摘要:
A delivery unit for ice creams of the type including at least a first piston pump supplied by at least one ice cream producing assembly, wherein the cylinder of the piston pump, in the portion corresponding to the end part of the supply stroke of the piston, is connected through a radial port to the delivery side of at least one second pump. Said second pump sucks a flowing ice cream garnishing material from a suction conduit controlled by a check valve, the sucking operation taking place when the first pump is in a position in which its piston obstructs the radial port, the piston stroke of the second pump being controlled, during the sucking operation, against the action of a counteracting device.

摘要:
An extrusion nozzle for manufacturing in a continuous flow process a variety of external shapes of frozen confections of the like. A portion of the periphery of the extrusion nozzle orifice is formed of a flexible deformable wall material, the shape of this wall being controlled by the state of actuation of a series of air cylinders which indent it when actuated. Individual internal features or an array of internal features may be moved to different lateral positions during manufacture.
