predetermined set value will be led to increase in the residual content such as ash content, which is not permissible. In another embodiment, decrease in the measured value than the predetermined set value will led to decrease in the residual content or ash content, which may be permissible. The determination of the residual content will often lead to determination of the grade quality of the food product. Further, if the percentage of the residual content is more than the predetermined values, then the grade quality will be low and vice versa. The plurality of indicators, or arrow mark 204 could be at least one of increases in the measured value, decrease in the measured value, equality between the measured and predetermined value.
FIG. 3 exemplarily illustrates a general arrangement of a diverting member 300 corresponding to the milling apparatus, according to an embodiment as disclosed herein. After determining the grade quality of the food product by a computation member 200, the food product is fed into the diverting member 300.

BACKGROUND
The invention disclosed herein, generally relates to a method and an apparatus for measuring residual content such as an ash content of a food product. In known art of wheat milling process, the percentage of ash content is an important factor for deciding the quality and yield of the end product. The consumer or a customer may provide a requirement of certain limit of ash percentage to the milling industry and the milling industry is financially penalized if the limit of ash is exceeded. For the above reason, the mill industry may produce flour or food product below the limit of ash content. If the ash percentage is too low in relation to the limit provided by the customer, then the milling industry have less benefit and thereby less profit. The ash percentage is directly connected to the grinding percentage (yield). It is a difficult process to manually adjust the ash percent to be in the limit and the conventional systems are not able to provide 100% optimization.
Generally, a wheat grain mill is implemented with several grinding stages. After each grinding stage, the entire product is sifted and the flour is guided out via a flour passage in the milling apparatus towards the storage container. The finished flour is collected or transferred to a collection auger from all milling stages via pipes. While nearing the end of the milling process, the ash percentage is darker in which equal to a higher ash percentage. It is also difficult to mark the flour quality in different grade depending on the ash percentage and divert the same to respective chambers.
Hence, there is a long felt but unresolved need for an apparatus, which determines the ash percentage, measure the grade quality of the food product, and divert the flour according to the grade quality.
