<p>In the production of extruded icecream bodies it is customary to cut the bodies from an extruded string of icecream when the latter, laying on a conveyor belt, has reached a ''medium frozen'' condition, whereafter the bodies are transferred to a faster moving conveyor, on which they are moved through a hard-freezing zone with a desired mutual spacing between the bodies. According to the invention several advantages are obtained by arranging for the extruded string (6) to run unbroken through a continuous freezing zone, when only constrictions or notches (12) have been provided in the string by transversely moved tool means (8, 20, 22) while the ice substance is still formable; after the hard-freezing of the string the single bodies (P) are separated from the string by a simple successive breaking action on the front end of the string, and the desired distance between the individual bodies can be produced by letting the bodies fall down onto a conveyor (18) moving at increased speed.</p> |
