US 9,894,913 B2 · Filling unit and method for filling a confectionery product into a mould or a container

Abstract

A filling unit and a method for filling a confectionery mass into a container or a mold includes a fill housing with a filling nozzle (2) and at least two dosing pistons in a cylinder which is connected to the fill housing. In the fill housing, a valve is arranged for each cylinder. A mixing block with internal ducts connects each of the outlets with a respective internal duct in the filling nozzle. The confectionery mass is conducted from a filling nozzle into at least one of the cylinders after which the confectionery mass is dosed down into the mold or container by actuating the dosing pistons. The speeds of the pistons are controlled independently of each other, providing varying patterns in longitudinal direction of the ice-cream/confectionery product. The movement of the filling unit relative to the container or mold can be varied providing additional options for variation in patterns.

A filling unit for use in filling a confectionery product into containers, including a fill housing with a filling nozzle, at least two cylinders and a dosing piston in each of the at least two cylinders,

wherein, in the fill housing, a valve is arranged for each cylinder, in that each valve has a valve body with a first duct connecting in the filling nozzle for the confectionery product with the interior of one of the cylinders when the valve body is in a first position, and a second duct in the filling nozzle connecting another of the cylinders when the valve body is in a second position;
and
wherein a patterning block with internal ducts connects each of the valves with the respective one of the first and second duct in the filling nozzle.

A method for filling a confectionery mass into one of a container and a mould, wherein a filling unit is used which includes a fill housing with a filling nozzle and at least two dosing pistons, each dosing piston provided displaceably in a cylinder which is connected to the fill housing, and the filling nozzle having a plurality of individual ducts, each individual duct connected for receiving confectionary mass from at least a respective one of the cylinders via a patterning block;

the method comprising:
disposing the filling unit over one of a mould and a container;
moving the filling nozzle of the filling unit into one of the container and mould;
conducting a confectionery mass from a filling nozzle (6′, 6″) into at least one of the cylinders while the dosing piston in the cylinder (A) is retracted into the cylinder;
dosing confectionery mass down into one of the mould and container as the dosing pistons are activated and moved down into the cylinder (B), whereby confectionery mass is dosed from each cylinder down into one of the mould and container via the patterning block and via at least one of said individual ducts in the filling nozzle, as the dosing of confectionery mass from each cylinder is controlled in that the movement of each dosing piston is controlled independently of movements of the other dosing pistons;
and
actuating the filling unit such that the filling nozzle is drawn out of one of the mould and container during the dosing of the confectionery mass.
