| Pre-designed ice maker have a unique ice-making system by shooting water vertically upward on the surface of the ice mold using nozzles. This machine has been designed in such a way, but in operation is still not optimal. The resulting ice has not formed as desired. This is caused by the resulting nozzle shot, eroding the ice layer formed by the next flow of the nozzle shot. With these nozzle shooting characteristics will complicate the process of making ice. This final project examines the experimental review of the nozzle dimension in "Ice Maker". The method used is the experimental method, by measuring the speed of each nozzle, observing the ice produced, and measuring the time of ice formation for 1 cycle. The dimensions of the nozzle are then adjusted by adjusting the pump's ability and cooling rate in "Ice Maker", and nozzle shooting characteristics. Based on experimental, no 0.5 mm diameter nozzle and nozzle shooting characteristics with smooth bursts. With nozzle changes and nozzle shooting characteristics, ice-breaking times are much better, with an average of 50 minutes for 1 cycle compared to the previous 2 hours for ice formation in 1 cycle, and the resulting ice shape is good. |
