SLG115-A Twin-screw Extruder: Large-Scale Food Extrusion and Puffing Equipment

The SLG115-A twin-screw extruder is a versatile, large-scale standardized food extrusion and puffing equipment, suitable for processing a variety of flavored puffed snacks, textured vegetable protein, cereal granular and flake porridges, cold dessert fillings, pastry fillings, and solid powder products.The equipment employs a twin-screw high-temperature and high-pressure extrusion technology to achieve mixing, shearing, cooking, puffing, and shaping of the material.

Main Technical Parameters

Main motor power: 132 kW; feeding drive power: 2.2 kW; barrel heating power: 88 kW; rotary cutting drive power: 3 kW; oil pump power: 0.75 kW.Screw diameter φ115mm, length-to-diameter ratio 28.09:1, overall dimensions of the extrusion main unit 6651×1290×2365mm.

Structure and Operation

The equipment is mainly composed of the frame, feeding system, main motor, distribution box, barrel, and rotary cutting system.When starting up, first install and tighten the die head, complete barrel preheating, start the oil pump to confirm normal oil pressure, and then start the main motor and feeding system.Once the material flow is stable, start the rotary cutting system and adjust it to the target length and shape.

Maintenance Key Points

Regularly inspect the fixing bolts of the connecting flanges, gearboxes, reducers, and main motor. Replace the lubricating oil in the reducer according to the scheduled intervals, and replace the lubricating oil in the gearbox after it has operated for a specified duration.During extended periods of inactivity, anti-rust treatment should be applied to components such as the die head and screw, and the electrical wiring and gear box operating noise should be inspected regularly.
