[0002] As an important part of traditional agriculture, the quality of silkworm feed directly affects the growth and development of silkworms and the silk production. At present, traditional silkworm feeds mainly consist of mulberry leaf powder, supplemented with nutrients such as protein powder and starch. However, such feeds are prone to mildew during storage due to the influence of environmental humidity, and at the same time, harmful gases such as ammonia and ethylene are produced due to the action of microorganisms, resulting in a shortened shelf life of the feed. In addition, although the polyphenolic substances in mulberry leaves have antioxidant functions, they are easily oxidized and degraded during processing and storage, limiting the exertion of their long-term effects. Summary of the Invention

[0030] In order to make the purpose and advantages of the present invention more clear, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific scope of protection claimed by the present invention.

[0031] Embodiment 1:

[0032] A method for preparing a titanium dioxide-added silkworm feed includes the following steps:

[0033] Step 1. Preparation of titanium dioxide microcapsules: The preparation of titanium dioxide microcapsules is carried out by using the sodium alginate-chitosan microcapsule encapsulation technology. Specifically, food-grade nano-titanium dioxide (particle size 50 - 100 nm) is dispersed in the mulberry leaf polyphenol extract in a ratio of 1:10 to form a uniform suspension, and the suspension is encapsulated in a sodium alginate-chitosan double-layer microcapsule by the ion cross-linking method, and the particle size of the microcapsule is controlled to be 200 - 300 μm.

[0034] By setting the titanium dioxide microcapsules, the direct contact between TiO2 and the silkworm intestine can be reduced, the potential toxicity risk can be lowered, the mulberry leaf polyphenols can be slowly released, and the antioxidant function can be enhanced.

[0035] Step 2, Material mixing: Mix mulberry leaf powder, soy protein powder, corn starch, compound vitamin / mineral premix, and titanium dioxide microcapsules in a weight ratio of 6:2:1:0.5:0.5 to form a mixed raw material;

[0036] Specifically, Step 2 includes the following steps:

[0037] Step 201: Put mulberry leaf powder, soy protein powder, corn starch, and compound vitamin / mineral premix into a three-dimensional motion mixer in proportion and mix for 20 - 30 minutes.

[0038] Step 202: Add microencapsulated titanium dioxide additive and continue to mix for 10 minutes until uniform to form a mixed raw material.

[0039] Herein, the compound vitamin / mineral premix includes vitamin A (5000 IU / kg), vitamin D3 (1000 IU / kg), vitamin E (50 mg / kg), iron (80 mg / kg), zinc (60 mg / kg), selenium (0.3 mg / kg), and the carrier is wheat bran.

[0040] Step 3, Granulation: Use a granulator to granulate the mixed raw material to form cylindrical feed pellets.

[0041] Step 4, Photoactivation treatment: Irradiate the feed pellets with ultraviolet light (365 nm) for 10 minutes to activate the photocatalytic performance of TiO2 on the surface of the titanium dioxide microcapsules, and use the photocatalytic property of TiO2 to assist in decomposing harmful gases (such as ethylene and ammonia) generated during feed storage to extend the shelf life.

[0042] Step 5, Low-temperature drying: Dry the feed pellets with hot air at 45°C until the water content ≤ 12% to form titanium dioxide silkworm feed.

[0043] In summary, through the setting of titanium dioxide microcapsules, this technical solution can reduce the direct contact of TiO2 with the silkworm intestine, reduce the potential toxicity risk, slow-release mulberry leaf polyphenols, enhance the antioxidant function, use the photocatalytic property of TiO2 to assist in decomposing harmful gases (such as ethylene and ammonia) generated during feed storage, and extend the shelf life.

[0044] This technical solution selects 500 healthy silkworm larvae, divides them into an experimental group (adding 0.5% microencapsulated TiO2) and a control group (without adding TiO2), and raises them for 7 days in the same environment.

[0045] The survival rate of the experimental group is 97.2%, and that of the control group is 96.8%; anatomical detection shows that the intestinal mucosa of the silkworms in the experimental group is intact, without signs of inflammation or apoptosis, proving that microencapsulated TiO2 has no significant toxicity within the safe addition amount;

[0046] Verified by acute toxicity experiments (refer to GB / T 31270-2014), when the addition amount of microencapsulated TiO2 ≤ 0.5%, the survival rate of silkworm larvae > 95%, and no abnormal pathological changes were found in the intestinal tissue sections.

