Walnut Shelling Machine

1. Feeding system
2. Shell breaking mechanism
Roller shell breaking: using roller extrusion, suitable for thin-shell walnuts (such as paper-shell walnuts).
Impact shell breaking: using high-speed rotating hammers or knife discs to break the shells, suitable for thick-shell walnuts (such as pecans).
3. Shell-kernel separation system
Wind sorting: using airflow to blow away lighter shell crumbs and retain heavier walnut kernels.
Vibrating screening: separating shells, kernels and incompletely shelled walnuts through screens.
4. Discharging system
Walnut kernel outlet: collecting complete walnut kernels.
Crushed shell/crushed kernel outlet: recovering incompletely separated materials for secondary processing.
