A New Detecting Instrument to Measuring Water Content for Industry Processing Residues

Analyzed comprehensive effects of glass surface and glass, when combined with residue that have different water content, on incident ray, designed a instrument that can detect brightness of reflex. Take normal distilled spirit residue, beer residue, vinegar residue as sample. Use electrical fan dryer to make dry residue sample which contains almost 0% of water, use electrical scale, measuring cylinder, burette, blender, atomizer to make residue samples which contain 10%, 20%, 30%, 40%, 50%, and 60% of water. Put residue samples have different water content under a piece of glass, put double-D fiber sensor perpendicularly to the glass, one fiber is used to output ray signal, the other one is used to receive ray signal: read, record, and process light signal from residue samples with different water content. Seen from three data of residue experiments: Three types of residue's comprehensive effect on incident ray is nonlinear. Three types of residue have the strongest effect with 20% of water content. Experimental results are used to develop detecting instrument.
