SLG75A Twin-screw Extruder: Food Extrusion, Puffing, and Continuous Forming Equipment

The SLG75A twin-screw extruder is used for the extrusion, cooking, puffing, and continuous forming of cereals and puffed foods.The equipment consists of a feeding device, an extrusion puffing machine, a rotary cutting device, an electrical control cabinet, and a lubrication system. Through co-rotating intermeshing twin screws, zoned heating, and variable frequency speed regulation, it achieves stable material conveying, shearing, and die extrusion.

Main Technical Parameters

Main drive power: 75 kW; heating power: 19.2 kW; rotary cutting drive power: 1.5 kW; oil pump drive power: 0.75 kW; processing capacity: 200–250 kg/h.Adopts variable frequency speed regulation, with the overall dimensions of the extrusion main unit being 4500×1100×2200mm.

Process Control

During production, the combination of feed volume, main machine speed, temperature zones, and rotary cutting speed adapts to different raw materials and product shapes.The slicing length can be continuously adjusted within the range of 1-30mm, and the number of blades can be configured from 1 to 6.Before startup, complete barrel preheating, die installation, and hydraulic system inspection. Start the oil pump first and confirm normal lubrication before starting the main unit.

Maintenance and Safety

Regularly inspect the distribution box, reduction gear box, thrust system, rotary cutting blades, and electrical wiring, and replace the lubricating oil according to the prescribed schedule.After shutdown, clean residual material from the barrel and die head. For extended shutdowns, take anti-rust measures for components such as the screw and die head.
