“…As an example, the stress on a certain member is P/A (where P is the applied load and A is the cross-sectional area), regardless of the material. Evelien Uitterhaegen et al 2017 [8] Vegetable oils present a valuable class of bioresources with applications in both food and nonfood industries and a production that has been steadily increasing over the past twenty years. Their extraction from oilseeds is a key process, as it exerts a strong impact on the resulting oil characteristics and quality.…”

Extruded rubber is used extensively in many applications and products, either alone or in combination with other materials. It is often desirable to find the best possible way to maximize the production output with least possible capital input and changes in existing plant layout. The changes that are permitted are in the department of pre-processing that is designing stage and machine selection. The proper design of an extrusion die is extremely important to achieve the desired shape and accurate dimensions of the extruded product also to ensure that production level will produce maximum profit and lead minimum cost. The increase in productivity can be defined as the effectiveness of productive effort, especially in industry, as measured in terms of the rate of output per unit of input. Here the productivity is considering the re-designing of single cavity die to multi-cavity die, the die is a metal block that is used for forming materials like sheet metal, plastic, rubber, etc. The scope of current study takes into consideration of re-designing the most commonly used design of rubber extrusion die with a single cavity and would evaluate the effect of introducing the design of double cavity design on the overall increase in productivity of the industry. After redesigning the die for rubber extrusion moulding we would compare the statistical data of existing output data for productivity and hence the other changes required to keep up the increased productivity rate.

“…It produces relatively uncontaminated oil without using any chemical reagent and is considered a healthier method compared to the solvent extraction process (Leticia et al, ; Olajide et al, ; Sorin‐Stefan, Ionescu, Voicu, Ungureanu, & Vladut, ). Uitterhaegen and Evon () pointed out that, in view of the recent pressure toward sustainability, oilseed‐processing industries are taking renewed interest in thermomechanical pressing as a means to obtain high‐quality oils. Although mechanical methods have such a great advantage of producing high‐quality oil as well as other advantages like low initial costs and easy operation (Leticia et al, ), they still have the shortcomings of low yield (Ogunsina, Olatunde, & Adeleye, ; Sorin‐Stefan et al, ).…”

Mechanical pressing is widely used for producing high‐quality vegetable oil in industry. However, mechanical pressing process faces a challenge from meeting the industrial demand for high yield with low energy consumption. Hence, the objective of this study was to optimize mechanical oil extraction process from Camellia oleifera seeds by maximizing the yield and minimizing the energy consumption. A Box–Behnken design of response surface methodology is adopted for the experiments of mechanical oil extraction from C. oleifera seeds. The effects of experimental factors namely moisture content (0–9% w.b.), applied pressure (10–45 MPa), pressing temperature (40–100°C) and extraction time (10–40 min) on yield and energy consumption were investigated by modeling the oil extraction process. An analysis of variance (ANOVA) revealed that moisture content, applied pressure and extraction time significantly effect on yield while applied pressure, pressing temperature, and extraction time have an obvious influence on energy consumption. In addition, the oil extracted under the processing conditions investigated was validated to be of acceptable quality. The Pareto fronts based on multiobjective genetic algorithm provides a set of optimal process parameters to obtain sustainable end products. Practical Application Moisture content, applied pressure, pressing time, and pressing temperature are primary processing conditions affecting oil extraction from C. oleifera seeds during the mechanical process. The use of inappropriate processing parameters may lead to low yield and high‐energy consumption. Understanding the mechanisms of oil extraction process thoroughly while taking important parameters into consideration is vital for the process to be efficient. This can be obtained by modeling oil extraction process using both experimental and theoretical methods. In this article, how these factors affect the yield and energy consumption of the system were investigated by modeling the oil extraction process. Processing conditions were optimized by multiobjective optimization technique based on NSGA‐II. The oil extracted under the processing conditions investigated was of acceptable quality. The data collected during this study can be utilized to design the equipment and to obtain sustainable end products.
