A new “Biomist” power disinfecting system |
D. J. ALWATTAR, Northland Labs., 1818 Skokie Blvd., Skokie, IL 60062 This patented invention provides a mobile and highly effective method of sanitizing food processing equipment and its operating environment. Its performance may be characterized as the power spraying of a disinfectant solution in a highly divided form by the use of a pressurized gas. The disinfectant solution is composed of concentrated alcohols combined with compatible buffers and adjuvants to achieve the desired sanitizing effect. Generally, the disinfecting solution is applied to surfaces by spraying in quantities of 70 to 80 ml per 25m³. This machine utilizes the pressure of the vaporization of liquefied carbon dioxide gas as a propellant to spray the disinfectant in a mixing ratio well below the lower explosion limit of alcohol. This mixing ratio is about 0.001 volume part (%) of the disinfectant to 100 volume parts of CO2 and is sprayed at a gauge pressure of 3-6kg/cm2. The use of a large quantity of CO2 gas fully eliminates the possibility of ignition or explosion regardless of the use of alcohol as the base of the disinfectant solution. Accordingly, the solution can be sprayed safely, even in places where there is the possibility of open flame, heat of fire or electrical spark. When sprayed by the Biomist machine, the disinfectant solution is atomized into ultra micro particles that diffuse uniformly into all the nooks and recesses that may be inaccessible to routine sanitation swabbing protocols. Further, the use of the Biomist power disinfecting method is highly effective against airborne pathogens when used in confined spaces such as clean rooms and food storage areas, while sanitizing surfaces efficiently and reliably in a short period of time.
