ABSTRACT:
A loading control system for a centrifuge used in, for example, a sugar refining operation, optimizes the introduction of product to be centrifuged. A loading system has an ultrasonic loading probe, a sound tube for delivering the sound signals to the sugar wall and returning to the ultrasonic probe, an analog controllable feed valve and a programmable logic controller which is used to control the operation. The logic program implements a control loop which analyses the signal from the probe and controls the position of the gate accordingly. Preferably, the system also implements a control loop for automatic adjustment of the flow rate and amount of sugar in the machine in order to optimize the loading process.
