15 Steps to Choose the Right Feed Extruder for Your Production Needs




The feed industry is highly competitive. In order to be able to produce feed at a lower cost, feed production companies need to invest in the right technology. One of the most important pieces of equipment in feed production is the extruder. The right extruder can make a big difference in terms of product quality and production costs.


When it comes to feed extrusion technology, feed production companies have a number of factors to consider. The most important criteria for making the right choice of extruders include feedstock, product quality, and production capacity. In this blog post, we will discuss the most important factors that need to be taken into account when choosing an extruder for your feed production needs.

The feed industry has relied on extrusion technology for many years now. The process of feed extrusion has been very important in the development of the feed industry and there are plenty of variables playing a role in the consistent product quality when it comes to extrusion. Feed production companies need to follow a number of steps to make a conscious choice of what makes the difference in the choice of extruders. Below are the 11 most important criteria feed production companies should consider when choosing feed extruders:

  • The type of feed (pelleted, crumbles, or textured)

  • The capacity requirements

  • The desired pellet size

  • The die configuration

  • The feed rate

  • Screw design

  • Barrel configuration

  • Motor size and power requirements

  • Cooling system

  • Lubrication system

  • Electrical control system

  • Dust collection system

  • Spare parts

  • Maintenance

  • Service and support

With so many different types of feed extruders on the market, it can be difficult to decide which one is right for your feed production needs. But by taking the time to consider all of the important criteria, you can be sure to choose the feed extruder that will best meet your needs.


The Type of Feed (Pelleted, Crumbles, or Textured)

The first step in choosing the right feed extruder is to determine the type of feed that you will be producing. Are you looking to produce pelleted feed, crumbles, or textured feed? Each type of feed has its own unique set of requirements, so it's important to know which type of feed you'll be producing before making a decision on which feed extruder to choose.


If you're looking to produce pelleted feed, you'll need to choose a feed extruder that is specifically designed for pellet production. These types of feed extruders typically have a die with multiple holes, which helps to create the pellets. They also often have screws with spiral grooves, which help to move the feed through the extruder and create a consistent pellet shape.


If you're looking to produce crumbles, you'll need to choose a feed extruder that is specifically designed for crumble production. These types of feed extruders typically have a die with fewer holes than those used for pellet production. This helps to create smaller, crumb-like pieces of feed. They also often have screws with helical grooves, which help to move the feed through the extruder and create a consistent crumble shape.


If you're looking to produce textured feed, you'll need to choose a feed extruder that is specifically designed for texture production. These types of feed extruders typically have a die with unique shapes that help to create the desired texture. They also often have screws with different designs, which help to create the desired texture in the feed.

Capacity Requirement

The capacity is another important criterion to consider when choosing a feed extruder. The capacity is the amount of feed that the extruder can hold. The larger the capacity, the more pellets can be produced per hour. However, if the capacity is too small, it can cause the pellets to be of poor quality.


How much feed do you need to produce on a daily or weekly basis? The answer to this question will help you determine the size and capacity of the feed extruder that you need.

If you have a small operation and only need to produce a few tons of feed per day, you can choose a smaller feed extruder. These feed extruders typically have a lower capacity and may not be able to produce as much feed per hour as their larger counterparts. However, they are typically less expensive and can be a good option for small operations.


If you have a large operation and need to produce many tons of feed per day, you will need to choose a larger feed extruder. These feed extruders typically have a higher capacity and can produce more feed per hour than their smaller counterparts. However, they are typically more expensive and may not be the best option for small operations.


The Desired Pellet Size

Another important criterion to consider when choosing a feed extruder is the desired pellet size. What size pellets do you need to produce? The answer to this question will help you determine the die size that you need.


If you need to produce small pellets, you will need a feed extruder with a small die. These feed extruders typically have a small die size and can produce pellets that are less than one inch in diameter. However, they may not be able to produce larger pellets.


If you need to produce large pellets, you will need a feed extruder with a large die. These feed extruders typically have a large die size and can produce pellets that are more than one inch in diameter. However, they may not be able to produce smaller pellets.



The Die Configuration

The die configuration is another important criterion to consider when choosing a feed extruder. There are two main types of die configurations: single-hole and multi-hole.


