Sampling device for liquid food detection

Abstract

The invention discloses a sampling device for liquid food detection, and relates to the technical field of food detection and sampling. The sampling device comprises a sampling container, a sampler fixing piece and an operating rod, wherein the sampling container comprises a lower cylinder and an upper cylinder which are connected in a sealing fit manner; a waved plate is arranged on the upper cylinder body, and an air cavity is formed between the upper cylinder body and the waved plate; an opening for communicating the air cavity with the lower cylinder is formed in the bottom end of the waved plate; a liquid inlet joint A and an air outlet joint A are respectively arranged on the upper cylinder body on the two sides of the waved plate; the sampler fixing part comprises a fixing column, asupporting plate is arranged on one side of the fixing column, and a sampling cover cylinder used for containing the sampling container is arranged on the supporting plate. An end cover is arranged at the top of the sampling cover cylinder. With cooperative use of the sampling container, the sampler fixing piece and the operating rod, sampling samples of liquid at different depths can be obtainedthrough one-time operation in operation, and the sampling operation is simple.

Description

technical field [0001] The invention belongs to the technical field of food testing and sampling, in particular to a sampling device for liquid food testing. Background technique [0002] In food safety testing, it is often necessary to sample liquid food such as edible oil or beverages. The traditional sampling method is generally to use a sampling spoon or a cup-type liquid sampler to sample, that is, to use a sampling spoon to sample on the surface of the liquid or to After the sampling cup is closed, probe into the liquid and open the mouth of the sampling cup to take samples. The disadvantages of these two methods are: sampling with a sampling spoon can only take samples on the surface of the liquid, and the representativeness of the samples is not high. Since food sampling requires multi-point sampling, Therefore, the sampling method of the sampling cup needs to be sampled multiple times and then the multiple samples after sampling are mixed for analysis. The food to b...
