Evaluation And Modification Of Solid Set Sprinkler System For Hirashima Berry Farms, Jeffrey Hirashima

BioResource and Agricultural Engineering

This project encompassed the evaluation and recommendations for a solid set sprinkler system. This project will determined the distribution uniformity for an existing solid set sprinkler system located on Hirashima Berry Farms. After the evaluation was complete modifications were suggested to the farmer in order to lower watering costs during pre-irrigation and provide salt leaching. The results from the system evaluation show that the current system distribution uniformity is 0.69. The following recommendations and conditions were assumed; normal pre-irrigation practices, an EC threshold of 2.0 dS/m for strawberries, a leaching requirements of 0.15, and an improved DU to 0.80. With …

Design, Construction, And Evaluation Of A Portable Reusable Plastic Container Dumper, Kevin J. Lau

BioResource and Agricultural Engineering

This senior project discusses the design, construction, and evaluation of a portable RPC (Reusable Plastic Container) dumper. This RPC dumper is one piece of a citrus processing system to package citrus. Bee Sweet currently utilizes man power in order to dump its RPCs whereas this design will decrease the amount of man power needed to dump RPCs during high workloads.

The goal of this project was to design, construct, and test a custom fabricated RPC dumper that will decrease the number of people needed to dump RPCs and also the amount of damage on the oranges when being dumped from …
