A production equipment for crayfish fermented feed

Abstract

This invention discloses a production equipment for fermented crayfish feed. The technical solution includes a fermentation tank body, with an anti-accumulation mechanism and a dispersion mechanism inside. The anti-accumulation mechanism includes a support component and multiple anti-accumulation components. The support component includes a reciprocating screw, one end of which is connected to a side wall inside the fermentation tank body via a bearing. The beneficial effects of this crayfish fermented feed production equipment are: the feed at the bottom is shoveled into the cavity through the storage box in the anti-accumulation mechanism and the dispersion mechanism. When it moves to the top, the feed is leaked out from the discharge port. The sieve plate sieves the feed falling from the discharge port, making the feed loose. At the same time, hot air is blown out through the air outlet, blowing the sieved feed. By repeatedly moving the feed up and down, the internal and external temperatures of the feed reach uniformity during fermentation, preventing the feed accumulating at the bottom from absorbing too much moisture, thereby reducing fermentation time and improving fermentation quality.

Description

Technical Field

[0001] This invention relates to the field of crayfish fermented feed technology, specifically to a production equipment for crayfish fermented feed. Background Technology

[0002] Crayfish are aquatic animals belonging to the class Crustacea, order Decapoda, and family Palaemonidae. Also known as red swamp crayfish, they resemble shrimp but have a hard shell. Adults are about 5.6-11.9 cm long, dark red in color, with a nearly black carapace. There is a wedge-shaped stripe on the dorsal side of the abdomen. Juveniles are uniformly gray, sometimes with black wavy lines. Their claws are narrow and long. The middle of the carapace is not divided by a mesh-like structure, and the carapace has obvious granules. The rostrum has lateral spines or notches at the tip. Fermented feed uses microorganisms and compound enzymes as fermentation agents to transform feed ingredients into a single biological fermented feed containing microbial cell protein, bioactive small peptides, amino acids, microbial active probiotics, and compound enzyme preparations. This product not only compensates for the amino acids that are easily lacking in conventional feeds but also rapidly converts the nutrients in other roughage ingredients, enhancing digestibility and absorption.

[0003] In the existing fermented crayfish feed, the internal and external temperatures of the feed differ during the fermentation process, resulting in inconsistent fermentation conditions and increasing the fermentation time required. Additionally, the feed tends to generate moisture during fermentation, with excessive moisture content in the bottom portion, which negatively impacts the fermentation quality. Summary of the Invention

[0004] Therefore, the present invention provides a production equipment for crayfish fermented feed, which solves the problem that during the fermentation process, the internal and external temperatures of the feed are different, the moisture content of the feed piled at the bottom is too high, which increases the fermentation time and affects the fermentation quality of the feed by means of an anti-piling mechanism and a dispersing mechanism.

The anti-accumulation component includes a fixed rod, and a storage box is fixedly sleeved on the outside of the fixed rod. The storage box has a cavity and a leakage port inside, and the cavity and the leakage port are connected.

[0007] The dispersing mechanism includes a sliding seat, which is sleeved on the outside of the reciprocating lead screw and connected to the reciprocating lead screw through a ball nut pair. A fixing plate is fixedly provided on the top of the sliding seat, and a support frame is fixedly connected to both ends of the fixing plate. A sieve plate is fixedly embedded inside the support frame. Both ends of the sliding seat have through holes, and air inlet pipes are inserted into both through holes. Multiple air outlet holes are provided on both sides of the two air inlet pipes, and a hot air pipe is fixedly connected to one end of the two air inlet pipes.

[0008] Preferably, the fermenter body has multiple supports fixedly installed at the bottom, a discharge port fixedly opened on one side of the fermenter body, a cover plate fixedly installed on the top of the fermenter body, and a feed port and a vent valve fixedly installed on the top of the cover plate.

[0009] Preferably, the support unit includes a support block, one end of which is fixedly connected to the inner wall of the fermenter body, and the other end of which has a ball groove with two balls inside.

[0010] Preferably, one end of the reciprocating screw extends out of the interior of the fermenter body and is connected to one side wall of the fermenter body via a bearing. A motor is provided at one end of the reciprocating screw extending out of the fermenter body. The output end of the motor is fixedly connected to the reciprocating screw. A motor frame is fixedly fitted outside the motor. The motor frame is fixedly connected to one side wall of the fermenter body.

