Definitions

  • the present invention relates to a method for producing extruded food products, in particular sweets, also referred to as "confectionery", from at least two partial mass flows from at least one extruder, which partial mass flows are fed to at least two inlets of a moulding device having at least one outlet, together forming a mass flow.
  • the invention also relates to a device for producing extruded food products.
  • extrusion processes are frequently used for producing products such as liquorice, sugar paste, fruit gum and chewing gum.
  • the ingredients for the product are fed to an extruder, in which the ingredients are compressed by a screw and/or heated, so that they are mixed and/or cooked, causing them to melt.
  • the material is subsequently pressed through an extrusion die under an elevated pressure, causing the product to take on the sectional shape of the extrusion die.
  • a product of this kind produced by means of the above process therefore consists of several bonded-together long strips having mutually different compositions, for example, after which cutting and possibly further processing of the products can take place.
  • the object of the present invention is to improve the above process and to provide a method for producing extruded food products having a highly varied appearance.
  • the method of the kind referred to in the introduction is characterised in that at least one of the partial mass flows to the outlet is alternately activated and deactivated, whilst the mass flow continues to flow uninterruptedly, such that the cross-sectional composition of the mass flow will vary in the extrusion direction.
  • the product manufactured by means of the known method consists of composite strips or partial mass flows, having a constant cross-sectional appearance along its entire length
  • the present invention makes it possible to manufacture a product having a composition that varies in longitudinal direction. This is achieved by activating and deactivating at least one partial mass flow to the outlet, so that the mass flow of the end product will vary. Since extrusion is a continuous process, those skilled in the art will appreciate that the mass flow that forms the product at the outlet cannot be interrupted.
  • the method according to the invention thus makes it possible to manufacture a product having a non-constant cross-section by using a continuous extrusion process, which was considered to be impossible to achieve by using the known method.
  • the obtained products can thus be given a surprising and varied appearance.
  • the activation and deactivation of the partial mass flows preferably takes place within the shortest possible time span so as to obtain a clear separation between two partial mass flows from a single outlet.
  • switching can also take place gradually, however, so that a transitional area between two successive partial mass flows is formed.
  • a partial mass flow to an outlet in a moulding device if a partial mass flow to an outlet in a moulding device is activated, other partial mass flows to said outlet will be deactivated.
  • a mass flow from a single outlet is composed of several partial mass flows, which partial mass flows form the mass flow of the products in series, as it were.
  • a switching device is to that end provided, which connects a respective one of the inlet channels for the partial mass flows to the outlet, with the various inlet channels for the partial mass flows being alternately connected by the switching device.
  • the second partial mass flow is deactivated when a first partial mass flow is activated.
  • the mass flow at the outlet now consists of the first partial mass flow.
  • the second partial mass flow is activated, whilst the first partial mass flow is deactivated; the mass flow at the outlet is now formed by the second partial mass flow. In this way a product that is striped in the longitudinal or extrusion direction is obtained.
  • the invention is not limited to a particular number of partial mass flows for forming a mass flow at the outlet. Although an example comprising two alternating partial mass flows has been described above, it is quite possible to engage several partial mass flows, depending on the desired appearance of the product .
  • the mass flow is formed by at least two partial mass flows from at least two outlets of the moulding device, with the partial mass flows to at least one of said outlets being alternately activated and deactivated.
  • Each of the partial mass flows that form the mass flow of products at the outlets can be switched according to the above-described process. It is possible in this regard to alternately activate or deactivate one of the partial mass flows and to maintain another partial mass flow constant or, for example, to activate/deactivate all the partial mass flows in alternation, forming a kind of chessboard pattern.
  • the individual partial mass flows from the outlets expand and bond together under the influence of a lower temperature and/or a pressure difference, for example, and form the mass flow of the product.
  • the individual partial mass flows are passed through an additional moulding die so as to form a single mass flow.
  • a partial mass flow to at least one outlet is alternately activated and deactivated, such that an alternately activated and deactivated mass flow is formed at said outlet.
  • said non-continuous mass flow bonds to, for example, a continuous mass flow from another outlet a product is obtained whose cross-sectional area varies in the extrusion direction.
  • a partial mass flow at at least one outlet is temporarily interrupted, as it were, by temporarily cutting off the supply of a partial mass flow.
  • the product formed as a result of the various partial mass flows bonding together at the outlet does lead to a continuous mass flow.
  • This can be achieved, for example, by having a partial mass flow at another outlet flow uninterruptedly, whilst the discontinuous partial mass flow of the other outlet bonds with the continuous mass flow.
  • It may also be possible, for example, to have two discontinuous partial mass bond together at the outlets, in which case the two partial mass flows are activated in such a manner as to overlap temporarily.
  • a partial mass flow is deactivated to a first outlet, said partial mass flow is activated to another outlet.
  • the partial mass flows can be supplied to the moulding device in a continuous mass flow, as said partial mass flows are continuously connected to at least one outlet, and preferably to constantly the same number of outlets, or at least such that the total output of a composition does not vary.
  • the output of at least one extruder may also be possible, however, to control the output of at least one extruder.
  • the output of the extruder is controlled in dependence on the supply of the partial mass flow from the extruder.
  • the mass flow formed by the partial mass flows at the outlet may not be constant, for example, because the activation and deactivation of the partial mass flows does not take place in phase. It may be advantageous in this regard to adapt the output of the extruder of the alternately deactivated mass flow in an alternating manner, since the mass cannot be retained in the moulding device indeterminately in the case of a temporary deactivation, especially not in the case of a large mass flow.
  • the activation and deactivation of a partial mass flow to an outlet comprises the passing and blocking, respectively, of a partial mass flow from the inlet to the outlet of the moulding device. Said blocking and passing may be done by means of valves, for example.
  • the activation and deactivation of a partial mass flow to an outlet comprises the rotating of a switching shaft disposed between the inlets and the outlet, in which switching shaft passages are formed, which passages, as a result of said rotation, connect different inlets to the outlet in an alternating manner.
  • the partial mass flow is able to flow from the inlet to the outlet.
  • another inlet of a partial mass flow is blocked in that case, since said inlet does not connect to a passage in the switching shaft. Further rotation of the switching shaft will place said second inlet into communication with a passage in the switching shaft and cause the first partial mass flow to be interrupted.
  • At least two partial mass flows are of different composition, the compositions preferably being mixed in separate mixing chambers. More preferably, the partial mass flows are different in colour and/or taste. Especially if the partial mass flows are different in colour, endless combinations of the patterns can be realised by means of the method according to the invention. Since the number of different partial mass flows is by no means limited, either, it would even be possible to form images in a product by co-ordinated activation and deactivation of the appropriate partial mass flows to an outlet.
  • At least two partial mass flows are supplied to at least two separate extruders.
  • the partial mass flows are of different composition, this is not necessary. It is also possible to create a mass flow from a single composition at the outlets, in which case the sectional area is varied by activating and deactivating the partial mass flows .
  • the invention also relates to a device for use in producing extruded food products, comprising at least two inlets for supplying partial mass flows and at least one outlet, wherein the device comprises a switching device for alternately activating and deactivating at least one of the partial mass flows to the outlet of the outlet channel.
  • the switching device is preferably arranged for switching between at least two inlet channels to a single outlet channel. It is advantageous in this regard if the switching device is connected to a central control unit, which is arranged for driving the switching device at predetermined points in time in dependence on the desiredpattern.
  • the device comprises several outlets, whilst each of the outlet channels of the outlets can be alternately connected to at least one inlet channel of the device.
  • the switching device comprises a rotary switching shaft, wherein the inlet channels and the outlet channel of the device extend up to the circumferential surface of the switching shaft, and wherein the switching shaft comprises at least one passage which extends up to said circumferential surface for alternately connecting at least one inlet channel to an outlet channel.
  • the inlet channels of a single outlet channel preferably extend concentrically in that case, being arranged for connecting to the at least one passage formed in the switching shaft in dependence on the angle of rotation of the switching shaft.
  • the switching device comprises one outlet channel for every inlet channel, with the inlet channel and the associated outlet channel extending in the same plane transversely to the axis of the rotary shaft. More preferably, the several outlet channels converge into a single outlet. It is advantageous in that regard if the switching shaft comprises a passage for each inlet channel of the device. For each outlet there is thus provided an inlet channel, a passage and an outlet channel for each composition, preferably from separate mixing chambers or extruders for forming the partial mass flow at the outlet. The outlet channels of a single outlet to that end converge into said one outlet.
  • the passages in the switching shaft and/or the inlet channels of the device extend in such a manner on the circumferential surface of the switching shaft that an outlet channel will continuously be connected to an inlet channel of the device during rotation of the shaft. In this way it is ensured that an uninterrupted mass flow is obtained at the outlet.

