I use a tiny battery-powered mini drink mixer that is used directly in the
drinking glass. I ordered off the web. You may want to search the web for
one - they are under $10.00(USA). Some come with a travel pouch that can
easily fit in your pocket, purse or silverware drawer. They are sold by a
few
different companies and use 2 AA batteries. "VitaMinder" was one of the
brand names but there are others that look the same as this and may be even
cheaper. It does a great job mixing powdered drink mixes like Barley Green
and it should work very well with powdered soy milk. I generally use the
prepared soy milk so don't have any experience as yet with the powdered milk
substitute to offer any help in that way. Best wishes.
