Description

Technical Field

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

[0002] For pelletized puffed chicken feed, it needs to be processed by puffing process after preparation. Puffing process refers to the process of heating and pressurizing the feed, and squeezing it out of the die hole or suddenly spraying it out of the pressure container, and the pressure drops rapidly and the volume suddenly expands.

[0003] The expansion 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 expansion 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 material and cannot become the expansion power. When the excess water is supplied with energy externally, it will first vaporize and occupy effective energy, affecting the expansion effect. Moreover, even if the material containing excess water undergoes the expansion process, its product will become soft due to the high water content of the finished product, and lose the unique flavor of the expanded product. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of the adverse effect of excessive moisture in the puffing of pellet chicken feed in the prior art, and to propose a pellet chicken feed puffing processing equipment, which performs a micro-drying treatment on the material before extrusion and puffing to reduce the external water of the material and improve the puffing quality.

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

[0006] The pellet chicken feed puffing processing equipment comprises a puffing cylinder, a feed bin is arranged at one end of the puffing cylinder, a puffing die hole is arranged at the other end of the puffing cylinder, and a feeding dragon is arranged inside the puffing cylinder. The material enters the puffing cylinder from the feed bin, and the feeding dragon delivers the material to the puffing die hole, where the material is squeezed out of the puffing die hole for puffing to form puffed material. A steam pipe is arranged on the side of the puffing cylinder, and the steam pipe comprises at least a first steam pipe and a second steam pipe, and the first steam pipe and the second steam pipe respectively provide steam inside the puffing cylinder at different positions of the puffing cylinder, which is used for tempering and pre-puffing treatment of the material inside the puffing cylinder.

[0007] Furthermore, a drying component is arranged at one end of the puffing cylinder close to the puffing die hole, and the drying component is located at the feeding end of the puffing die hole. The drying component is used to remove excess moisture outside the material, keep the material relatively dry before entering the puffing die hole, and improve the puffing effect.

[0008] Preferably, the drying component includes a stirring sleeve and a drying core located inside the stirring sleeve.

[0009] 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 expanding cylinder, 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 expanding cylinder, 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.

[0010] 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 puffing cylinder 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.

[0011] Preferably, the puffing cylinder 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, 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 rotatably 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.

[0012] 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.

[0013] Furthermore, a feeding roller and a receiving roller are arranged inside the inner support mesh sleeve, and the feeding roller and the receiving roller rotate synchronously. 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 comes out of the feeding roller, passes through the notch of the inner support mesh sleeve, enters the flow gap, bypasses the inner support mesh sleeve for one circle, and comes out of the notch of the inner support mesh sleeve to be wound up by the receiving roller. During the drying process of the drying sheet, the feeding roller feeds the material and the receiving roller collects the material, which can keep the flow of the drying sheet on the inner support mesh sleeve and maintain a continuous and effective water absorption effect.

[0014] Preferably, a sheet air drying pipe is further arranged inside the inner support mesh sleeve, and the sheet air drying pipe comprises a hot air inlet pipe and a hot air outlet pipe, 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, thereby realizing the drying and rolling of the drying sheet.

[0015] 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.

[0016] Preferably, the unloading roller and the receiving roller are both provided with corresponding sheet air drying pipes. When the unloading roller and the receiving roller are both reversed, the dried sheet can be reused.

[0017] 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 expansion cylinder, and the hot air can be passed into the steam pipe of the expansion cylinder for recycling.

[0018] Furthermore, a cutting knife is arranged outside the puffing die hole, and the cutting knife is rotatably connected to the puffing cylinder through a rotating frame. The driving member drives the rotating frame to rotate, so that the cutting knife can cut the material in the puffing die hole to obtain puffed particles.

[0019] Furthermore, a detachable support seat is provided at one end of the puffing cylinder where the puffing die hole is provided, and the support seat is located inside the annular puffing die hole. The support seat is fixedly connected to the inner support mesh sleeve, and the discharge roller and the receiving roller are respectively rotatably connected to the support seat, and the support seat is also provided with a driving member for driving the discharge roller and the receiving roller to rotate. The support seat is detachable, which is convenient for the overall replacement of the drying sheet.

