Abstract

The invention discloses an intelligent agricultural product sorting machine with an aflatoxin detection function. The device takes an aflatoxin sorting detection unit as a core, and an ultraviolet and visible light source, a dual-wavelength filter set, a double-mirror reflecting system and a linear-array CCD camera and the like are arranged in the sorting detection unit. Materials are conveyed to the sorting detection unit by a crawler conveyor, the linear-array CCD camera acquires visible light images of the materials and two ultraviolet fluorescence images shot by filters, and the on-line detection of aflatoxin contaminated grains is realized by using a computer detection algorithm. The wavelengths of double filters used in the invention are determined by using a hyperspectral imaging method, and different filters can be replaced for detecting different agricultural products, particularly, the filters with the wavelengths of 437 and 537nm can be used for detecting corns, the filters with the wavelengths of 420 and 450nm can be used for detecting peanuts, and the filters with the wavelengths of 400 and 420nm can be used for detecting hot peppers. The device can be widely used in the field of processing trade of agricultural products, and the on-line aflatoxin inspection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to an intelligent sorter for agricultural products with aflatoxin detection function. Background technique [0002] Aflatoxin is a chemical substance with a strong carcinogenic effect, and it is easy to grow on food crops. Among them, corn, agricultural products, peppers and their products have the highest aflatoxin content and are highly susceptible to infection. The levels of aflatoxin in various countries are strictly restricted. However, due to the aflatoxin pollution caused in the process of planting and storage, the normal export of agricultural products and their products in my country has been seriously affected, resulting in large economic losses. [0003] The existing color sorter for agricultural products adopts ordinary light source to irradiate, and according to the difference in the optical characteristics of the surface of agricultural products, the moldy, da...
