Abstract: The invention comprises a slat conveyor for handling ice cream products (6) which are immersed for some time in processing vessels. Each slat (9) in the conveyor consists of an upper part (33) supported at a fixed height in the frame (40) of the machine and a lower part (34) that may be lifted and lowered by means of a lifting beam (41). The lower part (34) of the slat is supported by individually coupling and uncoupling means (44, 48). The means (44) are connected with the lifting beam (41) and the means (48) are connected with the frame. By activating and deactivating the means (44, 48) together with the lifting beam (41) it is possible to keep the products (6) in a raised position or in a lowered position throughout one or more successive operations. Hereby the process period may easily be varied and the slat conveyor can readily be adapted to different products just by changing the programming of the control unit for the coupling means (44, 48) and the lifting beam (41).

Abstract: A dispenser (1) for filling containers with confectionery such as ice cream includes a plurality of filler nozzles (2) with inlet openings (27, 28) and nozzle tips (3, 7), in each filler nozzle including a filler piston (9) displaceable in a filler housing (10). The filler housing and the filler piston are produced from a stainless steel with a treatment so that these surfaces can move together without tearing and at the same time are produced with such tolerances that the gap formed between the piston and the housing is impermeable to the confectionery but not impermeable to liquid. A hose/pipe arrangement (40) for detergent is connectable with the inlet openings (27, 28) and the nozzle tips (37) for flushing and cleaning, the detergent passing through the gap between the piston (9) and the housing (10) to exit through a hollow space (50) and be flushed by the detergent introduced from at least one nozzle tip (37). Owing to this, complete flushing/cleaning of the nozzle arrangement (1) is obtained.

Abstract: A metal mould for making a frozen confectionery product is made of a titanium-containing materials, the mould being produced by cold-working a sheet-formed blank, either by deep-drawing or by pressing two half shells which are subsequently welded together. By using titanium for the ice lolly moulds, it is possible to avoid the use of poisonous inhibitors, without any risk of corrosion on the moulds. There is a considerable risk of corrosion on the moulds as the moulds used in the production of frozen confectionery products are subjected to freezing baths with strong saline solutions. When using titanium material for making the metal moulds, it is further possible to perform stress-relieving annealing at a lower temperature than was formerly possible when the moulds were made of stainless steel.

Abstract: A plant for preparing over-run ice-cream includes a freezing apparatus for freezing mix supplied to the freezing apparatus via a feeding pump, an air supply apparatus for adding air to the mix before the mix is fed to the freezing apparatus, a mix mass flow meter for determining the mass flow rate of mix prior to addition of air, a computer which controls the air supply apparatus dependent upon the mix mass flow measured. The air is intimately mixed with the mix by means of a mixing apparatus arranged immediately before the freezing apparatus. The product in completely or partly melted condition has a cream-like thick consistency and an increased percent over-run.

Abstract: A freezing plant consists of a row of plate freezers (1, 2, 3, and 4), a feeding conveyor (5) and a removing conveyor (6). Each of the plate freezers (1, 2, 3, and 4) has a stack of freezing plates and means for stepwise lifting the stack in such a way that interspaces may be provided between the plates for filling and emptying the interspaces. Supporting means serve to support the at any time lowermost plate of the upper part of the stack at the upper limit of the interspace and releasable support means serve to support the at any time uppermost plate of the lowermost part of the stack at the lower limit of the interspace. The disengageable and releasable supporting means are adapted to release the stack for lowering the stack after positioning of the product to be frozen upon each freezing plate.

Abstract: A production apparatus comprises a step-wise driven conveyor adapted to receive articles to be subjected to different operations. Along the conveyor operative devices are arranged for carrying out the different operations to which the articles are to be subjected. The operative devices having comparatively short operation periods are stationarily arranged along the conveyor, whereas at least two operative devices having comparatively long operation periods, are movably arranged along the conveyor so as to follow the conveyor while the conveyor makes at least one step and then to be moved one such step opposite to the direction of movement of the conveyor. By such doubling of the operative device or devices having long operation periods, an increased capacity of the production apparatus is achieved. The production apparatus can be used in producing ice cream coronets.

Abstract: An apparatus for insertion of sticks into freezing pockets arranged row by row in a freezing machine comprises a conveyor having grooves for receiving the sticks and feeding the sticks to a number of predetermined positions. As the predetermined positions separate flicking devices are arranged for removing the sticks from the grooves positioned at the predetermined positions. The apparatus moreover comprises an insertion mechanism for inserting the sticks into a row of freezing pockets. In order to reduce stop periods in case the means for insertion of the sticks are blocked, the flicking devices are individually controllable.

Abstract: Ice lollies are frozen in two-parted moulds which are inserted in rows of freezing pockets in an ice lolly freezing machine. The moulds are thawed loose from the freezing pockets in which freezing has been carried out, are lifted out of the freezing pockets, separated for releasing the frozen ice lollies, assembled and inserted again into a row of freezing pockets. Before the moulds are lifted, a moderate heating of the freezing pockets is carried out sufficient for thawing loose the moulds with respect to the pockets. Then the moulds are lifted and moved to a position outside the area of such freezing pockets of such freezing machine. At the position the moulds are heated for thawing loose the ice lollies. Then the moulds are separated and the ice lollies removed while the moulds are positioned outside the area of the freezing pockets. Now the moulds are moved back to the area of the freezing pockets and are inserted into an empty row of freezing pockets.

