Cereal grade analyzer

Abstract

A device applied to the corn quality grade detecting, especially applied to imports and exports , the department of store and transportation , purchase, detect and production ,to detect the moisture content etc., bulk density and quality grade of corn such as maize and wheat, including moisture detect element, weighing element, volume measure element , vibration transport element, charging hopper , outer covering , computer data handling element etc. Its characteristic is that transporting the material waiting for detecting to volume measure element by using mini-type vibration transport device equably, ascertain the quality grade of the corn according to the real bulk density and moisture content of the corn entering volume measure element. Putting the material waiting for measuring into a charging hopper first, transducing the moisture content and temperature of the material by interdigited capacitor counter electrode in the inner side of charging hopper's back, the measure result is transmitted to the computer data handle element by the highway; The tiny vibrator works to make the silo resonating under the shaking excitation , the material in charging hopper drop into capacity cups equably from the silo and the take-up pan, close the mains switch after the capacity cups is full of material, inserting the flashboard into the slot under the take-up pan, taking away the unnecessary material lightly from the take-up pan, the slot and the pan; After the electronic scale is stable, reading the quality and the bulk density of the material waiting for measuring from the electron digital display, transmitting the result of the quality and the bulk density to the computer data handling element by the highway at same time; Finally, the computer data handling element decides the grade of the corn according to national standard GB1353 , GB1351, and the information such as moisture content , the temperature , the bulk density.

Description

1. Technical field [0001] The invention relates to a grain quality grade detection device, especially used for the detection of moisture and bulk density and quality grade judgment of corn, wheat and other grain import and export ports, storage and transportation, purchase, commodity inspection and processing departments. 2. Background technology [0002] Grain grading inspection is based on quality-based pricing, price discount and quantity increase, and price increment, which is directly related to the economic interests of both sides of the trade. The national standard of the People's Republic of China - corn GB1353-1999 changed the grading of pure grain rate to the grading of volume weight. Unify the moisture index to no more than 14.0%, and increase the imperfect kernel index to no more than 5.0%. At present, except for some indicators such as moisture and bulk density, which can be inspected by instruments, other indicators such as imperfect grains and impurities are ...
