Embodiment 1

[0029] Please refer to Figures 1-3, a metal detection device for edible fungus detection for food quality and safety testing, including a heavy metal detection device 5, a distribution device 3 is installed in the middle of the heavy metal detection device 5, and the top of the distribution device 3 is connected to a feed Device 1, a stirring device 2 is installed inside the feeding device 1 .

[0030] The feeding device 1 comprises a mixing drum 101, the top of the mixing drum 101 is welded with a feeding drum 102, the outside of the feeding drum 102 is plugged with a feeding hopper 103, the inside of the mixing drum 101 is welded with a spiral iron sheet 104, and the spiral iron The top of the sheet 104 is located below the outlet of the feed hopper 103 , and the bottom of the mixing drum 101 is welded with a discharge hopper 105 .

[0031]Stirring device 2 comprises motor 201, and motor 201 is threadedly installed on the top of feeding cylinder 102, and the output end of mo...

Embodiment 2

[0034] Please refer to Figures 4-6, the difference in connection with the basis of Embodiment 1 is that the material distribution device 3 includes an outer cover 301 and a material distribution pipe 302, the outer cover 301 is positioned at the outside of the discharge hopper 105, and the material distribution pipe 302 is provided with four , the cross-section of the four distribution pipes 302 is fan-shaped and can be combined into a complete circle, the outer side of the distribution pipe 302 is connected with the discharge pipe 303, the inside of the distribution pipe 302 is provided with a lifting plate 304, and the lifting plate 304 The outer side is in frictional contact with the inner wall of the material distribution pipe 302, the bottom of the material distribution pipe 302 is welded with a base plate 308, and the top outside of the material distribution pipe 302 is provided with an inlay groove 307, and the inlay groove 307 is fitted with a mobile control board 305 to...

Embodiment 3

[0038] Please refer to Fig. 1, the difference in combination with the basis of embodiments 1 and 2 is that heavy metal detection device 5 includes graphite furnace atomic absorption spectrometer A501, atomic fluorescence spectrometer A502, graphite furnace atomic absorption spectrometer B503 and atomic fluorescence spectrometer B504, four Two spectrometers surround the material distribution device 3 and their material inlets are all connected to the outlet of the discharge pipe 303 .

[0039] The invention mainly detects lead, cadmium, mercury and arsenic in edible fungi. Lead in edible fungi is detected by graphite furnace atomic absorption spectrometer A501, and graphite material is used to make tubes, cups and other shapes of atomization. The instrument uses current heating atomization to carry out atomic absorption analysis, which has the advantages of high efficiency and high sensitivity, and can reach the ppb level. The graphite furnace atomic absorption spectrometer B503...

Abstract

The invention discloses an edible mushroom detection metal detection device for food quality safety detection, and belongs to the technical field of food safety. The edible mushroom detection metal detection device for food quality safety detection comprises a heavy metal detection device, a material distribution device is installed in the middle of the heavy metal detection device, the top of the material distribution device is connected with a feeding device, and a stirring device is installed in the feeding device. The problem that the metal detection device on the market at present cannot detect the content of various heavy metals at a time is solved.

Description

technical field [0001] The invention relates to the technical field of food safety, in particular to an edible fungus detection metal detection device for food quality and safety detection. Background technique [0002] Heavy metals are ubiquitous in people's daily life. All foods contain heavy metals to a greater or lesser extent. Heavy metals are ubiquitous in all foods, and edible fungi are no exception. Because heavy metal is an environmental pollutant, it is ubiquitous in the environment, such as air, water, and soil. However, our food cannot be separated from the environment in the process of planting, breeding, production, processing, transportation and storage, and it is naturally difficult to eliminate heavy metals. The accumulation of heavy metals in edible fungi is only a self-protection mechanism of edible fungi against adverse growth environments, and is not an inevitable result of the growth of edible fungi. Edible fungi will produce some proteins that can co...
