Pressing Oil from Seeds: The Recipe For A Sustainable Lifestyle

Pressing oil from seeds – is it difficult? Such a simple machine as a seed oil press can be a great example of how innovation can be used to create a more sustainable lifestyle.

This article will explore this fantastic idea of pressing oil from seeds, its origin, and the equipment behind it.

The most common oils that can be extracted are flaxseed oil, olive oil, coconut oil, hemp seed oil, sunflower seed oil, etc.

What Happened In Mesopotamia?

Did you know that pressing oil from seeds has been practiced for thousands of years? That’s right! The earliest records of oil extraction date back to 4500 BC in Mesopotamia, when they used stone presses to produce olive oil.

From there, we have seen many different innovations across regions and cultures on how to get more oils from seeds by pressing them.

In a region where the sun shines nearly 300 days a year, and dry heat can get as hot as 104 degrees Fahrenheit, it’s not surprising that many locals have turned to harvesting the abundant natural oils found in seeds like olives, almonds, and soybeans.

Nowadays, these oils are pressed from these seeds to create a range of products used for cooking, cosmetics, and even biofuel.

From an old stone press to modern industrial operations, these mills work hard every day to extract oil from these local plants. From raw nuts or olives that have been crushed to release their buttery juice, these oils are everywhere!

There’s no getting away from oil in today’s world. From cooking oils to skincare oils, there are many different kinds. They all have their own uses and benefits.

However, not all oils are sustainable.

While some types of oil can be sourced ethically and sustainably, others cannot be produced sustainably at this time.

Read on to find out more about the different kinds of oil, sustainability, and how you can use them as part of a sustainable lifestyle.

How Do You Press Oil From Seed?

– Can seed oil be cold pressed?
– How do you extract oil from nut seeds?
– How do you cold press oil from plants?

These are some of the most common questions that keep popping up whenever people want to make their own natural oils at home.

Whether you are a seasoned DIYer or it’s your first time experimenting with oils, these questions might cross your mind. In this article, we will answer some of these questions to help you get started with seed oils in the best way possible.

Pressing Oil from Seeds – Methods of Extraction for Seed Oils

There are several methods of extraction for seed oils, which can impact the nutrient profile. The most common forms of processing oil from seeds are:

– cold pressing
– expeller pressing
– mechanical pressing
– solvent extraction

Cold pressing is the most common method of extracting all types of oils, including vegetable oils. The raw material is crushed and then pressed to extract the oil using this method.

Expeller pressing is another method that is used to extract oils. In this process, the raw material is also crushed and pressed. Still, the expeller press differs from the cold press because it uses pressure generated by an expeller instead of gravity to push the raw material into the pressing equipment.

So, expeller pressing is basically a mechanical extraction process that uses pressure to extract oils from seeds and nuts.

During expeller pressing, the seeds or nuts are crushed, but not to the point of breaking open the cellular structure. After crushing, the material is pressed to extract the oil.

The expeller pressing process leaves behind much of the cellular structure, including many enzymes, which are beneficial in skincare.

The other method is mechanical pressing, which is also called pressing with no heat or expeller pressing.

The seeds or nuts are crushed in this process, but the cellular structure is broken open, releasing enzymes. Some producers prefer mechanical pressing because it’s faster than expeller pressing, but the downside is that you get fewer beneficial enzymes.

Another commonly used method is solvent extraction for essential and fragrant oils.

During this process, the desired oil is dissolved in a solvent. After the desired solvent has been filtered out, the oil is left in the container. The solvent is often recycled, and the oil is typically sold as “organic”.

Solvent extraction is the preferred method for obtaining organic oils. At this point, the oil must be refined to remove any potential pesticides or contaminants.

Solvent extraction is often used for non-organic oils as well. Some non-organic oils are not certified organic but are obtained from crops grown without pesticides.

Pressing with heat is yet another method of extracting oils. However, it’s usually used for vegetable oil extraction.

In this process, the raw material is also crushed and put into the pressing equipment, which is preheated to a specific temperature.

Industrial Seed Oil Extraction Machine – Pressing Oil from Seeds On Commercial Scale

This piece of equipment is used to extract oil not only from seeds but also nuts and other food sources.

Oil extraction machines are standard in large-scale manufacturing facilities where a large quantity of oil is produced. They are also used in the production of biofuels and other fuels.

The basic process for operating an oil extraction machine is similar to that of other extractors. The first step is to load the device with the material that will be used as the feedstock for extracting the oil.

Then, the machine simply uses one of these processes: cold pressing, expeller pressing, mechanical pressing, or solvent extraction.

If, in addition to seeds, you want to extract oils from your favorite fruits and veggies, then even a manual juicer can be an excellent option for you. 

Manual juicers are easy to use, inexpensive, and portable. However, there might be better options if you want to extract large quantities of oil.

The Seed Oil Press: Different Types Of Equipment

Mechanical extraction of oil is the process of extracting oil from seeds. It is done by carefully aligning the seed pod with a horizontal axis, then pressing its contents into the desired shape.

It can be done manually or with a machine. The process is called “mechanical extraction” because it involves moving the seed pod in such a way as to extract oil from its reproductive part.

The most common type of mechanical extraction equipment used for this purpose is a centrifuge, also known as a “mechanical mill”, which extracts oil from seeds using centrifugal force and force generated by rotating them. 

Other types of equipment include rotary pumps and cyclones, which can be used to extract oil through centrifugal force alone or combined with other means of extraction.

Final Words

Pressing oil from seeds can become an initiative that seeks to share knowledge about sustainability and oil extraction techniques.

The central concept behind this is to bring awareness to how essential oils can be used sustainably to create eco-friendly products.

There are many initiatives, events, businesses, and exhibitions around the world where you can meet and learn from people sharing their knowledge on pressing oil from seeds and sustainable living in general.

With a simple oil press, you can extract seeds for oils, herbs for essential oils, and create natural tinctures. The seed oil press is an excellent example of how innovation can be used to create a more sustainable lifestyle.
