ABSTRACT:
A process for increasing tree unit shelling efficiency includes a means of temporarily hardening the kernels of unshelled nuts to increase the efficiency of conventional nut hulling and/or shelling means. Quick freezing is used to sufficiently lower the temperature of the kernels of unshelled nuts to freeze the liquid matter contained in the kernels with minimal ice crystal formation. A higher percentage of nut kernels remain intact during hulling and/or shelling. The hulls and/or shells of the nuts remain substantially unaffected by quick freezing.
