Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fermented grains sampling, and particularly relates to a white spirit fermented grains sampling device. BACKGROUND

[0002] Microorganisms in fermented grains change constantly during the fermentation process of white spirit, and the physicochemical indexes of the fermented grains need to be detected. Usually, a sampling device is used to take out the fermented grains at a specific position, and then the starch content, sugar content and other physicochemical indexes in the fermented grains are detected in laboratory instruments. These physicochemical indexes can reveal the state of the fermented grains and have a very important guiding role for the fermentation production process of white spirit. However, the physicochemical indexes such as temperature, humidity and gas concentration cannot be detected in the laboratory and can only be detected online.

[0003] Chinese utility model patent CN208766006U discloses a multi-layer digital temperature and humidity fermented grains sampler. The sampler disclosed in the patent has the function of detecting temperature and humidity, and can detect the temperature and humidity of the sampling point online at the same time. However, it cannot detect the important physicochemical indexes such as oxygen and carbon dioxide concentration in the fermented grains online.

[0004] At present, the commonly used method for detecting the gas concentration in fermented grains is to bury a gas sensor in a fixed position in the fermented grains so that the gas sensor is in direct contact with the fermented grains. By using the principle of gas diffusion, the gas in the fermented grains diffuses into the gas sensor, and the electrical signal detected by the gas sensor is transmitted to the outside of the fermented grains through a wire. Since the fermented grains need to be stirred during the fermentation process, it is inconvenient to operate and detect the gas sensor buried in the fermented grains. In addition, a large amount of liquid water is generated during the fermentation process of the fermented grains. The commonly used gas sensor is generally an electrochemical sensor or an infrared sensor. When the gas sensor is in direct contact with the fermented grains, it is difficult to avoid the entry of liquid water into the gas sensor, and the entry of liquid water will cause detection data deviation or even failure. Therefore, this detection method is difficult to apply in actual production, and a new type of white spirit fermented grains sampling device needs to be provided. SUMMARY
