Hospital laundry room construction should initially plan the functions of each part. The contaminated area is for linen collection, sorting, and washing, while the clean area is for drying, disinfecting, and post-processing of washed linens. A well-defined separation system ensures safer and cleaner linen washing. The laundry room needs good ventilation, which is also beneficial for the laundry equipment. Ensure no backflow from soiled to clean linens; all signs should be properly posted, and linens should be arranged in designated areas. Hospital laundry equipment factory process: The process for collecting linens includes collection, transportation, sorting, washing, drying, folding, storage, and use. Any issue in these steps can affect the final result. Conduct microbiological contamination risk analysis for each step, identify critical control points, and eliminate or reduce risks. After transporting to the laundry room, disinfection must be done before washing. Disinfection uses chlorine-containing disinfectants, with immersion time exceeding 30 minutes. The effective chlorine content for general items is ≥500mg/L, and for contaminated items, ≥2000mg/L. Boil for 20-30 minutes, and use detergents for 1 hour in washing. Post-washing clothes should be dried and folded using specialized equipment, stored in clean and dry areas, and transported in closed containers to avoid contamination. If washed clothes are suspected of being contaminated, they should be washed again.
Laundry room equipment handles a variety of linens frequently, including patient garments, ward sheets and pillowcases, operating room gowns, and medical staff uniforms, all requiring daily water washing for cleanliness. The operation of laundry equipment is strictly regulated to minimize contamination. A few days ago, my colleague inspected a series of intelligent medical linen washing, ironing, and drying equipment, which was successfully installed and adjusted, and has now begun trial operation. The dryer's (Dragon) intelligent control, high efficiency in removing wrinkles, and energy-saving features will enhance the laundry room's drying and sterilization capabilities once production begins.
Why does this new drying machine system become a key sterilization factor in medical laundry? We will provide a detailed explanation. Laundry staff need to ensure strict sealed transportation from the collection of linens to the journey, and classify and treat the collected linens before cleaning. Heavily soiled linens (with body fluids and excrement stains) require separate soaking, followed by pre-washing. A special reminder is needed here, for example, body fluids cannot be directly placed in the washing machine. They should be soaked in warm water around 30℃ with an appropriate amount of stain remover for ten minutes before being washed. Only then can blood stains be removed; for human excrement, general water rinsing is sufficient, and stubborn stains can be removed by soaking with the right amount of laundry detergent. Linen washing must be carried out according to the standard procedure, which includes: a 5-minute water rinse, a 20-minute main wash (with cleaning detergent and water temperature at 50℃), draining, a 5-minute rinse with neutralizing agent, a 5-minute medium spin, a 5-minute high spin, and a 5-minute sealed sterilization to complete the entire washing process. After washing, all linens must be loaded into sealed delivery vehicles before being sent to various departments for use. Linens that cannot be delivered promptly should be placed in an ultraviolet storage cabinet until they are ready for delivery, ensuring the cleanliness of the linens and preventing any contamination by pathogens.
Isolation washing extractors are primarily used to process linens sorted with body fluids or requiring special treatment, as well as returned linens. After washing and extracting, they are sent to a steam dryer for drying. They achieve separate filling and removal through an isolation wall, separating clean and soiled areas to prevent cross-contamination, offering advantages in handling highly soiled, high-bacteria items like hospital bedding, surgical gowns, and lab linens. Such production tools often mean higher production efficiency, high cleanliness, and stringent hygiene standards. Special components are chosen to meet the requirements of a 100,000-class clean room. The design of the isolation washing machine meets truly high medical washing standards. Custom washing and extracting processes: after the main wash, the linens are first spun at high speed, then fresh water is added for rinsing based on the weight of the linens. Through multiple cycles of extracting and adding fresh water, this process ensures good rinsing while saving water consumption and labor time. The fresh water consumption per kilogram of dry linen can be reduced from the traditional 18L to less than 12L; total washing time can be saved by about 15%, approximately 10 minutes. An internal weighing unit is used for precise measurement, replacing traditional level control technology. The automatic weighing system feeds the dry linens, and water, chemicals, and steam are added proportionally based on weight. The computer continuously monitors the extraction process. The fully automatic washing machine can pre-set moisture content for different fabric types, with the machine determining the drying time. It can maintain a consistent moisture content for the same type of linen, ensuring consistent finishing and drying results. It achieves up to 350G of centrifugal force, resulting in ultra-low moisture content and reducing energy consumption.
