Definitions

  • the invention relates to an aseptic rotating positive-displacement batcher.
  • Rotating positive-displacement batchers are used in continuous packing plants characterised by high productivity. These machines comprise a rotating tank from which the product, which arrives through an inlet conduit, is introduced into containers by means of a series of filler heads which are solid in rotation with the tank and which are fed by positive-displacement pumps, also solid in rotation with the tank.
  • each filler head which supports are also solid in rotation with the tank, on which the containers are placed during the various filling phases;
  • the machines generally comprises an inlet star, which feeds the batcher with the empty containers and an outlet star which extracts the full containers from the batcher.
  • the said batchers are closed in a shell internally to which a sterile gas atmosphere, kept at a pressure slightly above that of the atmosphere, is maintained; the higher pressure permits of avoiding contact between the product and the external atmosphere.
  • a principal aim of the present invention is that of eliminating the above-mentioned drawbacks by providing an aseptic batcher, continuously functioning, in which the preliminary sterilising operations are extremely easy and secure and do not require the use of sterilising chemical substances in the parts of the machine crossed by the product.
  • a further aim of the present invention is that of providing a batcher internally to which there is no stagnation of the product.
  • An advantage of the present inveiton is that of not envisaging, internally to the batcher tank, fixed mechanical parts or parts in movement among themselves.
  • a further advantage of the present invention is that of permitting of correct filling of the containers.
  • the batcher object of the present invention, as it is characterised in the claims, which is closed in a shell in which an aseptic environment is maintained, and which comprises a rotating tank to which positive-displacement pumps and filler heads are solid, through which the product, taken from the tank by the positive-displacement pumps, exits from the batcher to be introduced in final containers; in the said batcher, the internal space comprising all of the zones of the batcher crossed by the product is sealed with respect to the outside atmosphere and is defined by walls aimed at withstanding a predetermined pressure.
  • the batcher comprises a column 20 which is placed in rotation with respect to a fixed base 22, by means of a gear 21 which meshes with a pinion (not illustrated).
  • a rotating tank 2 is solidly connected to the column 20 and rotates with it; the product to be batched enters the rotating tank 2 through an inlet conduit 6.
  • a plurality of positive-displacement pumps 3 and a plurality of filler heads 4 are solid to the column 20 and therefore to the rotating tank 2, each one of the said filler heads 4 being connected to a respective positive-displacement pump 3.
  • each filler head 4 a distributing valve 7 is envisaged, connected to the inside of the rotating tank 2 by means of a radially-arranged outlet conduit 8; further envisaged is a transit conduit 9, again relative to each filler head-positive displacement pump group, which transit conduit 9 connect the distributing valve 7 with the chamber of the relative positive-displacement pump 3.
  • Each filler head 4 further comprises an outlet mouth 10 whose opening and closing is activated by means of a shutter 11 which is slidingly solid with the cursor 12 of the relative distributing valve 7; whatever position the said cursor 12 is in, the outlet mouth 10 is always in communication with the relative transit conduit 9.
  • each distributing valve 7 can assume a first position, in which the shutter 11 closes the outlet mouth 10 and the outlet conduit 8 is in communication with the transit conduit 9, and a second position in which the shutter 11 opens the outlet mouth 10 and the outlet conduit 8 is not in communication with the transit conduit 9.
  • the pumping movement of the piston of the positive-displacement pumps 3 is obtained, as in machines of known type, by means of a fixed inclined annular guide 23 in which run a plurality of wheels 27, each solid in vertical sliding with the stem of a pump; as in machines of known type, the inclination of the guide 23 is variable so that the run, and thus the capacity of the positive-displacement pumps 3 can be varied.
  • a support 28 is envisaged below each filler head 4, on which support 28, in the inlet zone of the machine, an empty container 5 is inserted by means of an inlet star 30 and from which, in the outlet zone of the machine, the filled container 5 is removed by means of an outlet star 31.
  • Each support 28 can slide axially in such a way as to approach or distance itself from the relative filler head 4; such movement is completed by means of the lifting of a stem, not in the figure, to which a wheel 29 is solid which, during the rotation of the machine, rolls on a cam 25 made on a fixed frame 24.
  • the rotating tank 2 is constructed from thick sheet steel in order to withstand high internal pressures; furthermore, its bottom wall is convexed with its convexity turned inwardly to the rotating tank 2 itself.
  • the internal space comprising all the zones of the batcher crossed by the product, that is to say mouth of the inlet conduit 6, the inside of the rotating tank 2, the outlet conduits 8 and transit conduits 9, the inside of the filler heads 4 and the chambers of the positive-displacement pumps 3, is sealed with respect to the surrounding area, a fact which is particularly relevant with regard to what follows.
  • the various filler heads 4 reach a circular section A of the machine in which the positive-displacement pumps 3 effect the delivery and a circular sector B of the machine in which the positive-displacement pumps 3 effect the aspiration.
  • sector B the outlet mouths 10 of the filler heads 4 are closed by the shutter 11 and the outlet conduits 8 and transit conduits 9 are in mutual communication; in this sector the positive-displacement pumps 3 effect the aspiration run and fill up with the products coming from the tank 2.
  • the command means 26 lift the cursor 12 so as to interrupt communication between the 8 and transit conduit 9 and open the outlet mouth 10; contemporaneously the delivery phase of the relative positive-displacement pump 3 is activated, which sends the product through the outlet mouth 10 into the underlying container 5.
  • One of the advantages of the batcher of the invention is represented by the fact that the container can be lifted up until its bottom is at the level of the outlet mouth 10 of the relative filler heads 4; in these conditions the filling takes place from the bottom so as to avoid any possible gas-bubble trapping internally to the product.
  • command means 26 act on the cursor 12 of the distributing valve 7 only in the case in which there is a container 5 present; in the opposite case the shutter 11 is not lifted and the product in the delivery phase re-enters the rotating tank 2 through the outlet conduit 8 and transit conduits 9 which remain in communication.
  • the machine in question makes the initial operations of cleaning and sterilisation, which are necessary before any work cycle of the machine can begin, very simple and safe.
  • the sterilisation phase is effected in "dynamic" conditions; the machine is made to function, pretending that the steam that has been introduced into it represents the product. In these conditions all the parts of the machine which, during the filling operations, will come into contact with the product, come also, in this phase of "dynamic" sterilisation, into contact with the high-temperature steam which thus sees to a perfect sterilisation.
  • the cleaning operations are effected under dynamic conditions; the special conformation of the tank ensures, at the end of the operation, that the cleaning fluid is perfectly drained.
