This invention discloses a device for detecting down composition and residual
fat content, comprising a controller, a composition detection mechanism, and a sample dispersion mechanism, a
microwave extraction mechanism, and a
drying and weighing mechanism connected in sequence. The sample dispersion mechanism includes a
sample chamber and a dispersion cavity. A miniature electromagnetic vibrator is installed at the bottom of the
sample chamber, with its top surface inclined to the dispersion cavity. The dispersion cavity is a transparent cavity with an air outlet, an air inlet, and a telescopic rod A. A mesh
sieve plate is fixed to the top of the telescopic rod A, and a sample
recovery port is located above the
sieve plate. The composition detection mechanism is connected to the dispersion cavity. The controller connects to each component. This invention achieves integrated automatic detection of down composition and residual
fat content by integrating composition detection,
microwave extraction, and
drying and weighing. It replaces Soxhlet extraction with
microwave extraction, significantly shortening the residual fat detection time and reducing the amount of
organic solvent used. Through automatic dispersion, sieving, and optical analysis, it reduces manual intervention and improves the efficiency, objectivity, and
repeatability of
composition analysis results.
