Larox Corporation - Value-Added Solid / Liquid Separation Solutions for Food, Pharmaceutical and Biotechnology

Larox Corporation is a world-leading supplier of value added solid / liquid separation process solutions. Larox brings together the capabilities and resources of Larox automatic pressure filters, Scheibler polishing filters, Pannevis horizontal vacuum belt filters. We offer a full range of filter options for many food, pharmaceutical and biotechnology applications.

Larox is dedicated to serving these industries by developing high-performance, reliable separation solutions which expand production capacities, simplify processes, reduce energy and manpower requirements and improve product quality and recovery.

The new grouping brings together over 100 years combined experience in supplying cost effective and reliable solid / liquid separation solutions. Proven applications include antibiotics, enzymes, fermentation broths, intermediate and final product pharmaceuticals and vitamins. Currently there are over 100 installations worldwide.

Understanding the customer's needs is an important part of product development for Larox. Partnering with customers from initial development through to full-scale manufacturing while helping to reduce costs and uncertainty while increasing yields and confidence has led to the development of the Larox C 3.2 series pressure filter, the Pannevis RT-GT gas tight filter and the Larox DS pressure filter.

AUTOMATIC PRESSURE FILTERS

Larox C Series automatic pressure filters are designed to exceed stringent requirements for end-product quality and consistency, as well as production efficiency, reliability and safety. Larox C Series filters outperform conventional production methods for starches, enzymes, fermentation broths - and drug intermediates. The newest addition is the Larox PF C 3.2 based on our time-tested technology but designed for application-specific needs to meet the process-performance and operational requirements of our clients and their customers.

The Larox DS automatic pressure filters has been specifically designed for foods, pharmaceuticals and solvent-wetted products. The filter differs from the Larox C series as it is totally enclosed design. Some of the special features of the DS filter include:

• Double-sided filtration allows multiple cake washing and cake drying options
• Corrosion resistant designs available
• Gas-tight construction available to handle solvent wetted processes

HORIZONTAL VACUUM BELT FILTERS

Pannevis belt filters are used to continuously separation slurries into cake and filtrate, and have been supplied to the pharmaceutical industry for over 30 years. The unique RT design is available in both open and enclosed configurations for sanitary operation to meet FDA final pharmaceutical requirements and cGMP. Where batch identity is required, the filters are operated on an intermittent basis with 100% cleaning between batches. The RT filters have continuous cloth cleaning with 100% solids recovery. Full CIP capability ensures 100% elimination of cross contamination.

The RT-GT gas tight design is totally enclosed making it suitable for solvent wetted processes, potent products and toxic or hazardous processes.

Pannevis filters offer full multi-step processing with a single unit including multiple variations of cake washing, cake compression and cake drying. With thermal drying cakes can be discharged to less than 0.1% final moisture.

POLISHING FILTERS

Scheibler polishing filters use adsorption filtration to remove and recover solids in low concentrations from process liquids. Adsorption filtration reduces solids concentrations in filtrates to parts per million with very low operating costs. Costly filter aids are unnecessary in the majority of applications. Maintenance costs are minimal as there are no moving parts and cloth cleaning and solids discharge are carried out automatically. The filter is normally only opened to replace the filter cloths.
