, free of watermarks, stains, and odors, and hygienic.

All clothes must be washed within the specified time frame, followed by a drying and dehumidification process. The purpose of the large-scale industrial drying equipment is to quickly remove moisture from the clothes. A must-have feature in the hospital's large medical washing equipment is the sterilization function, which is typically achieved through infrared sterilization or high-temperature sterilization.

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 and also includes manual operation. It ensures continuous and long-duration operation with a large capacity, with all connections between the main shaft and flange disk undergoing heat treatment to prevent deformation at high speeds, thereby extending its service life. The body and frame are joined using CO2 protected welding technology, ensuring tight and durable connections; heating methods include steam heating and electric heating options. The development of a new gas-powered hospital dryer model is also underway. Under the suction force of the fan, fresh air enters through the intake, exchanges heat with the radiator, becoming dry hot air, which then exchanges heat with the tumbling textiles in the drum. Afterward, the air is exhausted from the unit, and the textiles in the drum gradually evaporate moisture under the dry hot air to achieve drying. Compared to steam dryers, the direct combustion hospital dryer does not require secondary conversion of thermal energy, resulting in more efficient energy utilization, lower losses, and higher drying efficiency.

Medical washing machines are mainly divided into types and capacities. By type, they include semi-automatic horizontal washing machines, fully automatic washing machines, and sterilization isolation washing and drying machines. By capacity, they come in various sizes such as 20 kg, 30 kg, 50 kg, 70 kg, and 100 kg.
Medical-grade washing machines are an innovative variation of standard washing machines, specifically designed laundry equipment for hospital laundries, which are washing machine products with a capacity exceeding 20 kilograms, used in various hospitals, health centers, and other sanitation institutions.
