Inventore designato: Stefano MARELLO Designated inventor: Stefano MARELLO
Depositata il: 10 aprile 2018 Filed on: 10 April 2018
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad una macchina dosatrice per la produzione di praline, intendendo con tale termine un prodotto dolciario avente un ripieno circondato da un rivestimento, ad esempio un ripieno di crema rivestito da cioccolato. The present invention refers to a dosing machine for the production of pralines, meaning by this term a confectionery product having a filling surrounded by a coating, for example a filling of cream covered with chocolate.
Macchine dosatrici note sono provviste di martinetti distinti per dosare separatamente ripieno e rivestimento, che vengono successivamente riuniti mediante piastre intermedie provviste di valvole e quindi colati in alveoli di forma desiderata ricavati in uno stampo. Known metering machines are provided with separate jacks for separately metering filling and coating, which are subsequently joined by means of intermediate plates provided with valves and then poured into cavities of the desired shape obtained in a mold.
Tali macchine note sono quindi alquanto complesse e richiedono inoltre un riallestimento radicale in occasione di ogni cambiamento di stampo, nonché lunghe operazioni di pulizia quando si cambiano i materiali costituenti rispettivamente il ripieno ed il rivestimento. Such known machines are therefore quite complex and furthermore require a radical rearrangement on the occasion of each mold change, as well as long cleaning operations when changing the materials constituting the filling and the coating respectively.
Uno scopo della presente invenzione è dunque quello di fornire una macchina esente dagli inconvenienti sopra menzionati di quelle note. An object of the present invention is therefore to provide a machine free from the aforementioned drawbacks of the known ones.
Secondo l’invenzione, tale scopo viene raggiunto grazie ad una macchina avente le caratteristiche richiamate in modo specifico nella rivendicazione 1 che segue. Caratteristiche preferite della macchina dell’invenzione sono indicate nelle rivendicazioni dipendenti dalla rivendicazione 1. According to the invention, this purpose is achieved thanks to a machine having the characteristics referred to specifically in claim 1 below. Preferred features of the machine of the invention are indicated in the claims dependent on claim 1.
Costituisce un ulteriore oggetto della presente invenzione un procedimento di produzione di praline che utilizza la suddetta macchina, come indicato nelle rivendicazioni 9 e 10 che seguono. A further object of the present invention is a process for the production of pralines which uses the aforesaid machine, as indicated in the following claims 9 and 10.
La macchina dell’invenzione è in grado di dosare ripieno e rivestimento in stampi aventi in linea di principio un numero ed una disposizione qualsiasi di alveoli, senza necessità di effettuare alcun riallestimento di parti meccaniche, ma semplicemente programmando in modo corrispondente i movimenti dello stampo in un piano orizzontale e dell’elemento dosatore lungo un asse verticale. The machine of the invention is able to dose filling and coating in molds having in principle any number and any arrangement of cavities, without the need to carry out any rearrangement of mechanical parts, but simply by correspondingly programming the movements of the mold in a horizontal plane and of the metering element along a vertical axis.
Inoltre, anche quando si cambiano i materiali costituenti rispettivamente il ripieno e/o il rivestimento, le operazioni di pulizia sono molto brevi e generano un ridotto quantitativo di scarti. Furthermore, even when the materials constituting the filling and / or the coating respectively are changed, the cleaning operations are very short and generate a small amount of waste.
Ulteriori vantaggi e caratteristiche della presente invenzione risulteranno evidenti dalla descrizione dettagliata che segue, fornita a titolo di esempio non limitativo con riferimento ai disegni annessi, in cui: Further advantages and characteristics of the present invention will become evident from the following detailed description, provided by way of non-limiting example with reference to the attached drawings, in which:

La figura 1 illustra una macchina dosatrice per la produzione di praline 10, ognuna delle quali (figura 2) consiste di un ripieno 12 circondato da un rivestimento 14. Figure 1 illustrates a dosing machine for the production of pralines 10, each of which (Figure 2) consists of a filling 12 surrounded by a coating 14.
