Apparatus for continuously measuring the degree of milling of grains

An apparatus for continuously measuring the degree of milling of grains comprising

• a light source unit directing light to be reflected by and transmitted through the grains,
• a grain passage unit disposed in the path of said light and having a first wall disposed at the near side from said light source unit and a second wall disposed at the far side from said light source unit,
• a reflected light detecting unit having a reflected light sensing element positioned adjacent to said first wall,
• a transmitted light detecting unit having a transmitted light sensing element adjacent to said second wall,
• an arithmetic unit connected to said reflected light detecting unit and said transmitted light detecting unit,
• a degree of milling meter connected to said arithmetic unit,
• a first integrated data take-up unit connected to said reflected light detecting unit, and
• a second integrated data take-up connected to said transmitted light detecting unit,
• said first integrated data take-up unit and said second integrated data take-up unit being connected to said degree of milling meter through said arithmetic unit whereby the integrated data obtained in a given period divided into a number of divisions is averaged to calculate the degree of milling being sought.
