Detailed Description

In order to further describe the technical means and effects adopted by the utility model for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the utility model with reference to the attached drawings and the preferred embodiment.

As shown in fig. 1 to 3, a thawing device for fish processing comprises a frame 1, a first rotating roller 2 and a second rotating roller 3; the first rotating rollers 2 and the second rotating rollers 3 are arranged in the frame 1 in an array manner, the first rotating rollers 2 and the second rotating rollers 3 are arranged at intervals in a staggered manner, the second rotating rollers 3 are arranged between two adjacent first rotating rollers 2 in a horizontal direction, the first rotating rollers 2 are arranged at the tops of the second rotating rollers 3 in a vertical direction, a curve transmission channel is formed between the first rotating rollers 2 and the second rotating rollers 3 in the staggered manner, the curve transmission channel can screen unfreezed fish which are unfrozen to a certain extent, the blocky frozen fish is unfrozen in the unfreezing groove of the frame 1, after a single unfrozen fish is separated from the blocky frozen fish, part of the unfrozen fish is still in a harder state, and the other unfrozen fish is in a softer state, the single unfrozen frozen fish is unfrozen under the rotation action of the first rotating rollers 2, along with the steering force of the first rotating roller 2 is transmitted to the second rotating roller 3 from the two adjacent first rotating rollers 2 in a rotating way, as the second rotating roller 3 and the first rotating roller 2 are installed at intervals in a staggered way, single frozen fish is transmitted from the thawing tank in a curve way, harder frozen fish cannot be screened from the classifying channel, the thawing degree of the fish is distinguished in sequence, the single frozen fish is separated from the thawing tank in time, the influence on the quality of the fish caused by long-time excessive thawing is avoided, and secondly, in order to distinguish the size from the fish, the first rotating roller 2 is installed according to the size of the fish, the size interval between the adjacent first rotating rollers 2 is set to be the distance capable of screening the small fish, the large and small fish are classified in the thawing process at the same time, the subsequent processing flow is facilitated, the processing flow is simplified, and the working efficiency is improved.

As shown in fig. 3, the classification screening and low transmission efficiency are caused by the fact that the harder blocky frozen fish is not blocked between the adjacent first rotating rollers 2, in order to enable the softer blocky frozen fish to enter the transmission channel along with the rotation of the first rotating rollers 2, in one embodiment, a plurality of stirring frames 4 are arranged on the first rotating rollers 2 in an array mode, the stirring frames 4 between the adjacent first rotating roller 2 groups are mutually matched to form a screening channel, so that the stirring frames 4 do not interfere with each other when rotating along with the first rotating rollers 2, the stirring frames 4 can contact the hard unfreezing fish blocked in the first rotating rollers 2 while rotating, so that the principle of the first rotating rollers 2 are accelerated, meanwhile, the stirring frames 4 are in a liquid state in the unfreezing pond along with the rotation of the first rotating rollers 2, and simultaneously are also in contact with the blocky frozen fish, so that the blocky frozen fish is slowly decomposed into single unfrozen frozen fish, the single unfrozen frozen fish has a movement like the stirring frames 4 under the rotating action of the stirring frames 4, and finally enters the transmission channel from the two adjacent stirring frames 4, and can be unfrozen in the thawing pond at the same time, and the liquid state in the thawing pond can be accelerated, and the unfreezing tank can be quickly and the unfreezing liquid can be quickly and quickly decomposed.

As shown in fig. 2, in order to avoid that the frozen fish blocks directly contact with the first rotating roller 2, so that the first rotating roller 2 needs higher power to complete rotation when rotating, in an embodiment, a supporting plate 5 is further arranged in the frame 1, the supporting plate 5 is positioned at the top of the first rotating roller 2, when the frozen fish blocks are thawed in a thawing pool, the supporting plate 5 bears most of the gravity of the frozen fish blocks, the frozen fish blocks can be effectively prevented from directly contacting with the first rotating roller 2, the first rotating roller 2 only needs less power to complete separate sunning and transmission of the frozen fish blocks, a plurality of supporting columns 51 are arranged in an array in the supporting plate 5, the supporting columns 51 are spaced by a certain distance, the distance is just matched with the stirring frame 4, the rotation of the first stirring frame 4 is not influenced, and single frozen fish separated from the frozen fish blocks can enter a transmission channel, so that the supporting function of the frozen fish blocks can be played, and the transmission of single frozen fish blocks cannot be influenced.

As shown in fig. 2, after the unfreezing fish is completely unfrozen and transmitted, in order to defrost the unfrozen fish in the unfreezing pond, excessive unfreezing is caused, after the unfrozen fish with poor quality is in an S shape and is transmitted from the transmission channel during subsequent processing, the unfrozen fish enters the bottom of the unfreezing pond, in order to avoid the blocky fish in the unfreezing pond to be accumulated at the bottom of the unfreezing pond after being transmitted through the transmission channel, the transmission effect is poor, in one embodiment, a containing box 7 is arranged, the containing box 7 is communicated with an opening arranged at the bottom of the frame 1, a single unfrozen fish entering the bottom of the unfreezing pond at the second transmission channel can enter the containing box 7 through the opening, and the containing box 7 is smaller than after containing and unfreezing and screening, can reduce the containing capacity in the unfreezing pond by components during the transmission process, and the speed is accelerated.

As shown in fig. 1, in order to complete thawing of the frozen fish in block form, in one embodiment, a driver 62, a spraying device 61 and a thawing liquid unit 63 are further included; the spraying device 61 is arranged above the frame 1, the driver 62 is arranged on the frame 1, the driver 62 is arranged between the defrosting liquid unit 63 and the spraying device 61, the defrosting liquid unit 63 is filled with solution such as white vinegar which is helpful for defrosting, the defrosting liquid unit 63 is started, and the driver 62 is started to spray the defrosting liquid in the tank 6 to the defrosting tank through the spraying device 61 so as to defrost the fish to be defrosted.