Single-hole dies are typically used for lower capacity feed production, while multi-hole dies are more commonly used in high-capacity feed production. The number of holes in the die will also play a role in the feed product's final density and expansion.


If you need to produce pellets that are all the same size, you will need a feed extruder with a single-hole die configuration. These feed extruders have a die with only one hole, which helps to produce pellets that are all the same size.


If you need to produce pellets that are of different sizes, you will need a feed extruder with a multi-hole die configuration. These feed extruders have a die with multiple holes, which helps to produce pellets that are of different sizes.


The die size is the last criterion to consider when choosing a feed extruder. The die size is the diameter of the hole in the die. The larger the die size, the more feed can be produced per hour.


However, if the die size is too large, it can cause the pellets to be of poor quality. The die size should be just right so that the pellets are of good quality and the feed production rate is high.


Screw Design

Another important criterion to consider when choosing a feed extruder is the screw design. There are two main types of screw designs: single-screw and twin-screw.


If you need to produce pellets that are of uniform size and shape, you will need a feed extruder with a single-screw design. These feed extruders have a screw with only one spiral, which helps to produce pellets that are of uniform size and shape.


If you need to produce pellets that are of different sizes and shapes, you will need a feed extruder with a twin-screw design. These feed extruders have a screw with two spirals, which helps to produce pellets that are of different sizes and shapes.


Feed Rate

The feed rate is another important criterion to consider when choosing a feed extruder. The feed rate is the speed at which the feed is moved through the extruder. The faster the feed rate, the more pellets can be produced per hour. However, if the feed rate is too fast, it can cause the pellets to be of poor quality.



Barrel Configuration

The barrel configuration is the next criterion to consider when choosing a feed extruder. There are two main types of barrel configurations: single-stage and multi-stage.


The single-stage barrel is the most commonly used in feed extruders. It is simple and efficient. The multi-stage barrel is more complex but it offers more control over the process.


Nozzle Configuration

The nozzle configuration is another criterion to consider when choosing a feed extruder. There are two main types of nozzle configurations: die-face and vented.


Die-face feed extruders have a die with numerous small holes, through which the feed mixture is extruded. The vented feed extruder has a die with one or two large vents that allow steam and other gases to escape from the feed mixture.


The choice of nozzle configuration depends on the type of feed being produced. For example, pelleted feed requires a die-face feed extruder, while crumbles or pellets require a vented feed extruder.


Pelleted feed is made by passing the feed mixture through a die with numerous small holes. The pellets are then cut to the desired length and cooled.


Crumbles are made by passing the feed mixture through a die with one or two large vents. The crumbles are then cooled and dried.


The vented feed extruder is the most common type of feed extruder used in feed mills today. It is used to produce a variety of feed products, including pellets, crumbles, and flakes. The vented feed extruder is also the most versatile feed extruder, as it can be used to produce a wide variety of feed products.


The die-face feed extruder is less common than the vented feed extruder, but it is still used in some feed mills. The die-face feed extruder is used to produce pelleted feed. Pelleted feed is made by passing the feed mixture through a die with numerous small holes. The pellets are then cut to the desired length and cooled.


Motor Size and Power Requirements

There are a number of criteria that need to be considered when choosing an extruder. The first criterion is the motor size and power requirements. The feed industry uses a variety of feedstocks, including corn, soybeans, wheat, and barley. The type of feedstock will dictate the size and power requirements of the extruder.


Pellet Size

The pellet size is the last criterion to consider when choosing a feed extruder. The pellet size is the diameter of the pellets that are produced by the feed extruder. The larger the pellet size, the more feed can be produced per hour. However, if the pellet size is too large, it can cause the pellets to be of poor quality.


The pellet size should be just right so that the pellets are of good quality and the feed production rate is high. The feed extruder that you choose should be able to produce the pellet size that you need.

Pellet Quality

The quality of the pellets is important because it affects the feed conversion rate. The feed conversion rate is the amount of feed that an animal eats divided by the weight gain of the animal.


If the feed conversion rate is low, then it means that the animals are not getting enough nutrients from the feed. The pellet quality is affected by the ingredients in the feed, the pellet size, and the die size.

