Definitions

• Ice cream bodies may be formed in different manners, but most suitably by extrusion of an ice cream mass down towards a conveyor belt and cutting off from the mass the single bodies, which are then further conveyed as individual bodies along an associated belt conveyor or other receiver means.
• the extrusion string of the mass concerned is arranged to be prepared in a mann such that in this string there will occur transverse layers of pure ice cream mass at the places where the string will be cut.
• the cuttings can be effected without the cutting means meeting the macro particles otherwise present in the ice cream mass, so the cuts ma be fully clean despite the fact that the desired macro particles occur in the major part of the cut off bodies.
• this is achievable in more different manners, primarily by arranging for narr layers of the relevant mass without macro particles to inserted into or formed in the extrusion string and the effecting the cutting through these added and easily cuttable layers.
• the layers may be established by insertion of layers cut from an extrusion string of the easy-to-cut mass or by injection of this mass after a plough body that is forced through the particle holding mass.
• an alternating extrusion can be used, by which there is shifted between the respective masses at suitable intervals.
• a further possibility is to periodically introduce into the flow of particle holdin mass a net plate, which will let the viscid basic mass pass through, but hold back the micro particles until t the net plate is retracted, whereby the cuttable layer will be formed just behind the net plate.
• Fig. 1 is a schematic perspective view of an embodiment of an apparatus according to the invention
• Fig. 2 is a corresponding view of another embodiment
• Fig. 3 is a side view of a third embodiment
• Figs. 4-6 are corresponding views of further embodiments.
• a downwardly conducting extruder pipe supplies an ice cream string with admixed macro particles to a mouthing area just above a transverse, rotary disc 4, which is provided with throughholes 6 of a diameter corresponding to the inner diameter of the pipe 2.
• the disc 4 is rotatable on an underlying, rigid bottom plate 5 having a corresponding hole just beneath the pipe 2.
• a pipe 8 corresponding to the pipe 2 continues downwardly from the lower side of the bottom plate 5, down to a cutting station having a cutting wire 10 that can be moved across the lower pipe mouthing in a level somewhat above an underlying conveyo belt 12.
• the hole and the lower pipe act as a simpl extension of the extruder pipe 2, such that ice cream ca be pressed down and, by means of the wire 10, be cut intermittently for forming cut-off ice cream bodies 14, which are carried away on the conveyor 12 for further working, freezing or packaging. All this may take place without troubles if or when the ice cream substance is homogenous.
• the disc or turntable 4 When there are macro particles in the substance the disc or turntable 4 is taken in use, viz. in being turne a hole-step each time a portion corresponding to the desired thickness of the bodies 14 has been extruded.
• the holes 6 are moved through a filling mouthing 16 for homogenous ice cream substance supplied through a pipe 17.
• the hole By the turning out of a hol 6 from the pipe 2 the hole will bring along the layer o ice cream contained in that hole after the just stopped extrusion, and the disc 4 will close the mouthing of th pipe 2 until the next hole has been turned into positio underneath the pipe 2.
• This following hole contains a homogenous ice cream layer collected from the pipe mouthing 16, whereby this layer will simply substitute the layer that has just been removed from the continuou string of ice cream in the pipes 2 and 8.
• the latt layer is turned out it is brought to a rejecting statio 18, in which it is pressed out from the hole 6 through opening in the bottom' plate 5 for collection and recirculation and for making the hole ready for recepti of the next ice cream layer from the mouthing 16.
• the extrusion is continued until the ne working cycle of the disc 4, such that the ice cream string in the pipe 8 will be provided with a series of layers 20 of a homogenous ice cream mass with a pitch corresponding to the height of the bodies 14.
• the cutti by means of the wire 10 is controlled in such a manner that the cutting will be effected through the layers 20 themselves, such that no cutting will take place in the ice cream mass holding macro particles.
• the cutting wire can be moved through an inclined path, whereby it is possible to effect a straight cross-cutti during continuous extrusion.
• the method may be applied generally for the insertion of disc formations in the extrusion string, e.g. also discs of ice cream of a deviating colour or character. It will even be possible to introduce an additional disc portion midways in the bodies 14.
• Fig. 2 shows another embodiment, the parts of whic however, widely correspond to the parts of Fig. 1, such that corresponding reference numerals, now with and add " " can be used.
