As shown in fig. 1 to 3, the present invention provides a thawing apparatus for frozen food processing, comprising: a steam generator 1 and a defrosting tank 2;

steam generated in the steam generator 1 enters the air inlet pipe 3 through the vent pipe 4, and the air inlet pipe 3 is positioned on the inner wall of the thawing box 2 and conveys the steam into the thawing box 2. The steam entering the defrosting tank 2 humidifies the food to be defrosted in the defrosting tank 2, so that the food to be defrosted is defrosted after being wetted and defrosted. In order to make the steam diffuse to the area in the defrosting tank 2 more, as a further scheme, the air inlet pipe 3 is connected with a vent pipe 31, the vent pipe 31 is provided with a plurality of air outlet pipes 32, and the outlet of each air outlet pipe 32 faces the defrosting mechanism. The air supply mechanism 8 installed at the upper end of the thawing box 2 blows air into the thawing box 2, so that the interior of the thawing box 2 keeps at a lower temperature, meanwhile, humid air in the thawing box 2 can be circulated by the air supply mechanism 8, and the air supply mechanism 8 continuously conveys cold air to food to be thawed in the process of thawing, so that the food to be frozen in the thawing box 2 is continuously thawed. Through the mode of humidification unfreezing, compare the mode of direct heating or direct soaking, can make the refrigerating fluid on the frozen food cool down gradually and melt, avoid direct heating to melt and lead to the nutrient composition in the frozen food to run off rapidly. The number of the air supply mechanisms 8 can be 2-3, and the air supply mechanisms are specifically matched with the size of the defrosting box 2 according to the number of the air supply mechanisms. As a further scheme, the air supply mechanism 8 comprises an air supply fan 81 installed on the thawing box 2, a mounting hole 82 is formed in the thawing box 2, an air supply pipe 83 is arranged in the mounting hole 82, and the air supply pipe 83 is connected with an air outlet of the air supply fan 81. Two air blowing mechanisms 8 are shown in fig. 1, and in the air blowing mechanism 8 provided in this embodiment, the air blowing amount of the air blowing fan 81 is set in advance by the control box 13 to meet the use requirement. As a further aspect, the thawing apparatus of the present invention further includes: the temperature sensor and the humidity sensor are arranged in the unfreezing box 2, the temperature sensor and the temperature sensor are connected with a control box 13 installed on the unfreezing box 2, and the control box 13 is connected with the driving mechanism 7, the air supply mechanism 8 and the conveyor 6. Wherein, temperature sensor and humidity transducer are not drawn in the figure, and the controller in control box 13 is to the electronic component electricity connection in the thawing apparatus that this application provided to, and realizes automated control. The specific control mode is the conventional control mode, and is not detailed here.

In this implementation, feed inlet 5 department that the right side of case 2 that unfreezes set up is provided with conveyer 6, and when the operation, will wait that the food that unfreezes places on conveyer 6, carries to feed inlet 5 department from the one end of conveyer 6, and on the mechanism that unfreezes will be placed to the food that will wait to unfreeze from feed inlet 5 department manual work. As a further solution, a curtain 14 is installed at the upper end of the feeding port 5, and the curtain 14 extends above the conveyor 6. The damp and cold air in the defrosting tank 2 can be retained in the defrosting tank 2 by the curtain 14, so that the damp and cold air is prevented from flowing out of the defrosting tank 2. The front side of the thawing box 2 provided in the application is provided with a driving mechanism 7, and the driving mechanism 7 is used for driving the thawing mechanism to rotate, so that food to be thawed can rotate and is in contact with water in the thawing water tank 10.
