Furthermore,the feeding zone having an enough covering length of grooved bushing work successfully out transport of the special soft oilseed with high oil content and low crude fiber content without other forced feeding sets.
The feeding zone with a grooved bushing can work successfully out transport of the special soft oilseed with high oil content and low crude fiber content without other forced feeding sets.
In order to develop the extrusion cooking process conditions of the coarse grain nutrition breakfast cereals, the extrusion expansion temperature, the moisture content, the screw speed and the feeding rate were studied and the optimized parameters were obtained.
The axial pressure distribution in the whole process of rubber cold - feed extrusion was analyzed. The axial pressure in the screws was measured and imitated.
The influence of frictional factors on solid conveying ratio(Q)of rubber cold -feed ex-trusion was analyzed by theory and ex periment. The influence of the temperature of feed-section(T b ),screw speed,physical performances of the stocks on Q was discussed. The length of feed -se ction was calculated.
A trinomial equation for output-pressure decrease was deduced by the simple trilamina model of non-plug solid conveying and stress-velocity equation based on the non-plug solid conveying theory in single-screw extruder.
The results show that increasing covered length of the feeding screw and friction coefficient inner the barrel can raise pressure at the feed end and capacity of press.
A mathematical model was proposed for the characteristics of solid transportation in the feeding zone of an intermeshing co-rotating twin screw extruder.
This paper also suggests a solution for the mathematical expressions describing the stress and velocity fields in the solid feeding zone of a twin-screw extruder.
The interpretation of the non-uniform enrichment in C, N and S in Saturn requires that ice was less abundant at 10 AU than at 5 AU so that CO and N2 were not clathrated in the feeding zone of the planet while CH4, NH3 and H2S were.
A model for the conveying of solid polymer in the feeding zone of two rotors continuous mixer was proposed. The model enable us to predict the production of continuous mixer. It was concluded that the production of continuous mixer had a direct relation to feeding rate, but was out of relation to rotating speed of totor.
The axial pressure distribution in the whole process of rubber cold - feed extrusion was analyzed. The axial pressure in the screws was measured and imitated. The reason of hungry - feed and back -feed was analyzed also. The results indicateed that the distribution function of pressure along the axis was almost exponential function, the hardness, viscosity andtensile strength of the stocks not only influenced the axial pressure but also were important factors forming hungry - feed and back - feed. Fluctuati...
The influence of frictional factors on solid conveying ratio(Q)of rubber cold -feed ex-trusion was analyzed by theory and ex periment.The influence of the temperature of feed-section(T b ),screw speed,physical performances of the stocks on Q was discussed.The length of feed -se ction was calculated.The effects of friction al factors and the performance of the stocks on feed -efficiency were analyzed synthetically.The results indicated that T b had an effect on friction between rub ber stock andb...
