METHOD AND APPARATUS FOR MANUFACTURING GRANULES FROM MANURE Russian patent published in 1998 - IPC

FIELD: organic fertilizers. SUBSTANCE: as mobile means 1 is displaced, perforated ladles 3 of elevator 2 catch liquid manure and, simultaneously filtering it, transfer it inside rotary perforated drum 11, in which further release of liquid fraction of manure is effected under compacting action of spiral edges 13 of loosely installed core 12. In this operation, edges 13 also crush lumps of manure and pointed end 14 of core facilitates withdrawal of foreign inclusions into vessel 16. Dehydrated manure mass is then transferred into below-disposed extruder 5. Extrusion is carried out to finally remove liquid fraction through perforations of casing 19 accompanied by compaction of mass, its heating, and expansion in chamber 23 with cleavage of fibers and subsequent curling of straightened fibers in the tip 26. Having passed nozzle 27, manure granules are dried by hot gases in rotary perforated drum 23, in which, caused by interaction with unevenness of it inside screw surface, granules are reduced to its desired size. EFFECT: improved quality of granules. 9 cl, 5 dwg
