Abstract

The shells are broken up, smoothed out and saturated with chemical soln. to convert them into a bio-degradable mass equivalent to wood pulp. The machine consists of conveyor belt for coconuts, press with piston, perforator blade and container for collecting the milk; guillotine which cuts the coconut into halves; rotary knife which extracts the kernel for collection in container and multi-facet cutter and crusher for the husks; conveyor belt for the broken-up husks and compressor rolls for granulation, the granules being mixed with water in tank and impurities separated, and then heated under pressure with caustic soda, and calcium hydrosulphate to dissolve lignose. The pulp is bleached with chlorine and binder, whitener and colourant added and the mass deposited uniformly on metal mesh, which passes through a Fourdrinier machine to extract water. It is finished by passing on belt under heated calender rolls. (Reissue of the entry advised in week 9329 based on complete specification).
