Abstract
Description
Technical Field
[0001] The utility model relates to the field of Antarctic krill drying, in particular to a rapid drying device for Antarctic krill. Background Art
[0002] During production, Antarctic krill that is caught from the ocean and transported to the workshop after being frozen needs to go through processes such as thawing, cleaning, and drying before it can be crushed and the subsequent shrimp oil extraction steps. When drying the thawed Antarctic krill, it is found that since there is a lot of moisture on the surface of the shrimp after cleaning, the Antarctic krill itself needs to be dried only after the surface moisture is evaporated after entering the drying equipment. The traditional drying method causes Antarctic krill to usually accumulate to a certain thickness, and the moisture accumulated at the bottom requires a long processing time during drying. This results in very low efficiency in drying Antarctic krill, especially the Antarctic krill at the bottom is sometimes not fully dried, which interferes with subsequent production processes. Therefore, how to fully and efficiently dry Antarctic krill is an important issue that needs to be urgently solved in the production process of Antarctic krill oil. Utility Model Content

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0005] A rapid drying device for Antarctic krill comprises a drying cylinder, wherein a rotating shaft is rotatably connected inside the drying cylinder, a spiral blade is arranged on the rotating shaft, a feed port is arranged above one end of the drying cylinder, a discharge port is arranged at the other end of the drying cylinder, a plurality of water leakage holes are arranged in an array at the bottom of the drying cylinder, a connected water collecting trough is arranged below the water leakage holes, a drainage pipe is arranged on the water collecting trough, a steam interlayer is arranged on the outside of the drying cylinder in an area outside the water leakage holes, a plurality of air inlet pipes are arranged on the steam interlayer, and the air inlet pipes extend to the top of the drying cylinder after passing through the steam interlayer.
[0006] Furthermore, the longitudinal section of the water collecting trough is wide at the top and narrow at the bottom, and the drain pipe is located at the bottom of the water collecting trough.
[0007] Furthermore, an exhaust pipe is provided on the end of the water collecting trough close to the discharge port.
[0008] Furthermore, a plurality of main pipelines are arranged above the steam interlayer, each of the main pipelines is connected to a plurality of air inlet pipes, and an annular air duct is arranged between the plurality of main pipelines.
[0009] Furthermore, a filter screen is provided on the top of the water leakage hole.
[0010] Furthermore, the outside of the steam interlayer and the outside of the water collecting tank are both wrapped with a thermal insulation layer.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The structure of the utility model is that a rotating shaft is rotatably arranged inside the drying cylinder, and a spiral blade is arranged on the rotating shaft. After the Antarctic krill is poured into the drying cylinder from the feed port, the spiral blade is driven by the rotating shaft to rotate, thereby pushing the Antarctic krill to move toward the discharge port. During the movement, the spiral blade flips the Antarctic krill, so that the Antarctic krill at each position can contact the inner wall of the drying cylinder. At the same time, a steam interlayer is sleeved on the outside of the drying cylinder, and the side wall of the drying cylinder is steam-heated, so that the moisture on the surface of the Antarctic krill contacts the inner wall of the drying cylinder during the flipping process and is quickly evaporated, thereby greatly improving the efficiency of evaporation of moisture on the surface of the Antarctic krill, preventing the bottom from being incompletely dried, and ensuring the efficiency and uniformity of evaporation;

Such a structure allows the excess water in the Antarctic krill to pass through the water leakage holes and enter the water collecting tank and be separated from the Antarctic krill after entering the drying cylinder. This part of the water does not need to be evaporated and dried again, thereby reducing the evaporation and drying time to a certain extent. At the same time, a plurality of air inlet pipes are arranged on the outside of the steam interlayer, and the air inlet pipes extend to the top of the drying cylinder after passing through the steam interlayer. Such a structure allows the air entering from the air inlet pipe to be heated into hot air when passing through the steam interlayer, and then blown into the interior of the drying cylinder to contact the Antarctic krill, thereby quickly taking away the evaporated water vapor, thereby avoiding the water vapor from mixing with the Antarctic krill again and affecting the drying effect, further improving the efficiency of evaporation and drying of the Antarctic krill.