[0011] Preferably, the second support plate is connected to the reciprocating lead screw via bearings, and the second support plate is connected to the second connecting plate via bearings.

[0012] Preferably, the first support plate is connected to the reciprocating lead screw via a bearing, and the first support plate is connected to the first connecting plate via a bearing.

[0013] Preferably, the second connecting plate and the first connecting plate are in contact with and rolled by the multiple balls, the second connecting plate is slidably connected to the second baffle, and the first connecting plate is slidably connected to the first baffle.

[0014] Preferably, both ends of the fixing rod are fixedly connected to the second connecting plate and the first connecting plate, respectively.

[0017] The embodiments of the present invention have the following advantages:

[0018] 1. The fixed rod in the anti-accumulation mechanism drives the storage box to make a circular motion around the reciprocating screw. When the storage box rotates past the bottom of the fermentation tank, it shovels the feed at the bottom into the cavity. When the storage box moves to the top, the feed inside the cavity leaks out from the leakage port, thereby preventing the feed at the bottom from accumulating and thus preventing the feed at the bottom from absorbing too much water.

[0019] 2. The feed falling from the feed outlet is sieved by the screen plate in the dispersing mechanism, making the feed loose and preventing the feed from condensing due to moisture. At the same time, hot air is blown into the air inlet pipe through the hot air pipe. The hot air inside the air inlet pipe is blown out through the air outlet, which blows the sieved feed and accelerates the evaporation of moisture in the sieved feed. By controlling the temperature of the blown hot air, the moisture content in the feed can be controlled.

[0020] 3. Through the anti-accumulation mechanism and the dispersion mechanism, the feed is moved up and down repeatedly, and the feed at the bottom is transported to the top and then automatically scattered down. This disperses and mixes the feed in areas with different temperature differences, so that the internal and external temperatures of the feed are unified during fermentation, thereby reducing fermentation time and improving fermentation quality.

Detailed Implementation

[0033] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] See attached document Figure 1-9 The present invention provides a production equipment for crayfish fermented feed, including a fermentation tank body 1, wherein the fermentation tank body 1 is provided with an anti-accumulation mechanism and a dispersion mechanism.

[0035] The anti-stacking mechanism includes a support assembly and multiple anti-stacking components. The support assembly includes a reciprocating screw 9, one end of which is connected to the inner side wall of the fermenter body 1 via a bearing. A second support plate 18 and a first support plate 13 are sleeved on the outside of the reciprocating screw 9. A second connecting plate 17 is sleeved on the outside of the second support plate 18, and a first connecting plate 12 is sleeved on the outside of the first support plate 13. A gear 10 is fixedly sleeved on the outside of the reciprocating screw 9, and a gear ring 11 is provided on the outside of the gear 10. The gear 10 meshes with the gear ring 11. Ring 11 is fixedly connected to connecting plate 12. Connecting plate 27 and connecting plate 12 are respectively provided with baffle 27 and baffle 28 on their inner sides. Baffle 27 and baffle 28 are both fixedly installed inside the fermentation tank body 1. Connecting plate 27 and connecting plate 12 are provided with multiple support units on their outer sides. The anti-accumulation component includes a fixing rod 14. A storage box 15 is fixedly sleeved on the outside of the fixing rod 14. A cavity 16 and a leakage port 32 are opened inside the storage box 15. The cavity 16 and the leakage port 32 are connected.

[0036] The dispersing mechanism includes a sliding seat 21, which is sleeved on the outside of the reciprocating screw 9 and connected to the reciprocating screw 9 through a ball nut pair. A fixing plate 22 is fixedly provided on the top of the sliding seat 21. A support frame 31 is fixedly connected to both ends of the fixing plate 22. A sieve plate 23 is fixedly embedded inside the support frame 31. Both ends of the sliding seat 21 have through holes 30. An air inlet pipe 20 is inserted into each of the two through holes 30. Multiple air outlet holes 29 are opened on both sides of the two air inlet pipes 20. A hot air pipe 19 is fixedly connected to one end of each of the two air inlet pipes 20.

