Abstract
For molding and packaging a product having paste, semiliquid or liquid form, e.g., frankfurter-type sausage paste, two films such as thermoplastic films are fed longitudinally, respectively above and below tubes feeding the product. For each of the feeding tubes, a longitudinal tubular cavity is formed between the films, e.g., by localized longitudinal welding, and the tubular cavities are filled with the product being fed. In feeding the films and the product, transverse seals are formed at intervals to terminate the filled cavities, e.g., by localized transverse welding of the films.
Claims17
A process for the continuous molding and packaging of a product in paste, semiliquid or liquid form, which comprises the following steps:
- continuously feeding a pair of films, one above and the other below the tubes feeding the product to be packaged;
- continuously shaping, between said films, tubular longitudinal cavities around each of said feeding tubes;
- fully completely, by the necessary pressure and in continuous form, said tubular cavities with the product to be packaged;
- pressing on transversal stripes over said cavities until said films come into contact and become welded, without interrupting the forward movement of the tubular cavities filled with the product, thus forming a vacuum tight package of the product therein packaged.
Process for the molding and of foodstuff substances for use in the packaging of products such as skinless frankfurter type sausage and the like, comprising providing two thermoplastic, overlapping films for shaping fixed casings for packaging and molding the product;
- feeding the films and the product to be packaged between them by a jointly sliding and continuous advancing movement;
- transversally folding one of said films to form longitudinal cavities and stripes;
- joining the longitudinal stripes of the first film by continuous welding with overlapping zones of the second film, by two correlative heating and cooling stages, respectively, while the joint continuous advance movement remains;
- introducing the product to be packaged throughout the length of the resulting tubular cavities and contains the same in longitudinal guides;
- dividing the film set and the load thereof by uniformly pressing on virtual transversal stripes which, at predetermined distances, cross said tubular cavities with their load, thus forcing the product contained therein to move;
- and, welding the films at the film joint of the longitudinal stripes, once films have come into contact in each transversal stripe.
Machine for the molding and packaging of foodstuff comprising:
- a continuous advance feeder of two thermoplastic films having guides leading to a zone where both overlapping films concur;
- a transversal folding means for one of said films, thus defining continuous longitudinal cavities alternated by longitudinal stripes overlapping the other film;
- a longitudinal unit for welding the overlapping longitudinal stripes, at the end of which outlets of a package product feeder are arranged, which loads said product throughout the length of the cavities formed by the folding means;
- and a unit for welding the transversally overlapping stripes which, with pressing means, works at predetermined distances up to the contact limit of both films in said stripes of the set of films;
- wherein each welding unit comprises heating means followed by cooling means correlatively arranged in said order according to the advance direction of the set of films.
