Sterilization function of dryer

Creating a cozy summer home that serves as a peaceful retreat requires careful selection of appliances that enhance comfort without compromising on style or efficiency. At Appliances 4 Less Little Rock, we cater to residents in Little Rock, Benton, Conway, and Pine Bluff with an array of open box, scratch, and dented appliances that are perfect for elevating your summer living. Here’s our guide to the essential appliances for a cozy summer home.

Once seen as a tool for drying clothes, the dryer has quietly evolved into the invisible guardian of family health. No longer content with simple dehumidifying functions, it is using technology as a blade to wage a silent battle in the microscopic world-against invisible bacteria, viruses and odors. This is not only the evolution of home appliances, but also the eternal pursuit of human healthy life: in the fast pace, you can still feel the peace of mind gently wrapped by technology.

(1)、UV sterilization

UV sterilization technology, like an invisible blade, in the micro-level precise fight against bacteria and viruses.

1. principle

UV sterilization technology with a wavelength of 253.7 nm UVC short-wave ultraviolet as the key. Photon energy can penetrate the cell wall of bacteria and viruses directly. When irradiated, the pyrimidine bases in microbial DNA or RNA molecules absorb light energy to form Pyrimidine dimers, which blocks DNA replication and transcription, and makes microorganisms sterile, final death.

2. characteristics

Compared with the traditional chemical bactericides, ultraviolet bactericides have obvious advantages. It does not need chemicals, will not remain harmful ingredients in clothing, infant clothing, sensitive skin is very friendly to people. And sterilization without high temperature, can cooperate with low temperature drying process, effectively protect the heat-resistant fabric.

(2)、Silver ion sterilization

Silver ion sterilization technology brings long-term sterilization protection for clothing with unique mechanism.

1. principle

Silver ion sterilization technology through the built-in silver ion generator or nano-silver coating, continuous release of positively charged silver ions (Ag +) . These tiny particles can actively adsorb on the surface of the negatively charged bacterial cell membrane, destroy its electrolyte balance, and lead to leakage of cellular contents. At the same time, silver ions enter the bacteria and bind to thiolase (- SH) , inactivating the enzyme protein and blocking metabolism and energy supply.

2. characteristics

The biggest advantage of silver ion sterilization is its long-term effect. Even after the drying process, the nano-silver coating can release trace silver ions and inhibit the growth of mold during the storage of clothes. Silver ion sterilization at room temperature can be effective, without high temperature auxiliary, so on wool, silk and other delicate fabrics very friendly, really gentle sterilization.

(3)、Plasma sterilization

Plasma sterilization technology, like an ion storm, can deal with a variety of complex environment while sterilization.

1. principle

Plasma sterilization technology produces a large number of positive and negative ions (o 2-, H + , etc.) by high-pressure ionization of air. These ions will actively attach to the surface of bacterial cells, forming an electric field that perforates the cell membrane and causes bacterial death. At the same time, the reactive oxygen species (such as ozone, hydroxyl radicals) in the plasma can react with organic pollutants in the air (such as odor molecules) to oxidize and decompose them into carbon dioxide and water.

2. characteristics

The core advantage of plasma sterilization technology is its versatility. For Pet family, it can quickly decompose pet dander and odor on clothing; for smoking environment, it can effectively remove smoke residue. In addition, the negative ions produced by the plasma generator can also improve the air quality in the drum and reduce electrostatic generation. Compared with ultraviolet sterilization, plasma technology is not limited by light conditions, can be started at any time, especially suitable for night or no natural light environment.

(4)、Pasteurization

Pasteurization technology, with its unique low-temperature heat, in the sterilization and clothing to find the perfect balance between.

1. principle

Pasteurization technology takes the low temperature heat of about 60 °C as the core, and makes the protein in the bacteria undergo irreversible denaturation by continuous heating. When the temperature rises to 55-60 °C, the lipid bilayer structure of the bacterial cell membrane softens, resulting in the leakage of cellular contents. At the same time, the three-dimensional structure of the enzyme protein is destroyed, and the catalytic activity is lost. Compared with the traditional high temperature sterilization (above 70 °C) , the pasteurization technology can kill more than 99% of bacteria and minimize the damage to clothing fibers.

2. characteristics

The greatest value of pasteurization is its balance. For blended fabrics or with printing, embroidery clothing, low temperature environment can avoid shrinkage, deformation or color fading. In addition, the energy consumption of pasteurization technology is only 60-70% of high temperature sterilization, which meets the needs of modern families for energy conservation and environmental protection.

Conclusion

The evolution of dryer sterilization technology is a vivid epitome of the interweaving of science and Technology and humanity. It not only redefines the standard of clothing care, but also reflects the eternal yearning for a healthy life. In the future, with the further integration of materials science and intelligent control, sterilization technology will be more efficient and environmentally friendly, bringing more comfortable life experience to families around the world.