[0037] In this implementation scheme, to achieve uniform internal and external temperatures during feed fermentation and prevent the accumulation of feed at the bottom from increasing its moisture content, the reciprocating screw 9 reverses, causing the gear 10 to drive the connecting plate 12 to rotate via the gear ring 11. The rotation of the connecting plate 12 causes the connecting plate 17 to rotate via multiple fixed rods 14. Simultaneously, the fixed rods 14 drive the storage box 15 to rotate around the reciprocating screw 9. When the storage box 15 rotates past the bottom of the fermentation tank body 1, it scoops the feed from the bottom into the cavity 16, thereby preventing the feed from accumulating at the bottom and absorbing excessive moisture. When the storage box 15 rotates to the top, the feed inside the cavity 16 falls through the discharge port 32. When the reciprocating screw 9 rotates, it drives the sliding seat 21 to move back and forth on the surface of the sieve plate 23. The movement of the sliding seat 21 drives the support frame 31 to move through the fixed plate 22. The support frame 31 drives the sieve plate 23 to sieve the feed falling from the feed outlet 32, making the feed loose and preventing the feed from condensing due to moisture. At the same time, hot air is blown into the air inlet pipe 20 through the hot air pipe 19. The hot air inside the air inlet pipe 20 is blown out through the air outlet 29, which blows the sieved feed and accelerates the evaporation of moisture in the sieved feed. By controlling the temperature of the blown hot air, the moisture content in the feed is controlled. At the same time, by repeatedly moving the feed up and down, the internal and external temperatures of the feed are made uniform during fermentation.

[0038] To achieve the rotation of the reciprocating screw 9, the device employs the following technical solution: multiple supports 2 are fixedly installed at the bottom of the fermentation tank body 1; a discharge port 6 is fixedly opened on one side of the fermentation tank body 1; a cover plate 3 is fixedly installed on the top of the fermentation tank body 1; a feed inlet 4 and a vent valve 5 are fixedly installed on the top of the cover plate 3; one end of the reciprocating screw 9 extends out of the interior of the fermentation tank body 1 and is connected to one side wall of the fermentation tank body 1 via a bearing; a motor 8 is installed at one end of the reciprocating screw 9 extending out of the fermentation tank body 1; the output end of the motor 8 is fixedly connected to the reciprocating screw 9; a motor frame 7 is fixedly fitted outside the motor 8; the motor frame 7 is fixedly connected to one side wall of the fermentation tank body 1; when the motor 8 is started, the motor 8 rotates, driving the reciprocating screw 9 to rotate.

[0039] To achieve stable rotation of connecting plate 2 17 and connecting plate 12, the device employs the following technical solution: The support unit includes a support block 24, one end of which is fixedly connected to the inner wall of the fermentation tank body 1, and the other end of which has a ball groove 25. Two balls 26 are located inside the ball groove 25. Connecting plate 2 17 and connecting plate 12 respectively contact and roll with the balls 26. Connecting plate 2 17 is slidably connected to baffle 2 27, and connecting plate 12 is slidably connected to baffle 28. When connecting plate 2 17 and connecting plate 12 rotate, they are supported by the cooperation of the support block 24, ball groove 25, and balls 26. Simultaneously, the balls 26 reduce the friction generated by the rotation of connecting plate 2 17 and connecting plate 12. Similarly, the sliding connection between connecting plate 2 17 and baffle 27, and between connecting plate 12 and baffle 28, blocks the feed and prevents leakage.

