Description

Technical Field

[0001] The invention relates to the technical field of feed processing, and in particular to a chicken feed comprehensive processing system. Background Art

[0002] Laying hens are generally fed with artificial chicken feed. The production process of existing artificial chicken feed generally includes crushing grain raw materials into powder, screening, maturation, conditioning, drying and granulation, etc. Some also include puffing process. After the feed raw materials are puffed, the fragrance is increased, the palatability is improved, it can stimulate the appetite of animals, and it is also easier to digest.

[0003] The puffing process is a process after conditioning, where the feed is heated and pressurized, and then squeezed out of the die hole or suddenly ejected from the pressure vessel, the pressure drops rapidly and the volume suddenly expands. The puffing power is mainly caused by the energy release of the water inside the material. Theoretically, the greater the water content, the greater the amount of steam that can be generated, and the stronger the puffing power. However, when there is excess water, it will also have an adverse effect on expansion. Excess water is generally located on the surface of the powder of the material, which cannot become the puffing power. When the excess water is supplied with energy externally, it will first vaporize and occupy effective energy, affecting the puffing effect. Moreover, even if the material containing excess water undergoes the puffing process, its product will become soft due to the high water content of the finished product, and lose the unique flavor of the puffed product. Summary of the invention

[0004] The chicken feed comprehensive processing system proposed by the present invention can crush, screen and condition the feed raw materials, and can also perform puffing after conditioning. The material is dried twice before extrusion and puffing to reduce the external water of the material, improve the puffing quality, and reduce the adverse effects of excessive water content in the prior art granular chicken feed during puffing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The chicken feed comprehensive processing system includes a crushing drum, a screening box and a conditioning drum which are connected in sequence. A feed bin is arranged at one end of the crushing drum, and the other end of the crushing drum is connected to the feed section of the screening box. A feeding screw rod is arranged inside the crushing drum, and the feeding screw rod rotates to feed the feed raw materials. A crushing knife is arranged on the feeding screw rod, and the crushing knife can crush the feed raw materials during the feeding process to obtain feed powder. The screening box screens the feed powder, and the target feed powder can enter the conditioning drum.

[0007] Furthermore, a feeding dragon is arranged inside the conditioning cylinder, and a discharging sleeve and a puffing die are arranged at the tail of the conditioning cylinder. The feeding dragon delivers the feed powder to the discharging sleeve, and the feed powder is extruded and puffed in the puffing die to form puffed material.

[0008] Furthermore, the tempering cylinder is also provided with a plurality of steam pipes, which are respectively provided with steam inside the puffing cylinder at different positions of the tempering cylinder for tempering and pre-puffing treatment of the material inside the tempering cylinder.

[0009] Furthermore, the discharge sleeve is provided with a drying component for removing water from the outside of the material, and the drying component is located at the feeding end of the puffing mold. The drying component is used to remove excess water from the outside of the material, keep the material relatively dry before entering the puffing mold, and improve the puffing effect.

[0010] Preferably, the drying component includes a stirring sleeve and a drying core located inside the stirring sleeve.

[0011] Specifically, the stirring sleeve is fixedly connected to one end of the feeding dragon, and the stirring sleeve includes an outer supporting mesh sleeve coaxially arranged with the discharging sleeve, and a spiral stirring wire is arranged outside the outer supporting mesh sleeve. The material passes between the outer supporting mesh sleeve and the inner wall of the discharging sleeve, and the feeding dragon can drive the stirring sleeve to rotate, and the spiral stirring wire on the stirring sleeve can stir the material, so that the material is evenly contacted with the outer supporting mesh sleeve.

[0012] Furthermore, the drying core includes an inner supporting mesh sleeve coaxially arranged with the outer supporting mesh sleeve, and a flow gap for accommodating the passage of drying sheets is arranged between the outer wall of the inner supporting mesh sleeve and the inner wall of the outer supporting mesh sleeve. The drying sheets are water-absorbent materials. When the material in the discharge sleeve passes through the stirring sleeve, the material will contact the drying sheets through the outer supporting mesh sleeve, and the drying sheets can absorb external water contained in the material.

