Abstract:
The present invention relates to a milking method in which at least one teat cup is connected to a teat of the animal to be milked and milked milk is discharged from the teat cup, and in which upon cessation of the flow of milked milk a cleaning medium is passed via a supply line into the teat cup. Furthermore, the present invention relates to an apparatus which is suited for carrying out the method and comprises at least one teat cup which communicates with a milk line conducting milked milk and in the interior of which a supply line ends via which cleaning medium which has been discharged from a source can be introduced into the teat cup. The present invention provides a method and an apparatus for preventing dirt and germs from penetrating into the milked milk with more reliability. According to the invention the cleaning medium as well as air introduced for discharging the milked milk are introduced via the supply line into the teat cup.
Abstract:
The present invention refers to a device for cleaning milking cups. Known devices of this type have a cleaning element which is adapted to be attached to a milking cup and which is adapted to be used for rinsing the milking-cup interior and for spraying rinsing liquid onto the end face of the milking cup so as to clean the outer surface thereof. The present invention provides an improved cleaning device comprising a cleaning element which is adapted to be attached to the milking cup such that a flow chamber is formed for producing a rinsing flow along an outer surface area of the milking cup which is to be cleaned. By means of this solution according to the present invention, an improved cleaning effect is achieved and the rinsing agent conducted through the flow chamber can then be used for cleaning the interior of the milking cup.
Abstract:
A valve for the reverse-flow flushing of teat cups in milking machinery has a housing with an interior and a channel to the atmosphere. The housing has three connections, a first connection for connecting with the teat cups, a second connection for connecting with the milk line and a third connection for connecting with the reverse-flow flush line. A disk is mounted for rotation in the interior of the housing and has channels permitting communication through the interior of the housing between the first and second connections and blocking the third connection when the disk is in the milking position, permitting communication through the interior of the housing between the first and third connections and blocking the second connection when the disk in the reverse-flow position and permitting communication through the interior of the housing between the first and second connections while blocking the third connection and the channel when the disk is in the rinsing position.
Abstract:
A modified milking machine claw having ferrules or connectors with an aperture in the surface of each ferrule to allow complete sanitation of milk lines and removal of debris from pockets between the ferrule and the tube lumen of short milk tubes.
Abstract:
A sink for washing tie-stall dairy farm milk pipeline systems includes a narrow trough at the bottom of the sink. The trough receives the inflations of milking machines placed in the sink for washing. The sides of the trough confine and constrain the inflations so that the machine does not tip over while in the sink. The water level remaining in the sink when the pipeline system is flushed through therefore can be small, leading to water savings of up to 30%. The trough is made from stainless steel sheets, bent to shape; the sides of the sink extend outwards and outwards from the trough at an angle, whereby the sink sides guide the inflations into the trough as the farmer lowers the milking machine into the sink.
Abstract:
The conventional method of cleaning the teat cups of a milking machine head is to immerse all of the heads in a single container of cleaning fluid. A simple, effective alternative is an open topped casing installed at each milking stall, the casing including a flat top plate, four wells dependent therefrom for receiving the teat cups individually, an inlet duct in the bottom center of each well, an H-shaped manifold for receiving cleaning fluid from a source thereof and for feeding the fluid to the wells, and an outlet in the bottom of each well near one side thereof for discharging cleaning fluid from the casing.
Abstract:
For washing a milker unit, the teat cups are inserted in respective flexible receivers which seal around the enlarged end portions of the teat cups and communicate with a distributor having an inlet connected to a vacuum line for washing liquid. During washing, a high vacuum in the milk pipe line raises a valve in the distributor, while closing a drain opening therefrom, and draws washing liquid through the distributor, the receivers, the teat cups therein, the milk claw connected to the teat cups, and then into the milk pipe line for washing the latter. After washing, atmospheric pressure prevailing in the milker unit and distributor allows the valve to drop to a position where excess washing liquid can drain through said opening. For milking, the teat cups are applied to the cow after removing them from the receivers, which are then stored by simply pushing them upwardly onto respective holders where they are automatically closed against entrance of dirt. During milking, the vacuum in the washing liquid line holds the valve against a seat to close the distributor inlet and prevent atmospheric air from entering the vacuum system. To remove the stored washing unit for a washing operation, the receivers are simply pulled down to release them from their holders.
Abstract:
A backwash valve for connection between teat cup assembly and milk manifold is illustrated. The valve includes a milk inlet, a central valve chamber and a milk outlet. The milk inlet communicates to the teat cup assembly. The milk outlet communicates to the milk receiving manifold, which manifold is typically under a vacuum. A valve head reciprocates through the central chamber into and out of sealing contact with the milk outlet. The valve head and valve seat reciprocate out of the central valve chamber to an isolation chamber during backwash. Any leak between valve head and valve seal sees the vacuum. By reciprocation of the valve seat to the isolation chamber, vacuum communicated to the milk outlet does not expose contaminates present in the backwash solution to leakage through the seal. Backwash fluid is introduced through a chamber communicated to the valve head and passes out into the central valve chamber. Thereafter the backwash fluid flows out the milk inlet and teat cup assembly along a reverse flow path. When cleaning is completed, the valve head reciprocates upwardly and the attached teat cup assembly discharges milk through the milk inlet, central valve chamber and milk outlet. A cleaning disposition is disclosed wherein the isolation chamber is placed in a flow path with cleansing fluid following the path. During this cleaning disposition, substantially all operatively portions of the valve are cleansed and purged by the cleaning solution after milking has terminated.
