19、其中葡萄籽能通過說明也部分的葡萄皮經(jīng)過那里通過。具體來說，本發(fā)明是用一種在金屬板上通過一個刀片，種子和果汁是通過金屬板通過，而葡萄皮和葡萄果肉是保留在板前被收集的方法。其中， “果汁”是指從葡萄漿果果汁，或是從任意組合葡萄漿果得到的水和果汁的混合物。</p><p>　　該方法分離葡萄籽、皮分離率較高，避免了破壞種子，可稀釋葡萄汁中不好的丹寧酸。該方法的發(fā)明與儀器采用獨特的金屬板把葡萄種子與其他固體分開，如皮與種

20、子。這種發(fā)明有效的把葡萄種子與皮分開因為孔的尺寸要比葡萄皮大。</p><p>　　更具體地說，本發(fā)明提供了這樣的一個分離的步驟，包括分離葡萄皮葡萄籽的方法：進(jìn)入的葡萄通過第一和第二面和金屬板，第一面的尺寸選擇這樣的形狀：能夠使葡萄籽，果汁和皮挑選到的板塊的第二面。 （其中，除非另有說明，“葡萄”包括完整，粉碎了葡萄及其粉碎的的混合物。）葡萄從盤子上通過葉片， 在葉片和盤子之間的間隙盡可能小于葡萄種子的直徑使葡萄

21、種子不會從葉片空隙繞過。葉片的運動使盤子的表面水平并且讓盤子的表面布滿葡萄，因此葡萄種子和果汁將通過這個盤子的孔，并在這個盤子的一邊上保留葡萄皮時。這些方法適用于用葡萄生產(chǎn)葡萄酒的過程，也可以用于葡萄皮渣(也叫" 果渣" )的分離和用丹寧酸和其他有價值的化合物的抽出的葡萄種子的分離</p><p>　　雖然孔的大小，理論上有葡萄皮通過，該孔的大小和方向應(yīng)該是這樣的：葡萄皮通常是越過孔，不通過孔
