System for producing organic fertilizer and a feed from excreta of domestic animal

A system for producing organic fertilizer from excreta of domestic animal as a food by using insect larvae belonging to Diptera such as Musca domestica (housefly), Boettcherisca peregrine and Tabanus, and for producing grown larvae which can be used as a feed for cultured fish and chicken raising, comprising:

• a first nurturing-processing storage unit for raising larvae hatched from eggs, said first nurturing-processing storage unit being supplied at a predetermined time interval with a predetermined quantity of the food and a predetermined number of eggs,
• a second nurturing-processing storage unit having a larger volume than said first nurturing-processing storage unit, larvae hatched from said eggs as well as said food being displaced or transferred from said first nurturing-processing storage unit to said second nurturing-processing storage unit, at a time when said larvae hatched from said eggs reach predetermined weights, wherein said second nurturing-processing storage unit is supplied with a fresh food to fatten up said larvae,
• a third nurturing-processing storage unit into which only larvae are forcibly dislodged from said second nurturing-processing storage unit at a time when the food is consumed, wherein said third nurturing-processing storage unit is supplied with a fresh food to fatten further up said larvae,
• wherein a digested residue of said food in said second nurturing-processing storage unit is recovered as a fertilizer, and said larvae are forcibly displaced from said third nurturing-processing storage unit into a recovery section at a time when the food is consumed, a digested residue of said food in said third nurturing-processing storage unit is recovered as a fertilizer, and said larvae in said recovery section are collected as a feed for other animal.

• the above processing being repeated in further nurturing-processing storage unit having a larger volume than former nurturing-processing storage unit until the final nurturing-processing storage unit which is supplied with a largest amount of a fresh food to fatten up said larvae,
• wherein only larvae are forcibly dislodged from said final nurturing-processing storage unit to a recovery section at a time when the food is consumed, a digested residue of said food in said final nurturing-processing storage unit being recovered as a fertilizer, while said larvae in said recovery section are collected as a feed for other animal.
