Definitions

  • the present invention is in the field of milking animals, especially cows.
  • the present invention relates to a device for disinfecting milking components or components in milking technology and a method for disinfecting components in milking technology, such as e.g. for disinfecting a teat cup, a teat cleaning device, the milk line or a milking system.
  • the invention is described below with reference to the use in milking systems for milking cows, it should be pointed out that the invention can also be used in milking systems for other animals that deliver milk.
  • the invention is suitable for use on milking systems of cows, sheep, goats, horses, donkeys, camels, llamas and dromedaries, elk, reindeer and buffalo and other mammals.
  • Disinfect here means disinfecting the milking installation as a whole or individual components in milking technology with the aim of reducing the concentration of germs and pathogens. In particular, this also includes disinfecting individual or all milking components in order to kill germs, bacteria or the like or reduce their number.
  • Additional cleaning is useful, for example, if, for example, larger pieces of feces stick to an udder cleaning brush, since it may not be possible to achieve sterility by disinfection alone. In such a case, cleaning the udder cleaning brush makes sense. Subsequently or simultaneously, disinfection can reduce the bacterial load in the udder cleaning brush can be significantly reduced. The disinfection itself can then be carried out using a reasonable concentration of disinfectant and under other practical parameters (time, temperature, etc.). For these reasons, a distinction is made between cleaning and disinfection in the sense of this application, although both steps can also take place in a combined step.
  • a combined cleaning and disinfection process is often used, in which e.g. the milk-carrying parts of a milking system are cleaned and disinfected. Disinfection can take place simultaneously with the cleaning process.
  • the cleaning effect is e.g. achieved by a batch process in which individual drops of liquid are sent through the system in a batch process. This also has a mechanical cleaning effect.
  • the simultaneous or successive addition of cleaning agents (e.g. in the form of solvents) and disinfectants can be used to clean and disinfect the milking system. Disinfection can also take place at high temperatures (boiling water cleaning).
  • the object of the present invention is therefore to provide an apparatus and a method for cleaning milking components which offer better properties.
  • the device according to the invention is the subject of claim 1 and the method according to the invention is the subject of claim 25. Preferred developments are the subject of the dependent claims.
  • the device for disinfecting a milking component has at least one container for storing at least one basic disinfectant.
  • At least one processing device is provided with which a disinfectant which preferably contains chlorine dioxide can be produced from the at least one disinfectant base material by chemical reaction.
  • at least one line device is provided, by means of which the disinfectant can be brought into contact with at least one milking technology component directly after manufacture in order to disinfect the milking technology component.
  • a device according to the invention for milking an animal comprises at least one toy, at least one milk line, at least one vacuum line, at least one container for a basic disinfectant and at least one preparation device.
  • the preparation device is provided in order to produce, by chemical reaction, a disinfectant from at least one basic disinfectant, which preferably contains chlorine dioxide.
  • the disinfectant is suitable for disinfecting the device.
  • the device according to the invention preferably comprises at least one milking cup or teat cup.
  • the method according to the invention includes the step of processing the disinfectant from the at least one disinfectant base material, the disinfectant preferably containing chlorine dioxide. Then at least one milking component or one component in the milking technology is disinfected with the prepared disinfectant.
  • the device according to the invention and the method according to the invention have many advantages.
  • chlorine dioxide in an aqueous solution for disinfection has many advantages. Chlorine dioxide (CIO2) is already used successfully for swimming pool disinfection. However, since the finished solvent is unstable, it must not be transported, but must be produced on the spot. Compared to chlorine, chlorine dioxide has the advantage of a considerably higher oxidizing power (about 2.5 times). In addition, chlorine dioxide does not have some disadvantages associated with the use of chlorine, such as the problem of haloforms.
  • chlorine dioxide Another advantage of using chlorine dioxide is that the odor nuisance is reduced compared to the use of peracetic acid.
  • the biofilm is also reliably removed.
  • chlorine dioxide is not an organic substance significantly reduces the allergy potential. This is a very significant advantage over the peracetic acid that is commonly used.
  • chlorine dioxide does not form any toxic substances such as trihalomethanes, chlorophenols and chloramines.
  • a very significant advantage for the use of chlorine dioxide is that it is approved for the treatment and disinfection of drinking water.
  • peracetic acid requires safe handling and causes higher operating costs because it is a hazardous substance during transportation. If chlorine dioxide is produced locally, the transport costs are considerably lower, since usually only the disinfectant base material has to be transported. In addition, peracetic acid is an organic substance with allergy potential for humans and animals. Furthermore, biofilm, fats, mucus and deposits are not broken down, as is the case with chlorine dioxide.
  • chlorine dioxide offers considerable advantages.
  • Disinfection with chlorine dioxide also has great advantages over disinfection with boiling water, since considerable amounts of energy have to be used for heating. Since this is usually done electrically and the efficiency of the available electrical connection on distant farms is relatively low, it also takes a lot of time to heat up. Chlorine dioxide is available for disinfection however available with almost no time delay. Planning the daily routine can thus be more flexible.
  • a control device which brings together corresponding proportions of water and disinfectant base material, so that the disinfectant base material can react to the disinfectant.
  • the chlorine dioxide solution can e.g. be produced as described in e.g. is described in German patent application DE 195 18 464 A1. However, other devices and methods known in the prior art for producing a chlorine dioxide solution are also possible.
  • “essentially directly after production” is understood to mean production of the disinfectant which is oriented to demand. Consumption does not have to take place immediately, but an intermediate container or intermediate store for finished or enriched disinfectant can also be provided

