Complete Guide to Hemp Extraction Yields
Understanding Extraction Efficiency
Extraction efficiency is the cornerstone of profitable hemp processing. The difference between a 70% and 90% extraction efficiency can mean hundreds of thousands of dollars in recovered value over a year of operation. This calculator helps processors understand their theoretical yields, optimize their processes, and make informed decisions about extraction methods and equipment investments.
Extraction yield is determined by multiple factors: the cannabinoid content of your starting material, the efficiency of your chosen extraction method, process parameters, and post-processing losses. Understanding these variables allows you to predict yields accurately, price products competitively, and identify opportunities for process improvement.
The extraction process concentrates cannabinoids from plant material into crude oil, which can then be refined into various end products. Each extraction method has unique characteristics affecting yield, quality, and operating costs. This guide will help you understand these trade-offs and optimize your extraction strategy.
Extraction Methods Detailed Analysis
CO2 Extraction (Supercritical & Subcritical)
CO2 extraction uses pressurized carbon dioxide as a solvent to extract cannabinoids and terpenes. By adjusting temperature and pressure, CO2 can be tuned to extract specific compounds selectively.
Supercritical CO2 (>1,070 PSI, >88°F)
- • Efficiency: 85-95% cannabinoid recovery
- • Typical parameters: 1,500-4,000 PSI, 95-120°F
- • Extraction time: 4-8 hours per batch
- • Pros: High yield, no residual solvents, selective extraction
- • Cons: High equipment cost ($150K-$500K+), slower than hydrocarbon
- • Best for: Large-scale operations, full-spectrum extracts
Subcritical CO2 (<1,070 PSI, <88°F)
- • Efficiency: 75-85% cannabinoid recovery
- • Typical parameters: 800-1,000 PSI, 35-55°F

Ethanol Extraction
Ethanol is a polar solvent that efficiently extracts cannabinoids but also pulls chlorophyll and other unwanted compounds. Temperature control is crucial for selectivity.
Cold Ethanol (-40°F to -80°F)
- • Efficiency: 80-90% cannabinoid recovery
- • Solvent ratio: 10:1 to 20:1 (solvent:biomass)

- • Best for: RSO, tinctures, when color isn't critical
Hydrocarbon Extraction (Butane/Propane)
Hydrocarbon extraction uses butane, propane, or blends as solvents. These non-polar solvents are highly selective for cannabinoids and terpenes while leaving behind undesirable compounds.
- • Efficiency: 90-98% cannabinoid recovery
- • Typical pressure: 30-100 PSI
- • Temperature: -40°F to 40°F depending on desired selectivity
- • Extraction time: 30-90 minutes

- • Pros: Solventless, preserves terpenes, premium product
- • Cons: Lower overall yield, water-intensive
- • Best for: Hash rosin, premium concentrates
Maximizing Extraction Yields
Pre-Processing Optimization
Proper preparation of biomass is crucial for optimal extraction efficiency:
- •Grinding/Milling: Achieve uniform particle size (0.5-2mm for most methods). Too fine increases extraction of unwanted compounds; too coarse reduces efficiency.
- •Moisture Control: Target 8-12% moisture. Too dry causes static and dust; too wet reduces solvent penetration and can cause emulsions.
- •Decarboxylation: For activated products, decarb before extraction at 240°F for 40-60 minutes to convert THCA to THC.
- •Storage: Store biomass in cool, dark conditions. Degradation can reduce yields by 1-2% per month.
Process Parameter Optimization
Temperature Control
Lower temperatures increase selectivity but reduce yield. Higher temperatures extract more but pull unwanted compounds. Find your optimal balance based on end product requirements.
Solvent-to-Feed Ratio
More solvent generally increases yield but also increases processing time and solvent recovery costs. Typical ratios: Ethanol 10:1, Hydrocarbon 4:1, CO2 continuous flow.
Contact Time
Longer contact increases yield but may extract unwanted compounds. Cold ethanol: 3-5 min, Warm ethanol: 20-30 min, Hydrocarbon: 30-90 min.
Multiple Passes
Second pass typically recovers 10-20% of first pass yield. Third pass 5-10%. Consider diminishing returns vs. processing costs.
Post-Processing Considerations
Post-extraction processing can significantly impact final yields:
- • Winterization: Removes 5-15% mass (fats/waxes) but improves quality
- • Filtration: Each filtration step loses 1-3% to filter media
- • Solvent Recovery: Incomplete recovery can lose 2-5% of extract
- • Decarboxylation: Post-extraction decarb loses 12.3% mass (CO2 release)
- • Distillation: First pass 60-80% recovery, second pass 80-90%
Economic Considerations and ROI
