The capacity is large, which can reach above 75% space of the drum. Only 1:1 liquid percentage would meet the technical requirement, the water consumption is small. The liquid in the drum can reach 3/4 level of drum. Therefore the fall of the skins is only 0.7 meter at maximum. The liquid moves as the pattern "8" in the drum, which can reduce skin defects such as grain cracking, loosing and so on.

装皮量大：装载率可达到75%以上，耗水极少，一般液比在1：1以上即可满足工艺要求，机械作用适中，鼓内液面可达鼓径3/4以上，因此皮张最大落差只有0.7m左右，且皮液在鼓体转动时呈∞字型作副运动，可减少裂面、松面、黑漆不掉等质量缺陷。
