Abstract
Improved methods and apparatus for dry hulling or dry peeling harvested crops, particularly pistachio nuts, are disclosed. The methods and apparatus of the present invention provide crop harvesting with great efficiency resulting in consistently high percentages of hulled or peeled crops and low percentages of nut breakage, without increasing processing times regardless of the sizes of the crops being hulled or peeled. The methods and apparatus of the present invention also provide for a relatively small overall machine footprint, plus easy and efficient removal and replacement of the impingement drum to accommodate for different drum speeds, different crop sizes, different bolt patterns, different bolt sizes, and other variations allowing embodiments of the invention to be used on a wide range of nuts and vegetables of different varieties, sizes and shapes.
