Description

Technical Field

[0001] The present invention relates to the field of feed processing, and more particularly to a feed and a processing method thereof. Background Art

[0002] There are many different ways to process feed, which mainly depends on the ingredients of the feed, the type of animal and the breeding environment. Compared with traditional feed, hollow feed is easier to chew, has a larger contact area with gastric juice during digestion, and is easier to absorb. At the same time, the feed is made hollow to make it easier to float, and it is also easier to observe its feeding situation when feeding aquatic animals. However, the existing processing method first makes the feed into hollow strips, and then divides and kneads it into balls to make it lower in density and easier to float. However, the wall thickness of the feed processed by this processing method is uneven, which is easy to break and affects its effect. Summary of the invention

[0003] The invention provides a feed and a processing method thereof, aiming to process hollow feed with uniform wall thickness.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A feed processing method comprises the following steps:

[0006] S1: First, ground fish meal, ground corn meal, fish oil, vitamins and lysine are stirred and mixed to form a raw material;

[0007] S2: The raw materials are then put into a processing device and extruded into strip feed;

[0008] S3: forming the extruded feed into a ball shape;

[0009] S4: Finally, the spherical feed is dried and packaged.

[0010] The processing equipment includes a bracket, on which two molding shells are arranged, a plurality of outer cylinders are arranged between the two molding shells, two inner cylinders are slidably connected between every two adjacent outer cylinders, a rubber cylinder is fixed between two adjacent inner cylinders, and the rubber cylinder is filled with inert gas.

[0011] The feed processed by the feed processing method comprises 40-50% of fish meal, 15-25% of fish oil, 10-20% of corn meal, 0.5-2% of vitamins and minerals, and 1-5% of lysine. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like Figure 1 , a feed processing method, comprising the following steps;

[0031] S1: Mix fish meal, corn meal, fish oil, vitamins and lysine to form raw materials, add appropriate amount of water and heat them during mixing to make them fully mixed for easy extrusion and shaping;

[0032] S2: putting the raw materials into the processing equipment for extrusion, and extruding the mixed raw materials into long strips with irregular hollow centers;

[0033] S3: forming the extruded feed into a spherical shape, so that the feed forms a spherical shape with uniform wall thickness;

[0034] S4: Dry the surface of the spherical feed to avoid dust and other impurities from sticking to it and to facilitate storage and transportation, and then pack it.

[0035] like Figures 2 to 4 , in order to solve the problem of uniform wall thickness of hollow feed.

[0036] A plurality of outer cylinders 101 are arranged at the center of the molded shell 11, two inner cylinders 102 are slidably connected between two adjacent outer cylinders 101, and a rubber cylinder 103 is arranged between two adjacent inner cylinders 102 to seal the space between the two inner cylinders 102, and the sealed space is filled with inert gas.

[0037] When the device is working, firstly, every two adjacent inner cylinders 102 are driven to move relative to each other, thereby squeezing the inert gas inside, so that the rubber cylinder 103 is squeezed to expand to the surroundings into a circle, and then the mixed raw materials are squeezed into the molding shell 11 from one side. When the molding shell 11 is filled with feed raw materials, the inner outer cylinder 101 and the rubber cylinder 103 support the center of the feed raw materials, so that a cylindrical and circular space is formed inside. After squeezing the feed into the molding shell 11, the inner cylinder 102 is driven to move in the opposite direction, so that the diameter of the rubber cylinder 103 is the same as that of the outer cylinder 101, and then the long feed is mixed with the whole The feed is separated into two parts, and then the long feed is made into a sphere. Since the internal gap is an alternating shape of a column and a sphere, the feed is divided from the columnar part when it is squeezed and kneaded into a sphere, and then it is kneaded into a sphere. The proportion of feed in the columnar part is greater than that in the spherical part. In the process of cutting and kneading, this part has better ductility, which avoids breakage and uneven wall thickness. As a result, the various parts of the feed are evenly stressed during transportation and are not easily damaged. At the same time, it can lock in internal moisture for animals to obtain from the inside. When making hollow fish feed, it can also make it float in water and not easily dissolve, reducing water pollution.

[0038] like Figures 3 to 5, in order to solve the problem that the inner cylinder 102 moves away from the center of the long feed.

[0039] Two slide rails 105 are welded inside the multiple outer cylinders 101. One end of the two outer cylinders 101 on both sides is closed. The inner cylinder 102 is slidably connected to the slide rails 105. The threaded rod 104 is rotatably connected between the two slide rails 105. The threaded rod 104 and the inner cylinder 102 are threadedly driven.

[0040] When the inner cylinder 102 needs to be moved, the threaded rod 104 is driven to rotate, and the threaded connection directions between the two adjacent inner cylinders 102 and the threaded rod 104 are opposite, so that the two adjacent inner cylinders 102 can be synchronously moved toward and away from the center by the rotation of the threaded rod 104. The multiple outer cylinders 101 are all fixed on the slide rail 105, and then after the feed raw materials are squeezed into the molding shell 11, they are moved from one side as a whole to be extracted from the center of the feed, and then the two molding shells 11 are separated to allow the strip feed to fall for subsequent processing.

[0041] like Figure 4 and Figure 5 , in order to solve the problem that the rubber tube 103 has insufficient support force on the inside of the feed when the extrusion pressure is too large.

[0042] Each arc plate 107 is rotatably connected to two cross-arranged first connecting rods 106, and the other end of the first connecting rod 106 is rotatably connected to the corresponding inner cylinder 102. Each first connecting rod 106 is provided with a slide groove 108, and two corresponding slide grooves 108 are slidably connected to support rods 109, and the other end of the support rod 109 is fixed to the slide rail 105.

