ABSTRACT:
Apparatus for the aseptic packaging of high acid foods having a pH below 4.6 includes conveying means with carrier plate receptacles having orifices to receive preformed cups, the orifices being contoured to match the shape of the sealing flanges of the cups. The conveying means carries cups through a lock of liquid sterilant, past sprays that ensure against air pockets in the cups, through a bath of sterilant liquid in submerged, inverted position, lifts the cups from the bath and into a chamber of sterile inert gas, allowing liquid sterilant to drain therefrom, moves the cups in sequence to filling means and then to sealing means, where cover elements, pre-sterilized from the liquid of the cup bath, dried and preheated, are applied to hermetically close the cups by the action of heat and pressure. Jets of the sterile inert gas, recirculated from the chamber, are directed at the cups after liquid sterilant has drained therefrom, so as to dry the sealing flanges of the cups. The interior of the machine is supplied with an atmosphere of pressurized sterile inert gas, such as nitrogen. After passing through a microbiological and inert gas barrier, ejection means removes the cups from the cup conveying means.
