Description

Technical Field

[0001] The present invention belongs to the technical field of enzyme preparation equipment, and specifically relates to a device for preparing Pleurotus eryngii enzyme and a preparation method thereof. Background Art

[0002] King oyster mushroom (Pleurotus eryngii) is a highly nutritious edible fungus rich in dietary fiber, polysaccharides, protein, and various bioactive components, with potential benefits such as antioxidant, immune regulation, and intestinal health promotion. In recent years, enzyme products made from King oyster mushrooms have attracted considerable attention due to their promising applications in food, health supplements, and medicine. Currently, the production of King Oyster Mushroom enzymes primarily relies on traditional fermentation processes, which typically include raw material pretreatment (such as cleaning and crushing), fermentation, inactivation, filtration, and packaging. During the crushing process, the fiber density differences between the stipe and cap of King Oyster Mushrooms can easily lead to uneven crushing. This makes it difficult for microorganisms within the uncrushed King Oyster Mushroom pieces to reach the fermentation environment, resulting in reduced fermentation efficiency.

The fixed block is fixedly installed on one side of the screen, and a first spring is installed on the other side of the screen.

[0013] A method for preparing a Pleurotus eryngii enzyme preparation device comprises the following steps: S1: When working, first start the first motor to drive one of the first rotating shafts to rotate, the rotation of the first rotating shaft drives the rotation of the first gear, and the transmission of the first gear drives the other first rotating shaft to rotate, so that the two first rotating shafts drive the two crushing rollers to rotate; S2: The raw materials are then fed into the preparation box from the feed port and crushed by the crushing roller. The crushed raw materials fall to the top of the screen, are screened by the screen, and are discharged from the discharge port. S3: At the same time, the second motor is started to drive the reciprocating screw to rotate. The rotation of the reciprocating screw drives the first rack plate to move back and forth. The movement of the first rack plate drives the second gear to rotate. The rotation of the second gear drives the rotation of the second rotating shaft.

The rotation of the rotating disk drives the scraper to swing back and forth on the top of the screen, and scoops up the uncrushed raw materials on the top of the screen to the top of the crushing roller; S4: At the same time, the movement of the scraper drives the movement of the third gear. When the scraper moves to one side of the baffle, the third gear meshes with the second rack plate and rotates. The rotation of the third gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the top plate, causing the top plate to rotate and open to the side of the baffle. The material inside the scraper is discharged and crushed by the crushing roller again. S5: When the rotating disk rotates in the preparation box, the rotation of the rotating disk drives the rotation of the guide rod. When the guide rod moves to one side of the fixed block, it pushes the fixed block to one side. The movement of the fixed block drives the movement of the screen. At the same time, the elastic potential energy of the first spring is used to make the screen move back and forth, thereby improving the separation effect of the material and thus improving the preparation efficiency of the oyster mushroom enzyme.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a scraper assembly. When working, the second motor is started to drive the reciprocating screw to rotate. The rotation of the reciprocating screw drives the first rack plate to move back and forth. The movement of the first rack plate drives the second gear to rotate. The rotation of the second gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the rotating disk. The rotation of the rotating disk drives the scraper to swing back and forth on the top of the screen, and the raw materials that are not completely crushed on the top of the screen are picked up to the top of the crushing roller for secondary crushing, so as to ensure that the raw materials are completely crushed and the fermentation efficiency is ensured.

[0015] 2. The present invention is provided with a rotating assembly. When the scraper swings back and forth on the top of the screen, the movement of the scraper drives the movement of the third gear. When the scraper moves to one side of the baffle, the third gear engages with the second rack plate and rotates. The rotation of the third gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the top plate, so that the top plate rotates and opens to the side of the baffle, making it easier for the raw materials inside the scraper to be poured out.

