Seasoning Industry

Seasoning products (such as powdered seasonings, granular seasonings, etc.) may encounter various issues during the packaging process due to factors such as material properties, equipment operation, and environmental conditions. These issues not only affect production efficiency but may also result in product quality failing to meet standards. The following are common issue categories and their specific manifestations:

1. Packaging issues caused by material properties
The physical properties of seasonings (such as particle size, moisture content, and flowability) are the primary sources of issues during packaging, particularly for powdered and small granular seasonings:
Powdered seasonings (e.g., pepper powder, chilli powder) with high moisture content tend to clump together in hoppers and pipeline walls, causing poor material flow; granular seasonings (e.g., Sichuan pepper grains) with inconsistent sizes may form ‘bridging’ (where materials support each other and fail to fall) at the feed opening, causing the packaging machine to stop feeding and disrupting continuous operation.
Impact: Increased frequency of machine shutdowns for maintenance, resulting in a 10%-20% decrease in production line efficiency.

2. Dust dispersion
Powdered seasonings can generate dust during conveying and discharge, not only polluting the production environment but also potentially being inhaled by operators, while also causing material loss (loss rate of approximately 1%-3%).
If traditional mechanical feeding methods (such as screw conveyors) are used, dust issues are more severe. While pneumatic vacuum feeders can reduce dust, leakage may still occur if sealing is inadequate.

3. Uneven material mixing (for composite seasonings)
For example, in hot pot base seasoning packets containing powder, granules, and oils, if mixing is uneven before packaging, a single packet may have an excessive or insufficient amount of a particular component, affecting taste consistency.
