A research team from the University of Samarra designs and manufactures a Disinfection tunnel by heat.

Under the guidance of the University of Samarra President, Prof. Dr. Sabah Allawi Khalaf, and supervised by the Dean of Applied Sciences College Assistant Professor Dr. Aiser Saleh Muhammad, a system has been designed:
Disinfection channel by heat
A device has been manufactured from the following basic components:
-A high-powered domestic air blower (plower)
-Two electric heater
– Electric board for controlling and organizing the mechanism of device work It contains (3 German Schneider contractors with a circuit breaker and a temperature sensor of Japanese origin Tokiko type)
– Sterilization cabin (channel) equipped with hot air push tubes with a temperature sensor. Dimensions (1.50m length x 1.50m width x height 220-210)
The sterilization principle depends on hot air instead of sterilization by sterilizers such as alcohol or chlorine, as the sterilization channel with alcohol spray supplied by sprays of alcohol, has harmful health effects on the respiratory system, as it causes allergy or pneumonia and asthma crises that may reach to suffocation and severe bronchitis may affect the eyes and skin as its effects from dehydration lead to the occurrence of eczema in some cases.
The sterilization channel regular alcohol mist also has economic effects as a result of consuming large quantities of alcohol in addition to the environmental impacts of keeping alcohol in the sterilization booth (the channel).
A single cough of a person infected with COVID-19 virus results in about three thousand fine mist droplets that may settle in the air, or on nearby surfaces or other clothes in contact with the infected person. Hence, the possibility of transmission from clothing to the person is very high as contact with hands-on clothes. The place of contamination with the virus is when the hand comes in touch with the mouth, eye, or nose by mistake, so the sterilization of people’s clothes who have contact with people with the virus is essential despite being very difficult. Thus the importance of using heat as a tool to sterilize the clothes has increased through the person passing through a channel provided a sizable hot air force can pump air temperature through the unit control, so this is an essential device in the entrances and exits of different institutions or hospitals.
Several studies indicated that the virus could be affected by the temperature very significantly, as Vincent Monster, head of the viral environment department at the Rocky Mountains laboratories, showed that the natural fibers of the clothing fabric might cause the virus to kill quickly at a temperature between 45-55 °C. The influence of the virus, due to the rapid and significant rise in temperature, is due to the infection is coated (covered with an oily outer membrane – known as the double lipid layer and protruding proteases from it), compared to other uncoated viruses.
The device designed and implemented with personal following-up and unlimited support from the President of the University for the research team consisting of:
1-. Dr. Aiser Saleh Mohammed / Dean of Applied Sciences College
2- Prof. Rafah Razouk Hamid / Head of Academic and Teaching Documentation Unit at the College of Education
3- Dr. Omar Thaer Jawad / teaching at Applied Sciences College
4- Ghufran Shehab / Instructor at Applied Sciences College