[0013] Preferably, the discharge sleeve is provided with an auxiliary sleeve on the outside of the outer support mesh sleeve, and the auxiliary sleeve is provided with an auxiliary gear ring and an auxiliary gear meshing with each other inside, and the auxiliary gear ring is coaxially arranged with the outer support mesh sleeve, and the axis of the auxiliary gear is perpendicular to the axis of the auxiliary gear ring. One end of the spiral stirring wire is rotationally connected to the outer support mesh sleeve, and the other end of the spiral stirring wire is fixedly connected to the auxiliary gear. When the outer support mesh sleeve rotates, the spiral stirring wire on the outer support mesh sleeve can drive the auxiliary gear to move relative to the auxiliary gear ring, so that the auxiliary gear rotates, thereby forming the self-rotation of the spiral stirring wire. The rotation of the spiral stirring wire can drive the material outside the outer support mesh sleeve to move perpendicular to the axis of the outer support mesh sleeve, prompting the material to have a tendency to move close to the outer support mesh sleeve, which is beneficial for the material to contact with the drying sheet and enhance the drying effect.

[0014] A rotating sealing sleeve is also provided on the inner wall of the auxiliary sleeve, which is rotatably connected to the auxiliary sleeve. A spiral stirring wire is connected to one end of the auxiliary gear and passes through the rotating sealing sleeve. The spiral stirring wire can drive the rotating sealing sleeve to rotate relative to the auxiliary sleeve. The rotating sealing sleeve is used to achieve sealing of the annular rolling path of the auxiliary gear.

[0015] Furthermore, two support rollers are arranged inside the inner support mesh sleeve, and the inner support mesh sleeve is provided with a notch for accommodating the drying sheet to enter and exit the flow gap. The drying sheet is tensioned and supported by the support rollers and the inner support mesh sleeve, and the drying sheet enters the flow gap from the notch of the inner support mesh sleeve, bypasses the inner support mesh sleeve for one circle, and then comes out from the notch of the inner support mesh sleeve, and finally passes through the support roller.

[0016] Furthermore, a sheet air drying pipe is also arranged inside the inner support mesh sleeve, and the sheet air drying pipe is located between the two support rollers. The sheet air drying pipe includes a hot air inlet pipe and a hot air outlet pipe, and the outlet of the hot air inlet pipe is opposite to the inlet of the hot air outlet pipe, and the drying sheet passes between the hot air inlet pipe and the hot air outlet pipe. The hot air inlet pipe is connected to the hot air pipe, and the hot air inlet pipe can perform hot blowing drying on the drying sheet and take out the moisture on the drying sheet, and the hot air outlet pipe takes away the moisture to achieve drying of the drying sheet.

[0017] Furthermore, the distance between the hot air inlet pipe outlet and the hot air outlet pipe inlet corresponds to the thickness of the drying sheet.

[0018] A drying motor for driving the support roller to rotate is arranged at one end of one of the support rollers. During the drying process of the drying sheet, the support roller can convey the drying sheet and keep the drying sheet flowing on the inner support mesh sleeve. The sheet air drying pipe can keep the drying sheet having a continuous and effective water absorption effect.

[0019] Since the hot air in the hot air outlet pipe contains water vapor, preferably, the hot air outlet pipe is connected to the steam pipe of the quenching and tempering cylinder, and the hot air can be passed into the steam pipe of the quenching and tempering cylinder for recycling.

[0020] A re-dehydration component is arranged inside the puffing mold. Preferably, the re-dehydration component includes a conveying wheel, a drying belt and a drying sleeve, the drying belt is supported by the conveying wheel, the conveying surface of the drying belt includes a recessed portion and a fitting portion, the recessed portion is located between the fitting portions, the recessed portion is a rough surface, the fitting portions of the conveying surfaces of the two drying belts are attached to each other, the conveying surface recessed portions of the two drying belts are combined to form a discharge die hole, the material in the discharge sleeve is squeezed out of the discharge die hole, the drying belt is a water-absorbent material, and can take out the moisture outside the strip material in the discharge die hole.

