一根多支管安装在机器的中央；连接有一个斜槽用于排放乳清（来自奶酪制作桶/凝乳机）和凝乳到排放桶中；在这个阶段，螺旋连续转动，把凝乳分散到排放桶的整个长度上。

From Poisson matrix, we can observe volume-preserving vector fields. By using Geiges-Gonzalo's existence of contact circle Theorem [3] , we show the existence of volume-preserving circle on3-manifolds which says that every3-manifold admits two linear independent vector fields preserving a same volume form.

通过Poisson矩阵可以观察出保积向量场，再利用Geiges-Gonzalo的接触圆存在性定理[3]，我们证明了保积圆的存在性：每个闭的3-流形上都存在两个处处线性无关的保积向量场并且它们的常系数线性组合仍是保积向量场。
