Today Richi Machinery will share you a business plan of 18t/h poultry pig feed mill and 2t/h expanded corn production line project in China, this is a customized poultry pig feed factory project with 18 tons per hour, there is also a small expanded corn production line added. This 20t/h animal feed factory project was completed in 2018 and is now running well.
Complete feed is also called pellet feed, which can be fed directly without reprocessing. The complete feed is composed of protein feed (such as fish meal, beans and meal, etc.), energy feed (such as corn, wheat bran, etc.), rough feed (used only in low-standard batches) and additives (excluding grain and its supplements). Additives other than the product are called additives) a four-part compound feed. This type of feed product is also called a complete ration compound feed. It is usually divided into various models according to the feeding object (animal type, age, production purpose, etc.).
This kind of feed can fully meet the nutritional needs of the feeding objects, and the user does not need to add any additional nutritive feeding materials, but must pay attention to choosing a full-price compound feed that is consistent with the feeding objects. The feed contains energy, protein, mineral feed and various feed additives. The various nutrients are complete, sufficient in quantity, and proportioned to meet the production needs of feeding animals. It can be directly used for production and generally any other feed does not need to be supplemented.
Expanded corn is also called expanded corn flour, which refers to the starch paste of corn under the combined effects of moisture, heat, mechanical shear, friction, kneading and pressure difference. It can be used as the main raw material for food and feed. Expanded corn has a loose, porous and uniform structure. , The texture is soft and the starch gelatinization degree is improved. It not only has good color, aroma and taste, but also improves the nutritional value and digestibility. It can especially improve the weaning stress problem of young animals. Therefore, the use of puffed raw materials It is an effective way to promote the growth of piglets.
In view of the large market potential of full-price feed and expanded corn, combined with its own capital and technical advantages and the advantages of human resources around the project area, the client company decided to invest in the construction of an annual feed and expanded corn project.

8. Complete 2t/h extruded corn and 18t/h pig poultry feed mill production process
This project is a feed and expanded corn production project. The products are full price feed and expanded corn. The raw material of expanded corn is corn; the raw material of full price feed is corn, soybean meal, corn germ meal, stone powder, calcium hydrogen phosphate, methionine, salt, soybean oil, DDJS, etc.; the main production process is as follows:
(1) Production process of expanded corn
①Receipt of raw materials
Bulk corn and other raw materials are mainly received by automobile, and the raw materials are unloaded to the unloading pit after being weighed by a dump truck with a loadometer.
Impurities in feed ingredients such as corn not only affect the quality of feed products, but also directly affect feed processing equipment and personal safety. In severe cases, the entire equipment can be damaged and affect the smooth progress of feed production, so it should be removed in time. The cleaning equipment is mainly screening. According to the difference in particle size, width, thickness, etc. of the material particles, one part of them will pass through the sieve surface to become the under-sieve, and the other part will remain on the sieve surface as the over-sieve, thereby making feed and impurities Separation, to achieve the purpose of removing impurities, or to separate feeds of different sizes and shapes for classification processing. The screening equipment removes large and long sundries such as straw, straw, hemp rope, paper pieces, soil blocks, corn leaves, corn cobs and other sundries in the raw materials. The screening process is completely airtight, and the screening materials are lifted into the silo.
The screened raw materials are lifted by a hoist into the silo, and a dust filter device is installed on the top of the silo, and the dust generated by the falling of the material during the lifting process is filtered by the filter device.
The corn kernels in the warehouse to be crushed enter the crusher through the impeller feeder. Two crushers are installed in this process. Work efficiency: part of the crushed corn enters the extruder to produce expanded corn, and part of the corn and soybean meal and other materials enter the large crusher to be further crushed to produce full-price feed.
The method of corn puffing in this project is wet puffing. Corn puffing is a starch gelatinization process under the combined effects of moisture, heat, mechanical shear, friction, kneading and pressure difference. The corn puffing heat source of this project is the steam produced by the natural gas steam boiler. When the corn flour is mixed with steam, the starch particles begin to absorb water and expand. When passing through the puffing cavity, the rapidly rising temperature and the kneading of the spiral blades accelerate the absorption of water by the mesh bag starch particles. , The crystal structure begins to disintegrate, the hydrogen bond breaks, and the expanded starch grains begin to rupture and become a viscous melt.
Due to the instantaneous pressure drop at the exit of the extruder, the instantaneous loss of steam (moisture) makes a large amount of expanded starch The granules disintegrate and the starch gelatinizes. High temperature, high pressure and mechanical shearing make the starch gelatinization more thorough than the starch produced by other processing methods. Generally, the gelatinization degree can reach 80%-100%. Compared with the conventional cooking process, the plant cell wall can be broken. The starch chain is shorter, which improves digestibility more effectively. There are many factors affecting corn puffing, mainly moisture, puffing temperature, puffing pressure difference and mechanical shearing force in the cavity.
⑥ Cooling of extruded material
In the puffing process, the high temperature and high humidity steam is introduced and the material is extruded to generate a lot of heat, which makes the temperature and humidity of the puffed particles higher. Under such conditions, adhesion and mildew will occur during temporary storage. The moisture must be reduced to below 14%, and the temperature must be lowered to below 8°C higher than the air temperature. Air cooling is used for project cooling. The extruded material is cooled by the air sent by the fan. The moisture and dust generated during the cooling process are passed through Shakron. The dust collector is discharged outside after treatment.
