Abstract
The present invention relates to a method and a device for ship-borne freezing of marine products after treated by highly activated water and nondestructive sensing of ice crystals. Through treating the seawater with atmospheric plasma in a certain atmosphere and introducing the tail gas from plasma reactor into the seawater in tail gas collecting device, the highly activated water is obtained. After cooling by the ship-borne refrigeration system, the cooled highly activated water can be used to cool and sterilize the captured marine products timely. During the following freezing processes, both the ultra-high frequency (UHF) electromagnetic field system and pulsed ultrasonic monitoring system are applied simultaneously, which can not only effectively reduce the size of ice crystals and the juice loss of the frozen products during thawing, but also inhibits the thermal effect of electromagnetic field.
