Super Critical Fluid Extraction: Its Wide Range Of Applications

Among the different extraction techniques used, supercritical fluid extraction (SFE) is one of the oldest and the most used separation technique. The use of supercritical fluids in the extraction of volatile components has increased during the last two decades because of its higher efficiency compared to other extraction methods.

Carbon dioxide (CO2) is the most widely used supercritical fluid. This is because CO2 is cheap, chemically inert, non-toxic, non-flammable and readily available at high purities and at low costs. Besides, the critical point of CO2 is easily accessible (critical temperature 31°C and critical pressure 74 bar) allowing the fluid to be used at mild conditions of temperatures (40-60°C) without leaving harmful organic residues.

With advances in process, equipment and product design and realization of the potentially profitable opportunities in the production of high added value products, industries are becoming more and more interested in supercritical fluid technology. It has found applications in many industrial sectors including food, cosmetics, pharmaceutics, materials, chemistry, energy and waste treatment.

Here are a few innovative applications of supercritical fluid extraction across different industries:

  1. Food & Beverage Industry
    One of the methods to improve the flavor of a beer is to enhance the intensity of the hops. Supercritical CO2 hop-oil extraction enables to obtain hop oil extracts with high concentrations and better quality.
    The association of high blood cholesterol levels with heart diseases is the motivating factor in recent works on the reduction of cholesterol levels in consumed meals that include meats, dairy products and eggs using supercritical fluids.
  2. Pharmaceutical Industry
    Among the varied extracts obtained from plants; antioxidants, phytosterols, or even the carotenes, which are used in the pharmaceutical sector, can be easily extracted using supercritical CO2.
    Supercritical fluids are utilized for the production of fine powders, in particular for the formulation of active principles. Pierre Fabre Laboratories (France) have developed the production of fine powders by supercritical CO2 and they were awarded the Pierre Potier 2009 “Innovation in chemistry for sustainable development” for its Formulplex process. This process uses supercritical fluids to increase the bioavailability of active principles.
  3. Medical Cannabis Industry
    Supercritical CO2 extraction of cannabis oil is gaining momentum in the USA as the process gives concentrate makers the ability isolate, capture and scientifically understand the medical effects of more elusive cannabinoids besides THC and CBD. 
  4. Wood Industry
    Superwood (Denmark) has industrialized the impregnation of wood with fungicides dissolved in supercritical CO2 ensuring a lack of mold, avoiding long baths and saving substantial amounts of fungicides.
  5. Textile Industry
    Conventional textile dying methods pose ecological and economical challenges. This issue can be tackled by using supercritical CO2 as an alternative solvent. FeyeCon (Holland), have been successful in the field of supercritical CO2 dying (DyeCoo process) which has been widely acknowledged and grown steadily since its inception.
  6. Energy production
    Extremely promising developments in the areas of liquefaction and gasification of biomass from agricultural wastes in subcritical and supercritical water has opened up the access to unique and sustainable energy sources.

At Cybernetik Technologies, we have developed completely customizable, state of the art and cost effective SFE systems that match international standards and help businesses in reducing batch times compared to traditional solvent based extraction processes, lower operating costs and achieving higher product purity.

Extract Essential Oil with no residual solvents and hazards using Advanced Supercritical CO2 Extraction

Extract Essential Oil with no residual solvents and hazards using Advanced Supercritical CO2 Extraction

The worldwide production and consumption of essential oils and perfumes are increasing at rapid speed. The traditional technologies for extraction of essential oil processing are of great significance, but one cannot deny the fact that they do have significant drawbacks compared to the advanced extraction technique like CO2 Supercritical Extraction. Why are traditional methods of extraction not safe? The traditional methods of essential oil extraction are hydro-distillation or solvent extraction. The concern using the traditional methods is the losses of some volatile compounds, low extraction efficiency, degradation of unsaturated compounds through thermal or hydrolytic effects and toxic solvent residue in the extract. Disadvantages of Water and Steam Distillation Due to the low pressure of rising steam, oils of high-boiling range require a higher quantity of steam for vaporization -hence longer hours of distillation. The plant material becomes wet, which slows down distillation as the steam has to vaporize the water to allow it to condense further up the still. Oxygenated components such as phenols tend to dissolve in the still water, so their complete removal by distillation is not possible. As water distillation tends to be a small operation (operated by one or two persons), it takes a long time to accumulate much oil, so good quality oil is often mixed with lousy quality oil. The distillation process is treated as art by local distillers, who rarely try to optimize both oil yield and quality. Water distillation is a slower process than either water and steam distillation or direct steam distillation. What is the alternative solution to overcome solvent residue and toxic solvents? The conventional extraction process has limitations of solvent toxicity, presence of residual solvents in the final extract and even loss of heat-sensitive oils. The rapidly emerging Supercritical fluid extraction technology is attracting more global markets and more […]

Why you should be going for Automatic Bagging?

Why you should be going for Automatic Bagging?

Auto bagging systems are now widely used in almost every packaging line. The packaging has become a lot simpler and safer thanks to the automatic bagging systems. Automatic bagging is basically the weighing of material, accurate product feeding, sealing, printing and safer transport of the product bags. By using an auto bagging system into your packaging operations, you will immediately start to experience benefits such as increased production, increased consistency, reduced workstations, reduced labor costs, greater accuracy, and product safety. Automatic bagging systems can be installed in a variety of production environments and are used for packaging a wide range of different products, including general distribution, cosmetics, food and beverage, pharmaceuticals and more. Speed The speed of manual operations is always limited and it takes much time to complete the packaging process. Automatic packaging machines take very less time to compare to manual work. It automatically fills and seals the product inside the plastic bag. An automatic machine works inline or rotary system and fill multiple packaging bag per minute. Reduce labor cost As you read above how the speed matters, an automatic bagging machine increases the speed of operations. More speed simply means more work. This machine helps to reduce your labor cost. Let’s say you need ten people for the packaging of multiple plastic bags. On the same time, a machine does this same work. That ten people take too much time for packaging and a machine done this within minutes. It means you need equipment that runs faster. It ultimately reduces the total cost of operation. Product safety Safety always has top priority in every industry. If the product is not packed properly, maybe it cannot be the sale and it will hamper the product identity and brand value. This can happen with your products if you get manual operations for packaging. […]
