\u00c0 PETITS PAS VERS L\u2019INNOVATION<\/h6>\n\n\n\n

Depuis la nuit de temps, les hommes se sont demand\u00e9s comment presser les olives. Si \u00e0 l\u2019origine ils les broyaient simplement \u00e0 l\u2019aide d\u2019un mortier \u2013 avec l\u2019ajout d\u2019eau chaude pour favoriser la s\u00e9paration et l\u2019\u00e9mersion de l\u2019huile \u2013 par la suite les inventions de l\u2019homme portent \u00e0 des nouvelles m\u00e9thodes pour la production de l\u2019huile d\u2019olive.<\/p>\n\n\n\n

\n\n\n\n
LE RESSORT PIVOTANT ET LE LEVIER<\/h6>\n\n\n\n

La premi\u00e8re grande innovation dans le pressurage des olives est l\u2019introduction du ressort tournant : une grosse pierre cylindrique, appel\u00e9 aujourd\u2019hui le broyeur \u00e0 meule, \u00e9quip\u00e9e d\u2019un axe de bois, actionn\u00e9 \u00e0 la main ou avec l\u2019aide d\u2019animaux. <\/p>\n\n\n\n

L\u2019application du principe du levier permet \u00e9galement d\u2019am\u00e9liorer ult\u00e9rieurement le rendu en huile. <\/p>\n\n\n\n

La p\u00e2te d\u2019olives, conserv\u00e9e dans des sachets en toile, est press\u00e9e \u00e0 l\u2019aide de grosses pierres, exactement comme un grand casse-noisette.<\/p>\n\n\n\n

LE PRESSOIR<\/h6>\n\n\n\n

Avec le temps, se profile \u00e0 l\u2019horizon une nouvelle invention\u00a0: la vis d\u2019Archim\u00e8de. Appliqu\u00e9e d\u2019abord \u00e0 l\u2019extr\u00e9mit\u00e9 du levier et par la suite sur le pressoir, elle est capable d\u2019exercer une pression impossible pour les humains.<\/p>\n\n\n\n

LA PRESSE HYDRAULIQUE<\/strong><\/h6>\n\n\n\n

En 1830, l\u2019agronome fran\u00e7ais Pietro Ravanas appliqua au pressoir le principe des vases communicants de Pascal. La presse hydraulique s\u2019affirme ainsi comme la technologie la plus efficace pour l\u2019extraction de l\u2019huile.<\/p>\n\n\n\n

CENTRIFUGATION<\/h6>\n\n\n\n

Dans les ann\u00e9es 1970, se diffuse un nouveau syst\u00e8me d\u2019extraction\u00a0: la centrifuge. Apr\u00e8s le broyage, la p\u00e2te d\u2019olive est plac\u00e9e dans une grosse centrifugeuse horizontale, ou d\u00e9canteur, qui s\u00e9pare l\u2019huile du tourteau et de l\u2019eau de v\u00e9g\u00e9tation.<\/p>\n\n\n\n
