Product Description

Screw press is a common type of press, which works by utilizing a screw shaft to push the material into a compression chamber, and squeezing the liquid out of the solids by increasing the pressure. Screw press is suitable for materials containing more fiber, such as vegetables, fruits and so on. Its advantages are simple structure, easy operation, low maintenance cost, the disadvantage is that it can not deal with large materials.

Hydraulic press, on the other hand, utilizes the principle of hydraulic transmission to squeeze out the liquid from the solid by increasing the pressure. Hydraulic presses are suitable for various types of materials, such as oilseeds, pulp, etc.. The advantages are large capacity and adjustable pressure, but the disadvantages are high equipment cost and high maintenance cost.

Centrifugal press, on the other hand, utilizes the centrifugal force and friction of high-speed rotation to squeeze out the liquid from the material. Centrifugal presses are suitable for materials with low water content, such as nuts and coffee beans. Its advantage is fast processing speed and high efficiency, and its disadvantage is that it has certain limitations for materials.

In conclusion, press is an important industrial equipment, and choosing the right type of press according to different application needs is the key. Meanwhile, reasonable design and operation can also improve the efficiency and service life of the press.
