Reliable Sampling of Bulk Materials and Product Streams
For reliable quality control of bulk materials, AZO offers a variety of automatic and manual sampling unit designed for different installation scenarios. These systems enable the safe collection of random samples or continuous sampling from downpipes, unpressurized containers, and silo filling lines.
Controlled sampling without exposed product areas
With the PRS and PRK models, the sample is transferred directly from the product stream into a transparent sample container. After sampling, the container can be quickly removed and sealed. The closed system reduces the risk of contamination of the sample and the product area and allows the sample to be transported directly to the laboratory.
The PRS is suitable for both spot sampling and continuous sampling. Depending on the requirements, the sampling screw is available with pneumatic, electric, or manual drive. The PRK uses a sampling piston and is designed for spot sampling from downspouts or unpressurized containers containing free-flowing products.
Sampling directly during silo filling
The PRA pneumatic sampling unit allows for sampling as soon as bulk materials are delivered by silo trucks. During silo filling, a defined quantity of product is directed into the separator and then discharged into a sealable sample container. This allows the delivered product to be tested in the laboratory before it is approved for further production.
If irregularities are detected during the analysis, the affected shipment can be blocked from further production. In this way, sampling at the time of goods receipt supports the controlled release of raw materials.
Compact design for easy handling and cleaning
Compact, easy-to-clean designs and quick installation facilitate the efficient use of the sampling units in production environments. Depending on the model, integration is achieved via a Tri-Clamp connection or a flange; pneumatic and manual drives are available for the PRS and PRK models, respectively. The PRA is specifically designed for pneumatic sampling during silo filling.
