Economics of twin screw extruder machine

In many countries, the existing feed processing is still dominated by single-screw extruders. Although twin-screw extruders have some applications in the feed processing industry, they are much inferior to the food processing industry.

In order to meet the needs of the development of the feed industry, it is necessary to pay attention to the application of twin-screw extrusion technology in feed processing. Why use a twin screw extruder machine instead of a cheaper single-screw extruder for processing specialty feeds?

Economic analysis should not only look at the higher price of twin screw extruders than single screw extruders, but should consider the cost per ton of product produced. With the advent of steam injection, greater efficiencies can be achieved in twin screw extruders.

As a manufacturer specializing in twin screw extruder for sale, Richi Machinery actively promotes the global strategy, cultivates an international business model, and has accumulated rich practical experience. The customer market covers six continents: Asia, Europe, Africa, North and South America and Oceania.

Generally, an extruder with a screw diameter of 80mm can produce 150-200kg per hour; an extruder with a screw diameter of 90mm has a production capacity of 500-800kg per hour; an extruder with a screw diameter of 110mm has a higher production capacity. It can reach 1000-1500kg per hour. Generally, the production cost per ton of feed is about 40USD.

With the emergence of new two screw extruders with high torque, the maximum speed of the screw can reach 1000r/min, or even higher. Where large-scale extruders were required in the past, it may only be necessary to use smaller extruders in the future.

With the application of new materials and new technologies in the twin extruder machine, the wear of the screw will become smaller and smaller. Even if the raw materials with bone meal or other components with greater wear are processed, the service life of the barrel can reach 15,000-20,000 hours.

It can be seen that the twin screw extrusion machine can not only produce more consistent products and more diversified products, but also the double screw extruder with high torque and high speed will generate greater economic benefits.

Application of twin screw extruder in pet feed

—— Richi Machinery ——

“Twin screw extruder in food processing” mainly includes aquatic feed processing and pet feed processing. Let’s talk about twin screw extruder food processing for pet first.

The main components of pet food are generally composed of grain meal (such as wheat flour) and animal meal with high content, fresh meat and fat. In the dry pet feed production process, when the fresh meat content is as high as 20%-30%, intense mixing and kneading are required during extrusion, which can only be accomplished by a twin screw extruder machine. Because of the mutual rubbing and extrusion of the twin screws, even when the raw materials are high in grease, they will not stick together and affect the operation of the twin screw food extruder.

Richi Machinery specialize in twin screw extruder for sale, our twin screw extruder is carefully designed for customers according to the actual requirements of customers, which fully reflects the rationality, effectiveness and applicability of the design, large processing capacity, low wear and operating costs.

small electric fish feed extruder machine price extruder price
extruder pelletizer extruder for feed

Compared with the single-screw extruder, almost twice as much fat can be added to the pet feed in the twin extruder machine, so the feed formula can contain more than 12% fat. This not only improves the quality of the formula, but also slows down the wear and resistance of parts, reducing production costs, which cannot be achieved by a single-screw feed extruder.

In a single-screw extruder, the fat content is limited, because if the fat content is too high, the extruder fluctuates wildly and, therefore, the product quality is unstable. Once the fat content of the feed is too high, it will cause the feed to stick and the machine will not work.

In addition, it can also be used for color identification, because the double screw extruder extrusion can complete the change of raw materials in 30s, which allows the product of multi-color mixture to be processed directly in the double screw extruder machine.

Specialize in twin screw extruder for sale, we have hundreds of twin screw extrusion line projects (completed and under construction), no matter what kind of feed or feed form your raw material is, you are welcome to consult Richi Machinery at any time, I believe our experience can effectively help you with extrusion feed production.

Application of Twin Screw Extruder Machine in Aquatic Feed Production

—— RICHI MACHINERY ——

The biggest feature of the double screw extruder is that the two screws rotate in the same direction and are fully meshed, so it has the function of a positive pressure pump. It can mix various raw materials regardless of their composition, animal protein, fresh meat pulp, fat, high fiber, starch and wet fish residue and other diverse components can be easily processed, suitable for the processing of high-viscosity materials, low-viscosity materials or high-moisture, high-fat formula products.

