While transferred from chamber to chamber flow is divided into two parts. Large fractions are mixed at level of gas distribution grate and small fractions - at level of bed by setting rate of transfer of large fractions less than rate of loading of starting carnallite in terms of dehydrated product. Three-chamber furnace of bed for realization of process has body with two lateral partitions dividing it into chambers, cap gas distribution grate forming above- grate and under-grate spaces, lower flow holes in partitions communicating above-grate spaces of adjacent chambers, separate fire-boxes for each chamber connected by under- grate spaces of the latter, loader mounted by end of first chamber distributing starting material over surface of bed and two unloaders installed at end of third chamber, one presenting drain baffle and the other located close to gas distribution grate having shutter to control amount of passing large fraction material, and lateral partitions dividing above-grate spaces of second and third chambers into sections with lower flow holes arranged in these partitions near gas distribution grate. Drain holes are made in partitions between chambers, lower flow holes in these partitions are fitted with gates to control amount of material passing through them. At least one lateral partition is additionally installed in above-grate space of first chamber that prevents getting of starting material on to surface of bed behind this partition and has one or several flow holes by gas distribution grate to divide above-grate space of this chamber into sections. In this case area of gas distribution grate in first section as material flows amounts to 65-95% of entire area of gas distribution grate of this chamber that amounts to 45-65% of whole area of gas distribution grate of all three chambers.
