Technical Field

[0001] The present invention relates to the technical field of krill powder processing, and specifically to a rapid drying device and method for krill powder processing. Background Art

[0002] Antarctic krill is an important marine biological resource, and its processed product, Antarctic krill powder, has wide applications in fields such as feed, bait, and krill oil extraction. However, Antarctic krill contains a large amount of enzymes, which may cause self-dissolution of Antarctic krill. Therefore, it must be processed as soon as possible after capture, and a rapid drying device for krill powder processing has become one of the essential devices in Antarctic krill production and processing.

[0003] In the prior art, in the traditional krill drying method, generally, krill is poured into a drying device, then hot air is introduced into the device, and then the krill is continuously turned over by a stirring device to be dried.

Moreover, in this drying method, since the krill is piled up together, the drying efficiency is low. Summary of the Invention

[0014] As a preferred embodiment of the present invention, a threaded rod is threadedly connected to the outer side wall of the ventilation shell through a seventh square block; one end of the outer wall of the threaded rod is rotatably connected to an adjusting plate; the bottom end of the outer wall of the adjusting plate is in contact with the top end of the outer wall of the ventilation shell; the adjusting plate is matched with the ventilation part of the ventilation shell.

[0015] As a preferred embodiment of the present invention, a rapid drying method for krill powder processing includes the following steps:

[0016] Step 1: Krill or krill meal is placed into the feed shell. The heating device heats and dries the drying shell. The motor drives the rotating shaft to rotate, and the rotating shaft drives the threaded blades to rotate. When the krill or krill meal falls from the feed shell into the drying shell, it moves toward the square shell under the rotation of the threaded blades, and the krill or krill meal is dried while moving.

[0017] Step 2: When the krill or krill powder moves, the rotation of the rotating shaft drives the ninth rotating rod to rotate through the ninth sprocket and the ninth chain, and the ninth rotating rod drives a set of ninth bevel gears to rotate, and a set of ninth bevel gears drives a set of eighth bevel gears to rotate, so that the set of eighth bevel gears drives a set of eighth rotating rods and multiple sets of fan blades to rotate, thereby increasing air circulation;

[0018] Step 3: By rotating the threaded rod, since the threaded rod is threadedly connected to the seventh block, the threaded rod moves when it rotates, so that the movement of the threaded rod drives the adjustment plate to move, and the movement of the adjustment plate adjusts the ventilation of the ventilation shell, thereby adjusting the air circulation rate in the ventilation shell and the drying shell;

[0019] Step 4: When the krill or krill meal moves to the square shell through the threaded blades, the krill or krill meal falls from the connection between the square shell and the drying shell until it falls onto the filter plate. At this time, the rotating shaft drives the first rotating rod to rotate through the first sprocket and the first chain, so that the first rotating rod drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear and the rotating rod to rotate, so that the rotating rod drives a set of stirring plates to rotate, so that the krill or krill meal is secondary dried;

[0020] Step 5: When the stirring plate rotates, the rotation of the stirring plate drives the second rotating rod to rotate around the rotating rod, and the second rotating rod drives the third gear to rotate. Because a set of third gears are all meshed with the annular rack 1, when the third gear moves, the fixed and stationary annular rack 1 rotates while rotating, so that the rotation of the third gear drives the second rotating rod and the crushing blade to rotate. When the crushing blade rotates, it crushes and cuts the krill or krill meal, so that the krill or krill meal reaches a suitable size and can be filtered from the filter plate. After the krill or krill meal is filtered, the krill or krill meal will fall into the discharge space capsule body for vacuum discharge;

[0021] Step 6: When the crushing blade rotates, the crushing blade drives the third rotating rod and the fourth gear to rotate. Since the multiple sets of fourth gears are respectively engaged with a set of annular rack 2, when the fourth gear moves, it rotates while rotating through the fixed and stationary annular rack 2, thereby driving the third rotating rod and the auxiliary blade to rotate, so that the auxiliary blade cooperates with the crushing blade to crush the krill or krill powder;

