Description
Improved Confectionery Processing Machine and Manufacturing Process
The present invention relates to a confectionery processing machine for dispensing an edible
material, such as chocolate, in a tionery manufacturing process.
Confectionery processing es for dispensing an edible material are known. For
instance, referring to Figure 1, a known confectionery processing e 10 is shown. The
machine 10 is a multi-nozzle tor and includes a hopper 20 for containing the chocolate
to be dispensed. The hopper 10 is attached to a dispensing unit 30 in order to dispense the
chocolate. The dispensing unit 30 comprises a piston unit 40 and a nozzle unit 50. The piston
unit 40 typically has a piston plate 42. The hopper 20 is arranged on one side of the piston
plate 42. A plurality of pistons 44 extend from the other side of the piston plate 42. Each
piston 44 is in fluid communication with the hopper 20. The nozzle unit 50 comprises a
plurality of nozzles 54 within which the pistons 44 are sealed. The piston unit 40 is ed to
be movable in a ocating manner relative to the nozzle unit 50. in use, as the piston unit
40 moves away from the nozzle unit 50 during an upstroke, chocolate contained in the hopper
is drawn into the nozzles 54 through the pistons 44. In a following down , in which the
piston unit 40 moves towards the nozzle unit 50, the chocolate that had previously been drawn
into the nozzles 54 is ejected through nozzle tips 56. The mass which is rged from the
nozzle tips 56 is then pressed or cast onto a surface or into a mould according to the
manufacturing process in order to form moulded or cast confectionery.
s modifications to the dispensing unit have been considered. For example,
W02008/141468 discusses in more detail the precise ion of a suitable dispensing unit;
it would be beneficial if a confectionery processing machine was provided that was capable of
matching plant output to demand and that would enable the confectionery processing machine
to be more adaptable in order to accommodate processing methods for new confection.
It is therefore an object of the present invention to overcome at least one of the above or other
disadvantages. it is a further aim to provide a confectionery processing machine that provides
greater adaptability and/or flexibility to the processing plant. The ing object and aim
should be read disjunctively with the object of at least providing the public with a useful
alternative
ing to the present invention there is provided a confectionery processing apparatus and
a method of ng a confectionery processing apparatus as set forth herein. Other features
of the invention will be apparent from the description which follows.
According to a first aspect of the present invention, there is provided a confectionery
sing machine. In particular, the invention es a confectionery processing
apparatus comprising a cooling station to cool a mould; wherein the cooling station is zonal
and arranged to cool a portion of the mould differently to at least another portion by means of a
manifold ejecting cool air over the mould, wherein the manifold is divided into multiple outlets,
with each outlet arranged to eject air over a ic part of the mould, and wherein the
temperature of the air of each outlet is individually controllable. In the exemplary
embodiments, the confectionery processing has a hopper attached to a dispensing unit. The
dispensing unit comprises a plurality of co—operating piston and nozzles. The hopper is
arranged to supply an edible al to the plurality of co-operating piston and nozzles. The
sing unit is arranged in order to dispense the edible material from the plurality of co-
operating piston and s. The confectionery processing machine is improved by providing
the hopper with at least two separate compartments. Here, each tment separately
provides edible material to a n of the plurality of pistons. Consequently, a more flexible
confectionery processing machine is provided because all the plurality of piston and s
are not provided from the same compartment.
In one particular exemplary embodiment, the hopper is divided into first and second separate
compartments by a dividing means. The dividing means may comprise at least one dividing
plate. A first ng plate may be fixed within the hopper. in this case, the hopper may be
ably mounted to the dispensing unit. Here, the confectionery processing machine
comprises a plurality of hoppers, with each hopper ed to provide an ative
configuration of the size of each compartment. Thus, the number of co-operating piston and
nozzles supplied by each compartment can be selected by replacing one hopper with an
alternative hopper. Additionally or alternatively to the tionery processing machine
having a fixed divider, the tionery sing machine may be provided with at least one
moveable divider. Here, the moveable divider separates a portion of the hopper in to first and
second compartments. The moveable divider is movable within the hopper in order to
selectively change the number of co-operating piston and nozzles that the first compartment is
in communication with. Here, the moveable divider seals to the hopper in order to separate
the n of the hopper into the at least two compartments.