The extruded material in the warehouse to be crushed enters the crusher through the impeller feeder, and the crushed pellets are conveyed by the screw conveyor and lifted to the temporary storage warehouse by the bucket elevator. This process is equipped with 2 pulverizers, and the particle size after pulverization is about 2-3mm. The purpose of pulverization is to increase the specific surface area of the feed, increase the utilization rate of the animal to the feed, increase the contact area of digestive enzymes to the raw material, and reduce the animal's intake The energy consumption of mastication in the process is beneficial to increase the feed reward; the material is crushed with a crusher and then sieved, and the sieved material is returned to the original crusher for crushing again.
The finished product is transported to the finished product temporary storage warehouse, and then measured and packaged by the baler. The finished product warehouse is airtight. Because the expanded corn product is pellets, the pellet packaging process generates less dust.
(2) Small material/premix feed production process
Stone powder, dicalcium phosphate, methionine, salt and other small materials are transported to the next step through the feeding port through the scraper.
② Ingredients and mixing
Ingredients refer to the various ingredients of the feed formula, which are mixed according to the specified weight ratio, and processed so that every small part of the whole, even a feed, has the same ingredient ratio as the formula requires. This project uses a high-efficiency mixer, with a short mixing cycle, and the coefficient of variation of mixing uniformity is less than or equal to 5%. The materials enter the mixer after being accurately configured by weighing according to the scientific formula. After a reasonable and scientific mixing time, the materials enter the baler after being evenly mixed.
In order to facilitate the subsequent production of ingredients, the evenly mixed small materials are measured and packaged by the baler.
(3) Production process of complete poultry pig feed
★Soybean meal, crushed corn, corn germ meal, DDJS and other raw materials are input through the feeding port, and then conveyed by a screw conveyor, and the bucket elevator is lifted to the next step.
★After the small materials are put in through the powder feeding port, they are conveyed by a screw conveyor and lifted by a bucket elevator to the next step.
★Soybean oil, etc. are directly transported from the storage tank to the batching process;
The pellets in the silo to be crushed enter the pulverizer through the impeller feeder, and the crushed pellets are conveyed by the screw conveyor and lifted to the batching silo by the bucket elevator. The purpose of crushing is to increase the specific surface area of feed, improve the utilization rate of feed by animals, and increase the effect of digestive enzymes on raw materials.
The contact area is reduced; the energy consumption of chewing during the feeding process of the animal is reduced, which is beneficial to increase the feed remuneration; the quality of the subsequent processes is improved and the work efficiency is improved.
③ Ingredients and mixing
Ingredients refer to the various components of the feed formula, which are mixed according to the specified weight ratio, and processed so that each small part of the whole, even a feed, has the same component ratio as the formula requires. When batching, the materials and small materials are mixed in a certain proportion, and the batching accuracy is less than 0.3%. Using a high-efficiency mixer, the mixing cycle is short, and the mixing uniformity variation coefficient is less than or equal to 5%. According to the scientific formula, the materials enter the mixer through a microcomputer and weighing accurately. After a reasonable and scientific mixing time, the microcomputer controls the material to enter the silo to be granulated through the buffer bucket, scraper conveyor, bucket elevator, and distributor.
④Extrusion and granulation
Before entering the animal pig poultry feed pellet making machine, it needs to be tempered. The tempering must be steamed into the material to directly contact and mix and moisten the material. After the tempering is uniform, it will drop to the granulator for granulation by extrusion. The granular feed formed by compacting and extruding a single raw material or compound mixture through mechanical action is called pelleting. The purpose of pelleting is to make finely divided, dust-prone, poorly palatable and difficult-to-ship feed into pellets using the heat, moisture and pressure during the pelleting process.
Compared with powdered feed, pelleted feed has the following advantages: improve feed digestibility; reduce animal picky eaters; make storage and transportation more economical; pelletizing generally increases the bulk density of powdered feed by 40% to 100%; avoids feed ingredients Automatic grading, reducing environmental pollution; killing Salmonella in animal feed. The steam is provided by a natural gas-fired boiler.
During the pelleting process, the high temperature and high humidity steam is introduced and the material is extruded to generate a lot of heat, so that when the pellet feed comes out of the pelletizer, the water content reaches 16%-18%, and the temperature is as high as 75℃ -85. ℃, under this condition, the pellet feed is easy to deform and break, and it will also cause adhesion and mildew during storage. The moisture must be reduced to below 14%, and the temperature must be lowered to below 8℃ higher than the air temperature. The project is cooled by wind Cold, the dust generated during the cooling process is discharged outside after being treated by the cyclone dust collector.
After the pellet feed is processed by the crushing process, a part of powder clots and other unqualified materials will be produced. Therefore, the crushed pellet feed needs to be sieved into products with neat particles and uniform sizes. The finished granular material is conveyed to the grading screen by the elevator, and the grading screen is a two-layer screen. Large sundries, primary products and other large particles on the sieve are collected through the trash discharge port and recycled to the cooling process. The intermediate sieve is the qualified finished product through the flow tube to the finished product warehouse, and the powder and other small particles under the sieve Reflux directly to the granulation process. This process is all airtight. After being concentrated and mixed, the powdered feed product enters into the powder sieve for screening, the oversieve returns to the crushing process, and the undersieve enters the finished product warehouse as qualified products. This process is all airtight.
The finished product is transported to the finished product temporary storage warehouse, and then is packaged and metered and packaged. The finished product warehouse is airtight. Because the powder and fine materials have been screened during the screening process, the amount of dust generated during the packaging process of the pellets is small.
