The same extrusion platform can be configured for different product formats by changing the die, screw configuration and cutting system.

Typical finished products include:

• Corn puffs
• Expanded snack pellets
• Tubular snacks
• Ring-shaped snacks
• Shell-shaped snacks
• Ball-shaped snacks
• Breakfast cereals
• Expanded cereal products
• Pet food kibble
• Floating fish feed
• Sinking aquatic feed

Product shape, size, density and expansion depend on the raw material formulation, moisture content, extrusion temperature, screw speed, pressure, die design and cutting configuration.

How Does the High Capacity Food Extruder Work?

The food extruder uses two screws rotating in the same direction inside a heated barrel. Raw material enters the extrusion system through the feeding section and is continuously conveyed forward by the screws.

During the extrusion process, the material is mixed and processed under controlled temperature and pressure. The barrel heating system provides the required thermal conditions, while the screw configuration controls material conveying, mixing and shearing.

As the processed material reaches the die, pressure forces it through the die opening. When the material exits the die, the sudden pressure change causes expansion and forms the required product shape. An adjustable cutter then cuts the extruded product to the required length.

The basic process is:

Feeding → Conveying → Mixing → Heating → Cooking → Pressurization → Die Extrusion → Cutting → Further Processing

Depending on the product, the extruder can be connected to downstream drying, frying, seasoning, cooling or packing equipment.

Twin Screw Extrusion System

The twin-screw system is designed for continuous conveying, mixing and extrusion of different food formulations.

Screw Diameter

Screw Diameter: 100 mm

Screw diameter affects the working volume and processing capacity of the extrusion system. A larger screw diameter generally provides a greater processing volume, while the final capacity also depends on raw material characteristics, formulation and operating conditions.

Screw L/D Ratio

L/D Ratio: 19:1

The screw length-to-diameter ratio affects material residence time, mixing, cooking and extrusion performance. The appropriate L/D configuration is selected according to the processing requirements of the target product.

Screw Configuration

Different screw elements can be arranged according to the characteristics of the raw material and the required extrusion process.

The screw configuration can be designed for:

• Material conveying
• Mixing
• Kneading
• Shearing
• Cooking
• Pressure building
• Controlled extrusion

The final screw arrangement should be determined according to the formulation and product requirements rather than using one configuration for every product.

Temperature and Process Control

The extrusion process requires stable control of temperature, feeding rate, screw speed and other operating conditions.

The barrel is divided into controlled heating sections so that different processing stages can operate at the required temperatures.

Temperature Range: 50–180°C

The control system can be configured to monitor and adjust key operating parameters, including:

• Feeding speed
• Screw speed
• Barrel temperature
• Extrusion conditions
• Cutting speed
• Production status

Different recipes may require different temperature, moisture and screw-speed settings. Meiteng can provide recommended operating parameters based on the raw material and finished product.

Adjustable Cutting System

The cutting system is installed at the extrusion outlet and is used to control the length and shape of the extruded product.

The cutter position and cutting speed can be adjusted according to the required product format.

Different cutter and die configurations can be selected for:

• Short snacks
• Long tubular products
• Ring-shaped products
• Ball-shaped products
• Cereal products
• Feed pellets

The final cutting configuration depends on the die opening, product expansion and required finished-product dimensions.

Control System

The High Capacity Food Extruder is equipped with an automated control system for centralized monitoring and operation.

PLC Control

The PLC-based system manages the main operating parameters and allows operators to monitor the extrusion process through a touchscreen interface.

The control system can be configured to manage:

• Feeding

Machine Material and Barrel Design

The machine is designed for continuous industrial production and uses wear-resistant components in key extrusion areas.

The barrel sections use replaceable alloy sleeves to reduce maintenance difficulty when the internal working surface becomes worn.

Replaceable Alloy Sleeves

The alloy sleeves are designed as replaceable wear components. Instead of replacing the complete barrel assembly, worn sleeve sections can be serviced or replaced according to the machine configuration.

This design helps simplify maintenance and reduce potential downtime.

Food Contact Materials

Food Contact Material: Confirmed material

The exact material specification should be selected according to the product type, food-contact requirements and applicable production standards.