The provision of a dividing means therefore enables the confectionery processing machine to
be easily adapted. For instance, the capacity of the confectionery processing machine can be
adapted to match the output demand of the processing plant by reducing or increasing the
number of compartments that are filled with edible material. Alternatively, the confectionery
processing machine can be used for new processing methods by, for instance, filling different
tments with different materials.
(followed by page 2a)
Consequently, in accordance with a second aspect of the present invention there is provided a
method of ng a confectionery processing plant. Here, the method comprises filling a
number of separate compartments for a first production cycle and subsequently filling a
different number of compartments or filling compartments with a different edible al for a
second production cycle.
[FOLLOWED BY PAGE 3]
According to a further aspect, there is provided a dispensing unit for a processing machine.
The dispensing unit comprises a piston unit and a nozzle unit. The piston unit and nozzle unit
are arranged to move relative to each other in order to dispense material from a hopper. The
hopper may be substantially in accordance with the previous aspects or may be any known
hopper. The piston unit comprises a plurality of pistons. The nozzle unit comprises a
corresponding plurality of s. The pistons and nozzles are arranged to co-operate in
order to dispense the material. The dispensing unit is improved because at least one of the
co-operating s and nozzles is configured to dispense a different volume to at least one
other co-operating piston and nozzle.
In one exemplary embodiment, the co-operating piston and nozzle is configured by altering the
volume of the nozzle. Additionally or alternatively, the volume may be configured by adjusting
the stroke length. Preferably, the configured volume is adjustable.
According to a further exemplary embodiment, a processing machine is ed having zonal
heating. Thus, different areas of a hopper and/or a dispensing unit may be heated
independently. The hopper and/or sing unit may be substantially in accordance with
previous aspects.
In a further exemplary embodiment, a processing plant and method is provided. The
processing plant es a sing e and a vibration station and/or a g
station. The vibration station and/or g n may be zonal. That is, the vibration station
may be configured advantageously to provide different vibration teristics to one
dispensed material than to another. Furthermore, the cooling stations may be configured
advantageously to provide different cooling characteristics to the different materials.
Consequently, a vibration station and/or cooling station are also provided. The cooling station
and vibration station may be used independently, in conjunction with each other and/or in
conjunction with a dispensing machine in accordance with previous aspects.
For a better understanding of the ion, and to show how embodiments of the same may
be carried into , reference will now be made, by way of example, to the accompanying
diagrammatic drawings in which:
Figure 1 shows an example of a prior art tionery sing machine;
Figure 2 shows a confectionery processing machine in accordance with a first embodiment;
2012/050637
Figure 3 shows a hopper for use with a confectionery processing machine in accordance with
a second ment.
Referring to Figure 2, a first embodiment of a confectionery processing machine 100 is shown.
The confectionery processing machine 100 comprises a hopper 120 and a dispensing unit
130. The hopper provides edible material to the dispensing unit in order for the dispensing unit
to dispense the edible al. Suitably, the edible material is confectionery such as
chocolate. The dispensing unit is a multi-nozzle depositor. That is, the dispensing unit has a
plurality of co-operating pistons and nozzles that are arranged to co-operate to se the
edible al. Each rating piston and nozzle is supplied by material from the hopper
120. The ity of co-operating pistons and nozzles are fixed with respect to each other and
arranged in the dispensing unit 130 in accordance with a given manufacturing plant. However,
typically the plurality of co-operating pistons and nozzles may be arranged in multiple rows.
For example, the plurality of co—operating pistons and nozzles may be ed in a grid like
pattern.
