Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and more specifically to an automatic feeding device and method for producing high-fat Antarctic krill meal. Background Technology

[0002] Krill powder, a key raw material for extracting krill oil, has significant applications in nutrition, health, and medicine. Krill oil is rich in Omega-3 fatty acids, astaxanthin, and other bioactive components, possessing various physiological benefits such as anti-inflammatory, antioxidant, and lipid-regulating effects. Market demand for krill oil and its raw material, krill powder, is steadily increasing. In the krill powder production sector, automated feeding devices are crucial for ensuring efficient and stable production processes.

[0003] Existing automatic feeding devices and methods are diverse, mostly focusing on achieving stable material transport and basic crushing functions. Common feeding methods include screw conveyors and belt conveyors, which to some extent meet the feeding needs of conventional production environments. However, in the special scenario of Antarctic krill powder production, where Antarctic krill harvesting and processing often take place on ships in complex and variable operating environments, higher demands are placed on the adaptability, stability, and processing capacity of automatic feeding devices. Existing feeding devices face numerous problems when operating on ships. On the one hand, the ship's turbulence can easily cause material to shift and accumulate in the conveying section, affecting the uniformity of feeding. On the other hand, due to the high-fat nature of krill powder, which is prone to sticking and clogging due to its high oil content, the feeding device is easily blocked, causing the krill powder to stick and clump or be difficult to transport, affecting the krill powder conveying efficiency and the quality of the krill oil. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic feeding device and method for producing high-fat Antarctic krill powder, so as to solve the problem of easy clogging of the current automatic feeding device in the background art.

[0005] The present invention provides the following technical solution: an automatic feeding device for the production of high-fat Antarctic krill powder, comprising a machine compartment and a main screw, wherein the main screw is disposed in the inner cavity of the machine compartment, the inner cavity of the machine compartment has at least two barrels, and the barrels are provided with main screws with opposite rotation directions driven by a power device, the main screw is configured as a three-section structure, namely a conveying screw, a crushing screw, and a buffer screw connected in sequence, wherein the pitch of the crushing screw is smaller than the pitch of the buffer screw, and the pitch of the buffer screw is larger than the pitch of the conveying screw;

[0006] The partitions, numbering at least two, are disposed within the inner cavity of the main screw and sequentially installed at the connection points of the three screw sections. The partitions divide the barrel into three functional areas: a conveying section, a crushing section, and a buffer section. Shrimp powder is fed sequentially through these three areas.

[0007] A control plate is provided on one side of the partition to allow shrimp powder to pass through. The partition has a built-in control component, which controls the size of the opening of the control plate and adjusts the speed at which the shrimp powder passes through.

[0008] The crushing auxiliary component is located in the mounting hole on the outside of the main screw. The main screw is equipped with a motor-driven main propulsion plate. The movement of the main propulsion plate can push one end of the crushing auxiliary component out of the mounting hole and rotate with the main screw to clean the inside of the barrel.

[0009] Furthermore, a connecting groove for connecting to the main screw is provided on one side of the partition plate, and a powder dropping groove is provided below the connecting groove. Shrimp powder can enter the powder dropping groove through the connecting groove and enter the next processing section through the control plate. The control component includes a micro-pressure piston, and a pushing block is provided at the output end of the micro-pressure piston. A rack is fixedly connected to the pushing block, and a transmission gear is meshed at one end of the lower surface of the rack. A transmission frame is connected to the top of the control plate, and the contact surfaces of the transmission frame and the transmission gear mesh with each other.

[0010] Furthermore, a pressure hole is provided on one side of the partition, the micro-pressure piston is disposed in the pressure hole, the inner cavity of the powder dropping trough is configured with a slope inclined towards the control plate, and a groove is provided on the top of the transmission frame for the rack to pass through.

[0011] Furthermore, the crushing auxiliary component includes a limiting seat and a connecting seat. The limiting seat is installed in the middle of the mounting hole opened on the outside of the main screw, and the connecting seat is located at the end of the mounting hole. A displacement plate is provided on one side of the connecting seat, a locking plate is provided at one end of the displacement plate, and a scraper is provided on one side of the locking plate. Thrust blocks are provided on the corresponding surfaces of the main propulsion plate and the connecting seat, and the contact surfaces of the two thrust blocks are both set as mutually compatible inclined surfaces.

[0012] Furthermore, the outer edges of the corresponding surfaces of the linkage seat and the displacement plate are provided with a number of displacement blocks, and the two sets of displacement blocks are the same in number and interlaced with each other. The center of the limiting seat is provided with a groove that is compatible with the positioning plate.

