Making a Banana Milk in the Vitamix Pro 300 and Blendtec DesignerSeries side-by-side (with video)

Back when I bought my first Vitamix, a 5200, one of the very first things I made, and one of the reasons I bought it, was Banana Milk.  Basically, blend a frozen banana and milk.  Made correctly, it’s awesome.  Unfortunately, it will eventually (or quickly) break normal (weaker) blenders, and getting the entire banana blended so there are no chunks left takes time or a good blender.

Banana Milk is a pretty demanding test for any blender, so when I bought my 7500 back in 2012, I compared it to the 5200 by making a Banana Milk in both blenders simultaneously:  Making a Banana Milk in the Vitamix 7500 and Vitamix 5200 side-by-side (with video)

Not long after that video, unique circumstances lead me to get a Professional Series 300 and returning my 7500, though the two blenders are essentially identical.  That is the blender that I have been using regularly for a little over a year now.

Exactly one week ago I got a Blendtec Designer Series, and while I broke out my camera to document the physical differences (Physical Comparison: Vitamix Professional Series 300 vs. Blendtec Designer Series) between the two blenders, I was far more interested how their performance compares, and that’s what I set out to by making a Banana Milk in both the Pro 300 and Designer Series.

Last time, I subjected both blenders to an overly grueling test, as I did not include as much milk as I normally would, and did not use the tamper.  You can watch that video if you want to see how a Pro 300 or 7500 performs without a tamper, so I thought I would use a tamper this time to reflect how I normally make Banana Milks in the Vitamix.

While I documented the various run times of the pre-programmed cycles on the Blendtec, I hadn’t actually used them before this video, so I didn’t know exactly what to expect, but the Smoothie cycle seemed stronger and longer than the Milkshake, so that is what I decided I would use for the Blendtec.

As you’ll see in the video, in addition to preparing equal amount of milk and equal sized bananas that were frozen in my refrigerator over several hours, I took four kids cups from Moe’s and wrote B on the bottom of two and V on the bottom of the other two, the idea being that I would mix two glasses of the Banana Milk made by the Blendtec and two glasses made by the Vitamix and mix them all so that even I didn’t know which was which, and see if I could tell the difference between the two.  Watch the video to see how the actual mixing went:

The Blendtec pre-programmed blend was definitely not up to the task, and even on various manual settings, I could not find a good setting that effectively blended the banana.  As I noted in my physical comparison, the Blendtec has two large, dull blades, while the Vitamix sports four sharp blades.  It seems that the combination of the blades and blender container design make the Vitamix more effective at blending a large, thoroughly frozen banana with milk.  Another side effect of using the Blendtec that have noticed in my limited use is that the Blendtec seems to more effectively heat the mix it is blending than the Vitamix.  That could be great for soup, but it’s not great when I’m blending something frozen and the Blendtec already needs to significantly longer to blend.

So what were the results after the camera stopped rolling?

The Blendtec was warmer, still had large chunks of unblended banana, and lacked the whipped, rich, creamy consistency that makes Banana Milk such a treat.  The Vitamix wasn’t perfect, there was a very small chunk I missed, as I was trying to pour the Vitamix glasses a tad earlier than I normally would, in anticipation of the Blendtec being ready to pour at the end of it’s 40 second cycle (the Blendtec does count down it’s cycle in seconds on the LCD panel, which is a nice touch), but it turned out the Blendtec was nowhere near ready to pour.

Yes, it’s a disappointing result for the Blendtec, but it’s very likely the Blendtec Smoothie program is not the best way to make Banana Milk.  As with the issue that I had trying to use the Blendtec to make powdered parmesan cheese like I do with my Vitamix, it’s likely that part of the issue is my lack of familiarity with the Blendtec.   I’ll move on and try some of my other favorite recipes and I’m looking forward to hopefully finding some areas where the Blendtec shines.
