The Dali Steriflow system moves baskets of plastic milk jugs back and forth horizontally at a low frequency through the internal handling chain. The bottles must have a head space as the milk is agitated by a bubble moving inside the bottle. This agitation is enough to avoid a skin formation and browning during sterilisation. Steriflow have also designed baskets specifically for this retort to allow an easy operation system. The process used for this pasteurisation is ideal for sterilising milk bottles but can also be used for sterilising sauces in a pocket and drinks in a can.
