Grain aflatoxin and external defect high-flux sorting machine

Abstract

The invention discloses a grain aflatoxin and external defect high-flux sorting machine, and belongs to the field of sorting. A photoelectric box is installed on the rear portion of a main machine frame, a high-flux online removing device rotating forwards and backwards by 180 degrees is installed in the middle of the photoelectric box, a front material box and a rear material box are arranged below the high-flux online removing device, a horizontally-arranged high-speed belt set is arranged in front of the high-flux online removing device, a sliding groove, an adjustable hopper and a feeding box are sequentially arranged above the front end of the high-speed belt set from bottom to top, and the lower end of the adjustable hopper is fixedly connected with a vibration feeder; a toxic raw material fluorescence detection device is arranged right above the high-speed belt group; and a raw material external quality sorting device mounted in the photoelectric box is arranged outside an outlet behind the high-speed belt group. According to the grain aflatoxin and the external defect high-flux sorting machine, toxin-containing grains can be detected, damaged inferior grains and impurities can be synchronously removed, the sorting machine has the advantages which a traditional color sorter cannot be compared with, and the problem of high-flux real-time online sorting of the toxin-containing grains is solved.

Description

technical field [0001] The invention belongs to the technical field of sorting, in particular to a high-throughput sorting machine for grain aflatoxins and external defects. Background technique [0002] In view of the objective existence and serious harm of harmful biotoxins in bulk grains and nuts and other food raw materials at ports, although the photoelectric color sorter based on visible light images that has been initially deployed at the customs can detect abnormal heterochromatic particles, it cannot Obtain the biochemical information inside the object, so it is impossible to identify poisonous grains without obvious appearance symptoms, and it is even more powerless to remove scattered poisonous and damaged low-quality grains from imported bulk grain raw materials at high speed and online synchronously. However, there is no equipment on the market that can perform high-throughput online sorting of food materials containing biotoxins. Therefore, research and design...

Problems solved by technology

[0005] In order to solve the problems that the existing traditional color sorter cannot realize the detection of food raw materials containing harmful biological toxins inside, the traditional air-blowing rejecting device needs a large-volume air compressor to assist air blowing, and the nozzles are easy to block and need to be manually cleaned frequently, the present invention provides A high-throughput sorting machine for grain aflatoxins and external defects is disclosed, which is characterized in that it includes: a main frame, a high-speed belt set, a fluorescent detection device for toxic raw materials, a raw material external quality sorting device, and high-throughput online elimination device, power supply system, material box, photoelectric box and industrial computer, wherein the main frame used to provide support for the photoelectric box, material box, high-speed belt set and adjustable feeding device is set on the ground; the photoelectric box is installed on the main frame At the rear, the middle part of the photoelectric box is equipped with a high-throughput online rejecting device that rotates forward and backward 180 degrees. There are two front and rear material boxes under the high-throughput online rejecting device; High-speed belt set, the top of the front end of the high-speed belt set is provided with a chute, an adjustable hopper and a feeding box in sequence from bottom to top, the lower end of the adjustable hopper is fixedly connected with the vibrating feeder, the vibrating feeder, the chute and the feeding box The box is fixedly connected to the main frame; a fluorescent detection device for toxic raw materials is installed directly above the high-speed belt group; and an external quality sorting device for raw materials installed in the photoelectric box is installed outside the rear exit of the high-speed belt group;
