FOOD INGREDIENTS
Overview
Overview
Efficient recovery of active pharmaceutical ingredients (APIs), chemical substances and food powders after drying applications such as spray and fluid bed drying is frequently a problem. The same problem occurs in many milling and micronization applications.
To recover these sensible products, cyclone collectors are frequently irreplaceable equipments for allowing a direct powder capture and avoiding product holdup of filters. Cyclones also avoid contamination of filter bags, product cross contamination and product degradation with temperature.
However, product losses due to cyclones' low efficiency represents a high cost as a consequence of the value of particles.
Where applicable, cyclones have to be complemented with specialized bag filters to increase yield or to avoid emissions to the atmosphere. These filters are usually associated with difficult cleaning and downtime.
Client's needs include a very efficient cyclone system, minimizing the escape of particles to end stage collectors such as bag filters, usually unable to deliver usable product due to contamination with filter fibres or different product cross contamination.
In various food ingredient processing applications, such as sugar coatings or flavour products, batches of different powders are produced through drying processes such as spray or fluid bed drying. ReCyclone® MH systems are indicated to upgrade Hurricane cyclones' performance and thus minimizing powder losses (down to 50 %). Lower emissions frequently are sufficient to comply with regulatory limits and to avoid the use of bag filters downstream.
When production is fulfilled in smaller batches, the cyclone systems need to be thoroughly cleaned and the product collected in the filters typically cannot be used due to the difficulty in cleaning the filter elements. CIP able filters, on the other hand, cannot always be used and are very expensive.
ReCyclone® MH systems can be designed with CIP cleaning systems and heat tracing (or other) to avoid condensation risks. Efficiency is often high enough to avoid the use of bag filters downstream.
