Pressing, separation, filtration
Pressing or in other ways separating fluids from dry matter is a central operation in many production lines and in waste water treatment.
When using presses or decanter centrifuges to separate water, fats or other fluids from dry matter, both yield and energy efficiency can be substantially improved using CORE’s adaptive control.
The quality of the outgoing fluids and the concentration achieved for the dry matter depends on how well the press, the decanter, separator or centrifuge is controlled.
CORE’s adaptive process controllers keep amperage and torque stable and variations at a minimum. Substantial savings may be achieved running the machines at a more optimal and less varying torque.
In waste water treatment, CORE’s adaptiv process controller can halve the variations in the dry matter content of the discharged cake and bring the average water content down. Dues and transport costs are typically paid per ton cake, so the saving potential can be large.
"We never reach the same high throughput manually as we do now using advanced CORE controllers. We have significantly increased capacity without loss of quality. Even more important than the increased capacity is the knowledge that we can rely on the CORE controllers what brings calmness and tranquility to the workplace."

Below, CORE’s advanced controllers for specific pressing and separation applications are listed:
FAT SREW PRESS / CORE-PRS
This controller is regulating the feed to the press (and the speed of the press if possible) in order to keep the amperage stable at the required level.
A better controlled press provides better maintenance conditions and an improved energy efficiency. A better pressing also reduces variations in the residual fat in the meal, and this also makes it possible to optimize the yields. With CORE-PRS it becomes easier to meet customer requirements and it enables operation at the desired fat level.

Fat press – With the CORE press control, feed speed (top) is increased
and motor load variations (bottom) are substantially reduced.
TWIN SCREW PRESS/ CORE-WPRS
The CORE-WPRS controller is regulating the speed of a wet press (twin screw press) and the flow to the press (if possible) in order to automatically ensure the throughput needed while keeping the press torque at the best possible level.
A better separation process in the wet press means less water in the press cake, and less energy is needed to dry the press cake. Furthermore, the variations in the residual fat/oil in the meal are reduced. A more consistent quality means that also the yields can be optimized.

Left: for a wet press, the torque variations can be substantial.
Right: CORE press control ensures a more stable and more consistent torque.
DECANTER / CORE-DEC
The CORE-DEC controller is regulating the differential speed of a decanter handling varying amounts of incoming solids. The flow through the decanter is also regulated where possible.
The controller automatically ensures the throughput needed while keeping the decanter torque at the best possible level.A better separation process in the decanter means less water in the decanter cake, and less energy is needed to dry the cake. Furthermore, the variations in the residual fat/oil in the meal are reduced. A more consistent quality means that also the yields can be optimized.

Achieve optimal separation results, the decanter must be kept at a stable and sufficiently high torque.
TRICANTER/ CORE-TDEC
The CORE-TDEC controller is regulating the differential speed of a tricanter (3-phase decanter) handling varying amounts of incoming solids. The flow through the tricanter is also regulated where possible.
The controller automatically ensures the throughput needed while keeping the tricanter torque at the best possible level. A better separation process in the tricanter means less water in the tricanter cake, and less energy is needed to dry the cake. Furthermore, the variations in the residual fat/oil in the meal are reduced. A more consistent quality means that also the yields can be optimized.
