PERFORMANCE EVALUATION OF WHEAT STRAW CHOPPER BLOWER

performance evaluation of the cutter unit of a straw chopper

a prototype of a straw chopper, equipped with a discharge system was designed and fabricated in the department of mechanics of agricultural machinery, university of tehran, karaj, iran. to test for the effective performance of the machine, the effects of such parameters as: drum speed (at three levels of: 400, 540, and 800 rpm), screen size (at two levels: 2.5 and 4 cm), and number of blades on...

The effect of wheat straw bleaching on some mechanical properties of wheat straw/LDPE biocomposites

Using biocomposites containing wheat straw (WS) and synthetic polymers like polyethylene (PE) has gained tremendous popularity, but its application in the packaging industry is not substantial. Due to the prevalence of raw WS color which manifests itself in the WS/LDPE biocomposite, the present investigation is dedicated to fabricate a bleached WS/LDPE composite. Thus, raw WS and the pulp of WS...

Chemical Treatment of Wheat Straw

Evaluation of the Nutritional Value of Ammoniated Wheat Straw by Anhydrous Ammonia in Fattening Calves Feeding

Extended Abstract Introduction and Objective: Processing of agricultural by-products for animal feed can upgrade the supply of animal feed without increasing the current production and only by improving productivity via enhancing energy efficiency and maintaining it in the food supply chain, and at the same time, diminish the concerns of waste management, food security, resource constraints, a...

Effect of Feeding Dietary Treated Wheat Straw with Urea and Whey on Fattening Lambs Performance

This study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. About 4.5 kg urea and 1.5 kg salt were dissolved in 40 L water and mixed with 30 L of whey. The solution was spread over 100 kg chopped wheat straw. Thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...
