DLG200 Single-Screw Main Unit: High-Capacity Food Extrusion Molding Equipment

The DLG200 single-screw extruder is suitable for extruded food production lines such as triangle chips and Doritos, and can also be configured with formulas and molds to adapt to other products.The equipment adopts a single-screw extrusion, six-zone barrel heating, and gearbox drive structure. Through stable control of screw speed, temperature, and die process parameters, it achieves continuous cooking, extrusion, and shaping.

Main Technical Parameters

Production capacity of 0-130kg/h, screw diameter φ200mm, length-to-diameter ratio 18:1, drive motor power 90kW, barrel heating power 36kW, with 6 heating zones.Rated screw speed of 74 rpm, minimum speed of 20 rpm, overall dimensions of 5500×1500×1800 mm.

Operation and Process Control

During production, feeding, temperature zones, screw speed, and forming die parameters should be set according to the raw material formula, moisture content, product thickness, and target microstructure.Before startup, inspect the barrel, screw, transmission, and electrical systems. After completing preheating and an empty-load trial run, gradually introduce the material.

Maintenance Key Points

After equipment shutdown, clean residual material from the barrel, die head, and feeding system, and ensure the heating, drive, and electrical control systems are functioning properly.Power must be disconnected and the equipment allowed to cool before maintenance or replacement of the screw, die, and transmission components.
