tailieunhanh - Design, development and testing of screw press machine for paddy straw under ground digester
The main objective of this research is to develop a machine for removing solid bio-digested slurry from the underground digester. In this research, a concrete digester having depth 10feet x 10 diameter was constructed and installed under the ground for biogas production. The storage capacity of this digester is 2000 kg .The application of this digester is biogas production and an alternative of LPG cylinder. The biomass used is chopped paddy straw, which gets converted into solid bio-digested slurry after an interval of three months. The main problem was removal of this solid bio-digested. To overcome this, a machine was developed according to dimensions of digester and tested. A screw press machine of length 11 feet and 4 inches diameter is designed and fabricated in that way, so that it can be handled by a single person. | Design, development and testing of screw press machine for paddy straw under ground digester
