A method for lifting out of shaft of leis bodies from freezing pockets of a shaft of leis freezing machine and apparatus for carrying out the method

摘要

Ice lollies are frozen in two-parted moulds which are inserted in rows of freezing pockets in an ice lolly freezing machine. The moulds are thawed loose from the freezing pockets in which freezing has been carried out, are lifted out of the freezing pockets, separated for releasing the frozen ice lollies, assembled and inserted again into a row of freezing pockets. Before the moulds are lifted, a moderate heating of the freezing pockets is carried out sufficient for thawing loose the moulds with respect to the pockets. Then the moulds are lifted and moved to a position outside the area of such freezing pockets of such freezing machine. At the position the moulds are heated for thawing loose the ice lollies. Then the moulds are separated and the ice lollies removed while the moulds are positioned outside the area of the freezing pockets. Now the moulds are moved back to the area of the freezing pockets and are inserted into an empty row of freezing pockets. A corresponding picking-up device moves the lifted moulds in close condition to a position outside the area of the freezing pockets and at such position a thawing up medium is supplied to the outer surfaces of the moulds. The moulds are then moved back to the area of the freezing pockets.
