SIG SafeBloc 12 Retort

Our SIG Retort Food filling line is your ideal choice for filling a wide range of chunky food products in sustainable carton packs.
  • Perfect choice for stews, vegetables, pulses and convenience foods, and all food products that cannot pass through a pumping system and an aseptic process.
  • 5 volumes on one machine
  • Heat-resistent carton structure: sterilization of product and package at the same time

Key features

SIG Retort Food filling machines ultrasonically seal the carton packs above the filling level, ensuring that fibers and pieces of food cannot get caught in the seal area and potentially compromise the product quality. After filling, the carton packs are transported to autoclaves, where packages and product are sterilized together.

Three-stage filling process

We developed an innovative three-stage process that starts by filling the SIG SafeBloc carton pack with products that can be pumped, then the weighed pieces are added. In the third stage, the package is topped up with a liquid. This method makes your production process very cost-effective because you can add individual product ingredients to the recipe continuously and in exactly the right quantities. This precision also gives you better control over product costs.
