    I have tried searching extensively but so far no luck as I am not totally sure what I am looking for 🙂

    Consider a dairy pasteurizer.  They are capable of precise temperature control and incorporate low shear paddles.  They have airspace heaters and water jackets so they heat precisely and quickly. I have a 30 gallon and two 4 gallon pasteurizers.  They’re designed to an extremely high standard for sanitizability, because of the demands for milk processing.  And I have a high volume systolic transfer pump so I can heat both phases to temperature and then transfer oil to water (because of the relative volumes that’s the direction i have to go) and apply high shear as the oil enters, them turn on the low shear mixer.  I can even add cold water to the pasteurizer jacket if I wanted to cool the emulsion down faster.  There’s minimal exposure to air, very clean process.

    Mind you this isn’t a cheap solution, but it’s a really, really good one.  I happened to operate a dairy on my farm at one time so I had the equipment.  But if you can find this equipment used, it’s a better solution than most I’ve seen, shy of a fancy dedicated plant.

    Hi @Julie50 - I have been looking at those mixers as well.  It’s possible you have already bought it, but if you have not, beware of 220v machinery to use  in the 110v US.  For smaller appliances when you travel (your phone, etc.), an adaptor/converter for 110v-220v is fine, but for a high shear mixer, which draws a lot of power and has a powerful motor, I wouldn’t take the chance.

    There are issues with both voltage and frequency, but my understanding is that frequency is the biggest issues for appliances with powerful motors.  In the US the frequency is typically 60 Hz, while in China (though it can vary by region I believe), the frequency is 50 Hz.  Moreover, while voltage can be altered with an adaptor/converter, there is nothing that can alter frequency. This means that the motor could blow out very easily if you run this mixer in the US.  

    I’m sorry to be a bummer, as I realize that these mixers cost far less than those available here.  As I said, I was looking at them very carefully (and longingly), but even $700-$1500 is a lot of money to waste if the mixer just blows up on you, so ultimately, I decided not to take the chance.

    I am not an electrician, and much of what I am telling you was gleaned from Wikipedia and my BF who dabbles in electricity, so I could well be wrong,  In fact, I HOPE I’m wrong, bc I would really like to buy one of these!  I just can’t afford a Silverson or anything like it at this point. Good Luck with everything, and I would love to know how it all turns out.