The material enters the puffing cylinder 1 from the feed bin 2, and the feeding dragon 3 delivers the material to the puffing die hole 6, and the material is squeezed out of the puffing die hole 6 and puffed to form puffed material. Furthermore, a cutting knife 7 is arranged outside the puffing die hole 6, and the cutting knife 7 is rotatably connected to the puffing cylinder 1 through a rotating frame 61. The driving member drives the rotating frame 61 to rotate, so that the cutting knife 7 can cut the material in the puffing die hole 6 to obtain puffed pellets.

[0032] Steam pipes are arranged on the side of the puffing cylinder 1, and the steam pipes include at least a first steam pipe 101 and a second steam pipe 102. The first steam pipe 101 and the second steam pipe 102 respectively provide steam inside the puffing cylinder 1 at different positions of the puffing cylinder 1, so as to be used for tempering and pre-puffing treatment of the material inside the puffing cylinder 1.

[0033] Furthermore, a drying component is provided at one end of the puffing cylinder 1 close to the puffing die hole 6, and the drying component is located at the feeding end of the puffing die hole 6. The drying component is used to remove excess moisture from the outside of the material, keep the material relatively dry before entering the puffing die hole 6, and improve the puffing effect.

[0034] refer to Figure 2 The drying component includes a stirring sleeve 5 and a drying core 4 located inside the stirring sleeve 5 .

[0035] Specifically, the stirring sleeve 5 is fixedly connected to one end of the feeding dragon 3, and the stirring sleeve 5 includes an outer supporting mesh sleeve 51 coaxially arranged with the expanding cylinder 1, and a spiral stirring wire 52 is arranged outside the outer supporting mesh sleeve 51. 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 supporting mesh sleeve 51. The material passes between the outer supporting mesh sleeve 51 and the inner wall of the puffing cylinder 1, 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 supporting mesh sleeve 51 more evenly.

[0036] Furthermore, the drying core 4 includes an inner supporting mesh sleeve 41 coaxially arranged with the outer supporting 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 supporting mesh sleeve 41 and the inner wall of the outer supporting mesh sleeve 51. The drying sheet 9 is a water-absorbent material. When the material in the puffing cylinder 1 passes through the stirring sleeve 5, the material will contact the drying sheet 9 through the outer supporting mesh sleeve 51, and the drying sheet 9 can absorb the external water contained in the material.

[0037] refer to Figure 3 A feeding roller 42 and a receiving roller 43 are arranged inside the inner support mesh sleeve 41. The feeding roller 42 and the receiving roller 43 are connected by a synchronous belt 44, and the feeding roller 42 and the receiving roller 43 can rotate synchronously. The inner support mesh sleeve 41 is provided with a notch for accommodating the drying sheet 9 to enter and exit the flow gap. The drying sheet 9 comes out of the feeding roller 42, passes through the notch of the inner support mesh sleeve 41, enters the flow gap, bypasses the inner support mesh sleeve 41 for one circle, and comes out of the notch of the inner support mesh sleeve 41 to be wound up by the receiving roller 43. During the drying process of the drying sheet 9, the feeding roller 42 discharges the material, and the receiving roller 43 collects the material, which can keep the drying sheet 9 flowing on the inner support mesh sleeve 41 and maintain a continuous and effective water absorption effect.

[0038] Furthermore, one end of the puffing tube 1 where the puffing die hole 6 is provided is provided with a detachably connected support seat 8, Figure 5 The support seat 8 is located inside the annular expansion die hole 6. The support seat 8 is fixedly connected to the inner support mesh sleeve 41, and the discharge roller 42 and the receiving roller 43 are respectively rotatably connected to the support seat 8. The support seat 8 is also provided with a driving member for driving the discharge roller 42 and the receiving roller 43 to rotate. The support seat 8 is detachable, which is convenient for the overall replacement of the drying sheet 9.

