Abstract
This research was conducted to determine the effect of performance on the use of the parallel distribution evaporator on ice cream roll machine. This research was made using 3 variations of parallel distribution evaporator model, where each model has a different shape. Model 1 has 3 inputs and 3 outputs, Model 2 has 2 inputs and 2 outputs and Model 3 has 1 inputs and 1 output. Evaporator is made with a size of 45 cm x 40 cm x 4 cm from stainless steel thickness 0.3 mm, so that most of the products produce crystallization then it needs to be set points at a temperature of -180C. the effect of the superheat process, where the smaller the superheat that occurs, the temperature in the evaporator can be more stable. Based on the results of the testing that has been done, the COP systems work performance is 4.3, 3.6, and 3.4 for each evaporator model. Efficiencies generated respectively for the evaporator model of 86%, 78% and 76%.
