DESCRIPTION:
BRIEF SUMMARY
This invention relates to edible products and their preparation, and to apparatus therefor.
It is known to produce ice confections by extrusion in variegated form, see for example GB Patent Specification No. 1,169,500 (National Dairy Products Corporation), which describes a variegator for ice cream which entwines streams of ice cream with each other before they are extruded from an extrusion outlet. In the apparatus described therein, the variegation arises purely within the body of the extruded product, as a result of the presence of two materials of different composition. On the other hand, a number of techniques are known for producing ice confections and other food products in shapes possessing complex relief features, e.g. by the use of flexible moulds, as in GB Patent Specification No. 1,508,589. Some of these techniques can be difficult to apply with reliability and economy, and it remains a problem to find ways to manufacture food products of decorative shape on an industrial scale.
It is the aim of the present invention to make and provide extruded ice confections with spirally-formed projections and recessed relief features of their outer surface.
According to the invention this can be done by using a process for preparing an extruded ice confection with spirally-formed projecting and relatively recessed relief features of its outer surface, comprising extruding the ice confection material from a rotating extrusion nozzle having a cross-section with an assymmetrical configuration with respect to the rotation axis, with the extruded confection passing from the nozzle immediately into an unconfined space and on to an elongate travelling conveyor which does not share the rotational motion of the extrusion nozzle, thereby to lay down on the conveyor an extended (elongate) spirally-formed extrudate with projecting and relatively recessed relief features derived from its extrusion through the nozzle of assymmetrical configuration.
"Assymmetrical configuration" of the extrusion nozzle cross-section means a configuration which is not bounded by a concentric circular nozzle outline. For example, such an assymmetrical configuration of the cross-section can be provided by one or a plurality of eccentrically disposed nozzle outlets, e.g. two or three or up to about six, each of which can have a plain circular sectional outline or an outline of another shape, e.g. indented circular or noncircular. If desired, there can be a concentric circular nozzle outlet among the array of nozzle outlets: e.g. such an array can comprise one concentric circular nozzle outlet flanked by one or a plurality of eccentric circular or noncircular nozzle outlets. Other examples are described below.
The rotating extrusion nozzle can thus have an indented or other non-circular shape so that a spiral indentation, rib, or other spirally-formed feature of shape is given to the extruded frozen product.
In this process, the spiral formation is caused by interaction between the material leaving the extrusion nozzle outlets and a takeoff conveyor, and as will be seen below, the process allows a wide variety of decoratively shaped products to be made by process control and adjustment of the variables introduced by this process, e.g. nozzle rotation speed, extrusion rate, nozzle height and inclination, and takeoff conveyor speed.
The effect of such process control features was not available with the previously known variegators, and products of the kinds made accessible to manufacture using the present process could not be made by their use.
In carrying out embodiments of the invention, a plurality of rotating nozzle can be used to produce more complex shapes. The nozzles can be fed with ice confections of different composition, flavour, or colour to produce further variegation in the product. The nozzles can for example rotate about the same axis or different axes at the same speed or at different speeds, and can rotate in the same or opposite direction of rotation.
