Resumo(s)
O pinhão é um produto nacional de valor económico elevado, sendo, portanto, a sua exploração uma atividade de grande interesse.
No entanto, para que possa haver aproveitamento deste recurso, os frutos devem estar descasca-dos. O processo de descascar o pinhão é, atualmente, executado por máquinas de grandes dimensões e preços elevados, inviabilizando assim a entrada no mercado a pequenos produtores. É neste contexto que se insere a presente dissertação que visa a criação de um mecanismo de quebra da casca do pinhão acessível a pequenos produtores.
Para este efeito são realizados trabalhos experimentais para determinar o comportamento mecânico dos pinhões e analises estruturais dos componentes desenvolvidos para garantir o seu desempenho.
Finalmente, deste trabalho resultou a Concepção de uma máquina que qualquer produtor interessado pode utilizar para obter a sua descascadora de pinhões.
Pine nut seeds are a national resource of high economical value, making its exploration a worth-while activity. However, for this resource to be used, it first needs to be peeled of its shell. The shelling pro-cesses used nowadays are brought about by machines of enormous size and price, thus, prevent-ing smaller producers from taking advantage of their pine nuts. It’s in this context that the pre-sent dissertation fits, having as a goal the creation of a mechanism that shells pine nut seeds and is also affordable to small producers. In order to create this machine, experimental works took place to determine the mechanical properties of the pine nut seeds, as well as a structural analysis of the developed components to ensure performance. Finally, this work produced the concept of a machine that any interested producer can access to attain their own pine nut seed sheller.
