Liquid CO2 Pump with One Moving Part

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).

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

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

Date: 1/20/2019

Ethanol Extraction

With the huge influx of hemp flower and demand for hemp derived full spectrum oil and CBD, 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 CBD’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 CBD’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 CBD’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.
