Abstract:
For the shaping of ice cream bodies it is a simple and inexpensive technique to produce such bodies by extrusion of the ice cream mass through an extruder pipe and successively cutting off the bodies at the outlet of this pipe. However, cutting problems occur when the mass is of the type containing macro particles. With the invention these problems are counteracted by introducing into the string of extrusion mass flat cake bodies (20) of an extrusion mass, which does not contain macro particles, whereafter the cutting is carried out through the areas, in which this easier-to-cut mass has been introduced. Different methods for the introduction or formation of these layers are disclosed, and a borderline case (Fig. 5) is described in which the cutting is effected upon the macro particles being pressed into the surface of mass block to be cut off.
Abstract:
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.
Abstract:
In a cartonizing machine articles are arranged in groups in trays (8) passing along a feeding station further to and through a loading station (10), in which the articles on the successive trays are pushed transversely into respective carton members conveyed with a specific mutual spacing (P). The mutual spacing of the trays (8), therefore, should be correspondingly adapted. Normally this will imply that the trays are correspondingly spaced also in the feeding station. According to the invention the trays are much easier to fill when they are closely juxtaposed, this being achieved by means of a trayconveyor system disposed so as to operate with reduced tray pitch and tray speed in the feeding station.
