Abstract

A device for changing the jet shape of free-flowing products, in particular of foodstuffs, including: an inflow area for the free-flowing products to enter, an outflow area for the free-flowing products to exit, and several channels through which to pass the free-flowing products. Each channel includes an inlet allocated to the inflow area and an outlet allocated to the outflow area. The inlets together form an inflow surface with a width and height lying in the inflow area. The outlets together form an outflow surface with a width and height lying in the outflow area. In order to reduce splashing when filling packagings with a non-rotationally symmetrical cross section, the outflow surface is non-rotationally symmetrical.

First claim

The invention claimed is:

1. A device for changing the jet shape of free-flowing products, comprising:
an inflow area for the free-flowing products to enter,
an outflow area for the free-flowing products to exit, and
a plurality of eccentric channels through which to pass the free-flowing products,
wherein each eccentric channel comprises an inlet allocated to the inflow area and an outlet allocated to the outflow area,
wherein the inlets together form an inflow surface with a width and height lying in the inflow area,
wherein the outlets together form an outflow surface with a width and height lying in the outflow area,
wherein the inlet of each eccentric channel comprises a first cross sectional area, and the outlet of each eccentric channel comprises a second cross sectional area, and
wherein the second cross sectional area of at least one eccentric channel is larger than the first cross sectional area of this eccentric channel,
wherein the number of eccentric channels ranges between 30 and 50 and that the outflow surface is non-rotationally symmetrical, and
wherein an angle of inclination for each eccentric channel rises as a distance between the eccentric channels and a middle axis of the device increases.

2. The device according to claim 1 , wherein the height of the outflow surface is greater than the width of the outflow surface.

3. The device according to claim 1 , wherein the height of the outflow surface is at least 1.3 times greater than the width of the outflow surface.

4. The device according to claim 1 , wherein the height of the inflow surface is greater than the width of the inflow surface.

5. The device according to claim 1 , wherein the height of the inflow surface is at least 1.3 times greater than the width of the inflow surface.

6. The device according to claim 1 , wherein the inlets and/or outlets of the eccentric channels are arranged in a plane.

7. The device according to claim 1 , wherein the inlets and/or outlets of the eccentric channels are circularly arranged on rings around a middle axis of the device.

8. The device according to claim 7 , wherein the inlets and/or outlets on an outermost ring are arranged in two opposing and separated groups.

9. The device according to claim 7 , wherein a middle axis of each eccentric channel is inclined by the angle of inclination relative to the middle axis of the device.

10. The device according to claim 9 , wherein the angle of inclination ranges between 1° and 6°.

11. The device according to claim 1 , wherein the angle of inclination measures about 0°.

12. The device according to claim 1 , wherein a quotient comprised of the first cross sectional area and second cross sectional area for each channel ranges from 0.35 to 0.75.

13. A method for filling foodstuffs comprising the steps of:
directing foodstuffs to an inflow area of a device for changing a jet shape of the foodstuffs,
passing the foodstuffs through several eccentric channels defined by the device, the eccentric channels spaced apart from a middle axis of the device, and
directing the foodstuffs to an outflow area of the device,
wherein each eccentric channel comprises an inlet allocated to the inflow area and an outlet allocated to the outflow area,
wherein the inlets together form an inflow surface with a width and height lying in the inflow area,
wherein the outlets together form an outflow surface with a width and height lying in the outflow area,
wherein the inlet of each eccentric channel comprises a first cross sectional area, and the outlet of each eccentric channel comprises a second cross sectional area, and
wherein the second cross sectional area of at least one eccentric channel is larger than the first cross sectional area of this eccentric channel,
wherein the number of eccentric channels ranges between 30 and 50 and that the outflow surface is non-rotationally symmetrical, and
wherein an angle of inclination for each eccentric channel rises as a distance between the eccentric channels and a middle axis of the device increases.

14. The method according to claim 13 , wherein the foodstuffs are aseptically filled.

15. The device according to claim 1 , wherein the free-flowing products are foodstuffs.

16. The device according to claim 3 , wherein the height of the outflow surface is at least 1.4 times greater than the width of the outflow surface.

17. The device according to claim 5 , wherein the height of the inflow surface is at least 1.4 times greater than the width of the inflow surface.