[0021] Furthermore, the drying sleeve is sleeved on the outside of the conveying surface of the drying belt, and a drying chamber is formed between the drying sleeve and the discharge die hole of the drying belt. The inlet of the drying chamber is connected to the hot air inlet pipe, and the outlet of the drying chamber is connected to the hot air outlet pipe. The hot air inlet pipe can perform hot-blow drying on the recessed part of the drying belt and bring out the moisture on the drying belt. The hot air outlet pipe takes away the moisture to achieve drying of the hole wall of the discharge die hole.

[0022] In the present invention, the extruded material can push the drying belt to move, and the direction of movement of the drying belt is the same as the direction in which the material is extruded, thereby reducing the extrusion pressure of the material and the probability of the discharge die hole being blocked.

[0023] Furthermore, a cutting knife is arranged outside the puffing die, and the cutting knife is rotatably connected to the puffing die through a rotating frame. The driving member drives the rotating frame to rotate, so that the cutting knife can cut the material coming out of the puffing die hole of the puffing die to obtain puffed particles.

[0024] Furthermore, the conditioning cylinder is provided with a detachable support seat at one end of the discharging sleeve, and the support seat is located inside the annular puffing mold. The support seat is fixedly connected to the inner support mesh sleeve, the support roller is rotatably connected to the support seat, and the drying motor is fixedly arranged on the support seat.

Figure 4 The spiral stirring wire 52 is a spiral sheet, and the axis of the spiral stirring wire 52 is perpendicular to the axis of the outer support mesh sleeve 51. The material passes between the outer support mesh sleeve 51 and the inner wall of the discharge sleeve 33, and the feeding dragon 3 drives the stirring sleeve 5 to rotate. The spiral stirring wire 52 on the stirring sleeve 5 can stir the material, so that the material contacts the outer support mesh sleeve 51 more evenly.

[0044] Furthermore, the drying core 4 includes an inner support mesh sleeve 41 coaxially arranged with the outer support mesh sleeve 51, and a flow gap for accommodating the passage of a drying sheet 9 is arranged between the outer wall of the inner support mesh sleeve 41 and the inner wall of the outer support mesh sleeve 51, and the drying sheet 9 is a water-absorbent material.

[0046] Furthermore, a sheet air-drying pipe is also provided inside the inner support mesh sleeve 41, and the sheet air-drying pipe is located between two support rollers 43, and the support rollers 43 are used to support the drying sheet 9, and to keep the drying sheet 9 flowing straight. The sheet air-drying pipe includes a hot air inlet pipe 43 and a hot air outlet pipe 44, and the outlet of the hot air inlet pipe 43 is opposite to the inlet of the hot air outlet pipe 44, and the drying sheet 9 passes between the hot air inlet pipe 43 and the hot air outlet pipe 44. The hot air inlet pipe 43 is connected to the hot air pipe, and the hot air inlet pipe 43 can perform hot blowing drying on the drying sheet 9 and take out the moisture on the drying sheet 9, and the hot air outlet pipe 44 takes away the moisture, so as to achieve drying of the drying sheet 9.

[0047] Furthermore, the distance between the outlet of the hot air inlet pipe 43 and the inlet of the hot air outlet pipe 44 corresponds to the thickness of the drying sheet 9. The outlet of the hot air inlet pipe 43 is in contact with one side of the drying sheet 9, and the inlet of the hot air outlet pipe 44 is in contact with the other side of the drying sheet 9, thereby reducing heat overflow and allowing the hot air from the hot air inlet pipe 43 to directly enter the hot air outlet pipe 44 after passing through the drying sheet 9, thereby enhancing the ability to take away moisture from the drying sheet 9.