[0047] Example Two:

[0048] As Figures 1 - 8 shown, in this example, on the basis of Example One, the structure of the granulator is disclosed. The granulator includes a granulator housing 1. Inside the granulator housing 1, two juxtaposed cylindrical rotating shafts 6 are rotatably connected. A number of shaping grooves are provided on the outer sides of the two cylindrical rotating shafts 6. The shaping grooves on the outer sides of the two cylindrical rotating shafts 6 are opposite to each other. During the rotation of the cylindrical rotating shafts 6, the mixed raw materials can be extruded and shaped through the shaping grooves, and the mixed raw materials are extruded into cylindrical particles to form cylindrical feed particles;

[0049] In order to drive the cylindrical rotating shafts 6 to rotate, a rotary drive mechanism 11 that is drivingly connected to the cylindrical rotating shafts 6 is fixedly connected to the outside of the granulator housing 1. Through the rotary drive mechanism 11, the two cylindrical rotating shafts 6 can be driven to rotate in opposite directions. The rotary drive mechanism 11 can be two stepper motors, and the two stepper motors are respectively drivingly connected to the two cylindrical rotating shafts 6. The rotary drive mechanism 11 can also be a single stepper motor. The stepper motor is drivingly connected to the two cylindrical rotating shafts 6 through a gear transmission group, and the two cylindrical rotating shafts 6 can be driven to rotate in opposite directions.

[0050] In order to be able to guide the mixed raw materials between the two cylindrical rotating shafts 6, two feed hoppers 2 are fixedly connected to the upper side of the granulator housing 1. Guide plates 3 are installed on both sides inside the granulator housing 1. The sides of the two guide plates 3 close to each other are inclined downward, so that the mixed raw materials can be guided between the two cylindrical rotating shafts 6 through the feed hoppers 2 and the guide plates 3 to receive the granulation work of the two cylindrical rotating shafts 6.

[0051] The guide plates 3 can be fixedly connected inside the granulator housing 1 or rotatably connected inside the granulator housing 1. When the guide plates 3 are rotatably connected inside the granulator housing 1, round rods are fixedly connected to the sides of the two guide plates 3 away from each other. The round rods are rotatably connected to the granulator housing 1. A first motor 4 is fixedly connected to the outside of the granulator housing 1. The output end of the first motor 4 is fixedly connected with a cam located below the guide plates 3. By starting the first motor 4 to drive the cam to rotate, the guide plates 3 can be vibrated, and the mixed raw materials on the upper side of the guide plates 3 can fall more evenly between the two cylindrical rotating shafts 6 through the vibration.

[0052] Inside the granulator housing 1, an inclined plate 10 is fixedly connected below the two cylindrical rotating shafts 6. At the lower end of the front side of the granulator housing 1, a feed outlet 12 is provided. One side of the inclined plate 10 extends to the outside of the granulator housing 1 through the feed outlet 12, and the end of the inclined plate 10 located outside the granulator housing 1 is inclined downward, so that the formed cylindrical feed pellets can slide along the inclined plate 10 and slide out of the feed outlet 12 to complete the discharging.

[0053] The core of this technical solution lies in that the size of the shaping groove is adjustable, so that cylindrical feed pellets of different sizes can be manufactured according to requirements.

[0054] As Figures 1 - 3 shown, a plurality of long grooves 7 arranged in a circular array around the axis of the cylindrical rotating shaft 6 are provided on the outer side of the cylindrical rotating shaft 6, and a number of groove partition plates 8 are slidably connected inside the long grooves 7.

[0055] A magnet body 9 is fixedly connected to the outer side of the groove partition plate 8. The magnet bodies 9 on two adjacent groove partition plates 8 in the same long groove 7 are magnetically repellent. Two cylinders 5 are fixedly connected to both the left and right sides of the granulator housing 1. The end of the cylindrical rotating shaft 6 is rotatably connected inside the cylinder 5. The area of the long groove 7 located inside the granulator housing 1 is the shaping area, and the area of the long groove 7 located inside the cylinder 5 is the storage area. The groove partition plate 8 located inside the shaping area is an effective partition plate, and the groove partition plate 8 located inside the storage area is an ineffective partition plate. By moving the groove partition plate 8, the number of effective partition plates and ineffective partition plates can be adjusted. The shaping groove is the space between two adjacent effective partition plates in the long groove 7. By moving the effective partition plates, the length of the shaping groove can be adjusted, so as to adjust the length of the formed cylindrical feed pellets.

[0056] In order to move the groove partition plate 8, a driving group and a moving group are installed on the cylindrical rotating shaft 6. The moving group is in transmission connection with a plurality of groove partition plates 8 to drive the groove partition plates 8 to move inside the long groove 7. The driving group is in transmission connection with the moving group to input kinetic energy to the moving group.

[0057] As Figures 3 - 5 and Figure 7As shown, the movable group includes a plurality of rotating rods 17 rotatably connected inside the cylindrical rotating shaft 6, and the plurality of rotating rods 17 are arranged in a circular array with the axis of the cylindrical rotating shaft 6 as the center of the circle. The groove partition plate 8 inside the same long groove 7 is slidably connected to the same rotating rod 17, and two threaded wires 18 are fixedly connected to the outside of the rotating rod 17. The thread directions of the two threaded wires 18 are opposite. The groove partition plate 8 can be threadedly connected to the threaded wire 18, and the threaded wire 18 is located between the shaping area and the storage area. At this time, the threaded wire 18 can be used to limit the groove partition plate 8 inside the shaping area and the storage area, and under the action of magnetic force, the groove partition plate 8 closest to the threaded wire 18 and the threaded wire 18 are abutted against each other, and then the rotating rod 17 can be rotated to drive the groove partition plate 8 in contact with the two threaded wires 18 to move in the opposite direction, so that the groove partition plate 8 enters the shaping area or the storage area, and the number of effective partitions is adjusted.

