Abstract:
The purpose of this research wasto study the factors affecting for using energy to blend pulpy freezingin freezing room. In order to decrease the energy consumption by design of experiment of the ready-to-drink fruit juices factory that perform by using experiences of workers without standardize freezing in nowadays, which lead to high energy costs. This research studied the factors affecting in using energy for freezing process and screening factors by failure mode and effects analysis (FMEA) procedure. 2k factorial design was used in this study, consisted of main 3 factors: temperature, pulp buckets clearance, and pallet clearance, in 3 repeated experiments. The results revealed that, with a 95% confidence level, all factors were significantly had an effect onsaving energy. The recommendations from this study, inthe freezing performance process, should setting temperature for freezing at -23 Celsius, pulp buckets clearance on pallet at 8 centimeter; and pallet clearance in freezing room at20 centimeter. For saving energy in freezing process of 15.29%.
