bottle filling machines

Recommended Posts

Hello! I am writing to inform everyone in the Distilling Industry about the NEW OWNERSHIP of Vigneron / XpressFill bottle filling machines. Many of you have older Vigneron fillers collecting dust (or worse) in your businesses. We would like you to know we have completely redesigned the machines, and offer upgrades to bring your older machines up to date with the new digital controls and completely new engineering. The new machines, now named XpressFill, have supreme accuracy (within 1.5 ml, calibrated at the factory) and amazing user-friendliness. Please write or call us for more information. Here is a little background information:

Vigneron / XpressFill has NEW owners who have spent the past 2 years completely revamping the machine and the company. Randy Kingsbury is a Professional Mechanical Design Engineer with over 25 years experience, and Judes Kingsbury has 20 years of Restaurant, Winery and Customer Service / Management experience. Since the time of purchase, Randy completely redesigned the machine and the two put in place outstanding customer service. The company has upgraded numerous older Vigneron fillers to the current technology, have sold many brand new XpressFill bottle fillers to artisan producers, and now boast a myriad of happy customers around the world. The machine's new design is extremely user-friendly, comes with a digital timer and performs with outstanding precision - within 1.5 ml accuracy, calibrated at the factory. All XpressFill bottle filling machines come with a satisfaction-guaranteed warranty. You can view a demo of their new systems at XpressFill.com, and reach them directly at (805) 541 - 0100 or info@Xpressfill.Com, Judy@XpressFill.com, Randy@XpressFill.com <mailto:info@xpressfill.com>

Welcome Randy.

You may recall that you shared raw-data from fill accuracy tests between the new and old machines. I believe that I related the results to you over the phone, but here's a synopsis for others:

The Coefficient of Variation (CV) is the most commonly used statistic used to express fill accuracy. The CV is the Standard Deviation (SD) divided by the Mean. In other words, you fill lots of bottles, measure the results, and you will find that if the machine is supposed to be filling to 750mL, the results will be scattered (SD) around nearby value - the Mean (or average). The SD provides a penalty for larger scatter - twice the scatter produces a number four times larger. The CV makes sense because it relates the amount of scatter to the volume delivered. A 1mL variance is a big deal on a 50mL bottle, but not such a big deal on a 1750mL.

The older model had an overall mean (all spouts) of 744mL, and a SD of 3.75mL - for a CV of 0.5% - which would be considered just fine in some circles, such as drug delivery.

The newer model was a different animal. In this case, the accuracy of your measurements in providing the data may be causing more error in the outcome than the filling machine. With a measurement resolution of 1mL, it may not be possible to properly evaluate the machine if it's doing significantly better than your measurement resolution. For a machine of this performance, you need to be reporting measurements with resolution or 0.1mL or better. This is not possible with a graduated cylinder. I recommend that you revise your measurement protocol and purchase a high-resolution analytical balance and measure your volumes by weight conversion.

In the data I reviewed, the newer model had a Standard Deviation of less than .5ml in some tests, and this would mean a CV of about 0.06% for 750mL deliveries. That's significantly better than the older model.
