Co-extruded Snack Processing
Center-Filled Snack Production Line
A complete co-extrusion line for center-filled rice snacks, cereal pillows, filled sticks and similar products. ZEKO matches the extruder, filling unit, shaping system, dryer and seasoning section to the shell formula, filling material and required output.
Models And Reference Capacity
The extruder establishes the main output range. Drying, coating, milling, cooling and packing equipment must be sized around the same product load.
| ZEKO configuration | Reference output |
|---|---|
| ZK-65 | Approx. 100-150 kg/h |
| ZK-70 | Approx. 200 kg/h |
| ZK-75 | Approx. 300-400 kg/h |
Reference output changes with shell formula, filling viscosity, product dimensions, expansion ratio and dryer load. ZK-65 and ZK-70 are common commercial choices; larger projects are configured after product evaluation.

Production Process
A practical process flow for project discussion. Individual stages are adjusted according to formula, product quality and factory utilities.
Equipment Scope And Configuration
A useful quotation separates the required process from optional automation and packing equipment.

Typical Equipment Scope
- Flour mixer and screw conveyor
- Twin-screw extruder with co-extrusion die
- Filling preparation and injection unit
- Shaping or cutting machine
- Electric, natural-gas or steam drying oven
- Seasoning drum, cooling conveyor and optional packing
Important Project Decisions
- The outer shell formula must expand consistently while holding the filling.
- Filling viscosity and temperature affect injection stability and product sealing.
- Product length, cross-section and filling ratio determine die and cutter selection.
- Dryer capacity must match the extruder so the shell reaches the required final moisture.
Information Needed For Quotation
Send these details so ZEKO can select the process, output platform, utilities and workshop layout without relying on a generic equipment list.
- Finished-product photos and target dimensions
- Shell formula or main flour ingredients
- Filling type and preparation method
- Required hourly output
- Factory voltage, oven heat source and workshop size

Practical answers about products, capacity and line configuration.
What products can the center-filled snack line make?
Typical products include filled cereal sticks, rice snacks, pillows and other co-extruded products with sweet or savory fillings.
Can product shape and filling ratio be changed?
Yes. The die, shaping system, cutter and filling settings are selected around the required cross-section, length and filling ratio.
Which extruder models are available?
Reference platforms are ZK-65 at approximately 100-150 kg/h, ZK-70 at approximately 200 kg/h and ZK-75 at approximately 300-400 kg/h.
Which oven heat sources are available?
The drying oven can use electricity, natural gas or steam according to capacity and local utilities.
What information is needed for a quotation?
Send product photos, shell ingredients, filling type, dimensions, capacity, voltage, heat source and workshop size.
