A method and apparatus for aseptically filling containers with product, such as the bags (B) of bag-in-box containers, wherein the aseptic filling chamber (9 or 40) with a filling head or nozzle (5 or 43) therein is provided with fluid inlet and outlet lines (2,4,6,8,19,21,39 or 57,59,63) to create desired positive or negative atmospheric conditions within the chamber, so that a positive pressure can be maintained within the chamber when change over, at an aperture in the chamber, of a bag to be filled occurs, and so that after filling, a negative pressure (through line 15 or 63) can be generated to evacuate the chamber and hence remove any headspace gas from the top of the filled container prior to it being capped.

Aseptic filling apparatus

Method and apparatus for the continuous preservation of lumpy product in which the lumpy product is blanched, pasteurized or sterilized and then packaged hot or cooled, under aseptic conditions. In order to treat the lumpy product, e.g. chucks of fruit, in the gentlest possible manner, the heat treated product is continuously passed, without using pressure, to a drum (4) having a conveyor (2) therein through which a pasteurized liquid (10) is continuously circulated, the liquid (10) also being fed to the drum separate from the product under aseptic conditions, and having its level inside the drum maintained at a constant pre-selected value with excess liquid (10) being drawn off and re-sterilized for return to the drum (4), and the lumpy product inside the drum being continuously separated from the liquid by movement of the product through the drum by the conveyor (2), which is preferably in the form of a sieve insert with internal spiral rotatable within the drum (4) which is inclined.
