QCDIC Scheibenzentrifuge, computergesteuert (PC)

The Computer Controlled Disc Centrifuge, "QCDIC", designed by EDIBON, allows a complete study of the emulsion separation process by centrifugation, accurately reproducing the operating principles of industrial centrifuges. Its configuration integrates all the necessary elements to generate, feed, and separate a biphasic mixture. In this way, the unit enables practical analysis of accelerated sedimentation phenomena, the influence of angular velocity and feed flow rate, as well as the behavior of emulsions under a centrifugal field.

The process begins in the agitation tank, where two immiscible liquids, such as water and oil, are poured. A motor-driven agitator, controlled from the software, mixes the two phases uniformly and reproducibly. This actuator makes it possible to study how the agitation intensity affects emulsion stability, reducing the average droplet size and prolonging its homogeneity before the separation process.

Next, the emulsion is pumped by a computer-controlled pump to the disc centrifuge. This second actuator regulates the feed flow, allowing the analysis of the influence of flow rate and residence time on the separation efficiency.

The emulsion enters the centrifuge from the top and is internally distributed through the bottom of the distributor. Inside, the inclined channels between the discs shorten the sedimentation path and accelerate the phase separation, causing the denser particles to move outward while the lighter ones remain near the center. The separated liquids flow through independent outlet channels and are collected in separate tanks. The disc centrifuge, driven by the third actuator of the unit, allows adjustment of the rotational speed from the computer to analyze its direct effect on separation efficiency.

Throughout the process, three sensors record in real time the fundamental variables: the rotational speed of the agitator, the centrifuge speed, and the torque. This continuous monitoring allows evaluation of the relationship between operating conditions and separation efficiency, providing accurate information on the dynamic behavior of the process.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