Dip cups, foremilk cups and a robot arm, if present, can also be disinfected.
  • a disinfectant with chlorine dioxide can be used to disinfect the teat cleaning device.
  • the use of a disinfectant with chlorine dioxide is also preferred when cleaning the teats using the teat cleaning device.

  • This can be variable and can be determined, for example, by a device as is known from DE-A-199 01 241 for roughly positioning the milking cluster below the udder of a cow.
  • first and second guides 6, 8 shown in the exemplary embodiment according to FIG. 1 are conventional groove guides.
  • the drive takes place in each case via a drive motor, not shown here, whose drive wheel acts on the one hand on the carrier 2 and on the other hand on the rail 10.
  • the torque of the respective motors is monitored.
  • the corresponding signal is fed to an evaluation device, not shown here.
  • the brush 2 bumps from the starting position into the end position, for example, against the leg of a cow standing in the box 20, the torque of the drive motor can suddenly rise sharply, which the evaluation device recognizes. This acts on the drive motor in question in such a way that the motor is stopped and possibly driven in the opposite direction.
  • the brush moves back to the starting position and is disinfected with a disinfectant before the udder of the next animal is cleaned.
  • the disinfectant contains chlorine dioxide, which can only be stored for a limited time and must not be transported locally. For this reason, the disinfectant is manufactured on-site if necessary by simultaneously disinfecting the basic disinfectant in water. For this, e.g. Alkali and / or alkaline earth chlorite and a mixture of caroate and alkali chloride. It is also possible to dissolve alkali and / or alkaline earth chlorite and alkali metal perodisulfate in water. Production is also possible by dissolving alkali or alkaline earth chlorite and iron or aluminum salt in water or alkaline earth chlorite. With regard to the manufacture, reference is made, for example, to DE 195 18 464 A1 and there to column 1, line 1 to column 6, line 47 and in particular column 1, line 54 to 5, line 14.
  • the disinfectant is fed into the central axis of the brush and distributed over the entire brush via small holes, so that reliable disinfection takes place. It is then rinsed with pure water to rinse off the disinfectant and the brush is spun to dry.
  • the udder cleaning brush is heavily soiled after cleaning the udder, cleaning the brush is advisable.
  • the cleaning can be carried out by using cleaning agents which, for example, loosen or at least facilitate the adhering dirt. Possible to support the cleaning effect, for example by mechanical action on the brush. Simultaneously or subsequently, the disinfectant can be added, which significantly reduces the bacterial load causes.
  • FIG. 2 shows a milking device 40 according to the invention.
  • the milking device has teats or teat cups 41 which are connected to a collecting piece 43 via short milk hoses 42.
  • the outlet of the collecting piece 43 is connected to a milking line 47 via a milk hose 44.
  • a treatment device in the form of a reactor 60 is provided for disinfection.
  • the reactor 60 is connected to at least one container 61 which contains a basic disinfectant.
  • a control device 66 which is designed here as a computer.
  • the water for the aqueous solution of the disinfectant is removed from the water line 53 via line 52.
  • a temperature control station 51 serves to heat the water.
  • An intermediate storage 67 is arranged in order to (temporarily) store finished disinfectant. Therefore, the production of the chlorine dioxide solution in the example shown can take place continuously or over long periods of time at a relatively low level in order to be able to easily cover the peak demand. If necessary, production can also be increased.
  • the disinfectant reaches the milking hose 44 from the intermediate storage 67 via a line 65.
  • a blocking and guiding unit 45 is provided at the inlet. It is possible here to route the disinfectant solution to the milk collecting piece 43 and to the teat cups, or only (or at the same time) through the milk hose 44 to the milking line 47.
  • the teat cups can also be subjected to a full head rinse, e.g. are immersed in or connected to the disinfection container 68.
