Team Vision for Preliminary Detailed Design Phase

During this phase, the team continued to refine and improve upon the design previously presented. The team also made a trip to Worm Power in Avon, NY, a local vermi-composting facility, in order to get a better feel for the best way to implement composting into an automated system. This trip yielded many new considerations for the team and helped us to identify major issues that we will be facing and some issues we should focus more heavily on. Some of these include the moisture and aeration rate that the compost has in order to efficiently compost within the system. During this phase we also began collecting data on our compost piles as we had previously planned. However, the data has yet to yield significant results. We are currently investigating the cause of the lack of actual composting action. Finally, we were able to get a sample of auger stock which we will be implementing into the new design and built a prototype feasibility device in order to simply test the required torque needed in order to move the amount of material we are looking for. The tests yielded a very low torque requirement and the auger was able to easily move all of the material we put into it. Ultimately, we were able to accomplish everything we had hoped. However we were not able to obtain significant data for the compost process, so we will be modifying our methods for the next phase.

Plans for next phase

Prior to the end of the semester, the team is hoping to finalize all of our designs and get final dimensions and schematics for all of the sub systems. Additionally, we will be aiming to perfect our composting process in order to gain a sensor benchmark. We will also be getting prototypes for the systems started and materials will be selected for each or our components. Hopefully we will be able to find a motor for our auger and get started on the assembly of that system since it is easily the most complex system we are dealing with. We will also start thinking about incorporating our aeration and venting into the reactor chamber.
