FIKRI FAHLEVI NASUTION, NIM. 2210247004, Design of Air Blast Freezing System with Cascade Refrigeration System Using R290/R32 to Prevent Decay of Black Tiger Shrimp, supervised by Awaludin Martin and Rahmat Iman Mainil.
Shrimp is Indonesia's main export commodity, with 2021 production reaching 1.21 million tons or IDR 79.21 trillion. The urgency of this research is that although the production increased by 9.20% from the previous year, only 20.89% of this amount was exported. This is due to technological limitations in maintaining the freshness of shrimp, due to the growth of microorganisms such as bacteria, fungi and yeast. In facing these challenges, it is necessary to develop a quick freezing system at temperatures of -18℃ to -52℃ to inhibit the growth of microorganisms using a cascade refrigeration system at temperatures up to -40℃ using environmentally friendly refrigerants, namely R290 and R32.
The research objectives of this research are (i) designing an Air Blast Freezing (ABF) system with a capacity of 5kg, (ii) making an ABF prototype based on the design results, (iii) testing and analyzing the ABF prototype. In order to achieve the objectives of this research, the method used includes the design stage, where the ABF system is designed based on the cooling load and final product temperature. The manufacturing stage is the production stage of ABF by assembling the components of the ABF system into a single unit. The testing stage is carried out to evaluate the design results based on the test results obtained and data analysis is carried out. The results show that the evaporator temperature reaches -42.37 ℃, so that shrimp weighing 5 kg can be frozen at a temperature of -33.78 ℃ with a test time of 6 hours. The experimental COP and design COP are 1.334 and 1.548, respectively.
