This invention relates to a process for the preparation of digested organic supplements (DOrS). Composting of the raw material like agricultural waste and poultry droppings, mushroom spent waste, rock phosphate and other garbage, is as such known in the art. The composting process comprises in dropping the agricultural waste or other garbage into a pit or in the form of a heap which is being allowed to be decomposed in a natural manner. The other process is a mechanical composting wherein the raw material is passed through a mechanical device consisting of magnets and conveyor belt to separate out metallic objects from the agricultural waste or other garbage. The waste after removing the metallic objects is subjected to the step or crushing so as to get powder which is sieved and packed. There are disadvantages associated with the process as such known in the art. The main disadvantage is that the technology is of high standard and the initial investment is high for a small volume of compost production. Another disadvantage is that the skilled persons are required to operate the plant and the maintenance thereof is very costly.

In accordance with this invention semi decomposed raw material like agricultural waste and poultry droppings, mushroom spent waste, rock phosphate and other garbage are analysed and, dried to have a moisture of 10-15%. The raw material is then crushed to the size of 80-100 mesh before putting into the container/bio-reactor of the thumbi plant, selected cellulotytic bacterias are then put into the container of bio-reactor and the container is sealed. The sealed container is kept for 48 to 96 hrs. for the decomposition of the raw material fed into the bio-reactor. The steam is then passed through the bio-reactor at a pressure of 20 to 50 psi and temperature of 100 to 140°C. The steam is passed through the container/bio reactor upto 2 hrs. for the sterilization of the compost depending upon the quality of the waste. The composed waste is then taken out from the container/bio reactor and is subjected to the step of crushing and homogenization. The homogenized mixture so obtained is then fed into a peddle mixture and neutriants and/or additives are added therein. The additives are biological as well as chemical additives. The peddle mixture is then operated for a period upto 45 min. The mixture so obtained is then subjected to the step of pelletizer to form the pellets or is subjected to the step of extrusion or to the step of tablating machine to prepare the tablets of the mixture. The pellets or tablets or extrudates are subjected to the step of drying so as to keep the moisture between 10 to 15% weight by weight. Further, in accordance with this invention the plant used for the preparation of digested organic supplement has a vessel/container for containing the raw material therein. A plurality of wiper brushes are secured with a central shaft disposed into the vessel of the plant. Steam inlet are provided through out the vessel/bio-reactor for supplying steam into the vessel.
