Definitions

  • the present invention concerns a machine and a method for packaging products in powder inside a container made of deformable material (in order to create so-called "brick" packaging).
  • the present invention refers to the field of packaging for food products in powder, for example products intended for infusion and/or extraction like coffee or similar, or soluble products.
  • brick package is intended to refer to a container, generally made of a plastic, aluminium, or multilayer material, inside of which a food product is held and which has a generally parallelepiped shape which is kept by means of the vacuum to which it has been subjected before being closed.
  • the product that has fallen into the container is subjected to vibrations to allow for the subsequent dose to be added, and so on until the preset quantity has been reached.
  • the vacuum chamber must guarantee a closed, perfectly sealed atmosphere, which makes it particularly complex to include and operate the devices that complete the packaging by compacting the loose powder and folding, sealing and closing the container.
  • the vacuum chamber must have opportune and suitable seats for the containers and the containers must be kept in position while the loose powder is compacted and the container is closed and sealed.
  • the obtainment of the vacuum required (typically 0,7 ⁇ -0,9 bar) in the vacuum chamber occurs over an 8-10 second time span.
  • packaging machines have been arranged with two or more vacuum chambers, which causes, as a collateral effect, an incremental complexity in the machine and its operation.
  • the aim of the present invention is therefore that of providing a machine and a method for packaging suitable for the packaging of products in powder inside a container in a particularly simple and quick manner while guaranteeing that the end result is of the highest quality.
  • More particularly one aim of the present invention is to provide a machine for the packaging of products in powder inside a container that is simple and reliable.
  • a further aim of the present invention is that of providing a packaging method for products in powder inside a container in order to create a brick package, which is fast but which also guarantees that the end product is of the highest quality.

  • deformable material should be interpreted as any material that is able to be formed in the shape of a compact brick that is in close contact with a dose of product in powder after the air is extracted from its interior.
  • the composite PE / ALU / PET presents the characteristics needed to be a deformable material.
  • the machine 1 for packaging further comprises a vacuum chamber 10 designed to receive the package being processed coming from the filling unit 6 and to extract air from the package being processed 8, in such a way as to make the deformable material of the container 9 adhere to the compacted dose of product in powder 5 placed inside the package being processed 8; and sealing means 11 positioned in the vacuum chamber and configured to close and seal the package being processed 8 during a step of activating a vacuum in the vacuum chamber and to obtain closed and sealed packages.
  • the term “container” is intended to mean a container not yet closed and sealed, in which only some of the sides have been joined, folded and sealed, therefore.
  • the term “package being processed” is intended to indicate the container 9 together with the compacted dose of product in powder 5 which has been inserted into it. This definition applies from the moment of insertion of the compacted dose of product in powder 5 into the container 9, up to the complete closing, sealing and application of the vacuum to the container, which is designed to result in a brick package.

  • the compacting chamber 13 consists of a spindle with opposite openings with the presser element 17 sliding inside it.
  • the shape of the compacting chamber 13 substantially reproduces the form that the final brick package will have.
  • the presser element 17 is movable inside the compacting chamber 13 in a radial direction (in a centrifugal or centripetal direction).
  • the presser element 17 is first arranged in a position that is radially outside (not illustrated) and subsequently, during the loading of the product, it is moved in a radial centripetal direction in such a manner as to (gradually) increase the volume of the compacting chamber 13 (and incorporate a greater quantity of product).
  • the presser element 17 With a radial centrifugal motion the presser element 17 reaches a compacting position that is radially intermediate, corresponding for example to the position in which the compacted dose of product in powder 5 is received, in other words just before the first transfer station 7 (for example the position diametrically opposite the loading hopper 12, with reference to the embodiment of figure 1 ). Proceeding in a radial centrifugal motion, the presser element 17 reaches a radially external position for the expulsion of the compacted dose of product in powder 5 from the compacting chamber 13, at the first transfer station 7.

  • FIG. 4 An example of continuous and intermittent compacting steps is illustrated in the graph of figure 4 , in which the continuous line represents a compacting step with application of a gradual load, whereas the jagged line represents the sequence of sub-steps of advancement and retreat of the presser element.
  • the X-axis of figure 4 marks the sub-steps of application of the load and the Y-axis represents the corresponding values for the density of the product in powder, expressed in g/dm3.
