Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a food microorganism separation and detection device. Background Art

[0002] Food microorganisms are the main factor causing food corruption and deterioration. People have continuously summarized various food preservation methods in their lives to avoid the growth of microorganisms in food and accelerate food deterioration. However, microorganisms are everywhere in our lives. In the face of harmful microorganisms, it is necessary to conduct microbial testing on the produced food.

[0003] The microbial separation device in the prior art has a complicated separation process and many operating steps, which reduces the efficiency of microbial detection. It is also inconvenient to disinfect and clean the microorganisms after separation, which affects the next separation result. Therefore, we propose a food microbial separation and detection device to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A food microorganism separation and detection device comprises a base and a crushing tank, wherein a support plate is fixedly arranged on the top of the base, a control panel is fixedly arranged on the top of the support plate, a hollow track is provided on the support plate, slide grooves are provided on both sides of the hollow track, two slide grooves are slidably connected with the same slider, a fixed pipe is fixedly connected to the bottom of the slider, the crushing tank is arranged on the top of the base, a filter barrel is arranged inside the crushing tank, and the fixed pipe is located directly above the crushing tank, and the device further comprises:

[0007] A stirring component, which is arranged on the slider and is used to stir the food in the crushing tank;

[0008] The driving assembly is arranged on one side of the supporting plate and is used to drive the slider to move up and down automatically, so as to facilitate the stirring of the food in the crushing tank;

[0009] A fixing component is arranged on the top of the base and is used to fix the crushing tank on the base to facilitate stirring.

[0010] In one possible design, the stirring assembly includes a first motor, which is fixedly arranged on the top of the slider, and the output end of the first motor passes through the slider and extends to the inside of the fixed tube. The output end of the first motor is fixedly connected to a stirring paddle, and the stirring paddle passes through the fixed tube and extends to the bottom of the fixed tube.

[0011] In one possible design, the driving assembly includes a threaded rod, a fixed block is fixedly provided on the side of the support plate away from the first motor, the bottom of the fixed block is rotatably connected to the top of the threaded rod, and the threaded rod passes through a slider and is threadedly connected to the slider, a second motor is fixedly provided on the top of the base, and the output end of the second motor is fixedly connected to the bottom end of the threaded rod.

[0012] In a possible design, the outer wall of the fixed tube is provided with a thread, and the threaded sleeve of the outer wall of the fixed tube is provided with a sealing cover, and the sealing cover is used to seal the opening of the crushing tank.

[0013] In a possible design, the fixing assembly includes a limit block, which is fixedly arranged at the bottom of the base, and is provided with a groove corresponding to the crushing jar, and the crushing jar is clamped in the groove, and two spring sheets are symmetrically fixed on one side of the limit block, and the sides of the two spring sheets close to each other are in conflict with the crushing jar, and the sides of the two spring sheets close to each other and the inner wall of the groove are provided with rubber pads for anti-slip.

[0014] In a possible design, the base is located at the bottom of the crushing jar and is fixedly provided with a heating block for heating the crushing jar, and the heating block is provided with an electric heating wire for generating heat.

The groove on the fixing component and the two spring sheets thereon are in close contact with the crushing jar to fix the crushing jar.

[0017] Then, the control panel is set to start the second motor to drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the slider, the slider moves downward along the hollow track driven by the threaded rod, so that the upper end of the fixed tube is at the opening of the crushing tank, thereby sealing the crushing tank.
