ABSTRACT:
A method and apparatus for magnetic removal of nutshells from nutmeats is set forth wherein whole nuts are supplied to a glue applicator where they are covered with a water soluble glue. The covered nuts are sent to a normalizer which tumbles and conveys the nut and dissolves the binder to a substantially uniform, optimally thick coating. From the normalizer, the binder nuts are fed into a dusting drum which dusts iron filings, onto the coating and the nutshell. The coated nuts leaving the dusting drum are conveyed to a cracker which cracks the nutshells to separate the nutmeats therefrom. Cracked nutshells and nutmeats leaving the cracker is sent to a magnetic separator. To separate the coated nutshells from the nutmeat, the aggregate is conveyed past a magnetized roller, the shells being pulled from the aggregate by the roller and deposited onto a conveyor which transports the shells for collection or reprocessing. The separated shells may be sent without additional processing to be re-cracked to release more nutmeat, the aggregate being passed through a separator to remove the shells therefrom leaving behind the nutmeats.
