through a base plate. 一個正方形活塞對底盤上物體的向下擠壓力 。 2020 向下施力,使半固體順向擠出 FORWARD EXTRUSION: Measures the pression force for a “piston” disc to extrude a product through a standard sized outlet in the base of the container. 測試將樣品從容器底部的標準尺寸的開口處順向擠出的力量。 2020 BACK EXTRUSION反向擠出 : These tests work particularly well with viscous products such as: 這種測試特別適用于粘性物體,如: ?Soft Gels and yogurts 軟凝膠和酸奶酪 ?Fruit and Vegetable Purees 水果和蔬菜湯 ?Cosmetics 化妝品 ?Sauces and pastes 醬料和面糊 ?Greases 油脂 Negative area of graph caused by weight of sample on probe and adhesive characteristics. 圖表上的凹陷區(qū)是由于探頭上的樣品的重量和其具有的粘性特點導致的。有時也會量化穩(wěn)態(tài)下的平均壓力。在反向擠壓試驗中要說明的是面積 X和 Y。 ? Multiple blades make the cell particularly suited to the assessment of multiparticle products or those which have variable properties across their crosssection. 多刀片試驗單元特別適合于評估多顆粒產(chǎn)品或那些具有多種特性的物體,例如: ?Breakfast 早餐 cereals 谷類食品 ?Pie fillings 餅餡 ?Pastes 面食 ?

Peak force generated is of key interest. 模仿(人的)前面門牙撕咬的行為。 F t Initial fracture 破裂點 Gradual decrease in forces as fracture continues. Slower the decrease greater sample consistency . work to break Area is indicative of sample consistency WarnerBratzler Cut of a Sausage 香腸切割 變量 :探頭形狀和幾何尺寸(凹口刀片) Tel:02083510088,Fax:83510388 ?來自 中國最大的資料庫下載 東南科儀 2020 169。 CUTTING WITH A WARNERBRATZLER BLADE: A notched blade centrally locates cylindrical samples such as sausages. The notched shape gives increased contact area throughout the test generating more constant results. 切割實驗:將圓筒狀的帶有包膜的樣品如香腸放在一個帶凹口的刀片里。 meat products 肉類 ?Fish 魚 ?Vegetables 蔬菜 ?Cheeses奶酪 ?Cosmetics 化妝品 Tel:02083510088,Fax:83510388 ?來自 中國最大的資料庫下載 東南科儀 2020 169。 2020 變量 :探頭形狀和幾何尺寸(刀片) 向下施力,樣品被擠壓,進而被切開 CUTTING WITH A SHEAR BLADE: Blade fixtures are used to simulate the action of slicing or cutting. 用刀片切割:刀片夾具模擬切割行為。 2020 向下施力樣品被壓縮,進而破裂(松糕) SPHERICAL PROBES: Compression using rounded spherical ball probe. Probe es into contact with surface creating predominantly pression forces until point of rupture or end of test. 球形探針:向下接觸物體不斷產(chǎn)生壓力,直到樣品接觸點破裂或結束試驗。 2020 向下施力產(chǎn)生線切割,樣品被壓縮進而被切開 CUTTING AND SHEARING: As the blade or cutting wire es into contact with the samples cutting forces are generated as probe distance increases. 切割和剪切:刀片或切割線往下接觸樣品,當探針的距離增加時,產(chǎn)生切割力。 2020 變量 :探頭形狀和幾何尺寸(圓柱) 向下施力,凝膠狀物質(zhì)被壓縮和反向噴出 PUNCTURE AND PENETRATION: Probe es into contact with surface creating both pressive and shear forces as peration increases. 穿透試驗:探頭向下接觸樣品表面,當穿透力度加大時產(chǎn)生壓力和剪切力 GELATIN BLOOM TEST 凝膠試驗 Negative force = Tackiness of gelatin sample 反向力 F t Bloom value is taken as final force attained at given deformation BLOOM STRENGTH Area = Work to attain deformation Negative area = Adhesion of gelatin sample 反向面積 Tel:02083510088,Fax:83510388 ?來自 中國最大的資料庫下載 東南科儀 2020 169。 2020 Variables to Texture Analysis… 組織分析測量中可變的參數(shù) 質(zhì)構測定面對的是一些物體的自然性質(zhì)和形態(tài),可變性因素較多,為了測試準確,數(shù)據(jù)可用,我們必須保證相關因素的相對固定(溫度,濕度,夾具探針等) .
