Solvent recovery refers to the process of recovering and recycling of solvents that were used in the manufacturing of cannabis concentrates. Because chemical solvents are so expensive for use in the cannabis industry, it makes solvent recovery an ideal method in order to cut down on costs. Solvents that are recovered from cannabis are ethanol, butane, hexane, propane, and isopropyl alcohol.
Once the solvents are recovered, they are placed into distillery tanks that heat and separate the solvents when they reach a boiling level and then turn into vapor. Once the vapor is collected and funneled into a cooled condenser, the solvents convert into a pure liquid and can then be used again. Resuing solvents has become a cost-effective and eco-friendly method that is widely used in the medical cannabis and cannabisextraction industry.
In an effort to lower production costs, hyperbaric chambers and ultrasonic distillation are becoming more and more common. The whole concept of solvent recovery is not new in the cannabisextraction industry. It has been around for many years, but the machinery that is used to recover those solvents has come a long way. The new methods now it is possible to recover up to 98% of the solvent from the extract. One of the biggest issues of solvent recovery is the amount of time that it takes.
The recovery of solvents requires just the right amount of heat and cooling to make the recovery effective and efficient. Some solvent recovery machines can recover up to 400 gallons of solvent per day, while others can recycle at a rate of 10 gallons per hour and come with a performance-based money-back guarantee.
Use of Term
I’m glad that solvent recovery has come such a long way in the cannabis industry. I won’t have to worry about toxins as much when dabbing my shatter.
