I received several 10ml flavors so I thought this would be a good opportunity to show the equipment in use. However, what is occurring is not visible to the eye and occurring at the 2 to 5 micron level. The animation I posted on the other thread is useful to demonstrate the process and far better than I could ever explain it.
I start mixing in whatever size bottle I want to make. While I have a hotplate/stirrer, I am not using it. Instead I use a tiny crock pot and put my bottles in and heat to 140F/60C. It stays at that temp.
While these devices are called hand held, they really are not. They should be mounted on a stand. I made this stand holder so I could set the height and lift it to place the homogenizer shaft in the bottle, and also lift it out for cleaning. (More below) It works very well and is simple.
This is the Pro Scientific model 250. 3/4 Hp 10-30 K RPM. I’ve found that the optimum speed for juice making is around 15K. Any faster and it will produce air bubbles and the product manual warns against this. They are designed to minimize or eliminate aeration. This is the machine mounted on the stand with a 7mm size generator.
For mixing in bottles with the 7mm, I simply cut the rubber bulb off a bottle cap and slip it onto the shaft. Similarly, when using my 10 ml generator I use a rubber flask stopper that I drilled a 10 mm hole in and tapered it to fit and seal a bottle. Whether this is necessary for juice making is questionable, but the companies making these offer similar products. In fact, most homogenizers of this size are used in test or centrifuge tubes. These simply slip on. I would rather have this than have one of my ‘juice mooch’ friends walk in and sneeze or something.
I run the homogenizer for about one minute though half of that is likely enough in small bottles. The manufacturer explains that after all materials have been run through the generator nothing will be accomplished by longer times. The shear effect (particle reduction) is very small.
The manufacturer recommends that the generator be ran in a solvent between uses and that is how I use it. I keep a drinking glass with hot tap water with one drop of dish-washing detergent and another glass of distilled water. I simply lift the homogenizer and run it for 30 second or so in each. I have disassembled the generator and literally licked the parts. No taste whatsoever. By using distilled water to rinse, any residue will mix and not introduce anything unwanted. I disassemble and clean after my mixing session.
I made 7 testers in a little over an hour including heating, cool down, and adding nic while now using an ultrasonic cleaner for this final step. They are completely vape ready.
