Device for changing the jet shape of free-flowing products
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 has an inlet allocated to the inflow area and an outlet allocated to the outflow area. Each inlet of a channel has a first cross sectional area. Each outlet of a channel has a second cross sectional area. In order to make it easy to adjust the shape and velocity profile of the filling jet, it is proposed that the second cross sectional area of at least one channel be larger than the first cross sectional area of this channel.
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
several channels through which to pass the free-flowing products, the several channels comprising at least a plurality of eccentric channels spaced apart from a middle axis of the device,
wherein each eccentric channel comprises an inlet allocated to the inflow area and an outlet allocated to the outflow area,
wherein each inlet of the eccentric channels has a first cross sectional area,
wherein each outlet of the eccentric channels has a second cross sectional area,
wherein a quotient comprised of the first cross sectional area and the second cross sectional area drops as a distance between the eccentric channels and the middle axis of the device rises,
wherein the inlets and outlets of the eccentric channels are arranged in a plane wherein the plane in which the inlets are arranged is parallel to the plane in which the outlets are arranged,
wherein the second cross sectional area of at least one eccentric channel is larger than the first cross sectional area of this eccentric channel, and
wherein the number of eccentric channels measures at least 50.
2. The device according to claim 1 , wherein the cross sectional area of at least one eccentric channel enlarges continuously and/or monotonously in the direction of flow.
3. The device according to claim 1 , wherein a quotient comprised of a sum of the first cross sectional areas for all eccentric channels and a sum of the second cross sectional areas for all eccentric channels ranges from 0.35 to 0.75.
4. The device according to claim 1 , wherein a quotient comprised of the first cross sectional area and second cross sectional area for each eccentric channel ranges from 0.35 to 0.75.
5. The device according to claim 1 , wherein the inlets and/or outlets of the eccentric channels are arranged in circular rings around the middle axis of the device.
6. The device according to claim 5 , wherein the quotient comprised of the first cross sectional area and second cross sectional area is identical for each eccentric channel of the same ring.
7. The device according to claim 6 , wherein the quotient comprised of the first cross sectional area and second cross sectional area for each eccentric channel drops as the distance between each ring and middle axis of the device rises.
8. The device according to claim 1 , wherein the inlets and/or outlets of the eccentric channels are arranged in a point-symmetrical or axially symmetrical manner.
9. The device according to claim 1 , wherein the eccentric channels are separated from each other in the area of the outlets of the eccentric channels by webs with a thickness of 0.3 mm or less.
10. The device according to claim 1 , wherein a middle axis of each eccentric channel is inclined by an angle of inclination relative to the middle axis of the device.
11. The device according to claim 10 , wherein the angle of inclination ranges between 1° and 6°.
12. 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 channels defined by the device, the several channels comprising at least a plurality of 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 each inlet of the eccentric channels has a first cross sectional area,
wherein each outlet of the eccentric channels has a second cross sectional area,
wherein a quotient comprised of the first cross sectional area and the second cross sectional area drops as a distance between the eccentric channels and the middle axis of the device rises,
wherein the inlets and outlets of the eccentric channel are arranged in a plane wherein the plane in which the inlets are arranged is parallel to the plane in which the outlets are arranged,
wherein the second cross sectional area of at least one eccentric channel is larger than the first cross sectional area of this eccentric channel, and
wherein the number of eccentric channels measures at least 50.
13. The method according to claim 12 , further comprising the step of aseptically filling the foodstuffs.
14. The device according to claim 1 , wherein the free-flowing products are foodstuffs.
