Weakly acidic hypochlorous acid soft water (HClO) is a substance synthesized within the human body. It uses its powerful oxidizing power to kill viruses and bacteria that enter the body through mucous membranes, protecting the body from pathogens. Because hypochlorous acid water is synthesized within the body, it is harmless to humans and animals.
While alcohol, which has been widely used during the COVID-19 pandemic, poses fire safety concerns and can be irritating to the skin, hypochlorous acid water, which has been adjusted to a pH of 6.5 and a residual chlorine concentration of 50 ppm, can be used for a wide range of purposes, including hand disinfection and air sterilization, depending on how it is used. It also breaks down odor-causing substances, making it a powerful deodorizing agent.

Kiri is a device that sprays and fills an enclosed space with weakly acidic hypochlorous acid water, and workers enter the Kiri before entering the livestock barn to sterilize their entire body, thereby sterilizing bacteria, viruses, etc. and preventing them from being brought into the barn. It also prevents bacteria, viruses, etc. from being brought in when workers leave a contaminated barn, thereby preventing the spread of contamination. The spray time can be adjusted from 30 to 60 seconds to suit the environment.
Kiri is a device that cannot be found anywhere else, as our company has held patents (no. 6831033 and no. 7224744).

This device sprays weakly acidic hypochlorous acid water into a mist and then uses a fan to distribute the mist evenly throughout the space, disinfecting and deodorizing the space. It is primarily intended for use in enclosed spaces such as offices and workshops. Spray time can be controlled using humidity sensors, timers, and motion sensors.
Spraying directly onto vehicles at vehicle gates used to transport livestock and feed using a single-fluid nozzle prevents the introduction and removal of viruses, bacteria, and other contaminants.
Spraying around the barn and in the work aisles using a two-fluid nozzle can also prevent wild birds and animals from introducing viruses and bacteria into the barn. It can also reduce the odors unique to livestock barns. Spraying around manure treatment facilities can help prevent odors in the neighborhood. Spray time and intervals can be controlled to suit the environment and season.
