Ethanol (Cold Ethanol Extraction)

liquid dropper

Positive displacement gear pumps are ideal for cold ethanol extraction due to their precise and efficient handling of viscous fluids at low temperatures. In the cold ethanol extraction process, maintaining the integrity and quality of the extract is critical, and these pumps excel in ensuring a consistent flow without causing excessive shear that could damage sensitive botanical compounds. Additionally, their robust design allows them to handle the challenging conditions associated with low-temperature operations, such as increased fluid viscosity. The pumps' ability to deliver a steady flow rate ensures optimal extraction efficiency, resulting in higher yields of purified extracts. Furthermore, the durability and reliability of positive displacement gear pumps minimize downtime and maintenance needs, making them a cost-effective choice for industrial-scale extraction processes.

Viscosity Through Thick and Thin
Viscosity is a measure of a liquid’s resistance to flow. And you don’t need to work in a laboratory to observe this. Anyone who’s spent any time in the kitchen has observed a variety of liquids with a wide variety of viscosities.

Current and Flow: An electrical engineer’s guide to the concepts of fluid systems
Unlike most of my colleagues I didn’t start out with a mechanical background.  While they were studying kinetics and machine design, I was studying digital electronics and industrial power.  When I started my career in the world of pumps, I had to learn a whole new set of concepts.  What was surprising was that while the terminology may be a bit different, the concepts are very similar.  Think of the following as a “Rosetta Stone” for translating the common terms and concepts of fluid systems to your more familiar terms and concepts of electrical systems.
