Making distilled spirits better with Persedo and Alicat instruments
Alicat instruments are used in a wide variety of applications. We’re found in vacuum coating applications, food processing and the creation of fiber optics cabling. Alicat instruments test components to verify they are space worthy, provide flow control precise enough for even paint deposition from automated painting machines and precise enough to control propulsion on spacecraft while having no unintended recoil or counter effect from the device. With multidirectional flow control, we can mimic filling a car tire to pressure under test situations or simulate breathing. Alicat devices are built for each customer and with each application in mind making Alicat devices well suited to many diverse industries.
But in distilling and the refining of alcoholic spirits?
Yes, Alicat instruments can even make your mixed drink better. A company called Persedo uses Alicat mass flow controllers in their process that improves the quality of distilled spirits using a combination of ultrasonic energy, vacuum and extractive food grade gases.
The quality of a whiskey, vodka, rum or tequila can be dramatically improved in a matter of minutes by removing components which cannot be removed by distillation alone and by changing others in situ. Persedo uses an Alicat mass flow controller to precisely control flow rates of food-grade gases flow into their distilled spirits processing system. By passing two gases through the Alicat instrument, they are able to selectively strip off-flavors and off-odors from distilled spirits. The system has been used to process as many as 1000 spirit test samples.
“No other device offered us the cost-effective, dynamic process control capability and precise control (better than 0.5% of total volume) of flow rates made possible by a mass flow controller from Alicat,” said Greg George, the senior chemist and technology lead. “Precise measurements of volume flow rate corrected for variations of temperature and input pressure from tank gases is key to the quality control in our process.”
Because Alicat devices can be controlled simply from the home screen or through various communication and industrial protocols, it is easy for Persedo and other customers to tie Alicat devices into the rest of the instrumentation and have them communicating through, for example, RS-232 to a computer without any additional modifications. Clear communication means speed and accuracy are increased. It is easy to make adjustments as needed, from flow rates to turndown ratios and even to the percentages of gases flowing into the system.
Challenge us with a new application or process. Alicat instruments are being used to improve outcomes in new and exciting ways on a regular basis. With a team of skilled Applications Engineers working with each customer every step of the way and a cohort of test, electrical and fluid dynamic engineers developing the next generation of our devices, Alicat devices are always evolving and moving science and technology forward.
