Hospitals are essential institutions for protecting public health and saving lives. While people often focus on consultation rooms, operating rooms, and sterilization departments, the hospital laundry room is easily overlooked despite its critical role. Medical textiles such as bed sheets, patient gowns, surgical drapes, and healthcare uniforms are frequently exposed to blood, bodily fluids, and various pathogens. Any weakness in the laundering process can easily cause cross-contamination and threaten the safety of both patients and medical staff. A well-designed laundry equipment system tailored to hospital requirements is not only a tool for improving linen-processing efficiency, but also an indispensable physical barrier within the hospital infection-control system.
The main washing equipment is the core of the entire laundry room and the first line of defense against the spread of pathogens. It is generally divided into two categories: conventional fully automatic washer-extractors and medical barrier washer-extractors, which are intended for distinctly different applications. Conventional fully automatic washer-extractors usually feature a single-door design and are suitable for low-contamination environments such as community clinics and small outpatient facilities. They integrate washing and extraction for routine ward linens and include multiple preset programs for intensified removal of bloodstains and pharmaceutical stains. They also support high-temperature disinfection above 70°C to meet basic hygiene requirements. Barrier washer-extractors, by contrast, are standard equipment in medium-sized and large hospitals and infectious disease departments, and are the key feature that distinguishes medical laundry processing from ordinary commercial laundry operations. They use a double-door, pass-through design and are installed within a partition wall of the laundry room. Soiled linens are loaded from the contaminated sorting area on one side, and after washing and high-temperature disinfection, they can only be unloaded through the door on the clean side. This physically separates the contaminated and clean areas, preventing polluted air and residual pathogens from recontaminating clean textiles. These machines are specifically designed for high-risk linens such as infectious textiles and surgical gowns and fully comply with medical textile washing and disinfection requirements. Both types of equipment use corrosion-resistant stainless steel inner drums that can withstand prolonged exposure to disinfectants and prevent rust from becoming a source of secondary contamination.
After washing, drying equipment completes the final stage of the disinfection process. Small medical institutions can use basic tumble dryers with capacities of 30–50 kg, relying on high-temperature hot air to dry textiles thoroughly and prevent bacterial growth in damp conditions; Grade III Class A hospitals and comprehensive medical centers are advised to use energy-efficient tumble dryers with capacities of 80–120 kg. Some models support high-temperature steam drying, allowing secondary sterilization to be completed during the drying process. For surgical drapes and other operating-room textiles, an independent high-temperature dryer can also be installed. Its fully enclosed, temperature-controlled process prevents surgical textiles from being contaminated by dust during drying.
After drying, the linens must be shaped and finished. Ironing and folding equipment directly affects the quality of the finished linens and the required labor cost. Flat linens such as bed sheets, duvet covers, and pillowcases can be rapidly finished with a roller flatwork ironer. Multi-roll models can perform ironing and moisture removal simultaneously, substantially increasing the processing speed for large quantities of linen; irregularly shaped textiles such as healthcare uniforms, surgical gowns, and isolation gowns can be processed with specialized ironing presses that shape collars, cuffs, waist sections, and other details, ensuring a neat and professional appearance. An automatic folding machine can be seamlessly connected to the flatwork ironer to complete linen separation, folding, and stacking automatically. This eliminates repeated manual handling, reduces the risk of clean linen contamination caused by personnel contact, and lowers laundry-room labor costs.
In addition, the laundry room must be equipped with supporting equipment to create a complete closed-loop process. Sorting tables are used for the initial classification of soiled linens upon receipt, separating ordinary textiles, infectious textiles, and surgical textiles to prevent mixed washing; separate transport carts for soiled and clean linen use sealed, color-coded designs and follow a one-way workflow without cross-use; an automatic chemical dosing system precisely controls the proportions of disinfectants and detergents, ensuring consistent disinfection performance while reducing errors caused by manual dosing; wastewater treatment equipment must also be installed to process effluent containing disinfectants and residual bodily fluids so that it meets medical environmental discharge standards. Small outpatient facilities may simplify the supporting equipment and retain only basic sorting tables and transport carts; comprehensive hospitals should install a complete range of auxiliary equipment to establish a one-way closed-loop process covering soiled-linen collection, washing, finishing, and clean storage.
Equipment configurations should be adjusted flexibly according to the size of the hospital. Community clinics and small private hospitals processing less than 300 kg of linen per day can use one 30 kg fully automatic washer-extractor, one small tumble dryer, and a basic ironing table to meet routine washing requirements; secondary hospitals processing 500–1,000 kg of linen per day should add a barrier washer-extractor, a 50 kg tumble dryer, and a single-roll flatwork ironer, while establishing separate contaminated and clean operating areas; Grade III Class A general hospitals, infectious disease hospitals, and rehabilitation centers processing more than 1,500 kg of linen per day must use multiple barrier washer-extractors, large-capacity tumble dryers, and a complete production line consisting of multi-roll flatwork ironers + automatic folding machines, together with a full range of supporting equipment, while strictly implementing a laundry workflow based on two zones and three separate passages.
The configuration logic of hospital laundry-room equipment must always center on “infection prevention and control.” The ultimate purpose of equipment selection, machine quantity, and spatial layout is to interrupt the chain of pathogen transmission while balancing processing efficiency with medical hygiene standards. Only by selecting barrier washing equipment, drying and finishing machinery, and supporting facilities according to the institution’s patient volume and the contamination level of its linens, and by establishing a one-way clean laundry process, can the laundry room perform its protective function effectively and provide an essential but often invisible line of hygiene and safety for patients and healthcare personnel.
