    Abstract: The invention relates to a sampling apparatus for use in explosive environ- ments comprising particles of a mean size of up to 500µm, the sampling ap- paratus comprising a displaceable arm having a sample container, which dis- placeable arm has a first position where the sample container is inserted into a first zone for collecting asample 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 displace- able 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.

    Abstract translation: 本发明涉及一种用于爆炸性环境的采样装置，其包括平均尺寸高达500μm的颗粒，采样装置包括具有样品容器的可移位臂，该可拆卸臂具有第一位置，其中， 样品容器被插入到第一区域中，用于将样品的颗粒收集到样品容器中，以及第二区域，其中可移动臂在产品流之外，第二区域被容纳在具有用于可移位臂的开口的壳体中。 采样设备具有在第一和第二区域之间的接口，该接口从包括可关闭构件，闸阀或气刀的列表中选择。 本发明还涉及一种包括本发明的干燥室和取样装置的干燥机。 在另一方面，本发明涉及估计有机颗粒样品的流动性的方法。

    Abstract: The invention concerns a powder drying system (1 ) comprising a carbon monoxide (CO) gas detection system adapted for detection of CO gas from smoldering powders in a powder drying system component, such as a spray dryer chamber (200), a fluid bed (500) or a bag filter (400), which CO gas detection system comprises at least one inlet CO gas detector (3) arranged on at least one gas inlet of a powder drying system component such as to provide at least one inlet CO gas content measurement, at least one outlet CO gas detector (3) arranged on at least one gas outlet of a powder drying system component such as to provide at least one outlet CO gas content measurement, and an analyzing unit (5) adapted for receiving the at least one inlet CO gas content measurement, receiving the at least one outlet CO gas content measurement and comparing the sum of the at least one inlet CO gas content measurement and the sum of the at least one outlet CO gas content measurement while compensating for dilution, mixing, and time delay of the outlet CO gas content measurement. At least the at least one outlet CO gas detector (3) comprises an IR laser transmitter and is adapted for detecting over a measurement volume (6) and is arranged on the at least one gas outlet in such a way that said measurement volume (6) extends directly inside a gas flow (20) in said at least one gas outlet.
