The Challenge
Juice and soft drink manufacturers face constant pressure to deliver visually appealing, clear products while maintaining flavor integrity. Raw fruit juices naturally contain pulp, sediment, and suspended particles that can create cloudy appearances and affect consumer perception of quality.
The Solution: Strategic Filtration Approach
Filter bags provide a cost-effective, multi-stage solution for juice clarification. The process typically begins with coarse straining using nylon mesh filter bags to remove large particles like pulp and fruit pieces, followed by felt filter bags for fine particle removal.
Recommended Filter Selection:
- First Stage: Nylon monofilament mesh (100-400 micron) for pulp removal
- Second Stage: Polypropylene or polyester felt (5-25 micron) for clarification
- Bag Size: Size 1 or 2 depending on production volume
Key Benefits
- Food-safe materials meeting EC Regulation 1935/2004
- Individual packaging prevents contamination
- High flow rates with minimal pressure drop
- Extends life of downstream fine filtration equipment
Practical Considerations
For high-pulp fruits, start with larger micron ratings and consider multi-bag systems to prevent rapid clogging. Viscous juices may require oversized bags or reduced flow rates to maintain efficiency.
