| Abstract: |
| When screw press was used to produce oil, oilseeds was preheated through auxiliary heating of the press cage. For auxiliary heating mode, the simulation method was adopted to backward prediction by temperature of the cage outer surface to solve temperature of cage inner surface, which provides reference for process of preheating. The simulated temperature and measured temperature of the cage outer surface were compared. The error was in the range of -3.5%-5.5%, which indicated that the simulation method could be applied to predict auxiliary heating process. Appling this method, temperatures of the inner cage surface ranged from 55.4?℃ to 87.3?℃ in the main squeezing part, which satisfied the preheating treatment of oilseeds by screw pressing process. |
