METHOD AND APPARATUS FOR REPROCESSING OF MANURE BY SYNANTHROPIC FLY LARVAE Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, reprocessing of manure for producing of fertilizer in animal forming.

SUBSTANCE: method involves settling synanthropic flies in manure and providing conditions for laying eggs by flies and full development cycle, followed by withdrawal of larvae from reprocessed manure. Reprocessing of manure is performed in complex containing pig houses and poultry houses, chain-and-scraper conveyor for delivery and dispensing of hen dung for feeding of pigs. Manure is transported from pig houses through enclosure yards and quarantine zone via underground channels with grid-type and bridge-type ceilings. Conditions are provided for laying and providing of full development cycle of synanthropic flies under bridge ceilings on manure surface. Mature fly larvae are withdrawn from manure through openings of grid-type ceilings by hens. Apparatus has manure reprocessing vessel, devices for charging of basic manure and discharge of reprocessed manure, poultry houses with perches and pig houses with enclosure yards and feeders, which are connected with poultry houses through chain-and-scraper conveyor for removal of bird dung from under perches in poultry houses and transportation thereof for feeding of pigs. Enclosure yards for poultry are equipped with underground channels of manure removal system, said channels being arranged at different levels and providing removal of manure by gravity. Said system is provided with sluices, grid-type and bridge-type ceilings, and is further provided with hydrogen pipelines and hose for hydraulic washing away of manure. Bridge-type ceilings are arranged in equally spaced relation. Underground channels of manure removal system are communicating through underground channels of quarantine zone with underground passages positioned in enclosure yards for hens, said underground passages being equipped with bridge-type ceilings for laying of eggs by flies under said ceilings and with grid-type ceilings for withdrawal of fly larvae by hens through openings in said grid-type ceilings.

EFFECT: reduced expenses for manure reprocessing, delivery and dispensing of bird dung for feeding of animals.
