NOVELTY - Soft group network-shaped aerobic fermentation device comprises heat and moisture insulation waterproof cover and soft net-shaped container. The soft net-shaped container is covered with heat and moisture insulation waterproof cover set with breathable bag. The breathable bag comprises air bags (1), breathable bag sealing clip (2) and isolation string.    USE - Soft group network-shaped aerobic fermentation device.    ADVANTAGE - The device reduces cost.    DETAILED DESCRIPTION - Soft group network-shaped aerobic fermentation device comprises heat and moisture insulation waterproof cover and soft net-shaped container. The soft net-shaped container is covered with heat and moisture insulation waterproof cover set with breathable bag. The breathable bag comprises air bags (1), breathable bag sealing clip (2) and isolation string. The air bags are made of non-woven fabric, woven cloth or woven net breathable material, knitted with high temperature resistant synthetic material. The linear material strength and thickness of air bags determines fermentation material particle size. The isolation string is string of beads connected with rope with spherical, rod shaped, prismatic or cylindrical shape. The air bag is formed between ventilation layer seam. The isolation box frame is tubular, rod, angular or U-shaped made of bamboo sticks, crop straw, plastic pipe, U-shaped timber, coated porous plastic rod or inflatable plastic sticks. The pocket of air bags is set with sealing clamp made of stainless steel or plastic covered with waterproof insulation. An INDEPENDENT CLAIM is included for aerobic fermentation of biomass agricultural waste comprising taking biomass waste, crushing, controlling water content to 30-50%, putting into soft net-shaped container, covering, fermenting for7-10 days, controlling temperature at 16 degrees C with humidity of less than 60%, drying until moisture is 15%, placing in fermentation chamber, transferring with air bags with isolation beads; and labeling air bags, sealing with sealer, and packaging with breathable bags.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of soft group network-shaped aerobic fermentation device.    Air bags (1)    Breathable bag sealing clip (2)    Isolation ball (7)
