Definitions

  • This invention relates to a method for sanitizing filling machines and systems, in particular for food products, for the purpose of reducing the microbic load, and to the apparatus used for implementing this method.
  • the machines used for filling bottles and cans with food products are usually of the vacuum-operated type and are completely automated.
  • a device creates the vacuum in the container into which the product is to be drawn after flowing from the main source to the machine reservoir which is mounted above the filling section.
  • the liquid volume in the reservoir is controlled by a float or by suitable probes.
  • the containers are lifted towards the filling cocks on discs operated by cams, and are made to adhere hermetically against the rubber rings of the cocks, the air present in them being gradually expelled via a vent pipe on applying the vacuum.
  • the liquid is drained through a suitable pipe connected to the reservoir.
  • the total duration of the treatment depends on the initial concentration of microbes and contaminant substances present at a certain moment in the system, and which as they accumulate at each filling cycle multiply the undesirable presence of bacteria within the food product.
  • said duration depends on the degree of final microbe and bacteria concentration (in the sense of being evaluated after container filling) allowed by current national and international laws concerning food contamination.
  • a further drawback of traditional sanitizing methods is that during treatment, liquid losses frequently occur through the pipes of the filling section and in particular through the cock, because of seal imperfections or undesired leakages from the drain pipe connected to the reservoir. This results in considerable operating costs and high concentrations of contaminating emissions.
  • An object of the present invention is to indicate a method for sanitizing filling machines and systems, in particular for food products, which overcomes the aforesaid drawbacks.
  • a further object of the present invention is to carry out a sanitizing apparatus implementing said method.
  • a further object of the present invention is to completely automate the method so that the user can program and/or vary all the main operating parameters (commencement and interruption of the wash cycle, duration, quantity and quality of the chemical product to be used, liquid pressure within the pipes, liquid drainage rate from the system).
  • a further object of the present invention is to achieve an operating cost for said apparatus which is substantially less than in the known art, and further to achieve a lesser chemical contamination of the surrounding environment (compared with the known art) by the liquid used for the microbicide treatment.
  • the apparatus of the present invention comprises for the chemical sanitizer liquid at least one collection and drainage device, which is attached to a fixing pin at the base of the filling machine and is inserted (by the operation, at the moment the wash cycle starts, of two actuator cylinders mounted on the base and connected to a ring gear carrying said device) between each filling cock and the relative container support disc, to simulate a false bottle to be filled.
  • the collection and drainage device for the sanitizer liquid comprises a hollow cylinder, into which there flows the chemical wash product, a retention disc arranged to hermetically seal the device when it comes into contact with the cock of the filling section, and a movable piston arranged to close the cylinder (and simultaneously open the inlet valve for the sanitizer liquid) during liquid circulation, and arranged to open the cylinder during liquid drainage from the system.
  • Figures 1 and 2 relate to a rest state immediately preceding the commencement of treatment.
  • Figures 3 and 4 relate to a subsequent state in which the sanitizing treatment has commenced and the collection and drainage devices are aligned with the respective filling cocks.
  • Figure 5 shows the next state, in which the filling sections have been lowered until the filling cocks adhere hermetically to the top of the collection and drainage devices.
  • Figures 6 and 7 show the next stage in which the container support discs urge the pistons of the collection and drainage devices to close the device cylinders and open the inlet valves for the chemical sanitizer liquid.
  • Figure 8 represents the final state with the sanitizing treatment completed, in which the filling cocks have been withdrawn from the collection and drainage devices and the device pistons have opened the cylinders and closed the chemical liquid inlet valves, to allow complete drainage of the bacterial residues and contaminating substances, which leave the bottom of the collection devices.
  • the reference numeral 11 indicates overall the food product filling system, and 111 indicates one of the filling machines forming part of the system 11.
  • the reference numerals given hereinafter together with the description of operation of the apparatus implementing the method of the present invention relate to one of the filling machines 111 of the filling system 11 per reasons of simplicity and clarity of description.
  • the reference numeral 10 indicates the base of the filling machine 111
  • 20 indicates two pneumatic operating cylinders which rotate a ring gear 30 connected to a plurality of collection and drainage devices 70 for the chemical sanitizer liquid of the system 11.
  • these figures show four collection and drainage devices 70 for simplicity and by way of non-limiting example. These are however provided in the same number as the number of filling machines 111 forming part of the system 11.
  • Each device 70 comprises a pinion 40 adjacent to the ring gear 30, a pin 21 for its fixing to the base 10, a swivel arm 19 and a liquid collection and drainage means in the form of a container to simulate the bottle to be filled during the sanitizing of the system 11.
  • said means 60 will be known as the false bottle.
  • the reference numeral 17 indicates schematically the mechanism for moving the filling section 14 of the machine 111 (this movement being obtained by trapezium-threaded screws, not shown), 12 indicates the feed pipes for the food products and for the electronic connections required for controlling the level 25 reached in the annular reservoir 13, 70 indicates overall the collection and drainage device for the sanitizer liquid, and 80 indicates a pneumatic cylinder which, by means of an arm 90 (welded by microfusion) and a support 232, moves the disc 23 on which the containers to be filled rest.
