| Abstract | ||||
| Defoliating sugar beets without removing the crown can increase storage quality. Because the crown has lower sucrose and more impurities than the body of the sugar beet, removing the crown with knives (scalping) can result in higher sucrose per delivered ton for the producer, that increase the benefit of cultivating area. The main objectives of this study were to evaluate the performance using scalper attached of sugar beet defoliator for cleaning and scalping of the beet heads by rotating blade discs are routed across the head near the ground. Based on the forward movement during driving, the head are cut off cleanly. It is hydraulically driven. Measuring indicators were tested for the defoliator (Grimme BM300) at the tested forward speed (m/s), type of scalper (connected of scalper and pot, separately scalper) and scalper knife) and type of caliper (rubber track, steel track and steel hollow). It was found that using the tested scalper with steel hollow caliper and separately disk razor hydraulically driven under forward speed of 5.2 km/h gave the best results in all treatments. Therefore it is advisable to use the attached scalper that showed the best results for factories of sugar beet comparing the topping of sugar beet without scalper that raising the sucrose ratio and gave the good benefit. Also, the possibility of utilizing was studied under the Egyptian new reclaimed land and to suit large holding farms of investment companies using available facilities on farms. Field experiments were carried out to evaluate the performance of scalper at different forward speed, type of scalper and type of caliper. Scalping efficiency, yield of sugar beet, sugar ratio, power required and the cost of scalping operation were therefore studied. | ||||
