Dog Food Extruder Machine Structure
RICHI dog food extruder machines can use a PLC and touch screen control system. They feature stable cooking, strong formula compatibility, low energy consumption, and long service life. These features come from the coordinated work of core components.
Variable Frequency Feeder
By controlling the feed rate through frequency conversion speed regulation, continuous and uniform feeding can be achieved, ensuring stable production of the dog food extruder.
Conditioner
An essential component of wet processing technology, enhancing the gelatinization of dog food ingredients and improving dog food quality.
Screw
It functions to push, shear, and squeeze, promoting material maturation and pressurization to ensure rapid shaping after extrusion.
Motor
It is the power source for the whole dog food extruder machine. It lets key parts such as the screw run efficiently and stably.
Blade
It can rotate at high speed along with the main shaft, cutting the extruded material into uniform pellets of uniform length.
Head Flange
Used to lock and fix the forming template, it can withstand the high temperature and pressure in the puffing cavity and prevent material from overflowing.

Highly Adaptable
Dog Food Production Process
How can we make high-quality dog food? It’s not something that can be achieved with just one extrusion process. The complete dog food production process can be broken down into the following steps.
01.
Cleaning
Remove sand, stones, iron filings, packaging ropes, and other debris and foreign objects from dog food raw materials. This ensures dog food purity from the source. It helps eliminate dog food safety hazards. It also protects downstream processing equipment.
02.
Grinding
Grind raw materials such as corn and meat meal evenly into fine powder. The purpose is to increase the surface area of materials. This helps improve mixing. It also improves cooking when wet conditioning is used. It improves digestibility and absorption.
03.
Mixing
The various raw materials, after being crushed, need to be thoroughly mixed and stirred in a certain proportion so that the nutrients can be evenly distributed in each kibble.
04.
Extruding
The mixed materials enter the extrusion stage. Under extrusion and shearing, the materials are instantly extruded and shaped. The high temperature generated during this process kills harmful bacteria. It improves dog food safety.
05.
Drying
The puffing stage in wet processing creates extra moisture inside the dog food. Drying can reduce moisture content. It prevents mold and spoilage. It extends the shelf life of dog food.
06.
Cooling
Quickly cool the dog food pellets after high-temperature drying. Keep the temperature within room temperature range. This can prevent residual heat from causing oil oxidation and rancidity. It improves the hardness and shape stability of dog food pellets.
07.
Spraying
This step can spray and coat the surface of dog food with oil, fish oil, flavorings, or heat-sensitive probiotics. The purpose is to improve pellet palatability and supplement the nutritional content of dog food.
08.
Screening
By using screening equipment, the broken powder and clumps in the dog food pellets are sieved out, leaving only pellets of uniform size and shape, which can effectively ensure the appearance of the dog food.
09.
Packing
This is the last step in dog food production. If you want to reduce labor costs, you can use special packaging equipment. It accurately weighs, packages, and seals qualified dog food. This makes later storage, transportation, or sales easier.

FAQ
Below are some common questions. If you are learning about dog food extruder machines for the first time, or if you have other questions about our products, you may find answers below. You can also contact us directly to learn more about dog food extrusion machines.
What raw materials can be used when making dog food?
→
The raw materials for making dog food are rich and widely available. They can mainly be divided into the following categories. You can choose several raw materials according to your formula needs.
Animal Protein: chicken meal, beef meal, fish meal, fresh meat, frozen meat, etc.
Carbohydrate Raw Materials: rice, wheat, corn, tapioca flour, etc.
Oil Raw Materials: fish oil, chicken oil, palm oil, soybean oil, etc.
Fiber Raw Materials: beet pulp, pea fiber, fruit and vegetable powder, etc.
Other auxiliary materials: minerals, multivitamins, probiotics, and other nutritional premixes.
What is the working principle of a dog food extrusion machine?
→
As the name suggests, the core step of a dog food extruder machine is “extrusion.” After various raw materials are mixed evenly and fed into the dog treat extruder, the screw inside rotates to push materials forward. At the same time, it strongly shears and squeezes them. This process creates high temperature and high pressure. It fully gelatinizes the starch in raw materials.
When materials are pushed to the machine head, under continuous pressure from the rotating screw, they are extruded from the small holes of the forming die plate. At the moment of extrusion, pressure is released. The materials expand quickly. Then the cutter in the dog food extruders cuts these expanded materials into pellets of uniform length. Dog food preforms are formed in this way.
What are the differences between wet twin-screw, wet single-screw, and dry single-screw dog food extruders?
→
Wet-process twin screw extruder machine: Suitable for high-quality large-scale production. Investment cost is high. It comes standard with a conditioning system. Inside are two intermeshing screws. They have self-cleaning and strong shearing ability. When making dog food, gelatinization is high. It can stably produce high-end dog food such as high-meat, grain-free, and low-starch formulas. The pellets are uniform and have excellent appearance.
Wet-process single-screw dog food extruder machine: Suitable for conventional low-to-mid-end dog food production. It is also equipped with a conditioner and steam boiler. Inside, only one screw conveys materials. Conveying capacity is strong, but shearing and mixing ability is limited. Overall cost performance is high.
Dry-process single-screw dog food extrusion machine: Suitable for traditional formulas and economical grain-based dog food. It has no conditioner or steam boiler. It relies on friction heat from the single screw to gelatinize materials. Gelatinization uniformity is limited. Overall investment cost is low. The machine structure is simple. Maintenance is convenient.
Summary: In terms of dog food quality, wet twin-screw > wet single-screw > dry single-screw. In terms of economy, dry single-screw > wet single-screw > wet twin-screw. When choosing, consider your dog food quality needs and investment cost.
After a dog food extrusion machine has been in production for a long time, its capacity drops. Which parts may be worn?
→
Parts that may wear include the screw sleeve, barrel liner, and die holes. When these parts wear, the screw’s shearing pressure decreases. Slippage of dog food raw materials increases. This directly lowers the capacity and gelatinization degree of the dog food extruder machine. In the end, it affects finished dog food quality.
What should I do if the dog food extruders have a fault during use?
→
After you buy our product, you enjoy a 12-month warranty. If a machine fault is not caused by human factors, you can contact us for troubleshooting and free on-site repair. If a wear part has a fault, you can also contact us to order original parts.
