Coconut oil (Cocos nucifera L.) has a unique role in the diet as an important physiologically functional food. The health and nutritional benefits that can be derived from consuming coconut oil have been recognized in many parts of the world for centuries. Optimization has found several applications in various processes widely used in the food industry and other industrial applications. In this study, the mechanical oil expression process for coconut was optimized using Response Surface Methodology. Experimental factors were moisture content, heating temperature, heating time and pressing time. Data analyses were done using multiple linear regression at p = 0.05. Predicted optimum conditions were validated using experimental values. Highest oil yield of 43.78% was obtained at moisture content of 14%, temperature of.........

Keywords - Coconut oil, response surface methodology, optimization, oil yield.

Energy conservation and environmental protection has become the most important and eternal theme in the world.Compressor industry as the pillar industry of national economic life, its response to the slogan of energy saving is even more urgent.In this study, the retrofit design of screw compressor unit, such as adding frequency converter and optimizing pipeline, is analyzed by numerical calculation, and the performance of some aspects of screw compressor unit after retrofit design is preliminarily estimated.The results of this study will provide direction and theoretical basis for the subsequent energy-saving renovation design of screw compressor unit.

Keywords - Screw compressor unit;Transformation design;Piping design.
