You can also customize a distillation column to extract plant pigments, such as capsanthin.The four extraction kettles work in rotation in two batches. The excess CO2 in the extraction kettle can be transferred to another set of kettles. A CO2 recovery system is also equipped to help recover CO2 after each batch of extraction.
