The article deals with the main problems of obtaining experimental data on drying liquid dispersed products. The main difficulties of using a moisture meter to obtain kinetic curves of drying difficult-to-dry liquid materials are given. On the example of lignosulfonate drying curves of samples of liquid product in different conditions are obtained. Presented that the application of the proposed method of the experiment on the moisture meter does not lead to early completion of the operation of the analysis of the drying process.
