The invention provides a marine double-stage compression transcritical CO2 spraying cooking and freezing system, and relates to the technical field of refrigeration and heating circulation and the technical field of seafood processing. The marine double-stage compression transcritical CO2 spraying cooking and freezing system is composed of a double-stage compressor, a gas cooler, an evaporator (refrigeratory air cooler), a sprayer, an intermediate cooler, a gas-liquid separator, a throttle valve A, a throttle valve B, an auxiliary electric heater and a stew pan. High-temperature CO2 fluid at the position of an outlet of the double-stage compressor is used as a heat source to heat seawater to cook seafood, and then CO2 fluid on the evaporator (refrigeratory air cooler) side is used for evaporating to absorb heat to quickly freeze the seafood at low temperature. The system can be applied to offshore freezing processing of the seafood needing to be cooked and frozen such as arctic shrimpsand king crabs, thus, the flavor and the taste of the arctic shrimps and the king crabs are kept, nutrition losses are reduced, and the refreshing time of freezing is effectively prolonged.
本发明提出一种船用双级压缩喷射跨临界CO2熟冻系统。涉及制冷制热循环技术领域以及海产品加工技术领域。本发明由双级压缩机、气体冷却器、蒸发器(冷库冷风机)、喷射器、中间冷却器、气液分离器、节流阀A、节流阀B、辅助电加热器和煮锅组成。利用双级压缩机出口处的高温CO2流体为热源加热海水煮熟海产品,再利用蒸发器(冷库冷风机)侧CO2流体蒸发吸热对海产品进行低温速冻。本发明可应用于北极虾和帝王蟹此类需要煮熟冷冻的海产品的海上冷冻加工,从而保持北极虾和帝王蟹的风味和口感,减少营养流失,有效延长冷冻的保鲜期。
