Definitions

  • the invention relates to a device for producing and filling an aseptic mixture of a liquid or pasty base mass and an additional mass, optionally suspended in a liquid or pasty carrier, with solid product particles, comprising a delivery point for the base mass, heating and cooling means for making the base mass aseptic, and one Tank for holding the aseptic base mass, further comprising a delivery point for the additional mass, heating and cooling means for making the additional mass aseptic and a tank for the aseptically made additional mass, further comprising a merging for the basic mass and the additional mass, an aseptic mixing device downstream of the merging and an aseptic single-stage filler downstream of the mixing device.
  • infectious is intended to express the absence of harmful or spoilage microorganisms with regard to the particular item to be treated. In individual cases, this can mean the absence of vegetative microorganisms and spores, in other cases only the absence of vegetative microorganisms.
  • a mixing tank is provided as a mixing device, in which moving paddle or stirring elements are arranged.
  • the ratio of the tank volume to the hourly throughput is of the order of 1: 3 to 1: 5. It has proven to be very difficult to obtain an approximately uniform distribution of the solid particles in the liquid or pasty mass in the mixing tank. Such an even distribution could only be achieved by very violent movement of the paddle or stirring elements. However, this violent movement proves to be disadvantageous if the in the liquid or pasty base mass distributing solid particles are susceptible to destruction or fraying. This applies in particular to the production of food mixtures, such as sauces, which are to be mixed with meat, vegetable or fruit particles.
  • the invention has for its object to provide a mixing device and a method which allow the production of an aseptic mixture and avoid the difficulties of evenly distributing the solid particles onto the liquid or pasty base mass without causing damage or comminution of the solid particles.
  • the invention proposes that the mixing device is a dynamic mixing device.
  • a dynamic mixing device is understood to mean a mixing device in which the ratio of the intake volume to the hourly throughput is between 1:50 to 1: 1000, preferably approximately 1: 100 to 1: 500.
  • a so-called dynamic loop mixer with a screw cylinder, a screw conveyor rotating in this screw cylinder, a feed device for the mixture, a circulation line from one end of the screw to the other end has proven to be particularly suitable the screw and a withdrawal device for continuously withdrawing part of the mixture circulating in the form of a loop.
  • the device according to the invention is suitable, for example, for introducing solid particles, such as fruit, vegetable and meat particles, into basic compositions, the viscosity of which is in a range of 1 mPa./sec. up to 20,000 mPa./sec. can lie.
  • the size of the particles can be 1 mm to 20 mm of the side of the cube, and parts deviating from the cube shape can be correspondingly longer with the same volume.
  • a dynamic mixer which is aseptic, is particularly expected to be completely sealed to the outside, so that in particular no break-in of atmosphere into the interior is possible, and furthermore that it can be cleaned and sterilized in all product-contacting areas, for example by Liquid and superheated steam treatment.
  • the invention further relates to a method for producing and filling an aseptic mixture of a liquid or pasty base mass and an additional mass, optionally suspended in a liquid or pasty carrier, with solid product particles, in which the base mass and the additional mass are each made separately aseptic, then brought together, then mixed under aseptic conditions and the mixture thus obtained is finally filled.
  • the mixing be carried out in a dynamic mixing device.
  • the mixing can in particular be carried out in a dynamic mixing device of such a type that the ratio of the intake volume to the hourly throughput is between approximately 1:50 to approximately 1: 1000, preferably approximately 1: 100 to approximately 1: 500.
  • the mixing can take place, in particular, by circulating the combined inflow of base material and additional material in a loop-shaped way, with the ready-to-fill mixture being drawn off continuously at a branch point of the loop-like way.
  • the volume flow in the loop-shaped path at a point in front of the branching point is set greater than the volume flow of the ready-to-fill mixture which is continuously branched off.
  • the mixing can be carried out in such a way that the combined flows of the basic mass and the additional mass first run through a forced conveying section from an entry point of the combined streams to an exit point of the forced conveying section and then are returned from the exit point of the forced conveying section on a return path to the forced conveying section, wherein a part of the volume flow through the return path is branched off from this return path as a ready-to-fill mixture before the return path re-joins the forced conveying path.
  • 10 denotes a reservoir for a liquid or pasty base.
  • This storage container is followed by a heating station 12, in which the base is made aseptic by heating.
  • the heating station is followed by a cooling station 14, in which the base material is cooled to the filling temperature.
  • the heating and cooling stations 12 and 14 can also be integrated in the storage container 10.
  • An intermediate container 16 which is aseptic and receives the aseptically made basic mass, adjoins the cooling station.
  • FIG. 1 a storage container 18 for an additional mass which contains solid particles.
  • the solid particles can be suspended in a liquid or a pasty mass.
  • the solid particles are suspended in the smallest possible amount of liquid or paste that is sufficient for conveying.
  • the storage container 18 is in turn followed by a heating station 20 in which the solid particles are made aseptic and a cooling station 22 in which the solid particles are cooled to the filling temperature.
  • An intermediate container 24 then follows, which is aseptic and receives the additional aseptic mass.
  • the heating of the base mass and the additional mass often requires different temperature treatment, because it is relatively difficult to heat the additional mass containing solid particles in such a way that the core areas of the solid particles also experience a sufficient temperature.
  • the matrix is often so sensitive to temperature that it must not be exposed to the temperature that would be necessary to heat the solid particles in the core until they are aseptic.
  • a connection point 26 adjoins the two intermediate containers 16 and 24 and is followed by an aseptic dynamic loop mixer 28.
  • the inlet to the loop mixer is at its lower end and the outlet 30 at its upper end.
  • the drain 30 of the loop mixer is connected to an aseptic one-stage filler 32, the dispensing device 34 of which fills the mixture obtained into packaging container 36.
  • a loop mixer 28 is shown in FIG.
  • This loop mixer 28 comprises a cylinder 40 with a worm 42.
  • the worm 42 is supported by a shaft 44 and driven in rotation.
  • An inlet 46 is connected to the union point 26.
  • Return sections 48 adjoin the upper end of the cylinder 40 and are delimited by deflection plates 50 and an outer jacket 52.
  • the lower end of the return paths 48 is reinserted at 54 into the lower part of the cylinder 40.
  • the partial flows 56 are delimited on the one hand by the cylinder 40 and on the other hand by the deflection plates 50.
  • the combined flow from the intermediate containers 16 and 24 is continuously introduced into the cylinder 40 at 46.
  • the combined stream is conveyed upwards by mixing through the rotating screw 42 along the dashed and arrow-drawn sections 60.
  • the material emerges from the cylinder 40 and runs down through the return sections 48 again.
  • part of the returned material re-enters the cylinder 40, is conveyed upwards again in this cylinder, while another part is diverted from the material flow and upwards along the dashed and arrowed lines 62 to the outlet 30 arrives and is forwarded to the single-stage filler 32.
  • the loop mixer is hermetically sealed from the outside.
  • a vapor barrier 64 is provided, that is to say a chamber through which a stream of superheated steam flows, so that under no circumstances can atmosphere be conveyed into the interior of the loop mixer.
  • Connections 66 and 68 are also provided, through which cleaning liquid and sterilizing steam can be introduced and removed.
  • aseptic cleaning can also be done in other ways: e.g. Microorganisms, both vegetative microorganisms and spores, can also be excreted or rendered harmless by suitable filter or membrane processes, by microwave treatment, by static high-pressure treatment or high-energy radiation.
