| titleOfInvention | Sulfite draws and absorbs detection device in food |
| abstract | The utility model discloses a sulfite draws absorbs detection device in food belongs to laboratory detection area. A device for extracting, absorbing and detecting sulfite in food comprises a magnetic heating stirrer, a heating switch and a stirring switch, wherein the top end of the magnetic heating stirrer is connected with a first reaction container, one end of the first reaction container, which is far away from the magnetic heating stirrer, is connected with a second reaction container, one end of the second reaction container, which is far away from the first reaction container, is connected with a condensation pipe, and the top of the condensation pipe is detachably connected with a U-shaped pipe; the utility model discloses magnetic force heating agitator work for the reaction liquid in the first container produces sulfur dioxide and rises to be absorbed by formaldehyde in the second reaction vessel, and sulfur dioxide and vapor continue to rise and can be cooled when passing through the cooling cylinder and flow back to the reaction in the second reaction vessel again, and the sulfur dioxide that continues to rise can get into U type intraductal absorption clean by its formaldehyde, takes out the absorption solution in first reaction vessel and the U type pipe after and operates the computer and survey. |
