Consider the processing plant of a large cranberry cooperative. The plant receives $1,500$ barrels of cranberries each hour, $70\%$ wet$-$harvested berries, and $30\%$ dry$-$harvested berries. At the plant, dry$-$harvested and wet$-$harvested berries are processed differently. All berries are received at a central receiving station. The station has five docks where trucks unload the berries. It takes about $8$ minutes to unload one truck. The average truck has about $75$ barrels of berries on it$.$ After the receiving station, dry berries are moved to destoning. Wet berries do not have to be destoned. There are three machines at destoning, each of which can process $1500$ barrels per hour. Next comes dechaffing, a step that needs to be completed for both dry$-$harvested and wet$-$harvested berries. There are three dechaffing machines, each of which can process $1,500$ barrels per hour. After dechaffing, the wet$-$harvested berries move on to the dryer. The dryer can process $600$ barrels per hour. Dry$-$harvested berries do not have to be processed at the dryer. Finally, all berries need to move through the separator. The separator can handle $1,200$ barrels per hour. Where in the process is the bottleneck? Use barrels per hour as the performance metric.
