• step (e) the dough mixture is rolled into one or more sheets of a first thickness in step (e).
• the compacting of the sheets in step (f) can either be performed prior to or during baking.
• the sheets of a first thickness may be contacted using a rammer or a press, which supply a vertical old until the second thickness ranging between 60 and 87 % of the first thickness is reached.
• the compacting is required such that the device produced retains its shape during baking and increases the time in which the device becomes usable to engage either hot or cold comestible goods, in particular liquid comestible goods. Without the compacting, the consistency of the device would allow absorption of undesirable amounts of liquid leading to the device becoming soft and/or soggy prematurely.
• the sheets are subsequently placed into moulds corresponding to the shape of the device to be produced. Typically, the moulds are arranged in a tessellating fashion to optimise use of the compacted dough sheets and to avoid wastage. Notwithstanding, as the surplus sheet material can only be removed after baking, a certain amount of baked dough wastage is generated.
• the sheets of the first thickness are compacted during baking, they can be cut into blanks of the appropriate shape prior to being placed into the moulds and any dough sheet wastage can again be fed into the dough rolling of step (e) of the process.
• the cutting can be performed by an automatic cutter adapted to cut the sheets precisely into blanks matching according the shape of the mould, further minimising dough wastage.
• the blanks are then compacted by the application of a predetermined pressure ranging from 2000 to 3250 N/m 2 to the moulds during baking, i.e. are exposed to “compressed baking”. In either case, the sheets or the blanks are baked at a temperature ranging between 120 and 250°C. in addition, of the devices produced are then cooled in step (h), which preferably occurs naturally by placing the baked devices at room temperature, and are packaged for storage and/or sale in step (i).
• a further advantage of the process of the present invention described here is that it allows the production of edible devices for engaging comestible goods, which do not alter or influence the taste of the comestible good itself and/or do not produce an aftertaste. Notwithstanding, when the edible device is itself chewed for consumption, the device’s own taste is released.
• This advantageous feature of the devices produced by the process of the present invention allows flavouring of the device itself by adding flavouring agents as described above while at the further steps of the process ensure that the flavour is sealed into the device produced.
