Abstract
The rapid detection apparatus of portable food sulfur content, relates to a kind of SO
2the detecting instrument of content, it is characterized in that: comprise heating net, suction fan, sulphur sensitization material sensors, data processing chip, battery, shell, display screen and switch, shell is strip hollow-core construction, heating net is arranged on the front end of shell, suction fan, sulphur sensitization material sensors, data processing chip and battery are contained in the inside of shell, shell is provided with display screen, switch and vent port, sulphur sensitization material sensors and data processing chip electrical connection, data processing chip and display screen electrical connection.Advantage is: can be used for the harmful sulfur content detected fast in food, simple to operate, be easy to learn and use, and instrument is small and exquisite, is convenient for carrying, and often uses, and can to exceed standard food by Timeliness coverage sulphur, avoids or reduce the harm of sulfur-bearing food to health that exceeds standard; The utility model, as the portable instrument detecting food sulfur content fast, can be widely used in family, dining room and market surpervision department etc.
Description
Technical field
The utility model relates to a kind of Portable rapid detector device of sulfur content, is specifically related to a kind of food SO
2the detecting instrument of content.
Background technology
Existing food sulfur content detecting instrument great majority are used by foods supervision mechanism, method is confined to the classic method such as spectrophotometric method and gas liquid chromatography, and mostly can only be used for a group food, such as bird's nest, oat sulfur dioxide detector, because pretreatment time is longer, sensitivity is relatively low, instrument volume is larger, additional expensive, so be difficult to realize miniaturization, be more difficult to spread to family expenses detection-phase.China's related food adjuvant uses in hygienic standard and specifies, the content of sulfur dioxide of biscuit, sugar, bean vermicelli, can must not more than 50 mg/kg, and other kinds must not more than 100 mg/kg.If sulfur fumigation food is industrial sulphur, will occur serious poisoning after people's food.Sulphuric dioxide can become sulphurous acid after meeting water, enters human body and not only destroys food vitamins B1, affect the absorption of human body to calcium, and the free stomach and intestine of sulphurous acid to people also have spread effect.If frequent this based food edible, beyond doubt by chronic poisoning! Therefore market is badly in need of now a kind of portable, easily universal detecting instrument to detect fast.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of small portable, fast sulfur dioxide detector device, and this instrument is easy to operation, can simplify testing process.
In order to solve the problems of the technologies described above, the utility model provides a kind of rapid detection apparatus of portable food sulfur content, it is characterized in that: comprise heating net, suction fan, sulphur sensitization material sensors, data processing chip, battery, shell, display screen and switch, shell is strip hollow-core construction, heating net is arranged on the front end of shell, suction fan, sulphur sensitization material sensors, data processing chip and battery are contained in the inside of shell, shell is provided with display screen, switch and vent port, sulphur sensitization material sensors and data processing chip electrical connection, data processing chip and display screen electrical connection.Its principle produces sulphuric dioxide SO by the heating of heating net contact food
2gas, is sucked by suction fan, after the absorption of sulphur sensitization material sensors, is detected and changes into electric signal, sulfur content data exported and show on a display screen by data processing chip.
Further, described data processing chip is OM8380H display and data processing chip, and this chip is the high-end TV/ monitor video Graphics Processing integrated circuit that PHILIPS company develops.
Further again, described sulphur sensitization material sensors sensitive coating part is containing the chromium trioxide of palladium and the nano-material coating of aluminium oxide.
Further again, the monnolithic case of described shell is the form of a stroke or a combination of strokes, and switch is at top.
During use, first make heating net contact food surface, press play button and heat, SO
2gas can be sucked by suction fan, by sulphur sensitization material sensors, sensor receive sulphuric dioxide generation weak current change produce electric signal, electric signal by OM8380H show and data processing chip process output display on a display screen, can immediately read.
The utility model compared with prior art, advantage is: can be used for the harmful sulfur content detected fast in food, raise the efficiency, and use and do not need specialty background, simple to operate, be easy to learn and use, instrument is small and exquisite, be convenient for carrying, frequent use, can to exceed standard food by Timeliness coverage sulphur, avoids or reduce the harm of sulfur-bearing food to health that exceeds standard; The utility model, as the portable instrument detecting food sulfur content fast, can be widely used in family, dining room and market surpervision department etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
As shown in Figure 1, the utility model comprises heating net 1, suction fan 2, sulphur sensitization material sensors 3, data processing chip 5, battery 6, shell 7, display screen 8 and switch 9, shell 7 is strip hollow-core construction, heating net 1 is arranged on the front end of shell 7, suction fan 2, sulphur sensitization material sensors 3, data processing chip 5 and battery 6 are contained in the inside of shell 7 from front to back successively, shell 7 is provided with display screen 8, switch 9 and vent port 4, sulphur sensitization material sensors 3 and data processing chip 5 are electrically connected, and data processing chip 5 and display screen 8 are electrically connected; The monnolithic case of shell 7 is the form of a stroke or a combination of strokes, and switch 9 is at top.Above-mentioned data processing chip 5 is OM8380H display and data processing chip preferably; Described sulphur sensitization material sensors 3 sensitive coating part is containing the chromium trioxide of palladium and the nano-material coating of aluminium oxide, by can cause the small variations of sensor current to the absorption of sulphur, OM8380H display and data processing chip 5 can detect electric signal and be translated into sulfide concentration numerical value, display screen can intuitively show detection data, user's reading displayed numerical value.In order to ensure to measure accurately, optionally taking food product different surfaces, being averaged by repetitive measurement.
