Microwave thawing equipment is used to thaw frozen food products such as fish products. Fish products are rich in protein and multivitamins and are a nutritious product.
Frozen fresh fish
A disadvantage of prior art defrosting devices is that it is difficult or even impossible to ensure an optimal temperature distribution within the sump. The consequence of this is that due to the uneven distribution of heat temperature in the defrosting tank, it is possible to form large ice/fish aggregates in some places of the tank. The transfer of fish products or fish aggregates must be stopped or not thawed when the fish product or fish aggregates that are transported reach the output.

The marine fish microwave thawing machine also includes an air supply source that is longitudinally disposed along the reservoir and below it in a substantially equidistant manner for supplying air into the liquid.
The equipment further includes the feature of an air supply source for supplying air into the liquid longitudinally disposed along the reservior and in a substantially equidistant manner therebelow, which is particularly advantageous, because a large number of relatively small bubbles are formed at the bottom of the reservoir, they together form a large surface area which is very advantageous for providing buoyancy to the food in the liquid. This is especially relevant when the process is to thaw smaller fish products such as shrimp, which may sink easily and concentrate at the bottom of the tank when transported from the supply end towards the outflow end of the tank. By blowing air into the liquid it is ensured that the shrimp (and other smaller fish products) are distributed at least to some extent in the liquid. Moreover, blowing air into the reservoir breaks up the possible stratified flow across the reservoir. This ensures a more uniform temperature distribution within the reservoir.
The supply of frozen food into the reservoir 101 depends on the type of frozen food. In the existing technology thawing equipment, the supply of frozen food occurs at one end (supply end) of the reservoir 101, and hot water is also injected into the reservoir here. However, for fish products such as shrimp, typically in the form of frozen ice, as discussed above, it is more advantageous to supply the blocks from the sides into the reservoir 101, as indicated by arrow 115. In this way, the ice cubes are evenly distributed in the storage tank 101 so that the thawing is much faster rather than supplying the entire ice cubes at the supply end 107 into the reservoir 101, they may be easily bonded together at the supply end 107. Moreover, by supplying the entire ice cube on one side, the liquid cools down very quickly and the temperature becomes too low. The thawing of the shrimp may last for several hours. After thawing, the spiral blade begins to rotate and the thawed shrimp is sent out of the reservoir. To minimize labor, system 100 May also include an electric conveyor belt (not shown) for pallets filled with frozen blocks, and a scissor lift at the supply end or side of the storage tank.The operator can adjust the height of the pallet when supplying the block to the tank.
The thawing process can be fully computer controlled and the operator can input various control parameters to the computer system 112 via a suitable user interface. By inputting appropriate parameters, the operator can simply adjust the thawing process, which can be the liquid temperature (target temperature), the frequency of air inflow as the thawing time elapses, the (heat) temperature control the influx of liquid, the speed of the spiral blade and hence the conveying speed, the length of the reservoir, the type of food to be cooled or thawed and so on. The appropriate software is programmed to receive the various input parameters from the operator and the temperature values from the thermometer 111 to adjust the flow of the heatined reagent into the liquid.
Figure 2 shows a cross-sectional view of the apparatus 100 of Figure 1, a portion of the helical blade 102, the rotary shaft 202, and the drive motor 103 are shown, the drive motor 103 operates the rotational speed of the rotary shaft 202 and thus the rotational speed of the helical blade 102.
