Towards optimal use of sulphuric acid in delinting cotton seed for mechanical planting

Khalid Ibrahim, Salaheldin B. Ahmed and El Naeim A. Ali

Abstract:

The experiment was conducted during the season 2004-2005 at Rahad Research Station to evaluate the use of 0.2 m3 blender size steered by Tractor power-take-off (PTO) shaft in delinting cottonseed chemically. The blender was found quick, safe and economical method of delinting cottonseed. There is a positive correlation between the acid volume and the amount of seed and between the time of mixing and seed weight. A significant high capacity and economic use were obtained when mixing weigh of 36 kg seeds using 2.5 liters of the acid at mixing time of 10 minutes. However, delintng operation did not affect the seed germination percentage. Based on the economical evaluation, a 0.2 m3 blender could be recommended for delinting 36 kg of cottonseeds with 2.5 liters of the concentrated sulphuric acid for the mixing time of 10 minutes.
