Description

Technical Field

[0001] This utility model relates to the field of fermentation raw material sampling technology, and in particular to a fermentation raw material sampling device. Background Technology

[0002] In the fermentation industry, raw material sampling is a crucial step in monitoring the fermentation process and ensuring product quality. Traditional sampling methods mostly rely on manual operation, using simple containers to take samples directly from the fermenter or using devices with simple sampling tubes. While these methods can meet basic sampling requirements, they have significant shortcomings in controlling sampling depth, sample volume, and automation.

[0003] While some existing technologies attempt to control sampling depth by adding graduations, these devices are mostly complex in structure, inconvenient to operate, and lack automated control. For example, some devices, although marked with graduations, lack effective positioning and fixing mechanisms, making it difficult to control sampling depth. Furthermore, existing technologies rely heavily on manual experience for sample volume control, lacking automated control methods. This not only reduces sampling efficiency but may also lead to inaccurate sampling due to human factors. These problems make traditional sampling methods insufficient to meet the high-quality, high-efficiency production requirements of modern fermentation industries in terms of accuracy and efficiency. Existing technologies often only partially improve these issues, failing to fundamentally solve them, and may introduce new problems in practical applications, such as maintenance difficulties due to device complexity. These problems highlight the shortcomings of existing technologies in controlling the sampling depth of fermentation raw materials and the urgent need for more efficient sampling devices.

[0004] Given these shortcomings of existing technologies, there is an urgent need for a fermentation raw material sampling device that can control sampling depth and quantity, is easy to operate, and has a high degree of automation, in order to meet the requirements of modern fermentation industry for high-quality and high-efficiency production.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0023] See Figures 1 to 4 This utility model provides a fermentation raw material sampling device, including a scale rod 1, a moving rod 2, a lifting rod 3, and a sampling bucket 4; The movable rod 2 is slidably connected to the scale rod 1, the handle 3 is fixedly set on one side of the movable rod 2, and the sampling bucket 4 is set on one side of the bottom of the movable rod 2; The scale rod 1 is equipped with scale lines; The top of the moving rod 2 is equipped with a positioning plate 201 with a comparison scale; The sampling bucket 4 includes a bucket body 401 and a top cover 402. A sample inlet pipe 11 and an exhaust pipe 12 are provided on one side of the bucket body 401. A micro solenoid valve 13 is connected to the sample inlet pipe 11, and a micro vacuum pump 14 is connected to the exhaust pipe 12. The micro solenoid valve 13 and the micro vacuum pump 14 are both electrically connected to an external controller.

[0024] The sample inlet tube 11 is located at the bottom of the barrel 401, and the exhaust pipe 12 is located at the top of the barrel 401.

[0025] The bottom side of the movable rod 2 is fixedly connected to the side wall of the barrel 401. The handle 3 is L-shaped, and the horizontal part of the handle 3 is fixedly connected to the side wall of the movable rod 2.

[0026] A T-shaped groove 101 is provided on the side wall of the scale rod 1 near the moving rod 2; A T-shaped slider 202 is provided on the top side wall of the moving rod 2 near the scale rod 1; The slider 202 slides and matches the groove 101.

[0027] A horizontal limiting plate 5 is provided on the bottom side wall of the scale rod 1 near the moving rod 2.

[0028] A handle 403 is provided on the top of the cover 402.

[0029] The barrel body 401 and the top cover 402 are connected by threads.

[0030] When using this invention, if sampling is required, hold the handle 3 and send the sampling bucket 4 downward. The limiting plate 5 of the scale rod 1 can abut against the upper edge of the container to ensure stability during sampling. By observing the scale line on the scale rod 1 corresponding to the positioning plate 201, the depth of the fermentation raw material can be determined. When the appropriate sampling depth is reached, the micro solenoid valve 13 and the micro vacuum pump 14 are opened at the same time. The micro vacuum pump 14 will extract the gas in the sampling bucket 4, and the fermentation raw material enters the sampling bucket 4 under negative pressure. After sampling is completed, the micro solenoid valve 13 and the micro vacuum pump 14 are closed at the same time.

[0031] The miniature solenoid valve 13 is used to control the entry of raw materials into the sampling container 4, ensuring the controllability of the sampling process. This improves sampling efficiency and reduces manual intervention. The amount of sample entering the sampling container 4 can also be controlled by adjusting the opening time of the miniature solenoid valve 13.

[0032] The miniature vacuum pump 14 is activated, and the air inside the sampling container 4 is extracted through the exhaust pipe 12 to create a negative pressure environment for the sample to enter. As the air inside the sampling container 4 is expelled, the sample enters the sampling container 4 through the injection pipe 11 under the action of pressure difference.

[0033] When the sample in the sampling container 4 reaches the required amount or the preset sampling time, the external controller will send a signal to close the micro solenoid valve 13, cutting off the sample entry, and at the same time stop the operation of the micro vacuum pump 14, thus completing the sampling process.

[0034] After sampling is completed, lift the handle 3 and pull it up to lift the sampling bucket 4.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