Suitably, as shown in Figure 2, the dispensing unit 130 comprises a piston unit 140 and a
nozzle unit 150 that are arranged to be moveable toward and away from each other in a
reciprocating up-stroke and down-stroke . The piston unit 140 has a ity of pistons
144. Each piston 144 is hollow and able to be arranged, in use, in fluid communication with
the hopper 120. Consequently, the edible material within the hopper is able to be drawn in to
each piston on an upstroke. Each piston co-operates with a nozzle 154 in the nozzle unit 150.
The dispensing unit 130 is arranged to dispense the edible material from each nozzle 154
during the down stroke.
Whilst the dispensing unit is described herein in relation to a piston and nozzle arrangement,
exemplary embodiments may be based on other known depositors and particularly those using
a piston arrangement such as a horizontal piston or rotary valve.
The hopper 120 forms a boundary that es all the plurality of co-operating pistons and
nozzles 144, 154. Suitably, the hopper is formed from side walls joined continuously about the
boundary. For instance, in the Figures, the hopper 120 is shown as being formed from four,
joined side walls 122. The hopper may include a bottom plate 124, here the bottom plate
es apertures that are arranged to be in alignment with the plurality of co—operating
pistons and nozzles and therefore provide the fluid communication between the nozzles and
hopper 120. Alternatively, the hopper is not provided with a bottom plate and the sidewalls are
sealed directly to the dispensing unit 130.
Advantageously, the hopper 120 includes a first dividing means 160. The dividing means 160
separates the hopper 120 in to a first compartment 162 and a second compartment 164.
Here, the first and second compartments are isolated from each other. That is, edible material
filled into one compartment cannot flow into the other tment. Each compartment 162,
164 is therefore in communication with only a portion of the ity of co-operating s
and nozzles. Consequently, the provision of a dividing means allows the confectionery
processing machine 100 to be adapted to suit new processes and to fit the output demand of
the plant. For instance, if the output demands a reduced , one of the compartments can
be left empty.
ly, the dividing means 160 is a dividing plate 166. The ng plate 166 es a
continuous barrier from one side of the hopper to the other and is sized accordingly. However,
in alternative embodiments discussed below, the dividing plate 166 may also extend between
the hopper and a second dividing plate or two further dividing plates. It will therefore be
appreciated that in order to achieve the required separation, the dividing plate 166 seals to the
hopper 120, That is, as shown in Figure 2, ends of the dividing plate 166 seal to the side walls
122 of the hopper. A bottom of the dividing plate 166 seals to the bottom plate 124, when
provided, or the dispensing unit 130 when not.
In the exemplary embodiment shown in Figure 2, the dividing plate 166 is arranged to be fixed
fast to the hopper 120. For instance, the dividing plate 166 may be integrally formed with the
side walls 122 or welded or joined using adhesive or the like. In this embodiment, in order for
the confectionery processing machine to be flexible, the hopper is attached to the dispensing
unit 130 using a quick release mechanism. Thus, because the hopper is easily removed from
the dispensing unit 130, the tionery processing machine may include multiple hoppers
120, with each hopper adapted to provide a different combination of compartment sizes and
ore a different proportion of co-operating piston and nozzles in ication with each
compartment. Consequently, the confectionery processing machine is able to be adapted by
swapping hoppers.
Referring to Figure 3, a hopper 220 in ance with an alternative exemplary embodiment
is shown. Here, the hopper 220 is substantially the same as the hopper 120 previously
bed. For instance, the hopper 220 provides a boundary for enclosing all the plurality of
rating piston and nozzles and may have side walls 222, continuously joined along the
boundary. A bottom plate 224 may or may not be provided as previously discussed. Again,
advantageously, a dividing means 260 is provided to separate the hopper 220 in to a first
compartment 262 and a second compartment 264.
