If you have more than one specie of Macadamia tree, keep the nuts separate. Differences in oil and carbohydrate levels could cause scorching of the mixed nuts when roasting. There are gathering tools made especially for collecting Macadamia nuts, but a common metal garden rake used in its regular fashion or turned upside down does just as good of a job. Then use a metal household dustpan and a small piece of wood to scoop the nuts up and place in a suitable container to carry to your processing area. The nuts should be husked immediately which helps to, reduce the chance of insect and fungal invasion.
Some varieties have husks that defy removal of they are dried before husking.
This gives the nutmeats their characteristic bite or crunch. Use this wirecloth and staple it to a wooden frame so you have a container that will hold a substantial amount of nuts and provide adequate ventilation to assist the drying process promptly. Construct these appliances to a size that will provide you adequate drying area for the production of your trees. Do not fill the nuts in the trays more than two deep in order to provide more prompt drying. Place them in a well-ventilated location that has heat, which can accelerate the drying process.