Double screw extruder machine can be adapted to process a variety of aquatic feeds such as floating, fast sinking and slow sinking, such as fish, shrimp, river eels, crabs, turtles, bullfrogs, ornamental fish and other high-end feeds, etc., all need to use twin screw roller head extruder, especially particle aquafeed (0.5mm ~ 1.5mm in diameter), high-fat aquafeed and feed with small production volume but often changing formula must be produced by double screw machine.

The high-quality twin screw compounder designed and produced by RICHI refers to the co-rotating and fully meshed product with precision manufacturing and technical performance that has reached a certain advanced level. Although twin screw extruder price is higher than that of the single-screw extruder, it is only one third of a similar product price.

RICHI twin screw extruder machine can not only meet the needs of medium and high-grade aquatic feed in the breeding industry, but also achieve a high cost performance. It is the best choice for the aquatic feed processing industry. RICHI twin screw compounding extruder provides low-cost and cost-effective twin-screw extrusion for aquatic feed and food processing enterprises.

As a manufacturer focusing on the twin screw extruder for sale, Richi Machinery firmly believes in being customer-oriented, creating value for customers, and realizing value sharing with customers. It is not a simple verbal promise, but “considering customers as friends” and going deep into the market forefront, deeply understand the problems encountered by customers, and help customers achieve higher value returns.

01 The double screw extruder can adapt to the changes of various raw materials, and has strong adjustability in the production of high-grade aquatic products with large changes in product types

To produce general shrimp feed, a long single-screw extruder can do the job. Short single-screw extruders are often used in the pretreatment of raw materials with a single variety and in the processing of some common feeds that do not require high processing quality.

They have poor adaptability to changes in materials and product requirements. In the production of large-scale aquatic feed or high-grade aquatic feed, attention should be paid to the aspect ratio and adjustability of the extrusion machine screw, so that the quality of the feed produced is good.

animal feed extruder cold feed extruder

Compared with single-screw extruders, twin screw extruder machine can be used in a wider range. Due to the assistance of the two screws, the direction of the material during the extrusion process is ideally controlled to avoid reverse gap flow, the material is balanced in force, the residence time in the machine is consistent, and the product is uniform.

feed pellet extruder force feeder for extruder

Even if the moisture content of the raw material is more than 40% and the oil content is more than 17%, the product with high molding rate can still be obtained. The twin screw compounding machine does not need to set up resistance grooves on the inner wall of the dual screw extruder bore, and there is little material residue in the machine, which is easy to clean up for changing varieties and before shutdown.

To produce high-grade aquatic products or feed raw materials are rich, such as containing high protein, high fat, the moisture range of the raw material is wide, and the diameter of the aquatic product changes greatly, it is more suitable to choose a twin screw compounding extruder.

In addition, when the product type changes greatly, such as the production of floating, sinking and slow sinking feed, the choice of twin screw compounder is more adjustable, and the parameter settings are also easier to change. The compounding twin screw extruder has a complex structure and a relatively high price.

With the improvement of RICHI double screw machine technology and manufacturing level, its production technical performance indicators have approached the level of similar high-end extruder products, with good cost performance. Some aquafeed manufacturers that value processing quality or some often use high moisture content or high-fat raw material feed, often willing to make a larger investment and choose a twin screw extruder for food processing.

02 Single screw and twin screw extruder? the twin-screw extruder has obvious advantages in the production of aquatic feed.

fish extruder machine side feeder extruder

Using different processing techniques and equipment, the quality of the produced aquatic feed pellets varies greatly in terms of bulk density, water resistance, and degree of maturation. Extrusion technology is widely used in aquatic feed production, creating conditions for improving aquatic feed quality, feed remuneration, resource utilization, and water quality improvement.

The structure of the single-screw aqua feed extruder is relatively simple, which affects the processing of high-viscosity and high-oil-containing materials. At the same time, it is very sensitive to high pressure and has poor conveying capacity.