In the alternative exemplary embodiment shown in Figure 3, the dividing plate 166 is moveable
within the hopper 220. Thus, although the hopper may also be attached to a dispensing unit
using a release mechanism so that flexibility is ed by replacing hoppers, the
hopper 220 is also able to be flexibly adapted by moving the dividing plate 166 within the
hopper 220. Here, the relevant sides of the dividing plate 166 may be ed with seals in
order to provide the required separation between the compartments. The seals may be stiff so
that they exert a force to maintain the dividing plate 166 in position. Here, the dividing plate
may be moveable by sliding the dividing plate within the hopper 220. However, onally, or
alternatively, one or more of the side walls 222 (and bottom plate 224, when present) may be
provided with channels (not shown) for receiving the dividing plate 266. The channels may be
slots formed in the walls 222 or may be channels provided by two parallel protrusions that
extend from the side walls 222. Where channels are provided, ls may be provided
between each row of apertures in the bottom plate 224, or n each row of co-operating
piston and nozzles.
Consequently, there is provided a confectionery processing machine having an improved
hopper 120, 220 that enables the confectionery processing machine to be adapted to suit
demand and new processing methods. ore, although the improved hopper 120, 220
has been described in relation to a dispensing unit, the hopper 120, 220 may be used to
improve other machines using a hopper.
rmore, herein the hopper 120, 220 has been described having a dividing means 160,
260 comprising a first ng plate. However, further configurations are envisaged wherein
the dividing means comprises a plurality of dividing plates. Here the plurality of dividing plates
may be fixed fast, moveable, or a combination thereof. Consequently, the hopper 120, 220 is
divided in to three or more separate compartments. For instance, the plurality of dividing
plates may be two dividing plates. Here, the two dividing plates may be arranged parallel to
each other and arranged to te the hopper at two spaced locations. However, as well as
the dividing plates extending between two sides of the hopper, dividing plates may extend
n a side of the hopper and a second dividing plate or even between two dividing plates.
The confectionery processing machine 100 has been described herein in relation to known
dispensing units 130. Here, the dispensing unit is designed to dispense substantially identical
s of material from each nozzle. However, one of the main advantages of the improved
hopper described herein is that the processing e is ble and allows different
material to be dispensed from nozzles of the same machine. For instance, a al having
no inclusions can be dispensed from one nozzle whilst from a different nozzle, a material
including inclusions can be dispensed. Since this can lead to materials of different density or
viscosity being dispensed, when used with known dispensing units, different masses of one
W0 2012/127241 PCT/G32012/050637
material may be deposited as compared to another. Consequently, in a further exemplary
embodiment there is described an improved dispensing unit for the processing machine.
Whilst the exemplary embodiment is described as being particularly suitable when used in
conjunction with the improved hoppers 120,220 to dispense different als from nozzles of
the same machine, it will be appreciated that the improved dispensing unit may equally be
used with known hoppers, for instance, if different masses of the same material are required to
be dispensed from s of the same processing machine.
According to exemplary embodiments, an ed dispensing unit 230 comprises a piston
unit 240 and a nozzle unit 250. The piston unit 240 co-operates with the nozzle unit 250 to
dispense al from the nozzle unit. The piston unit comprises a plurality of pistons 244
and the nozzle unit comprises a co-operating plurality of nozzles 254. The dispensing unit 230
is improved because the dispensing unit is configured so as to dispense a first volume from at
least one of the co-operating piston and nozzles and a second volume from at least one of the
other co-operating piston and nozzles, wherein the first volume is ent to the second. In
one alternative exemplary embodiment, the dispensing unit is configured to dispense ent
volumes by altering the volume of the nozzles 254 (see for example Figure 4). In another,
alternative exemplary ment, the dispensing unit is configured to dispense different
volumes by altering a stroke length of the piston and s (see for example Figure 5).
In the exemplary embodiment shown in Figure 4, the volume sed by one nozzle 254a is
different to that dispensed by another nozzle 254b by altering the size of the respective nozzle
254. That is, a piston stroke length (SL) remains constant for all the plurality of co-operating
piston and nozzles, but by altering the volume of the respective nozzles 254, different volumes
can be dispensed. Here, the ity of pistons 244 are held fast in a piston plate 242 so that
all the pistons move simultaneously and the plurality of s are held fast in a nozzle plate
252. A seal 256 is formed between each piston 244 and nozzle 254. As the piston plate
moves toward the nozzle plate, from a m to minimum separation, a volume is defined
by the difference between the two limits of the travel (e.g. the stroke length) and a cross—
sectional area of that stroke length. Thus, because the nozzle 254b has a larger cross-
sectional area than the nozzle 254a, a greater volume is dispensed.
