Milk container and method for making a milk container - Mjölkbehällare och förfarande för att tillverka en mjölkbehällare.

The invention relates to a milk container having one or more milk supply pipes 5 and washing pipes. The invention also relates to a method of making such a milk container.

The milk is conveyed to the tank of the milk truck, usually by means of overpressure pumps on the farms or by the milk car pumps. Similarly, the milk is usually discharged from the tank by means of pumps. The milk is then treated in at least two pumps. This has 10 effects on milk quality as certain compounds of milk, such as protein and fat molecules, tend to be easily degraded during pumping. The use of pumps also poses a kind of hygiene problem as they must also be able to be washed efficiently to guarantee the quality of the milk.

Milk containers should be washed particularly well, as milk is a highly perishable food defect. As a result, hygiene requirements are particularly high, especially in countries where milk is used as a drink. As a result, milk storage tanks usually have washers to bring the washing water containing detergent to the tank as efficiently as possible. Container cleaning is usually done from the service level on top of the container. However, such an arrangement is laborious, susceptible to interference, and at the same time constitutes a safety hazard.

BACKGROUND OF THE INVENTION A milk processing apparatus has now been invented whereby the transfer of milk into a milk container can be made with a particularly high quality. To achieve this object, the invention Other features of the present invention include some preferred embodiments of the invention, and a method for making such a milk processing apparatus has now been invented.

The milk processing apparatus according to the invention has one or more milk transfer tubes with valves: V for transferring milk and one or more washing tubes for introducing the wash water into the container.

The milk container according to the invention has one or more pneumatic valves connected to a wash pipe for washing the pressurized air valves and one or more pneumatic pipes connected to a pressurized and / or pressurized air reservoir 2 118 for pressurizing to and / or from the reservoir, and for washing the compressed air pipeline and the compressed air valves, the wash water is led to the compressed air valve and / or compressed air pipeline by a washing pipe mounted at least in addition, one or more water separators are connected to separate the washing water from the compressed air.

Similarly, in the manufacturing method of the invention for washing the compressed air valve and / or the compressed air pipeline, a milk pipe is connected to the In addition, one or more water separators are connected to the compressed air pipeline to separate the washing water from the compressed air. In the milk container according to the invention, the milk transfer can be carried out with particular hygiene and at the same time with very little change in milk quality.

The milk does not come into direct contact with the pump and is thus not subject to mechanical stress. The milk container washing equipment is connected to the milk transfer equipment, which makes it easy to maintain a high hygienic quality. The equipment required in the arrangement 20 is relatively simple, whereby the treatment of the milk in the milk container of the invention is also economically advantageous. In accordance with the invention, *: ***; whereas, therefore, technically gentle collection of milk and efficient washing of the equipment and the separation of the washing water from the compressed air are possible,. thereby further improving and simplifying equipment maintenance and cleaning.

The milk container according to the invention can advantageously be attached to a milk collection vehicle »·· and / or to a car trailer.

... According to one object of the invention, one or more pressure equipment is connected to the pneumatic piping system to form vacuum and / or pressure. Preferably, one or more pressure fittings may also be connected to the compressed air piping • * **; · * to conduct compressed air. Preferably, for example, the milk-collecting vehicle has milk containers connected to: ***; the pressure equipment and the compressed air are conveyed from the milk collector truck to the milk tanks of the trailer via pressure connectors, eg a pressure hose.

According to one object of the invention, one or more milk containers are connected to the milk container and the wash water is led to the wash pipe via a wash water channel between the milk containers. According to one object of the invention, one or more milk containers are connected to the milk container and the compressed air is supplied to the pneumatic tube via a compressed air channel between the milk containers connected to each other. Both of these have advantages in terms of both the space used and the technical architecture of the equipment. Milk pick-up trucks and pick-up trailers are structurally simple.

According to one object of the invention, a portion of the wash pipe and / or the compressed air pipe is mounted substantially horizontally with respect to the upper surface of the tank on the upper side of the tank. Preferably, a portion of the wash pipe is within the compressed air pipe with its horizontal portion. This solution is capable of providing efficient cleaning of the compressed air piping. Preferably, the washing pipe extends in practice to the entire horizontal portion of the compressed air piping on the milk container, whereby the washing operation therein is highly effective. The wash pipe inside the compressed air pipe preferably has holes for its entire 15 parts. Preferably, the wash water exits this horizontal section directly to the water separator by means of a vertical pipe, which is also washed at the same time.

According to an object of the invention, a tank scrubber, a compressed air valve and a compressed air valve wash pipe are mounted on the upper part of the milk container and the milk transfer tube and the washing pipe have connecting elements such as a valve and / or a connector mounted on the lower part of the milk container. This makes the use of the milk container of the invention particularly efficient and safe, since there is no need for operation and maintenance. *** joke to get on the milk container. Also, any vapors released from the washing liquid do not cause problems when using the milk container.

According to an object of the invention, the pneumatic valve has a shut-off device and a shut-off flange with a shut-off spring. This prevents possible damage to the milk container in the case of overpressure / underpressure. The sealing spring succumbs to overpressure / underpressure and thus also prevents possible damage to the washer • and / or air • pipe.