[0022] Step 7: When the first rotating rod rotates, since the outer side wall of the first rotating rod and one end of the outer wall of the reciprocating rotating rod are both fixedly connected with fifth gears, and a pair of fifth gears mesh with each other, the first rotating rod drives the reciprocating rotating rod to rotate through the pair of fifth gears, the reciprocating rotating rod drives the connecting block to reciprocate, and the connecting block drives the filter plate to reciprocate;

[0023] Step 8: When the filter plate reciprocates, the reciprocating movement of the filter plate drives a pair of square plates to move, and the square plates drive the sixth rotating rod and the sixth gear to rotate. Since a pair of sixth gears respectively mesh with a pair of sixth racks, when the sixth gear moves, it rotates while moving through the sixth rack, the sixth gear drives the sixth rotating rod to rotate, the sixth rotating rod drives the circular shell, the circular rod and the vibrating ball to rotate, and the vibrating ball knocks on the bottom end of the outer wall of the filter plate to generate vibration;

[0024] Step 9: When the rotating shaft rotates, since one end of the outer wall of the seventh rotating rod outside the square shell and the outer side wall of the rotating shaft are both fixedly connected with fifth sprockets, and a pair of fifth sprockets are connected by a fifth chain, the rotating shaft drives the seventh rotating rod to rotate through the fifth sprockets and the fifth chain, the seventh rotating rod drives a group of metering plates to rotate. When krill or krill powder falls into the square shell, the krill or krill powder is evenly and quantitatively dropped onto the filter plate through the metering plates for secondary drying, crushing and cutting, and screening and filtering.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. When the stirring plate rotates, the rotation of the stirring plate drives the second rotating rod to rotate around the rotating rod, the second rotating rod drives the third gear to rotate. Since a group of third gears all mesh with the first annular rack, when the third gear moves, it rotates and rotates on its own while moving through the fixed first annular rack, the self-rotation of the third gear drives the second rotating rod and the crushing blade to rotate, and when the crushing blade rotates, it crushes and cuts the krill or krill powder, so that the krill or krill powder reaches a suitable size, and then is filtered from the filter plate, enabling the device to simultaneously perform drying, secondary drying, crushing, screening and filtering on the krill or krill powder, making the device not only more energy-saving but also more efficient.

[0027] 2. When the first rotating rod rotates, since the outer side wall of the first rotating rod and one end of the outer wall of the reciprocating rotating rod are both fixedly connected with fifth gears, and a pair of fifth gears mesh with each other, the first rotating rod drives the reciprocating rotating rod to rotate through the pair of fifth gears, the reciprocating rotating rod drives the connecting block to reciprocate, and the connecting block drives the filter plate to reciprocate, causing the reciprocating filter plate to produce a shaking or moving effect, and enabling the krill or krill powder on the filter plate to accelerate the screening efficiency under the shaking or moving effect of the filter plate.

[0039] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] Please refer to Figures 1-8 As shown, a rapid drying device for krill powder processing includes a base 1; the top end of the outer wall of the base 1 is fixedly connected with a drying shell 2 through a group of support columns; a heating device is provided inside the drying shell 2; the top end of the outer side wall of the drying shell 2 is fixedly connected with a feeding shell 3, and the feeding shell 3 is communicated with the drying shell 2; the top end of the outer wall of the base 1 is fixedly connected with a motor 4 through a support plate; a rotating shaft 5 is provided at the output end of the motor 4, and one end of the outer wall of the rotating shaft 5 extends into the drying shell 2; a threaded blade 6 is fixedly connected to the outer side wall of one end of the rotating shaft 5 located inside the drying shell 2; the bottom end of the outer side wall of the drying shell 2 is fixedly connected with a square shell 7, and the square shell 7 is communicated with the drying shell 2; the bottom end of the outer wall of the square shell 7 is fixedly connected with a discharge space capsule body 8; a knife gate valve is provided inside the discharge space capsule body 8. By putting krill or krill powder into the feeding shell 3, at this time, the heating device heats and dries the drying shell 2, the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the threaded blade 6 to rotate, so that when the krill or krill powder falls from the feeding shell 3 into the drying shell 2, it moves towards the square shell 7 under the rotation of the threaded blade 6, and the krill or krill powder is dried while moving. Because the krill or krill powder is dried part by part while moving, it is more evenly exposed to the heat source, thereby improving the drying efficiency. And during the moving process, the surface area of the krill is constantly changing, which is beneficial to the evaporation and discharge of water, so that the quality of the dried and processed krill is not only relatively uniform, but also high.

