Definitions
- the invention relates to a method for the durable packaging of food consisting of individual pieces, such as dumplings made from rice, potatoes or the like, and a device for carrying out the method.
- the invention has for its object to provide a method for the aforementioned purpose and a device for its implementation, which requires much less equipment with at least the same throughput and to carry out the known manufacturing method of bag formation lengthways and should be applicable under a filling pipe, and this combined with the proviso that the filling material should not experience any deformation impairment during degassing.
- the protective gas supply connection is opened, protective gas automatically flowing into the chamber due to the negative pressure prevailing in the chamber until normal pressure prevails again in the chamber.
- the lower slide is opened while maintaining the inert gas supply, whereby the filling material and the inert gas in the at the lower end of the filling tube, the bag contains practically no air due to the film web lying relatively close to the filling tube, which has already been formed into a continuous tube thereon, ie the residual oxygen content is only about 0.3 to 1%.
- the suction time for such a chamber is only approx. 0.8 sec / cycle in order to achieve a negative pressure of approx. 0.9 to 1 bar.
- the shielding gas flows in alone, it can be supplied under additional pressure, with the pressure equalization then only requiring approximately 0.15 sec / cycle.
- the number of cycles of the entire device is 35 bags / minute, that is, 140 dumplings / minute can be packed without further notice.
- the filling material is introduced into a lockable space in a cycle, this space is evacuated and filled with the protective gas until the pressure is equalized and then the filling material is introduced together with the protective gas supply, that is to say with the protective gas, from the space kept closed at the top into the tubular bag located underneath it, which is formed from a bag film which is continuously fed in a cycle.
- This method leads to a much simpler device, in which a chamber which can be closed at the top and bottom is arranged, to which the filling pipe connects at the bottom, through which the already evacuated and fumigated filling material reaches the tubular bag formed below the filling pipe.
- the device consists of a filling tube 1 of a known type with devices for film feeding and tube formation (conveying elements 2 and form shoulder 2 ') and elements 3 for longitudinal and transverse sealing of the bag film.
- This part of the device does not require any further explanation with regard to its details and function for the formation of bags 14 formed in the cycle, since it is generally known in sufficient detail and in all details with regard to the film guidance.
- It is essential for this device that at the upper end 4 of the filling tube 1 a chamber 7 with filling opening 8 and a discharge opening 9 opening into the filling tube 1 is provided with suction and protective gas supply connections 5, 6 which are to be opened and closed in time.
- the two openings 8, 9 are provided with pressure-tight closable slides 10, 10 'which can be actuated in alternation and which, as mentioned above, are actuated accordingly.
- the chamber 7 is located in a housing 7 'which is fastened with a holder 12 to the machine frame (not shown here), the simple drive mechanisms for the slides 10, 10' not shown here being arranged in the holder 12 and / or in the machine frame.
- the only indicated slide guides and the slide 10, 10 ' are of course designed so that a pressure-tight seal of the chamber 7 is guaranteed for the evacuation and gassing phase.
- several connections 5, 6 can also advantageously be arranged on the chamber 7, the protective gas supply connection 6 advantageously being brought to the chamber 7 below the suction connection 5 which is expediently arranged at the top.
- the tightly fitting film tube on the filling tube 1 ensures that there is practically no air in the newly formed bag and the filling tube 1 and that no air can get in, since the slide 10 always after filling and fumigation is closed again. It is therefore only necessary to evacuate the chamber 7 and to fill it with protective gas again after the upper slide 10 has been closed.
- tubular bag 14 hanging at the lower end of the filling tube 1 is in no way involved in the degassing process.