La macchina dosatrice è provvista (figure 3 e 4) di un telaio di sostegno comprendente una base 16 montata su rotelle e portante una porzione inferiore sostanzialmente parallelepipeda 18, dal cui retro si ergono montanti 20 dalla sommità dei quali protrude trasversalmente una porzione a mensola 22 attraversata da una colonna 24. The dosing machine is provided (Figures 3 and 4) with a support frame comprising a base 16 mounted on wheels and carrying a substantially parallelepiped lower portion 18, from the rear of which uprights 20 rise from the top of which a shelf portion 22 protrudes transversely. crossed by a column 24.
Al retro dei montanti 20 sono fissati un primo ed un secondo serbatoio 26a, 26b atti a contenere rispettivamente il materiale di ripieno e di rivestimento delle praline 10 e dai quali si dipartono rispettivi condotti di deflusso 28a, 28b. Attached to the rear of the uprights 20 are a first and a second reservoir 26a, 26b adapted to contain respectively the filling and coating material of the pralines 10 and from which respective outflow ducts 28a, 28b branch off.
Ogni serbatoio 26a, 26b comprende (figure 3-5) un corpo cilindrico con un fondo rastremantesi da cui si diparte il condotto di deflusso 28a, 28b, ed è provvisto di una tramoggia di carico 30 e di un’apertura 32 di ingresso di aria compressa. Un sensore 33 permette di monitorare entro i serbatoi 26a, 26b la pressione che spinge nel rispettivo condotto di deflusso 28a, 28b il materiale di ripieno e di rivestimento. Each tank 26a, 26b comprises (Figures 3-5) a cylindrical body with a tapering bottom from which the outflow duct 28a, 28b departs, and is provided with a loading hopper 30 and an air inlet opening 32 tablet. A sensor 33 allows to monitor within the tanks 26a, 26b the pressure which pushes the filling and lining material into the respective outflow duct 28a, 28b.
Il corpo ed il fondo di ciascun serbatoio 26a, 26b sono provvisti di mezzi di termostatazione, in particolare resistenze elettriche 34, per tenere i materiali contenutivi ad una temperatura tale da garantire la fluidità desiderata. The body and the bottom of each tank 26a, 26b are provided with thermostating means, in particular electric resistances 34, to keep the containing materials at a temperature such as to guarantee the desired fluidity.
I condotti di deflusso 28a, 28b sfociano (fig. The outflow ducts 28a, 28b open out (fig.
4) in un elemento dosatore 36 il quale, insieme con i relativi mezzi di azionamento lungo un asse verticale costituiti in particolare da un organo attuatore 38, è sopportato dalla colonna 24 del telaio di sostegno. 4) in a metering element 36 which, together with the relative actuation means along a vertical axis consisting in particular of an actuator member 38, is supported by the column 24 of the support frame.
L’elemento dosatore 36 presenta (figure 6-8) un ugello di scarico verticale 40 a struttura coassiale con un condotto centrale 42 ed un condotto circostante 44 disposto a corona intorno al condotto 42, ed una prima ed una seconda valvola 46a, 46b atte a porre selettivamente in comunicazione il condotto di deflusso 28a del materiale di ripieno con il condotto centrale 42, e rispettivamente il canale di deflusso 28b del materiale di rivestimento con il condotto circostante 44. The metering element 36 has (Figures 6-8) a vertical discharge nozzle 40 with a coaxial structure with a central duct 42 and a surrounding duct 44 arranged in a crown around the duct 42, and a first and a second valve 46a, 46b suitable for to selectively put in communication the outflow duct 28a of the stuffing material with the central duct 42, and respectively the outflow duct 28b of the lining material with the surrounding duct 44.
