Abstract
A method and system for producing extruded edible ice products wherein an extruded string is conveyed unbroken through a continuous freezing zone, with only constrictions or notches being provided in the string by transversely movable tools while the ice substance is still formable. After a hard freezing of the extruded string, single bodies are separated from the extruded string by a simple successive breaking action on a front end of the string, and a desired distance between individual severed bodies can be produced by permitting the bodies to fall onto a conveyor moving at a speed which is higher than a conveying speed of the extruded string.
Claims8
A method of producing extruded ice cream products the method comprising the steps of:
- delivering extruded material while still being deformable as an unbroken extruded string of ice material,
- conveying the extruded strings through a freezing zone,
- subjecting the extruded string after passing a first partial length of the freezing zone to a constriction formation mutually spaced positions corresponding to a desired length of the ice cream products without breaking the extruded string,
- further conveying the extruded string through a remaining length of the freezing zone so as to be hard frozen and into a severing station, and
- consecutively breaking off an intruding front end of the extruded string as a product body at a following construction area of the extruded string.
A system for providing extruded ice cream products, the system comprising:
- an extruder for extruding a string shaped extrusion product onto a conveyor belt passing through a freezing zone to a delivery position for hard frozen products severed from the string shaped extrusion product,
- means disposed adjacent the conveyor belt and spaced from a delivery end thereof for periodically forming a constriction in the string shaped extrusion product, and
- means disposed at a delivery end of the conveyor belt for consecutively breaking off a front end portion of the string shaped extrusion product at the respective constrictions.
