ABSTRACT:
In the manufacture of a foamed confection such as foamed chocolate, a confection in liquid form is mixed with carbon dioxide under pressure. The mixture is discharged from the depositor through annular outlet orifices which are opened and closed in turn by associated valves so that at any one time some of the orifices are discharging the mixture, and the number of orifices which are closed does not vary. Each annular orifice has a length which is not greater than its diameter. Each valve has an annular valve seat and a valve member movable into and out of engagement with the valve seat.
