EXAMPLE III

The same or corresponding components in this embodiment as those in the above embodiment are given the same reference numerals as those in the above embodiment, and only the points different from the above embodiment will be described below for the sake of convenience. This embodiment differs from the above embodiment in that:

further, as shown in fig. 11 to 12, the crushing assembly 41 includes a plurality of sets of counterweight hammers 411 sequentially arranged along the length direction of the rotating shaft 31 and sleeved outside the rotating shaft 31, and the adjusting assembly 42 includes a salt squeezing hose 421 vertically arranged downwards and passing through the separating assembly 23, a storage bin 422 arranged above the storage barrel 11 and communicated with one end of the salt squeezing hose 421, and two sets of squeezing blocks 423 arranged on the counterweight hammers 411 and located at two sides of the salt squeezing hose 421;

the salt extruding hose 421 collides with the two sets of extruding blocks 423 at intervals under the impact of the frozen food 100, so that the air in the salt extruding hose 421 is extruded;

the salt squeezing hose 421 is provided with a one-way valve a4211 and a one-way valve b4212, air squeezed by the salt squeezing hose 421 enters the storage bin 422 through the one-way valve a4211, and air in the air enters the salt squeezing hose 421 through the one-way valve b 4212.

A water outlet assembly 4221 is arranged in the storage bin 422, wherein the water outlet assembly 4221 comprises a sealing plate 4223 which is matched with the inner wall of the storage bin 422 and is arranged in a hollow structure, and a connecting spring 2000 which is vertically arranged at the bottom of the storage bin 422 and is used for connecting the sealing plate 4223;

the upper end of the salt squeezing hose 421 is communicated with the upper end of the sealing plate 4223, and one end of the storage bin 422 is provided with a discharge hole 4000.

In the embodiment, by arranging the counterweight hammer 411 and matching with the adjusting assembly 42, when the rotating shaft 31 drives the forward rotating assembly 33 and the reverse rotating assembly 34 to operate to turn over the frozen food 100 left and right, the frozen food 100 is crushed under the action of the counterweight hammer 411, meanwhile, the forward rotating assembly 33 and the reverse rotating assembly 34 swing left and right to drive the counterweight hammer 411 to incline left and right, air in the salt squeezing hose 421 is squeezed by the squeezing block 423, the air squeezed by the salt squeezing hose 421 enters the storage bin 422 through the one-way valve a4211, under the action of air pressure, the sealing plate 4223 communicated with the lower end of the salt squeezing hose 421 moves downwards to form a gap between the sealing plate 4223 and the discharge outlet 4000, and at the moment, the defrosting medium in the storage bin 422 flows out into the storage barrel 11 to further defrost the frozen food 100 therein, and the defrosting efficiency is greatly improved.

It is worth noting that when the defrosting operation is started, the volume of the frozen food 100 is larger, and the impact force is larger, so that the amount of the brine discharged is a little more; on the contrary, in the later stage, after the frozen food 100 is thawed, the impact force of the small frozen food 100 is small, the saline water outlet effect can hardly be achieved, the thawing medium in the cylinder is enough, new addition is not needed, the utilization rate of raw materials is improved, the production cost is reduced, and the control is relatively active.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
