Description

Shaking device for food microbial detection

Technical Field

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

Background

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

Food microbiological inspection needs to add the culture solution in to food and dilute according to a certain proportion, add the sample solution in the culture dish, again with the sample solution intensive mixing in the culture dish even, among the prior art, drive the culture dish through shaking even equipment and rotate the even work of shaking of sample solution in order to realize the culture dish, the culture dish is at the pivoted in-process, the sample solution in the dish rotates thereupon but the inside static state that keeps relatively of sample solution, can't reach the intensive mixing, its mixes and stops the slew velocity change of this process again after mainly relying on the culture dish to rotate and reach the purpose of shaking even, can accelerate in addition and shake even effect through the positive and negative rotation to the culture dish, but the work step that reaches the effect needs of fully shaking even is complicated, and is troublesome in operation, waste time.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the utility model provides the shaking device for detecting the food microorganisms, which enhances the shaking effect of the sample liquid in the culture dish and improves the efficiency of the shaking work.

Further, the rotating shaft is arranged at the eccentric position of the rotating disc.

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. the motor drives the rotating disc to rotate, the culture dish placed in the rotating disc rotates along with the rotating disc, the torsion spring stores energy in the rotating process, the torsion spring releases the energy to drive the rotating disc to continuously rotate after the motor stops working, and then the energy is stored in the reverse direction to drive the rotating disc to reversely rotate, so that the rotating disc repeatedly rotates, the shaking-up effect is improved, and the working efficiency is improved.

2. According to the utility model, the dish body and the dish cover of the culture dish can be effectively protected through the stepped rubber pad, so that both the dish body and the dish cover can be attached to the rubber pad, and the damage of the dish body or the dish cover of the culture dish caused by collision is avoided. The culture dish is convenient to take and place by arranging the first notch and the second notch on the rotating disc and the rubber pad.

3. Through pivot and rolling disc eccentric settings, can make the culture dish carry out eccentric rotation, the reinforcing shakes even effect.