In the exemplary embodiment shown in Figure 5, the volume dispensed by nozzle 254a is
different to that dispensed by nozzle 254b by altering the stroke length of the respective co-
operating piston and nozzle. That is, the volume of each of the plurality of co-operating piston
and nozzles remains nt, but the volume dispensed is varied by altering the stroke length
(e.g. a difference in the distance travelled by the seals 256a and 25Gb). As shown in Figure 5,
this may be ed by mounting the pistons 244 movably within the piston plate 242. Thus,
at least one piston is ed to move separately to another. For instance, one piston may
W0 2012/127241
be fixed fast to the piston plate 242 whilst another piston may be fixed to the piston plate 242
in a slip arrangement. Suitably, the slip arrangement is shown in Figure 5 as a slip means 260
that is ed to connect the piston 244b to the piston plate 242 so that the piston moves a
different ce than the piston plate. For instance, the piston 244b may be connected to the
piston plate 242 via a gearing. Thus linear movement of the piston plate relative to the nozzle
unit causes a nt of the respective piston 244 ing to the gear ratio connecting
the two. Alternatively, as shown in Figure 5, the slip means 260 may be a co-operating
l and protrusion. For instance, as shown, a channel 262 may be formed in the external
wall of the piston. The channel has an elongate length in the direction of movement of the
piston. For stability, it is preferable if two or more ls are provided or the channel 262
may be a reduced outer size such as a reduced diameter region. The protrusion is formed on
the other of the piston plate or piston, and is shown as a member 264 fixed fast to the piston
plate in Figure 5. However, the protrusion may also be integrally formed. To match the
channels, the protrusion may be a plurality of protrusions spaced around an aperture that
receives the piston or may be a d sized aperture such as reduced diameter.
Consequently, the linear extents of the channel provide stops against which the sion
abuts. Thus, on the down stroke, as the piston plate moves toward the nozzle plate, the piston
that is attached fast to the piston plate moves immediately, whereas the piston including the
slip means initially will not move as the protrusion 264 does not abut an extent of the channel
(eg. the protrusion moves within and relative to the channel). The piston ing the slip
means does not begin to move until the protrusion has moved the length of the channel and
abuts the lower extent. Thus the stroke length of the piston including the slip means is
reduced. On the up stroke, and in e, the protrusion moves relative to the l until it
reaches the upper limit. The length of each stroke can be controlled by the length of each
respective channel. It will be appreciated that because the pistons move differently to each
other, it may be necessary to connect each piston in a flexible way to the hopper. For instance
the hopper may be connected to each piston via a shaft that is moveably sealed to each
respective piston.
It will be iated that the change in dispensing volume n co-operating piston and
nozzles of the same processing machine may also be achieved by a combination of altering
the nozzle volume and stroke length.
Whilst the processing machine may be configured in a fixed arrangement of dispensing
volumes of each of the co—operating piston and nozzles, it is advantageous if the volumes
dispensed by each co-operating piston and nozzle is easily adjustable. This is because it
allows the processing machine to be adapted to match the required output of the processing
plant. It also allows the change over time to be reduced.
Consequently, whilst it is possible to alter the volume of each nozzle by providing the machine
with a different sized nozzle and matching sized piston, it is advantageous if, as shown in
Figure 4, each of the plurality of pistons is a nt size and the nozzle plate 252 includes a
plurality of substantially identical nozzle ing locations 270. Here, the attaching locations
allow each nozzle 254 to be arranged on the nozzle plate 252 in rating ement
with the pistons 244. Thus, e identical attaching locations 270 are used, each nozzle
size is able to be fitted to any position on the nozzle plate. The attaching locations 270 and
nozzles 254 include attaching means. The attaching means may be any suitable means such
as a screw or bayonet fixing or the alike. It will be appreciated that because the piston size
1O remains constant but the nozzle size may alter, a means 280 to alter the piston size at the seal
256 must also be provided. The means may be to replace the seal 256 with a seal of a
different external size. However, In Figure 4, the means 280 is suitably shown as a
replaceable collar 282. Here, a replaceable collar 282 is provided for each nozzle size so as
to adapt an end region of the piston to match the nozzle size. The replaceable collar may be
attached to the piston by any suitable releasable means such as a screw or bayonet fixing or
the alike.
