When the mixture is heated by steam, the extract is distilled out to achieve separation from the shrimp oil, thereby ensuring the quality of the shrimp oil. The shrimp oil heating tank 1 is provided with a steam outlet pipe 4, and the steam after the mixture is heated is discharged from the steam outlet pipe 4. The steam outlet pipe 4 is connected to the heat medium inlet pipe of the heat exchanger 2. The heat exchanger 2 can be a plate heat exchanger 2 currently available on the market, which is provided with inlet and outlet pipes of a refrigerant and a heat medium, respectively. Steam enters from the heat medium inlet pipe of the heat exchanger 2, and clean air enters from the refrigerant inlet pipe and is mixed with the steam The refrigerant heated by the heat exchange is discharged from the refrigerant outlet pipe 5 in the form of hot air. The refrigerant outlet pipe 5 is connected to the shrimp meal drying tank 3, and the hot air enters the shrimp meal drying tank 3. This structure makes the air entering the shrimp meal drying tank 3 for drying the shrimp meal hot air, and the temperature of the air entering the shrimp meal drying tank 3 is greatly increased, thereby improving the drying efficiency of the shrimp meal drying tank 3, reducing the amount of heat required for drying, improving the utilization rate of steam waste heat, and reducing the overall production cost. The shrimp meal drying tank 3 can adopt the disc heating structure currently available on the market. A plurality of heating discs 6 are distributed in a vertical array in the shrimp meal drying tank 3, and an electric heating wire is arranged inside the heating disc 6, so that the shrimp meal can be dried. When it falls onto the heating plate 6, the moisture therein is quickly evaporated, thereby achieving the drying of the shrimp powder.

The driving shaft 7 vertically penetrates multiple heating plates 6 at the same time, and multiple rake rods 8 are arranged in an array on the driving shaft 7. The rake rods 8 are welded or bolted to the side of the driving shaft 7. The rake rods 8 are in rotational contact with the top of the heating plate 6. The driving shaft 7 is used to simultaneously drive the rake rods 8 on the top of multiple heating plates 6 to rotate, so that the shrimp powder that falls onto the heating plate 6 is quickly spread and pushed onto the heating plate 6 of the next layer, making the entire drying process of the shrimp powder more efficient and smooth. The interior of the driving shaft 7 and the interior of the rake rods 8 are both provided with a connecting rod.