[0016] 3. The present invention uses the reciprocating movement of the screen. When the rotating disk rotates in the preparation box, the rotation of the rotating disk drives the rotation of the guide rod. When the guide rod moves to one side of the fixed block, it pushes the fixed block to one side. The movement of the fixed block drives the movement of the screen. At the same time, the elastic potential energy of the first spring is used to make the screen move back and forth, further improving the separation effect of the materials, thereby improving the preparation efficiency of the oyster mushroom enzyme.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, in an embodiment of the present invention, a device for preparing oyster mushroom enzyme includes a preparation box 1, a feed port 2 is opened at the top of the preparation box 1, a discharge port 3 is opened at the bottom of the preparation box 1, two crushing rollers 4 are installed inside the preparation box 1, the ends of the two crushing rollers 4 are fixedly connected to a first rotating shaft 5, the outer walls of the two first rotating shafts 5 are fixedly installed with a first gear 6, the two first gears 6 are meshed and connected, and a first motor 7 is installed at one end of one of the first rotating shafts 5; A screen 8 is provided below the two first gears 6, and a scraping assembly is provided on the top of the screen 8; The scraper assembly includes a scraper 15 arranged on the top of the screen 8, and both sides of the top of the scraper 15 are rotatably connected to a top plate 16 through a rotating assembly; One side of the scraper 15 is fixedly connected to a rotating disk 9, which is rotatably mounted on the inner wall of the preparation box 1. One side of the rotating disk 9 is fixedly connected to a second rotating shaft 10, and a second gear 11 is fixedly mounted on the outer wall of the second rotating shaft 10. The bottom of the second gear 11 is meshed with a first rack plate 12, and the inner wall of the first rack plate 12 is threadedly connected to a reciprocating screw rod 13, and a second motor 14 is mounted on one end of the reciprocating screw rod 13.

[0020] During operation, the first motor 7 is first started to drive one of the first rotating shafts 5 to rotate. The rotation of the first rotating shaft 5 drives the rotation of the first gear 6, which drives the other first rotating shaft 5 to rotate through the transmission of the first gear 6, so that the two first rotating shafts 5 drive the two crushing rollers 4 to rotate; Then the raw material is put into the preparation box 1 from the feed port 2, and is crushed by the crushing roller 4. The crushed raw material falls to the top of the screen 8, is screened by the screen 8, and is discharged from the discharge port 3; At the same time, the second motor 14 is started to drive the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 drives the first rack plate 12 to move back and forth. The movement of the first rack plate 12 drives the second gear 11 to rotate. The rotation of the second gear 11 drives the rotation of the second rotating shaft 10. The rotation of the second rotating shaft 10 drives the rotation of the rotating disk 9. The rotation of the rotating disk 9 drives the scraper 15 to swing back and forth on the top of the screen 8, and the raw materials that are not completely crushed on the top of the screen 8 are picked up to the top of the crushing roller 4 for secondary crushing to ensure that the raw materials are completely crushed and the fermentation efficiency is ensured.

[0021] like Figure 7 and Figure 8 As shown, the inner walls of the scraper 15 and the top plate 16 are both provided with through holes 22 , and the through holes 22 are evenly distributed.

[0022] When the scraper 15 scoops up the unbroken raw materials on the top of the screen 8, the completely broken raw materials inside can be discharged through the through holes 22, and the unbroken raw materials stay inside the scraper 15 to avoid omission.

[0023] like Figure 2 As shown, two baffles 23 are provided below the feed port 2 , the two baffles 23 are symmetrically arranged, and both baffles 23 are fixedly installed inside the preparation box 1 .

[0024] When feeding, it prevents the raw materials from falling from the sides to the bottom without being crushed, which helps to ensure the crushing effect of the raw materials.

[0025] like Figure 2 、 Figure 3 and Figure 8As shown, the rotating assembly includes a third rotating shaft 17 fixedly mounted on the inner wall of the top plate 16, one end of the third rotating shaft 17 is fixedly connected to a third gear 18, the third gear 18 is slidably mounted on the inner wall of the preparation box 1, and a second rack plate 19 is fixedly mounted on the inner wall of the preparation box 1.

[0026] The second rack plate 19 is arranged above the baffle 23; When the scraper 15 swings back and forth on the top of the screen 8, the movement of the scraper 15 drives the movement of the third gear 18. When the scraper 15 moves to one side of the baffle 23, the third gear 18 engages with the second rack plate 19 and rotates. The rotation of the third gear 18 drives the rotation of the third rotating shaft 17. The rotation of the third rotating shaft 17 drives the rotation of the top plate 16, so that the top plate 16 rotates and opens to the side of the baffle 23, so that the raw materials inside the scraper 15 can be poured out.

[0027] like Figure 8 As shown, the third rotating shaft 17 is rotatably mounted on the inner wall of the scraper 15 , and a torsion spring 20 is installed between the third rotating shaft 17 and the scraper 15 .

