[0015] The present invention provides a quick-freezing device for surimi products by improvement, which has the following improvements and advantages compared with the prior art: First, the present invention arranges a quick-freezing mechanism. The motor drives the rotating wheel and the rotating sleeve to rotate through the driving shaft and the driving wheel. The rotating sleeve rotates to drive the fixed frame, the fixed rod, the movable sleeve and the fixed box to rotate. When the rotating wheel contacts the arc plate, the rotating wheel moves on the arc plate and rotates. The rotation of the rotating wheel drives the cylindrical rod to rotate in a circle. The rotation of the cylindrical rod drives the movable rod to move back and forth through the L-shaped connecting rod. The movement of the movable rod drives the flat plate and the fixed plate to move back and forth. The fixed plate and the flat plate move upward. The fixed plate can move the top of the net box. The flat plate moves upward to push the liquid nitrogen above the flat plate to contact the bottom of the net box through the strip holes, so that the bottom of the net box can fully contact the liquid nitrogen, thereby improving the freezing effect of the liquid nitrogen on the surimi product.

[0016] Second, when the fixed column contacts the hypotenuse of the extrusion plate, the extrusion plate squeezes the fixed column and moves downward as the fixed column continues to rotate. The movement of the fixed column drives the movable sleeve and the fixed box to move downward. The downward movement of the movable sleeve drives the connecting spring to stretch and elastically deform, so that the fixed box enters the liquid storage tank, and the liquid nitrogen in the liquid storage tank freezes the surimi product, and the surimi product can be placed in the liquid nitrogen for freezing.

[0017] Third, when the fixed column contacts the hypotenuse of the extrusion plate, the fixed column first drives the extrusion plate to move upward, the movement of the extrusion plate drives the bracket and the sliding cap to move, the movement of the sliding cap drives the telescopic spring to stretch and elastically deform, the movement of the bracket drives the mounting rod and the stirring plate to move upward, and when the fixed column is away from the extrusion plate, the telescopic spring drives the sliding cap, the bracket, the extrusion plate, the mounting rod and the stirring plate to reset, so that the stirring plate can stir the liquid nitrogen to make the liquid nitrogen more uniform.

[0018] Fourthly, when the weight of the surimi product increases, the sliding rod of the present invention moves downward, and the movement of the sliding rod drives the installation spring to stretch and elastically deform, and the movement of the sliding rod drives the extrusion block to move downward, and the movement of the extrusion block drives the installation plate and the movable plate to move away from the sliding rod, and the movement of the movable plate drives the driving shaft, the motor and the driving wheel to move, and at the same time, the movement of the movable plate drives the extrusion spring to compress and elastically deform, and the sliding rod moves downward and drives the rotating wheel to move downward. Since the diameter of the rotating wheel gradually increases from bottom to top, the rotation speed of the rotating wheel and the rotating sleeve driven by the driving wheel decreases, so that the time that the surimi product stays in the liquid nitrogen is increased to increase the contact time, thereby improving the freezing effect of the surimi product.
