Sunflower oil production line is featured of low energy consumption, less manpower, high oil output and easy maintenance. With automatic crushing and pressing system, this sunflower oil production line machines are used for various raw materials, such as: ground nuts, rice bran, sesame, olive, sunflower, coconuts and cocoa and grass seeds. They are widely used in medium-small sized oil extruding workshops or professional farmers. The whole production line includes crushing machine, conveyor and oil pressing machine. The main equipment is oil pressing machine which is a new research improvement product. This kind of machine adopts micro-electrical control, filter system, multi-stage press and cold and hot press. At present, sunflower oil production process have two kind of processing method: pressing and leaching(extraction). Pressing method is by physical pressure and get oil directly from the oil seeds. The whole process does not involve any chemical additives, to ensure product safety, health, pollution-free. The expeller method is divided into cold pressing and hot pressing. The difference of cold pressing and hot pressing is whether use high-temperature process or not. Hot pressing using a high temperature, can improve the oil yield, but destroy nutrients; cold-pressed not to use high temperature, the oil is low, but the complete nutritional ingredients. The product oils the clean oil after filtering, it can directly to use. The machine is the most ideal equipment for individual processing.