[0042] A filter plate 9 is arranged inside the square shell 7; an arc plate 10 is fixedly connected to the inner side wall of the square shell 7; the bottom end of the outer wall of the arc plate 10 is rotatably connected to a rotating rod 11; a group of stirring plates 12 are fixedly connected to the outer side wall of the rotating rod 11, and the stirring plates 12 are matched with the filter plate 9; a first bevel gear 13 is fixedly connected to the outer side wall of the rotating rod 11; one side of the outer wall of the square shell 7 is rotatably connected to a first rotating rod 14, and one end of the outer wall of the first rotating rod 14 extends into the square shell 7; a second bevel gear 15 is fixedly connected to the one end of the outer wall of the first rotating rod 14 located inside the square shell 7, and the second bevel gear 15 meshes with the first bevel gear 13; first sprockets 16 are fixedly connected to the one end of the outer wall of the first rotating rod 14 located outside the square shell 7 and the outer side wall of the rotating shaft 5, and a pair of first sprockets 16 are connected by a first chain 17. When the krill or krill powder moves to the position of the square shell 7 through the threaded blade 6, the krill or krill powder drops from the connection between the square shell 7 and the drying shell 2 until it drops onto the filter plate 9. At this time, the rotating shaft 5 drives the first rotating rod 14 to rotate through the first sprocket 16 and the first chain 17, so that the first rotating rod 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the first bevel gear 13 and the rotating rod 11 to rotate, the rotating rod 11 drives a group of stirring plates 12 to rotate, and the krill or krill powder is secondarily dried, so that the krill or krill powder can be dried more thoroughly, and the two drying methods are used to dry the krill or krill powder, making the quality of the dried krill or krill powder better.

[0043] A square through groove 18 is formed on one side of the outer wall of the stirring plate 12; the bottom end of the inner wall of the square through groove 18 is rotatably connected to a second rotating rod 19, and a group of crushing blades 20 are fixedly connected to the outer side wall of the second rotating rod 19; third gears 21 are fixedly connected to the outer side walls of a group of second rotating rods 19; a first annular rack 22 is fixedly connected to the opposite sides of the inner wall of the square shell 7 through a pair of first square plates; a group of third gears 21 all mesh with the first annular rack 22. When the stirring plate 12 rotates, the rotation of the stirring plate 12 drives the second rotating rod 19 to rotate around the rotating rod 11, and the second rotating rod 19 drives the third gear 21 to rotate. Since a group of third gears 21 all mesh with the first annular rack 22, when the third gear 21 moves, through the fixed and stationary first annular rack 22, it rotates and rotates itself, so that the self-rotation of the third gear 21 drives the second rotating rod 19 and the crushing blade 20 to rotate, and the crushing blade 20 rotates to crush and cut the krill or krill powder, so that the krill or krill powder reaches a suitable size, and then is filtered from the filter plate 9, enabling the device to simultaneously perform drying, secondary drying, crushing, screening and filtering on the krill or krill powder, making the device not only more energy-saving but also more efficient.

[0044] One side of the outer wall of the square shell 7 is rotatably connected to a seventh rotating rod 37, and one end of the outer wall of the seventh rotating rod 37 extends into the square shell 7; a group of metering plates 38 are fixedly connected to the outer side wall of one end of the seventh rotating rod 37 located inside the square shell 7, and the metering plates 38 match the square shell 7; fifth sprockets 39 are fixedly connected to one end of the outer wall of the seventh rotating rod 37 located outside the square shell 7 and the outer side wall of the rotating shaft 5, and a pair of fifth sprockets 39 are connected by a fifth chain 40. When the rotating shaft 5 rotates, since fifth sprockets 39 are fixedly connected to one end of the outer wall of the seventh rotating rod 37 located outside the square shell 7 and the outer side wall of the rotating shaft 5, and a pair of fifth sprockets 39 are connected by a fifth chain 40, the rotating shaft 5 drives the seventh rotating rod 37 to rotate through the fifth sprockets 39 and the fifth chain 40, the seventh rotating rod 37 drives a group of metering plates 38 to rotate. When krill or krill powder falls into the square shell 7, the metering plates 38 enable the krill or krill powder to be quantitatively dropped onto the filter plate 9 for secondary drying, crushing and cutting, and screening and filtering. Through quantitative feeding, the secondary drying, crushing and cutting, and screening and filtering of krill or krill powder are not easily affected by excessive krill or krill powder, and the efficiency and effect of drying, crushing, or screening are improved, making the effect of secondary drying, crushing and cutting, and screening and filtering of krill or krill powder better.

