The pulper does not stop for cleaning, so there is no line stoppage or fluctuations in concentration. Since there is no accumulation of foreign substances inside the pulper, it can maximize its processing capacity. Being fully automated, it does not impose a burden on the operators. Even if the extraction plate of the pulper is made finer, its capacity can be maintained, significantly improving the extraction effect and greatly contributing to product productivity.

Suspended particles are injected tangentially onto the surface of a curved screen plate shaped like a bow. The screen plate is a slit plate composed of wires with a wedge-shaped cross-section. As the suspended particles flow down the screen plate with the injection flow, water passes through the slit section along with fine molecules and is discharged. Coarse raw materials flow down while aligning in the direction of flow, becoming concentrated and recovered as raw materials.

The raw materials introduced through the paper material inlet are pushed into the kneader by a feed screw and kneaded by rotating blades, fixed blades, and the casing. An air cylinder-type outlet opening adjustment mechanism installed at the paper material outlet allows for the adjustment of internal pressure and internal residence time.

To minimize pressure loss as much as possible, the pulp slurry inserted from the entrance descends in a spiral motion. In the main cone, a high-speed vortex is formed. This vortex causes the heavier rejects to gather on the inner wall, while the good quality fibers accumulate in the center, forming an upward vortex. The connection between the main cone and the secondary separator is a part that is prone to wear due to the swirling of the concentrated rejects, so a steel material with excellent wear resistance is used. The design also allows for easy replacement. This is the functional part that re-separates the rejects that have been concentrated and descended in the main cone. The vortex created by the pressurized water gathers the rejects and outer peripheral parts, which are then expelled through the discharge outlet along with water. Useful fibers accumulate in the center and are discharged through the outlet installed at the bottom of the center for recycling treatment.

The opening and closing mechanism of the inlet orifice (PAT.P) makes it easy to form the appropriate differential pressure. It enables economical operation with low energy loss (achieving approximately 25% energy savings compared to general cleaners... appropriate differential pressure = 0.5 Kg/cm²). The central core formed in the center of the primary cleaner is discharged from the upper center. This degassing mechanism allows for the smooth removal of air and soft materials from the pulp liquid. The secondary cleaner, which forms a forced vortex, reactivates the vortex energy consumed in the primary chamber, further enhancing the ability to separate foreign substances. The combination of the primary and secondary cleaners easily achieves the appropriate tail ratio. By fully automating the discharge, it has eliminated the need for manual labor in the removal of foreign substances.

This is a state-of-the-art separator that can process rough processing raw materials from the pulper at a high concentration (2.5% to 3.5%) and with precise selection (screen plates, slits of 0.1mm to 0.4mm), excelling in disintegration and screening.

This is a new concept screen where floating separation, centrifugal separation, and plate screening separation work synergistically. It advances dust removal technology one step further.

Aiming for the correct evolution of Pack Palper, Satomi has newly adopted a special rotor and a special basket in this new model.

The paper material is completely recovered due to strong disintegration and washing effects. The use of fine screen plates (round holes up to 1.0φ, slits up to 0.05mm) allows for the cutting off of residue circulation. The mechanism with a timer and air-driven valve enables unmanned operation. The compact design requires a small installation area. There is no vibration pollution.

One of the important features is that cleaning can be done easily. This machine has a double-door folding structure, making it easier to clean than any previous screen. The screen plate is made of a combination structure of special shaped wire (PAT.P), allowing for the production of slits as narrow as 0.07mm. Additionally, its surface shape has irregularities, making it a so-called turbulent flow type, which provides excellent performance in both concentration and volume. The impeller does not obstruct the discharge outlet of the pulp, and the large volume of the accept chamber acts as a cushion, making it difficult for pulsation to occur. The cavitation generated by the high-speed rotation of the impeller (tip speed 25-30 m/sec) demonstrates the powerful clogging prevention capability of the strong screen plate, preventing clogging even at high concentrations. The machine's flat shape and the small volume of the primary chamber with the impeller compared to the area of the screen plate mean that less energy is required for the impeller's agitation. The powerful shear force generated by the structure of the impeller and its high-speed rotation promotes the disintegration of undispersed pulp, resulting in a smaller tail volume.

In the raw material section, it is often used in series with a 3F screen, and the combination of round hole screens and slit screens is very effective for dust removal. When used as a screen for the paper-making room, it has a layout similar to that of conventional pressure screens; however, the feature of this machine is that it operates without issues even under larger pressure differentials (Δp) than traditional screens, and it can use high-precision screen plates (round holes of 1.0φ and slits up to 0.1mm), eliminating traditional screen problems such as clogging. Additionally, it has a very wide range of adaptability for concentration (0.3% to 1.5%), which is another characteristic. Its ability to remove hot melt, pitch, and gum is also outstanding. Furthermore, as a screen for high-quality paper, it has significant features such as the removal of seed knots and eye defects that cannot be achieved with other screens.

The CS type serves two functions in one unit. It is a high-efficiency device that performs both cleaner processing and screen basket processing in a single operation. By applying cleaner processing, it extends the lifecycle of the screen basket. It adopts a super compact and economically efficient cleaner, which is effective for energy saving and space reduction. The cleaner can be reconfigured to either normal type or reverse type. You can freely choose between slotted type or special round hole type for the screen basket.

The paper material sent from the pump flows in through the entrance attached to the tangential section, forming a swirling flow, where heavier stones and metals are eliminated as primary tails from the outer periphery. This also serves as a protective role for the screen plate. The paper material that surpasses the weir flows into a large-diameter annular chamber with a small gap between the screen plate and the rotor, where it is separated into high-quality paper material and rejects. The high-quality paper material passes through the screen plate and is sent to the next process from an outlet with the same diameter as the entrance. The rejects pass through the space between the screen plate and the rotor, entering the swirling chamber on the opposite side of the entrance, forming a vortex, while lighter foreign substances create a vortex in the center and are discharged. Foreign substances with a difference in specific gravity are discharged as tails from the outer periphery.
