Background technology
Packaging material for food with the contact process of food in, the chemical substance that is contained in material migration meeting in food causes negative effect to the quality of food with safety, and health is worked the mischief.The food-safety problem that the migration of chemicals causes in the packaging material for food occurs already and is paid close attention to by people day by day.
The U.S. has just begun to pay close attention to and research wrappage migration problem as far back as the sixties in 20th century.(Food and Drug Administration FDA) has formulated a series of relevant decree rules and skeleton instructions: some chemicals composition has been stipulated the specific transfer limit to this problem EU Committee (EU) and FDA (Food and Drug Adminstration); For the detection that makes harmful chemical becomes convenient, according to food properties food is classified, stipulated that a series of food analogies replace the food research experiment; According to the actual service conditions of food, provided and quickened the suitable temperature and time scope of migration test and the test and analysis technology of a lot of chemical substances.Patent CN101614726 discloses device for detecting migration volume of chemical substances in a kind of packaging material for food, is the cylindrical cup-shaped container that has seal groove and O-ring seal, is not easy to make.
The utility model content
The utility model provides a kind of extractor, is used to detect the migration amount that is in contact with one another material, especially for the migration amount that detects chemical substance in the packaging material for food.
A kind of extractor of detection material migration amount; Stainless steel base plate (1) with holes is gone up and is placed teflon gasket one (2) with holes; Teflon gasket one (2) with holes is gone up and is placed stainless steel groove (3); Stainless steel groove (3) is gone up and is placed teflon gasket two (4) with holes; Go up placement stainless steel cover plate (5) with holes at teflon gasket with holes two (4); Pass stainless steel base plate (1) with holes, teflon gasket one (2) with holes, teflon gasket two (4) with holes and stainless steel cover plate (5) with holes with supporting bolt (6) and tighten fixingly, be provided with liquid in stainless steel groove (3) side and inject, pour out device (7).
It is liquid injection, the pouring spout (8) that is provided with in stainless steel groove (3) side more than 1 or 1 that liquid injects, pours out device (7), and liquid injects, pouring spout (8) is provided with supporting sealing nut (9).
The utility model advantage is simple in structure, is material with the corrosion resistant plate, makes easily, can use by single or double, and two-sided use can improve extraction efficiency, can also once accomplish the extraction of the common migration thing of two kinds of testing samples simultaneously.
