Starting a Hemp Extraction Business

With the incessant demand for consumer grade hemp rich products, along with isolate for product infusion, there is a bottleneck between harvest and concentrate extraction. This is because most farmers don’t have funding or capabilities to perform extraction. Third party extractors, termed toll processors, often demand a 50 percent toll for their services. Unfortunately, there aren’t many processors available and many are unreliable.

Of the extraction systems available on the market, they are high-priced, legacy-based systems that perform inefficiently, and effectively cause a bottleneck in processing.

Infinity Supercritical recognized these inherency’s in 2015, and established a line of technologically advanced extraction systems.

Why Now ?

Timing: The market has a high demand for CB D rich hemp products.

Opportunity for this market exists as processors scramble to meet demand, with legacy extraction systems. Unfortunately, ethanol extraction falls short with a inferior product that doesn’t have good terpene retention. Starting a Hemp Extraction Business (pdf)

Using Supercritical CO2 for Vapor Deposition of Sulfur on Carbon Nanofiber

Lithium Sulfur Battery Research using Vapor Deposition of Sulfur on Carbon Nanofiber: One interesting application may be for the research and production of lithium sulfur batteries. Using CO2 may be one possible route to commercialization of production. ( The team found that during the process of depositing sulfur on the carbon nanofiber surface, changing it from a gas to a solid, it crystallized in an unexpected way, forming a slight variation of the element, called monoclinic gamma-phase sulfur - link below.)

The modular construction of the system allow easy integration for new technology developments, and multi-role add-ons. The heart of the system is the phase change liquid pumping techniques, flow bar, and tribo effect electrostatic precipitation collection system. Many of these deployed technologies were developed by Infinity since 2015 making this system the most advanced in the industry. More than 100 of these commercial systems have been built and out around the world.

Pro Tips from Brook (updated on April 14, 2021):

Brook says that pump cooling is not required if the chiller is run closer to 40F, and the liquid CO2 reservoir is at a higher pressure (near 700 psi). Also said that matching the Collection Vessel (CC) closer to reservoir pressure resulted in beautiful quality honey looking oil extract. Brook runs for 2-3 hours and says running longer than that does not extract any appreciable amount of extract (i.e. waste of time for hemp).

The Infinity Supercritical CO2 hemp extractor can make craft extractions for your organic hemp flower. These range from making infused hemp cigarettes, hemp cigars ($20/each retail), tinctures, D8, and skin creams. We have a separate skin cream maker system which uses touch-free induction mixing for high value skin cream products (not limited to hemp, but can use any infused oil or botanicals).

Infinity Supercritical Review: Ethanol Extraction. The Good. The Bad. The Ugly.

Ethanol Extraction

With the huge influx of hemp flower and demand for hemp derived full spectrum oil and CB D, processors have turned to huge batch fed extraction methods.

Ethanol extraction is a low initial cost entry method to get a fast botanical extract. For the processor, it’s a quick way to turn cash flow.

For the consumer, they are unwittingly purchasing a product that is cheap to produce, but lacks the robust components when using CO2, or water extraction. Think of product shorting.

The long term results of ethanol processing are higher consumable costs, a highly flammable process requiring fire code compliance (Class 1 Div 2 D), and poor quality product. On the consumer side, the product shorting may not actually address why the consumer purchased the product in the first place (i.e. reducing inflammation from valuable terpenes and CB’s).

Fast Extraction: Large quantities of hemp need to be extracted at harvest time, and ethanol is one extraction method for bulk processing fast.

Low Capital Cost: Large batch fed assemblies are inexpensive to acquire.

Big Batch Quantity: .5 to .6 gallons of ethanol per pound botanical input. Can scale up to almost any size tank or batch.

Super Chill Extraction and Winterization: If you chill with CO2 or nitrogen down below -70 F, you can optimize extraction and winterization simultaneously.

Poor Overall Efficiency: Unless you use good quality (expensive) ethanol, poor overall extraction efficiency.

Terpenes: Poor terpene retention.

Appearance and Bitter Taste: Unless high quality solvent, expect green tints and bitter taste from chlorophyll.

Lack of Active Hemp Components: Depending on process, you may lose terpenes and CB’s.

Ethanol Recovery: A slow process to recover some of the consumable.

Lipids (Waxes): Ethanol pulls out long chain fatty acids very efficiently.

TIME: Carbon Filtering. Many processors use carbon filters to remove the green tint and bitter taste, which also removes the CB’s.

Poor Quality Ethanol: Expensive ethanol has low water content (good). Cheap ethanol (80-90 proof for example) has water content, which further reduces the quality of the extract (i.e. more green, bitter tasting chlorophyll, and poor extraction efficiency (bad).

Ethanol Storage Compliance vs. Expensive Rotary Evaporators: There are some huge compliance issues for storage. A potential solution is a large, but expensive, rotary evaporator to increase ethanol recovery.

Frequently Asked Questions

Why not go fully automated ?

CO2 extraction is already a legacy extraction method. In 2015 we surveyed industry extraction professionals and they wanted a semi-automated machine. We also surveyed Apeks Supercritical customers, and found their dissatisfaction with automation when the power when out (the CO2 was automatically vented, providing huge loss of CO2, which happens more regularly than you’d think), and software update issues. Apparently there were a number of lawsuits initiated because of unhappy customers. So we decided to apply our pressure vessel knowledge from our renewable energy systems (organic rankine cycle) to this industry. We made a system that was semi-automated. The only issues we have are with the Cat310 pump (as with every other extractor manufacturer who has problems with CO2 pumps).

What are the issues ? CO2 is high pressure. Sealing high pressure is difficult and expensive. Pumping a CO2 gas can be done with a diaphragm pump, which requires an external (loud and another maintenance item) air compressor (Apeks), or a liquid CO2 pump using pistons (most common and effective for liquid pumping). Other pumps exist, but cannot tolerate the pressure, unless you go exotic (i.e. expensive).

Why not just invent a new reliable pump ? We did. It was a liquid CO2 cavitation pump (see photo). One moving part. Magnetic seals. No pistons. No maintenance. Nobody had an interest in buying it.

What is the market ?

Below $10,000: Everyone can afford to buy at this price, but the extraction amount is low, customer service support high, and most at this level are in the hobby-want-to-be-commercial extractor, with very high expectations of profit. This is the group with the lowest amount of professional business prowess, and least educated to make a profit. Turnover, support, and refunds are high in this group. The general customer type is angry, and provide lots of threats (i.e. lawsuits, extortion, harm, fake social media posts, etc.).

$20,000-$50,000: Niche market and most active for purchases and businesses that want to make money and more professional.

Above $50,000: More professional clients, but harder to sell product.

Above $300,000: Most desired, but least available.

What has the Pandemic done to sales ? Sales have tanked. Nobody is spending money in this industry for equipment. The hemp market has seen raw hemp flower bottom out, since everyone wanted to grow this new novel crop.

What is the best technology ? Water extraction or oil-oil extraction. Both of these methods do not require high pressure, expensive fittings, or a CO2 pump (which is the heart of any CO2 system, and the most problematic). Either system can be push-button (for the operator factor).