[0013] Furthermore, a torsion spring is provided on the outer side of the linkage seat, one end of which is connected to the inner wall of the mounting hole. A rubber column is provided on one side of the linkage seat and is connected to the displacement plate through the rubber column.

[0014] Furthermore, the scraper is wedge-shaped, and the scrapers on the two main screws are arranged crosswise, that is, the scraper on one main screw corresponds to the screw groove of the other screw.

[0015] An automated feeding method for producing high-fat Antarctic krill meal includes the following steps:

[0016] S1: Turbulence condition perception and twin-screw adaptation: The ship attitude data is collected by a three-dimensional tilt sensor, and the main screw speed is adjusted according to the attitude data; At the same time, the krill powder fat content is adapted for pre-processing, and the fat content is detected by a near-infrared oil detector. The heating jacket of the conveying section is activated and the screw speed is adjusted according to the fat content.

[0017] S2: Material segmented conveying and crushing are coordinated. The power unit drives the two main screws to rotate in opposite directions. Krill powder enters the conveying section from the feed inlet and is conveyed quickly. After entering the crushing section, the particles are refined by the compression of the screw pitch and the shearing force of the twin screws. After crushing, the material enters the buffer section for temporary storage and is evenly conveyed to the downstream, forming a continuous process of "conveyor-crusher-buffer".

[0018] S3: Dynamic pressure control and anti-blockage. The pressure is detected in real time by the pressure sensor in the crushing section. The control components between the conveying section and the crushing section, and between the crushing section and the buffer section are adjusted according to the pressure value. The opening size of the control plate is changed to adjust the speed of material entering and exiting the crushing section.

[0019] S4: Emergency crushing treatment by scraper. When the pressure in the crushing section exceeds the set threshold, the controller triggers the scraper to automatically pop out and, with the rotation of the screw, use shearing force to crush the agglomerates. If the pressure continues to exceed the threshold, the twin screws will be driven to slow down and the quick-release cleaning door on the side of the barrel will be opened.

[0020] Furthermore, in step S1, the fat content adaptation pretreatment specifically involves activating the conveyor section heating jacket if the fat content of the krill powder exceeds the set value, and simultaneously adjusting the screw speed based on the speed adapted to the bumpy working conditions.

[0021] The technical effects and advantages of this invention are as follows:

[0022] This invention employs a twin-screw drive system, dividing the screws into a conveying section, a crushing section, and a buffer section, with differentiated screw pitches for each section. The main screw and the auxiliary screw rotate in opposite directions. During operation, the material passes quickly through the conveying section, and upon entering the crushing section, any agglomerated shrimp powder is compressed and crushed due to the reduced screw pitch. Furthermore, the small gap between the twin screws generates shearing force to refine the particles. This effectively solves the problem of uneven conveying and low efficiency caused by the easy adhesion and agglomeration of high-fat krill powder under turbulent conditions on a ship. It ensures stable conveying of krill powder and improves the quality of shrimp oil production.

[0023] In addition, due to the smaller pitch of the screw in the crushing section, the material is subjected to increased compression and shearing. At the same time, the high-fat krill powder itself is prone to sticking together. During the refining process of the krill powder, it is easy for the krill powder to adhere to the barrel and screw blades in the crushing section. After accumulating for a period of time, it is easy to cause blockage in the crushing section, which leads to an increase in pressure in the crushing section. When the crushing section is pressurized due to blockage, the speed regulation mechanism automatically adjusts the speed at which the krill powder enters the crushing section, reduces the amount of material accumulation in the crushing section, and enables the krill powder to be fully dispersed and crushed in the crushing section, further improving the stability of the conveying device.

[0024] Based on the above structure, scrapers are installed on the main screw and auxiliary screw shaft. When the pressure exceeds the threshold, the scrapers automatically pop out and crush the material as the screw rotates. This design complements the speed control mechanism in dealing with ship turbulence and blockage in the crushing section. It solves the problem that while the speed control mechanism can adjust the feed speed, it cannot effectively handle severe local adhesion or shrimp powder adhering to the screw. This further ensures that shrimp powder can still be fed efficiently and with high quality in the complex environment of cargo ship routes. Attached Figure Description

[0036] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Reference Figures 1-9 This invention provides an automatic feeding device for the production of high-fat Antarctic krill powder, comprising: 1. a machine compartment and 2. The main screw 2 is disposed in the inner cavity of the machine compartment 1. The inner cavity of the machine compartment 1 has at least two barrels, and the barrels are provided with main screws 2 rotating in opposite directions and driven by a power device 3. The main screw 2 is configured as a three-section structure, namely a conveying screw 21, a crushing screw 22, and a buffer screw 23 connected in sequence. The pitch of the crushing screw 22 is greater than the pitch of the buffer screw 23, and the pitch of the buffer screw 23 is greater than the pitch of the conveying screw 21.

