秸秆膨化颗粒饲料生产工艺的研究

文章根据秸秆的利用现状以及畜牧业的要求,讨论了秸秆膨化颗粒饲料加工中的配方和工艺因素。研究表明,秸秆的膨化有助于物料的变性,能提高秸秆中的有用物质特别是粗纤维的吸收率;秸秆的颗粒化,有利于秸秆的充分利用,但是必须以谷物料原料作为粘结材料;秸秆的细化程度为16目、水分含量为35％-38％、秸秆干重含量为14％时,膨化效率较高;膨化后的颗粒饲料,有较好的抗压强度,有利于贮藏运输以及商品经营。

Study on the Producing Techniques of Straw Grain Granule Expanding Feed

According to the making use of straw and the requirement of stockbreeding, the techniques factors are discussed in this article. The experimentation was making-know: the expand- ing of straw make for it denaturalization, and it can improve the assimilating rate of usefulness substance in the straw, the thick fibre is marked; The grain of straw is favorable for it is used sufficiently, but it have to use the grain material to felt straw; When it is comminuted to 16 mesh, moisture 35%~38%, straw 14%, the Expanding effect is preferably; After expanding, It' s pressure intensity is higher, and it is propitious to store, transport and distribution.
