The Netherlands: Screw conveyor specialist Van Beek has developed the Sample Screw in order to allow a representative sample to be taken without halting the production process.
According to Van Beek, the machine is ideal for taking representative product samples from containers, hoppers or in-line (for example, after an outlet or in a discharge pipe). Using a small screw conveyor, a sample of the material is taken safely from the product stream without disrupting the process. Even materials with poor running qualities can be controlled in this way because a screw is used.
The sampler is easy to dismantle for quick and complete cleaning. Samples can be taken of powders, flocks, granules, flakes, pellets and slurries. It can also be used in the dairy, food, pharmaceutical and chemical industry. The sample size and frequency can be adjusted.
The sampler is driven by an air motor or electric motor with gear unit. Whether this involves bunkers, silos, hoppers or bulk transfer, in most cases few or no adjustments need to be made to the existing system.
