How to extract cannabis (CBD) oil from cannabis by short-path distillation?

Why do medicine extract cannabis (CBD) oil?

The international market for cannabis cultivation and production is currently estimated at $8 billion, and the liberalization of cannabis in other countries will result in a compound annual growth rate of 60%. By 2021, the international market for cannabis is expected to reach $31.4 billion. By 2027, global legal cannabis spending is expected to reach $57 billion. The adult (entertainment) market will spend 67% of the expenditure; medical cannabis will account for the remaining 33%. This shows that the use of cannabis oil (CBD) is very extensive.

Is it legal to produce CBD oil?

The sale of CBDs extracted from cannabis plants is fully legal in 32 countries in Europe.

The sale of CBD derived from cannabis is now fully legal in all states of the United States.

Canada As of October 17, 2018, it is expected that CBD sales in the supplement market will be legal.

Since cannabinol (CBD) oil has such a broad market prospect, then let's look at how to extract CBD oil using short-path distillation technology.

The first thing to understand is short-distance distillation technology? How does it work?

Short-path distillation is a very simple distillation technique involving the distillate traveling a short distance, usually only a few centimeters. This distillation technique is usually carried out under reduced pressure because it lowers the boiling point of the liquid.

Due to its low boiling point, it is a very effective method for compounds that are unstable at high temperatures. To complete such an experiment, only a few paths are required, so this is called short-path distillation.

Why use short distillation?

Short-path distillation is a high-precision evaporation instrument. It is integrally processed and formed, and it is not connected in the middle. The surface of the instrument has high surface finish and is not easy to stick. Moreover, it is also a short-path glassware that reduces the potential loss of material adhering to the inner surface of the device.

What role does short-path distillation play in extracting cannabis?

Hemp wax is dissolved at high temperatures, and hundreds of cannabis compounds can be extracted separately during the distillation because each compound has a different boiling point.

Why is temperature a crucial step in short-path distillation?

The key aspect of distillation in extraction and purification is temperature. Other chemical and physical variables are beneficial to improve the efficiency of the material reaction. But temperature is critical to achieving high yields. Vacuum is typically used to enhance the process by distillation at lower temperatures, thereby reducing the likelihood of changing the chemical composition of the distillate.

5. The evaporation cylinder is integrally formed without intermediate flange connection.

6. The surface of the cylinder has a high surface finish and is not easy to stick.

7. Unique liquid distributor and splash-proof device design to ensure product quality

What should you pay attention to when using short-distance distillation?

1. No load is not suitable for high speed operation;

2. Keep the speed regulation and the motor dry, because the life of the electrical box has a great influence on the surrounding humidity and temperature;

3. The ground wire must be well grounded, and the high temperature bath must be connected to the open switch;

4. There may still be electric shock within 5 minutes after the power is turned off, due to the discharge of the inverter or capacitor;

5. Please avoid damage to the glass caused by hard objects such as watches and rings when operating the instrument;

6. When the glass reactor needs heating, it should be gradually heated. Especially when heating at high temperature, it is generally recommended to use heat-conducting oil with little damage to the human body.

7. Check if the cooling water inlet and outlet valves are normally open and the pressure is within the normal range.

8. Check whether the inlet and outlet valves of the cooling water of each component are in the open state.

9. The equipment is heated by hot oil. The surface temperature of the external heating body is high. Do not touch it with your hands to avoid burns.

10. Check if the ethanol in the cryostat is sufficient.

11. Pay attention to whether the liquid nitrogen in the liquid nitrogen tank is sufficient.

12. Check if the connection between the cold well and the equipment is closed.

Short-path distillation has a small footprint, high-precision equipment and fair price. With such excellent equipment, it can extract CBD oil, and don't hurry to join the future market trend to gain more benefits!
