Problems solved by technology

[0004] For liquid food, it is prone to sedimentation, which leads to inconsistent composition of each depth layer. The current sampling method is to stir evenly before sampling, or to mix after multiple layered samples, but this method is not suitable for storage. Liquid food in large tanks is not suitable, and the operation is troublesome and time-consuming

Embodiment

[0047] see Figure 1-8 , a bottom-inductive liquid food detection method, see Figure 8 , including the following steps:

[0048] S1, first detect the depth of the liquid food to be sampled, and estimate the approximate hydraulic range based on this, and adjust the pressure device of the layered sampling ball accordingly;

[0049] S2, put the adjusted layered sampling ball into the liquid food, the layered sampling ball first sinks to the bottom, and then slowly floats up, and completes the sampling during the process of floating;

[0050] S3, after the layered sampling ball floats to the liquid surface, take it out, and finally pour out the sampling liquid for testing;

[0051] see figure 1 , the layered sampling ball in the S1 step includes a buoyancy ball 1, and the inside of the buoyancy ball 1 is provided with a sample storage cavity 2, and the inner wall of the sample storage cavity 2 is fixedly connected with a plurality of upper and lower distribution partition plat...

Abstract

The invention discloses a bottom detection induction type liquid food detection method, and belongs to the field of food detection. The method comprises the steps that a stratified sampling ball is put into liquid food, and after the stratified sampling ball sinks to the bottom of the liquid, a hydraulic induction trigger on the sampling ball is pressed down through hydraulic pressure to pierce a liquid storage ball film to release diluted hydrochloric acid; a buoyancy air bag is expanded through the chemical reaction of hydrogen generated by diluted hydrochloric acid and aluminum, then the sampling ball begins to float upwards, a starting valve plate is opened while floating upwards to achieve the sampling purpose, the starting valve plate is continuously opened along with continuous enlargement of the buoyancy air bag, sampling is completed while the sampling ball floats upwards, and therefore stratified sampling is achieved; and the samples in different layers are placed in one area, so that the samples can be separately detected and can also be uniformly detected after being mixed.

Description

technical field [0001] The invention relates to the field of food detection, and more specifically relates to a detection method for bottoming-out induction type liquid food. Background technique [0002] The content of food inspection is very rich, including analysis of food nutritional components, analysis of contaminants in food, analysis of food auxiliary materials and food additives, food sensory identification, etc. Food inspection in a narrow sense usually refers to the inspection of food quality conducted by food inspection agencies in accordance with the hygienic standards stipulated in the "Food Sanitation Law of the People's Republic of China", including the inspection of food outer packaging, inner packaging, signs, marks and commodity appearance. Characteristics, physical and chemical indicators, and other inspections of health indicators. The inspection methods mainly include sensory inspection and physical and chemical inspection. [0003] The indicators of ...
