Beaten up-type bacterial suspension device having a vibration percussion instrument

摘要

(57) bacterial suspension apparatus useful for microbiological analysis of summary] food, means to seal releasably to the plastic pouch containing the suspending liquid and the test sample in a casing, the interior of the casing and, I have a beating tool hit the outside of the plastic bag at a frequency that is. The vibration frequency is large enough in order to shock wave for suspending the bacteria to be propagated in the liquid collision every tapping device in a bag, the bag do not conform completely to the movement of the tapping tool , and small enough to aid in the removal of bacteria at the time of each collision, went deep be in contact with the bag by a length sufficient percussion instrument is to be transmitted to the test sample liquid and stirring energy. As additional improvement over the prior art, a set tray to prevent dangerous bacterial suspension to reach to the die if the bag leaks, suspension device, not just a part of the beating / suspension mechanism It includes a guard door operator, the operator protection door can be transparent, making it possible to observe the behavior. In addition, the door can be completely removed in order to improve the cleanliness.
