SubscribeLarox Corporation is a world-leading supplier of value added solid/liquid separation process solutions. The 2004 acquisition of the Outokumpu Technology filter business further consolidates Larox's position as one of the leading filtration solution suppliers for the food, pharmaceutical and biotechnology industries.
The new Larox brings together under one company the capabilities and resources of Larox’s automatic pressure filters, Scheibler polishing filters, the Pannevis range of horizontal vacuum belt filters and the Hoesch range of pressure filters. The new products and technologies enable Larox to 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, including B2, B12, C and E. 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, drug intermediates, and bulk chemicals.
The newest addition is the Larox PF C 3.2 based on our time-tested technology but designed to tackle application-specific needs and meet all the process-performance and operational requirements of our clients and their customers in the pharmaceutical and biotechnology industries.
This newest C Series filter features the same reliability/performance of existing C Series products plus has the following improvements:
- The processing area of the filter is totally separated from the mechanical section.
- Sloping surfaces have been introduced to allow for better cleaning
- All surfaces and welds in contact with the product have high specification finishes
- All material in contact with the product, or in the processing area generally, is selected in order not to affect the product in any way
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.
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 in that it is totally enclosed design. It offers the same capabilities as the new Larox C series filter but some of the special features of the DS filter include:
- Built in clean-in-place (CIP) a standard feature
- Double-sided filtration allows multiple cake washing and cake drying options
- Corrosion resistant designs available.
- Gas-tight construction available to handle solvent wetted processes.
Applications for the DS include fermentation broths, enzymes and plant extracts
Larox DS automatic pressure filters provide total process containment and the ability to process solvent wetted products.
HORIZONTAL VACUUM BELT FILTERS
Pannevis horizontal belt filters are used for the continuous separation of slurries into filter cake and filtrate, have been supplied to the pharmaceutical industry for over 30 years. The unique RT design has been developed in both open and enclosed configurations for sanitary operation to meet the most severe FDA final pharmaceutical requirements and cGMP.
For pharmaceutical processes where batch identity is required, the filters can be operated on an intermittent basis with 100% cleaning between batches. The RT filters have continuous cloth cleaning with 100% solids recovery unlike many other batch systems. Full clean-in-place capability ensures 100% elimination of cross batch contamination.
Applications include antibiotics, steroids, Intermediate and final pharmaceuticals, vitamins. The RT-GT gas tight design is totally enclosed making it suitable for solvent wetted processes, potent products and toxic or hazardous processes. A Fume Tight RT-FT option can be used for non-solvent processes.
Pannevis filters offer full multi-step processing with a single unit including multiple variations of the following steps separation, cake washing (co-current or counter-current), cake compression and cake drying (thermal). With thermal drying cakes can be discharged dry to les than 0.1% final moisture.
Pannevis RT filters are available in open, enclosed or gas-tight configurations to meet FDA final pharmaceutical specifications.
POLISHING FILTERS
Scheibler polishing filters use adsorption filtration to remove and recover solids in low concentrations from process liquids. The quality of the resulting filtrate increases production capacity while boosting the quality of plant end products
Adsorption filtration reduces solids concentrations in filtrates to levels of 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.
Scheibler polishing filters remove and recover solids in low concentrations from process liquids.