[0058] The driving group includes a stepper motor, a gear ring 14, a second gear 15 and a plurality of first gears 13 that are rotatably connected to the stepper motor. The plurality of first gears 13 are respectively fixedly connected to the ends of a plurality of rotating rods 17. The gear ring 14 and the second gear 15 are both rotatably connected to the cylindrical rotating shaft 6. The second gear 15 and the plurality of first gears 13 are both meshedly connected to the gear ring 14. The stepper motor and the second gear 15 are transmission-connected. When adjusting the size of the groove, the stepper motor is started to drive the second gear 15 to rotate, and all the rotating rods 17 are driven to rotate synchronously through the gear ring 14. The threaded wire 18 pushes the groove partition plate 8 to move toward the shaping area or the storage area.

[0059] like Figures 3 - 7 As shown, a first through groove 19 connected to the long groove 7 can be opened inside the cylindrical rotating shaft 6 and located on the inner side of the long groove 7. The outer side of the groove dividing plate 8 is fixedly connected with a connecting block 16 which is slidably connected to the inside of the first through groove 19. A threaded hole is opened inside the connecting block 16. The inner diameter of the threaded hole is larger than the outer diameter of the rotating rod 17. The rotating rod 17 is inserted into the inside of the threaded hole, so that the groove dividing plate 8 is slidably connected to the outside of the rotating rod 17 through the threaded hole, and the groove dividing plate 8 is threadedly connected through the threaded hole and the threaded wire 18.

[0060] A guide groove 21 located on one side of the first through groove 19 is provided inside the cylindrical rotating shaft 6. The guide groove 21 is connected to the first through groove 19. A plurality of baffles 20 are slidably connected inside the guide groove 21. The baffles 20 and the connecting block 16 have the same width. After the groove partition plate 8 is moved, the baffle 20 opposite to the connecting block 16 is opened, and the remaining baffles 20 are closed. This can seal the opening connecting the first through groove 19 and the long groove 7, thereby reducing the phenomenon of raw materials entering the first through groove 19, thereby reducing the structural complexity of the area inside the long groove 7 that can contact the raw materials, reducing the resistance in this area, and reducing the phenomenon of raw materials being left inside the long groove 7 due to the complex structure.

[0061] An electromagnet 22 is fixedly connected inside the guiding groove 21. A magnetic stone 23 is fixedly connected to the baffle 20. A return spring 24 is fixedly connected between the electromagnet 22 and the magnetic stone 23. The magnetic stone 23 can be pushed by the return spring 24, so that the baffle 20 is initially located inside the first through groove 19. The electromagnet 22 can be powered by a conductive slip ring, and when the electromagnet 22 is energized, it magnetically attracts the magnetic stone 23. When moving the groove partition plate 8, by starting the electromagnet 22 to apply a pulling force to the magnetic stone 23, the baffle 20 is driven to move and open, opening the passage. After the groove partition plate 8 finishes moving, the electromagnet 22 is powered off, and the baffle 20 not opposite to the connecting block 16 can be moved into the first through groove 19 to complete the power-off closing.

[0062] As Figure 8 shown, a positioning groove 25 is opened at a position on the inner wall of the first through groove 19 close to the long groove 7. The baffle 20 can be clamped inside the positioning groove 25, so as to reduce the phenomenon that the baffle 20 is tilted due to the extrusion of raw materials.

[0063] As Figure 4 and Figure 7 shown, a plate body activity groove 26 communicating with the first through groove 19 is opened inside the cylindrical rotating shaft 6 and at a position inside the first through groove 19. A fixed pressing plate 27 that can abut against the connecting block 16 is slidably connected inside the plate body activity groove 26 of the cylindrical rotating shaft 6 for squeezing and positioning the connecting block 16. A second motor 32 is fixedly connected inside the cylindrical rotating shaft 6. The output end of the second motor 32 is fixedly connected with a central support 30. A plurality of extrusion bumps 31 are fixedly connected to the periphery of the central support 30. When the extrusion bumps 31 rotate to abut against the fixed pressing plate 27, the fixed pressing plate 27 can be pressurized, so that the fixed pressing plate 27 abuts against the connecting block 16 to squeeze and position the connecting block 16.

[0064] A plurality of card slots 28 are opened on one side of the fixed pressing plate 27 close to the connecting block 16. When the connecting block 16 abuts against the side wall of the card slot 28, the connecting block 16 can be positioned, improving the positioning stability of the connecting block 16. A tension spring 29 is also fixedly connected inside the plate body activity groove 26. One end of the tension spring 29 is fixedly connected to the fixed pressing plate 27 for pulling the fixed pressing plate 27 and the connecting block 16 to separate.

[0065] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special description and limitation.