[0040] To prevent the sliding seat 21 from rotating when the reciprocating screw 9 rotates, the following technical solution is adopted: Support plate 28 is connected to the reciprocating screw 9 via bearings; support plate 28 is connected to connecting plate 27 via bearings; support plate 13 is connected to the reciprocating screw 9 via bearings; support plate 13 is connected to connecting plate 12 via bearings; the two ends of the fixing rod 14 are fixedly connected to connecting plate 27 and connecting plate 12 respectively; two air inlet pipes 20 are slidably connected to two through holes 30 respectively; one end of each air inlet pipe 20 is fixedly connected to support plate 13; the other end of each air inlet pipe 20 extends out of the fermenter body 1 and is fixedly connected to one side wall of the fermenter body 1; the other end of each air inlet pipe 20 penetrates support plate 28 and... The reciprocating screw 9 is fixedly connected to the second support plate 18. When the reciprocating screw 9 rotates, the bearing prevents the reciprocating screw 9 from driving the first support plate 13 and the second support plate 18 to rotate. When the first connecting plate 12 rotates and drives the second connecting plate 17 to rotate through the fixing rod 14, the bearing prevents the first connecting plate 12 and the second connecting plate 17 from driving the first support plate 13 and the second support plate 18 to rotate. Similarly, one end of the air inlet pipe 20 is fixed to one side wall of the fermenter body 1. The air inlet pipe 20 is fixed to the second support plate 18 and the first support plate 13, so that the air inlet pipe 20 will not rotate or move. When the reciprocating screw 9 rotates, it drives the sliding seat 21 to move through the ball nut pair. The sliding seat 21 is sleeved on the outside of the air inlet pipe 20 through the through hole 30, so as to prevent the sliding seat 21 from rotating and make the sliding seat 21 only move in a straight line.

[0041] The usage process of this invention is as follows: When using this invention, connect it to an external power source. Connect one end of the hot air pipe 19 to the hot air source. Start the motor 8. The rotation of the motor 8 drives the reciprocating screw 9 to rotate. The motor 8 controls the reciprocating screw 9 to reverse, causing the gear 10 to drive the connecting plate 12 to rotate through the gear ring 11. The rotation of the connecting plate 12 causes the connecting plate 27 to rotate through multiple fixed rods 14. When the connecting plate 27 rotates with the connecting plate 12, it is supported by the cooperation of the support block 24, the ball groove 25, and the ball 26. At the same time, the ball 26 reduces the friction generated by the rotation of the connecting plate 27 and the connecting plate 12. Similarly, the rotation of the connecting plate 27 is achieved through the cooperation of the support block 24, the ball groove 25, and the ball 26. The sliding connection between connecting plate 17 and baffle 27, and between connecting plate 12 and baffle 28, blocks the feed and prevents leakage. Simultaneously, the fixing rod 14 drives the storage box 15 to rotate around the reciprocating screw 9. When the storage box 15 rotates past the bottom of the fermentation tank body 1, it scoops the feed from the bottom into the cavity 16, preventing feed accumulation and excessive moisture absorption. When the storage box 15 rotates to the top, the feed inside the cavity 16 falls onto the surface of the sieve plate 23 through the discharge port 32. At the same time, the rotation of the reciprocating screw 9 drives the sliding seat 21 to move back and forth. The bearing prevents the reciprocating screw 9 from driving the support plate 13 and support plate 28 to rotate. When the connecting plate 12 rotates and drives the connecting plate 27 to rotate via the fixing rod 14, the bearing prevents the connecting plate 12 and connecting plate 27 from driving the support plate 13 and support plate 28 to rotate. Similarly, one end of the air inlet pipe 20 is fixed to one side wall of the fermenter body 1, and the air inlet pipe 20 is fixed to the support plate 28 and support plate 13, thus preventing the air inlet pipe 20 from rotating or moving. When the reciprocating screw 9 rotates, it drives the sliding seat 21 to move via the ball nut pair. The sliding seat 21 is sleeved on the outside of the air inlet pipe 20 through the through hole 30, thus preventing the sliding seat 21 from rotating. The movement of the sliding seat 21 allows it to move only in a straight line. The movement of the sliding seat 21 drives the support frame 31 to move via the fixed plate 22. The support frame 31 drives the sieve plate 23 to sieve the feed falling from the feed outlet 32, making the feed loose and preventing it from condensing due to moisture. At the same time, hot air is blown into the air inlet pipe 20 through the hot air pipe 19. The hot air inside the air inlet pipe 20 is blown out through the air outlet 29, which blows the sieved feed and accelerates the evaporation of moisture in the sieved feed. By controlling the temperature of the blown hot air, the moisture content in the feed is controlled. At the same time, by repeatedly moving the feed up and down, the internal and external temperatures of the feed are made uniform during fermentation.

[0042] The above are merely preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention are within the scope of protection claimed by the present invention.