[0038] At least two partitions 4 are installed in the inner cavity of the main screw 2 and are sequentially installed at the connection points of the conveying screw 21, the crushing screw 22, and the buffer screw 23. The partitions 4 divide the barrel into three functional areas: a conveying section, a crushing section, and a buffer section. The first section, the conveying screw 21, is located in the conveying section; the second section, the crushing screw 22, is located in the crushing section; and the third section, the buffer screw 23, is located in the buffer section. Shrimp powder is fed sequentially through the conveying section, the crushing section, and the buffer section.

[0039] The control plate 42 is opened on one side of the partition 4 for the shrimp powder to pass through. The partition 4 is also equipped with a control component 43, which controls the opening of the control plate 42 to regulate the speed at which the shrimp powder passes through the control plate 42.

[0040] The crushing auxiliary component 24 is a certain number of components and is installed in the mounting holes opened on the outside of the main screw 2. The main screw 2 has a main push plate 25 driven by a motor at one end of the crushing auxiliary component 24. By controlling the movement of the main push plate 25, the crushing auxiliary component 24 can be pushed so that one end of it is disengaged from the mounting hole. As the main screw 2 rotates, it cleans the inside of the barrel. Through the continuous rotation of the screw, the material is evenly conveyed from the feed port to the crushing section. The screw pitch in the conveying section is large to ensure that the material passes through quickly and reduce friction. After entering the crushing section, the screw pitch gradually decreases, and the material is compressed and crushed. The small gap between the screw and the barrel generates shearing force, refining the material particles. The medium screw pitch in the buffer section ensures uniform and continuous discharge. At the same time, pressure sensors installed in multiple sections of the barrel monitor the pressure in the crushing section in real time. When the pressure in the crushing section is too high, it indicates that there is a large accumulation of shrimp powder. The baffle 4 slows down the speed at which the shrimp powder enters the crushing section and increases the speed at which it exits, allowing the crushing section sufficient time to shear the shrimp powder and preventing the shrimp powder from sticking together due to the dense screw pitch. When blockage occurs in the barrel, the scraper on the surface of the main screw 2 automatically pops out and works with the rotation of the twin screws to crush and thoroughly clean the blocked shrimp powder, preventing the shrimp powder from sticking in the dead corners of the screw groove and ensuring efficient and stable feeding of shrimp powder.

[0041] Reference Figure 4 , Figure 5 , Figure 8A connecting groove 41 connected to the main screw 2 is provided on one side of the partition plate 4. A powder dropping groove 44 is provided below the connecting groove 41. Shrimp powder can enter the powder dropping groove 44 through the connecting groove 41 and enter the next processing section through the control plate 42. The control component 43 includes a micro-pressure piston 431. A push block 432 is provided at the output end of the micro-pressure piston 431. A rack 433 is fixedly connected to the push block 432. A transmission gear 434 is meshed at one end of the lower surface of the rack 433. A transmission frame 435 is connected to the top of the control plate 42. The contact surfaces of the transmission frame 435 and the transmission gear 434 mesh with each other. When the material in the crushing section continuously sticks and accumulates, forming a partial blockage, it will hinder the normal flow of gas in the crushing chamber, forming a closed space. As the motor continues to work, the pressure in the chamber will continue to accumulate. The plug is pushed under pressure, which in turn pushes the pusher block 432 to move via the micro-pressure piston 431, and pushes the rack 433 forward. The forward movement of the rack 433 drives the transmission gear 434, which meshes with it, to rotate. Since the contact surfaces of the transmission gear 434 and the transmission frame 435 mesh with each other, the transmission frame 435 moves downward. The downward movement of the transmission frame 435 pushes the control plate 42 downward, thereby reducing the passage space for shrimp powder. The speed at which shrimp powder enters the crushing section from the conveying section slows down. The partition 4 set in the crushing section and the buffer section is also equipped with a control component 43. When the pressure in the crushing section increases, the speed at which shrimp powder enters the buffer section from the crushing section increases, thereby continuously reducing the amount of shrimp powder in the crushing section, giving the shrimp powder sufficient processing time in the crushing section, and preventing the shrimp powder from continuously clogging in the crushing section.

