Small Units for Brine Purification
The Microflow XL-M Brine systems are specifically designed to meet needs and requirements of brine purification in small and medium cheese plants. Clarification is achieved without the need for filter aids or centrifuge. The small Microflow XL-M unit provides an environmentally friendly solution for longer brine life, with a reliable microbial stabilization which reduces the risk of cheese contamination from spoilage or pathogenic microorganisms during the brine salting process.
The cheese brine purification system utilizes Pall's proven high area, hollow fiber membranes with unique mechanical strength and excellent chemical resistance, which allow high productivity and repeated exposure to aggressive cleaning regimes.
The Microflow XL-M unit, designed for manual operation with minimum assistance during process cycles, provides cost-effective and efficient brine purification. When coupled with the user friendly interface and a compact footprint, the Microflow XL-M Brine system is the easy solution for reliable brine purification.
Cost Savings Benefits
With Pall's extensive experience in crossflow filtration of food and dairy streams and dedication to simplified process design and control logic, the Microflow XL-M Brine system incorporates unique features which enable dairies to perform clarification at low operating costs while providing constant and high brine filtrate quality.
These include:- PVDF membranes with high mechanical strength for longer service life
- High area, high flow modules for more compact and more economical systems
- Backpulse capability for increased system productivity
- Hollow fiber membrane with 1.4 mm open channel for optimized cleaning
- On board cleaning tank, process connections and operating elements on one side of the system for easy integration and operation
- Process cycles running automatically with low attendance from operator, initiating regeneration and cleaning cycles, for reduced labor and downtime
- Pressure and temperature monitoring, production flux rate set by operator and critical parameter values diagnosed by the PLC for enhanced reliability
- Transparent module housing to confirm filtrate quality and enhance troubleshooting capabilities
- User friendly interface for efficient operation
