Natural fat-soluble bioactive compound extraction systems
Supercritical and subcritical extraction
Carbon dioxide extraction
Supercritical and/or subcritical extraction is a process used to obtain extracts and other substances using gases which are under super- or subcritical conditions. Supercritical gases have all the physical properties of gases, but they are incompressible and possess the same dissolving power as liquids.
The advantage of supercritical extraction is that pressure and temperature changes influence the dissolving power, which means the extraction process can be adapted to obtain specific substances from the collective matrix. This method is used in the production of bioactive compounds from herbs and other plants, where a high degree of extract purity is required, especially in the pharmaceutical and food industry. It is most known for its use in the production of hemp paste, as well as decaffeinated coffee and tea.
This method is considered environmentally friendly, as it doesn’t create any unwanted or harmful side products.
At Škrlj d.o.o. we always try to further develop and upgrade the supercritical extraction system and its equipment to better fit our customers' needs and facilitate its use. For this purpose we have developed the Škrlj MoSES system, which is used for the sub- and supercritical carbon dioxide extraction of natural and organic bioactive compounds.
- modular design
- entirely automatic system
- certified and tested in accordance with EU standards
The entire system is supported by a compact frame with an electrical cabinet, as well as a gas supply and pressure regulation system, while the extraction modules can be varied.
We offer laboratory systems with two or three collection vessels (1, 2 or 5 liters), which can operate in parallel or sequential mode. Additionally, we manufacture semi-industrial and industrial systems with two or three extraction vessels (10 or 25 liters). Customer requests are always taken into consideration and, if possible, implemented and developed into unique technological solutions.
More about CO2 extraction
Supercritical extraction throughout historyThe supercritical state of fluids was discovered by the French Baron Charles Cagniard de la Tour in 1822, although the true significance of his discovery and the possibilities it opens up became apparent only later ...
Smart Investment in Slovenian Supercritical Extraction SystemPharmaHemp, one of the world's leading companies in the field of research, development, processing, and laboratory testing of raw materials and industrial hemp products has taken a major step forward by acquiring a highly efficient CO2 extraction system that can be used to obtain plant extracts for the food, cosmetic, and pharmaceutical industries.
Fully automated extraction systemIn complex processes, such as extraction under supercritical conditions (high pressures and elevated temperatures), automation reduces numerous risks and ensures standardized system operation in accordance with occupational safety standards. Automation also ensures optimal system efficiency during operation and has a significant effect on the quality of the final product.
Green extractionThe extraction of nutrients and natural products has a long history - its origins can be traced all the way back to the ancient civilizations. At the time, the extracts were used for food, cosmetic and spiritual purposes, much like today. Today it is impossible to find a production process in the food, cosmetics, pharmaceutical, advanced materials, and chemical industries or the production of biofuels that does not include extraction processes.
Pressure equipment and the PEDThe Pressure Equipment Directive or PED (2014/68/EU) sets out the requirements that pressure equipment manufacturers must meet if they want to sell their products in Europe. It applies to the design, manufacture, and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure PS (the maximum pressure the components can handle based on the design) greater than 0.5 bar. Pressure equipment and assemblies may be made available on the market or put into service only if they satisfy the requirements of the Pressure Equipment Directive, i.e., if they are manufactured in accordance with the Directive, if they are properly installed and maintained and if they are used for their intended purposes.
CUBE2BREW // Slovenia
Mobile Container Brewery
Together with Dematech, our distributor for the South African region, we have designed and successfully carried out a mobile container brewery project. In November 2019, the Cube2Brew mobile brewery completed its first long journey as it travelled to Nürnberg, where it was part of, or better yet, the star of our stand at the BrauBeviale, a famous international beer brewing trade fair.
