Definitions

  • Gas flushing packaged products which are detrimentally affected by atmospheric oxygen trapped within sealed bags can be preserved an appreciable length of time by substantially flushing the oxygen from the atmosphere surrounding the products within the sealed bags.
  • oxidation and rancidity are at least greatly minimized, shelf life significantly increased and flavor and aroma are retained.
  • coffee, nutmeats, potato chips and candy are typical examples.
  • a further object of the invention is to provide a new and improved gas flushing system including an initial purging to prevent reentry of air to the product being packaged.
  • Still another object of the invention is to provide new and improved combination oxygen analysis ⁇ and start-up preflushing means in a flushing system.
  • a yet further object of the invention is to provide a new and improved method of and means for flushing in vertical forming, filling and sealing machines which is readily adaptable for either original equipment or for installation in existing machines.
  • the drawing is a schematic illustration of a flushing system as applied to a vertical bag forming, filling and sealing machine.
  • This invention is especially applicable to vertical forming, filling and sealing machines of the so-called Zwoyer type exemplified in U.S. Pat. No. 1,986,422 and an improved version thereof exemplified in U.S. Pat. No. 3,449,888, and to the extent necessary for a more complete understanding of details of such a machine, the disclosures of these patents are incorporated herein by reference. However, to the extent necessary to a full understanding of the adaptation of the present invention to such a bag forming, filling and sealing machine the more or less schematically illustrated details in the drawing should afford adequate disclosure herein.
  • a vertical bag forming tube 5 of such a machine including on its upper end means such as a hopper 7 into and through which product of generally discrete nature is supplied from a suitable source, generally in measured bag contents quantities in any preferred manner.
  • a suitable source sheetform packaging material 9 such as a suitable thermoplastic, gas impervious film, and guide the same into tubular form about the tube 5 with side margins joined in lap seal or fin seal seam relation.
  • Such material should be possessed of excellent impermeability characteristics and may comprise laminated films with polyvinylidene chloride (available commercially as Saran), foil, or combinations of materials such as polyethylene, polypropylene, cellophane, and the like with an important consideration being the films ability to resist flex cracking, breaking or pinholing of the barrier material so that, after flushing, oxygen will not be permitted to migrate into the package, but the inert gas atmosphere will be reliably retained.
  • the joined margins of the material 9 are engaged by vertical heat sealing means 10 which may comprise the usual swinging arm and frame arrangement.
  • the material travels downwardly as drawn by vertically reciprocal transverse sealing die, cut-off and pulldown mechanism l1 which is operative to heat seal across the formed tube of the material 9 to close the top of a previously filled bag and to close the bottom of a new bag 12 to be filled immediately under the lower terminal outlet of the tube 5.
  • a predetermined quantity of product to be packaged is dropped down the passage defined within the forming and filling tube 5 to be received in the bag which, while the product is dropping thereinto, is being pulled downwardly until it is two bag lengths below the filling tube outlet, whereupon the mechanism 11 separates and releases the same and returns to its upper limit and seals the filled bag, repeating the cycle.
  • the product is, in effect, washed" in an inert gas atmosphere while dropping down the passage within the forming and filling tube 5.
  • at least one flushing gas nozzle 13 which is desirably a small diameter tube duct such as on the order of one-quarter inch outside diameter, is located to extend downwardly in the passage within the tube 5 with the lower end of the duct adjacent to the lower end of the tube and with the upper end of the duct in communication through the wall of the tube 5 at a suitable point above the folding arm structure 8, as by means of a connection or fitting 14 with a delivery duct l5 by which inert gas such as nitrogen is conveyed to the nozzle 13.
  • the gas is discharged either from the lower end of the elongated nozzle 13 or distributed through a number of holes along the length thereof, as indicated schematically.
  • This provides an air purging, normal atmosphere excluding atmosphere within at least the intermediate portion of the passage within the tube 5 and within the successive bags 12.
  • an initial purging of the passage within the tube 5 is desirably effected upstream from the main flushing effected by means of the noule or distributor 13.
  • Introduction of the inert prepurging gas through the wall of the tube 5 is by way of a nozzle 17 which may be, or be on, a nipple or fitting attached to communicate through the wall of the tube 5 to the interior thereof, at a point above the member 13, and to which is connected an inert gas delivery duct 18.
  • Gas is supplied to the delivery ducts and 18 from a suitable source such as a gas generator or a gas tank 19 which may be mounted in a cabinet 20 conveniently mounted on a frame member 2l comprising part of the machine frame. From the tank 19 the gas passes by way of a supply duct 22 to a control valve 23 which may be integrated with machine operation so as to open when the machine is operating and to close automatically when the machine is stopped or shut down.
  • a control valve 23 may be integrated with machine operation so as to open when the machine is operating and to close automatically when the machine is stopped or shut down.
  • the valve 23 may be a solenoid operated valve assembly.
  • a preheater 24 may be suitably mounted in or in association with the supply duct 22 to bring the gas up to a temperature which will avoid freezing anywhere in the system.
  • the gas passes to respective flow controllers 25 for each of the delivery lines and each of which has a respective pressure gauge 27 associated therewith.
  • the gas passes on to respective flow meters 28 each of which has a pressure regulator 29 associated therewith. From the flow meters 28 the gas passes to the respective delivery ducts 15 and 18.
  • gas sampling means comprising a sampling duct 30 which is desirably located to extend downwardly within the tube 5, but which may if there is sufficient clearance within the bag material tube to accommodate the same be located outside and contiguously parallel with the tube 5 and which duct has its lower or suction end extending below the discharge end of the tube 5 so as to project downwardly within the upper portions of the freshly filled bags l2.
  • Means for filtering the withdrawn gas desirably comprise a prefilter 31 on and across the entry end of the sampling duct 30.
  • the sampling duct 30 is connected with a conduit 32 leading to a three-way valve 33 by which the duct 32 can be opened to atmosphere or connected to a sampling line 34 leading to a filter 35 such as a water filter and thence to a vacuum pump 37 from which the sample gas is delivered by continuation of the sampling line to an oxygen analyzer probe or sensor 38 connected to a readout oxygen analyzer meter 39 conveniently located on and in respect to the cabinet 20 for ready reading.
  • the sampling duct 30 herein also serves as a prepurge or start-up flushing nozzle since it extends down into the package which has been dormant during the shut-down.
  • a branch duct 40 connects the conduit 32 through the valve 33 with the gas supply duct 22,
  • the duct 40 upstream from the shut-off valve 23
  • suicient of the flushing gas through the valve 33 and the conduit 32 into the sampling duct 30 now serving as a preflush noule to purge the package 12 and start the flushing of the tube 5 before the machine is started.
  • the machine can be started and the flushing system operated in the normal manner.
  • the valve 33 By operating the valve 33, the duct 30 can be made to resume its sampling function before or after startup. Thereby, not only while the machine is running but also at or before start-up the amount or percent of bag content oxygen can be monitored and adjustably controlled.