Furthermore, whilst the slip means 260 for each piston may be fixed, it is preferable if the slip
means is adjustable. For example, as suitably shown in Figure 5, inserts 266 may be provided
for adjusting the length of each channel.
It will be appreciated that whilst the improved sing unit has been described above as
having first and second volumes, the co-operating piston and nozzle pairs may be divided in
to sets, with each set having a different size. Whilst, two sets may be ed, a ity of
sets may be provided, with each ured to dispense a different volume. Moreover, each
set may include one or more rating piston and nozzles. The sets may therefore be
d, when used with the improved hopper, to the separate compartments or each 00-
operating piston and nozzle may be independently configured to dispense a required volume.
Consequently, there is provided an improved dispensing unit or processing machine including
the dispensing unit, due to the ability to se different volumes form nozzles of the same
sing unit. Moreover, it is particularly advantageous when the dispensing unit is
adjustable as change over time and costs can be reduced and the output can be adapted to
match demand.
In a further exemplary embodiment, not shown, of the processing machine, heating means is
provided through the processing machine. For instance, the hopper may be heated or the
dispensing unit may be heated or both in order to maintain the material being dispensed at the
required processing temperature. The heating means is preferably zonal. That is, preferably,
the heating for one area is controllable independently of another. The heating zones may be
matched to the compartments of the improved hopper. Thus, when different materials are
dispensed from one machine, each material can be maintained at a preferred temperature,
whereas without zonal g a worse case g would need to be applied. Consequently,
water circulation ls and / or electrical heating elements may be formed throughout the
machine. In the case of water circulation channels, two or more separate channels may be
provided so that each channel es a zone. Thus different zones can be heated with
different fluid sources. In the case of electrical heating elements being used, thermo electric
heaters such as r ts can be used and controlled independently to achieve zonal
heating. Alternatively heating elements woven into fabric or joined with other conductive
als can be wrapped around portions of the machine.
The exemplary processing es described herein may be used in conjunction with
downstream processing equipment such as a vibration station and cooling station. The
vibration station es the mould in order to level off the dispensed material, remove
bubbles and ensure the material reaches the corner of the moulds etc. The cooling station
controls the g of the material. Here, when the improved hopper is used, it is again
preferable if one or both of the vibration station and cooling station are zonal in order to
independently control the vibration / cooling applied to each of the different materials.
For example, the exemplary processing machine may dispense each material into an
individual mould. At the vibration station, each individual mould may be clamped separately
and vibrated. Alternatively, different vibration may be applied to different zones of one mould
for instance by using ultra sonic vibration and applying separate ultrasonic probes to spaced
areas of the mould to apply the vibration. Alternatively, rather than zonal vibration a common
vibration profile may be used. The vibration e may be a worst case profile or a profile
may be configured so that the mould is vibrated using a single profile but different areas of the
mould see different amounts of vibration. Alternatively the mould may be adapted so that
different areas have different vibration characteristics.
Furthermore, each individual mould may be processed by a separate cooling station.
Alternatively, a single mould may be passed through a cooling station having zonal cooling.
For instance, a manifold ng cool air over the mould may be d into multiple outlets,
with each outlet arranged to eject air over a specific part of the mould. Here, the temperature
of the air of each outlet may be individually controllable.
Although preferred embodiment(s) of the present ion have been shown and described, it
will be iated by those skilled in the art that changes may be made without ing
from the scope of the invention as defined in the claims.
