G1 4 2型浆纱机采用弹簧加压方式控制压浆力,调节压浆力只能凭经验进行调节,经常出现压力过大、过小或同一压浆辊两端压力不一致的问题,而且加压弹簧经长期使用后还会出现压力减小的现象,造成加压不准确。我们经过反复研究,设计出一套改进方案,能取得如下效果:可对前、后压浆辊设置不同压力,在浆纱机低速时配合低压力,高速时配合高压力,前压浆辊可设置低压浆力P1 、高压浆力P2 ,后压浆辊可设置低压浆力P3、高压浆力P4四种压力,并且在突然停电时还会利用余压使压浆辊自动抬起。改造后的电气控制原理图见图1。图1 电气控制原理图图1中SA1… 相似文献

Squeezing Flow Viscosimetry of Peanut Butter 总被引:3,自引:0,他引:3
The rheological characteristics of peanut butter were determined in two types of lubricated squeezing flow tests, one based on constant deformation rate and the other on deformation under constant stress (creep). Elongational flow was observed in both types of tests. When the flow regime was not governed by viscoelastic effects, peanut butter could be described as a power law fluid with consistency on the order of 70–200 KPa and flow index of 0.5–0.7. 相似文献

In most conventional rheometers, notably the coaxial cylinders and capillary viscometers, the food specimen is pressed into a narrow gap and its structure is altered by uncontrolled shear. Also, most semiliquid foods exhibit slip, and consequently the measurements do not always reflect their true rheological properties. A feasible solution to these two problems is squeezing flow viscometry where the specimen, practically intact and with or without suspended particles, is squeezed between parallel plates. The outward flow pattern mainly depends on the friction between the fluid and plates or its absence ("lubricated squeezing flow"). Among the possible test geometries, the one of constant area and changing volume is the most practical for foods. The test can be performed at a constant displacement rate using common Universal Testing Machines or under constant loads (creep array). The tests output is in the form of a force-height, force-time, or height-time relationship, from which several rheological parameters can be derived. With the current state of the art, the method can only be applied at small displacement rates. Despite the method's crudeness, its results are remarkably reproducible and sensitive to textural differences among semiliquid food products. The flow patterns observed in foods do not always follow the predictions of rheological models originally developed for polymer melts because of the foods' unique microstructures. The implications of these discrepancies and the role that artifacts may play are evaluated in light of theoretical and practical considerations. The use of squeezing flow viscometry to quantify rheological changes that occur during a product's handling and to determine whether they are perceived sensorily is suggested. 相似文献