When the first rotating rod 14 rotates, since fifth gears 29 are fixedly connected to the outer side wall of the first rotating rod 14 and one end of the outer wall of the reciprocating rotating rod 28, and a pair of fifth gears 29 mesh with each other, the first rotating rod 14 drives the reciprocating rotating rod 28 to rotate through a pair of fifth gears 29, the reciprocating rotating rod 28 drives the connecting block 27 to reciprocate, the connecting block 27 drives the filter plate 9 to reciprocate, and the reciprocating filter plate 9 produces a shaking or moving effect, enabling the krill or krill powder on the filter plate 9 to accelerate the screening efficiency under the shaking or moving effect of the filter plate 9.

[0046] On one side of the inner wall of the square through groove 18, a second square plate is fixedly connected with an annular rack two 23; the outer wall top of the crushing blade 20 is rotationally connected with a third rotating rod 53; a group of auxiliary blades 24 are fixedly connected to the outer side wall of the third rotating rod 53; the outer wall top of the third rotating rod 53 is fixedly connected with a fourth gear 25; multiple groups of fourth gears 25 are respectively meshed with a group of annular racks two 23. When the crushing blade 20 rotates, the crushing blade 20 drives the third rotating rod 53 and the fourth gear 25 to rotate. Because multiple groups of fourth gears 25 are respectively meshed with a group of annular racks two 23, when the fourth gear 25 moves, through the fixed and stationary annular rack two 23, it rotates while rotating itself, thereby driving the third rotating rod 53 and the auxiliary blade 24 to rotate, enabling the auxiliary blade 24 to cooperate with the crushing blade 20 to crush krill or krill powder, and further improving the crushing efficiency and effect of the device.

[0047] On the opposite sides of the inner wall of the square shell 7, a sixth rack 30 is fixedly connected; a square plate 31 is fixedly connected to the outer wall bottom of the filter plate 9; on the opposite sides of the outer wall of a pair of square plates 31, a sixth rotating rod 32 is rotationally connected; a sixth gear 33 is fixedly connected to the outer side wall of a pair of sixth rotating rods 32, and a pair of sixth gears 33 are respectively meshed with a pair of sixth racks 30; a group of circular shells 34 are fixedly connected to the outer side wall of the sixth rotating rod 32; on one side of the inner wall of the circular shell 34, a circular rod 35 is fixedly connected through a first spring, and the outer side wall of the circular rod 35 is slidably connected to the inner side wall of the circular shell 34; one end of the outer wall of the circular rod 35 is fixedly connected with a vibration ball 36, and the vibration ball 36 is matched with the filter plate 9. When the filter plate 9 reciprocates, the reciprocating movement of the filter plate 9 drives a pair of square plates 31 to move, and the square plates 31 drive the sixth rotating rod 32 and the sixth gear 33 to rotate. Because a pair of sixth gears 33 are respectively meshed with a pair of sixth racks 30, when the sixth gear 33 moves, it moves and rotates through the sixth rack 30, enabling the sixth gear 33 to drive the sixth rotating rod 32 to rotate, enabling the sixth rotating rod 32 to drive the circular shell 34, the circular rod 35 and the vibration ball 36 to rotate, enabling the vibration ball 36 to strike the outer wall bottom of the filter plate 9 to generate vibration, and further accelerating the screening efficiency of krill powder by the vibration force.