[0039] The working process of the pellet chicken feed puffing processing equipment in this embodiment is as follows:

[0040] Preparation: Install the support seat 8 on the puffing cylinder 1, and keep the dry sheet 9 coming out from the discharge roller 42, passing through the gap of the inner support mesh sleeve 41 to enter the flow gap, bypass the inner support mesh sleeve 41 for one circle, and then come out from the gap of the inner support mesh sleeve 41 to be rolled up by the collection roller 43.

[0041] Step A1: the feeding dragon 3 and the stirring sleeve 5 rotate, the material enters the expanding cylinder 1 from the feeding bin 2, and the feeding dragon 3 conveys and extrude the material;

[0042] Step A2: the material passes through the first steam pipe 101, and the material is initially conditioned;

[0043] Step A3: the material passes through the second steam pipe 102, and the material is tempered and pre-expanded again;

[0044] Step A4: the material passes through the stirring sleeve 5, and the material passes between the outer supporting mesh sleeve 51 and the inner wall of the puffing cylinder 1. The spiral stirring wires 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 supporting mesh sleeve 51, and the drying sheet 9 absorbs the external water contained in the material;

[0045] During the drying process of the drying sheet 9, the feeding roller 42 feeds the material and the collecting roller 43 collects the material, so as to keep the drying sheet 9 flowing on the inner supporting mesh sleeve 41 and maintain a continuous and effective water absorption effect;

[0046] Step A5: After drying, the material enters the puffing die hole 6, where it is extruded and puffed. At the same time, the cutting blade 7 can cut the material in the puffing die hole 6 to obtain puffed particles.

[0047] The support seat 8 is a replaceable part, which is used to realize the replacement of the drying tablet 9. When the drying tablet 9 on the discharge roller 42 is used up, the support seat 8 needs to be removed, and another support seat 8 needs to be replaced for continued use.

[0048] Example 2

[0049] refer to Figure 6 and Figure 7, which is different from the embodiment 1, the expanding cylinder 1 in this embodiment is provided with an auxiliary sleeve 11 outside the outer supporting mesh sleeve 51, and the auxiliary sleeve 11 is provided with an auxiliary gear ring 111 and an auxiliary gear 12 meshing with each other inside, the auxiliary gear ring 111 is coaxially arranged with the outer supporting mesh sleeve 51, and the axis of the auxiliary gear 12 is perpendicular to the axis of the auxiliary gear ring 111. One end of the spiral stirring wire 52 is rotatably connected to the outer supporting mesh sleeve 51, and the other end of the spiral stirring wire 52 is fixedly connected to the auxiliary gear 12.

[0050] 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 12 to move relative to the auxiliary gear ring 111, so that the auxiliary gear 12 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.

[0051] In this embodiment, a rotating sealing sleeve 112 is also provided on the inner wall of the auxiliary sleeve 11. The rotating sealing sleeve 112 is rotatably connected to the auxiliary sleeve 11. The spiral stirring wire 52 is connected to one end of the auxiliary gear 12 and passes through the rotating sealing sleeve 112. The spiral stirring wire 52 can drive the rotating sealing sleeve 112 to rotate relative to the auxiliary sleeve 11. The rotating sealing sleeve 112 is used to achieve the sealing of the annular rolling path of the auxiliary gear 12.

[0052] Example 3

[0053] Different from the embodiment 2, the inner support mesh sleeve 41 in this embodiment is further provided with a sheet air drying pipe, which includes a hot air inlet pipe 45 and a hot air outlet pipe 46. The outlet of the hot air inlet pipe 45 is opposite to the inlet of the hot air outlet pipe 46, and the drying sheet 9 passes between the hot air inlet pipe 45 and the hot air outlet pipe 46. The hot air inlet pipe 45 is connected to the hot air pipe, and the hot air inlet pipe 45 can perform hot blowing drying on the drying sheet 9 and take out the moisture on the drying sheet 9. The hot air outlet pipe 46 takes away the moisture, so as to realize the drying and rolling of the drying sheet 9.

