A sample pretreatment device for food testing

Abstract

The invention discloses a sample pretreating device for food detection. The sample pretreating device for food detection comprises a bottom plate, a water tank, a crushing chamber and a mixing chamber, wherein the water tank is arranged at the upper end of the bottom plate; the right end of the water tank is fixedly connected with the mixing chamber; the crushing chamber is formed at the upper endof the mixing chamber; a feed port is formed in the upper end of the crushing chamber; a rotating motor is arranged on the right side of the feed port; the mixing chamber is communicated with the crushing chamber through a discharge port in the lower end of the crushing chamber; a movable plate is connected inside the mixing chamber in a sliding manner; stirring shafts are symmetrically arrangedat the upper end of the movable plate; a through hole is formed in the middle position of the movable plate; an electromagnetic valve is arranged inside the through hole; the lower end of the throughhole is communicated with a telescopic tube. The arranged movable plate moves downwardly under the action of gravity, and squeezes a press switch to close the discharge port and a water suction pump,so that quantitative mixing is achieved and the detection effect is improved; the arranged stirring shafts achieve rotating stirring when the movable plate moves up and down, so that a detection deviation due to sinking can be effectively eliminated and later detection is facilitated.

Description

technical field [0001] The invention relates to the field of food testing, in particular to a sample preprocessing device for food testing. Background technique [0002] Prospects for the food safety industry. At present, the food safety industry is facing opportunities for rapid development. First of all, food safety has become the focus of people's attention. From the experience of developed countries and regions, food safety problems are likely to occur when urbanization reaches a certain level. In recent years, many food safety incidents have occurred in China, which has aroused great concern from the people. , which provides an opportunity for the development of the food safety industry. Secondly, the development of the food safety industry has a favorable international environment, and food safety is a worldwide issue. [0003] Food detection is the best means of supervision. In order to improve the efficiency of detection, people have produced food detection equipme...

Problems solved by technology

[0003] Food detection is the best means of supervision. In order to improve the efficiency of detection, people have produced food detection equipment, but the detection process is cumbersome. In order to make detection fast and efficient, pretreatment is usually used. Ordinary pretreatment devices have poor processing effect and high efficiency. Low, affecting later detection, does not meet the needs of social development
