Definitions

  • the invention relates to a method of volumetrically filling moulds with a flowable mass, such as ice cream, whereby a first pressure cylinder associated with a filling valve is alternately filled with a predetermined volume of the flowable mass and emptied into the mould through the nozzle of the filling valve.
  • the invention relates furthermore to an apparatus for carrying out the method.
  • Such filling valves can comprise a pipe with a cylindrical valve body, and a diametrically through opening is provided in said valve body for each filling valve.
  • a 90° reciprocating turning of the valve body about its axis of rotation is controlled by the movement of the mould table and alternately opens and closes for the passage of ice cream to the mould machine.
  • the opened period is mechanically determined by the movement of the mould table and can cause a varying degree of filling in response to the pressure inside the piping system.
  • Another possibility is to allow the passing period to be determined by a weighing of each mould.
  • Both solutions involve unsatisfactory variations in the ice mass in question.
  • the time-controlled opening of the filling valves can involve a varying degree of compression of particulate ingredients in an ice mass, and the necessary interruption of the flow of ice can have the effect that particulate ingredients are compressed into lumps, which occasionally causes a clogging of the piping system.
  • the problems are increasing in proportion to an increasing particulate size and an increasing amount of the particles.
  • All the known volumetric filling valves operate on the basis of a cycle including a filling period and an emptying period, said two periods being clearly separated.
  • the filling is performed in the period including the steps of conveying the cup or the mould to be filled forwards to the filling position, and the emptying is performed in the period where the cup is placed below the nozzle of the filling valve.
  • the pressure cylinder In most volumetric filling valves the pressure cylinder is filled from a hopper or a vat by the ice cream being sucked in during the return stroke of the piston of the pressure cylinder, the resulting vacuum causing a sucking of the product into the volumetric pressure cylinder.
  • the solid particles contained therein When an ice cream-mixture is subjected to vacuum, the solid particles contained therein have a tendency to be separated from the fluid with the effect that the mixture is destroyed.
  • the use of a hopper or a vat requires a relatively soft ice cream because it must be capable of freely flowing into the cavity resulting from the retraction of the piston of the pressure cylinder.
  • the required use of a hopper or a vat only increases the problems caused by the vacuum effect on the ice cream.
  • the removal of the heat from the ice cream is one of the most expensive steps of the manufacturing process, and said removal is most efficiently performed in the ordinarily used continuously operating freezer.
  • the continuous freezer is one of the most important machines used by the manufacturing process of ice cream because it not only removes most of the heat, but also produces the ideal ice crystal structure.
  • the colder the ice cream is when it leaves the continuous freezer the less it costs to produce the ice products in question and the better the quality thereof is. Accordingly, it is rather disadvantageous to temporarily store the ice in a hopper or a vat in order to ensure the volumetric filling of the moulds before said ice passes through the filling valves.
  • the object of the invention is to provide a filling valve allowing a continuous flow of ice cream directly from the freezer through the piping system thereof and to the filling valves.
  • This object is according to the invention obtained by a second pressure cylinder associated with each filling valve being filled with a predetermined volume of flowable mass while the contents of the first pressure cylinder is being emptied, and by the second pressure cylinder being emptied through the same outlet while the first pressure cylinder is being filled again, the period of the emptying of each pressure cylinder being shorter than or equal to the period of the filling of each pressure cylinder.
  • a pressure cylinder is always ready to be filled with the flowable mass, such as ice cream, with the result that said ice cream can pass in an uninterrupted continuous flow to the filling valve.
  • the utilization of the continuous movement of the ice cream directly from the freezer has the effect that the pressure in the piping system can be used for retracting the pistons of the pressure cylinders in such a manner that said ice cream is not subjected to a vacuum.
  • the filling valve only subjects the flowable mass to a pressure when the measured amount is to be emptied into the mould or the cup in question, and this pressure can be set so as not to exceed the pressure which the mass is subjected to in the piping system from the freezer. As the flow of mass is never stopped in the piping system, the pressure remains substantially constant in said piping system.
  • the product present in said moulds is of a relatively homogeneous quality even though it is a question of mixtures containing relatively high percentages of large particles.
  • An apparatus for carrying out the method comprises a plurality of filling valves with their respective inlet for the feeding of the flowable mass under pressure and their respective outlet for volumetrically measured amounts of the mass in question, said outlet being associated with a pressure cylinder which is adapted through the valve body of the filling valve to alternately be connected to the inlet and the outlet.
  • This apparatus is according to the invention characterised in that each filling valve is associated with at least two pressure cylinders, which alternately are connected to the inlet and the outlet by means of the valve body of the filling valve.
  • the filling valves comprise a substantially cylindrical housing with a cylindrical valve body, which is pivotally journalled around the axis of said housing and provided with a recess associated with each filling valve so as to establish a connection either between the inlet and a pressure cylinder or between a pressure cylinder and an outlet by turning the valve body around its central axis.
