Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing foam on a liquid, for example milk, filled in a container, in particular a collapsible box having an inner layer for sealing the upper opening. .

When a frothy liquid such as milk is filled into a container through a pipe opening above the liquid surface, rather than through a submerged inlet, bubbles are generated at the liquid surface when the container is filled.

Moreover, in the upper part of the container, the inner surface of the container wall, which forms a lid in the case of a folding box and which has a layer suitable for sealing for this purpose, is moistened.

Despite these disadvantages arising from the filling process, it is advantageous in results to fill the container through a tube located above the liquid level.

Unlike the guide hole that goes inside the container, the iron pipe can be fixed to the upper blade of the container, so there is no need for it to come into contact with the outside of the container.

This outside, contrary to the inside of the container, is not sterile.

SUMMARY OF THE INVENTION The object of the invention is to provide a device which does not introduce the disadvantageous side effects mentioned above when filling and sealing a container with a foaming liquid.

In the present invention, this problem has been solved by providing a funnel-shaped suction device equipped with a blow-off nozzle whose blow-out direction is directed toward external force.

In such a device, the air blown from the blowing nozzle blows away the inner side of the box wall, which is moistened with bubbles and droplets and has the above-mentioned layer, and collects the extraneous bubbles in the center.

The foam is thus sucked out of the funnel without any problems.

A suitable embodiment has the following features.

That is, the blowing nozzle consists of a hole in a tube connected to a pressurized air tube, and the iron tube extends along the edge of the funnel-shaped suction tube.

In order to obtain an even efficiency over the entire surface of the container wall, the cross section of the funnel-like suction device can be adapted to the internal cross section of the container.

If the cross section of the container is a line of force, the suction device is preferably constructed in the form of a pyramid.

The invention will now be explained with reference to schematic diagrams of embodiments.

The illustrated device is installed in a filling device with two passages.

For this purpose, the filling device has two parallel movable funnel-shaped suction devices 1, 2, which are fixed to a common movable arm 3.

The arm 3 is configured as a suction tube and is connected to a ventilator (not shown).

For said lifting and lowering, a controllable pressurized air cylinder 4 is provided.
use.

The suction devices 1, 2 are pyramid-shaped.

On its lower square edge there are tubes 5, 6 (which can rotate);
This has a large number of perforations 7 and 8 as a blow-off nozzle whose blow-out direction is directed by an external force.

The pipes 5 and 6 connect to the pressure air pipes 9 and 108.

After the containers 11, 12 have been filled with milk at a given station of the filling machine, they reach the device according to the invention by means of a conveyor.

As soon as they come to rest below the aspirators 1, 2, the pressurized air cylinder 4 lowers the aspirators 1, 2 into the containers 11, 12 to just above the liquid level.

The sterile air emerging from the blowing nozzle 7.8 then blows the container wall in its upper region (here, in particular in the closed area), focusing on the foam, so that the foam is blown into the blower 1, 2 (It is attracted by this.

After removing the liquid bubbles, the suction devices 1, 2 are pulled up again,
The container continues to be transported.

The blowing of pressurized air is interrupted while the suction device is pulled up and out of the container.

This is because droplet formation and solubilization do not occur again on the inner wall.

The pressurized air blown out from the perforations is sterile when filling with sterile milk to prevent contamination of the milk.
