Automatic Sweet Potato Noodle Machine

Updated: 2026-07-20

Overview

The automatic sweet potato noodle machine is engineered for large-scale production of traditional sweet potato starch noodles, a staple in Asian cuisine. It streamlines the labor-intensive manual process by automating mixing, extrusion, and cutting into uniform strands. Designed for food manufacturers, it ensures hygienic production with food-grade materials and consistent output quality. Modern versions incorporate PLC controls for precision adjustments to noodle thickness (1–5 mm) and length (10–30 cm), catering to diverse market preferences. Its robust stainless steel frame guarantees durability, while modular designs simplify maintenance and part replacement.

Structure and Working Principle

The machine comprises a hopper for starch slurry input, a twin-screw extruder for kneading and gelatinization, a molding die for shaping, and a rotary cutter for portioning. The slurry is heated indirectly during extrusion, ensuring even cooking ('self-cooking' mechanism) without external steam. Advanced models feature sensors to monitor temperature and pressure, preventing overcooking or blockages. The synchronized conveyor belt cools noodles post-cutting, reducing breakage. This closed-system design minimizes human contact, aligning with food safety standards like ISO 22000.

Key Features

1. **Efficiency**: Processes 50–200 kg/hour, reducing production time by 70% compared to manual methods. 2. **Customization**: Interchangeable dies allow round, flat, or hollow noodle varieties. 3. **Energy Saving**: Low-power motors (3–7.5 kW) and heat recovery systems cut operational costs. 4. **Hygiene**: Stainless steel surfaces resist corrosion and enable easy sanitation. Optional add-ons include dust collectors for starch powder and automated packaging integration.

Application Areas

Primarily adopted by: - **Noodle manufacturers**: For bulk production of sweet potato vermicelli, glass noodles, or hot pot staples. - **Agricultural cooperatives**: To add value to sweet potato harvests via processed goods. - **Export-oriented factories**: Meeting international demand for gluten-free Asian noodles. Small-scale models suit startups, while industrial units serve OEM contracts with supermarkets or restaurant chains.

Maintenance and Precautions

**Daily**: Flush the extruder with warm water post-use; inspect screw wear monthly. **Monthly**: Lubricate bearings and calibrate temperature sensors. Avoid using low-starch blends (below 60% purity) to prevent jamming. Always disconnect power before disassembly. For prolonged downtime, apply food-grade oil to prevent rust.

B2B Procurement Guide

1. **Capacity Needs**: Assess hourly output requirements (e.g., 100 kg/hr for mid-sized factories). 2. **Certifications**: Verify CE, FDA, or local food machinery compliance. 3. **Supplier Evaluation**: Prefer manufacturers with 5+ years of noodle-machine specialization and spare-part availability. 4. **Cost Analysis**: Balance upfront price against energy consumption and maintenance costs (approx. $200/year). Sample contracts should cover installation training and a 1-year warranty.
