A lot of variables go into the specific pressing of different seeds, but the main concept stays the same. First you dispense raw seeds into the seed hopper, then an expeller screw crushes the seeds. Next, the oils run through canals where the pulp gets separated from the oil.
As CBD oil’s lesser-known cousin, hemp seed oil provides its own unique set of health benefits and its own special manufacturing methods. Since its discussed less often, we thought we would take a closer look at hemp seed oil.
MAKING HEMP SEED OIL: THE TRADITIONAL METHOD
Seed quality is another important characteristic. Non-ripe seeds produce different quality oils and smells than ripe seeds. And obviously seeds that are moldy and improperly stored will produce low-quality oil. The actual operation of the seed press is important too, as the settings for the machine greatly affect the pressing method and pressing temperature. An operator must know how to manipulate the distance between the press head and the screw end, the speed of the press, the tip size and the type of screw needed for the seed. This is why having a well-experienced seed press machine operator is important for companies looking to produce quality hemp seed oil products.
Making hemp seed oil on a hand crank seed press is easy. First, set up the press on a flat, secure surface. Next, you’ll fill the attached oil lamp and light it for 10 minutes prior to operation. This warms up the crank and ensures the oil separates. Then, simply put seeds into the hopper and crank away!
While the traditional oil press method seems simplistic, it’s actually surprisingly complex. Many variables go into seed pressing that can make or break a batch of oil.

If you like using hemp oil at home, creating it yourself makes sense. Keep in mind, hemp seed oil refers to a carrier oil made from the seed, much like flaxseed oil or canola. It can be used as a moisturizer or in foods.  X Research source However, it’s difficult to make at home because you need a large press. Hemp CBD oil, on the other hand, is where you pick a carrier oil like olive oil or coconut oil and infuse it with hemp. CBD oil can technically be made from cannabis or hemp; hemp is the same plant, but it contains less than 0.3% THC, the compound in cannabis that gives you a high. To make hemp oil at home, you can either finely chop hemp buds to infuse the oil or use a CBD concentrate for a simple process.