Le valvole 46a, 46b sono collocate l’una a fianco dell’altra entro una camera 48 provvista di mezzi di termostatazione, in particolare resistenze elettriche 50, per tenere i materiali fluenti alla temperatura desiderata. The valves 46a, 46b are placed side by side within a chamber 48 provided with thermostating means, in particular electrical resistances 50, to keep the materials flowing at the desired temperature.
Ciascuna valvola 46a, 46b presenta (fig. 9) un canale radiale 52 avente un’entrata in comunicazione con il rispettivo condotto di deflusso 28a, 28b ed un’uscita che sfocia in un canale centrale longitudinale 54 provvisto di un otturatore 56. Each valve 46a, 46b has (fig. 9) a radial channel 52 having an inlet in communication with the respective outflow duct 28a, 28b and an outlet that flows into a central longitudinal channel 54 equipped with a shutter 56.
Il canale centrale 54 della prima valvola 46a costituisce un prolungamento del condotto centrale 42, mentre il canale centrale 54 della seconda valvola 46b costituisce un prolungamento di un condotto ausiliario 58 che sfocia nel condotto circostante 44. The central channel 54 of the first valve 46a constitutes an extension of the central conduit 42, while the central channel 54 of the second valve 46b constitutes an extension of an auxiliary conduit 58 which flows into the surrounding conduit 44.
In modo di per sé noto, l’otturatore 56 di ciascuna valvola 46a, 46b è mobile verticalmente grazie all’azione di mezzi pneumatici di comando che includono un condotto di alimentazione 60 di aria compressa comunicante con una camera 62 entro la quale è montata mobile una flangia 64 solidale all’otturatore 56 e provvista di una molla di richiamo 66. In assenza di flusso di aria, la molla 66 provoca la chiusura dell’otturatore 56 e quindi l’interruzione del flusso di materiale attraverso la valvola 46a, 46b, che è invece consentito quando l’otturatore 56 è aperto. In a per se known manner, the shutter 56 of each valve 46a, 46b is vertically movable thanks to the action of pneumatic control means which include a compressed air supply duct 60 communicating with a chamber 62 within which it is mounted movably a flange 64 integral with the shutter 56 and provided with a return spring 66. In the absence of air flow, the spring 66 causes the closure of the shutter 56 and therefore the interruption of the flow of material through the valve 46a, 46b, which, on the other hand, is allowed when the shutter 56 is open.
Uno stampo 68 (figure 6-8) presentante una pluralità di alveoli 70, ciascuno dei quali ha la forma delle praline 10 che si intende produrre, è collocato su di una piastra 72 mobile lungo una prima rotaia 74 grazie ad un primo organo attuatore 76. A sua volta, la piastra 72 è collocata su di un carello 78 mobile grazie ad un secondo organo attuatore 80 lungo rotaie 82 ortogonali alla prima rotaia 74 e fissate alla superficie di sommità della porzione inferiore 18 del telaio di sostegno. Nel complesso, lo stampo 68 è quindi provvisto di mezzi che ne consentono la movimentazione in una qualunque posizione desiderata entro un piano orizzontale sottostante la porzione a mensola 22 del telaio. A mold 68 (Figures 6-8) having a plurality of blisters 70, each of which has the shape of the pralines 10 to be produced, is placed on a plate 72 movable along a first rail 74 thanks to a first actuator member 76 In turn, the plate 72 is placed on a mobile carriage 78 thanks to a second actuator member 80 along rails 82 orthogonal to the first rail 74 and fixed to the top surface of the lower portion 18 of the support frame. Overall, the mold 68 is therefore provided with means that allow it to be moved to any desired position within a horizontal plane under the bracket portion 22 of the frame.
La macchina è inoltre provvista di un pannello di controllo 84 per l’impostazione e la gestione del suo funzionamento. The machine is also equipped with a control panel 84 for setting and managing its operation.
