To improvement the normative for better processing of Artemia urmiana cysts with Fluidized bed dryer method (FBD) and warm room drying system (W.R), a batch of Artemia cysts that harvested from urmia Lake was choose. Then 30 processing treatments include 6 different drying temperature (28.c, 30.c, 32.c, 34.c, 36.c) on 5 different process time (1, 2, 3, 4, 5, 6 hours) in warm room system and also 20 processing treatment include the same different internal temperatures of previous exams on 4 different process time (0. 5, 1, 1. 5, 2 hours) in fluidized bed dryer was applied. And after the same packing on All of 50 treatments, the desired factors like hatching percent and hatching efficiency and final water content of All treated samples estimated during 15 months and data registered and Analyzed with general Leaner model on spss program. According to results, the cysts samples that process statically with warm room system were better Hatching percent and Hatching efficiency Than Those That dried motional on fluidized bed dryer, also the best process treatment of FBD was the use of 28.c internal temperature for 0. 5 hour and the Best one of (W.R) was 34.c internal temperature for 4 hours. The (W.R) system had higher dry capacity than the FBD and also is cheaper to use. The Best remaining moisture of Artemia urmiana cysts to keep their permanent survive for at Least 15 months was estimated a bout %15. Keywords: Artemia urmiana – Fluidized bed dryer warm room – cysts processing – Hatching.
