An aspiration system that uses airflow to separate light shells from the product after cracking.
The Hazelnut Shell Aspirator is a specialized machine operating with a closed-circuit aspiration system to separate hazelnut kernels, shells, and shriveled nuts after in-shell hazelnuts have been cracked. The incoming product is separated and discharged in five groups: uncracked nuts or coarse particles, dust, sound kernels, empty or shriveled nuts, and shells.
