Abstract

The invention relates to a method and a device for automatic milking cup intermediate disinfection, in particular in automated milking systems, by heat treatment after each milking. According to the invention, a milking cup receiving container located at each milking place is supplied with hot water via a ring line from a hot water tank. The teat cups are immersed in the teat cup storage container and a variably fixed temperature exposure time combination ensures a safe disinfecting effect. The hot water is fed down from the teat cup receiving container via a return line to the hot water tank. An initial and final rinsing takes place by briefly connecting the teat cup container to the feed line and / or the cold water line, removing the polluted pre-rinse water into the sewer line and returning the rinse water to the hot water tank via a return line.

Field of application of the invention

The invention relates to a method and a device for automatically performing the Melkbecherzwischendesinfektion by heat treatment after each Gemelk, especially in automated milking parlor systems.

Characteristic of the known state of the art The milking intermediate disinfection is as a necessary measure to suppress the pathogen transmission

contaminated milking cup required. It takes place as a dipping process and is mechanized in the milking carousel (through-grinding tanks), in other milking systems it must be done manually in buckets. The energizing effect is achieved with chemical disinfectants dissolved in water.

The disadvantage is that contamination of the raw milk with residues of this use solution is possible and a Wastewater contamination due to chemical residues occurs. But there are also known devices for program-controlled cleaning of the milk-carrying parts of the milking plant, which the Work steps Pre-wash, disinfect and rinse off automatically. Thus, in the US patent 4,572,105

proposed to clock the disinfection regime and first blow out the milk residues from the milking parlor by means of air rinsing, then to disinfect it chemically, rinse with cold water and finally to blow out the water residues from the milking parlor.

Disadvantage of said cleaning devices is that chemical additives to secure the cleaning and Disinfecting effect are used, whose residues are considered environmentally sustainable. In the Federal Republic patent 3,501,328 (analogous to US 4,702,197) is another device for cleaning a Melkanlago

described, which increases the cleaning and disinfecting effect through the use of heated detergent.

Disadvantage of said cleaning devices is that also chemical additives to secure the cleaning and Disinfecting effect are applied. In the FRG Patent 2,018,159 a device for cleaning milking is published. It is about a Washing machine to ensure it d ^; 3 Internal and external cleaning of the milking tools almost self-acting. On a

the receptacles receiving the milking units are connected via circulating pumping systems, which are used in spray nozzles for

Flushing and spraying the milking leads. This serves a liquid circuit to the inside · and another circuit for Exterior cleaning of the milking parlors.

The disadvantage of this device is that to achieve a sufficient cleaning effect chemical rinsing and disinfecting agents must be used.

Another disadvantage is that the milking container is manually equipped with the milking machines. The cleaning device is therefore not suitable for milking intermediate disinfection in automated milking parlors.

Object of the invention

The aim of the invention is to safely prevent the transmission of pathogens for udder infections from cow to cow by contaminated milking cups by means of a proper milking cup intermediate disinfection and thus to increase the udder health and the quality of the milk of dairy herds.

Explanation of the essence of the invention The technical problem underlying the invention is that the operations

- Pre-rinse the milking cups to remove the remains of milk and soiling

- Disinfect the inner and outer surfaces of the teat cups

- Rinse the milking cups to cool to body temperature

machine and program controlled after every milking and at every milking station.

According to the invention the object is achieved by hot water from a Heißvvasserbehälter each Melkplatz over a Supply line is fed into a teat cup receiving container. In this milking cup container takes place after

each milking the Melkbecherzwischendesinfektion by heat treatment, the teat cups in the

Tilting milking bucket holdings are dipped and the hot water up and down the teat cup holder

is discharged and fed through a return line to the hot water tank. About variable festzusetzende

Temperature-exposure-time combinations ensure safe disinfection effects. Another feature of the invention is that for pre- and Nuchspülung the teat cups a hot water or Cold water flushing takes place. The teat cup container is briefly with the flow line and / or a Cold water pipe connected. The dirty pre-rinsing water is discharged from the teat cup container into the sewer, the Rinse water is returned via the return line in the hot water tank. The inventive device for Implementation of the method is that each milking place is assigned a milking cup receiving container. This is

with a loop, which consists of a flow line and a return line and connected to a hot water tank.

Furthermore, the milking cup receiving container is associated with a cold water line. For the return of hot water and the discharge of spent water is the teat cup container a Rear and a sewer downstream. The return line is equipped with a filter. Another feature of the invention is that an inlet is attached to the teat cup receiving container, so

is designed so that the liquid enters the container inner wall to prevent splashing.

Another feature of the invention is that each milking cup receiving container is associated with an overflow bypass line. This prevents contamination by overflowing liquid and protects the milker from scalding. embodiment The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows Fig. 1: Scheme of the method and the device for automatic milking cup intermediate disinfection.

In a thermally insulated, equipped with thermostatically controlled heater 2 hot water tank 1 hot water is generated. This is brought into circulation by means of a hot water pump 3. The hot water pump 3 constantly presses the water heated at the target temperature via the supply line 4 to all the inlets of the teat cup receiving containers 10 and the excess amount of liquid passes back through the return line 6 after passage of a pressure regulating valve 7 into the hot water tank 1. Program-controlled valve switching activates and deactivates the individual milking stations in the circulation circuit for milking cup intermediate disinfection. Cold water is removed from the cold water line 5.

For pre-rinse, a hot water mixture of cold water from the cold water line 5 and hot water from the circulation circuit by opening the cold water and hot water inlet valve 8,9 to the teat cup receiving container 10 is used. After removing the milking the teat cups 11 are immersed in the teat cup receiving container 10. The pre-rinsing water is discharged by opening the drain valve 12 in the sewer line 17. For rinsing and preheating the teat cups a repeated brief opening of the hot water inlet and closing and opening the wastewater drain is appropriate. Thereafter circulates the hot water from the supply line 4 through the Melkbecheraufnahmebehälter 10 and the return line 14 with built-in filter 15 by natural gradient back into the hot water tank 1. After the time of action of the hot water on the teat cups 11 for germ killing the hot water inlet valve 9 is closed and after emptying the Melkbecheraufnahmeventils 10 the cold water inlet valve 8 for cooling the Melkbech r and refilling the fed into the sewer line 17 in the pre-rinse hot water, opened. The return valve 13 remains at the end until the beginning of the next cycle in the open position

 An overflow bypass 16 on each teat cup receptacle allows for a high level of safety.