[0042] Reference Figure 8 A pressure hole is provided on one side of the partition plate 4, and a micro-pressure piston 431 is set in the pressure hole. The inner cavity of the powder dropping trough 44 is set with a slope inclined towards the control plate 42. The top of the transmission frame 435 is provided with a groove for the rack 433 to pass through. When the pressure in the inner cavity of the main screw 2 increases, the pressure can be directly applied to the movement of the micro-pressure piston 431 through the pressure hole, thereby causing the micro-pressure piston 431 to move. The slope setting of the powder dropping trough 44 allows the shrimp powder to enter the powder dropping trough 44 and quickly pass through the control plate 42, avoiding the shrimp powder from clogging here.

[0043] Reference Figure 6 , Figure 7The crushing auxiliary component 24 includes a limiting seat 241 and a connecting seat 244. The limiting seat 241 is installed in the middle of the mounting hole opened on the outside of the main screw 2. The connecting seat 244 is located at the end of the mounting hole. A displacement plate 246 is provided on one side of the connecting seat 244. A locking plate 242 is provided at one end of the displacement plate 246. A scraper 243 is provided on one side of the locking plate 242. Thrust blocks 248 are provided on the corresponding surfaces of the main push plate 25 and the connecting seat 244. The contact surfaces of the two thrust blocks 248 are both set as mutually compatible inclined surfaces. When the pressure sensor in the barrel detects that the pressure exceeds a predetermined threshold, it indicates that the barrel... If a blockage occurs and the speed at which shrimp powder enters and exits the crushing chamber cannot be adjusted to improve the blockage, the main propulsion plate 25 is moved by the motor. The main propulsion plate 25 drives the thrust block 248 to move. After the two thrust blocks 248 collide, they push the linkage seat 244 to move towards the forward opening. The linkage seat 244 drives the positioning plate 242 to move and pass through the limit seat 241. The positioning plate 242 pushes the scraper 243, causing one end of it to protrude from the mounting hole. As the scraper 243 rotates, the impact generated by the rotation of the scraper 243 breaks up the hard agglomerates of shrimp powder in the gap between the screw blade and the barrel.

[0044] Reference Figure 6 , Figure 7 , Figure 8 The outer edges of the corresponding surfaces of the connecting seat 244 and the position plate 246 are provided with a number of position blocks 247. The two sets of position blocks 247 are the same in number and staggered. The center of the limiting seat 241 has a groove that matches the positioning plate 242. When the connecting seat 244 is pushed towards the mounting hole by the main push plate 25, the two sets of position blocks 247 collide and squeeze each other after the connecting seat 244 and the position plate 246 are close. This causes the position plate 246 to rotate slightly and drive the positioning plate 242 to rotate slightly. After the positioning plate 242 rotates, it matches the groove in the center of the limiting seat 241, so that the positioning plate 242 passes through the limiting seat 241 and successfully pushes the scraper 243 out of the mounting hole. The positioning of the positioning plate 242 and the limiting seat 241 prevents the scraper 243 from popping out due to the turbulence of the ship during normal operation of the feeding device, which would damage the screw or the inner wall of the barrel.

[0045] Reference Figure 7A torsion spring 249 is provided on the outer side of the linkage seat 244. One end of the torsion spring 249 is connected to the inner wall of the mounting hole. A rubber column 245 is provided on one side of the linkage seat 244 and is connected to the position plate 246 through the rubber column 245. When the linkage seat 244 moves and approaches the position plate 246, the rubber column 245 is compressed first, and the torsion spring 249 is stretched and changes shape. After the positioning plate 242 passes through the limit seat 241, the drive main push plate 25 pushes the linkage seat 244 again to make it contact the position plate 246. The positioning plate 242 rotates again. When the main push plate 25 retracts, the rubber column 245 and the torsion spring 249 lose pressure and rebound, giving the positioning plate 242 a retraction force. After the positioning plate 242 rotates again, it cannot pass through the limit seat 241, so that its position is fixed here. This can prevent the scraper 243 from protruding too much, which would cause damage to the barrel and the screw blade of the main screw 2.

[0046] Reference Figure 3 , Figure 6 The scraper 243 is wedge-shaped, and the scrapers 243 on the two main screws 2 are arranged in a cross pattern, that is, the scraper 243 on one main screw 2 corresponds to the screw groove of the other screw. When the shrimp powder clumps in the screw groove, the two main screws 2 can accurately spray and clean the shrimp powder in the corresponding screw groove when they rotate. The wedge-shaped surface of the scraper 243 can generate a vertical squeezing force on the shrimp powder, which is conducive to breaking up the clumps of shrimp powder.

