Description

Technical Field

[0001] This utility model relates to the field of microbial detection technology in brewing yeast, and in particular to a rapid microbial detection device for brewing yeast. Background Technology

[0002] Yeast starter is a crucial saccharification and fermentation agent in the brewing process, and its microbial composition directly affects the flavor, quality, and production efficiency of the liquor. Microbial detection in yeast starter aims to analyze the types, quantities, and activities of microorganisms within it, providing a scientific basis for yeast starter quality control, process optimization, and flavor research. We commonly use microscopes to detect yeast starter microorganisms. However, due to the large number of samples, frequent handling of slides and coverslips is necessary, and direct observation and comparison between samples is not possible, which presents a challenge. To better address this issue, we propose a rapid microbial detection device for yeast starter. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid detection device for microorganisms in brewing yeast.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rapid detection device for microorganisms in brewing yeast includes a base plate and a fixing plate. A microscope body and a cylindrical shell are mounted on the base plate. A rotating stage is rotatably connected to the cylindrical shell. A rotating mechanism for driving the rotating stage is installed inside the cylindrical shell. Several placement slots arranged in a circumferential array are opened on the rotating stage. Glass slides are placed in the placement slots. Several connecting rods arranged in a circumferential array are fixed to the side of the fixing plate. A frame is fixed to the connecting rods. A coverslip is fitted inside the frame and covers the glass slide.

[0005] Preferably, the rotating mechanism includes a motor, a first gear, a rotating shaft, and a second gear. The motor is installed inside the cylindrical shell, and the output shaft of the motor is fixedly sleeved with the first gear. The rotating shaft is rotatably installed inside the cylindrical shell and fixed on a rotating platform. The second gear, which meshes with the first gear, is fixedly sleeved on the rotating shaft.

[0006] Preferably, a push rod is slidably sleeved on the rotating platform, a clamping plate is fixed to the top of the push rod, the clamping plate is supported on the bottom of the glass slide, a spring is sleeved on the push rod, and a lever is fixed to the bottom of the push rod.

[0007] Preferably, the side of the frame is threaded with a locking screw, one end of which is rotatably fitted with a clamping plate, and the cover glass is locked inside the frame by the clamping plate.

[0008] Preferably, a guide column is fixed to the top of the rotary table, the guide column slides through the fixed plate, and a handle is fixed to the fixed plate.

[0009] Preferably, a marking plate is fixed on the connecting rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the cover glass is installed and fixed in the frame. By turning the locking screw, the locking screw pushes the clamping plate to clamp the cover glass, thereby locking the cover glass in the frame. The handle is convenient for lifting the fixing plate, and the guide post is used to guide the fixing plate to facilitate the accurate covering of the cover glass on the slide. The marking plate is used to mark the corresponding yeast sample to avoid confusion. 2. In this invention, the yeast samples to be tested are placed on glass slides, and then covers the slides with coverslips. The yeast samples can be observed through the microscope body. The rotating mechanism can drive the rotating stage to rotate on the cylindrical shell, so that yeast samples in different positions can be rotated to the observation position of the microscope body. This allows for rapid observation and comparison of multiple samples with excellent results. After the test is completed, the fixing plate can be lifted to remove the coverslip. Then, by squeezing the lever, the clamping plate can be pushed by the push rod, and the clamping plate can lift the glass slide, which can then be removed for easy cleaning and maintenance.