[0021] Reference Figure 1 and Figure 2The utility model is a rapid drying device for Antarctic krill, the main structure of which includes a drying cylinder 1, which is placed horizontally and is generally made of metal material with better heat conduction effect. The interior of the drying cylinder 1 is rotatably connected to a rotating shaft 2 through a bearing, and the rotating shaft 2 is driven to rotate by a motor. A spiral blade 3 is welded or bolted on the rotating shaft 2. A feed port 4 is provided above one end of the drying cylinder 1, and a discharge port 5 is provided at the other end of the drying cylinder 1. Antarctic krill enters the interior of the drying cylinder 1 from the feed port 4, and the rotating shaft 2 drives the spiral blade 3 rotates, the Antarctic krill moves toward the discharge port 5 under the drive of the spiral blade 3. During the movement, the Antarctic krill is flipped and moved by the spiral blade 3, so that the Antarctic krill at each position can contact the inner wall of the drying cylinder 1. The bottom of the drying cylinder 1 is arrayed with a plurality of leakage holes 6. The arrangement of the leakage holes 6 allows the excess water in the Antarctic krill entering the drying cylinder 1 to pass through the leakage holes 6 and be separated from the Antarctic krill. A connected water collecting tank 7 is provided below the leakage holes 6, and a drain pipe 8 is provided on the water collecting tank 7. Excess water is discharged from the drain pipe 8. The moisture enters the water collecting tank 7, so that this part of the moisture does not need to be dried by evaporation, which saves the drying time and greatly improves the evaporation efficiency. The area outside the drying cylinder 1 outside the water leakage hole 6 is sleeved with a steam interlayer 9, and the external steam enters the steam interlayer 9 to achieve steam heating treatment of the inner wall of the drying cylinder 1, so that the Antarctic krill at various positions that flip forward can contact the heated inner wall of the drying cylinder 1, so that the moisture therein is evaporated into water vapor and separated from the Antarctic krill, and there is no situation where the Antarctic krill at the bottom is not completely evaporated and dried, ensuring the uniformity and efficiency of the drying process. The steam interlayer 9 is provided with a plurality of air inlet pipes 10, and the external air enters from the air inlet pipes 10. The air inlet pipes 10 pass through the steam interlayer 9 and extend to the top of the drying cylinder 1. When the air passes through the steam interlayer 9, it is heated to hot air. After the hot air enters the interior of the drying cylinder 1, it quickly takes away the evaporated water vapor and discharges it from the discharge port 5, avoiding the evaporated water vapor from gathering in the drying cylinder 1 and contacting the Antarctic krill again to affect the overall drying effect, further improving the efficiency of evaporative drying.
[0022] Preferably, refer to Figure 3 The longitudinal section of the water collecting tank 7 is wide at the top and narrow at the bottom, and the drain pipe 8 is located at the bottom of the water collecting tank 7. This arrangement allows excess water to enter the water collecting tank 7 and concentrate at the bottom, so that it can be discharged more quickly and thoroughly from the drain pipe 8 at the bottom, avoiding the accumulation of water in the water collecting tank 7, and avoiding the accumulated water from evaporating due to excessive temperature and then passing through the leakage hole 6 again into the drying cylinder 1 above, thereby ensuring the speed of excess water discharge and reducing possible interference with the Antarctic krill drying process.
[0023] Preferably, an exhaust pipe 11 is provided at the end of the water collecting tank 7 near the discharge port 5. The exhaust pipe 11 generates suction by using components such as an external fan. The setting of the exhaust pipe 11 can quickly extract the steam formed after the evaporation of water that has not been discharged in time from the water collecting tank 7, thereby preventing the water vapor from entering the drying cylinder 1 again through the leakage hole 6, ensuring the timeliness of the discharge of excess water and reducing the interference of the separated excess water on the drying process.
[0024] Preferably, a plurality of main pipes 12 are provided above the steam interlayer 9, each of the main pipes 12 is connected to a plurality of air inlet pipes 10, and an annular air duct 13 is provided between the plurality of main pipes 12. External air enters each main pipe 12 from the annular air duct 13, and then is dispersed from the main pipe 12 to the plurality of air inlet pipes 10 and enters various positions on the top of the drying cylinder 1, so that the formed hot air is more evenly distributed in the drying cylinder 1, thereby improving the overall drying effect and uniformity.
[0025] Preferably, refer to Figure 4 A filter screen 14 is provided at the top of the water leakage hole 6. The setting of the filter screen 14 can prevent smaller Antarctic krill from falling from the water leakage hole 6, and only allow excess water to pass through, thereby reducing possible blockage or loss of Antarctic krill and ensuring the effect of separating excess water in Antarctic krill.
[0026] Preferably, the outside of the steam interlayer 9 and the outside of the water collecting tank 7 are wrapped with an insulation layer. Such a configuration can prevent the heat in the drying cylinder 1 from leaking out, thereby ensuring the efficiency of evaporating and drying the water in the Antarctic krill and ensuring the overall drying effect of the drying cylinder 1.
[0027] Working principle: The structure of the utility model is provided with a rotating shaft 2 which is rotatable inside the drying cylinder 1, and a spiral blade 3 is arranged on the rotating shaft 2. After the Antarctic krill is poured into the drying cylinder 1 from the feed port 4, the spiral blade 3 is driven by the rotating shaft 2 to rotate, thereby pushing the Antarctic krill to move toward the discharge port 5. During the movement, the spiral blade 3 flips the Antarctic krill, so that the Antarctic krill at each position can contact the inner wall of the drying cylinder 1. At the same time, a steam interlayer 9 is provided on the outside of the drying cylinder 1 to steam-heat the side wall of the drying cylinder 1, so that the moisture on the surface of the Antarctic krill contacts the inner wall of the drying cylinder 1 during the flipping process and is quickly evaporated, thereby greatly improving the efficiency of the evaporation of the moisture on the surface of the Antarctic krill, preventing the bottom from being incompletely dried, and ensuring the efficiency and uniformity of the evaporation; the array distribution at the bottom of the drying cylinder 1 There are multiple leaking holes 6, and a connected water collecting tank 7 is provided below the leaking holes 6. Such a structure allows the Antarctic krill to enter the drying cylinder 1. After the excess water in the Antarctic krill passes through the leaking holes 6, it enters the water collecting tank 7 and is separated from the Antarctic krill. This part of the water does not need to be evaporated and dried again, thereby reducing the evaporation and drying time to a certain extent. At the same time, multiple air inlet pipes 10 are provided on the outside of the steam interlayer 9. The air inlet pipe 10 passes through the steam interlayer 9 and extends to the top of the drying cylinder 1. Such a structure allows the air entering from the air inlet pipe 10 to be heated into hot air when passing through the steam interlayer 9, and then blown into the interior of the drying cylinder 1 to contact the Antarctic krill, thereby quickly taking away the evaporated water vapor, thereby avoiding the water vapor from mixing with the Antarctic krill again and affecting the drying effect, further improving the efficiency of evaporation and drying of the Antarctic krill.
