Abstract
Machinery removal of sugarcane leaves reduces harvest costs, time, and effort. Therefore, designing and manufacturing a sugarcane peeling machine using locally available raw materials is of imminent importance. Three sets of drums were designed: the first is used for in-take and cleaning of stalks, the second is used to help scroll and clean stalks, and the third is used for further cleaning and discharge of stalks. The manufacture of the machine relied on metal and rubber, and used a diesel engine with a capacity of 24.5 hp and a speed of 2150 rpm. The idea was based on the principle of friction and pressure. Experimental tests were applied to study the efficiency of the machine and its effect on the crop during peeling, during which several parameters were applied. Tests were applied to (G.T.54/C9, also known as C9) sugarcane variety, which is the only commercially cultivated variety in Egypt. Parameters focused on stalk damage rate as well as on discharge distance. They were applied to both intact straight stalks, which were properly cultivated and served, and logging stalks, on three weaning periods: 10 days, 20 days, and 30 days; and at three velocities: 500 rpm, 600 rpm, and 700 rpm. The performance and efficiency of the machine through the parameters of speed (rpm), discharge distance (m), stalk damage rate (%), quantity of production (t/h), and consumption of fuel (l/h), with the age of weaning being set to 30 days, were measured. Parameters applied at a 700-rpm velocity, showed the best results in the case of straight stalks, on various parameters including discharge distance (1.55 m), stalk damage rate (0.5%), quantity of production (5.040 t/h), and consumption of fuel (1.55 l/h) at a 30-day weaning period. Parameters applied at a 600-rpm velocity, showed the best results in the case of logging stalks, on various parameters including discharge distance (0.35 m), stalk damage rate (25.34%), quantity of production (3.960 t/h), and consumption of fuel (1.45 l/h)) at a 30-day weaning period.