When the krill or krill powder moves, the rotation of the rotating shaft 5 drives the ninth rotating rod 46 to rotate through the ninth sprockets 48 and the ninth chain 49. The ninth rotating rod 46 drives the group of ninth bevel gears 47 to rotate, and the group of ninth bevel gears 47 drive the group of eighth bevel gears 45 to rotate, so that the group of eighth bevel gears drive the group of eighth rotating rods 52 and the multiple groups of fan blades 44 to rotate, increasing the air circulation. Since the air circulation can accelerate the heat transfer on the surface of the material, the drying rate is improved, and the drying efficiency of the krill or krill powder is better.

[0050] A threaded rod 50 is connected to the outer side wall of the ventilation case 41 through a seventh square block; one end of the outer wall of the threaded rod 50 is rotatably connected with an adjusting plate 51; the bottom end of the outer wall of the adjusting plate 51 is in contact with the top end of the outer wall of the ventilation case 41; the adjusting plate 51 matches the ventilation part of the ventilation case 41. By rotating the threaded rod 50, since the threaded rod 50 is threadedly connected to the seventh square block, the threaded rod 50 moves when it rotates, and the movement of the threaded rod 50 drives the adjusting plate 51 to move, so that the movement of the adjusting plate 51 adjusts the ventilation part of the ventilation case 41, thereby adjusting the air circulation rate in the ventilation case 41 and the drying case 2. Since the lipids in the krill powder are easily oxidized under the action of high temperature and oxygen, but appropriate air circulation can take away part of the oxygen and reduce the oxygen concentration on the surface of the material, thus slowing down the oxidation process to a certain extent. The device can adjust the air circulation rate according to the situation when drying the krill or krill powder, so that appropriate air circulation can not only improve the drying efficiency and effect of the krill or krill powder, but also not easily affect the drying quality of the krill or krill powder.

[0051] When the present invention is in use, krill or krill powder is put into the feeding shell 3. At this time, the heating device heats and dries the drying shell 2. The motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the threaded blade 6 to rotate. When the krill or krill powder falls from the feeding shell 3 into the drying shell 2, it moves towards the square shell 7 under the rotation of the threaded blade 6, and the krill or krill powder is dried while moving. Since the krill or krill powder moves and dries part by part, it is more evenly exposed to the heat source, thereby improving the drying efficiency. During the moving process, the surface area of the krill continuously changes, which is conducive to the evaporation and discharge of moisture, so that the quality of the dried and processed krill is not only relatively uniform but also high.

[0052] When the krill or krill powder moves, the rotation of the rotating shaft 5 drives the ninth rotating rod 46 to rotate through the ninth sprocket 48 and the ninth chain 49. The ninth rotating rod 46 drives a set of ninth bevel gears 47 to rotate, and a set of ninth bevel gears 47 drives a set of eighth bevel gears 45 to rotate, so that a set of eighth bevel gears drives a set of eighth rotating rods 52 and multiple sets of fan blades 44 to rotate, increasing air circulation. Since air circulation can accelerate the heat transfer on the surface of the material, the drying rate is thus increased, and the drying efficiency of the krill or krill powder is better.

[0053] By rotating the threaded rod 50, since the threaded rod 50 is threadedly connected to the seventh square block, the threaded rod 50 moves when it rotates. The movement of the threaded rod 50 drives the adjusting plate 51 to move, and the movement of the adjusting plate 51 adjusts the ventilation area of the ventilation shell 41, thereby adjusting the air circulation rate in the ventilation shell 41 and the drying shell 2. Since the lipids in the krill powder are easily oxidized under the action of high temperature and oxygen, but appropriate air circulation can take away part of the oxygen and reduce the oxygen concentration on the surface of the material, thus slowing down the oxidation process to a certain extent. The device can adjust the air circulation rate according to the situation when the krill or krill powder is dried, so that appropriate air circulation can not only improve the drying efficiency and effect of the krill or krill powder, but also not easily affect the drying quality of the krill or krill powder.

[0054] When the krill or krill powder moves to the square shell 7 through the threaded blade 6, the krill or krill powder falls from the connection between the square shell 7 and the drying shell 2 until it falls onto the filter plate 9. At this time, the rotating shaft 5 drives the first rotating rod 14 to rotate through the first sprocket 16 and the first chain 17, so that the first rotating rod 14 drives the second bevel gear 15 to rotate, and the second bevel gear 15 drives the first bevel gear 13 and the rotating rod 11 to rotate, and the rotating rod 11 drives a set of stirring plates 12 to rotate, enabling the krill or krill powder to be dried for the second time, so that the krill or krill powder can be dried more thoroughly, and also drying the krill or krill powder by two drying methods, making the quality of the dried krill or krill powder better.

