How to be Successful with the Solvent Extraction Process

Solvent extraction is a technique in which materials are processed through the removal of solvents to separate components in those materials. Generally it is used in liquid materials but can be used for gases and solids. Solvent extraction is common in the oil refining process. For example, when petroleum is processed, there are still impurities in it so solvents are added to the petroleum and then extracted from it. The result is cleaner and efficient petroleum that can be sold and used.

Solvent ExtractionChoosing The Right Solvents

In order to have a successful solvent extraction process, the right solvents must be used. A good solvent has to be able to eliminate at least one compound in the oil and it should also be irreversible because reversible solvents can return the old compounds back to the oil. The solvent should be free of harmful toxins.

Jobs That Involve Solvent Extraction Process

Chemists often work on projects that involve solvent extract and the same is true of chemistry college students who do experiments in the laboratory. This is why it is important for those who are involved in solvent extraction to take safety procedures so they will not harm their bodies. Those who work for perfume manufacturers may also use the solvent extraction process.


Solvent extraction process is essential in the oil refinery business and in other industries that are centered around chemicals. It is sometimes difficult to understand if you are not into scientific topics and if you need a simple understanding of it, you can purchase books that offer understandable information.

Preparation of seeds for oil press

After learning how to use an oil press, it is very important for you to know how to prepare the seeds for oil pressing. Seed oil press will only be successful if you prepare the seeds well in order for you to finally, have your vegetable oil. The process of cleaning seeds actually varies depending on the type of seeds you are using. Generally, there are only two steps involved in cleaning of seeds and you will find them to be quite simple once you learn how to do it.

Preparation of seeds for oil press

First, take off the hulls or seed coats from the seed. The hulls should not be thrown away because the hull of some seeds could be very useful. Take for instance the hulls for sunflower and soy are used as an additive to animal feed. Secondly, separate the seeds from chaff. Several methods are used for this process. The two steps can be carried out using some devices and there is a wide range of technologies for the above.


Seeds to be used in seed oil press process need to meet certain conditions. The most important thing that is compulsory is for the seeds to be thoroughly clean. This is because the process of getting oil from the seeds uses machines, which are prone to damage in case they come into contact with dirt. Some people think that it is only stones and large particles of dirt that can damage the machines but any type of dirt or sediment can cause damage to.


Besides, the seeds should be separated from chaff totally, so that the process of oil absorption goes on smoothly. The seeds to be used must be dry to prevent the machinery from clogging. Besides, use of moist seeds will lead to decrease in yields of oil. The seeds used have to be warm if you want to get the right amount of oil from them. The actual temperatures required should be between 100 and 160 degrees Fahrenheit.


It is possible to achieve this temperature using various means. You can use an oven, double boiler, or solar collector to warm small amount of seeds. On the other hand, for large amounts of seeds, use a heated hopper. It is important to note that all of the above conditions must be met in order for you to get the right yield of oil for a given amount of seeds.

Oil Press Screw

Oil press screw is very crucial in the oil extraction process. The seeds are placed in the pressing chamber through the hopper before the process begins. Here, the spiral turn works by squeezing the seeds. The chamber gets into high pressure and the screw squeezes the seeds to generate oil. There are bars around the screw or the commonly known, worm shaft which squeezes the seeds. The screw has tiny gaps in between and oil passes through these holes. Pressure forces the slow moving screw to crush the seeds as the force is applied on the bars moving forward to the exit plug. The plug is flexible and can be adjusted to suit the pressure required on the seeds.
Oil Press Screw
Heat is produced as pressure builds within the screw bars. The heat may be regulated to low temperatures to ensure the oil produced is pure and full of nutrients. This is because heat on the oil will burn out some nutrients from the oil. The screw oil press has a simple design which is easy and safe to operate. It is made with quality carbon steel and cannot wear or tear easily. It is able to work in any kind of temperature and pressure effectively.
