[0047] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. The following describes various embodiments of the present invention in detail in conjunction with the drawings.

[0048] Example 1

[0049] See also Figures 1 to 16 The present invention preferably provides a technical solution: a corn kernel quick-freezing machine, comprising: a liquid nitrogen freezing generating seat, and a first freezing box 211 installed with the liquid nitrogen freezing generating seat; the first freezing box 211 is provided with a first layered receiving frame 712 and an ultrasonic generating module from bottom to top; and a second freezing box 311 connected to the top of the first freezing box 211, and the second layered receiving frame 711 and a magnetic field generating module are provided inside the second freezing box 311 from bottom to top; the top of the second freezing box 311 is connected to a feed bin, and when the feed bin intermittently scatters corn kernels to be frozen, the liquid nitrogen freezing generating seat releases liquid nitrogen from bottom to top and passes through the first layered receiving frame 712, the ultrasonic generating module in sequence. The sonic wave generating module, the second layered receiving frame 711 and the magnetic field generating module act on the corn kernels; under the action of the magnetic field generating module, the lateral expansion of the ice crystals of the corn kernels is suppressed and the ice crystals are guided to grow in an orderly manner, and under the action of the second layered receiving frame 711, the corn kernels are driven to separate from the middle to the edge in a layered manner and fall onto the first layered receiving frame 712 inside the first freezing box 211; when passing through the ultrasonic wave generating module, the ultrasonic wave generating module releases energy to break up large ice crystals and promote the uniform distribution of small ice crystals; the corn kernels that fall on the first layered receiving frame 712 are enhanced in freezing on the first layered receiving frame 712 and finally progress to the edge in a layered manner and are dispersed and discharged.

[0050] In the corn kernel quick freezing machine, a first layer receiving frame 712 and a second layer receiving frame 711 are introduced, and a magnetic field generating module and an ultrasonic generating module are arranged at corresponding positions;

[0051] Specifically, Figure 1 , 3As shown in , 7 and 8, when the liquid nitrogen freezing generating seat is working, the liquid nitrogen passes through the first layered receiving frame 712, the ultrasonic generating module, the second layered receiving frame 711 and the magnetic field generating module from bottom to top and acts on the corn kernels, and the corresponding corn kernels fall from the feed bin and form convection contact with the rising liquid nitrogen;

[0052] Design point 1 is: the combined effect of magnetic field + ultrasonic wave:

[0053] First, under the action of the magnetic field generating module: water molecules are arranged in a direction, ice crystal nucleation is inhibited, and the orderly growth of ice crystals in corn grains is guided.

[0054] Further, under the action of the ultrasonic generating module: microbubbles are generated through cavitation effect, which releases energy to break up large ice crystals and promote the uniform distribution of small ice crystals.

[0055] The synergistic effect of the two: through the orderly shaping intervention of the magnetic field and the subsequent refinement of ice crystals by ultrasound, the combination of the two achieves the dual optimization of "first suppression and then crushing";

[0056] Design point 2 is: through the structural characteristics of the first layered receiving rack 712 and the second layered receiving rack 711, specifically, under the action of the second layered receiving rack 711, the corn kernels are separated from the middle to the edge in a layered manner, and fall on the first layered receiving rack 712 inside the first freezing box 211. In this process, the corn kernels are gradually dispersed in layers from the middle to the surrounding areas, reducing the occurrence of problems such as mutual adhesion and accumulation, further improving the freezing quality and efficiency, and at the same time completing the material dropping at the edge position. The corn kernels further fall on the first layered receiving rack 712, and the freezing is enhanced on the first layered receiving rack 712, and finally progress to the edge in a layered manner and are dispersed and discharged.

