RESIDUAL METAL DETECTING APPARATUS IN FOOD USING XYZ AXIS ORIENTATION DETECTION SCHEME AND A DECTECING METHOD

摘要

PURPOSE: In food residual metal apparatus for detecting an extraneous matter and the detecting method using the XYZ shaft direction sensing mode. The error generation is low made. Metal can be detected authentically. CONSTITUTION: An XYZ shaft transmission coil suspicion frequency oscillator(17-19) launches the frequency corresponding to the food of the checking object the oscillation controller. The power amplifier(20-22) offers oscillated frequency signals to XYZ shaft transmission antenna coils. The XYZ 3 shaft receive coil(28-30) receives a message the signal researched in the food of the checking object from the transmission coils of the XYZ 3 shaft.
