Problems solved by technology

Conversely, when the water content of the sample is high, since its viscosity also becomes high, the use of a constant rotating impeller will cause the sample to be rotated and transported irregularly, and the filling density of the sample measurement part will not be maintained constant, and it is easy to Variation in Assay Results Occurs

Embodiment Construction

[0031] Preferred embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

[0032] Figure 1 to Figure 4 An example of the grain quality measuring device of the present invention is shown. Such as figure 1 As shown, the grain quality measurement device 1 includes a box-shaped frame 2, a hopper 3 arranged on the upper surface of the frame 2, and an opening / closing gate (not shown) arranged in an opening formed on the bottom of the hopper 3 .

[0033] The impeller 4 is arranged below the opening formed on the bottom of the hopper 3, and the opening formed on the upper surface of the casing 4a of the impeller 4 communicates with the bottom opening of the hopper 3 via a gate. The gate passes through the control device 15 ( figure 2 The solenoid 5 operated by the control signal of ) is activated and rotated downward, and the sample (grain) thrown into the hopper 3 can be supplied to the impeller 4 . The impeller 4 has a ...

Abstract

Provided is a device for measuring the quality of grains which is capable of obtaining stable measurement results with ease, without being affected by the shape of the grains, by enabling the rotationspeed of an impeller to be changed in accordance with the shape of the grains to be measured. The present invention is characterized by being provided with: a hopper which is provided to an upper part of a housing, and into which grains are introduced; an impeller which conveys the grains introduced into the hopper by rotating said grains; a sample measurement unit which is provided below the impeller, and which can be filled with a prescribed amount of grains; a measurement means which optically measures the quality of the grains in the sample measurement unit; and a control device which iscapable of changing the rotation speed of the impeller in accordance with the shape of the grains introduced into the hopper.

Description

technical field [0001] The present invention relates to a grain quality measurement device for optically measuring, for example, the taste and internal quality of grains. Background technique [0002] In the past, in quality measuring devices such as a taste analyzer for analyzing the taste of grains and an internal quality measuring instrument for measuring the internal quality of grains, the quality of samples (for example, grains) was measured by putting them into the device frame. The sample in the hopper on the upper part of the body is rotated by an impeller connected to the bottom of the hopper and supplied (filled) to the measurement part, and then the sample is measured using optical analysis such as near-infrared analysis. Moreover, the quality evaluation apparatus of the unhulled rice using a near outer line analyzer is disclosed, for example in the following patent document 1. [0003] [Prior Technical Literature] [0004] 〔Patent Document〕 [0005] [Patent Do...
