Description
[technical field]
The utility model is about a kind of food inspection device, is meant a kind of large scale or difficult Food Contact product simulation migration test pond of boring pilot hole of being used for especially.
[background technology]
Scientific research is the result show, become one of important source of food pollution with harmful element, objectionable impurities in the tableware of Food Contact and packing container and the wrappage, so food contact material safety and sanitation problem caused the great attention of various countries.Various countries particularly developed countries such as European Union, Japan, the U.S. have formulated corresponding packaging material for food rules system one after another, and the safety and sanitation of food contact material are strict with.In the standard of the food contact material rules of various countries, the safety and sanitation accordance evaluation of food contact material is mainly carried out through the simulation migration test.Most of rule and standard all explicitly call for simulation test the simulated foods contact material are actual as far as possible and carry out with the Food Contact situation, like material and the goods to the single face contact food, only allow to test the migration situation of contact food one side during simulation test.Most of food contact material all is the single face contact food, for material that can hold analogies and goods, can directly analogies be added in the goods and test.Also require test process will reduce the analogies loss but then be difficult to test, particularly rule and standard for food contact materials such as tabular, plate-shape and films as far as possible, so migration test difficulty comparatively, need be undertaken by special device.It is reported, do not see above-mentioned migration test device sale in the market, do not carry out the research of such device and simulation experiment method thereof with also seeing manned system.
Owing to lack corresponding migration test device; The analogies of Food Contact product and Ceramic Tiles be difficult to directly hold to(for) tabular, plate-shape, film etc.; Full immersed method test is still adopted in most of domestic laboratory at present; This method not only sample produce difficulty, but the actual operating position that such test result can not accurate response Food Contact product.
The measuring technology of food contact material is provided in the prior art, is 2010.11.03 day as disclosing day, and publication number is the Chinese patent " food contact material simulation migration test pond " of CN201622227U; Its description be: this test tank comprises the test tank main body, and said test tank main body comprises ccontaining pond, O-ring seal, base, and locked instrument; The sheet sample of food contact material is placed on the said base; The ccontaining pond opening of said band O-ring seal is pressed on the surface of sheet sample of food contact material down, also comprises upper cover plate, and said upper cover plate covers on said ccontaining pond; Said ccontaining pond is the tubbiness of an end opening; On the outside, bottom surface in ccontaining pond a catheter is set, said catheter is communicated with ccontaining pond inner chamber, offers a through hole on the said upper cover plate; Said catheter passes said through hole, through locked instrument upper cover plate and base is locked together.This test tank can accurately reflect the actual operating position of food contact material; But during for the sample migration tests such as tabular, plate-shape of hardness big (like plastics, metal, pottery, bamboo and wood materials), size big (effective diameter is greater than apparatus main body); Sample splits when boring pilot hole easily, causes test tank can't accomplish the test of sample.
