Essay On Groundnut

1] INTRODUCTION

Paper is a thin material produced by pressing together moist fibers, typically cellulose pulp derived from wood, grasses, and drying them into flexible sheets. Paper is a versatile material with many uses. While the most common is for writing and printing , it is also widely used as a packaging material, in many cleaning products, in a number of industrial and even as a food ingredient -- particularly in Asian cultures. Paper and the pulp papermaking process, was said to be developed in China during the early 2nd century AD. Groundnut is also of value as rotation crop. As it is the plant, it improves soil nutrients, due to the presence of atmospheric nitrogen fixing bacteria in its root nodules. Thus, all parts of groundnut plant are fully useful. Groundnut shell has great potential for commercial use. Groundnut shell is used as a fuel, filler in cattle feed, hard

These methods work differently based on the quality of pulp obtained after the process and also based on their efficiencies and also the heat energy that is required for pulping process. Mainly there are 2 methods.

2.3 Preparation for Pulp: Wood chipping is the act and industry of chipping wood for pulp but in our case we require crushed,clean and dried groundnut shells.Only the heartwood and sapwood are useful for making pulp. Most pulping processes require that the groundnut shells be crushed uniformly and evenly to get a good quality of pulp.

2.3.1. Chemical pulping: Chemical pulp is produced by combining small pieces of groundnut shells and chemicals in large vessels known as digesters where heat and the chemicals break down the lignin, without seriously degrading the cellulose fibres. Chemical pulp is used for materials that need to be stronger or combined with mechanical pulps to produce different characteristics. 3] MATERIALS AND
