A system of four load cells and analogue transmitter connected to a PC with a DAQ device through different modules provides the option for automated weight loss measurement and data acquisition. The average velocity is adjusted by weighting twelve dynamic pressure measurements using three pitot tube rakes – each one consisting of four pitot tubes – and static pressure measurements at the wall of the duct system, prior to the inlet of the drying chamber. Additional measurements of the weight and the dimensions of samples were taken at selected time steps, out of the dryer. A custom-made virtual instrumentation application was developed in Labview® in order to operate and control the LTCD
