Abstract

The present experiment has been conducted to evaluate of some economic indicators of hulling and bleaching machines of cultivar rice ,Tarm Hashemi in the laboratories of the University of Tehran to 2015. Recerch has include use of two types of machines Satake and Yanmar, under three levels of moisture conten of grain, 10-12% , 12- 14% and 14-16%),and three levels of clearance between cylinders 0.4 , 0.6 and 0.8 mm. The results indicated that the machine type Satake is significantly better on the machine type Yanmar in all studies factors. When increase grain moisture content leads to an increase the costs ,while when increase clearance among cylinder leads to a decrease the costs to all studied traits. The overlap between the machine type Satake and moisture content of grain 10-12% is superior significantly and also overlap between the machine type Satake to clearance 0.8. in all studied factors as compared with the machine type Yanmar with moisture content of grain and two clearance 0.4 mm in all studied factors. The best results have come from the triple overlap among machine type Satake, grain moisture 10-12%, and clearance 0.8 mm in all studies factors.

اجريت التجربة لتقيم بعض الصفات الاقتصادية لمكائن التقشير والتبيض الرز صنف تارم هاشمي في مختبرات جامعة طهران لعام 2015 تضمن البحث دراسة نوعين من المكائن Satake و Yanmar تحت تاثير ثلاث مستويات من رطوبة الحبوب 10-12%, 12-14% و 14-16% وثلاث مستويات من الخلوص بين الاسطوانات 0.4 ,0.6 و 0.8 ملم . أظهرت النتائج تفوق نوع المكائن Satake معنويا على نوع المكائن Yanmar في جميع الصفات المدروسة . عند زيادة رطوبة الحبوب أدى الى زيادة نسبة التكاليف بينما عند زيادة الخلوص ادى الى انخفاض التكاليف . التداخل بين نوع المكائن Satake ورطوبة الحبوب 10-12% كان معنوي وكذلك التداخل بين نوع المكننة Satake والخلوص 0.8 ملم ايضا كان معنوي في جميع الصفات المدروسة مقارنة بالتداخل بين نوع المكائن Yanmar مع رطوبة الحبوب والخلوص 0.4ملم . افضل النتائج كانت عند نداخل نوع المكائن Satake ورطوبة الحبوب 10-12% والخلوص 0.8ملم .
