The multi‑functional twin‑screw puffed snack production line supports continuous automatic production with an output of 200‑600 kg per hour. By replacing molds and adjusting process parameters, it can process dozens of product types, including textured soy protein, artificial rice, tartary buckwheat chips, bread crumbs, various puffed snack foods, and multigrain flakes.
The entire puffed production line requires only 2‑3 operators for daily operation. It offers fully automatic operation, covering the entire process from raw material mixing to finished‑product cooling and seasoning.
Widely adopted by snack food factories, grain deep‑processing plants, and plant‑protein processing enterprises, it helps manufacturers cut equipment investment costs, enable flexible multi‑product switching, and improve overall production efficiency.
Core advantages of extruded puffed snack production line
- Multi‑function for diversified products: Produce various puffed snacks by changing moulds & adjusting parameters, saving repeated equipment investment.
- Stable output by twin‑screw extrusion: Self‑cleaning co‑rotating twin‑screw with VFD and forced‑lubrication protection. Well‑mixed materials guarantee consistent taste & expansion and a lower defect rate.
- Full automation for labor saving: Automatic workflow from mixing, extrusion, drying, seasoning to cooling. Labor only for feeding & discharging, less human‑material contact to meet food hygiene standards.
- Energy‑saving electric tunnel drying: Adjustable temperature & variable‑frequency mesh belt. High thermal efficiency with insulation layer. Openable bottom cover for easy residue cleaning.
- Food‑grade material & custom solution: Stainless steel for material‑contact parts, carbon‑steel frame. Optional double‑drum / octagonal‑barrel seasoning. Custom layout & configuration for workshops.
- Reliable after‑sales support: 1‑year warranty after commissioning. Manuals, wearing parts and process guidance are supplied for easy maintenance.

Complete production process & equipment configuration
This twin-screw puffed snack production line supports fully automatic continuous operation, with smooth process connection and optional packaging equipment for mass production.
Production flow
Raw material preparation → Powder mixing → Screw feeding → Twin-screw extrusion & puffing → Air conveying/vibrating screening → Multi-layer drying → Elevator conveying → Oil spraying → Drum / octagonal barrel seasoning → Air cooling conveying (connectable with automatic packaging machine).
Standard equipment list & main functions
- Powder Mixer: Food-grade stainless steel contact parts, batch mixing with adjustable mixing time (30s–3min), ensuring even blending of powder and water.
- Screw Feeder: Height-adjustable stainless steel structure with movable casters, delivering powder materials steadily to the extruder.
- TN Series Twin-Screw Extruder (Core Unit): Independent variable frequency control for feeding, main drive and cutting; sectional temperature control and forced lubrication system. Self-cleaning screw design; product varieties can be quickly changed by replacing dies, suitable for protein, grain and starch raw materials.
- Air Conveyor / Vibrating Sieve: Separating agglomerated puffed products and pre-cooling materials. Closed air conveying avoids material leakage and contamination.
- Electric Heating Tunnel Oven: Variable-speed mesh belt with independent temperature control, hot air circulation for moisture removal. Low energy consumption with thermal insulation layer; detachable bottom cover for easy residue cleaning.
- Bucket Elevator: Convey materials between working procedures to maintain continuous production.
- Oil Sprayer: Atomize oil evenly to achieve consistent oil coating.
- Seasoning System: Two options: double-drum type for simple powder coating; double-head octagonal barrel type for quantitative oil injection and slurry spraying, ideal for high-end formulated snacks.
- Băng chuyền làm mát: Equipped with multiple fans to rapidly cool down finished products and meet packaging storage requirements.
The downstream end of a puffed snack production line can be connected to a packing machine—such as a pillow-type snack packaging machine—to automate the bagging and sealing of finished products, enabling an integrated process from raw materials to packaged final products.
Get a customized solution
When purchasing a puffed snack production line, please sort out the following information in advance for fast proper‑equipment matching:
- Estimate target hourly and daily output to confirm capacity requirements.
- Clarify your main products, and confirm if frequent product switching is needed, such as textured soy protein, artificial rice and puffed snacks.
- Confirm seasoning requirements: simple powder coating or quantitative oil / syrup spraying, which decides between double‑drum and octagonal drum seasoning system.
- Check factory power supply condition, workshop area, ceiling height and space for equipment placement.
- Confirm whether connection with downstream packaging machine is required, as well as other customized demands.
If you plan to build a new puffed-food processing plant or upgrade an existing one, please advise your target output, main products, and workshop conditions. We will recommend suitable configurations and provide complete process and equipment solutions.