[0028] The elastic potential energy of the torsion spring 20 always keeps the top plate 16 close to the scraper 15, reducing the possibility of the top plate 16 being opened due to the gravity of the material inside the scraper 15, thereby ensuring the material copying effect.

[0029] like Figure 2 and Figure 7 As shown, a rotating ring 21 is installed on the outer wall of the third rotating shaft 17 , and the rotating ring 21 is rotatably installed on the inner wall of the preparation box 1 .

[0030] The inner wall of the preparation box 1 is provided with a sliding groove for the third gear 18 to slide, and the rotating ring 21 is installed in the sliding groove to protect it and prevent materials from entering.

[0031] like Figure 7 and Figure 8 As shown, the third rotating shaft 17 is slidably connected to the rotating ring 21 .

[0032] like Figure 4 As shown, the inner wall of the screen 8 is evenly installed with protrusions 27 , each protrusion 27 is slidably connected to the screen 8 , and a second spring 28 is provided at the bottom of each protrusion 27 .

[0033] When the scraper 15 moves on the top of the screen 8, the bottom of the scraper 15 contacts the top of the protrusion 27 to press it into the screen 8, and after separation, the elastic potential energy is released by the second spring 28 to reset, so that the screen 8 and the scraper 15 have a certain elasticity, which helps to separate the completely crushed materials.

[0034] like Figure 4 、 Figure 5 and Figure 6As shown, the outer wall of the rotating disk 9 is evenly installed with guide rods 24 in a circular array, and a fixing block 25 is provided below the guide rod 24. The fixing block 25 is fixedly installed on one side of the screen 8, and a first spring 26 is installed on the other side of the screen 8.

[0035] When the rotating disk 9 rotates in the preparation box 1, the rotation of the rotating disk 9 drives the rotation of the guide rod 24. When the guide rod 24 moves to one side of the fixed block 25, the fixed block 25 is pushed to one side. The movement of the fixed block 25 drives the movement of the screen 8. At the same time, the elastic potential energy of the first spring 26 is cooperated to make the screen 8 move back and forth, further improving the separation effect of the material, thereby improving the preparation efficiency of the oyster mushroom enzyme.

[0036] A method for preparing a Pleurotus eryngii enzyme preparation device comprises the following steps: S1: When working, first start the first motor 7 to drive one of the first rotating shafts 5 to rotate. The rotation of the first rotating shaft 5 drives the rotation of the first gear 6, and the transmission of the first gear 6 drives the other first rotating shaft 5 to rotate, so that the two first rotating shafts 5 drive the two crushing rollers 4 to rotate; S2: The raw material is then fed into the preparation box 1 from the feed port 2 and crushed by the crushing roller 4. The crushed raw material falls to the top of the screen 8, is screened by the screen 8, and is discharged from the discharge port 3; S3: At the same time, the second motor 14 is started to drive the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 drives the first rack plate 12 to reciprocate. The movement of the first rack plate 12 drives the second gear 11 to rotate. The rotation of the second gear 11 drives the rotation of the second rotating shaft 10. The rotation of the second rotating shaft 10 drives the rotation of the rotating disk 9. The rotation of the rotating disk 9 drives the scraper 15 to swing back and forth on the top of the screen 8, and the uncrushed raw materials on the top of the screen 8 are picked up to the top of the crushing roller 4. S4: At the same time, the movement of the scraper 15 drives the movement of the third gear 18. When the scraper 15 moves to one side of the baffle 23, the third gear 18 engages with the second rack plate 19 and rotates. The rotation of the third gear 18 drives the rotation of the third rotating shaft 17. The rotation of the third rotating shaft 17 drives the rotation of the top plate 16, causing the top plate 16 to rotate and open to the side of the baffle 23. The material inside the scraper 15 is discharged and crushed again by the crushing roller 4; S5: When the rotating disk 9 rotates in the preparation box 1, the rotation of the rotating disk 9 drives the rotation of the guide rod 24. When the guide rod 24 moves to one side of the fixed block 25, the fixed block 25 is pushed to one side. The movement of the fixed block 25 drives the movement of the screen 8. At the same time, the elastic potential energy of the first spring 26 is cooperated to make the screen 8 move back and forth, thereby improving the separation effect of the material, thereby improving the preparation efficiency of the oyster mushroom enzyme.
