【摘要】：试验对山羊全混合日粮颗粒饲料加工技术与生产工艺进行了研究。结果表明,不同原料及不同精粗比混合饲料用压缩比4.71的平模颗粒机制粒,配方中无草粉的混合饲料、纯草粉等制粒成型率达到97.39%以上。单一的草粉较混合草粉更容易制粒成型,玉米秸秆粉较花生藤粉更易制粒。含草粉的混合饲料制粒成型率34.92%~89.71%,成型率随精粗比增大而提高。小麦、膨润土等原料对含草粉的混合饲料成型率没有明显的改善。油菜籽对羊全混合饲料制粒成型没有显著影响。用于生产畜禽料的颗粒机压模(压缩比4~51)不适宜于生产羊全混合饲料,平模压模板压缩比提高到61时,制粒成型率明显提高,可达到96%以上。环模颗粒机环模压缩比设计为81时,制粒成型率可达到92.85%~96.68%;使用专利技术设计的环模,制粒成型率可达到99%以上。草粉细度选用4 mm粉碎机筛板为宜。混合时间以6 min为宜。在加工工艺上,草粉加工环节设置合理的缓冲仓,缓冲仓内设震动棒以防拱阻,促进流动,输出采用螺旋机械输送;配料输送草粉采用大口径螺旋提升机或皮带输送机;制粒环节配置制粒缓冲仓提高生产效率;对喂料设施及喂料口控制件设计保证喂料均匀性,准确控制喂料速度。
[Abstract]:The processing technology and production technology of goat total mixed diet pellet feed were studied in this paper. The results showed that the granulation rate of flat mold granule with different raw materials and different ratio of concentrate to coarse was 4.71, and the granulation rate of pure straw powder was more than 97. 39% for the mixed feed without grass powder in the formula, and the granulation rate of pure grass powder was more than 97. 39% for the mixed feed with different raw materials and different ratio of concentrate to roughage. Single straw powder is easier to granulate than mixed grass powder, corn straw powder is easier to granulate than peanut rattan powder. The granulation rate of mixed feed containing grass powder was 34.92% and 89.71%, and the molding rate increased with the increase of the ratio of fine to crude. Wheat, bentonite and other raw materials have no significant improvement on the formation rate of mixed feed containing grass powder. Rapeseed had no significant effect on the granulation of sheep mixed feed. The granulator pressing die (compression ratio 4 鈮，