[0047] Reference Figures 1-10 This invention provides an automated feeding method for producing high-fat Antarctic krill powder. After the device is started, the attitude data of the ship is collected by a three-dimensional tilt sensor, and the main screw speed is adjusted according to the attitude data. At the same time, the fat content of the krill powder is adapted for pre-processing. The fat content is detected by a near-infrared oil detector. The heating jacket of the conveying section is activated and the screw speed is adjusted according to the fat content to avoid material deviation due to bumps, ensure uniform feeding, and solve the problem of material accumulation in shipboard scenarios.

[0048] The power unit drives the two main screws to rotate in opposite directions, feeding the shrimp powder into the conveying section from the feed inlet. The large screw pitch enables the material to be conveyed quickly. After entering the crushing section, the small screw pitch compresses the material, and the fixed gap between the twin screws and the barrel generates shearing force to refine the material particles. The crushed material enters the buffer section, where the appropriate screw pitch temporarily stores the material and evenly conveys it to the downstream extraction equipment, forming a continuous and stable "conveyor-crusher-buffer" process.

[0049] The pressure sensor in the crushing section detects the pressure value in real time. When the pressure rises, the controller drives the control component between the conveying section and the crushing section to adjust the opening of the control plate, slowing down the speed at which the material enters the crushing section. At the same time, it drives the control component between the crushing section and the buffer section to increase the opening of the control plate, accelerating the speed at which the material is discharged from the crushing section. This ensures that the amount of material in the crushing section is stable, reduces the risk of blockage, and ensures that the particle size of the material is stable after crushing, meeting the requirements of raw material particle size for krill oil extraction.

[0050] When the pressure in the crushing section exceeds the set threshold due to localized agglomeration of materials, the controller triggers the scrapers on the twin screws, which generate mechanical impact force as the screws rotate, and together with the shearing force of the crushing section, break up the agglomerated shrimp powder lumps; if the pressure continues to exceed the threshold, the controller drives the twin screws to slow down, and at the same time opens the quick-release cleaning door on the side of the barrel to reduce the interruption time of shipboard production and ensure the continuity of the process;

[0051] Reference Figure 10 After initialization in step S1, the near-infrared grease detector detects the krill powder entering the buffer section. If the grease content of the krill powder exceeds the set value, the heating jacket of the conveying section is activated. At the same time, the screw speed is further adjusted based on the speed adapted to the bumpy working conditions to reduce the krill powder from sticking to the screw and the inner wall of the barrel. Because the krill powder is heated at the output end, the sticking to the screw and the barrel is reduced, and the scraper does not need to be activated frequently in the crushing section, thus reducing the scraper wear rate.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The present invention is not limited to the above embodiments; the embodiments and descriptions in the specification are merely illustrative of the principles of the invention.

An automated feeding method for producing high-fat Antarctic krill meal, characterized in that, An automatic feeding device for producing high-fat Antarctic krill meal according to any one of claims 1-7 includes the following steps: S1. Turbulence condition perception and twin-screw adaptation: The ship attitude data is collected by a three-dimensional tilt sensor, and the main screw speed is adjusted according to the attitude data; At the same time, the krill powder fat content is adapted for pre-processing, and the fat content is detected by a near-infrared oil detector. The heating jacket of the conveying section is activated and the screw speed is adjusted according to the fat content. S2. Material segmented conveying and crushing are coordinated. The power unit drives the two main screws to rotate in opposite directions. Krill powder enters the conveying section from the feed inlet and is conveyed quickly. After entering the crushing section, the particles are refined by the compression of the screw pitch and the shearing force of the twin screws. After crushing, the material enters the buffer section for temporary storage and is evenly conveyed to the downstream, forming a continuous process of "conveyor-crusher-buffer". S3: Dynamic pressure control and anti-blockage. The pressure is detected in real time by the pressure sensor in the crushing section. The control components between the conveying section and the crushing section, and between the crushing section and the buffer section are adjusted according to the pressure value. The opening size of the control plate is changed to adjust the speed of material entering and exiting the crushing section. S4: Emergency crushing treatment by scraper. When the pressure in the crushing section exceeds the set threshold, the controller triggers the scraper to automatically pop out and, with the rotation of the screw, use shearing force to crush the agglomerates. If the pressure continues to exceed the threshold, the twin screws will be driven to slow down and the quick-release cleaning door on the side of the barrel will be opened.

9. An automatic feeding method for producing high-fat Antarctic krill meal according to claim 8, characterized in that: In step S1, the fat content adaptation pretreatment specifically involves activating the conveyor section heating jacket if the fat content of the krill powder exceeds the set value, and further adjusting the screw speed based on the speed adapted to the bumpy working conditions.
