Abstract
bstract
Sugar cane mills are the equipment used in extracting sugar solution from sugar cane plant.
mills engineers work on developing the performance of cane sugar mills to increase their efficiency by improving extraction to obtain more sugar solution and at the same time reduce the amount of sugar lost in the bagasse.
Most of the research done in this study was represented in developing the design of rollers mills by making longitudinal channels along the roller in order to reduce the amount of absorption of the sugar solution during and after the pressing process of the bagasse exit from the mills.
The effect of the difference rollers pitch in the three rollers mill has not been studied, E.Hogut indicated on his handbook of cane sugar engineering that the extraction mills by small pitch rollers is better than the large pitch rollers possibility using of the combined two difference rollers pitch in the millto increase performance and extraction efficiency of mills.
In this study the effect of the roller pitch has been studied as one of the constituent parts of the mills by modifying the universal roller pitch to the triple roller pitch compound on Czech Skoda mills which located in the Deshna sugar factory and experimenting with extracting different sugar cane weights. On both mills , universal and triple compound pitch on the mills rollers under the same conditions and control of the correct setting taking into account with the uniformity of samples and it was recorded the results were positive by increasing the weight of the squeezed sugar cane in the three - pitch compound rollers mills of extracted juice which increasing percentage up to 3.02 % in contrast to the extraction of single pitch rollers mills which was positive only on low weights.
By increasing the extracted juice from the sugar cane plant we will have achieved an increase in the raw material used in the sugar industry which helps to increase the amount of sugar produced.
