關于菠蘿果實采用全自動快速研磨儀研磨提取脂肪酸的一種方法-上海凈信
第一段:背景知識介紹
陜西科技大學化工學院老師需要提取菠蘿果實中脂肪酸的含量,并進行下一步的科學研究,要求是將成熟的菠蘿果實切成片,在自然狀態下晾干或者是烘箱內烘干水分,使樣品呈干樣,然后研磨提取。眾所周知,菠蘿果實中糖分的含量較高,干樣在研磨過程中容易結塊,研磨難度增大,之前采用研缽手工研磨的方法,在研缽內倒入液氮,在凍干狀態下快速研磨,通常需要3次左右才能研磨,且研磨樣品不充分,實驗效果未達到預期,老師不是很滿意。現采用全自動快速研磨儀研磨的方法研磨菠蘿果實干樣。

第二段:描述一下樣品研磨原理
菠蘿果實干樣纖維及糖度含量較高,研磨時在液氮冷凍狀態下凍干樣品,采用鋼罐加鋼珠研磨
第三段:樣品具體研磨方法
實驗步驟:
步驟1:菠蘿果實樣品和的研磨鋼罐
步驟2 :將樣本放入鋼罐中,然后再將鋼罐放入液氮中浸泡幾分鐘,
步驟3:設置參數研磨頻率,時間設置好就可研磨成粉狀,
步驟4:從凈信研磨儀上取出樣本,將鋼罐打開倒出樣品。
實驗結果(放前后研磨對比圖)
研磨后樣品在液氮冷凍狀態下呈細小分散的粉末狀,一旦回復到常溫則立即粘附牢固粘在一起結塊,滿足實驗要求。
