Description

Bulking machine and high-predigestion religion groove conservation material equipment comprising same

Technical Field

The utility model relates to a feed processing method, processing equipment and a bulking machine for processing feed, belonging to the field of feed machinery.

Background

In the prior art, creep feed and conservation feed for pig feed and starter feed for chickens are all prepared by a granulating process, and the main characteristic is that the feed is prepared by a granulator.

The main problems of this granulation process are as follows:

(1) the pig feed or chicken feed processed by the process has low curing degree. The feed with low curing degree has low digestion and absorption rate. Directly influences the improvement of the feed conversion ratio of the feed.

(2) Because the temperature of the granulator is lower in the processing process, some inherent anti-nutritional factors and some inherent toxins in the feed raw materials are not completely inactivated in the processing process, the gastrointestinal diseases of the suckling pigs are caused, and the death rate of the suckling pigs is directly improved.

(3) The pulverization rate of the granulated feed processed by the granulator is higher, which directly results in lower feed intake rate of the feed. In the breeding field, the feed residue is high, which causes feed waste. And also brings difficulty to the automatic breeding.

In the prior art, some practitioners have also recognized some of the above disadvantages of feed. The pig feed and the chicken feed are processed by adopting an expansion process or an expansion and granulation process. The new improvement, though, partially solves the above problems. But these problems cannot be solved completely.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is as follows: in order to overcome the defects in the prior art, the utility model provides a bulking machine for feed production and a conservation material device comprising the bulking machine, wherein the bulking machine adopts a double-screw conical constant-pressure mold-blocking-free screw rod, can extrude and bulk a low-moisture material, can stably increase the pressure of the material in the screw, is not unstable in bulking of a conventional bulking machine, the flash evaporation of moisture after the bulking machine reaches 6-7%, and the instant moisture is reduced from 21-22% to 14-15% after the material is demoulded.

The technical scheme is as follows: in order to solve the technical problem, the bulking machine for feed production comprises a bulking shell, wherein an extrusion cavity is formed in the bulking shell, a double-screw rod is arranged in the extrusion cavity and is installed on the shell through a rotating shaft, and an upper discharging port and a feeding port are formed in the shell; the double-screw rod comprises a body, wherein a large spiral groove is formed in the body, and a small spiral groove is formed in the large spiral groove.

Preferably, the upper discharging port is connected with the puffing shell through an upper discharging pipe.

Preferably, the upper discharging pipe is provided with a supporting plate, the supporting plate is provided with two pairs of supporting blocks, the supporting blocks are provided with pulleys, and the supporting plate is provided with a first upper cross beam and a second upper cross beam.

Preferably, the upper discharge port and the feed port are both positioned at the top of the puffing shell.

The utility model provides a high predigestion religion groove child care material equipment, contains foretell bulking machine, and the ejection of compact interface and the airtight quenching and tempering ware of bulking machine are connected, and airtight quenching and tempering ware is connected with pre-processing equipment, and the feed inlet is connected with pneumatic conveying pipe, and pneumatic conveying pipe is connected with reprocessing equipment. In the utility model, a conditioner, a bulking machine and a pneumatic transmission process are adopted, the dryer is removed, the energy consumption is reduced, and the material is directly delivered into subsequent spraying equipment or subsequent cooling equipment from bulking through pneumatic transmission. The method can greatly reduce the production cost and the equipment investment. The main reason why the dryer can be eliminated is as follows: the novel conditioner, the novel bulking machine and the novel pneumatic conveying process ensure that the moisture of the material entering the follow-up equipment reaches 10-12% together. (the moisture content after the puffing in the prior art reaches more than 20 percent, which is the core reason that a dryer must be used.) the novel conditioner ensures that the materials are fully dispersed in a closed area by adopting a sealing structure at two ends and a dense paddle structure in the middle, and then steam and water are input into the area. In the original tempering technology, the temperature of the general materials reaches 100 ℃, the moisture content needs to reach more than 24 percent, and the materials can be fully tempered. By using the novel conditioner, the temperature reaches 100 ℃, and the same conditioning effect can be achieved when the moisture reaches 21-22%. Therefore, the moisture of the novel conditioner can be reduced by 2-3% compared with that of the common conditioner.

