Oh, I love sweet potatoes, thank you for the suggestion backpack.
I have started preparing my own frozen fruits, and that makes sense. I would say that to me smoothness and creaminess are different. My first attempts at green smoothies were creamy but not smooth from the green bits that didn't process all of the way.
As far as the food processor, have no clue. But according to this
recipe, it's possible. The part I didn't want to partake in is the straining at the end.
I am beginning to think that the RPM of the Vitamix is a big part of the equation that allows it to make the finished product that I desire (the whole food is utilized and homogeneous with the entire mixture). My Universal Kitchen Machine was not designed to spin that fast. It's powerful enough. The blender easily and rapidly crushes ice, and therefore it makes a great slushie. The mixer attachments and bowl can easily knead quantities of stiff dough to make 6 loaves of heavy whole wheat bread at once. It's just no where near as fast as the Vitamix.
I know that Vitamix also has something different going on with the blade design compared to a food processor. The blades both pull the ingredients from the top downward to them, but also allow the even mixture of ingredients, and don't allow bits to get stuck underneath them. My Cuisinart 3 cup, mini food processor (the only one I have and also surprisingly powerful) has a blade on one plane. It doesn't pull anything up or down, just hits whatever is in it's path. I have had thin slices of softer foods get stuck under the plane of the blade. I have successfully made yummy nut butter in it as well as processed a myriad of foods for various purposes. I wouldn't want to drink anything I made it in, but a better food processor may be a different story.
I would try the food processor, maybe make a small batch and resolve that whatever you are trying to make could be put into muffins or something if it didn't turn out like you were hoping.
If you are looking for an actual juicer, the
Breville Juice Fountain Compact is excellent. I have had mine for about 7 years +/-. It makes quick work of both juicing and clean up. It extracts juice very well for a juicer of it's price. The design is nicely thought out for the juicer, it's pitcher and cleaning tool in every way. It was an affordable way for me to give my kids more veggies than they would eat. And I knew what was in it vs. some of the commercial veggie/fruit juice blends.
Even though I now have my Vitamix, I will be keeping the Breville, I love it that much!
When you try making juice, please share, I'm curious and others may want to know.
Um, on another note, Tom, would you consider making a padded travel case for my Vitamix? I've decided that I must have it wherever I go. I love teh smoothie!