  • This advantageous apparatus is characterised in that two identical pressure cylinders are connected in a symmetrical manner to the valve housing of each filling valve on each side of the inlet thereof, and that the valve body comprises recesses symmetrically shaped for each filling valve on each side of a radial central plane including the axis of rotation, said recesses being adapted by way of turning the valve body to alternately establish a connection between an inlet and the one pressure cylinder associated with said inlet simultaneously with establishing a connection between the corresponding second pressure cylinder and the associated outlet.
  • the pressure cylinders may advantageously be pneumatically driven piston-cylinder units.
  • Fig. 1 is a diagrammatic, sectional view through a filling valve according to the invention, seen in three different situations A, B and C during an operating cycle,
  • Fig. 2 is a side view of parts of a filling station for filling ice cream and comprising two filling valves,
  • Fig. 1 illustrates an apparatus according to the invention, where a sectional view is shown through a filling valve designated the general reference numeral 1.
  • This filling valve is one of a plurality of filling valves formed by a cylindrical housing 2, in which a valve body 3 is accommodated and sealingly abuts the inner side of the housing in a conventionally known manner.
  • the valve body 3 is preferably made of a rod-shaped body of plastics, such as neoprene, and is common to all the filling valves. Opposite each filling valve, the valve body 3 comprises a symmetrically shaped recess 4 and 5 on their respective side of a radial central plane including the axis of the valve body. These recesses are shaped such that alternately they can establish a free flow between an inlet 6 connected to the valve housing and one of two openings 7 and 8, respectively, into one of two pressure cylinders 9 and 10, respectively, connected thereto, and between the opening 7 and 8, respectively, of one of the pressure cylinders 9 and 10, respectively, and an outlet 1 1 associated with the housing 2.
  • each filling valve 1 is symmetrically shaped about a vertical central plane.
  • the two pressure cylinders 9 and 10 are therefore also completely identically shaped.
  • the pressure cylinders 9 and 10 are diagrammatically and only partially sectionally shown, and they comprise their respective piston 12 and 13 and a piston rod 14 and 15, respectively. They are in a manner not described in greater detail connected to a compressed air source for pressing the pistons 12 and 13 forwards towards the openings 7, 8 into the valve body 3.
  • the inlet 6 of the filling valve 1 is in a manner not described in greater detail connected to a piping system, in which ice cream is fed under pressure from a continuously operating freezer.
  • a setting of the valve body 3 in the position shown in Figure A the ice cream is fed from the inlet 6 directly into the pressure cylinder 9 accommodated to the right as indicated by the arrow 16.
  • the entering ice cream 16 has the effect that the piston of the pressure cylinder 9 is pressed backwards until a desired volume of ice cream is present in the interior of the pressure cylinder.
  • the valve body 3 is turned approximately 90°clockwise in such a manner that the flow of ice cream is now carried from the freezer and directly into the interior of the second pressure cylinder 10, cf. the arrow 17 in Figure B, while the piston 13 is being pressed backwards.
  • the piston 12 of the first pressure cylinder 9 is activated so as to force the volumetrically measured amount of ice cream out of the interior of the pressure cylinder 9 and out through the outlet 1 1 of the filling valve, cf . the arrow 18, and further downwards into a mould therebelow.
  • the emptying process is driven by compressed air and must, as mentioned, be completed when the filling of a pressure cylinder 9, 10 has been terminated.
  • the emptying process can be performed at a higher speed, but it cannot be performed at a speed slower than the speed of the filling process. Therefore an empty pressure cylinder is always ready for receiving a fresh amount of ice cream when a pressure cylinder has been filled up.
  • the turning of the valve body 3 must be performed relatively quickly in such a manner that no substantial, noticeable stopping of the flow of ice cream through the inlet occurs during the adjusting process.
  • the volume of the individual pressure cylinders is accurately adjusted in a manner known per se by means of screws 20 and 21 and 22 and 23, respectively, at the ends.
  • the pressure cylinders are besides of a conventionally known type.
  • Fig. 2 is a side view of an embodiment of an apparatus according to the invention which comprises two filling valves.
  • these filling valves are identically structured and both are similar to the one shown in Fig. 1 , the parts illustrated have been provided with the same reference numerals as in Fig. 1 and with a mark (') or double mark (") indicating whether they are associated with one filling valve 1 ' or the other 1 ".
  • the outlets 1 1 ' and 1 1 " as well as one of the associated pressure cylinders 10' and 10" of these filling valves 1 ' and 1 " appear.
  • the filling valves comprise a common housing 2 and a common valve body 3, the projecting end of which appears to the right.
  • valve body is driven by means of a compressed air cylinder 24 accommodated at the other end and comprising a downwardly projecting piston rod 25, of which only a portion appears from the drawing.
  • This piston rod engages a pin not shown which is connected to the valve body 3.
  • the filling valves with the associated pressure cylinders are mounted on a frame 26, only a portion of said frame appearing.

Abstract

Un procédé qui permet le remplissage volumétrique de moules avec une masse fluide telle que de la crème glacée, implique qu'un premier cylindre sous pression (9, 10), associé à une soupape de remplissage (1), soit alternativement rempli avec un volume déterminé de cette masse fluide puis vidé dans un moule au travers de la sortie (11) de cette soupape de remplissage (1). Un deuxième cylindre sous pression (9, 10), associé à cette soupape (1) est rempli d'un volume déterminé de masse fluide tandis que le contenu du premier cylindre sous pression (9, 10) est vidé, le deuxième cylindre sous pression (9, 10) étant vidé au travers de la même sortie (11) tandis que le premier cylindre sous pression (9, 10) est à nouveau rempli. La durée de vidange de chaque cylindre sous pression (9, 10) est inférieure ou égale à celle de leur remplissage, un cylindre sous pression (9, 10) vide étant ainsi toujours disponible pour recevoir la masse fluide quand l'autre est plein.
