In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] Referring to Figure 1 and Figure 2 , the present utility model relates to a drying device before processing shrimp oil microcapsules. The main structure includes a drying tank 1, and the drying tank 1 is a hollow tank structure. A liquid inlet pipe 2 is provided on the drying tank 1. The shrimp oil to be dried enters the inside of the drying tank 1 from the liquid inlet pipe 2 under the drive of an oil pump. An exhaust pipe 3 and a liquid outlet pipe 4 are respectively provided at the top and bottom of the drying tank 1. The water vapor at the evaporation place is discharged from the exhaust pipe 3, and the dried shrimp oil is discharged from the liquid outlet pipe 4. A drying cylinder wall 5 is welded or bolted inside the drying tank 1. A heating component is provided inside the drying cylinder wall 5 to heat the drying cylinder wall 5 by using the heating component, so that the drying cylinder wall 5 has a large drying area, so that when the shrimp oil contacts it, the water in it can be quickly evaporated, thus greatly improving the efficiency of drying the shrimp oil. A liquid spraying ring pipe 6 is provided outside the drying cylinder wall 5, and the liquid spraying ring pipe 6 surrounds the outside of the drying cylinder wall 5. The liquid spraying ring pipe 6 is communicated with the liquid inlet pipe 2, and a plurality of nozzles 7 are communicated with the liquid spraying ring pipe 6. Such a structure enables the shrimp oil to enter the liquid spraying ring pipe 6 from the liquid inlet pipe 2 and then be sprayed from the plurality of nozzles 7 to various positions of the drying cylinder wall 5, so that the distribution of the shrimp oil is more uniform, and further improves the efficiency of evaporating and drying the water in the shrimp oil. The plurality of nozzles 7 are all inclined towards the drying cylinder wall 5 to slow down the splashing phenomenon generated when the shrimp oil contacts the drying cylinder wall 5 and ensure the effect of evaporation and drying. A cooling plate 8 is provided below the drying cylinder wall 5, and cooling water is introduced into the cooling plate 8. A plurality of cooling channels 9 are provided on the cooling plate 8, and the dried shrimp oil passes through the plurality of cooling channels 9. The cooling water inside the cooling plate 8 is used to quickly cool the shrimp oil, so that the dried shrimp oil can seamlessly cooperate with the subsequent microencapsulation processing procedure, avoiding the storage link before microencapsulation processing and preventing the shrimp oil from getting wet again before microencapsulation processing, ensuring the water content requirement during shrimp oil microencapsulation processing and ensuring the embedding rate and quality of the microcapsule powder.

[0022] Preferably, the cross-section of the drying cylinder wall 5 is annular, so that the side surface of the drying cylinder wall 5 is arc-shaped, which makes its surface area larger and the shrimp oil is not easy to remain on the surface. The heating component includes a plurality of heating tubes 10, and the plurality of heating tubes 10 are arranged in an array on the inner side of the drying cylinder wall 5. Such a setting enables the plurality of heating tubes 10 arranged in a circular array to uniformly heat each position of the drying cylinder wall 5, thereby ensuring the uniformity of the drying treatment of the shrimp oil at each position on the drying cylinder wall 5 and improving the effect of the drying treatment of the shrimp oil.

[0023] Preferably, referring to Figure 3 , a steam discharge plate 11 is welded or bolted to the top outside the drying tank 1. An outlet pipe is provided at the top of the steam discharge plate 11, and an exhaust fan 12 is provided in the steam discharge plate 11. The exhaust fan 12 is used to generate the suction force for steam discharge. The exhaust pipes 3 are a plurality of pipes surrounding the outside of the drying cylinder wall 5, and the plurality of exhaust pipes 3 are all communicated with the steam discharge plate 11. Such a structure enables the plurality of exhaust pipes 3 to be evenly distributed above each position of the drying cylinder wall 5, so that the water vapor at the evaporation place can be quickly discharged by the exhaust pipes 3, preventing the water vapor from gathering and falling back into the shrimp oil again, thereby ensuring the timeliness of steam discharge and the drying effect.

[0024] Preferably, the bottom of the drying tank 1 is a tapered shape that is wider at the top and narrower at the bottom, so that the shrimp oil is more concentratedly stored at the tapered bottom. The liquid outlet pipe 4 is communicated with the bottom of the taper, and a valve 13 is provided on the liquid outlet pipe 4. The valve 13 can adopt any structure on the existing market. Such a structure can use the valve 13 to close the liquid outlet pipe 4, so that the dried shrimp oil is temporarily stored at the tapered bottom to achieve rapid cooling. After the temperature reaches the specified requirement, the valve 13 is opened to enable the shrimp oil to enter the subsequent microencapsulation processing procedure, realizing the effective cooperation between the drying of the shrimp oil and the subsequent microencapsulation procedure.

[0025] Preferably, referring to Figure 4 , water inlet pipe 14 and water outlet pipe 15 which are communicated are respectively provided at both ends of the cooling plate 8. Cooling water at a lower temperature enters the cooling plate 8 from the water inlet pipe 14 and is discharged from the water outlet pipe 15 after cooling. A plurality of communicating cooling fins 16 are provided on the cooling plate 8. After the cooling water enters the cooling plate 8 from the water inlet pipe 14, it simultaneously enters the plurality of cooling fins 16. The cooling fins 16 have a large surface area, so they can better contact and exchange heat with the shrimp oil. The cooling channel 9 is composed of the areas between adjacent cooling fins 16. Such a structure greatly increases the contact area between the cooling water and the shrimp oil flowing through the cooling channel 9, improving the cooling effect and cooling speed.

[0026] Preferably, a plurality of support rods 17 are welded or bolted to the bottom of the cooling fins 16. The support rods 17 extend to the bottom end of the cone. On the one hand, the support rods 17 can provide support for the cooling fins 16 to ensure the structural firmness of the cooling fins 16. On the other hand, they can also ensure contact with the shrimp oil temporarily stored at the bottom of the cone, transfer heat to the cooling fins 16, so that the shrimp oil temporarily stored at the bottom of the cone is further cooled, further improving the cooling effect of the shrimp oil.

[0027] Working principle: The structure of the present utility model is provided with a drying cylinder wall 5 in the drying tank 1. The shrimp oil entering from the liquid inlet pipe 2 is evenly sprayed on the drying cylinder wall 5 through a plurality of nozzles 7 on the liquid spraying ring pipe 6, so that the shrimp oil is more dispersed. The heating component inside the drying cylinder wall 5 is used to fully heat the dispersed shrimp oil, so that the moisture in it quickly evaporates and is discharged from the exhaust pipe 3 at the top, thus greatly improving the drying efficiency, reducing the water content of the shrimp oil, and reducing the influence on the subsequent microencapsulation processing procedure; a cooling plate 8 is provided below the drying cylinder wall 5, and a plurality of cooling channels 9 are provided on the cooling plate 8. The dried shrimp oil passes through the plurality of cooling channels 9 and then enters the bottom of the drying tank 1 and is discharged from the liquid outlet pipe 4 at the bottom. The setting of the cooling plate 8 can quickly cool the shrimp oil flowing through the cooling channels 9, so as to be seamlessly matched with the subsequent microencapsulation process, avoid the shrimp oil getting damp again due to unnecessary intermediate links, ensure the water content requirement during the microencapsulation processing of the shrimp oil, and further ensure the quality of the microcapsule powder.
