Multiple channel hand-held food safety detecting instrument

Abstract

This invention discloses a multiple-path hand detection device for food safety, which comprises light path, single machine and assistant circuit and IO parts. The single machine and the assistant circuit are used in computer and control and the IO part are used in information input and output and the said light path comprises light source constant-pressure control circuit, monochromatic light source set, multiple-path color matching pool, photoelectric detector set and signal adjusting circuit. The device is characterized by double current and convenience and it can at same time detects out organ ophosphorus, carbamate chemicals, aqua fortis, nitrite, lead cyanide, cyanide, formaldehyde and sodium sulfoxylate formaldehyde, etc. This device is capable of on-spot detection and data storage and acquirement and result copy.

Description

technical field [0001] The invention relates to a fast food detection technology, in particular to a multi-channel hand-held food safety detector. technical background [0002] In recent years, the contamination of food due to the abuse of pesticides, food and feed additives, plant and animal growth hormones, and environmental pollution has become very prominent. Dioxin pollution incidents of broiler chickens abroad have caused billions of dollars in economic losses; acute poisoning accidents caused by pesticide abuse in China have occurred from time to time; nitrite in pickled products and formaldehyde in soaked food in the market are seriously exceeded; excessive Hormone feeding of soft-shelled turtles and other aquatic products makes people unsafe to eat; excessive pollutants have caused huge economic losses to a large number of my country's export commodities. The abuse of pesticides, insecticides, food additives and hormones not only causes acute toxicity, but also has ...

Problems solved by technology

Some of these instruments use 220V power supply, are large in size, and need to be used in conjunction with a constant temperature water bath, and some can only measure one sample or one component at a time, which is not suitable for rapid analysis of multiple samples and components on site

In addition, a small number of manufacturers have introduced single-parameter detectors such as formaldehyde and nitrite, which cannot simultaneously measure multiple components, and most of them are desktop machines used in laboratories.

Jida Little Swan Company has recently launched a five-in-one food safety analyzer that can detect five harmful substances in food, nitrite and nitrate, sulfur dioxide, formaldehyde, pesticide residues, and white lumps, but only one can be measured at a time. sample, and it adopts a desktop design, which is suitable for use in the laboratory, and cannot realize on-site handheld analysis

[0005] At present, there is no multi-channel hand-held food safety detector that can quickly detect multiple toxic and harmful substances on multiple samples at the same time in China, and there are no reports of similar commercialized instruments abroad.