During the drying process of the drying sheet, the support roller 43 can convey the drying sheet 9 and keep the drying sheet 9 flowing on the inner support mesh sleeve 41. The sheet air drying pipe can keep the drying sheet 9 having a continuous and effective water absorption effect.

[0049] Since the hot air in the hot air outlet pipe 44 contains water vapor, in this embodiment, the hot air outlet pipe 44 is connected to the steam pipe 32 of the quenching and tempering cylinder 3, and the hot air can be passed into the steam pipe 32 of the quenching and tempering cylinder 3 for recycling.

[0050] Furthermore, a cutting knife is provided outside the puffing die 6, and the cutting knife is rotatably connected to the puffing die 6 through a rotating frame.

[0051] Furthermore, one end of the discharging sleeve 33 of the puffing cylinder 1 is provided with a detachable support seat 8, see Figure 5 The support seat 8 is located inside the annular puffing die hole 6. The support seat 8 is fixedly connected to the inner support mesh sleeve 41, the support roller 43 is rotatably connected to the support seat 8, and the drying motor is fixedly arranged on the support seat 8. The support seat 8 is detachable, which is convenient for the overall replacement of the drying sheet 9.

[0052] The working process of the chicken feed comprehensive processing system in this embodiment includes the following steps:

[0053] Step A1: the material in the feed bin 10 enters the crushing cylinder 1, the feeding screw rod 101 rotates to feed the feed raw materials, and the crushing knife 102 crushes the feed raw materials during the feeding process to obtain feed powder;

[0054] Step A2: the feed powder enters the screening box 2, the screening box 2 screens the feed powder, and the target feed powder can enter the conditioning cylinder 3;

[0056] Step A4: the material enters the discharge sleeve 33 and passes through the stirring sleeve 5. The material passes between the outer support mesh sleeve 51 and the inner wall of the discharge sleeve 33. The spiral stirring wire 52 on the stirring sleeve 5 can stir the material so that the material is more evenly contacted with the drying sheet 9 inside the outer support mesh sleeve 51. The drying sheet 9 absorbs the external water contained in the material.

The hot air inlet pipe 43 of the sheet air drying pipe performs hot blowing drying on the drying sheet 9 and takes out the moisture on the drying sheet 9. The hot air outlet pipe 44 takes away the moisture to achieve drying of the drying sheet 9.

[0058] Step A5: After drying, the material enters the puffing die 6, where it is extruded and puffed. At the same time, the cutting knife 7 can cut the material in the puffing die hole 6 to obtain puffed particles.

[0059] The support seat 8 is a replaceable component, which is used to replace the drying sheet 9.

[0060] Example 2

One end of the spiral stirring wire 52 is rotatably connected to the outer support mesh sleeve 51, and the other end of the spiral stirring wire 52 is fixedly connected to the auxiliary gear 332.

[0062] When the outer support mesh sleeve 51 rotates, the spiral stirring wire 52 on the outer support mesh sleeve 51 can drive the auxiliary gear 332 to move relative to the auxiliary gear ring 3311, so that the auxiliary gear 332 rotates, thereby forming the self-rotation of the spiral stirring wire 52. The rotation of the spiral stirring wire 52 can drive the material outside the outer support mesh sleeve 51 to move perpendicular to the axis of the outer support mesh sleeve 51, causing the material to have a tendency to move close to the outer support mesh sleeve 51, which is beneficial for the material to contact with the drying sheet 9 and enhance the drying effect.

[0063] In this embodiment, a rotating sealing sleeve 3312 is also provided on the inner wall of the auxiliary sleeve 331. The rotating sealing sleeve 3312 is rotatably connected to the auxiliary sleeve 331. The spiral stirring wire 52 is connected to one end of the auxiliary gear 332 and passes through the rotating sealing sleeve 3312. The spiral stirring wire 52 can drive the rotating sealing sleeve 3312 to rotate relative to the auxiliary sleeve 331. The rotating sealing sleeve 3312 is used to achieve the sealing of the annular rolling path of the auxiliary gear 332.