Again, let's discuss the current status of clothing washing and drying: In the laundry industry in our country, most types of clothing (operating room attire, towels, patient gowns, nurse uniforms, white coats) are dried using drum-type single machines. A small number of nurse uniforms and white coats are hung to dry in tunnel dryers, and a considerable portion is air-dried. Although the drying machine indicates temperatures exceeding 60°C, due to the intertwined fabrics, they pull on each other, resulting in clothes near the drum wall being over-dried while those in the center remain damp, especially when the laundry equipment is over-packed. This leads to unguaranteed sterilization temperatures, poor effectiveness, and a higher risk of cross-contamination. Therefore, it is recommended to choose laundry and drying equipment with a sanitation isolation system. Older models use dryers with large-scale heaters, which have quick heat exchange and high energy utilization; they heat up fast and reduce drying time. With a load of 80% and moisture content of 50%, the drying time is only 30 minutes. The inner drum features high-density ventilation holes for sufficient heat to pass through the fabrics, ensuring they are thoroughly dried in a short time. It is equipped with a large-diameter loading door for easy handling of fabrics, and the door design includes an anti-overlap feature to prevent fabric tugging. A safety interlock device ensures that the machine does not start when the loading door is open. The full computer control allows for precise setting of drying time and temperature. The computer controller features a touch-sensitive button design for flexible and reliable operation. The computer control is installed in a recessed design, enhancing the overall aesthetics of the machine.
The latest models of dryers utilize isolated hanging drying technology, effectively cutting off the pathways of bacteria. A detailed analysis reveals the following main reasons: Firstly, using the older model dryers (single-machine operation) reduces the load of clothes, increases the gaps between garments, ensuring even heating and reaching the required clean temperature. However, this method leads to high costs in the drying process. But with the isolated hanging method, drying at 80℃-110℃ for 8-10 minutes guarantees cleanliness under high temperatures. Especially for surgical garments and linens, patient uniforms, isolated hanging drying is essential. Secondly, the dryer's hanging system allows for vertical drying, preventing wear and tear from rolling friction, and achieving a degree of flattening after drying. There is no post-drying creasing or wrinkling, significantly improving the quality of drying. This introduction to using dryers and other laundry equipment can be referenced; do not copy from small workshops like Shi Meiquan, Xia Mou, etc. Once again, I send my regards to their families, wishing them peace and health. Additionally, the high-efficiency working method of the new dryer can reduce labor intensity and does not require technical skills from the operators, truly achieving energy saving and emission reduction, and lowering overall operational costs. The quality of laundry and drying is a major public welfare project concerning the health of hundreds of millions of people. Achieving sterilized drying and updating equipment is crucial, and it has become an indispensable important part of medical logistics support. This equipment can be integrated into the intelligent washing configuration process according to actual needs.

Currently, only a very small number of domestic hospitals use forward-to-back medical washing machines for laundry equipment, while most laundry rooms still rely on the traditional forward-to-forward washing equipment. This type of equipment requires loading and unloading linens on the same side during operation, with clean linens entering the dirty area directly upon exiting the machine, making them highly susceptible to contamination. Generally, the same employee is responsible for loading and unloading the same washing machine, often leading to cross-contamination. Additionally, the movement of employees and vehicles can frequently result in cross-contamination between clean and dirty linens. To standardize the laundry process, the following requirements should be met: (1) Unloaded dirty linens should be stored in an appropriately isolated space or a physical separation line (such as a wall), away from the storage and dispatch areas for clean linens. (2) Dirty linens should be washed as quickly as possible. Ideally, linens should be processed immediately upon arrival at the laundry room; continuous washing should be maintained to minimize the time between delivery and washing, avoiding extended storage of dirty linens, not due to disease transmission risks, but to prevent stain removal difficulties and potential mold growth, which can also affect washing quality. For heavily contaminated body fluids or liquids that may leak and contaminate other linens, these linens should be stored in airtight, non-penetrable bags in addition to suitable laundry bags.
In recent years, medical institutions have increasingly taken notice, and the procurement of hospital laundry equipment has been brought to the agenda. For hospitals, bedding, patients' clothes, and operating room linens all require daily washing to ensure patient safety and meet certain hygiene standards before reuse. So, how do we choose the right medical washing machine model? Let's break it down in detail. Currently, there are mainly three types of medical washing machines on the market: standard medical washing machines, fully automatic disinfection medical washing machines, and hygiene isolation washing machines. Each type serves different purposes, so hospitals need to clearly define the use of the medical washing machine before purchasing to select the most suitable model for their needs. If the hospital only needs to clean simple linens, a standard medical washing machine would suffice; these machines are more affordable and have a simple structure, making maintenance and repair convenient in the future. If higher requirements are needed, we recommend using a fully automatic medical disinfection washing machine, a multi-functional unit that can complete the entire washing, drying, and disinfection process with just a pre-programmed and one-button start. As for pricing, the fully automatic models, due to their complex manufacturing process, are naturally slightly more expensive than standard medical washing machines, and each hospital should decide based on its own situation.
