Cold press oil machines are designed to extract oil from nuts or seeds using a simple yet effective process.
How does a cold press oil machine work? 4 Key Steps Explained
1. Pressing the Nuts or Seeds
A cold press oil machine uses a screw to press nuts or seeds through a barrel.
This creates friction and pressure on the ingredients.
As a result, the ingredients release their oil.
2. Separation of Pulp and Oil
The pulp from the nuts or seeds is separated from the oil.
The oil then drips into a container.
3. Winterization for CBD Oil
In the case of CBD oil distillation, an additional step called winterization is required.
Winterization involves mixing the CBD oil with 200 proof alcohol and placing it in a deep freeze overnight.
This process helps remove plant waxes from the oil.
The mixture is then filtered through a funnel and flask to further remove the waxes.
A vacuum pump is often used during this step.
4. Distillation Process
After winterization, the oil still contains alcohol, so it is heated in a rotary evaporator to remove the alcohol.
This process helps refine the oil from its crude state.
The resulting oil is winterized again to ensure all plant waxes are removed.
The first, subcritical extract, which retains terpenes, is added back into the oil to enhance its flavor and aroma.
In short path distillation, the winterized and decarboxylated CBD oil is introduced to a round bottom flask, which is then heated by a heating mantle.
The heated oil vaporizes, and the volatile components are collected on a chilled condenser.
This process separates different components of the oil based on their boiling points.
The separated components are then collected as the desired distilled CBD oil product.
