Description

Technical Field

DETAILED DESCRIPTION

[0046] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0047] See also Figure 1and Figure 2 , is a feed preparation device containing natural plant additives for feed disclosed in the present application, mainly composed of a preparation table 11, an endless conveyor belt 12, a feeder 2, a screw extruder 3 and an electric extrusion roller 4, etc. The endless conveyor belt 12 is wound around the preparation table 11 and powered by the preparation table 11. A rotating roller and a driving motor are installed on the preparation table 11, and the driving motor is connected to one of the rotating rollers. When the rotating roller rotates, the endless conveyor belt 12 is driven to rotate on the preparation table 11 by friction.

[0048] A plurality of annular grooves 121 are arranged at intervals on the endless conveyor belt 12 . The annular grooves 121 are arranged in parallel on the endless conveyor belt 12 (adjacent annular grooves 121 are arranged in parallel). The length of the annular grooves 121 is equal to the length of the endless conveyor belt 12 .

[0049] The function of the annular groove 121 is to temporarily store the raw materials and drive the raw materials to pass through each processing step in sequence.

[0050] A plurality of feeders 2 are also provided on the preparation table 11 , each feeder 2 comprises a first spraying module 21 and a second spraying module 22 , the first spraying module 21 is used for spraying powder onto the endless conveyor belt 12 , and the second spraying module 22 is used for spraying adhesive onto the endless conveyor belt 12 .

[0051] Here, the explanation is combined with feed pellets. The production of feed pellets is to add water to a powder composed of multiple raw materials, stir it, shake it or extrude it into shape, and then dry it to fix it. In the present application, the first spraying module 21 first sprays a layer of powder on the annular groove 121, and the second spraying module 22 then sprays a layer of adhesive (water) on the powder. The powder and the adhesive are stacked in a stacked manner, so that the adhesive (water) can penetrate into the powder. In this way, in the subsequent extrusion process, multiple layers of powder can be bonded together because each layer of powder can be penetrated by the adhesive (water). Figure 3 shown.

[0052] The method of stacking multiple layers of powder can control the thickness of a single layer of powder within an appropriate range so that it can be quickly penetrated by the adhesive (water).

[0053] The screw extruder 3 is installed on the preparation table 11, and its function is to lay the wet material containing the edible natural plant additive into the annular groove 121. The wet material of the edible natural plant additive consists of the edible natural plant additive, auxiliary agent (starch, corn powder, soybean meal powder) and water, etc. The function of the auxiliary agent is to make the edible natural plant additive be evenly laid in the annular groove 121.

[0054] It should be understood that the amount of natural plant additives added is much smaller than the amount of powder. In order to evenly spread it on the powder, auxiliary agents (starch, corn flour, soybean meal powder) are needed to enable the natural plant additives to be evenly extruded from the screw extruder 3.

[0055] The electric squeezing roller 4 installed on the preparation table 11 is used to apply pressure to the semi-finished product in the annular groove 121 and cut it. The purpose of applying pressure is to shape the powder, adhesive (water) and wet material containing edible natural plant additives to obtain strip feed. The purpose of cutting is to cut the strip feed into feed particles.

[0056] Therefore, according to the above description, it can be obtained that in the working direction of the endless conveyor belt 12 , there are feeders 2 in front of and behind the screw extruder 3 , and the electric squeezing roller 4 is located behind the last group of feeders 2 .

[0057] See also Figure 1 The feeders 2 can also be considered as being divided into two groups. The two groups of feeders 2 are used to lay a material layer (composed of powder and adhesive) in the annular groove 121. The two material layers can wrap the wet material containing the feedable natural plant additive extruded by the screw extruder 3. In this way, the feed particles can be used to form a protective layer to reduce the contact of the feedable natural plant additive with oxygen and ultraviolet rays, thereby achieving the purpose of avoiding denaturation and failure. Figure 4 shown.

[0058] In the above process, the amount of binder (water) used is slightly more than that used in the granulation or post-extrusion molding process, in order to enable the multi-layer powder to be extruded and molded during the extrusion process of the electric extrusion roller 4.

[0059] After the extruded feed pellets fall from the endless conveyor belt 12, they are sent to the dryer for drying. It should be noted that the far infrared drying and low temperature drying methods are used as much as possible in the drying process. The far infrared drying method can increase the internal and external temperatures of the feed pellets synchronously, while the low temperature drying method can avoid the breakage of the feed pellets and the generation of excessive debris.

[0060] The feed particles can be dropped from the endless conveyor belt 12 by vibration, and a layer of a dropping agent (such as starch) can be sprayed on the endless conveyor belt 12 in advance. The dropping agent can remain dry during the entire production process, so that the feed particles can be easily dropped from the endless conveyor belt 12.

[0061] As a specific embodiment of the feed preparation equipment containing edible natural plant additives provided in the application, the shape of the annular groove 121 is adjusted, and the width of the annular groove 121 tends to decrease in the direction close to the bottom surface of the annular groove 121, so that during extrusion molding, the raw materials in the annular groove 121 can be accumulated together, which can increase the pressure during extrusion.

