Depending on how you finish your extraction and how long you recover, you can control how much solvent you recover. Under normal running conditions, the BHOgart loses less than 300 ml each time from the leftover butane in the hoses. The bigger the extractor the more loss is inherent to the design. The main places where solvent is released is in the material/material columns the more of them you have the more solvent you end up loosing in the system. Another spot where hydrocarbons are released is in the product Honeypots, or the extract itself. Through using best practices in solvent recovery the amount of solvent released can be reduced significantly.
Typically a Solvent extractor system will recover 95% of the solvent used during extraction.
on average around 0.5lbs per continues extraction, or 1-2lbs per full batch cycle
It is important to first understand that the unit moves solvent using differential pressure. Solvent evacuates from the cans which are at a higher pressure (30 – 40 PSI) into the extractor which is at a low pressure (-29″ Hg). As the can empties, the pressure in the extraction unit increases until it equalizes with the can. The first portion of solvent in the can unloads as a result of the vapor pressure of the gaseous butane pushing out most of the liquid butane. The can-tapper needs to be tapped about an inch up from the bottom of the can so that only liquid solvent comes out of it. The remaining solvent in the can needs to be removed with a temperature exchange, such as using ice water to chill both the recovery tank and the collection chamber. The coldness will cause a pressure differential, condensing the solvent back into a liquid.
Yes. You can load solvent straight into any BHOgart system from an LP tank. If you need special connection pieces, these can be provided upon request at the time of purchase. Let us know if you have any questions about getting your solvent tank connected to your BHOgart.
No, not at this time. You cannot run CO2 in any of the current BHOgart extractors for the simple reason that CO2 requires much greater pressures than butane/propane. The BHOgart is not designed for CO2 operating conditions which can be in excess of 200 Bar or about 3,000 PSI!
Yes. All Bhogart extractors are designed to run with Propane and Butane. Bhogart extractors are all multi-solvent compatible. Our customers have had great success running our systems using only propane, as well as using a mixture of propane and butane.
Propane evaporates at an extremely low temperature of -40F which, when combined with its higher vapor pressure, makes for a quick and cold extraction.
Interestingly enough, a mixture of propane and butane will not distill out from each other at their respective boiling points – instead the solvents will bond with each other and form a unique boiling point depending on their ratios. Despite this bond, the propane will still boil off faster than the butane. To better understand vapor pressure as it pertains to gas combinations, reference the following link: [Click here]
Always remember to source the most clean and pure solvent you can find for your extractions.
Yes. All BHOgart extraction kits come with a can-tapper which allows the use of almost any brand of canned butane or propane. We recommend loading the cans of solvent while the material tube is empty. This will allow you to distill the solvent by itself and remove toxic impurities like mystery oil. The cleaner your solvent is, the cleaner your extract will be.
If your BHOgart or any of your components are brand new, it is necessary to run and recover the solvent a few times through the system in order to ensure the removal of any manufacturing oils or contaminants.
