fug. The invention relates to the drying of difficult-to-come thermolabile materials. Juveniles of vegetable origin, such as grain, grass seed and short stem seed heap, me, kokuskov potatoes and vegetables, etc. A characteristic feature of these materials is a quick warm-up. and extremely slow moisture removal. In addition, the maximum permissible temperature of their heating, as a rule, does not exceed 50-70 ° C. These circumstances impose known restrictions on the use of high-temperature heat-transfer agent, which clearly reduces the possibility of intensifying the drying process and increasing its efficiency. A known dryer for disinsection of grains, containing a loading auger, a drying 1bud and installed at an angle of 45 ° to the horizon, is a system of 1pc cylinders with blades around the periphery 1. The disadvantage of this dryer is the impossibility of blowing grain through the cylinder while mixing it from the cylinder to the cylinder. A known device for drying loose materials, containing a vertical cornus with separate drums in it to move the dried material, one located one above the other, and the surface of the drum is perforated and provided with paddles, and pipes for inlet and output of the heat carrier 2. This installation is with the speed limiter regulating the impossibility of the heat carrier. Mostly, it is close to the invention square. 1 a dryer for bulk materials, comprising a conveyor and mechanical tedders installed over the eio working branch in the form of 1 enlarged cylinders with blades on their outer surface and a heat transfer inlet connection pipe 3. A disadvantage of the known sump in; The unsatisfactory intensity of the sunswire progression is unsatisfactory. Ile.ib invention - intensification 11 |) process. This goal is achieved by the fact that in the dryer for sonorous materials, the content of the conveyor and mechanical tedders installed above its working branch are in the form of vrashayun cylinders with blades on their external surface and heat transfer nipple, each cylinder of tedder is made of gyula.m and the holes are perforated, and the blades are removable and installed with a slope in the direction of rotation of the spud, and the agitator in the upper part is equipped with a semi-cylindrical casing with a regulator and a hole for discharging the spent heat carrier. 10 6 FIG. 1 shows a diagram of the dryer; in fig. 2 is a wither, side view; in fig. 3 is a section. Л-А in FIG. 2. The dryer for bulk materials includes a housing 1 in which a perforated conveyor 2 is located, a heat transfer inlet pipe 3, a waste heat exchanger outlet 4, a wet material hopper 5 and a chute 6 for discharging dry material. Above the upper working branch of the conveyor 2 are mechanical tedders 7, each of which consists of a hollow perforated cylinder 8, on the outer surface of which are removable masts 9. mounted with a tilt in the direction of rotation of the agitator at an angle to the side of the natural slope of the above material. From the end, the turners are filled with solid walls 10. On the perforated surface of the cylinder 8 there is fixed one valve 11 freely opening in the lowest position. A semi-cylindrical casing 12 with an adjustable hole 13 in its upper part is installed above each Voropshtel 7 to drain the heat carrier. The device works by following its HUMAN MATERIAL; from the bunker about coming in a thick layer on the perforated mite 2. Unshake along the soup 1kil. The material enters the zone of action of the first agitator, which, with the help of junction 9, grips the material, lifts it up, transfers it over the perforated pilipdric surface 8, and then dumps it again into the layer, already in another pile from the agitator. While mixing in a dense layer, the material is subjected to unresolved by the next spinner, and so on, until it leaves the dryer but estrus 6. Randomly slip through the perforation of the fines out of the cylinder through valve 11, which ca: spontaneously opens , g; and go to the edge. M lower position. The heat carrier of the nozzle 3 enters the space bounded by the tape 2 and the clamp 1 of the shoe. Filtering at a very C} boundary velocity through a dense layer, the heat carrier in the main stream rushes through the weaker, thinner places under the springs. A passage between the deaf walls 10 through the perforations of the 1P1 cylindrical 1C) hull 8, the heat carrier is wiped. The material that is poured between the blades 9 and poured from them into the layer. Casing 12 interferes freely. I exit coolant. After working up to the required temperature and relative humidity, the heat-transfer fluid leaves the drying unit through an adjustable hole 13 and then through the nozzle 4.

To increase the productivity of the drying unit without increasing its size, it is very important that the blades 9 are set at an angle (X equal to the angle of the natural ratio of the material being dried) relative to the agitator radius.

The dryer is designed to replace blades. For example, for a short stem seed heap instead of a solid. X

Scrapers are installed whip. This makes the installation more versatile.

Each agitator is bounded by a casing with an adjustable outlet in the upper part, which allows, depending on the moisture content of the material, as the drying proceeds, the speed and, most importantly, the temperature and humidity state of the leaving heat carrier can be controlled. The latter creates favorable opportunities for

intensification of the drying process at a sufficiently high technical and economic indicators.
