葡萄酒封装设备是由洗瓶机、灌装机、压塞机、热缩胶帽机、贴标机、装箱机、输送链等互相匹配组合而成的灌装生产线

葡萄酒冷处理目的使葡萄酒稳定； 冷冻是葡萄汁浓缩方式之一。 冷处理主要设备有： 换热器 绝热罐 换热器或冷冻机用于葡萄酒的冷处理，绝热罐用于冷处理后的保冷贮藏

In this lecture, we will derive expressions for the angular momentum and kinetic energy of a 3D rigid body. We shall see that this introduces the concept of the Inertia Tensor. Angular Momentum We start form the expression of the angular momentum of a system of particles about the center of mass

A pendulum is a rigid body suspended from a fixed point (hinge) which is offset with respect to the body's center of mass. If all the mass is assumed to be concentrated at a point, we obtain the idealized simple pendulum. Pendulums have played an important role in the history of dynamics. Galileo identified the pendulum as the first example of synchronous motion, which led to the first successful clock developed

压榨设备作用是将葡萄浆果或皮渣中的果汁或酒挤压出来，提高原料的利用率。 酿造白葡萄酒的压榨对象是除梗破碎或不除梗破碎的葡萄进行压榨取汁。 酿造红葡萄酒的压榨对象是经过除梗破碎的葡萄浸渍发酵后的皮渣

非均相物系的分离 连续相（分散介质）分散相（分散物质）非均相物系分离的目的：（1）回收分散物质（2）净制分散介质，如葡萄酒生产中的过滤

一、粉碎和筛分 （一）粉碎： 主要是借机械力将固体物料粉碎成微粉的操作过程。 起粉碎作用的机械力有冲击力（impact）、压缩力（compression）、研磨力（attrition或rubbing）和剪切力（cutting或shear）。粉碎过程一般是上述几种力综合作用的结果

In this lecture, we consider the motion of a 3D rigid body. We shall see that in the general three dimensional case, the angular velocity of the body can change in magnitude as well as in direction, and, as a consequence, the motion is considerably more complicated than that in two dimensions. Rotation About a Fixed Point We consider first the simplified situation in which the 3D body moves in such a way that there is always a point, O, which is fixed. It is clear that, in this case, the path of any point in the rigid body which is at a
