Abstract:
The body, legs and claws of crab were classified. Shell and meat were separated by belt extrusion, roller extrusion and vacuum suction. The yield, separation efficiency and crab meat quality were used as evaluation index. The research results indicated that belt extrusion was most suitable for shell and meat separation of crab body and yield of crab meat can reach to 68.2%. Separate efficiency can reach to 50 kg/h and crab meat had a best quality. Roller extrusion was most suitable for shell and meat separation of crab legs. The yield of crab meat was 35.8%, and separate efficiency was 6.8 kg/h. The crab meat showed a best quality. Vacuum suction was most suitable for shell and meat separation of crab claws. The yield of crab meat was 44.1% and separate efficiency was 5.1 kg/h. The crab meat had a best quality.
