Method to produce concentrated volatiles from cannabis

A method to produce concentrated volatiles from cannabis, the method includes:

• (a) providing a source of cannabis, the cannabis includes volatiles, the volatiles include terpenes, wax, and oil;
• (b) after step (a), extracting the volatiles from the cannabis with CO2 to form a CO2 and volatiles mixture according to a method including:
• (b1) separating the terpenes from the cannabis at a first temperature and a first pressure;
• and
• (b2) after step (b1), separating the oil and the wax from the cannabis at a second temperature and a second pressure, the second temperature is greater than the first temperature, the second pressure is greater than the first pressure, the CO2 and volatiles mixture includes CO2, oil, and wax;
• (c) after step (b), removing the CO2 from the CO2 and volatiles mixture to produce extracted volatiles, the extracted volatiles includes oil and wax;
• (d) after step (c), mixing the extracted volatiles with ethanol to produce an ethanol and volatiles mixture;
• (e) after step (d), cooling the ethanol and volatiles mixture to form a cooled ethanol and volatiles mixture;
• (f) after step (e), filtering the cooled ethanol and volatiles mixture to form a filtered ethanol and volatiles mixture;
• (g) after step (f), evaporating the ethanol from the filtered ethanol and volatiles mixture under vacuum conditions to produce concentrated volatiles and vaporized ethanol;
• (h) after step (g), condensing the vaporized ethanol to produce liquid ethanol and non-condensable gas, the non-condensable gas has a reduced amount of ethanol vapor relative to the vaporized ethanol;
• and
• (i) after step (h), introducing the non-condensable gas to a vacuum system.
