Abstract
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.
