Plan B

As we move forward with testing, it is important to have a plan B in place. This is a blend between concept 1 and concept 2. Its a smaller pipe with a screw that feeds the plastic pellet into the pineapple. This cuts down cost and would allow for a continual flow rate. The top of the wooden structure is a  hopper for the plastic pellets. The overall  footprint is a little bit wider and the height is the same as the latest rev for concept 2. The thermal results show that the pineapple and the nozzle heat up withing 10 min but the heat does not travel up to the screw.
