Toffee properties

[accoladryn]

This is my first time posting, and I have a bit of a problem. I'm trying to figure out a way to aerate a substance of toffee consistency, so a bingham at high temps, and solid at moderate to low temps. The method we're going to try is one where there is an injection point for the air, and then agitators down the line. My problem is, we're copying this method from another process, and i'm having a hard time getting the properties i need to compare the two materials. If i could compare them i could better predict whether this method is going to have any chance of working. I need to get viscosity, primarily, to see if the air will realistically be incorporated into the substance. At the injection point the material will be around 110°C, and from a sample taken, the density is about 1.431 at 85°C. I need to try and find a way to predict the viscosity at the 110°C temp. I have a viscometer, but it's questionable whether it will measure something so high, close to 3000-4000 cP. Any suggestions?? Thanks for any help!