[0054] In this embodiment, a support roller 47 is further provided inside the inner support mesh sleeve 41. The support roller 47 is used to support the drying sheet 9. The support roller 47 is located on both sides of the hot air inlet pipe 45 and the hot air outlet pipe 46 to keep the drying sheet 9 flowing straight.

[0055] Furthermore, the distance between the outlet of the hot air inlet pipe 45 and the inlet of the hot air outlet pipe 46 corresponds to the thickness of the drying sheet 9. The outlet of the hot air inlet pipe 45 is in contact with one side of the drying sheet 9, and the inlet of the hot air outlet pipe 46 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 45 to directly enter the hot air outlet pipe 46 after passing through the drying sheet 9, thereby enhancing the ability to remove moisture from the drying sheet 9.

[0056] In this embodiment, the discharge roller 42 and the receiving roller 43 are both provided with corresponding sheet air drying pipes. When the discharge roller 42 and the receiving roller 43 are both reversed, the dried sheet 9 can be reused.

[0057] Since the hot air in the hot air outlet pipe 46 contains water vapor, in this embodiment, the hot air outlet pipe 46 is connected to the second steam pipe 102 of the expanding cylinder 1, and the hot air can be passed into the steam pipe of the expanding cylinder 1 for recycling.

[0058] The working process of the pellet chicken feed puffing processing equipment in this embodiment is as follows:

[0059] Preparation: Install the support seat 8 on the puffing cylinder 1, and keep the dry sheet 9 coming out from the discharge roller 42, passing through the gap of the inner support mesh sleeve 41 to enter the flow gap, bypass the inner support mesh sleeve 41 for one circle, and then come out from the gap of the inner support mesh sleeve 41 to be rolled up by the collection roller 43; at the same time, connect the hot air inlet pipe 45 and the hot air outlet pipe 46 to the equipment accordingly.

[0060] Step B1: the feeding dragon 3 and the stirring sleeve 5 rotate, the material enters the expanding cylinder 1 from the feeding bin 2, and the feeding dragon 3 conveys and extrude the material;

[0061] Step B2: the material passes through the first steam pipe 101, and the material is initially conditioned;

[0062] Step B3: the material passes through the second steam pipe 102, and the material is tempered and pre-expanded again;

[0063] Step B4: the material passes through the stirring sleeve 5, and the material passes between the outer supporting mesh sleeve 51 and the inner wall of the puffing cylinder 1. The spiral stirring wire 52 on the outer supporting mesh sleeve 51 can drive the auxiliary gear 12 to move relative to the auxiliary gear ring 111, so that the auxiliary gear 12 rotates, and then the spiral stirring wire 52 rotates, which makes the material move closer to the outer supporting mesh sleeve 51, so that the material contacts the drying sheet 9 inside the outer supporting mesh sleeve 51 more evenly, and the drying sheet 9 absorbs the external water contained in the material;

[0064] During the drying process of the drying sheet 9, the feeding roller 42 feeds the material, and the collecting roller 43 collects the material, so as to keep the drying sheet 9 flowing on the inner supporting mesh sleeve 41 and maintain a continuous and effective water absorption effect. Before the drying sheet 9 is rolled up, the drying sheet 9 passes between the hot air inlet pipe 45 and the hot air outlet pipe 46. The hot air inlet pipe 45 can perform hot blowing drying on the drying sheet 9 and take out the moisture on the drying sheet 9. The hot air outlet pipe 46 takes away the moisture, so as to realize the drying and rolling of the drying sheet 9.

[0065] The dry sheet 9 wound up by the receiving roller 43 can be released again by the reverse rotation of the unwinding roller 42 and the receiving roller 43, and wound up by the unwinding roller 42. At this time, the sheet air drying pipe of the unwinding roller 42 works, and the sheet air drying pipe of the receiving roller 43 does not work. In this way, the dry sheet 9 can be reused.

[0066] Step B5: After drying, the material enters the puffing die hole 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.

[0067] The support seat 8 is a replaceable component, which is used to replace the drying tablet 9. When the drying tablet 9 needs to be replaced, the support seat 8 can be removed and replaced with another support seat 8 for continued use.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
