Question

How to choose a filling machine for powder products?

What factors should be considered when choosing powder packaging?

How long can packaged powder be safely stored?

What challenges might arise when packaging powder products?

Accepted Answer

Powder Characteristics

Flowability: Powders with good flow can use gravity or volumetric filling machines. For powders with poor flowability, forced feeding or vibration feeding equipment is recommended.
Particle Size: Fine powders tend to create dust, so equipment with good sealing is necessary. For larger particles, machines that are less prone to blockages should be selected.
Moisture Content: Moist powders tend to clump, so machines with good moisture protection are essential.

Filling Precision

High Precision Needs: For products like pharmaceuticals or high-value foods, a servo-driven or high-precision sensor-controlled filling machine should be chosen.
General Precision Needs: For typical food or chemical products, a standard volumetric or auger filling machine is suitable.

Filling Speed

High-Speed Production: For high-volume production, choose multi-head filling machines or highly automated equipment.
Low-Speed Production: For lower production rates, single-head or semi-automatic filling machines are a good option.

Accepted Answer

Moisture Protection: Powder products require specialized packaging solutions to prevent moisture and contamination.
Spill Protection: Proper packaging is critical to prevent spillage during transport and storage.

Accepted Answer

The main factors affecting the shelf life of packaged powder include temperature, humidity, and light exposure. Typically, packaged powder can be safely stored for one to two years, but the shelf life may vary depending on the specific powder.

Accepted Answer

Packaging powders poses a higher risk of dust generation, which can be inhaled and cause respiratory issues. Additionally, dust formation can lead to product wastage as particles blow into the air.

To solve this, machines with dust collection systems should be chosen. These systems use positive pressure to collect dust and channel it into a collector. Furthermore, the powder packaging area must be well-ventilated to ensure a clean and safe working environment.
