Abstract


In this thesis through the process of composite molding straw feed, determine the appropriate composite straw feed molding process and process parameters. At the same time, in-depth study of different dietary composition and traits, additives and their levels the composite straw feed molding effect. And fuzzy comprehensive evaluation model, a multi-factor fuzzy comprehensive evaluation of various processing programs. The results showed that: ① SYKH850 ring molded block, rough conditions of the feed water, the molasses, bentonite add and corn stover with alfalfa hay ratio, by adjusting the pressing of the 3 × 3cm ~ 2 specifications cattle and sheep composite straw molding like feed. The best composite straw diets molding process: roughage guillotine short, rubbing silk - → biochemical composite processing - → drying - → configuration concentrate feed - → mixed - → add Quenched - → briquetting - → dry cooling - → packaged . ② the forage ratio 4:6 ration water content was 21.48%, the highest molding rate is 90.36%, the maximum density for 861.63kg / m ~~ crushing best of 95.20 percent; granularity roughage preparation briquette density diets briquette molding highest rate of 91.35 percent, crushing maximum is 90.35; preparation of granularity roughage diets 885.63kg / m ~ 3; feed rate briquetting effect is basically no impact, but too fast will happen briquetting machine feed port blocking, too slow and too inefficient production. ③ With the increase in the amount of bentonite add, the molding rate of the block of material, the crush resistance were improved, the density is increased, but when the addition amount is too high, due to the increase the proportion of bentonite recipe lower nutrient concentrations, generally with 3% bentonite addition level is appropriate; molasses add molding rate, density and crushing the indicators had no significant effect, and with the increase of the added amount forming a weak trend of declines. ④ With dietary granulation effect of dietary forage to concentrate ratio increased gradually worse; the more likely the higher the level of crude protein diets briquetting; alfalfa hay than corn stover easy molding, when alfalfa hay completely replace corn stalks, the briquetting effect of the best. Primary and secondary relationship of the four factors ⑤ water, molasses add, amount of bentonite add, alfalfa hay and corn stalks proportion three indicators: water gt; bentonite added amount gt; ratio of alfalfa hay and corn stalks gt; molasses add volume and orthogonal tests predict forage to concentrate ratio of 4:6 TMR moisture content, amount of bentonite add, alfalfa hay and corn stalks proportions and molasses add the amount of 23%, 3%, molding effect test 25:35,1.5% best; quadrature variance by the three levels of multi-factor interaction analysis, the interaction between moisture content and particle size, particle size and the bentonite the interactions forming rate was not obvious, the moisture content and bentonite interaction molding rate, two factors Take level 3 as well. (6) through multi-level fuzzy comprehensive evaluation, this study, the 27 processing program judge the value of the top three, respectively: processing 24 processing 27, the process 21.