The novel bulking machine adopts a double-helix conical constant-pressure mold-blocking-free screw rod. This novel screw rod is compared with ordinary bulking machine, can extrude the material of popped low moisture, can let the pressure of material in the spiral obtain stable promotion in addition, does not have the popped unstability that conventional bulking machine is that kind. More importantly, the flash evaporation of the moisture after the bulking machine reaches 6-7 percentage points, and the instantaneous moisture is reduced from 21-22% to 14-15% after the material is demoulded.

The puffed particles coming out of the puffing machine enter a pneumatic conveying air pipe due to the fact that the puffed particles have high temperature (reaching 80-85 ℃), and are conveyed to subsequent equipment. In the process of pneumatic conveying of the materials, the conveyed air is hot air with the temperature of 30-150 ℃ (adjustable), and meanwhile, one or more material buffering and retaining sections are arranged on the air pipe of the pneumatic conveying so as to increase the retention time of the materials in the air pipe. The moisture of the material in the novel pneumatic conveying air pipe can be reduced by 3-4 percentage points. Therefore, the moisture of the material entering the subsequent equipment (a coating machine or a cooler) reaches 10-11%. Such moisture has achieved safe storage of the moisture, thereby achieving the goal of avoiding the use of a dryer.

Compared with the prior art, the main machine equipment in the process and the equipment disclosed by the utility model uses a novel bulking machine to replace a granulator in the prior art, so that the curing degree, the palatability and the feed intake rate are improved.

The novel bulking machine can greatly improve the curing degree of the feed, and the gelatinization degree of the feed can be improved to 95-100%. The gelatinization degree of the product processed by the granulating process in the prior art is only 30-35%. The improvement of gelatinization degree produces strong cooked flavor on one hand, and the palatability of the feed is greatly improved; on the other hand, the digestibility of the feed is greatly increased, the feed can form predigestion in vitro (nutrients are decomposed in advance in vitro), and the promotion ratio is low. Directly influences the improvement of the feed conversion ratio of the feed. And secondly, the temperature of the puffed particles reaches 110-135 ℃ in the processing process, so that some inherent anti-nutritional factors and some inherent toxins in the feed raw materials are completely inactivated in the processing process, gastrointestinal diseases of the suckling pigs are greatly reduced, and the death rate of the suckling pigs is directly reduced.

Thirdly, since the degree of ripeness is improved, no excessive powder is generated, and all the fodder is formed into granules, the fodder is not wasted. The feed is also suitable for large-scale automatic breeding of farms.

Compared with the prior art, the double-helix conical constant-pressure mold-blocking-free screw is adopted in the bulking machine, and for a common bulking machine, when a high-starch formula is produced, and when small particles with the mold aperture of 1.0-3.0 mm are produced, the material remains, and the extrusion of the material in a bulking cavity is not uniform, so that the following problems are caused: the sizes of the expanded particles are not uniform; secondly, the material easily blocks the die hole, which causes the reduction of productivity and further influences the unevenness of particles.

Adopt neotype technique, double helix toper structure has ensured that the material is stable at the extrusion in-process, and is invariable at same regional internal pressure, and simultaneously at the extruded in-process, pressure progressively steadily promotes. The fluctuation of pressure has been avoided, simultaneously because this structure has the characteristic that the material can not flow back, even the template has blockked up, the material also can break open the nib, lets the nib continue to work, reaches the mesh that the nib is not blockked up.

In addition, due to the extrusion characteristic of the screw, the pressure is higher and the characteristic of sudden instant release is realized, more moisture is flashed compared with a common bulking machine, the flash evaporation of the moisture after the bulking machine reaches 6-7 percentage points, and thus the puffed particles with lower moisture are obtained.

In addition, due to the extrusion characteristic of the screw rod with the structure, when a die with the diameter of 1.0-2.0 mm is produced, the die can be normally produced without using an ultra-power crushing device, and the phenomenon of blocking the die is avoided.

For a conventional bulking machine for producing formed granules, when small granules with the aperture of a die of 1.0 mm-2.0 mm are produced, an ultra-Wei crushing device is required, otherwise, a template is blocked.

