Multi-station external-clamping-type simulation migration testing tank

Abstract

The invention relates to a multi-station external-clamping-type simulation migration testing tank which comprises a testing tank main body and a bracket. The testing tank main body is arranged on the bracket; the testing tank main body comprises a liquid charging hole cover, an accommodating tank and an external-clamping-type fixture; the external-clamping-type fixture consists of an upper clamp plate, a lower clamp plate, clamping bolts and nuts; the upper clamp plate is clamped in the accommodating tank; four peripheral sides of the upper clamp plate are provided with four open slots; a liquid catheter is arranged outside the bottom surface of the accommodating tank; the liquid catheter is communicated with an inner cavity of the accommodating tank; three through holes are uniformly formed on the upper clamp plate along the central axis; the liquid catheter passes through any one through hole; the liquid charging hole cover is screwed on the liquid catheter of the upper clamp plate; the accommodating tank is arranged on a test sample surface; the clamping bolts are arranged on the lower clamp plate; and the clamping bolts pass through the four open slots on the upper clamp plate and lock the upper clamp plate and the lower clamp plate through the nuts. Due to the adoption of the multi-station external-clamping-type simulation migration testing tank, the actual service condition of a food contact product can be accurately reflected and the problem of stimulation migration testing of a test sample which has a large-size or is difficult for drilling a locating hole is solved.

Description

【Technical field】 [0001] The invention relates to a food testing device, in particular to a food contact product simulation migration test pool for large-sized or difficult-to-drill positioning holes. 【Background technique】 [0002] Scientific research results show that harmful elements and substances in tableware, packaging containers and packaging materials that come into contact with food have become one of the important sources of food contamination. Therefore, the safety and hygiene of food contact materials has attracted great attention from all countries. Various countries, especially developed countries such as the European Union, Japan, and the United States, have formulated corresponding food packaging material regulatory systems to impose strict requirements on the safety and hygiene of food contact materials. In the standards of food contact material regulations in various countries, the safety and hygiene compliance evaluation of food contact materials is mainly...

Problems solved by technology

The test cell can accurately reflect the actual use of food contact materials, but for samples with large hardness (such as plastic, metal, ceramics, bamboo and wood materials) and large size (effective diameter larger than the main body of the device), the migration During the test, the sample is easy to crack when drilling the positioning hole, which makes the test cell unable to complete the test of the sample
