【摘要】：為干燥人參-丹參提取液以及提高產(chǎn)品的吸收率,運(yùn)用噴霧干燥法對(duì)人參-丹參提取液進(jìn)行了干燥處理。在單因素試驗(yàn)的基礎(chǔ)上,以提取液密度、進(jìn)口溫度、泵速(進(jìn)料速率)為影響因素設(shè)計(jì)了L_9(3~3)正交試驗(yàn),正交試驗(yàn)分析得到噴霧干燥法制備人參-丹參提取液粉的最佳工藝條件為:提取液密度為1.05 g/m L、進(jìn)口溫度為140℃、泵速為10%。掃描電鏡檢測(cè)結(jié)果證實(shí)普通干燥后研磨的人參-丹參提取液粉顆粒形狀不規(guī)則,粒徑較大,并且顆粒大小不均,而噴霧干燥制備的人參-丹參提取液粉顆粒呈規(guī)則的球狀,粒徑較小,并且更加均勻;這都有利于產(chǎn)品后續(xù)的工業(yè)化生產(chǎn)以及提高食用后的消耗吸收率。
[Abstract]:In order to dry ginseng-salvia miltiorrhiza extract and improve the absorptivity of the product, spray drying method was used to dry ginseng-salvia miltiorrhiza extract. On the basis of single factor test, L9 (3 / 3) orthogonal test was designed based on the influence factors of extraction liquid density, inlet temperature and pump speed (feed rate). Orthogonal test showed that the optimum conditions for preparation of Ginseng-Salvia miltiorrhiza extract powder by spray drying were as follows: the density of extract solution was 1.05 g / mL, the inlet temperature was 140 鈩，