[0062] As a specific embodiment of the feed preparation equipment containing edible natural plant additives provided in the application, the edges of any two adjacent annular grooves 121 overlap, so that when laying powder into the annular grooves 121, the powder can fall into the annular grooves 121, which can effectively improve the utilization rate of the powder.

[0063] It should be understood that when there is a plane at the edge of two adjacent annular grooves 121, a portion of the powder will fall on this plane. This portion of the powder cannot participate in the production process of feed particles and needs to be screened out from the pellet feed and dried, crushed and regenerated before it can be reused.

[0064] When the edges of any two adjacent annular grooves 121 overlap, the powder can fall into the annular grooves 121, so that except for some powder at the edges on both sides of the annular conveyor belt 12, the powder at other positions can be made into feed particles.

[0065] See also Figure 2 and Figure 5 The first spraying module 21 is composed of a transverse conveying auger 211, a powder pipeline 212, a powder nozzle 213 and a compressed air source 214. The transverse conveying auger 211 is arranged on the preparation table 11, on which a plurality of powder pipelines 212 are installed, and the powder pipeline 212 is equipped with a powder nozzle 213.

[0066] The transverse conveying auger 211 conveys the powder to each powder pipeline 212 , and the powder spraying head 213 sprays the powder onto the endless conveyor belt 12 with the aid of compressed air.

[0067] The compressed air source 214 is connected to the powder spray nozzle 213 to input the compressed air into the powder spray nozzle 213 .

[0068] In some possible implementations, the compressed air source 214 is composed of an air tank, a compressor connected to the air tank, and an air line. The air line is connected to the air tank and the powder nozzle 213, and a valve is installed on it. When the valve is opened, the compressed air in the air tank flows into the powder nozzle 213 through the air line.

[0069] See also Figure 2 and Figure 6The second spraying module 22 is composed of a transverse pipe 221, a water distribution pipe 222, an atomizing nozzle 223 and a booster pump 224. The transverse pipe 221 is fixed on the preparation table 11, and multiple water distribution pipes 222 are installed on it. These water distribution pipes 222 are arranged at intervals on the transverse pipe 221, and each water distribution pipe 222 is equipped with an atomizing nozzle 223.

[0070] The transverse pipe 221 is connected to the booster pump 224. During the production process, the booster pump 224 pressurizes the adhesive (water) and injects it into the transverse pipe 221. The adhesive (water) in the transverse pipe 221 will flow into the water distribution pipe 222 and then be sprayed out from the atomizing nozzle 223.

[0071] See also Figure 7 The screw extruder 3 is composed of a feeding auger 31, an extrusion tube 32 and a nozzle 33. The feeding auger 31 is fixedly mounted on the preparation table 11 and connected to multiple extrusion tubes 32. Each extrusion tube 32 is equipped with a nozzle 33. The function of the nozzle 33 is to control the diameter of the extruded natural plant additive strips.

[0072] For example, if the width of the material surface formed by the powder in the annular groove 121 is 3 mm, the diameter of the material strip of the edible natural plant additive can be controlled to be 0.5-1 mm.

[0073] The nozzle 33 is connected to the extrusion tube 32 in a detachable manner, such as a threaded connection, so as to be replaced when the nozzle 33 is damaged or the diameter of the extruded material strip needs to be adjusted.

[0074] Furthermore, in a direction away from the feeding auger 31 , the flow area in the extrusion tube 32 tends to decrease.

[0075] See also Figure 8 The electric squeezing roller 4 is composed of a bracket 41, a squeezing roller 42, a driving device 43, an annular squeezing belt 44 and a cutting knife 45. The bracket 41 is fixedly mounted on the preparation table 11, and the squeezing roller 42 is mounted on the bracket 41 and is rotatably connected to the bracket 41, and can rotate under the drive of the driving device 43.

[0076] The driving device 43 is installed on the preparation table 11 or the bracket 41. In some possible implementations, the driving device 43 is composed of a motor and a reducer, the motor is connected to the input end of the reducer, and the output shaft of the reducer is connected to the squeezing roller 42 through a coupling.

[0077] A plurality of annular extrusion belts 44 are arranged at intervals on the surface of the extrusion roller 42. Adjacent annular extrusion belts 44 are arranged in parallel and the length of the annular extrusion belts 44 is equal to the circumference of the extrusion roller 42. The number and interval distance of the annular extrusion belts 44 refer to the annular grooves 121, and each annular extrusion belt 44 corresponds to an annular groove 121.

[0078] The annular extrusion belt 44 is also provided with cutting blades 45 at intervals. The cutting blades 45 can be regarded as protrusions on the annular extrusion belt 44. The function of the cutting blades 45 is to cut the strip feed into feed particles. Fig. 9 shown.

[0079] It should be understood that during the production process, the annular extrusion belt 44 will rotate with the extrusion roller 42, and the annular extrusion belt 44 will continuously apply pressure to the raw material in the annular groove 121 to obtain a strip feed. During this process, the cutting blade 45 on the annular extrusion belt 44 will also rotate with the rotation of the annular extrusion belt 44, and the cutting blade 45 will form a dent on the strip feed or directly cut the strip feed. The distance between the two cutting blades 45 is the length of the feed particles.

[0080] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