The pellet quality also depends on how well the feed is cooked. The feed should be cooked evenly so that all of the pellets are of the same density. If some of the pellets are undercooked, then they will be lighter and will float in water. This can cause the feed to be of poor quality and can lead to clogging in the feeders.


The Cooling System

The cooling system is the next criterion to consider when choosing a feed extruder. There are two main types of cooling systems: air-cooled and water-cooled.


Air-cooled feed extruders are typically less expensive than water-cooled feed extruders. However, air-cooled feed extruders require more maintenance than water-cooled feed extruders.


Water-cooled feed extruders are more efficient than air-cooled feed extruders.

The decision between an air-cooled feed extruder and a water-cooled feed extruder depends on the specific needs of the feed production company.


If cost is the primary concern, then an air-cooled feed extruder may be the best option. If efficiency is the primary concern, then a water-cooled feed extruder may be the best option.

The cooling system is an important criterion to consider when choosing a feed extruder.


The type of cooling system (air-cooled or water-cooled) will impact the cost and efficiency of the feed extruder. The specific needs of the feed production company will determine which type of cooling system is best.


The Lubrication System

The lubrication system is the next criterion to consider when choosing a feed extruder. There are two main types of lubrication systems: oil-based and grease-based.


Each system has its own advantages and disadvantages that need to be considered.


Oil-based lubrication systems are typically used for feed extruders with higher capacities. They require less maintenance and are less likely to cause wear on the parts of the extruder.


Grease-based lubrication systems are generally used for feed extruders with lower capacities. They are easier to maintain and typically provide better lubrication for the extruder parts.

Electrical Control System

The next criteria to consider when choosing a feed extruder is the electrical control system.

There are two main types of electrical control systems: programmable logic controllers (PLCs) and computer numerical control (CNC).


PLC is more common in feed extrusion because it is less expensive and easier to operate. CNC is often used in feed production lines that are automated or have a higher degree of customization.


The electrical control system should be able to meet the specific needs of the feed production line. For example, if the feed production line is automated, the electrical control system should be able to interface with the automation system.


Dust Collection System

Another criterion to consider when choosing a feed extruder is the dust collection system. Dust collection is important in feed extrusion because it can help improve the quality of the feed and prevent cross-contamination.


There are two main types of dust collection systems: cyclonic and baghouse.


Cyclone dust collectors are typically used for smaller feed extruders, while baghouse dust collectors are more common for larger feed extruders.


Cyclone dust collectors work by using a vortex to separate the dust from the air. The dust is then collected in a filter bag or container. Cyclone dust collectors are typically less expensive than baghouse dust collectors, but they also have lower efficiencies.


Baghouse dust collectors work by using a fabric filter to trap the dust from the air. The dust is then collected in a container. Baghouse dust collectors are typically more expensive than cyclone dust collectors, but they have higher efficiencies.


When choosing a feed extruder, it is important to consider the type of dust collection system that will be most effective for your needs.


Operational Requirements


Spare Parts

Another important criterion to consider when choosing a feed extruder is the availability of spare parts. When feed production companies are looking for an extruder, they need to be sure that they can find the spare parts they need in case of an emergency.


Spare parts can be difficult to find for some feed extruders, so it is important to check with the manufacturer before making a purchase.


It is also important to consider the cost of spare parts when choosing an extruder. Some feed extruders may have high-quality parts that are more expensive to replace, while others may have lower-quality parts that are less expensive to replace.


Feed production companies need to be sure that they are getting a feed extruder with high-quality parts. This will ensure that the feed extruder lasts longer and produces a higher quality product.


Maintenance


Another important criterion to consider when choosing a feed extruder is the maintenance required. Feed production companies need to be sure that they can keep their feed extruders running smoothly and efficiently.


Some feed extruders require more maintenance than others, so it is important to check with the manufacturer before making a purchase.


It is also important to consider the cost of maintenance when choosing an extruder. Some feed extruders may require more frequent or expensive maintenance than others.


When considering the cost of maintenance, it is important to balance the frequency and cost of maintenance with the overall quality of the feed extruder.


Service and Support

In addition to quality parts, feed production companies also need to consider service and support. It is important to choose a feed extruder manufacturer that offers good service and support. This will ensure that if there are any problems with the feed extruder, they will be able to help you solve them.