[0043] When the two corresponding inner cylinders 102 move, they simultaneously push one ends of the two first connecting rods 106 closer together, thereby causing the other ends to extend outward, thereby driving the arc plate 107 to support the rubber cylinder 103 in all directions, thereby preventing the rubber cylinder 103 from deforming when the squeezing pressure on the feed is too large, resulting in uneven hollow parts of the strip feed. At the same time, when the two first connecting rods 106 move, the slide grooves 108 thereon are always slidably connected to the support rods 109, thereby preventing the support from being unstable due to shaking.

[0044] like Figure 6 and Figure 7 , in order to solve the problem of squeezing the feed raw materials into the forming shell 11.

[0045] The extrusion tube 12 is welded on the bracket 14, the hopper 201 is welded above the extrusion tube 12, the interior of the hopper 201 is connected to the interior of the extrusion tube 12, the sleeve 202 is rotatably connected to the center of the extrusion tube 12, the outside of the sleeve 202 is welded with a spiral blade 203, the pulley 204 is key-connected to the sleeve 202, the motor 401 is fixed to the bracket 14 with bolts, and the output shaft of the motor is driven by the first pulley 204.

[0046] The feed material is put into the hopper 201, and then the motor 401 is driven to work, and then the first pulley 204 is driven to rotate through the belt, and then the sleeve 202 is driven to rotate, and then the spiral blade 203 is driven to rotate, and then the feed material in the hopper 201 is transported forward from the extrusion tube 12, and then it is squeezed into the forming shell 11 for shaping. The inner wall diameter of the sleeve 202 is larger than the diameter of the outer cylinder 101, and then after the extrusion is completed, it is convenient to move the slide rail 105 outward from one side to drive multiple outer cylinders 101 and inner cylinders 102 to take them out as a whole.

[0047] like Figure 8 and Fig. 9 , in order to solve the problem of processing strip feed into spherical shape.

[0048] The two forming rollers 13 are located below the forming shell 11 . One end of each second connecting rod 301 is rotatably connected to one end of the forming roller 13 . The other ends of the two second connecting rods 301 on the same side are rotatably connected to the bracket 14 .

[0049] After the two forming shells 11 are separated, the strip feed falls from above between the two forming rollers 13. At this time, the two forming rollers 13 are driven to rotate and the two forming rollers 13 are brought close to each other. The forming rollers 13 are provided with arc-shaped depressions and narrower protrusions. The narrower protrusions are located at the position where the interior of the strip feed is cylindrical and hollow, so that the strip feed can be cut during rotation. Afterwards, as the forming rollers 13 rotate, the depressions on the forming rollers 13 can knead the cut feed to make it spherical.

[0050] like Figure 8 and Fig. 9 , in order to solve the problem of the rotation of the forming roller 13.

[0051] The output shaft of the motor 401 is connected to the second pulley 304 via a belt. The second pulley 304 rotates coaxially with the second gear 303. The rotation center of the third gear 303 is the same as the rotation center of the two second connecting rods 301 on the same side. The second gear 303 is respectively meshed with the two first gears 302, and the first gears 302 are respectively key-connected to the corresponding forming rollers 13.

[0052] When the motor 401 is working, the output shaft of the motor 401 rotates and drives the second pulley 304 through the belt, thereby driving the second gear 303 to rotate, and then meshing and driving the first gear 302 to rotate, thereby driving the two forming rollers 13 to rotate, and kneading the feed into a ball shape. The two forming rollers 13 approach each other when rotating, and the first gear 302 and the second gear 303 are respectively located at the two ends of the second connecting rod 301, thereby ensuring that the first gear 302 can always be driven to rotate by the second gear 303 when the two forming rollers 13 approach each other.

[0053] like Fig.10 , in order to solve the problem of movement of the molded shell 11.

[0054] The two fixing rods 15 are welded to the two molded shells 11 respectively. Each fixing rod 15 is slidably connected to the bracket 14. The first screw rod 501 is rotatably connected to the bracket 14. The first screw rod 501 and the two fixing rods 15 are threadedly connected.

[0055] After the feed is squeezed into the molding shell 11, the inner slide rail 105 is partially pulled out, and then the first screw rod 501 is driven to rotate. The first screw rod 501 is provided with threads with opposite rotation directions at both ends, and then the two fixing rods 15 are driven by the screw to move in opposite directions, thereby driving the two molding shells 11 to move synchronously to both sides, so that the strip feed falls from between the two molding shells 11 to between the two molding rollers 13, so as to be made into a ball.

[0056] like Fig. 9 , in order to solve the problem of the two forming rollers 13 being relatively close to or far away from each other.

[0057] The bracket 14 is rotatably connected with a second screw rod 502 , which is threadedly connected to two sliders 306 . Each slider 306 is slidably connected in a corresponding track block 305 , and each track block 305 is rotatably connected to a corresponding forming roller 13 .

[0058] The second screw rod 502 is driven to rotate. The second screw rod 502 is provided with two sections of threads with opposite rotation directions, thereby driving the two sliders 306 to approach or move away synchronously, thereby driving the two track blocks 305 to approach or move away synchronously, thereby driving the two forming rollers 13 to approach or move away synchronously. Since the forming roller 13 is connected to the bracket 14 through the second connecting rod 301, the forming roller 13 will also be displaced in the up and down directions during the process of moving left and right, thereby driving the track block 305 to move outside the slider 306 to avoid jamming.

[0059] A feed processed by a feed processing method comprises 40-50% of fish meal, 15-25% of fish oil, 10-20% of corn meal, 0.5-2% of vitamins and minerals, and 1-5% of lysine.
