CN105548088A - Method for rapidly identifying appearance quality of rice - Google Patents

Abstract

The invention discloses a method for rapidly identifying the appearance quality of rice. The method comprises the following steps: (a) selecting a tea table with transparent glass, and vertically placing a flashlight on an interlayer below the glass of the tea table; (b) processing the rice into hulled rice by virtue of a rice huller, and selecting and flatly arranging 100 hulled rice grains on the glass with the light source; (c) turning on the flashlight light source, picking out chalky hulled rice, and dividing the number of the chalky hulled rice by the total number 100 of the hulled rice to obtain a numerical value, i.e. a chalky grain rate; (d) flatly arranging the chalky hulled rice on the glass with the light source, visually observing the proportion of a chalk area to the whole area of the rice, and multiplying the proportion by the chalky grain rate to obtain a numerical value, i.e. chalkiness; (e) placing the 100 hulled rice grains on the glass with the light source, and visually observing the transmittance, i.e. transparency, of the rice. According to the method, the three indexes of the chalky grain rate, the chalkiness and the transparency can be detected only with the transparent glass and the flashlight, and the method is simple, easy and low in detection cost, and the materials are highly available.

Description

A kind of method of Rapid identification Appearance Quality of Paddy Rice

Technical field

The present invention relates to agricultural production, particularly relate to a kind of method of Rapid identification Appearance Quality of Paddy Rice.

Background technology

There is Three Standards in country to Appearance Quality of Paddy Rice, i.e. chalky grain rate, chalkiness degree and transparency.The analytical instrument of these three index specialties detects.Prior art is really accurate in qualification result, but needs the analytical instrument of specialty, and qualification process is too complicated, and short time consumption is long, is unfavorable for application in some cases.

Summary of the invention

Invent problem to be solved to be: a kind of method providing Rapid identification Appearance Quality of Paddy Rice, it is low that it has appraisal cost, identifies feature fast.

Technical solution problem of the present invention adopts following technical scheme:

A method for Rapid identification Appearance Quality of Paddy Rice, is characterized in that, comprises the following steps:

A, select a tea table having clear glass, flashlight upright be placed on the interlayer below tea table glass,

B, with hulling machine, paddy processing is become brown rice, choose 100 brown rice, yaw is on the glass having light source, and rice is not overlapping;

C, open electric torch light source, light is to upper direct projection, according to " brown rice printing opacity, the light tight formation shade of the white part of chalk in brown rice " principle, choose the brown rice having chalk white, the brown rice quantity having chalk white is divided by brown rice sum 100, the numerical value obtained is chalky grain rate, chalky grain rate be less than 10% be 1 grade of rice, chalky grain rate be 11% ~ 20% be 2 grades of rice, chalky grain rate be 21% ~ 30% be 3 grades of rice, chalky grain rate be more than 30% for rice inferior;

D, the brown rice yaw having chalk white on the glass having light source, range estimation chalk fine flour is long-pending accounts for whole rice area ratio, is multiplied by the numerical value that chalky grain rate obtains and is chalkiness degree; Chalkiness degree is 1 grade of rice below 1%; Chalkiness degree is 2 grades of rice below 3%; Chalkiness degree is 3 grades of rice below 5%; Chalkiness degree is rice inferior more than 5%;

E, 100 brown rice pendulum on the glass having light source, the printing opacity degree of range estimation rice, is transparency, printing opacity be 1 grade of rice, lighttight is 3 grades of rice, and in-between is 2 grades of rice.

The invention has the beneficial effects as follows: the present invention on the basis of existing technology, only need can out simple for chalky grain rate, chalkiness degree and transparency three Indexs measure with clear glass and electric torch, draw materials conveniently, do not need to buy instrumentation, Detection results is accurate.

Embodiment

Below in conjunction with specific embodiment, the present invention is described in further details:

Embodiment 1

A, select a tea table having clear glass, flashlight upright is placed on the interlayer below tea table glass;

B, with hulling machine, paddy processing is become brown rice, choose 100 brown rice, yaw is on the glass having light source, and rice is not overlapping;

C, open electric torch light source, light is to upper direct projection, according to " brown rice printing opacity, the light tight formation shade of the white part of chalk in brown rice " principle, choose the brown rice having chalk white, the brown rice quantity having chalk white is divided by brown rice sum 100, the numerical value obtained is chalky grain rate, chalky grain rate be less than 10% be 1 grade of rice, chalky grain rate be 11% ~ 20% be 2 grades of rice, chalky grain rate be 21% ~ 30% be 3 grades of rice, chalky grain rate be more than 30% for rice inferior;

D, the brown rice yaw having chalk white on the glass having light source, range estimation chalk fine flour is long-pending accounts for whole rice area ratio, is multiplied by the numerical value that chalky grain rate obtains and is chalkiness degree; Chalkiness degree is 1 grade of rice below 1%; Chalkiness degree is 2 grades of rice below 3%; Chalkiness degree is 3 grades of rice below 5%; Chalkiness degree is rice inferior more than 5%;

E, 100 brown rice pendulum on the glass having light source, the printing opacity degree of range estimation rice, is transparency, printing opacity be 1 grade of rice, lighttight is 3 grades of rice, and in-between is 2 grades of rice.

The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
