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.

Factory Acceptance Testing (FAT) - An Essential for Optimum Delivery

Delivering quality and exceeding the expectations of our clients is always a requisite at Cybernetik. Factory Acceptance Testing or FAT is one of the project milestones that helps us meet our goals and ensure smooth functionality of the system through its entire lifecycle. Systems that go through rigorous FAT enable our clients to achieve optimum productivity and be the frontrunners in their respective industry. What is FAT?Prior to the delivery and shipment of any automation system, we build the entire system at Cybernetik, just as it would have been built at the client’s place and perform a comprehensive scrutiny, also known as Factory Acceptance Testing or FAT.  This scrutiny includes checking the system for a number of factors like Functionality, SLA adherence, Legal & Compliance accuracy, P&ID and quality certifications. Going further, at Cybernetik we also prepare the system for Key Performance Indicators (KPIs) such as production rate (cycle time), process flow, user interface, workmanship and safety. When is FAT performed?  FAT is performed before we dispatch the system from Cybernetik. It helps us ensure quality and safety of the system. It also saves on time and cost. Issues can be identified and rectified while the system is still in our factory. This reduces the initial hassles while setting up the system at the client’s place and reduces the time to make it run smoothly and to its full capacity. In addition, it gives client a clear idea of the physical layout and if there is a need for alterations and reconfigurations, they can be implemented prior to the delivery. Who should be present during FAT?To ensure the success of FAT, we recommend the presence of personnel from client’s side on the shop floor. The personnel could be Project Managers, Operators, Plant Engineers and Maintenance Engineers. This helps everyone understand the environment where the system is being tested enabling better troubleshooting in case of breakdowns during run-time. Why is FAT important?FAT helps identify non-conformities in the system while the system is still at Cybernetik, so that problems can be addressed before installation of the system. This offers more flexibility to our technical experts for providing optimal solutions, without affecting the project timelines. FAT also eliminates ambiguity around the KPIs set for the equipment. Though Cybernetik incurs considerable costs simulating real-time shop environment for the system to be appropriately evaluated, this lowers the risk of breakdowns during shop time as well as the need for repetitive servicing. At Cybernetik, FAT is not billed to the client separately, as it is included in the scope of delivery established earlier. We clarify and lay down the requirements and measures that will compose a customised FAT, and these are carefully implemented to ensure the success of FAT. Just like before delivering any product, the manufacturer checks it for quality, FAT is performed before the shipment of automation equipment to ensure its quality standards and full functionality. It is also important for ensuring safety of equipment and personnel. After all, creating safer workplaces is one of the most important aspects of industrial automation.