Vantaggiosamente, le parti della macchina non destinate al contatto con i materiali di ripieno e rivestimento, quali il telaio di sostegno, possono essere realizzate di alluminio anodizzato certificato per ambienti alimentari, mentre le parti destinate a tale contatto, come i serbatoi 26a, 26b e l’elemento dosatore 36, possono essere realizzate di acciaio inossidabile AISI 304. Advantageously, the parts of the machine not intended for contact with the filling and coating materials, such as the support frame, can be made of anodized aluminum certified for food environments, while the parts intended for such contact, such as the tanks 26a, 26b and the dosing element 36, can be made of AISI 304 stainless steel.
Il funzionamento della macchina appena descritta è il seguente. The operation of the machine just described is as follows.
Dapprima, gli organi attuatori 76, 80 movimentano lo stampo 68 così da posizionare un alveolo 70 in corrispondenza dell’asse 86 di movimento verticale dell’elemento dosatore 36. First, the actuator members 76, 80 move the mold 68 so as to position a cell 70 in correspondence with the axis 86 of vertical movement of the dosing element 36.
Quindi, l’organo attuatore 38 fa abbassare l’elemento dosatore 36 così da posizionare la bocca dell’ugello 40 entro l’alveolo 70. A seguito dell’apertura pneumatica della seconda valvola 46b, si provoca il deflusso del materiale di rivestimento attraverso il condotto ausiliario 58 ed il condotto circostante 44 dell’ugello 40 verso il fondo dell’alveolo 70, che ne viene rivestito. Then, the actuator member 38 lowers the metering element 36 so as to position the mouth of the nozzle 40 within the cavity 70. Following the pneumatic opening of the second valve 46b, the outflow of the coating material is caused through the auxiliary duct 58 and the surrounding duct 44 of the nozzle 40 towards the bottom of the cell 70, which is coated with it.
Successivamente (figure 6 e 7), l’organo attuatore 38 inizia a sollevare l’elemento dosatore 36 e, a seguito dell’apertura pneumatica della prima valvola 46a, si provoca attraverso il condotto centrale 42 dell’ugello 40 il deflusso del materiale di ripieno entro il materiale di rivestimento che continua a defluire nell’alveolo 70 ricoprendone la parete laterale. Subsequently (Figures 6 and 7), the actuator member 38 begins to lift the metering element 36 and, following the pneumatic opening of the first valve 46a, the flow of the material of stuffing within the covering material which continues to flow into the cavity 70 covering its side wall.
Poi, si chiude la prima valvola 46a così da interrompere il deflusso dal condotto centrale 42 dall’ugello 40 del materiale di ripieno, mentre prosegue il deflusso del materiale di rivestimento attraverso il condotto di circostante 44 così da racchiudere completamente il materiale di ripieno già defluito nell’alveolo 70. Una volta che il materiale di ripieno è stato completamente rivestito, si chiude la seconda valvola 46b, terminando così il ciclo di produzione “one-shot” di una pralina 10 (fig. 8). Then, the first valve 46a is closed so as to interrupt the outflow of the filling material from the central duct 42 from the nozzle 40, while the outflow of the lining material continues through the surrounding duct 44 so as to completely enclose the filling material that has already flowed out. in cavity 70. Once the filling material has been completely coated, the second valve 46b closes, thus ending the “one-shot” production cycle of a praline 10 (fig. 8).
Va da sé che le operazioni sopra descritte possono essere ripetute un numero di volte pari a quello degli alveoli 70 presenti nello stampo 68, dopo che ogni alveolo 70 da riempire è stato di volta in volta portato in corrispondenza dell’asse 86 di movimento verticale dell’elemento dosatore 36. It goes without saying that the operations described above can be repeated a number of times equal to that of the cavities 70 present in the mold 68, after each cavity 70 to be filled has been brought from time to time in correspondence with the axis 86 of vertical movement of the 'dosing element 36.
