“…In the uniaxial compression process, the force-deformation curve characteristics obtained from the compression process are used to determine the maximal compression force and deformation energy for recovering the oil from the bulk oilseeds and to understand the operational safety of the universal compression testing machine in terms of the undulation effect [27]. The above-mentioned processing factors, thus, influence the mechanical oil pressing process in large-scale production, which can be ascertained under the uniaxial compression process using an appropriate experimental design, such as the response surface methodology (RSM) coupled with the Box-Behnken design (BBD) [28][29][30][31][32]. The RSM is a collection of mathematical and statistical techniques useful for examining the effects of several independent factors [33,34].…”

Optimizing the operating factors in edible oil extraction requires a statistical technique such as a response surface methodology for evaluating their effects on the responses. The examined input factors in this study were the diameter of pressing vessel, VD (60, 80, and 100 mm), temperature, TPR (40, 60, and 80 °C), and heating time, HTM (30, 60 and 90 min). The combination of these factors generated 17 experimental runs where the mass of oil, oil yield, oil extraction efficiency, and deformation energy were calculated. Based on the response surface regression analysis, the combination of the optimized factors was VD: 100 (+1) mm; TPR: 80 °C (+1) and HTM: 60 (0) min); VD: 60 (−1) mm; TPR: 80 °C (+1) and HTM: 75 (+0.5) min and VD: 100 (+1) mm; TPR: 80 °C (+1) and HTM: 90 (+1). The absorbance and transmittance values significantly (p < 0.05) correlated with the wavelength and temperature, but they did not correlate significantly (p > 0.05) with heating time. The peroxide value did not correlate significantly with temperature, however, it correlated significantly with heating time. Neither the acid value nor the free fatty acid value correlated with both temperature and heating time. The findings of the present study are part of our continuing research on oilseeds’ processing optimization parameters.

“…Li et al [39] developed the WC-Ni-La2O3 on the steel using a laser cladding process. It was reported that an ultrasonic vibration device was used during the cladding process with different power [40][41][42][43][44]. The crack formation was investigated and reported on the propagation direction of a transverse crack within a composite coating and its interaction with the coating-matrix interface.…”

Mild steel is a popular material used in various applications due to its excellent machinability, strength and durability. Mild steel is one of the most affordable materials available, making it an excellent choice for budget-conscious projects. Regrettably, Mild steel is not typically used in some industries due to its low strength-to-weight ratio and limited corrosion resistance. AISI 1020 steel is relatively soft and has limited wear resistance compared to other types of steel, particularly those with higher carbon content. This review paper discusses the profitable and successful approach to enhance the service life and utility of the mild steel machinery components. Various investigators have put their effort into developing different methods to improve the properties of the mild steel components. The laser cladding process is developed by the melting of the preplaced coating layer with the surface of the substrate simultaneously which is able to prevent direct contact with the environment. The present review paper discussed in detail the impact of various parameters of laser cladding process and variation of the coating materials on the surface properties and microstructure of mild steel. Some challenges and remedies are also discussed in the paper. This review paper focused on some potential uses of the laser cladding process in diverse industries.

The purpose of this study was to evaluate the performance of Hohenheim Aceh type solar tunnel dryer with the application of proportional integral derivative (PID) controller for outlet fans. The instrumentations used were solar tunnel dryer type Hohenheim Aceh, HTC-meter, anemometer, pyranometer, and other supporting equipments. The results showed that during the drying process solar irradiation had fluctuated, where the average solar irradiation was 649 W/m 2 . The average temperature in the drying chamber is 40.6°C while the average temperature in the environment is 32.9°C. Conditions in the drying chamber were suitable for drying because the temperature inside the dryer was relatively higher than the ambient temperature. The average relative humidity (RH) in the drying chamber was 36% and the average RH in the environment was about 40%. The relationship between temperature and RH value was negative and strong indicated bu r-value of 0.7379. On the other hand, the relationship between solar irradiation and temperature was positive and also strong indicating that the energy source for this dryer was from solar irradiation with an R-square of 86.02% and r-value of 0.92747. The application of PID controller had improved the performance of Hohenheim Aceh type solar tunnel dryer by preventing the incident of unproper drying temperature. However, the airflow in the drying chamber was too low thus the further engineering design is needed to improve the drying system.
