How do merchants peel the whole pecans out?

Raw pecans with walnuts should be soaked in cold water for 6-8 hours, then picked up and blanched in boiling water. When the water for pecans is boiled again, the pecans should be removed from the boiling water and cooled slightly.

Put the pecans into a special mold and break them with a small hammer.

Then peel the chopped pecans together.