The fully automatic hospital laundry equipment features a large LCD screen for Chinese display, offering 30 programmable options. With a simple structure, the basic frame is equipped with four shock-absorbing springs and eight damping buffers, ensuring minimal vibration during the high-speed spin cycle of medical washers. This allows for installation on any floor without issues. Both the inner and outer drums of the hospital washing machine are made of high-quality 304-grade stainless steel, highly resistant to corrosion, and can be used for an extended period without rusting. The transmission section utilizes an imported variable frequency control system, characterized by its low starting current, effectively reducing the occurrence of excessive current issues during operation, enabling smooth operation with just a single transmission. The new hospital washing machine is equipped with multiple early warning devices, simultaneously displaying water level, water temperature, speed, and current, facilitating timely detection of problems. From the design stage, we considered heating methods and can customize steam and electric heating water temperature options to meet the needs of various industries for laundry.
Medical laundry machines are equipment with automatic disinfection and sterilization functions, custom-made to meet the hospital's requirements for linen cleanliness and sterilization. The new medical laundry machines can fully sterilize bed linens, pillowcases, and clothing, ensuring safe use. The collected linens first require pretreatment, separating bloodstained items, treating them separately with cold water and bloodstain removers, while the rest are soaked in a medical laundry machine with sterilizing agents. After that, start the medical laundry machine, and it will automatically run for 30 minutes. The medical laundry machine features one-touch start and stop functions. After washing and sterilization, only the clothes are placed in the dryer, while the bed linens and pillowcases are simply ironed. Some advantages during use include: first, high-temperature sterilization, where steam or electric heating during the washing process achieves high-temperature sterilization, thoroughly cleaning the linens to meet health washing standards. With the addition of washing materials and high-temperature washing, the sterilization effect is very pronounced. Due to the improved washing performance, the linen washing time is effectively reduced, thereby decreasing wear. The fully automatic hospital washing equipment uses high water temperatures to wash, which can also effectively prevent the deformation or creasing of staff uniforms. High water temperatures activate the washing agents, penetrating deep into the fiber tissues to strip away stains from the linens, achieving a deep cleaning effect. Compared to ordinary washing equipment, the washing time is significantly shortened, effectively saving water and electricity. To reduce and prevent cross-infection with viruses and diseases caused by human factors or management, the following precautions should be taken during the operation of medical laundry machines: 1. Strictly control the cleaning and disinfection areas, implement standardized zoning and sorting management, separate the sending and receiving areas, and differentiate based on the cleanliness of the items, the type and nature of the stains, to avoid cross-contamination of linens. 2. The washing process of hospital washing equipment should flow from soiled linens to clean linens in the forward direction, prohibiting reverse flow to reduce the chance of secondary contamination and virus transmission; use detergents and disinfectants during the washing process, in conjunction with high-pressure and high-temperature disinfection and ultraviolet radiation. 3. If conditions permit, use an isolated fully automatic hospital washing machine and implement an isolated health washing method to prevent cross-infection of fabrics and clothing. 4. Staff should wear disinfected and washed clean uniforms during work and wear disinfection gloves when necessary.
Hospital laundry equipment primarily provides daily washing and disinfection of hospital linens, eliminating the need for external laundry services. It allows for direct washing within the hospital and subsequent use in patient rooms, ensuring both speed and hygiene are monitored, offering peace of mind to users. Most current hospital laundries still operate on a single-machine washing model, lacking modern operational methods and increasing the workload for laundry staff. To address this, most hospitals now opt to purchase fully automatic medical laundry equipment to enhance overall linen washing efficiency and alleviate the heavy workload. Traditional laundry machines could only wash, without the automatic drying function, requiring staff to manually remove linens and then dry them in a脱水 machine after each wash, which is not only labor-intensive but also cumbersome. The use of medical washing machines can completely resolve this issue, making the hospital laundry more user-friendly. When purchasing medical washing machines, please prioritize quality over price; reasonable pricing is sufficient.
