Abstract: A high-precision control system and method for shipborne cryogenic flash freezing of an aquatic product using liquid nitrogen is described. The system may include a main control system, a display unit, a liquid nitrogen supply system, a valve control unit, an acquisition unit, and a power unit. A flash freezing process is divided into four stages: a precooling stage, a flash freezing stage, a deep freezing stage, and a thermal insulation stage. Different cooling rates and flash freezing times are used for different stages, where a cooling rate is used in the flash freezing stage is the highest, a cooling rate used in the deep freezing stage is next, a cooling rate used in the precooling stage is the lowest, and an ambient temperature in a device is kept stable in the thermal insulation stage.

Abstract: A pneumatic proportional valve includes a torque motor and a pneumatic rotary valve. The torque motor includes permanent magnets, magnetically permeable yokes, an upper armature, a lower armature, an upper skeleton, a skeleton column, a lower skeleton, an exciting coil, a coil skeleton, a spring support, a spring plate and load springs. The torque motor has a single coil structure with an axis of the exciting coil coinciding with a rotation axis of the armatures, and the coil is arranged between the upper armature and the lower armature. The torque motor has the upper armature and the lower armature, and the upper armature and the lower armature have a total of four armature arms, which can form eight air gaps with an upper one and a lower one working in pair, form four pairs of magnetic circuits in parallel with each other under the excitation of a control coil.
