Ultrasonic processing in the cannabis manufacturing

Ultrasonic cleaning is the most common application of this technology. Ultrasound generates millions of tiny vacuum bubbles in the cleaning fluid, producing high pressure during their formation. This physical reaction allows optimal cleaning of various objects such as silverware in gastronomy, jewelery jewelry or laboratory glassware.


Did you know that ultrasonic technology is also applicable in the extraction and refining of cannabinoids? Swissbis Research is the first laboratory to use this technology throughout its production process. This publication details its use in a simple and understandable way.




Ultrasonic-assisted mechanical extraction


Mechanical extraction of trichomes. For millennia, the man practices the mechanical extraction that it is by pressure or by agitations. When we shake an apple tree, it is correct to say that the apples are extracted by mechanical action. It is the same at Swissbis Research but with trichomes, these glandular protuberances of cannabis that retain the active ingredients of the plant. Flowers arriving at the laboratory are inspected and analyzed thoroughly for compliance. Then they are placed in a cryogenic cell to reach temperatures around -80.C. This helps to remove excess moisture. Then the ultrasonic technology intervenes. The flowers are shaken at the top of a sieve and the trichomes are recovered after thousands of shakes produced by the ultrasonic device. Their purity is relatively high and allows their immediate use especially for acid cannabinoid formulations.

Ultrasonic-assisted solvent extraction


It is indeed for this type of extraction that ultrasound is the most effective. It is very common for a laboratory to use standard ethanol, hexane or heptane solvents to extract cannabinoids. But because of their polarity, some Solvents also extract other undesirable components of the plant. This is why many labs cool their solvent, which has cryogenic temperatures will have less tendency to extract chlorophyll for example. Swissbis Research uses an internal technology that accelerates the extraction of cannabinoids in the solvent, with ultrasound promoting molecular friction between the solvent and trichomes. This therefore reduces the residence time in the extraction chamber, the amount of solvent used while increasing the extraction quality.



Ultrasonic nano-dispersion


Nano-dispersion is an advanced homogenization process that significantly increases the bioavailability of an active ingredient. That is to say that it becomes better assimilable for the human body. Swissbis Research is also a pioneer in the use of this technology for the manufacture of cannabis extracts . Ultrasound, specifically the cavitation phenomenon allow the reduction of nanoscale particles. This is why nano-dispersed dyes are better assimilated by the human body. Do you hear of the talk of water-soluble solution? Cannabinoids have no solubility in water but thanks to the use of ultrasound it is possible to encapsulate them within the water itself. This is an excellent option for water-based products such as natural drinks.
