| Abstract: |
| Nowadays, spiral presses have become very popular due to higher extraction efficiency and higher quality oil. Due to high pressure and friction between the seeds during oil extraction, heat is produced. The problem that exists during the use of the press is the heat excessive increasing, which leads to a decrease in the oil quality. In the spiral press, controlling the oil extraction temperature is a essential factor for high quality oil. Therefore, in order to keep the temperature constant, an automatic temperature control system was designed and built. Then oil extraction from Moringa peregrina seeds was done at three temperatures of 40, 50 and 60 degrees Celsius and the temperature rate of the press in each process was recorded by the data collection system. In this research, the heat transfer simulation of the cooling system of the spiral press was done using ANSYS-CFX software. The temperature distribution of the press was checked at three temperatures of 40, 50 and 60 degrees Celsius, and its values were obtained by simulation and experimental method. In order to validation, the results of the simulation method were compared with the experimental method, which had proper accuracy. Oil extraction at 60 degrees Celsius had the lowest validation error of 4.1%. Therefore, considering the low difference in the results of these two methods, the high cost and Time-consuming of the experimental tests, the simulation method can be considered a suitable and reliable alternative for the thermal analysis of the cooling system of the spiral press. |
