Hot FAQ

Q Is caffeine soluble in liquid co2?

A

Supercritical CO2 helps act as a solvent to give the coffee bean solvent-like properties to dissolve the caffeine and extract it out of the coffee bean. Because it has a lower viscosity than liquid CO2, allowing it to move through and around the coffee bean more efficiently without too much pressure.
Q Is co2 extraction organic?

A

CO2 Botanical Extracts are completely natural and exceptionally pure. These highly concentrated plant extracts are free of solvent residues and impurities such as heavy metals. All CO2 Extracts are oil soluble.
Q Why is co2 better than ethanol?

A

CO2 is highly tunable. With CO2 you can vary factors such as time, temperature, and pressure to create different products. Ethanol products need to go into more stages of refinement to be turned into various products such as distillate.
Q Does co2 extraction remove terpenes?

A

CO2 extraction is good for preserving terpenes because it is a cold separation process that can protect delicate plant compounds. Some methods may also use ethanol to help remove terpenes before fully extracting cannabis buds.
Q Is co2 extraction better?

A

CO2 extraction is also much better for the environment. CO2 gas is natural, so if it escapes into the air during extraction it won't do any harm. It can also be recycled, making this method much more sustainable. Since the solvent isn't toxic, people working with this extraction method don't face any health risks.

Supercritical CO2 Extraction Machine Working Principle and Characteristics

Supercritical fluid extraction is a new separation technology in modern chemical separation. Supercritical fluid refers to fluid in the thermodynamic state which above the critical point (PC, PT). The critical point is the state where distinct gas and liquid phases do not exist.

Supercritical fluid has its unique physical and chemical properties, it is almost as dense as liquid and as viscosity as gas. It can effuse through solids like a gas, and dissolve materials like a liquid. Many characteristics, like high diffusion coefficient, low viscosity and large dissolvability .etc, prompt good separation effect.

Supercritical extraction means that the solvent and extracted substances in the extraction kettle, under high pressure and appropriate temperature, the solvent diffuses into the kettle, and change the operating conditions to separate the dissolved substance.

Supercritical CO2 extraction device takes CO2 as the solvent, which has many characteristics:

1. Wide operating range and easy to adjust.

2. By controlling pressure and temperature, extract the required ingredients.

3. Low operating temperature, closed to room temperature, which is especially suitable for heat sensitive components. In the extraction process, the possibility of oxygenation and light reaction is excluded, and can maintain its natural flavor.

4. We can finish extraction to separation in one step, and there will be no residual components in the extracted material.

5. CO2 is non-toxic, non-odor, non-flammable, low-cost and recyclable.

6. Fast extraction speed.