Abstract: An apparatus for extraction of articles frozen in moulds in a freezing machine, comprises means for insertion of retaining means in the moulds for engagement with the articles. The apparatus further comprises means for lifting the retaining means for extraction of the articles. The retaining means for each mould comprise at least two plate sections adapted for insertion in a mould along the inner surfaces of two side walls of the latter facing each other. The plate sections ensure that the subject article is firmly gripped for extraction.

Abstract: In order to freeze articles in containers, the side of the containers against which the material to be frozen would normally contact is provided with a frozen coating consisting of a lining material having a lower melting temperature than the material to be frozen. The article, after being frozen in the container, may be easily removed from the container by heating the container to a temperature between the melting point of the lining material forming the coating and the material of the article such that the article will be loosened with respect to the container without any melting (or distortion) thereof.

Abstract: For converting a web of wrapping material from a U-shaped cross section into a tubular shape, an edge guiding mechanism is used having two edge engaging means which may be performed as suction means. Each of the suction means is supported by a pair of guiding rods converging from a forming means and towards a longitudinal welding means. When the suction means are moved along the rods, the suction means are moved towards one another. The suction means provide an engagement with the outer surface of the edges of the web of material and ensure the movement of the edges towards one another and towards the longitudinal welding means so that a web even of a thin and flexible material is securely engaged with the longitudinal welding means.

Abstract: An end reversing roller for a conveyor band of wire mesh is arranged at the delivery end of a freezing canal. The end reversing roller is provided with axially extending slats. The outer surfaces of the slats are spaced from the shaft of the reversing roller, a distance which is greater than the radius of the cylindrical surface which the wire mesh would otherwise follow. The outer surfaces of the slats will therefore engage the inner surface of the wire mesh whereby the wire mesh is caused to expand. Accordingly, relative movement occurs between the wire mesh and the material or the product which have been frozen in the freezing apparatus, and an effective breaking-off of the frozen material or the frozen product with respect to the wire mesh is effected.

Abstract: The invention relates to a complex column comprising a metallic core (1) embedded in a mass of concrete (2). This core (1) is accessible from the outside of the concrete mass (2) at each end of the column for its assembly to a structure.

Abstract: For picking up ice lollies which have been frozen in split moulds which are adapted to be inserted into rows of freezing pockets of an ice-lolly machine, an appartus is used comprising two rods. One of the rods is connected with one of the mould parts in each of the freezing pockets, and the other rod is connected with the other mould part in the freezing pocket. Means are arranged at the ends of each rod for engaging guiding means at a pick-up station. The guiding means are adapted for moving the rods away from each other after withdrawal of the lower moulds in question and for moving the rods towards each other after the ice lollies have been removed, and for inserting the moulds in the row of freezing pockets. The apparatus automaticizes the withdrawal and the insertion of the moulds in such a way that such withdrawal and insertion and the removal of the ice lollies may be carried out during the same working operation which is used by picking up ice lollies in normal automatic ice-lolly freezing machines.

Abstract: A freezing or cooling plant comprises an apparatus having an evaporator chamber. At the lower end the apparatus is connected with a feed conduit for liquid refrigerant and a suction conduit for suctioning refrigerant vapors. Both conduits communicate with a vessel in such a way that liquid refrigerant from the apparatus may flow to the vessel via both the conduits. By heating the apparatus due to washing of the outer surface of the evaporating chamber of the apparatus, only moderate pressure rises will occur in the apparatus since, after the cooling process is stopped, the apparatus will be emptied of liquid refrigerant and during the remaining washing period will contain solely superheated refrigerant vapors.

Abstract: At each end of a row of freezer plates for a vertical plate freezer, a cylinder with a piston rod is arranged. The two piston rods are connected with each other by means of a beam which extends below the row of freezer plates and the beam is connected with movable bottoms arranged in the spacings between the freezer plates. The frozen material arranged in the spacings is moved upwardly for removal by means of the cylinders arranged at the ends and free access to the spacings between the freezer plates is achieved along both sides of the row of freezer plates.

Abstract: A freezing or cooling plant comprises a compressor for compressing a refrigerant, and a condenser for condensing the refrigerant. Moreover, the plant comprises an apparatus to be cooled, e.g. a continuously driven ice cream freezing apparatus. An oil separator is connected with the lowermost part of the evaporator compartment of the apparatus by means of a pipe wherein a shut-off-valve is provided. If the risk should arise that the apparatus stops due to a too hard freezing of the material treated in the apparatus, the evaporator compartment may rapidly be emptied by opening the valve.

Abstract: An apparatus comprising elevator means for conveying carpet-formed flexible carriers in the vertical direction one about the other, an infeed station for inserting the carriers into the elevator means and an outlet station for removing the carriers from the elevator means, the carriers being mutually engageable at the outlet station and mutually disengageable at the infeed station and being controlled at the outlet station and at the inlet station by means of converging and diverging pairs of guideways which engage with sets of engagement means positioned at different levels at the front and trailing ends of each carrier.

Abstract: A method of transferring articles from a continuously moving feeding conveyor to a receiving conveyor whereby a reversing roller device, positioned within the delivery end of the feeding conveyor, is reciprocable with respect to the receiving end of the receiving conveyor in such a way that when the delivery of articles from the feeding conveyor is to be interrupted during a period of time, the velocity of the receiving conveyor is increased approximately simultaneously with the initiation of the forward movement of the reversing roller device but such that the receiving conveyor, during the period of time wherein delivery of articles from the feeding conveyor is interrupted, is moved a distance which is greater than the distance of total forward movement achieved by the reversing roller device, after which the velocity of the receiving conveyor is reduced to its original velocity and the reversing roller device is returned to its starting position.
