1one

Изобретение относитс к микробиологической промышленности, а именно к апнаратам дл выращивани Шкpoopганизмов .FIELD OF THE INVENTION The invention relates to the microbiological industry, namely to apnarats for the cultivation of chemicals.

Известен аппарат дл выращивани микроорганизмов, содержащий емкость, диффузор и мешалку, расположенную под ним 11.A known apparatus for growing microorganisms, comprising a container, a diffuser and a stirrer, located under it 11.

Недостаток аппарата - отсутствие возможности стерилизации воздуха, используемого дл аэрации культурапьной среды и самой среды.The disadvantage of the apparatus is the absence of the possibility of sterilizing the air used to aerate the culture medium and the medium itself.

Наиболее близким к предлагаемому вл етс аппарат дл выращивани микроорганизмов , содержащий вертикальную емкость, дибфузор с теплообменной рубашкой и аэратор 2}.Closest to the present invention is an apparatus for growing microorganisms containing a vertical tank, a dibfuser with a heat exchange jacket and an aerator 2}.

В аппарате имеетс стерилизатор воздуха в виде УФ-облучател .The apparatus has an air sterilizer in the form of a UV irradiator.

Недостатком вл етс отсутствие возможности стерилизации культуральной жидкости, что необходимо дл предотвращени инфицировани ее побочной микрофлорой.The disadvantage is the inability to sterilize the culture fluid, which is necessary to prevent infection with its side microflora.

Цель изобретени - улучшение,условий процесса выращщвани путем озонировани подаваемого воздуха.The purpose of the invention is to improve the conditions of the growing process by ozonating the supplied air.

Дл достижени цели в аппарате дл выращивани микроорганизмов, содержащем вертикальную емкость, диффузор с теплообменной рубашкой и аэратор,последний состоит из коаксиально установленной в диффузоре цилиндрической обечайки и размещенного по ее оси электрода, подключенных к высоковольтному источнику напр жени , при этом нижн кромка обечайки расположена выше нижней кромки диффузора, а нижний участок электрода расположен между этими кромками, причем под диффузором установлена мешалка.To achieve the goal in a microorganism growing apparatus containing a vertical tank, a diffuser with a heat exchange jacket and an aerator, the latter consists of a cylindrical shell installed coaxially in the diffuser and an electrode placed along its axis connected to a high voltage source of voltage, with the lower edge of the shell above the lower edge of the diffuser, and the lower portion of the electrode is located between these edges, with the stirrer installed under the diffuser.

Бокова поверхность электрода покрыта диэлектриком.The side surface of the electrode is covered with dielectric.

На чертеже изображен аппарат дл выращивани микроорганизмов.The drawing shows an apparatus for growing microorganisms.

Claims

The apparatus consists of a vertical tank 1 with nozzles 2 and 3 for the input and output of the culture medium. 3897 In the tank 1 is placed a diffuser 4 with a heat exchange jacket, attached to the cracker 5, made of a dielectric material. The aerator consists of a shell 6 coaxially mounted in the diffuser 4 and an electrode 7 placed along its axis, the side surface of which is covered with a dielectric. Shell 6 and electrode 7 are connected to a high-voltage source. 8. In addition, valve 9 is mounted in cover 5 for gas exchange and sealing of container 1. In bottom of container 1, under the diffuser 4, is mounted a rod 10, driven by an electric motor 11. Lower edge shell 6 is located above the lower edge of the diffuser 4, and the lower portion of the electrode 7 is located between these edges of the shell 6. The device works as follows. The culture medium is poured into the tank 1 so that its level is above the upper end of the diffuser 4. The motor 11 is turned on, which causes the mixer 10 to rotate. The rpm of the agitator 1 is selected so that the level of the culture medium inside the tank 1 drops below the end of the electrode 7. Then the high-voltage supply 8 is turned on and the air sucked through the shell 6 into the container 1 is ozonized, followed by dispersion into the liquid. At the end of the liquid sterilization, the revolutions of the mixer 10 decrease until the liquid reaches the end of the electrode 7. Then the high-voltage power supply 8 is turned off, the air ozonization process is stopped and the aeration of the liquid is carried out with ordinary air. Due to the fact that the culture medium 4 and is absorbed into the inside of the diffuser 4, the foam formed during the absorption also absorbs foam, which improves the process of defoaming. The apparatus allows the sterilization of air and culture medium without the use of additional facilities and makes it possible to combat infection by wild microflora of the culture medium in the process of growing the main culture, Claim 1. Micro-organisms growing apparatus containing a vertical container, a diffuser with a heat exchange jacket and an aerator, characterized in that, in order to improve the conditions of the growing process by ozonating the supplied air, the aerator consists of coaxially installed in the diffuser of a cylindrical shell and an electrode placed along its axis, connected to a high-voltage source of voltage, the lower edge of the shell is located above the lower edge of the diffuser, and the lower part of the electrode is located between these edges, and the agitator is installed under the diffuser. 2. An apparatus according to claim 1, characterized in that the side surface of the electrode is covered with a dielectric. Sources of information taken into account during expeutitis 1.