• the turndisc 4 of Fig. l is substituted by a reciprocal block 4 having a pair of holes 6 and 6 for cooperation with the mouthings of the respective pipes 2 , 8 and 17 , these pipes all being mounted against the underside of the bottom plate 5 .
• the holes 6 and 6" are both provided with pistons, 22 and 24, respectively, which are moved by suitable driving means such as cylinders 26 and 28 mounted on a rigid frame 30 on the block 4 .
• the block 4 will have its holes 6 and 6" corresponding with the pipes 8 and 2 , respectively, while in the opposite extreme position these holes will correspond with the pipes 17 and 8 , respectively.
• Fig. 3 illustrates a simple embodiment comprising two extruder pipes, here designated 2" and 17" debouchin into a common housing 32 having at the middle of its bottom an outlet pipe 8". Above the mouthing of the latter pipe there is provided a pivotable valve plate 34 by means of which it is possible to conduct material to the pipe 8" from either of the pipes 2" and 17". It will be readily understood that in this way it will be possible to provide for the same stratifications as in Fig. 1, while it is here possible to work with a variabl or adjustable layer thickness given by the holding time of the pivot valve plate in its respective outer positions, in combination with the flow through the pip 2" and 17".
• Fig. 4 it is shown that right across the extrud pipe 2 there may extend a plate 36 having one hole 38 corresponding to the pipe diameter and another, corresponding hole holding a net plate 40.
• the plate is reciprocable for switching ove between the two holes.
• the particle holding mass is free to pass to the lower end of the pipe 2; but when the net 40 is introduced, the particles will be held back, such that only the pure basic mass will pass, possibly with a certain content of fine particles that will cause no troubles at the final cutting.
• Fig. 4 is possible in this manner, by repeated switching over the plate 36, to produce particle free zones just as in Fig. 1, although with the tendency that the concentrati of the coarse particles becomes higher near the undersi of the discs that are finally cut off from the lower en of the pipe 2.
• Fig. 5 schematically shows an embodiment, in which the extruder pipe 2 conveys the the particle holding ma to a housing 43, in which a plough wing member 44 rotat in the direction of the arrow shown, this member having openings 45 in its rear side.
• the wing member is rotate from a shaft 46 and receives non-particle-holding extrusion mass through a conduit 47 in which there is provided a valve 48.
• This valve is opened each time the wing passes the area undrneath the pipe 2, whereby the wing displaces the particular mass and fills up after itself with the particlefree mass, such that also hereb there will be extruded stratified material through the pipe 8.
• the stratification will not be particularly sharp, but the particlefree layers may be sufficiently thick to ensure that there will be no macro particles in the cutting plane.
• Fig. 6 shows a practical embodiment which is nevertheless based on the same considerations.
• the extruder pipe 2 debouches into an opening 50 in a turntable 52, which may also be a reciprocating plate block, and the extruded, particle holding mass is thereb pressed against a fixed bottom plate 54.
• a turntable 52 which may also be a reciprocating plate block
• the extruded, particle holding mass is thereb pressed against a fixed bottom plate 54.
• the part 52 is then moved s as to bring the opening 50 to a position underneath a rejector piston 56.
• the said mass surface will additionally be ironed along the bottom plate 54, while the associated cutting out of the block member designated 58 in the opening 50 will be effected in a coarse manner at the top side of this block member, i.e. along the lower edge 60 of the pipe 2.
• the block member 58 will be self holding in the opening 50, and it will have a smooth bottom side and a somewhat rugged top side.
• the piston 56 is actuated to press t block member 58 down from the opening 50.
• the top side the block member will be smoothened by the very pressur of the piston, corresponding to an ironing, but normall in return, the block member will adhere rather strongly to the surface of the piston.
• the handling has resulted in the above mentioned situation, in which the is created, adjacent to the piston surface, a - very th - layer, in which there are no through-going macro particles, and according to the invention it is thus a realistic possibility to effect a scraping or cutting o of the pressed down block member 58 with the use of a thin knife or a sutti'ng wire 10 that is brought to swee along the underside of the piston 56.
• the cutting tool will not have to cut through or substantially move any macro particles, so there will b no noticeable wear on the cutting tool, while the block members 58 will nevertheless be delivered with almost totally smoothened surfaces.