Compared with the prior art, the tempering device in the process and the device uses a novel closed type tempering device to replace a common tempering device. The novel conditioner adopts a two-end sealing structure and a middle intensive paddle structure, so that materials are fully dispersed in a closed area, and then steam and water are input into the area. The two ends adopt spiral sealing structures, so that the materials can be ensured to enter the conditioner and leave the conditioner, and meanwhile, the steam in the conditioner can not smoothly leave the conditioner. An intensive small paddle structure is adopted between the closed structures at the two ends of the conditioner, and the rotating speed of the rotor is controlled through variable frequency speed regulation, so that the materials can form a better dispersion state in the area. Steam and water are simultaneously input into the dispersed material in the area, and the material can absorb the steam and the water more easily. Under the condition of reaching the same pre-curing state (generally, the gelatinization degree of the pre-curing is required to reach 40-45%), the temperature of the novel conditioner reaches 100 ℃, and the moisture reaches 21-22%, so that the same conditioning effect of a common conditioner (the temperature is 100 ℃, and the moisture reaches 24%) can be achieved. In addition, the energy consumption is reduced, the pollution of the escaping steam to the environment is avoided, the overflow of dust is reduced, and the requirement of environmental protection is met.

The utility model includes upward pneumatic conveying of the outlet of the bulking machine. Compared with downward pneumatic conveying, the former reduces material accumulation in a short time after the mold stripping of the bulking machine. Because the material at the outlet of the bulking machine is extruded out instantly, the material is in a high-temperature and high-viscosity stage. If the materials are piled up, the moisture of the materials is difficult to be emitted, and the particles are bonded together, so that the moisture of the materials is difficult to reduce.

Set up one or more and detain the section in the middle of air feed's the tuber pipe, the main objective lets popped granule obtain the detention of certain time in this position, lets the better dispersion of granule come simultaneously, lets more steam and granule separate. Pneumatic transport transports the particles upwards. And the upward pneumatic conveying is adopted, so that the materials after the die comes out are dispersed in a short time, more water vapor can leave the particles conveniently, and the bonding and agglomeration among the particles are avoided.

The adjustable hot air temperature means that the purpose of controlling the moisture of finished product particles can be achieved by controlling the temperature of hot air according to the actual moisture condition of the material. In the actual processing, if the moisture is in an allowable state, hot air with a lower temperature can be used, or hot air is not used.

The material firstly enters the whole process flow through a feeding port; then crushing the materials through a crushing section, wherein the fineness of the crushed materials can reach 85 percent and can pass through 60 meshes; then, the ingredients are mixed, and liquid grease can be added in the mixing section; then screening to remove the large impurities in the materials; then entering a tempering and puffing section, and puffing the powder in the section to form high-curing molded particles; then, the expanded formed particles enter a spraying machine through pneumatic transmission, and the surface of the formed particles is sprayed with grease in spraying equipment so as to improve the nutritional ingredients of the feed; then, the formed particles enter a cooler for cooling, and the cooling temperature is reduced to about room temperature, so that the quality guarantee time of the formed particles can be prolonged; then, the formed granules enter a finished product inspection sieve, and in the working section, impurities in the formed granules are cleaned, or residual granules with other specifications are cleaned; finally, the final product is obtained and enters a packaging machine or a feed transport vehicle.

Has the advantages that: compared with the prior art, the method has the following advantages:

(1) the conditioner adopts a structure with sealing structures at two ends and a structure with dense blades in the middle to fully disperse materials in a closed area, and then steam and water are input into the area. In the original quenching and tempering technology, the temperature of general materials reaches 100 ℃, the moisture needs to reach more than 24%, the materials can be fully quenched and tempered, and the temperature reaches 100 ℃ and the moisture reaches 21-22% to achieve the same quenching and tempering effect by utilizing the novel quenching and tempering device. Therefore, compared with the common conditioner, the novel conditioner can reduce the moisture content by 2-3 percent.

(2) The double-helix conical structure is adopted, so that the stability of the material in the extrusion process is ensured, the pressure in the same area is constant, and meanwhile, in the extrusion process, the pressure is gradually and stably increased. The fluctuation of pressure is avoided, and because the structure has the characteristic that the material can not flow back, even the template is blocked, the material can also break the die hole, and the die hole is made to continue working, so that the purpose that the die hole is not blocked is achieved.
