真空干燥器的特点是由于它能在低温印温度为100F左右除去液体,并可将该液体回收,如果干燥的物料是热敏的,或者所除去的溶剂是昂贵的,那就应该考虑用真空干燥器。

Poultry meat production steadily increases and its by-products including legs or skins may be further utilized to prepare gelatine,generally by using alkali or acid substances.Since they are toxic,different methods are desirable,e.***.applying proteolytic enzymes.Using enzymes is beneficial as they shorten processing time and reduce the required water amount.Processing conditions(the enzyme amount during the pre-treatment,first and second extraction temperature and time)of the process may influence gelatine quality and its yield.In this study,gelatines were prepared from chicken skin at different conditions in the series of combined factorial design of experiments.The significance of the influence of the conditions on the quality(gel strength,viscosity,melting and gelling point)and yield of chicken skin gelatine(CSG)was observed.The highest yield(31.5%)was obtained at the conditions of the enzyme amount of 0.8%,first extraction temperature 80℃ and time 30 min,second extraction temperature 90℃ and time 60 min.Furthermore,the highest CSG quality of gel strength(190 Bloom),viscosity(4.06 mPas),melting point(38.3℃)and gelling point(20.5℃)was obtained at the conditions of 0.2%/50℃/30 min in the first extraction.

Change in the temperature of band over its length, associated with the stock being non-uniformly heated in the furnace, influences the variations in the magnitudes of energy-force parameters. Using the FEM (Finite Element Model) programs for the computation of the values of the energy-force parameters can take into account the distribution of temperature over the band length. The mathematical model of the computer program Forge2008 was used to theoretically examine the energy-force parameters and plastic metal flow in the roughing stands of the continuous rolling mill. The results of experimental investigation of influence of the non-uniform temperature distribution were presented on the metallic charge length on the energy and force parameters and dimensions of the band during round bars rolling. Thermovision monitoring energy and force parameters monitoring were carried out in continuous rolling mill D350 in one of the Polish industrial plants. On the basis of obtained results, it could be stated that non-uniform distribution of temperatures along the charge length causes local increase of energy and force parameters values and also such distribution affects the local increase of the width of rolled band. The rolling process of charge with non-uniform distribution of temperature could lead to exceeding required dimensional tolerances of the final products.

A procedure for evaluating the susceptibility of raw materials for the process of sintering of iron ore mixes is presented. The procedure relies on the evaluation of the amount and quality of the finest grain fraction. The method is based on determination of particular grain fractions. For the grain less than 0.15 mm, the determination of the a- mount is performed using an IPS （Infrared Particles Sizer） grain size analyzer and for the grain larger than 0.15 ram, the fraction is determined using the （wet and dry） screening methods. This allows for quantity assessment of the quality of material in terms of its susceptibility to self-pelletizing by calculating Total Ability for SelPPelletizing （TASP） index fT. The presented method, in combination with the grain size and chemical analyses, can serve for evaluation of suitability of raw material and mixes for the sintering process. Furthermore, the TASP index for 10 types of iron ores and concentrates was determined. The usability of the TASP index was verified by determination of its impact on yield of sintering process both in laboratory and in industry scale.

Determination of chemical elements assay plays an important role in mineral processing operations.This factor is used to control process accuracy,recovery calculation and plant profitability.The new assaying methods including chemical methods,X-ray fluorescence and atomic absorption spectrometry are advanced and accurate.However,in some applications,such as on-line assaying process,high accuracy is required.In this paper,an algorithm based on Kalman Filter is presented to predict on-line XRF errors.This research has been carried out on the basis of based the industrial real data collection for evaluating the performance of the presented algorithm.The measurements and analysis for this study were conducted at the Sarcheshmeh Copper Concentrator Plant located in Iran.The quality of the obtained results was very satisfied;so that the RMS errors of prediction obtained for Cu and Mo grade assaying errors in rougher feed were less than 0.039 and 0.002 and in final flotation concentration less than 0.58 and 0.074,respectively.The results indicate that the mentioned method is quite accurate to reduce the on-line XRF errors measurement.