[0055] When the stirring plate 12 rotates, the rotation of the stirring plate 12 drives the second rotating rod 19 to rotate around the rotating rod 11. The second rotating rod 19 drives the third gear 21 to rotate. Since a set of third gears 21 are all meshed with the first annular rack 22, when the third gear 21 moves, through the fixed and stationary first annular rack 22, it rotates and self-rotates at the same time, so that the self-rotation of the third gear 21 drives the second rotating rod 19 and the crushing blade 20 to rotate. When the crushing blade 20 rotates, it crushes and cuts the krill or krill powder, so that the krill or krill powder reaches a suitable size, and then is filtered through the filter plate 9, enabling the device to simultaneously dry, secondarily dry, crush, screen and filter the krill or krill powder, making the device not only more energy-saving but also more efficient.

[0056] When the rotating shaft 5 rotates, since a fifth sprocket 39 is fixedly connected to one end of the outer wall of the seventh rotating rod 37 outside the square shell 7 and the outer side wall of the rotating shaft 5, and a pair of fifth sprockets 39 are connected by a fifth chain 40, the rotating shaft 5 drives the seventh rotating rod 37 to rotate through the fifth sprocket 39 and the fifth chain 40. The seventh rotating rod 37 drives a set of metering plates 38 to rotate. When the krill or krill powder falls into the square shell 7, through the metering plates 38, the krill or krill powder is quantitatively dropped onto the filter plate 9 for secondary drying, crushing and cutting, and screening and filtering. Through quantitative feeding, when the krill or krill powder is subjected to secondary drying, crushing and cutting, and screening and filtering, it is not easy to affect the efficiency and effect of drying, crushing or screening due to too much krill or krill powder, making the effect of secondary drying, crushing and cutting, and screening and filtering of the krill or krill powder better.

[0057] When the crushing blade 20 rotates, the crushing blade 20 drives the third rotating rod 53 and the fourth gear 25 to rotate. Since multiple sets of fourth gears 25 are respectively meshed with a set of second annular racks 23, when the fourth gear 25 moves, through the fixed and stationary second annular racks 23, it rotates and self-rotates at the same time, thereby driving the third rotating rod 53 and the auxiliary blade 24 to rotate, and the auxiliary blade 24 cooperates with the crushing blade 20 to crush the krill or krill powder, so that the crushing efficiency and effect of the device are further improved.

[0058] When the first rotating rod 14 rotates, since a fifth gear 29 is fixedly connected to the outer side wall of the first rotating rod 14 and one end of the outer wall of the reciprocating rotating rod 28, and a pair of fifth gears 29 are meshed with each other, the first rotating rod 14 drives the reciprocating rotating rod 28 to rotate through a pair of fifth gears 29. The reciprocating rotating rod 28 drives the connecting block 27 to reciprocate, and the connecting block 27 drives the filter plate 9 to reciprocate, so that the reciprocating filter plate 9 produces a shaking or moving effect, and the krill or krill powder on the filter plate 9 can accelerate the screening efficiency of the krill powder under the shaking or moving effect of the filter plate 9.

[0059] When the filter plate 9 reciprocates, the reciprocating motion of the filter plate 9 drives a pair of square plates 31 to move. The square plates 31 drive the sixth rotating rod 32 and the sixth gear 33 to rotate. Since a pair of sixth gears 33 are respectively engaged with a pair of sixth racks 30, when the sixth gears 33 move, they rotate while moving through the sixth racks 30, causing the sixth gears 33 to drive the sixth rotating rod 32 to rotate. The sixth rotating rod 32 drives the circular shell 34, the circular rod 35 and the vibrating ball 36 to rotate, causing the vibrating ball 36 to strike the bottom end of the outer wall of the filter plate 9 to generate vibration, and further accelerating the screening efficiency of krill powder by the vibration force.

[0060] After the krill powder is pulverized, screened and filtered, the krill or krill powder will fall into the discharge space capsule body 8 for vacuum discharging.