Creating Safer Workplaces through Industrial Automation

Safer working environment for humans is one the biggest boons of automation. Everypassing day, innovative automation systems are being created all over the world to keephumans away from dangers. These dangers might pose an immediate risk to the life or bodyparts of humans or they might be in the form of tasks which put human health at risk if theycarry out these tasks over a long term. Here is how automation can help in eliminating thesedangers.Preventing loss of life or body partsIn automotive manufacturing, press shop is one of the most accident prone areas. There areinnumerable cases where operators have lost their fingers or even hand while working withthe press machine. In fact, in one of the unfortunate accidents, a maintenance operator losthis life while doing the routine maintenance of a press machine.Press machines require an extremely high level of eye-hand / foot coordination. Not tomention, the machines are absolutely unforgiving of mistakes. A single blink of an eye andthe operator can lose a precious part of his body. Press loaders and unloaders fromCybernetik can help manufacturers keep workers away from this accident prone area andmake the workplace safer for them.Eliminating cumbersome tasksCertain industrial tasks need to be done and need to be done at a specific speed to continuethe production line without being interrupted. This is also necessary to achieve economies ofscale in price-sensitive markets like automotive manufacturing or FMCG products like snackfood items.Such tasks and their speed requirements make them too cumbersome for humans. Imaginea shop floor worker lifting and moving a 100 kg bag several times a day. It not only puts theworker’s health and safety at risk, it also negatively affects the manufacturing line as humanswill inevitably work at reduced speed after some time. This creates a bottleneck in thesystem, which can be easily and efficiently avoided through automated systems like roboticpalletizing.Production of food items may not be an obviously risky or unsafe process. However, whenfood items are produced on the industrial scale, it can quickly transform into a cumbersometask. Take the example of a worker who is working in a factory that produces savoury friedsnacks and who has to deep fry the food items. He needs to work in the dangerous vicinityof an enormous quantity of boiling oil. Besides, the fire and heat also pose the risk ofdehydration.Apart from this, the highly repetitive task can quickly become a boring chore for humans.Bored humans may or may not follow the standard procedure while doing the task. This notonly puts humans in the close vicinity of a danger, it might also lead to the production ofsubstandard quality food items, which again becomes a health risk for consumers. Snackfood automation helps in avoiding these risks, making human resources available for moreskilled tasks.Keeping humans away from hazardous materials and environmentsIn industrial manufacturing, humans need to work with all kinds of materials. Some of themare not safe for humans and might put their health at risk. For example, there might behazardous chemicals, which need to be packed in bags. Exposing humans to thesechemicals might put their health at risk in the long term or sometimes even in the short term.Automatic bagging systems help in eliminating this risk.In certain cutting tasks, the dust produced during the process is harmful for humans. Itbecomes a health risk for them when it enters their eyes, mouth or nose. To prevent this,completely automated systems are designed, which are then covered with a canopy so thatthe dust does not get spread into the atmosphere.There are several such examples of automation systems that help prevent or reduce safetyrisks to humans in different industries. Cybernetik can work with you to design and createautomation systems to enhance safety in your industry. Get in touch with us to know more.

Six-Axis Robots: What are they? Their Benefits & Integration

Robotic manufacturers have designed and developed several different types of robots to fulfill the automation needs of various industries. The standard Six-Axis Robot is one of the most widely used among them. Axis: The Facilitator of Robot’s Movement A major factor in an industrial robot is the number of axes it has. Each axis allows a degree of flexibility and enables a robot to reach to the desired point. The six axis robot, can move in three dimensional space across x, y and z planes. Different types of robots are suitable for different industrial applications. Certain tasks like part picking, material handling, sorting, stacking and palletising can be accomplished with fewer axes. Robots with fewer axes provide more stability, are simple to operate and maintain and also reduce energy consumption and overall cost. Certain other tasks like assembly may require a robot with as many as 15 axes, where more flexibility is required. But these robots also tend to be more expensive. Six-Axis Robots Most of the industrial applications can be carried out with the help of the standard six-axis robots, also called articulated robots. These provide a good combination of power, stability, flexibility and value for investment. Here is how each axis allows flexibility to the robotic arm. Axis 1: Located at the base of the robot, it allows the robot to move in the range of 180 degrees from left to right. Axis 2: Facilitates the forward and backward movement of the robot’s lower arm. Axis 3: Allows the robot’s upper arm to move in upward and downward direction. Axis 4: Known as the wrist roll, this axis rotates robot’s upper arm and working together with axis 5 positions the end effector. Axis 5: Allows the robot’s wrist to move in upward and downward direction with pitch movement and move from side to side with yaw movement. Axis 6: This is the robot’s wrist and enables it to rotate freely in both left and right directions. Benefits  Optimum flexibility Easy programming Multiple mounting options Easy maintenance and repairing Adaptability  Integration Cybernetik offers complete integration of all types of six-axis robots from the well-known manufacturers like ABB, Kuka and Yaskawa. There are many different types of six-axis robots, both large and small. According to the specific requirements of the task, different factors need to be determined like size, speed and payload. Cybernetik offers end-to-end assistance in this regard from selecting the right robot to installation and after-sales support. Contact us to know more.
