dear Mr. Roberto,
The pumpkin seed dehuller is $15000 FOB China port. It can be used to dehull different kinds of pumpkin/melon seeds, of course, the result is different according to the type of seeds.
WE have exported to Mexico already, so i think it is no problem for the processing of Mexican seeds.
