ABSTRACT RESULTS obtained from the experiments conducted under this study indicated that the present maca-damia nut processing can be improved significantly, An increase of kernel recovery by as much as half of the present recovery can be realized if the following changes can be implemented: 1 installing short duration compression cracking; 2 maintaining macadamia nuts at medium moisture for cracking; and 3 introducing brine separation. In addition to better recovery, energy cost can be ex-pected to be reduced. Most of all, the time needed to process nuts will be greatly reduced because of the elim-ination of drying inshell nuts at low moisture range. Processing time from inhusk nuts to salable kernels can be completed in two days. All drying will be done at night. Cash flow will improve. Factory space will also be re-duced due to drastic reduction of separation labor and storage space.
