  • Patent number: 4581874
    Abstract: A fitmentless, aseptic, temporarily sealed pouch is formed from two multiple-ply side walls sealed together at marginal edges. A portion of the seal is removable. Half seals joining the plies within each side wall are disposed in the side walls proximate the removable seal, but do not seal the side walls together. Apparatus and processes for handling, filling and sealing the pouch in an aseptic chamber include apparatus for moving the pouch through a sterilant bath, into and out of an aseptic chamber, a cutter for cutting off the removable seal, and vacuum jaws for engaging, stretching and opening the pouch. Once opened, the pouch is filled, then closed, sealed and moved out of the chamber through the bath.

  • Patent number: 4437315
    Abstract: A dual cooling tunnel arrangement for cooling viscous heated fluid foodstuffs in flexible bags. The flexible bags containing the heated fluids are received on pivoted wire carriers which are driven by an endless chain through an upper cooling tunnel in a first direction and returned through a second cooling tunnel in the opposite direction. In each cooling tunnel, a cooling water spray is directed on the bags in the carriers as the carriers are slowly rocked, causing the fluid in each bag to flow to different areas of the bag, altering its shape, to produce enhanced heat transfer rates and a more uniform temperature distribution throughout the fluid during cooling.
