　　3、 乳(ru)(ru)化(hua)(hua)時(shi)刻(ke) 濕粉食(shi)品級高剪(jian)切乳(ru)(ru)化(hua)(hua)機的(de)(de)乳(ru)(ru)化(hua)(hua)時(shi)刻(ke)明顯對乳(ru)(ru)狀液的(de)(de)質(zhi)量(liang)有影響,而乳(ru)(ru)化(hua)(hua)時(shi)刻(ke)的(de)(de)斷定(ding),是(shi)(shi)要根(gen)據(ju)油(you)相水相的(de)(de)容積比,兩(liang)相的(de)(de)粘(zhan)度(du)及生成乳(ru)(ru)狀液的(de)(de)粘(zhan)度(du),乳(ru)(ru)化(hua)(hua)劑的(de)(de)類型及用量(liang),還(huan)有乳(ru)(ru)化(hua)(hua)溫(wen)度(du),但乳(ru)(ru)化(hua)(hua)時(shi)刻(ke)的(de)(de)多少,是(shi)(shi)為使系統進行(xing)充沛的(de)(de)乳(ru)(ru)化(hua)(hua),是(shi)(shi)與濕粉食(shi)品級高剪(jian)切乳(ru)(ru)化(hua)(hua)機的(de)(de)功率嚴密(mi)相連的(de)(de),可根(gen)據(ju)經歷(li)和(he)試驗(yan)來斷定(ding)乳(ru)(ru)化(hua)(hua)時(shi)刻(ke)。如用均(jun)質(zhi)器(qi)(3000轉/分鐘)進行(xing)乳(ru)(ru)化(hua)(hua),僅需用3-10分鐘。

　　4、 拌和速(su)度(du)(du) 濕粉(fen)(fen)食(shi)品級高剪切乳化(hua)機對乳化(hua)有很(hen)大(da)影響,其中(zhong)之一是拌和速(su)度(du)(du)對乳化(hua)的(de)(de)影響。拌和速(su)度(du)(du)適中(zhong)是為(wei)使(shi)油相(xiang)與水相(xiang)充(chong)沛的(de)(de)混合(he),拌和速(su)度(du)(du)過低,明顯達不到充(chong)沛混合(he)的(de)(de)意圖,但拌和速(su)度(du)(du)過高,會將氣泡帶入(ru)系統,使(shi)之成為(wei)三相(xiang)系統,而使(shi)乳狀液不穩定。因而拌和中(zhong)有必要防止(zhi)空(kong)氣的(de)(de)進入(ru),濕粉(fen)(fen)食(shi)品級高剪切乳化(hua)機具有很(hen)優(you)勝的(de)(de)性(xing)能(neng)。