Qualora si debba successivamente utilizzare uno stampo 68 avente un diverso numero e/o disposizione di alveoli 70, è sufficiente impostare tramite il pannello di controllo 84 i dati necessari per movimentare in successione ogni alveolo 70 del nuovo stampo 68 al di sotto dell’ugello 40 di scarico dell’elemento dosatore 36, senza dover sostituire alcun altro componente meccanico o mutare la configurazione della macchina. If a mold 68 having a different number and / or arrangement of blisters 70 is subsequently to be used, it is sufficient to set through the control panel 84 the data necessary to move each blister 70 of the new mold 68 underneath the nozzle 40 in succession. discharge of the metering element 36, without having to replace any other mechanical component or change the configuration of the machine.
Quest’ultima è quindi in grado di dosare ripieno e rivestimento in stampi 68 aventi in linea di principio un numero ed una disposizione qualsiasi di alveoli 70, semplicemente programmando in modo corrispondente i movimenti dello stampo 68 in un piano orizzontale e dell’elemento dosatore 36 lungo il suo asse verticale 86. The latter is therefore capable of dosing the filling and coating in molds 68 having in principle any number and any arrangement of cavities 70, simply by correspondingly programming the movements of the mold 68 in a horizontal plane and of the metering element 36. along its vertical axis 86.
Parimenti, anche la gestione del cambiamento di tipologia dei materiali trattati è decisamente semplificata. E’ infatti sufficiente pulire i serbatoi 26a, 26b, alimentarli con un olio neutro come l’olio di arachidi ed avviare un ciclo di funzionamento di pulizia. Tali operazioni sono veloci e producono pochi scarti, tipicamente in misura inferiore a 3 kg. Likewise, the management of the change in the type of treated materials is also decidedly simplified. In fact, it is sufficient to clean the tanks 26a, 26b, feed them with a neutral oil such as peanut oil and start a cleaning operating cycle. These operations are fast and produce little waste, typically less than 3 kg.
Naturalmente, fermo restando il principio dell'invenzione, i particolari di realizzazione e le forme di attuazione potranno ampiamente variare rispetto a quanto descritto a puro titolo esemplificativo, senza per questo uscire dall’ambito dell’invenzione come definito nelle rivendicazioni annesse. In particolare, gli alveoli ricavati nello stampo possono avere disposizione e forma qualsiasi, ad esempio sferica o semisferica. La macchina dell’invenzione potrebbe inoltre essere utilizzata per la produzione di prodotti dolciari comprendenti un numero di componenti superiori a due, ad esempio due ripieni differenti ed un rivestimento. In tal caso, la macchina comprenderà un serbatoio con un proprio condotto di deflusso per ciascun componente, l’elemento dosatore avrà una valvola per ciascun componente ed il suo ugello di scarico presenterà un numero corrispondente di condotti coassiali. In linea di principio, la struttura generale ed il principio di funzionamento della macchina resteranno comunque invariati, fermo restando che ciascuno dei componenti avrà il proprio percorso di flusso includente un proprio serbatoio, una propria valvola ed un proprio condotto nell’ugello di scarico, analogamente al caso sopra descritto ed illustrato relativo alla produzione di praline bicomponenti. Of course, without prejudice to the principle of the invention, the details of construction and the embodiments may vary widely with respect to what is described purely by way of example, without thereby departing from the scope of the invention as defined in the attached claims. In particular, the cavities obtained in the mold can have any arrangement and shape, for example spherical or hemispherical. The machine of the invention could also be used for the production of confectionery products comprising a number of components greater than two, for example two different fillings and a coating. In this case, the machine will include a tank with its own outflow duct for each component, the metering element will have a valve for each component and its discharge nozzle will have a corresponding number of coaxial ducts. In principle, the general structure and the operating principle of the machine will remain unchanged, it being understood that each of the components will have its own flow path including its own tank, its own valve and its own duct in the discharge nozzle, similarly to the case described and illustrated above relating to the production of two-component pralines.
