Dry Feed Extruder
Ideal for simplifying processes, saving energy and creating high-quality feeds for livestock

Dry Feed Extruder Overview
Dry feed extruder is a kind of feed extruder that processes raw materials into pellets or expanded feed suitable for animal digestion through high temperature, high pressure and mechanical shear action. Dry extrusion technology eliminates the need to add steam or water, simplifying the production process while reducing energy consumption.

Working Principle of Dry Feed Extruder
Main Components and Working Principle
Feeding System
Equipped with high efficient automatic feeding device to ensure that the raw materials enter the extrusion chamber evenly, avoiding blockage or uneven supply of raw materials and ensuring production stability.
Mold and Cutter
The raw material is formed in the extrusion chamber and then extruded through the die. The cutter adjusts the length and shape of the pellets according to the demand to ensure the diversity and uniformity of the finished products.
Exhaust System
The gas generated during the extrusion process is discharged through the exhaust holes, preventing the gas from accumulating and affecting the extrusion efficiency, and at the same time enhancing the density and texture of the finished feed products.
Screw extrusion system
The screw made of high-strength alloy material mixes, shears and extrudes the raw materials, and makes the raw materials under high temperature and high pressure undergo physical and chemical changes.
Heating System
The raw material is efficiently heated by an electric heating device to achieve the high temperature environment required for dry extrusion, without the need to add additional steam, saving energy.
Discharge and Cooling System
Finished pellets are discharged through the discharge port and enter the cooling device, which rapidly reduces the temperature and improves the hardness of the pellets for subsequent packaging and storage.
Features and Advantages of Dry Feed Extruder
Features and Advantages
Nutrient Retention
The high temperature extrusion process removes anti-nutritional factors from raw materials while retaining their nutrients, improving palatability and digestibility.
Energy Savings
Dry extrusion eliminates the need for additional steam or water, simplifying equipment configuration and significantly reducing energy consumption.
Adaptable
The equipment supports the processing of a wide range of raw materials, including grains, beans, fish meal, etc., which is suitable for the different needs of livestock and poultry and aquatic feeds.
Convenient operation
Equipped with advanced control system, it supports automated operation, reduces manual intervention, and is suitable for a wide range of raw material processing.

Dry Feed Extruder Application Scenarios
Application Scenarios
Livestock feed production
It is used in the production of livestock feed for pigs, cows, sheep and other livestock, providing high nutrition and high energy pellet feed to meet the rapid growth needs of livestock.
Poultry feed processing
For the production of poultry feed for chickens, ducks, geese, etc. The pellet size is uniform, which improves feed palatability and feeding efficiency, and is widely used in poultry farms.
Aquatic feed manufacturing
Especially suitable for the production of fish, shrimp and other aquatic animal feed, extruded pellets can float or sink, to meet different aquaculture needs.
Pet food production
The production of pet food for dogs and cats, etc. The pellets have a uniform texture, are easy to digest, and can meet the high nutritional needs of pets.

Frequently Asked Questions.
Usually around 120% – 250%, the exact value depends on the characteristics of the raw material, such as the fiber content of the material, the proportion of starch, as well as the temperature, pressure, screw speed and other factors set by the equipment.
Through the precise temperature control system, the heating temperature can be set flexibly from 90 to 220℃, combined with the appropriate screw speed and material residence time, to promote the starch to be fully pasted, and then precisely control the degree of maturity of the products.
Adjustments can be made midway through the process, but fine-tuning is recommended. Sudden and drastic changes in parameters such as temperature and pressure may lead to an unstable state of expansion of the material, affecting the appearance, texture and internal structure of the product, whereas gradual adjustments can minimize the negative effects.
The main differences are capacity, power, component size and durability. Large equipment has high power to drive high-intensity production and high output; thick and durable parts to cope with large workloads; while small equipment has a small footprint, low energy consumption and flexible operation, which is suitable for small batch requirements.
The ideal water content is 8%-15%. If the water content is too high, the material will be easily caked and clogged at the screw, which will affect the expansion; if the water content is too low, the material will be too dry, which may lead to uneven expansion and the product will be easy to be broken.
There are requirements, the raw material should be crushed to 1 – 8 mm, which is conducive to the smooth pushing and full extrusion of the screw, too large particles will easily lead to poor extrusion and incomplete expansion, while too small particles will be easy to raise dust, and the feeding is not smooth.
