The Sturtevant Infestroyer® is a centrifugal, pin-type impact mill that eliminates insect infestation in flour, bakery mixes and other food products.  The milled product is accelerated by centrifugal force through a single set of whirling rotor pins. Impact with the pins and corrugated wall destroys larvae, eggs and insects insuring 100% kill without over-grinding the food product.
