Light Weight Screw Press Machine for Removal of Bio-Digested Slurry

The main objective of this research is to develop the light weight screw press extraction machine which can be lifted by and operated by a person individually for extraction of bio-digested slurry from the depth of 10 feet and various viscous materials i. e. cow dung, sand etc. This machine is developed for paddy straw based biogas plant. In this plant the biogas is produced by paddy straw waste husks. The plant having capacity of 16 quintal paddy straw husks with 4 quintal cow dung. It once filled the gas produced for 3 months. After 3 months the removal of bio-digested slurry is a big problem. So the extraction by screw press is considered for removal of material. This design considered lightweight materials i. e. having single phase 1H. P motor on the top of machine.
