关于菠萝果实采用全自动快速研磨仪研磨提取脂肪酸的一种方法-上海净信
第一段:背景知识介绍
陕西科技大学化工学院老师需要提取菠萝果实中脂肪酸的含量,并进行下一步的科学研究,要求是将成熟的菠萝果实切成片,在自然状态下晾干或者是烘箱内烘干水分,使样品呈干样,然后研磨提取。众所周知,菠萝果实中糖分的含量较高,干样在研磨过程中容易结块,研磨难度增大,之前采用研钵手工研磨的方法,在研钵内倒入液氮,在冻干状态下快速研磨,通常需要3次左右才能研磨,且研磨样品不充分,实验效果未达到预期,老师不是很满意。现采用全自动快速研磨仪研磨的方法研磨菠萝果实干样。

第二段:描述一下样品研磨原理
菠萝果实干样纤维及糖度含量较高,研磨时在液氮冷冻状态下冻干样品,采用钢罐加钢珠研磨
第三段:样品具体研磨方法
实验步骤:
步骤1:菠萝果实样品和的研磨钢罐
步骤2 :将样本放入钢罐中,然后再将钢罐放入液氮中浸泡几分钟,
步骤3:设置参数研磨频率,时间设置好就可研磨成粉状,
步骤4:从净信研磨仪上取出样本,将钢罐打开倒出样品。
实验结果(放前后研磨对比图)
研磨后样品在液氮冷冻状态下呈细小分散的粉末状,一旦回复到常温则立即粘附牢固粘在一起结块,满足实验要求。
