There are as many ways to extract essential oils from a plant material as there are recipes to make bread from grain. Developing your Standard Operating Procedure (SOP) means defining three main considerations; 1. Capacity per hour, 2. End goal or use of extract, and 3. Variety, condition, and harvest method of biomass.
Capacity – The guide below is based on processing 500 lbs of dry biomass per hour. Therefore, this SOP might not apply directly to the SOP of a system that is processing 10-20 lbs per hour.
End Goal – We designed our system to produce isolate in the most energy efficient way, while maintaining end product quality. For example, if the end goal is non-winterized crude as a direct retail product ingredient, a different SOP is used.
Biomass Quality – Hemp strain, concentration of cannabinoids, harvest methods, drying methods, post harvest handling/shipping, age of biomass, etc., all play a role in developing how it’s extracted.
