The juicer we showed you wednesday didn’t work that good. Today, we brought something different: a cheap, secondhand blender.
We tried to blend the milk bottle HDPE in different sizes and in both straight and fumbled state. This had some mixed results (we will eleborate these next week), but most important: it worked!
Next thing, we have to discover with size the milk bottle has to be reduced to, to be able to extrude it. Also, we will have to look at the consequences of the impact the knives have with the plastics. Although the temperature changes seemed to be pretty low, there knives were getting a bit warmer. Does it change the material properties of the plastic due to temperature changes? How fast will the knives go blunt? What can we do to prevent the heating (for example adding water to the plastic while blending or putting the plastic in a refridgerator)?
Have a nice weekend!
