Mechanical Biodigester for Kitchen Waste

Organic composting forms the backbone & basic necessity of a poor farmer. The traditional methods are not sufficient & satisfactory for chopping the crop residues. Whereas buying the chemical fertilizer is not possible for every farmer due to its high cost. Organic waste chopping or shredding machine accelerates the process of composting by increasing the surface area of crop residues for aerobic degradation thereby reducing the time to obtain the compost from 4 Months to 3 Months. When the crop residues come through the hopper in the cutting chamber then due to the cutting blades & hammer blades it gets chopped into different sizes depending on the diameter of the sieve used thereby increasing the surface area of residue to decompose early. A portable machine serves for various problems like moving from one place to another, requires less space & is less bulky as compared to the existing bulky machines. It also helps the farmers to start small business thereby making them self-dependent. Machine can be used for various purposes like chopping, to obtain animal fodder, bed for poultry birds, etc. which makes it a multipurpose machine. Design & development of the machine done taking into consideration various literature reviews & needs of farmers. Fabrication with proper dimensions & consideration of required parameters provides for an efficient "Waste Food to Fertilizer Converter".