  • the filling section 14 comprises an outer feed pipe 16 for the food product, an air vent pipe 15 and a filling cock 39 provided with a retention ring 28 and a gasket 29, these hermetically sealing the top of the false bottle 60.
  • a drain pipe 18 for the food product is connected to the reservoir 13.
  • the collection and drainage device 70 for the chemical liquid comprises the pinion 40 mounted on an idle pin 21 used for its fixing to the base 10 of the machine 111, while the false bottle 60 consists of two hollow concentric cylinders 32, 33 which slide one within the other by means of two springs 27 and support a disc 31.
  • a piston 34 which is fixed to the cylinder 33 by two springs 35 and is hollow to enable the sanitizer liquid to emerge.
  • Said liquid is fed into the filling section 14 via a valve 24, and is drained at the end of the sanitizing treatment from the cup-shaped chamber 26 which forms part of the cavity 37 of the cylinder 32 bounded by the lower end of the pipe 16 and the upper end of the piston 34.
  • the cylinder 33 is fixed by a weld 36 to the swivel arm 19 which connects it to the pin 21.
  • the described filling system uses an electronic control arrangement consisting of sensor devices, actuator devices and a suitable control program, so that the operating parameters can be freely chosen and varied within ranges predetermined by the user, using the keyboard of an electronic processor.
  • the apparatus which implements the sanitizing method of the present invention operates substantially as follows: the treatment initiation command is given after the normal operating cycle of the filling system 11 has been interrupted and the containers are no longer present on the discs 23.
  • the actuator cylinders 20 are provided with control microswitches providing a pneumatic rotation command which moves the cylinder 20 into its working position from its rest position. The rotation is fixed and is determined by the limit switches on the cylinders 20.
  • the mover mechanism 17 slides the filling section 14 in the direction of the arrow D of Figure 5, together with the cock 39, which is pressed hermetically against the top of the false bottle 60 via the ring 28, the gasket 29 and the springs 27.
  • the feed pipe is then lowered, via an aperture in the cock 39 and disc 31, into the cavity 37 within the cylinder 32, while the piston 34 adheres to the inner walls of the cylinder 32, supported by the springs 35.
  • the pipe 16 is inserted into the cavity 37 in such a manner that between the top of the piston 34 and the lower end of the pipe 16 there is left an empty cup-shaped space 26.
  • the next stage of the method comprises feeding the chemical sanitizer liquid through the valve 24 (positioned to the side of and above the cock 39 ), which is opened at the moment in which the piston 34 is made to slide within the cylinder 32 by means of the springs 35, in the direction of the arrow E of Figure 6, by the movement of the pneumatic cylinder 80 which, by means of the arm 90 and the support 232, urges the disc 23 into contact with the piston 34, with the result that the disc 31 of the false bottle 60 is squeezed against the cock 39.
  • said movement of the cylinder 80 is the same movement which also occurs during the container filling cycles, when they are brought into contact with the cock 39 by the disc 23.
  • the liquid inlet valve 24 On termination of the sanitizing method in question (its duration can be programmed by the user and depends on the type of food product used and the type of contamination produced), the liquid inlet valve 24 is closed, the mover mechanism 17 returns the filling section 14 to its rest position, such that the cock 39 moves in the direction of the arrow L of Figure 8 to withdraw from the disc 31 of the false bottle 60, and the cylinder 80 lowers to withdraw the support 232 and the disc 23 and release the piston 34 which, because of the fact that the springs 35 are released, is extracted from the cavity 37 of the cylinder 32. This latter movement causes the residues present in the cup 26 to be discharged to the outside along the cavity 55 of the piston 34, in the direction of the arrow M of Figure 8.
  • This total drainage of the cup 26 makes the sanitizing treatment particularly efficient, because the complete washing of the parts subject to contamination by bacteria is supplemented by a second wash, determined by the velocity of the liquid leaving the cup 26 and entraining all the residues with it, to achieve a high level of purity of the entire system 11.
  • the drainage cup 26 for the sanitizer liquid has a smaller outlet cross-section than the known art (liquid drainage currently takes place only at the level of the reservoir via the pipe 18), and hence the velocity of the outlet liquid is greater, with the result that it is easier to eliminate any incrustation formed in the pipes 15, 16 and in the reservoir 13.
  • they include: a greater effectiveness of washing and of removal of incrustation, microbes and contaminants compared with the known art for equal pressures of the chemical liquid fed into the machine pipes; a smaller loss of contaminant chemical liquid compared with the known art, during sanitizing treatment; a shorter working cycle compared with the known art, for the same food product used; operator safety against undesirable splashing or leakage of liquid during the sanitizing treatment; compliance with current national and international regulations regarding the emission of contaminants and the presence of microbes, bacteria, impurities and contaminants within food products; facility for completely automating the sanitizing process, so that the variables concerned (activation, deactivation, duration, quantity and type of liquid) can be chosen and programmed by the user via a keyboard.
