ABSTRACT:
A blending apparatus comprises a blender including a container having a wall, the wall including a window. The container rotates about an axis of rotation. A wireless spectrometer is mounted to the container and operates through the window, in a direction that does not intersect the axis of rotation, for obtaining a set of spectroscopic data regarding the product during an operation of the blender. In addition, a method for assaying a blended product in a blender includes mounting a wireless spectrometer to the container, rotating the container about its axis of rotation so as to blend the product; operating the wireless spectrometer through a window in the container, in a direction that does not intersect the axis of rotation, to obtain spectroscopic data regarding the product during the blending, and determining a homogeneity of the product from the spectroscopic data.
