Reduction of power consumption for centrifugation process using separation efficiency model

Abstract

The power consumption, capacity, speed of rotation, separation precision and the centrifugation time are essential technical parameters of the centrifuge device, and hence their reliability may affect the system reliability and productivity. The modified period of velocity profile model (spinning period) which leads to decreasing the power consumption of laboratory centrifuge devices is derived. Based on the centrifugation time model, a fuzzy controller is proposed for the laboratory centrifuge device. The proposed controller design will produce high reliability by selecting various separation efficiencies, evaluating the separation efficiency period precisely, and reduction of separation power consumption. Based on the derived model, a low-cost controller modification leads to a shorter blood test time and lower power consumption while improving the separation efficiency to greater than 9%.
