SLG70-CII Twin-screw Extruder: Modular Food Extrusion and Puffing Equipment

The SLG70-CII twin-screw extruder is used for producing puffed snacks, cereal porridges, fillers, and other extruded food products.The equipment consists of a frame, a twin-screw feeding system, a main motor, a distribution box, a barrel, and a rotary cutting system. It adopts a modular screw configuration and a co-rotating meshing structure, allowing the screw configuration, temperature zones, and operating parameters to be adjusted according to the material and product process requirements.

Main Technical Parameters

Main motor power: 37 kW; feeding drive power: 0.55 kW; barrel heating power: 10 kW; rotary cutting drive power: 0.75 kW; oil pump power: 0.37 kW.Screw diameter φ70mm, L/D ratio 22.2:1, overall dimensions of the extrusion main unit 3720×1196×1717mm.

Structure and Forming Control

The twin screws are composed of a core shaft, screw sleeve, shear ring, and kneading blocks, allowing for various combinations tailored to different materials.The twin-screw feeding system employs variable frequency drive control to regulate the feed rate.The slicing length can be continuously adjusted within the range of 1-30mm, and the number of blades can be configured from 1 to 4.During production, coordinate the feeding, temperature, main machine, and rotary cutting speed in accordance with the product shape and curing requirements.

Safety and Maintenance

Before startup, inspect the feeding system, barrel, screw, transmission, and oil circuit to ensure there are no foreign objects or abnormalities.Cut off the power supply before maintenance. Inspect the gearbox, bearings, screw assembly, rotary cutting blades, and electrical system at regular intervals, and ensure reliable lubrication and grounding protection.
