Abstract

PURPOSE:To make it possible to automatically measure the mixing ratio of fine grains, by introducing whole grains and fine grains into a weighing machine after sorting both of them to measure the wts. thereof. CONSTITUTION:When an apparatus is started after a predetermined wt. of specimen polished rice was thrown into a supply hopper 2, the crank shaft 5 of a sorting operation apparatus B and the sorting surface 3 having an uneven pattern of a disc body 4 is obliquely vibrated up and down at an angle larger than the elevation of the disc body 4. The whole grains having a large grain size in supplied polished rice are slid and flowed along the sorting surface 3 to be downwardly sent to a whole grain discharge part 13 and fine particles having a small grain size and an irregular shape are engaged with the sorting surface 3 to be upwardly sent to a fine particle discharge part 12. Sorted whole grains and fine grains are accumulated in weighing tanks and the wts. thereof are respectively weighed by a wt. measuring device 18. The measuring signals of the measuring device 18 are sent to a mixing ratio measuring apparatus 19 where the mixing ratio of fine grains is operated and displayed. By this method, measurement can be performed automatically.
