What Properties Are Needed To Produce Perfect Blades For A Blender?

Question

I need this information for my physics coursework...

Answer 1

Well, kinda open ended question, but for humors sake...

If you want to make margaritas, the material properties of the blade should be designed to withstand over time zero degree temperatures (C) and retain 'sharpness' during high velocity impacts with ice. As for the physical shape, you would want to avoid cavitation at many rotary velocities. The design would be dependent upon container parameters as well, a little finite element modeling should sort things out.

On the over hand, if you are interested in macerating boiled pulp, sharpness would become a primary factor. Probably a specific alloy, or layered material that is 'self sharpening' would be the focus.

Two more problems arise. Efficiency could be of concern. If you constantly had large margarita parties, you would be interested in the most rapid ice cruncher, and this may alter blade design. The other would be in chopped nuts. This would need R&D trials to get right, the perfect blade would chop coarse, then fine, all the way to peanut butter.

There you have it!
