^早是由罗马人发明的螺旋压力机，主要用于葡萄酒和橄榄油生产。约翰内斯古腾堡用一个在他的印刷机，在15世纪中叶。他的新闻基本上是一个修改后的金属版机，用于压榨葡萄和橄榄木。因此，在印刷及出版业股份的起源与工业螺旋压力机的“新闻”，因为两台机器按用螺丝机制。

在一般情况下，螺旋压榨机技术使用的粗螺纹的手柄或驱动轮的旋转转换成一个更大的力的运动。 Heyl & Patterson的多级螺旋压力机，设计的Renneburg处，一个完整长度的螺丝，航班减少间距排列在视锥细胞的直径增加。由于产品移动通过报刊，锥直径的间距和增加减少被加工的材料上施加更大的压力。

多级螺旋压力机，增加其灵活性一系列的功能，古腾堡的罗马人做梦也没想到的。 A高效的交流感应电动机，直接耦合到的转矩乘以变速箱，驱动螺杆。它的电驱动系统可以在任何速度下没有产生足够的扭矩的机械变速。一个固态逆变器转换到变频控制电动机的转速固定周期的3相供电，内置电子过载保护功能可防止传动系统损伤。此系统能够适应不断变化的进给条件下，大大降低了安装，维护和运行成本。

螺旋压力机的身体构造有支持的屏幕，周围的螺丝装配，从进料端直径不变，履行板条酒吧。

在操作时，要被处理的材料被引入在螺杆的进料端的进料斗上。连续转动将物料沿螺杆航班变得越来越密切和视锥细胞的直径增加。每个阶段施加更高的压力，并强制出更多的液体，作为一个结果。任何提取液通过一个360度的放电周围穿孔屏幕。

Heyl & Patterson的螺旋压力机是长度从4到16英尺，其直接驱动电源可设在平行或行配置。如果安装一个新的或改造的目的是作为记者，这些组合提供更广泛的选择自由。

Heyl & Patterson螺旋压力机可用于极宽的各种应用程序中，超出液体 - 固体的分离或脱水，可适于特定的和严格的各行业的需求。带式压滤机，离心机和压滤机可以使用在相同的应用，以及在更传统的应用程序，可以使用螺旋压力机。这些机器所使用的纸浆和造纸工业脱水，化工及矿产，机械压榨和混合为提取和扩散过程和独立的油和粕的鱼行业，食品行业。螺旋压力机，也可用于烟草，花了粮食，甚至回到原来的罗马根酒厂。

The screw press was first invented by the Romans, and was primarily used for wine and olive oil production. Johannes Gutenberg later used one in his printing press in the mid-15th Century. His press was basically a modified metal version of the wooden machines used for squeezing grapes and olives. Therefore, the "press" in the printing and publishing industry shares its origin with industrial screw presses because both machines press with a screw mechanism.

In general, screw press technology uses a coarse screw to convert the rotation of a handle or drive wheel into a movement of greater force. In Heyl & Patterson's Multi-Stage Screw Press, engineered by the Renneburg Division, a full-length screw with flights of decreasing pitch are arrayed on cones of increasing diameter. As product moves through the press, the decrease in pitch and increase in cone diameter exert greater pressure on the material being processed.

The Multi-Stage Screw Press adds to its flexibility with a range of features that Gutenberg or the Romans never dreamed of. A highly efficient AC induction motor, directly coupled to a torque-multiplying gearbox, drives the screw. Its electrical drive system can produce ample torque at any speed without a mechanical speed changer. A solid-state inverter transforms the fixed-cycle 3-phase power to a variable frequency that controls the RPM of the electric motor, and built-in electronic overload protection prevents drive train damage. This system is capable of adapting to changing feed conditions and substantially reduces installation, maintenance and operating costs.

The body of the Screw Press is constructed of slat-bars that hold and support a perforated screen, which surrounds the screw assembly and is a constant diameter from feed end to discharge.

When in operation, material to be processed is introduced at the intake hopper on the feed end of the screw. Continuous rotation moves the material along as screw flights become progressively closer and the cones increase in diameter. Each stage exerts higher pressures, and forces out more liquid as a result. Any extracted liquid passes through the surrounding perforated screens for a 360-degree discharge.

Heyl & Patterson's Screw Press is available in lengths from 4 to 16 feet, and its direct-drive power source can be located in either parallel or in-line configurations. These combinations offer wider freedom of choice if the press is intended as a new or retrofit installation.

The Heyl & Patterson Screw Press can be used in an extremely wide variety of applications, beyond liquid-solid separation or dewatering, and can be adapted to the specific and exacting needs of various industries. Screw Presses can be used in the same applications where belt presses, centrifuges, and filter presses may be used, as well as in more traditional applications. These machines are used by the pulp & paper industry for dewatering, chemicals and minerals for mechanical pressing and compounding, the food industry for both extraction and diffusion and the fish industry to process and separate oil and meal. The Screw Press can also be used for tobacco, spent grain or even taken back to its original Roman roots at wineries.
