This invention relates to a technique for drying heat-sensitive materials and may find application in various industries.

The aim of the invention is to intensify the process and increase the quality of drying.

Figure 1 shows an installation for the simultaneous drying and grinding of heat-sensitive materials, a longitudinal section; figure 2 - section aa in figure 1.

The installation contains a collection 1 of the material to be dried, a feed hopper 2, a drying chamber 3 with a mill 4, a separating chamber 5 and a dryer 6, separated by a partition 7 with varying angle of inclination, having an apron 8 on the axis 9, an exhaust pipe Yu, mill 11. and 12, the inlet 13 and the outlet 14 of the cyclone pipelines 15, the heat generator 16 with the burner 17, the closed conveyor 18 with the buckets 19, driven by drive sprockets 20. The mill 11 is installed opposite the gas path 21 after the cyclone 15. The conveyor 18 in, the working branch has P Stel 22.

The installation works as follows.

The dried material, such as bird droppings, is fed to the collection 1 of the material being dried, which includes a hopper 2, from which the conveyor 18 using buckets 19 feeds it to bed 22 in the dryer 6. Enter the mill

12, the material is thrown by its blades into the flow of coolant flowing sequentially from the drying chamber 3 and the cyclone 15. The temperature of the coolant in this zone is 150180 ° C "Buckets-19, working as scrapers, moving the dried material to the next mill 11, which throws it the flow of coolant in the gas path 21, having small particles of dried material, not caught by the cyclone 15. These particles in the form of a piece adhere to another / rather wet material, settling

on it that gives significant

effect on material control. Then the material enters the mill 4 of the drying chamber 3, where it is again thrown up towards the flow

heat carrier having already a temperature of 1000-1300 ° C, where it finally dries out and is carried away by the coolant to the cyclone 15. Moreover, the drying chamber 3 has a separation chamber 5,

in which large, insufficiently dried particles settle again onto the bed 22 of the conveyor 18 and re-mill 4 to the stream of hot coolant for final drying. In this installation, the heat carrier produced by the heat generator 16 and the material being dried, supplied from the feeder bin 2, are driven countercurrently.

The installation is characterized by an intensive heat and mass transfer process and a high quality of drying with low losses of the material being dried.