The arrangement of the barrel, screw and thrust bearing gear box of the twin-screw extruder is relatively complicated, which improves the mixing and homogenization of materials during production, and provides better mixing and heat exchange. In addition to the increased investment cost, in addition to the general advantages of single-screw extrusion, it also has the following characteristics:

  • The product is superior to the single screw in terms of quality stability, maturation, water resistance and safety.
  • The process conditions and parameters are easy to adjust, and the product density is easy to control. It can produce feeds that are completely suitable for the needs of aquatic animals and the desires of breeders, including sinking, floating, and semi-sinking extruded pellet feeds, and the product quality is high.
  • It is suitable for a wide range of materials, the fat content can reach more than 17%, and the fresh meat content can reach more than 35%.
  • It has self-cleaning function.
  • The screw has a long service life and low power consumption per unit of output. In short, in the production of aquatic feed, the twin-screw extruder has obvious advantages compared with the single-screw extruder, and will be vigorously promoted and widely used.

Single screw extruder and twin screw extruder, which is better? Compared with the single-screw extruder, the twin-screw extruder has obvious advantages in the production of aquatic feed.

As a manufacturer focusing on the twin screw extruder for sale, Richi Machinery firmly believes in being customer-oriented, creating value for customers, and realizing value sharing with customers. It is not a simple verbal promise, but “considering customers as friends” and going deep into the market forefront, deeply understand the problems encountered by customers, and help customers achieve higher value returns.

For double screw extruder installation and debugging, our company will send technicians to guide the installation and debugging training for free.

03 How to choose twin screw extruder machine for twin screw extrusion line in aquafeed factory?

With the advancement of aquaculture technology, extruded feed has become a demand preference of some farmers. More and more aquafeed mills are also building or rebuilding aquafeed extrusion production lines. At present, most of the twin screw extruders on the market can meet the needs of feed production enterprises, but for some reasons, they have not achieved the expected results after being put into production. Therefore, Richi Machinery believes that several issues should be paid attention to when choosing twin screw extruder in food processing:

  • Clarify the positioning of the feed product and the adaptability of the extruder. Both single screw extruder and twin screw extruder can produce high-quality feed, but twin screw compounding machines have better adaptability and work stability in producing high-fat feed and small pellet feed, and the capital investment is also greater.
  • Most aquafeed mills attach great importance to the strategic competitiveness of small pellet feeds. Therefore, for the extruded feed production enterprises of the planned scale, it is recommended to configure a professional small twin screw extrusion line.
  • The extruder that can produce both floating feed and sinking feed has higher requirements on the equipment and its operation, and it is recommended to be equipped with a density control device.

  • Some countries pay more attention to the appearance of puffed granule products, such as the incision effect. The power configuration of the cutter motor of some screw type extruders is too small, and the rotation speed is preferably configured according to the two-stage motor.
  • The water and steam valves matched with the extruder need to choose first-class products to ensure stable water supply and gas supply during the working process of the screw extruder machine.
  • The extrusion extruders provided by some twin screw extruder manufacturers are not significantly different in terms of unit energy consumption and hourly production capacity, but there is still a gap in particle uniformity and the service life of the screw and screw sleeve, which should be quantified in the screw extrusion machine purchase contract terms of agreement.
  • During screw feed extruder debugging, work with the technical staff of the twin screw extruder suppliers to explore the best operating parameters of their own products, find the best template opening rate and best hourly production capacity suitable for the formula system, and reduce the loss in the whole twin screw extrusion line process.

Our twin screw compounder has been continuously improved in terms of granulation efficiency, processing capacity, reliability, particle shape optimization, energy consumption control, etc., so that its comprehensive performance is more excellent, and it can adapt to a variety of complex working conditions.

Richi Machinery not only focuses on the twin screw extruder for sale, but also have more than 25 years of experience in extrusion feed mill plant design. Richi Machinery’s twin screw extrusion line project has become more mature after nearly two years of operation. The services we can provide include technical assistance in the entire process of extrusion feed production line design, site planning, and process plans. The project manager is responsible for unified tracking, making the project progress and cost input more clear.

