FIELD: agriculture. SUBSTANCE: compost-maker has a container with side walls 3, top wall 2, bottom 6, and dumping gates 7. Ventilation ducts 5 formed by perforated walls permeable to maggots are evenly arranged across the entire height of animal waste 13 for good supply of oxygen to the whole bulk of waste so that the waste loading height is not limited by the depth of penetration of maggots. Gates 7 are opened waste loading and humus unloading while ventilation inlet 11 is moved aside. Small amounts of fly eggs (15 eggs) are placed in ventilation ducts 5, and the maggots at the third stage of development are isolated from biohumus by any method. EFFECT: higher single-load capacity. 7 dwg |
