FIELD OF THE INVENTION The invention relates to feed production, namely to coolers of pressed bulk materials, and especially feed pellets.

The purpose of the invention is to improve the performance properties of the cooler and improve the quality of the cooled granules.

The drawing shows schematically the cooler granules, general view, section.

The pellet cooler contains a vertical body 1 with louvers 2 on the side walls and a bladder part 3, located above the last loading window 4, pipe 5, fan 6, additional pipe 7, connecting pipe 5 with the internal space of the crumbless part 3, and the end Section 8 of the pipeline 7 is installed vertically in the no-slip part 3 of the housing 1 and is perforated to the level of the loading window 4. The pellet cooler also contains a discharge device that includes a window 9 in the bottom

: cases 1 and trays placed under it in the form of detachable boxes 10, the upper part 1 1 of each of which is rigidly connected to

casing 1, and the bottom part 12 - movable with a vibrator, made in the form

; eccentric shaft 13, one end 14

 which with the impeller 15 of the fan installed on it is located in the pipeline 5 of the fan 6, and the other end 16 is hingedly connected by an elastic plate 17 with the lower part 12 of the trays. The impeller 15 is located in the pipeline 5 between the housing 1 and the pipeline 7. The end of the additional pipeline 7 is connected to the pipeline 5 in the area between the impeller 15 and the fan 6.

During operation of the cooler, the body 1 is loaded with granules through the window 4. The granules are blown through the blinds by atmospheric air and cooled off, are unloaded. In this case, the air blown by the fan 6 through the granules in the housing 1 passes through the pipeline 5 and, acting on the impeller 15, causes the eccentric shaft to rotate, which by the end 16 through the elastic plate 17 causes the bottom 12 of the tray to vibrate, thereby unloading the granules from the housing 1.

In the operation mode of the cooler, the granule level changes within the limits of the unstained part 3 of the housing 1. When only the louver part of the housing 1 is filled with granules, the fan 6 is sucked through pipelines 5 and 7, and the impeller 15 causes the lower part 12 of the trays to vibrate at the nominal speed required for unloading granules.

With an increase in the loading rate of the cooler, the impermeable part 3 of the housing 1 is filled, the final section 8 of the pipeline 7 gradually falls asleep with granules, and when the no-locked part is fully loaded, the pipeline 7 completely closes. 7 and, accordingly, the rotational speed of the shaft 13 and the vibrations of the lower part 12 of the chutes increase, as a result of which the rate of pellet unloading increases. An increase in the rate of discharge of granules causes a drop in their level in the impermeable part 3, the openings of the louver end 8 of the pipeline 7 open, the torus of the torus 1M 6 valve begins to flow through pipeline 7, the amount of air through the pipeline 5 decreases, the speed of the shaft 13 decreases, and the discharge process decreases stabilized.

This sensitivity of the response system to a change in the level of loading of the granules on the unsightly part 3 of the housing 1 reduces its height and, consequently, reduces the mass of the cooler as a whole.

The granules, which are located in the non-blind part 3, due to the suction of air through the louvered end 8 of the pipeline 7 are pre-cooled, which reduces their crumbliness and carotene losses in the progress section in the non-closed part 3.

The amount of exhausted air through pipelines 5 and 7 to select a new operating mode can be adjusted with dampers (not shown).

The use of the proposed pelletizing cooler will reduce its material intensity by reducing the height of the jawless part of the body and improve the quality of the cooled granules.