Design Of twin screw extrusion line For Feed Processing

Nowadays, countries in the world have stricter and stricter requirements for environmental protection, especially the protection of water quality in aquaculture and the safety and quality of aquaculture products are given top priority. As extruded feed with less impact on water quality and environment, more and more attention has been paid.

According to statistics, 70% of aquatic feed in the United States and 100% of aquatic feed in South Korea are produced by extrusion technology. There are also more and more feed processing enterprises in China gradually replacing traditional pellet mills with extruders to produce aquatic feed and other special feeds.

Process flow of the 8 t/h twin screw food extruder plant

The biological feed of this twin screw extrusion line project is based on soybean meal, corn DDGS, flour, chicken meal, etc. as the main raw materials, together with vitamins, amino acids and minerals and other trace components to make granular feed. The project adopts the process of first crushing and then batching.

The raw and auxiliary materials that need to be crushed (soybean meal, corn DDGS, rice bran) are crushed by a hammer mill feed grinder respectively, and then enter the batching bin, and mixed with other raw and auxiliary materials (fish meal, flour, etc.) that do not need to be crushed. The feed product is produced after mixing, extruding by twin screw extruder machine.

The production process of the extruded fish feed production line and shrimp feed production line in this project is basically the same, except that the feed of the extruded fish feed line needs to be extruded and sprayed with oil, but the ratio of raw and auxiliary materials is different.

Richi Machinery has been closely following the trend of modern industrial design and the general development trend, and constantly innovating and developing new processes and new equipment. We will customize scientific and reasonable aqua fish shrimp feed production processes for you according to your materials, output, extrusion feed plant site and other factors.

01 Raw material receiving, cleaning and crushing section

After the main raw materials required for production are transported into the fish feed factory area by car, after being weighed and inspected by the car scale, they are transported into the raw material workshop and raw material silo through the receiving equipment for storage. After the auxiliary materials required for production are weighed and checked by the truck scale, they are directly sent to the raw material workshop for storage.

The raw materials that need to be pulverized enter the production workshop through the conveying equipment, and then enter the silo to be pulverized after the initial cleaning screen to remove impurities and the permanent magnet cylinder to remove ferrous impurities. After the raw materials in the pulverizing silo are pulverized to the qualified particle size requirements by the pulverizer, they are distributed to the raw material silo by the conveying equipment for storage.

The raw materials that do not need to be crushed enter the production workshop through the conveying equipment, and after the initial cleaning screen to remove impurities and the permanent magnet cylinder to remove ferrous impurities, they are sent to different raw material warehouses by the distributor for storage.

02 Batching and mixing section

According to the requirements of the formula, various raw materials participating in the batching are sequentially fed into the mixer through a computer-controlled batching scale.

In the batching process, two batching scales, one large and one small, are used to ensure the accuracy of batching and shorten the batching time. Some additives, vitamins and other raw materials with less dosage are manually weighed and put into the mixer manually.

force feeder extruder manual food extruder twin screw extruder for sale

All kinds of raw materials are mixed in the mixer. The mixed powder material enters the extruding section to make extruded feed, and the feed that does not need to be puffed by double screw machine enters the pelletizing section.

03 Puffing, drying, spraying section

The prepared, mixed and finely powdered materials first enter the to-be-expanded bin for processing. When working, the feeder feeds the material in the to-be-expanded bin uniformly and continuously into the dual-shaft differential conditioner for conditioning. of steam, water and other liquid additives. After a certain conditioning time in the conditioner, the material enters the feeding section of the double screw extrusion assembly to start the extrusion operation, and the material is input from the feeding section.

The main function of the feeding section is to transport the material to the kneading area and compress the material initially; in the kneading section, the material undergoes intense stirring, mixing, shearing, etc., the material is gradually cooked or melted; it enters the final curing section. The pressure and temperature are further increased, the material is further matured, the starch is further gelatinized, the fat and protein are denatured, the tissue is homogenized and an amorphous texture is formed, and the final material is extruded and cut through the discharge assembly.

pet food extruder twin screw extruder china

The puffed feed enters the dryer through the air transport system, and the steam heated air is used as the drying medium. The air realizes the exchange of moisture and heat in the dryer, so as to remove the excess moisture in the material and make it meet the moisture requirements of the finished product. Finally, the surface of the pellet feed is sprayed with oil, vitamins, antioxidants, amino acids and other liquids in batches by the spraying machine.

