Vegetable oils are extracted from the vegetable sources and it is mainly used for human consumption in the form of food products. The modern way of extracting the vegetable oil is by using solvent extracts. Anyway, vegetable oil press is mainly used to extracts oils from the raw vegetable resources by crushing those resources into the machine. This technique is mostly adopted by the upcoming industrial oils, who extract oil from soybeans and corn. The other way which is predominantly followed by many is by physical extraction which doesn’t require any solvent extracts. The vegetable oils can be derived from the following sources
- Palm
- Soybean
- Rapeseed
- Sunflower seed
- Peanut
- Cottonseed
- Coconut
- Olive
Soybean, corn, sunflower oil etc. contains omega – 6 polyunsaturated fatty acids, so if it is consumed higher, then it might result in some diseases whereas the oils like coconut, palm oils are high in saturated fatty acids which can be consumed without much worries.
Different vegetable oil press machines will have different specifications and the press worms in size and length, so it needs to be set accordingly to get the oil squeezed out properly. Some automatic oil press machines needs the press chamber, press screw and the press rings to be pre-heated since the oil need to be processed at a certain temperature
