Uni-Dust (Powder recycler/collector)

Take control of excess dust from powder filling machines, tablet presses or similar equipment. The ground-breaking technology behind Hanningfield Uni-Dust guarantees a high recovery/collection of the powder in-line.


More information

Made of 316L stainless steel, the Uni-Dust cyclone is a hygienic way to capture excess dust in a controlled environment of the process room. The equipment is intended to be retrofitted to equipment that generates dust.

Process validation is not affected, making it ideal for both new and existing processes. I linje med cGMP gör Uni-Dust förluståtervinning/uppsamling till en enkel sak.

Traditionally, waste from powder filling equipment such as tablet presses and capsule filling machines is diverted to a central facility.

Dust/filter system is in the facility. This process can result in a mixture of different powders that are stored in the filter system and can cause environmental damage and operator health upon exposure.

The cyclone separates the solid material from the clean air. Typically, 95–99% of the excess powder is “captured” in a collection container. The air then passes through an optional “Control/filter system” eg HEPA filter. This increases the system’s efficiency to 99.99%.

The purified air continues to the usual dust collection point.

Uni-Dust collects these wastes and keeps them in a controlled area separated from the process room. Another advantage of collecting these surplus materials from the processing room is to minimize batch losses.

Batch losses can be verified and recorded by removing the collection container. The powder from the collection container can be weighed, recorded and possibly returned to the process.

Uni-Dust has a filterless construction and provides an extremely high degree of separation, in some cases to almost 100%. However, to maintain total integrity, a HEPA filter can be installed on the outlet of the Uni-Dust.

A number of configurations are possible, so that the cyclone can be integrated into various system applications.
