An apparatus is disclosed for the production of frozen ice-cream mass with solid ingredients, which in the finished ice-cream mass will appear substantially as inclusions which distinguish themselves by flavour, appearance and/or consistency from the surrounding homogenous ice-cream mass. The appara
An apparatus is disclosed for the production of frozen ice-cream mass with solid ingredients, which in the finished ice-cream mass will appear substantially as inclusions which distinguish themselves by flavour, appearance and/or consistency from the surrounding homogenous ice-cream mass. The apparatus comprises a first through-flow freezer for cooling of a continuous flow of mass, and a second through-flow freezer for further cooling of the continuous flow of mass, where a mixing-in arrangement for the mixing of solid ingredients into the continuous flow of mass is inserted between the through-flow freezer and the second through-flow freezer. It is hereby achieved that the mixing-in of the solid ingredients takes place in the frozen ice-cream mass when this has a temperature between-3�� C. and-7�� C. at which the viscosity of the mass is low. In order to achieve this uniform distribution of the solid ingredients, it is an advantage that the second through-flow freezer comprises a freezing cylinder and a conveyor screw which comprises a plurality of screw flights, at least two of which extend over the inlet part of the longitudinal extent of the conveyor screw, and where the outer edges of the two screw flights extend at different radial distance from the longitudinal axis. There is hereby achieved a better induction to the second through-flow freezer, and the inlet pressure can be reduced, typically to 4-6 bar.

The invention claimed is: 1. Apparatus for production of ice-cream mass with solid ingredients, comprising: a first through-flow freezer for cooling of a continuous flow of mass to between-1�� C. and-10�� C. at an outlet of the first through-flow freezer, a second through-flow freezer for further c
The invention claimed is: 1. Apparatus for production of ice-cream mass with solid ingredients, comprising: a first through-flow freezer for cooling of a continuous flow of mass to between-1�� C. and-10�� C. at an outlet of the first through-flow freezer, a second through-flow freezer for further cooling of the continuous flow of mass, and a mixing-in arrangement for mixing of solid ingredients into the continuous flow of mass between the first through-flow freezer and the second through-flow freezer. 2. Apparatus according to claim 1, where the second through-flow freezer cools the mass to between-10�� C. and-20�� C. at an outlet of the second through-flow freezer. 3. Apparatus according to claim 1, where the mixing-in arrangement comprises a wing pump. 4. Apparatus according to claim 1, where the second through-flow freezer comprises a freezing cylinder with an inner, rotation-symmetrical freezing surface which is regularly scraped by rotation of a scraping arrangement. 5. Apparatus according to claim 4, where the scraping arrangement is a conveyor screw which comprises a plurality of screw flights, each of which extends in a helical path around a longitudinal axis, where at least two screw flights extend over the same part of the longitudinal extent of the conveyor screw, and wherein the outer edges of the two screw flights extend at a different radial distance from the longitudinal axis. 6. Apparatus according to claim 5, wherein the at least two screw flights extend over an inlet end part of the conveyor screw. 7. Apparatus according to claim 6, wherein at least three screw flights extend over the inlet end part of the conveyor screw, and where one of the at least three screw flights extends at a greater radial distance from the longitudinal axis than the at least two other screw flights. 8. Apparatus according to claim 7, wherein the at least two screw flights which extend at a smaller radial distance from the longitudinal axis extend from the inlet end and at a different longitudinal distance from the inlet end. 9. Apparatus according to claim 5, where a pitch of the screw flights at an inlet end of the conveyor screw is 0.9 to 1.4. 10. Apparatus according to claim 5, wherein a pitch of the screw flights decreases along a length of the conveyor screw to 0.7 to 1 at an outlet end of the conveyor screw. 11. Apparatus according to claim 5, wherein at all places along a length of the conveyor screw there is at least one screw flight which extends at a given greater radius, so that a whole of the inner wall of a cylindrical cavity in which the conveyor screw is placed is scraped by rotation of the conveyor screw. 12. Apparatus according to claim 11, wherein the screw flights which extend at a greater radial distance from the longitudinal axis extend discontinuously in the longitudinal direction, so that a peripherally extending opening exists between these screw flights at least at one position along the longitudinal direction. 13. Apparatus according to claim 12, wherein said opening or openings extend over 120�� to 240�� of the periphery. 14. Apparatus according to claim 5, wherein a second through-flow freezer comprises a driving element (W) which is arranged to drive the conveyor screw at a speed of from 10 to 50 revolutions per minute.
