AI Technical Summary
Technical Problem
Fresh macadamia nuts are tightly adhered to the shells, making them difficult to separate, resulting in poor edible and convenient fresh products.
Method used
The macadamia nuts are transported to a hot water tank at 60-70°C for 2-6 minutes, and then the kernels and shells are separated by a grader and a shell-breaking kernel.
Benefits of technology
It realizes effective wholeing of macadamia fresh fruits, improves the toughness and separation efficiency of the kernel, reaches more than 90%, and maintains the color and taste of the kernel.

Abstract
The invention discloses a method for taking whole kernels of fresh macadamia nuts. The method comprises the following steps: (1) removing green peels of the fresh macadamia nuts; (2) hot water heat shock soaking treatment; (3) grading; (4) taking kernels; according to the method for preparing the macadamia nuts, the whole kernels of fresh macadamia nuts are obtained, the kernels and shell fruits are instantaneously separated through instantaneous heat shock of hot water, the toughness of the kernels is also improved, and therefore the fragile rate is reduced, and the kernels are easily and completely taken out; through a contrast test, the rate of taking whole kernels (1 / 2 kernels) after hot water heat shock reaches 90% or above. After the whole macadamia nut fresh fruit kernel taking method is adopted, the color and the taste of kernels are not changed, fresh fruits can be immediately eaten or stored, the method is simple and easy to implement, in the kernel taking process, the shell breaking and kernel taking machine is arranged to quickly break shells and take kernels of nuts, meanwhile, various screening devices are arranged in the shell breaking and kernel taking machine, and the screening efficiency is improved. Therefore, reciprocating rotation and synchronous opposite stirring kernel taking work can be carried out at the same time.