04 Measurement and packaging of finished products

Finished product packaging is the last step in feed processing. There is a packing scale installed under the finished product warehouse. The packing scale automatically quantitatively packs according to the quantity set by debugging, and then the bag mouth is sewed by the sewing machine to complete the double screw extrusion process.

Fish feed Production Process flow of the 25 t/h twin screw feed plant

01 Feeding of raw materials

The raw materials are transported to the feeding port for feeding by the elevator, and the feeding dust is generated in this process. The feeding dust is collected and processed and reused in the raw material feeding process;

twin screw extruder manufacturers extruder for sale in south africa

02 Raw material cleaning

The packaging raw materials such as flour, fish protein, and sub-flour have completed the raw material cleaning process during the raw material production process, and generally no longer need to be cleaned. Soybean meal, rapeseed meal and other raw materials are often mixed with some impurities such as sand, dander, straw, etc.

The existence of a small amount of impurities has a great impact on the quality of the finished feed, and it is necessary to clean up the impurities before production. The fish feed raw material cleaning process is mainly to screen and remove impurities from soybean meal and rapeseed meal.

03 First pulverization

The raw materials need to be coarsely pulverized by a hammer mill feed grinder, so that the components can be mixed evenly, and the automatic classification after mixing is reduced. The pulverized materials are transported through pipelines to the next process. The material is collected by the pulse bag filter, and the separated material is collected by the pulse bag filter, and the material directly enters the next process.

04 First batching

It is mainly for the preparation of materials with a large proportion in the formula. Each material is equipped with a batching scale under the batching bin, and each material is weighed by the batching scale and then sent to the mixer for mixing by the conveyor.

hand poultry fish feed extruder machine extruder machine price twin screw extruder for sale

05 Secondary crushing

Due to the low feed intake, short digestive tract and poor digestion ability of aquatic animals, aquatic feed requires very fine crushing particle size to increase the surface area of ​​the feed and improve the digestibility of the feed and feed remuneration for aquatic animals.

At the same time, due to the low intake of aquatic animals, the mixing uniformity of the feed is required to be improved in a smaller range, which also requires the feed to have a finer particle size.

The raw materials after one mixing are processed by ultra-fine pulverizer, equipped with powerful wind separation equipment, and then enter the rotary grading screen for screening to remove the fine fluff formed by the coarse fibers in the feed during the pulverization process, and the material enters the next process.

06 Secondary batching

After each material is weighed by the batching scale, it is sent to the mixer by the conveyor for mixing, and trace additives are mainly added in this process. (Related post: animal feed mill plant)

07 Extrusion of fish feed

The mixed semi-finished product enters the twin screw extrusion machine, is heated and sterilized by high-temperature steam, pressurized, and then extruded out of the die hole, and then suddenly depressurized to rapidly vaporize the water molecules inside, so that the material expands and becomes extruded pellet feed.

pelletizing extruder extruder pelletizing machine

08 Drying

After the feed is expanded by twin extruder machine, it needs to be dried with an extruded fish feed dryer. The material is continuously turned forward and backward in the rotating drum and gradually dried. The temperature is about 40~50 °C, and a small amount of odor is generated during the turning process.

09 Oil injection

Fish have limited ability to utilize sugar, and their energy sources are mainly provided by the decomposition of fat and protein. energy value.

10 Cooling

After the feed oil is sprayed, a counter-current flap cooler is used for cooling. (Related post: aqua feed mill equipment)

11 Screening

The cooled feed enters the grading screen for classification, the finished product enters the packaging process, and the screened scraps are reused in the raw material feeding process;

12 Packaging

The finished product is packaged by the workers using the packaging machine to leave the aqua extrusion fish feed factory.