  • the inlet channel 71B is connected to the outlet channel 91B, it is preferable to shut off the inlet channel 71A from the outlet channel 91A.
  • the angle 12A at which the inlet channel 71A is blocked by the circumferential surface of the switching shaft 6 to that end corresponds to the angle 12B in figure 4A.
  • both angles are 90° ⁇ 90 B ??) , and the rotational speed of the switching shaft 6 in the direction I can be varied for the purpose of adapting the composition of the partial mass flow at the outlet 51 of the outlet channels 91B and 91A.

  • Each of the partial mass flows 31 and 32 may have been formed in the same manner as the individual mass flow 31 of the product shown in figure 5A. It is advantageous in this regard, however, that when the partial mass flow having composition B for the partial mass flow 31 is deactivated at point in time X, said partial mass flow is activated for the partial mass flow 32. In a similar manner, the partial mass flow having composition A is switched from the partial mass flow 32 to the partial mass flow 31 at point in time X.
  • compositions are reversed to partial mass flows 31 and 32 again.
  • the advantage of activating and deactivating the flows in phase in this manner is that the total mass flows of composition A and composition B will remain the same during the course of the process, since the mass flows 31 and 32 are switched in anti-phase.
  • the partial mass flows from the compartments or the extruders 2A and 2B can thus be kept constant .
  • Figure 5D shows a product whose cross-sectional area varies.
  • the partial mass flow 31A is formed from composition B and the partial mass flow 32 is initially formed from composition A.
  • the partial mass flow having composition A is deactivated, however, without a partial mass flow having composition B, for example, being activated, as a result of which no partial mass flow will be delivered to the outlet 52, for example, until the partial mass flow in question is reactivated at point in time XII.
  • FIG. 5F a product is shown which consists of four interconnected partial mass flows 31, 32, 33 and 34 made up of several compositions A, B, C, D, etc.
