Description

Culture dish for food microorganism detection

Technical Field

The utility model relates to the technical field of food microorganism detection, in particular to a culture dish for food microorganism detection.

Background

The food microbial inspection is one of important indexes for measuring the food sanitation quality and is also one of scientific bases for judging whether the food to be detected is eaten or not. Through food microbiological examination, the food processing environment and the food sanitation condition can be judged, the correct evaluation can be made on the degree of the food polluted by bacteria, and a scientific basis is provided for various sanitation management works.

In the food microbial detection, culture solution is added into food and diluted according to a certain proportion, sample solution is added into a culture dish, and then the sample solution in the culture dish is fully and uniformly mixed, the sample liquid in the culture dish is uniformly stirred mostly by manual shaking, in addition, shaking equipment which can make the culture dish rotate can be used for shaking, particularly, when the shaking equipment is used for shaking, the sample liquid in the culture dish rotates along with the culture dish in the rotating process, but the interior of the sample liquid is kept in a static state relatively, so that the sample liquid cannot be fully mixed, the mixing is mainly realized by the rotation speed change of the culture dish which stops the process after rotating, in addition, the shaking effect can be accelerated by forward and backward rotation of the culture dish, but the working steps required by the effect of fully shaking are complex, the operation is complex, and the time is wasted.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model provides the culture dish for detecting the food microorganisms, which accelerates the shaking speed of the sample liquid in the culture dish, improves the shaking effect, and has simple operation and time saving.

The technical scheme for solving the technical problem of the utility model is as follows:

the utility model provides a culture dish that food microorganism detected usefulness, includes the ware body and ware lid, the ware internal stirring wheel that is provided with the rotation setting, the stirring wheel rotate and set up on the boss, the bottom of the ware body be provided with boss complex recess, just stirring wheel pass through torsional spring with the boss and be connected.

Furthermore, a rotating wheel is arranged on the boss, the stirring wheel is rotatably arranged on the rotating wheel, and the top of the rotating wheel is in contact with the dish cover.

Further, the stirring wheel comprises a plurality of blades, and the blades are vertically arranged plates.

Furthermore, a plurality of guide fins are arranged on two sides of each blade, the inner sides of the guide fins are fixedly arranged with the blades, and the outer sides of the guide fins incline upwards and/or downwards.

The effects provided in the contents of the present invention are only the effects of the embodiments, not all the effects of the present invention, and one of the above technical solutions has the following advantages or advantageous effects:

1. according to the utility model, the stirring wheel is rotationally arranged in the culture dish, the torsion spring is arranged between the stirring wheel and the boss, the rotation of the stirring wheel is limited by the torsion spring, when the culture dish is rotated, the stirring wheel rotates along with the torsion spring, the torsion spring stores energy, after the rotation is stopped, the torsion spring releases the stored energy to drive the stirring wheel to rotate in the opposite direction, and sample liquid in the culture dish is stirred and mixed, so that the stirring speed of the sample liquid is improved, the shaking effect is enhanced, and the repeated stirring of the sample liquid in the culture dish can be realized without reversely rotating the culture dish.

2. The upper and lower position of stirring wheel carries on spacingly through the recess of ware lid with ware body bottom, and convenient to detach stirring wheel is firstly conveniently washd the stirring wheel, secondly can adapt to the condition that does not need the stirring wheel.

3. According to the utility model, the guide fins are arranged on the two sides of the blade of the stirring wheel, so that the sample liquid in the culture dish can be guided in the vertical direction, and the sample liquid is mixed more uniformly.
