1. Select Machine According to Material Type
Powder Materials (Flour, Spice Powder, Starch)
Fine powder is easy to fly and absorb moisture. It requires a machine with screw metering + negative pressure dust-proof system. Avoid ordinary weighing machines that cause serious dust overflow and large weighing errors.
Granule Materials (Grain, Nuts, Feed)
Hard and fragile granules need high-precision weighing metering + buffer feeding structure. It prevents material crushing and ensures uniform bag weight.
Mixed Production (Powder + Granule)
Choose dual-mode compatible machines with one-touch switching. It supports free conversion between powder and granule production without replacing parts.
2. Confirm Packaging Range & Accuracy
Small dose packaging (10g–100g): Suitable for seasoning powder, nut sachets and sample packaging, requires high-precision screw metering.
Medium dose packaging (100g–1000g): The most common specification for daily factory production, balancing speed and accuracy.
Large dose packaging (1kg–5kg): Adopts enhanced weighing system to ensure stable filling without material overflow.
Qualified dual-purpose machines control the error within ±0.5g~±1g, meeting international product standard requirements.
3. Match Factory Production Capacity
Small batch & customized production: Standard automatic model, cost-effective, easy to operate and maintain.
Mass continuous production: High-speed upgraded model with optimized traction and sealing structure, supporting 24-hour stable operation.
4. Overseas Standard Configuration Requirements
Food-grade production: All material contact parts must be 304 stainless steel, with dust-proof and easy-clean design, compliant with CE and FDA standards.
Chemical & feed production: Equipped with anti-corrosion and anti-blocking structure to adapt to rough production environments.
5. Core Functional Configuration Tips
Dual metering system: The core configuration for dual-material production, solving both powder precision and granule stability problems.
Negative pressure dust removal: Effectively reduces powder flying and keeps the workshop clean.
Multilingual PLC control: One-key parameter storage and mode switching, friendly for foreign workers.
Common Buying Mistakes to Avoid
- Purchasing single-function machines for mixed production, resulting in high equipment costs.
- Ignoring dust-proof configuration, causing workshop pollution and unqualified products.
- Choosing low-precision machines, leading to customer complaints about uneven weight.
Conclusion
The best powder and granule packaging machine must match your material characteristics, packaging specifications, output requirements and industry standards. Dual-material compatible equipment is the most cost-effective solution for multi-product factories.
