Abstract

The snakehead fish is a type of fish that contains abundant albumin as a source of animal antioxidants. To obtain albumin extract, the meat of the snakehead fish will be processed using a drying method until it is produced in powdered form. A heat pump is a device that transfers heat from a low-temperature medium to a high-temperature one. The purpose of this research is to compare the efficiency of drying snakehead fish, energy consumption, drying time, and the quality of the dried snakehead fish using variations of open cycle heat pumps against closed cycle. The drying of 5 kg of snakehead fish will be tested on a heat pump with a closed cycle using refrigerant R32, until the moisture content of the specimen, as read by the DHT21 sensor, drops to 5%. From this research, it was found that the performance of the drying device in a open cycle is most efficient with an average value of 16.17, while in a closed cycle it has an average value of 10.15. The moisture content reached in the Closed and Open cycles is 5% from the initial moisture content of 78.19% at a maximum drying temperature of 50.6ºC, so the albumin content present in the snakehead fish will not be damaged