[0064] Example 3

The conveying surface of the drying belt 64 includes a recessed portion 641 and a fitting portion 642. The recessed portion 641 is located between the fitting portions 642. The recessed portion 641 is a rough surface. The conveying surface fitting portions 642 of the two drying belts 64 are attached to each other. The conveying surface recessed portions 641 of the two drying belts 64 are combined to form a discharge die hole 62. The material in the discharge sleeve 33 is squeezed out of the discharge die hole 62. The drying belt 64 is a water-absorbent material and can take away the moisture outside the strip material in the discharge die hole 62.

[0066] Furthermore, the drying sleeve 65 is sleeved on the outside of the conveying surface of the drying belt 64, and a drying chamber 66 is formed between the drying sleeve 65 and the discharge die hole 62 of the drying belt 64. The inlet of the drying chamber 66 is connected to the hot air inlet pipe 43, and the outlet of the drying chamber 66 is connected to the hot air outlet pipe 44. The hot air inlet pipe 43 can perform hot blowing drying on the recessed portion 641 of the drying belt 64 and take out the moisture on the drying belt 64. The hot air outlet pipe 44 takes away the moisture to achieve drying of the hole wall of the discharge die hole 62.

[0067] The working process of the chicken feed comprehensive processing system in this embodiment includes the following steps:

[0068] Step B1: the material in the feed bin 10 enters the crushing drum 1, the feeding screw 101 rotates to feed the feed raw materials, and the crushing blade 102 crushes the feed raw materials during the feeding process to obtain feed powder;

[0069] Step B2: the feed powder enters the screening box 2, the screening box 2 screens the feed powder, and the target feed powder can enter the conditioning cylinder 3;

[0070] Step B3: the feeding dragon 31 and the stirring sleeve 5 rotate, the feeding dragon 3 conveys and extrude the material, and the steam pipe 32 performs conditioning and pre-expansion treatment on the material;

[0071] Step B4: the material enters the discharge sleeve 33 and passes through the stirring sleeve 5. The material passes between the outer support mesh sleeve 51 and the inner wall of the discharge sleeve 33. The spiral stirring wire 52 on the outer support mesh sleeve 51 can drive the auxiliary gear 332 to move relative to the auxiliary gear ring 3311, so that the auxiliary gear 32 rotates, thereby forming the self-rotation of the spiral stirring wire 52, which prompts the material to have a movement trend close to the outer support mesh sleeve 51, so that the material is more evenly in contact with the drying sheet 9 inside the outer support mesh sleeve 51, and the drying sheet 9 absorbs the external water contained in the material;

[0072] During the drying process of the drying sheet 9, the support roller 43 can convey the drying sheet 9 and keep the drying sheet 9 flowing on the inner support mesh sleeve 41. The hot air inlet pipe 43 of the sheet air drying pipe performs hot blowing drying on the drying sheet 9 and takes out the moisture on the drying sheet 9. The hot air outlet pipe 44 takes away the moisture to achieve drying of the drying sheet 9.

[0073] Step B5: After drying, the material enters the puffing die 6, and is squeezed into the discharge die hole 62 to form a strip material. The drying belt 64 can remove the moisture outside the strip material in the discharge die hole 62, and the dehydrated strip material comes out of the discharge die hole 62;

[0074] The drying chamber 66 outside the drying belt 64 can take away the moisture in the drying belt 64 through the hot air outlet pipe 44, so as to dry the hole wall of the discharge die hole 62;

[0075] Step B6: The cutting blade 7 can cut the material coming out of the puffing die 6 to obtain puffed particles.

[0076] In this embodiment, the extruded material can push the drying belt 64 to move. The direction of movement of the drying belt 64 is the same as the direction in which the material is extruded, thereby reducing the extrusion pressure of the material and the probability of the discharge die hole 62 being blocked.
