What Makes a Good Extraction Machine

It is a scenario that some extraction machine sellers leverage by making unfounded claims, relying on misinformation, and employing questionable high-pressure tactics to secure sales. But as the old maxim dictates: Knowledge is power. So here's a quick rundown of the essential capabilities any high-quality supercritical CO₂ extraction machine must have and why these capabilities are so critical.



Supercritical CO₂ extraction enables skilled operators to develop innovative methodologies which maximize extraction efficiency, boost throughput and expand product options. But machines lacking the temperature and pressure ranges or the system stability needed to leverage the unique qualities of CO₂ miss an opportunity to deliver operators competitive advantages. A high-quality, instrumentation-grade CBD oil extraction machine will provide features like density feedback and control, inline fractionation, and software scripting and sequencing that enhance productivity and deliver robust R&D capacity that is key for new product development. The best machines even bring major downstream refinement processes onboard during extraction to exponentially increase production efficiency.



A quality CO₂ herb extraction machine will monitor and manage ongoing conditions throughout a run to sense conditions and make second-by-second adjustments necessary to ensure a quality outcome. When conditions fluctuate, or a human must babysit the extraction, accuracy, and consistency of performance diminish. Ultimately business profit margins suffer. Extraction machines that do not provide this precision and stability when running a batch — and many of the leading brands do not — make it impossible to understand exactly what's happening during extraction. The lack of precision eliminates the ability to repeat successful extractions, avoid failed extractions, and prevent compounds' loss. There is virtually no way to create effective standard operating procedures or properly plan the business.




Falling Film Evaporator
 Principle

The falling film evaporator has two main configurations, which includes the horizontal and the vertical tube,The horizontal tube is the most common design used in the desalination industry.




The draw backs of Falling Film Evaporator, including single effect falling film evaporator and multiple effects falling film evaporator.


The falling film may collapse during its down pass and result in partial wetting of the surface. This result in dry patches or areas covered with very small amount of liquid. As a result,complete evaporation of the liquid, which would leave salt scaling on the tube surface. Also, formation of dry patches would result in increase in the surface temperature of the tube. This would result in increase of the thermal stresses as a result increase in the tube expansion in the hot spots. Ultimately, the tube operation life is reduced because of bucking, scaling, and increase in corrosion rates.
