降落數值測定儀詳細介紹

一、產品介紹
降落數值測定儀(FN-II)是測定谷物中淀粉酶活性的專用儀器,可準確判斷谷物的發芽損傷程度,用戶可根據實際需要選擇帶打印和不帶打印功能。該儀器執行GB/T10361-2008《小麥、黑麥及其面粉、杜倫麥及其粗粒粉降落數值的測定法》標準,因此能夠被各類檢測機構所認同。

 

二、應用領域
降落數值測定儀適用于谷物、尤其是小麥粉的測定,是糧食貯藏、面粉加工、食品加工等領域。

 

三、儀器原理
谷物粉(如小麥粉)的懸浮液在沸水浴中迅速糊化,并因其中α—淀粉酶活性的不同而使糊化物的淀粉不同程度的被液化,液化程度不同,攪拌器在糊化物中下降速度不同,降落值的高低也就表明了相應的α—淀粉酶活性的差異。降落值愈低表明α—淀粉酶的活性愈高。降落值是以攪拌棒在糊化液自由下降一段特定高度所需的秒數來表示的。

 

四、儀器特點
1、采用微電腦控制,一鍵完成測試過程,無需人員看守。特有故障自檢功能。
2、面板人性化,簡潔大方,觸摸式按鍵,使用壽命長,測試過程窗口提示。

 

五、技術參數:(執行GB/T10361-2008《小麥、黑麥及其面粉、杜倫麥及其粗粒粉降落數值的測定法》標準)
攪拌棒重量: 25±0.05g 
水浴桶加熱管:600W
粘度管: 內徑21±0.02mm
