In order to cure asymmetry of the flow field near the inlet and the exit of a conventional horizontal film evaporator, the following modifications were made. Liquid was supplied to the evaporator cylinder through a circumferential groove covered with a net. The circumference of the groove was divided into eight sections, each of which was connected to a different head tank so that liquid of almost equal head was supplied to all in spite of the different heights of the sections. The outlet was a simple circumferential groove. A net was installed on the rotor normal to the axis near the inlet. Experimental data showed that the circumferential variation of the liquid fillet was considerably reduced compared to the pattern observed in a conventional apparatus.
