Unleash the potential of your starch process

The primary dewatering mechanism is pressure filtration, in which a pressing force of up to 16 bar can be used. As a result, PF filters consume significantly less energy than centrifugal separators. Plant construction and machine maintenance are also simpler because there is no high-speed revolving mass and no continuously moving parts.

We’ve delivered over 60 pressure filters to starch producers around the world, helping them save energy, reduce costs, and improve yield. Our filters are easy to adapt to both old and new production lines and can be installed with minimal downtime.

Benefits

• Ensure high-quality and uniform washing with our fully automated process control and continuous optimization
• Run 24/7 without the need for regular cloth changes
• Ensure minimal solids loss in filtrate
• Reduce wash water consumption
• Enable more starch to be used in packing instead of being an expensive waste problem
• Significantly increase dryer capacity with lower moisture in cake
• Get 24-hour support from our global service network

Applications

Washing and dewatering of native and modified starches such as:

• Corn (Maize)
• Potato
• Rice
• Tapioca (Cassava)
• Wheat

Save energy, reduce wash water consumption, and increase plant capacity with Larox® PF pressure filters for starch dewatering and washing. Larox PF pressure filters and life cycle services for native and modified starches in industrial food and pharmaceutical applications are based on our decades of experience and proven track record.

Our filters ensure a timely return on investment. They are easy to adapt to both old and new production lines and can be installed with minimal downtime, meaning the initial investment is similar to that of centrifuges.

In addition to their higher production capacity, our filters have lower running costs compared to centrifuges due to their lower energy, water, solid waste, and wastewater treatment needs. They are also easier to maintain as there is no high-speed revolving mass and no continuously moving parts. 

Increased production

• Eliminates product loss (starch solids) to filtrate with effective pressure filtration
• High availability due to fully automatic operation
• Lower moisture in cake leads to significant increase in dryer capacity
• Process can run 24/7 without the need for regular cloth changes

Lowest possible solids load to waste water treatment

• Automatic pressure filtration with continuous cloth results in exceptionally clear filtrate

Significantly reduced water and energy consumption

• Horizontal chamber pressure filtration provides more efficient cake washing, reducing the cake washing ratio while improving ash content
• Reduced equipment power consumption
• Lower moisture in cake helps cut dryer energy consumption

Improved starch quality and consistency

• Efficient cake washing improves starch quality
• Dryer cake requires less thermal drying after filtration leading to improved product quality
• Fully automatic operation results in a more consistent product
