Hemp is an agriculturally produced crop that has existed for thousands of years, containing a large number of compounds that possess medicinal properties. Cannabis has played an ever greater role in medical science in recent memory, so there has been an ever-increasing demand for methods to extract and isolate bioactive compounds from marijuana plants effectively.

Cannabis plant product applications
Cannabis plants of the genus have a long history, mainly thanks to the sexually active compound known as tetrahydrocannabinol (THC), which has been used in the medical industry, specifically for pain management. However, scientists are recently getting curious about the other cannabinoids and are actively considering and seeing stunning results for their pharmacological impact. Several of the active ingredients are promising already in treating a range of chronic or acute health conditions. Specifically, Cannabidiol (CBD), a non-psychoactive agent, has an incredibly broad range of effects with extremely good tolerance. In addition, the carbohydrates, fat, and wax in cannabis are being increasingly used in cosmetics. This is why the consumer search for extract will only increase in the future – all the more so as more countries are now legalizing cannabis for medicinal use.
The standard principles of Canadian cannabis extraction production
Cannabis extracts Canada are produced by removing the cannabinoids and other constituents from the flower and leaf of certified Cannabis plants, mainly using various different thinners and extracting methods. The goal is the extraction of all constituents as completely and, most of all, economically as much as possible. Irrespective of whatever method of Extraction is employed, at the end of the procedure, the Solvent must specifically be recovered from an extract without any residues.
The solvents used are mostly Carbon Dioxide and ethanol but also liquefied lower molecular hydrocarbons such as Butane or propane can be applied. It is therefore very essential in cannabis extractions to maintain specific, in places varying temperature and Pressure ranges. According to the solvent unit state at standard extraction requirements, the extraction process requires liquefaction by either cooling and/or pressurization or vaporization by warming at the end of this process.
An ingenious system for controlling the thermal conditions of the processing plant ensures not only high extraction recovery but also efficient solvent recycling.
An example of an extraction procedure using CO2
A nice example of the principles revealed is the so-called Supercritical Carbon Dioxide Fluid Extraction, frequently used in cannabis extract manufacturing. The supercritical CO2 is produced when pressure and temp values are above the tipping points (at more than 30.98°C and over 73.75 bar pressure). In this condition, CO2 is liquid in color and gas in density, due to which solubility is increased dramatically. Pressure drops in the process of mining, which makes the CO2 fade away and releases the soluble material.
Higher heat and pressures allow extracts with the full manifestation of the terpenes in CO2 formulations. Novel tools of our extraction system even permit fractionation and thereby allow the separation of specific constituents. Radioles in the vaporizer include a heater system to extract the CO2 out of the solvent extract. The associated refrigeration unit, through which gas is recirculated back to its liquid state, makes it easy to recycle the CO2.
The permanent and accurate thermal control of all components, as well as precise regulation of the cooling and heating power in relation to the variable conditions such as plant growth medium and production rate, form the basis for a fine-tuned and highly efficient system.
Sales of cannabis are growing and demand effective and profitable processes for processing and extrusion. Today there is a wide range of end product choices on the commercial scene, from various consistency raw extraction to crystalline or soluble pure agents. The broad spectrum of cooking processes indicates the scope of potential dosage varieties. Those processes require certain thermal management, as close as permitted by the requirements set for the process possible.