[0057] Example 2

[0058] As another embodiment of the present invention, the first layered receiving frame 712 has the same structure as the second layered receiving frame 711, and the area of ​​the first layered receiving frame 712 is larger than that of the second layered receiving frame 711; the second layered receiving frame 711 includes a plurality of support rings 7111, the radius of the plurality of support rings 7111 increases from the center to the surrounding area, and air holes 7112 distributed in a ring shape on each support ring 7111 are provided for the penetration of liquid nitrogen; the cam transmission mechanism is also provided below the plurality of support rings 7111, and is used for the plurality of support rings 7111 to fluctuate up and down, so that the plurality of support rings 7111 form a receiving surface for corn kernels in a dynamic manner of "water ripples"; the cam transmission mechanism includes a horizontal bar 7113 fixed to the inner wall of the second freezing box 311 and arranged horizontally, and a plurality of vertical rods 7114 penetrating the horizontal bar 7113, wherein , two symmetrical vertical rods 7114 are correspondingly connected to the bottom of the same supporting ring portion 7111, and a rotating shaft 7118 is arranged below the horizontal bar 7113 and rotatably mounted on the inner wall of the second freezer 311, and two groups of symmetrically distributed eccentric cam assemblies are arranged on the rotating shaft 7118, which act on the corresponding side vertical rods 7114 respectively; each group of eccentric cam assemblies includes a plurality of transmission wheels 7116, and the plurality of transmission wheels 7116 are eccentrically fixed relative to the rotating shaft 7118 and are distributed in an inverted "V" shape, and a cam body 7117 is limitedly sleeved on the outside of each transmission wheel 7116, and the top of each cam body 7117 is rotatably connected to the bottom end of the vertical rod 7114 through a connecting shaft 71171; and a motor 511 fixed on the outer wall of the second freezer 311, and the output shaft of the motor 511 passes through the through hole where the second freezer 311 is located and is connected to the rotating shaft 7118.

[0059] In this embodiment, the structural features of the first layered receiving frame 712 and the second layered receiving frame 711 are provided, such as Figure 3 , 5 As shown in FIGS. 7 and 8, since the area of ​​the first layered receiving frame 712 is larger than that of the second layered receiving frame 711, the first layered receiving frame 712 below can completely receive the corn kernels that fall from the edge of the second layered receiving frame 711, and the receiving state can form a W shape, as shown in FIGS. 14. At the same time, the frozen corn kernels are retained thereon and layered again in a stepped state to complete the re-freezing and freezing. Finally, the W shape is switched to an inverted W state with a downward opening, as shown in FIGS. Fig.16 As shown, the frozen corn kernels are scattered from the edge of the first layered receiving frame 712.

[0060] Specifically, take the structure of the second layered receiving frame 711 as an example. Figure 5 , 13As shown, when the rotating shaft 7118 is working, it can drive the plurality of transmission wheels 7116 thereon to rotate. Since the plurality of transmission wheels 7116 are eccentrically fixed relative to the rotating shaft 7118 and are distributed in an inverted "V" shape, when the transmission wheels 7116 rotate eccentrically relative to the cam body 7117, under the action of the limiting sleeve cam body 7117, in conjunction with the up and down sliding of the vertical rod 7114 and the connection relationship of the connecting shaft 71171, the support ring portion 7111 where the vertical rod 7114 is located can be driven to move up and down, thereby realizing that the plurality of support ring portions 7111 fluctuate in the form of water ripples, such as Fig.10 As shown, the thickness of each support ring portion 7111 is greater than the lifting distance of two adjacent vertical rods 7114, thereby realizing the dynamic fluctuation of the bearing surface. Each support ring portion 7111 corresponds to a step layer, and when its cross section is in a W to inverted W state, as shown in FIG. Figures 14 to 16 state, the corn kernels can be frozen in layers and finally removed from the outer edges.

When the control module 312 works to transmit current to the magnetic ring structure 313, a uniformly distributed magnetic field can be generated, which can orient the water molecules of the passing frozen corn kernels, inhibit the nucleation of ice crystals, and guide the orderly growth of ice crystals in the corn kernels.

[0065] Further, under the action of the ultrasonic generating module: and when the second layered receiving frame 711 works in layers, as Figure 5 , 10 As shown in Figures 11, the rotation of the rotating shaft 7118 can further drive the first bevel gear 7119 thereon to rotate, and then drive the mounting rod 812 where the second bevel gear 7120 is located to rotate, thereby making the ultrasonic generator 813 distributed circumferentially on the mounting rod 812 work. The ultrasonic generator 813 is an existing mature technology, which produces microbubble rupture through cavitation effect, releases energy to break large ice crystals, and promotes uniform distribution of small ice crystals.
