Изобретение относитс к способам термического обеззараживани материалов, инфицированных патогенными микроорганизмами.The invention relates to methods of thermally disinfecting materials infected with pathogenic microorganisms.
Известные способы термического обеззараживани материалов, инфицированных патогенными микроорганизмами, осуществл ют нутем продувки автоклавов паром, герметизации аппарата, прогревани стерилизуемой среды до температуры инактивации и выдержки до полной инактивации микроорганизмов .The known methods of thermal disinfection of materials infected with pathogenic microorganisms are carried out by blowing steam autoclaves, sealing the apparatus, warming the sterilized medium to the inactivation temperature and holding it until the microorganisms are completely inactivated.
При этом прогревание в герметичном аппарате сопровождаетс ростом избыточного давлени , которое преп тствует свободному входу теплоносител (пара), снижа тем самым температурную интенсивность процесса.At the same time, heating in a sealed apparatus is accompanied by an increase in overpressure, which prevents the coolant (steam) from entering freely, thereby reducing the temperature intensity of the process.
Кроме того, обеззараживание сточных вод по известному способу может вызвать самопроизвольный выход непрогретых сточных вод под действием избыточного давлени через систему нередавливани и неплотности арматуры .In addition, the disinfection of wastewater by a known method can cause spontaneous outflow of unheated wastewater under the action of overpressure through the non-pressurized system and the looseness of the reinforcement.
В предлагаемом способе с целью повышени температурной интенсивности процесса и санитарно-гигиенической надежности перед обработкой перегретым паром обеззараживаемые материалы прогревают без подъема давлени до 90-100 С.In the proposed method, in order to increase the temperature intensity of the process and the hygienic reliability before processing with superheated steam, the disinfected materials are heated without increasing the pressure to 90-100 C.
Примечай и е: Давление пара в подвод щей сети - продувка автоклава паром - 15 мин в 4 ога, предварительна период прогрева.Note also: Steam pressure in the downstream network — blowing the autoclave with steam — 15 minutes in 4 hours, preheating period.
Способ термического обеззараживани материалов , инфицированных патогенными микроорганизмами , осуществл ют следующим образом .The method of thermal disinfection of materials infected with pathogenic microorganisms is carried out as follows.
Прогревают массу до 90-100° С при посто нном сообщении полости автоклава с атмосферой . При этом из-за отсутстви противодавлени на прот жении всего периода первой ступени истечение пара в прогреваемую массу происходит с критической скоростью и в большем количестве, чем при наличии избыточного давлени .The mass is heated to 90-100 ° С with constant communication of the cavity of the autoclave with the atmosphere. At the same time, due to the absence of back pressure throughout the entire period of the first stage, steam outflow into the heated mass occurs at a critical rate and in greater quantities than in the presence of excessive pressure.
По достижении температуры отрабатываемого материала - 100° С создают избыточное давление, обеспечива этим дальнейшее повышение температуры.Upon reaching the temperature of the material being processed - 100 ° C, they create an overpressure, thereby ensuring a further temperature increase.
Преимущества предлагаемого способа иллюстрируютс данными испытаний, приведенными в таблице.The advantages of the proposed method are illustrated by the test data given in the table.
Предмет изобретени Subject invention
Способ термического обеззараживани материалов , инфицированных патогенными микроорганизмами , Включающий обработку перегретым паром в автоклавах, отличающийс тем, что, с целью повышени температурной интенсивности процесса и санитарно-гигиенической наделшости, перед обработкой перегретым паром обеззараживаемые материалы прогревают без подъема давлени до 90-100° С.The method of thermal disinfection of materials infected with pathogenic microorganisms, Including treatment with superheated steam in autoclaves, characterized in that, in order to increase the temperature intensity of the process and sanitary hygiene, before treatment with superheated steam, the disinfected materials are heated without increasing the pressure to 90-100 ° C.
