Development And Installation Of A Solar-Powered Peanut Grinding Machine

Peanuts were one of the various crops that have been present in the country since Spanish colonial era. Popular confections made from peanuts include salted peanuts peanut brittle and peanut butter sandwiches peanut candy bars and peanut butter cookies.The universally known peanut butter was invented in 1890. However its production was a demanding and a physically challenging process. To cope up with the demand the solution is through the use of a peanut grinding machine which significantly simplifies processing of nuts into paste. This is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The project entitled Development and Installation of Solar-Powered Peanut Grinding Machine aims to replace the conventional peanut grinding machine method because it consumes lot of time of making peanut butter. The machine has a maximum capacity of 5kg. Since peanuts have moisture content the design of the prototype included burr grinder which produce fine ground peanuts. The machine was also made from stainless steel to keep the ground peanuts from possible contamination. To ensure the grinding process the machine has a rotating mechanism which was driven by an AC induction motor at a speed of 1720rpm. The project used two solar panels of approximately 275 watts each for the continuity of supply increase of production less production cost and reduced air pollutants emission. For the continuity of supply increase of production and less production cost the machine was solar-powered.
