The product, previously washed, is discharged into the loading hopper, which with its vibrating movement conveys the chestnuts one at a time to the machine that causes the incision, where a special system of blades provides a cut of small and adjustable circular depth on the shell. Once the incision has been made, the chestnut continues on its way going to fall into the blanching machine, where through a rotating basket it stands for the desired time, and then falls onto a conveyor belt that provides for pushing the chestnut onto a sorting bench where the operator with a manual operation separates the two skins from the fruit then discharging each into its container.
