Abstract
The invention relates to a sampling apparatus for use in explosive environments comprising particles of a mean size of up to 500 μm, the sampling apparatus comprising a displaceable arm having a sample container, which displaceable arm has a first position where the sample container is inserted into a first zone for collecting a sample of particles into the sample container, and a second zone where the displaceable arm is outside the product stream, the second zone being contained in a housing with an opening for the displaceable arm. The sampling apparatus has an interface between the first and the second zone, which interface is selected from the list consisting of a closable member, a gate valve or an air knife. The invention also relates to a dryer comprising a drying chamber and a sampling apparatus of the invention. In a further aspect the invention relates to a method of estimating the flowability of a sample of organic particles.
