| dc.description.abstract | Due to the impact of the Covid 19 epidemic, people's awareness of disease
prevention has increased, so antibacterial products were born. In particular, current
products tend to use ultraviolet rays to disinfect and kill bacteria, specifically UV rays. Farultraviolet C (UVC) light has shown its capability to deactivate microorganisms on
surfaces. However, several factors influencing the effectiveness of far-UVC surface
disinfection, such as surface roughness, pores, electrostatic charge, wetness, and
temperature, remain to be fully understood. In addressing the persistence of bacteria and
viruses on product surfaces, a synergistic approach combining temperature and UVC rays
has been introduced. Warm air circulation convection drying technology, which utilizes
circulating warm air within a drying chamber to meet the object's surface, induces the
evaporation of moisture within the object. This moisture is then carried away by the
airflow. Integration of warm air circulation convection drying technology with ultraviolet
sterilization resolves a significant limitation of traditional sterilization methods. The
continuous airflow, facilitated by a fan based on drying technology principles, prevents
bacteria from concealing themselves in the sterilization chamber. Through the combined
action of warm air temperature and UV rays, this approach achieves comprehensive
sterilization, eliminating up to 99.99% of microorganisms, including bacteria, viruses,
molds, and more. This significantly reduces the risk of transmission, infection, and crosscontamination. The effectiveness of this combined heating and UVC method has been
validated through the development of a machine designed to verify its performance. This
machine achieves optimal disinfection efficiency by testing on many types of bacteria and
creating a comparison table to compare with products on the market. Not only that, but the
machine also has a mist spray mode, helping users to ferment foods that need to be
fermented. | en_US |
