Coconut Paste Filtration Using INDRO Liquid Filtration Bags
Industry
Food Processing / Plant-Based Ingredients Application
Coconut paste filtration prior to coconut milk, coconut cream, and downstream food processing
Application Background
Coconut paste is widely used in the production of coconut milk, coconut cream, plant-based desserts, bakery fillings, and ready-to-eat food products. During processing, ground coconut meat is mixed with water to form a thick, viscous paste containing natural fibers, fine shell residues, and agglomerated solids.
To meet food quality standards and ensure smooth texture, these impurities must be effectively removed without damaging the product or causing excessive pressure loss.
Filtration Challenges
Coconut paste presents several challenges for liquid filtration systems:
High viscosity leading to unstable flow through fine filters
High fiber content causing rapid clogging
Natural fats and oils contributing to filter blinding
Strict food-grade requirements for materials and hygiene
Need for stable production during high-load operation
Traditional cartridge filters used by the processor showed limited dirt-holding capacity and required frequent replacement, resulting in downtime and increased operating costs.
INDRO Filtration Solution
To address these challenges, the processor implemented a bag filter system using INDRO liquid filtration bags, installed in stainless steel filter vessels designed for food applications. INDRO filtration bags were selected for their high dirt-holding capacity, consistent filtration performance, and suitability for viscous, fiber-rich fluids such as coconut paste.

Process Description
Coconut paste enters the bag filter vessel under controlled pressure
Fibers and solid contaminants are retained inside the INDRO filtration bag
Cleaned coconut paste flows downstream to further processing or packaging
Once differential pressure reaches the set limit, the filter bag is replaced
The bag-change process is fast and requires minimal operator intervention, helping maintain production continuity.
Performance Results
After implementing INDRO liquid filtration bags, the processor achieved the following improvements:
Improved product consistency and smoothness
Extended filtration cycles due to high dirt-holding capacity
Reduced pressure buildup during operation
Lower maintenance frequency and downtime
Reduced total filtration cost
The system maintained stable performance even during peak production when coconut paste viscosity and fiber content were highest.
Why INDRO Liquid Filtration Bags
INDRO liquid filtration bags are well suited for coconut paste and similar food applications because they:
Handle high fiber and solid content efficiently
Offer flexible micron selection for different product specifications
Provide gentle filtration that protects product quality
Support scalable production with multiple bag sizes and housings
Related Applications
Coconut milk and coconut cream
Fruit purees and concentrates
Plant-based beverages
Sauces, syrups, and viscous food liquids
Conclusion
This case study demonstrates how INDRO liquid filtration bags provide a reliable and cost-effective solution for coconut paste filtration. By combining food-grade materials, high capacity, and stable performance, INDRO helps food processors achieve consistent quality, operational efficiency, and reduced filtration costs.
For viscous, fiber-rich food applications, INDRO liquid filtration bags are a proven choice.
