In order to improve the utilization value of Antarctic krill, with self-designed Antarctic krill sheller taken as the object of study, ship loading experiment was carried out for the key components and process parameters such as the roller length, roller clearance and feed rate; sensory evaluation and yield determination were carried out for the shelled Antarctic krill to determine the optimal combination of roller clearance, roller length, feed rate and krill storage period. The results showed that when the roller length was 1.0m (A2), the roller clearance was 1.0mm (B2), the feed rate was 125 kg/h (C3) and the storage period was 15min (D1), the experimental indicators were the best; when the combination of A2B2C3D1 was used in actual production, the yield of Antarctic krill reached 24%. The study showed that the equipment could improve the shelling efficiency of Antarctic krill, and improve the level of automation during high-value processing of Antarctic krill, thus promoting the industrialization process of Antarctic krill.
