Description

Technical Field

[0001] This invention relates to the field of fermentation sampling equipment technology, specifically to a sampling device for a fermenter. Background Technology

[0002] Doubanjiang (fermented broad bean paste) is a condiment whose main ingredients include broad beans and soybeans, and auxiliary ingredients include chili peppers, sesame oil, and salt. Doubanjiang is a fermented reddish-brown condiment. In the production process of doubanjiang, fermentation tanks are required for fermentation.

[0003] The fermented soybeans in the fermentation tank need to be sampled periodically. Patent CN104833546B discloses a sampling device for the top of a fermentation tank, comprising: an outer tube, vertically sealed and fixed to the top of the fermentation tank; a sampling tube, slidably inserted into the outer tube, with its upper end connected to a sampling system, and a steam inlet on the sampling tube located inside the fermentation tank; and a shut-off device on the sampling tube. Before sterilization begins, the sampling tube is slid relative to the outer tube, exposing the steam inlet to the fermentation tank. When the tank temperature reaches approximately 120 degrees Celsius, the shut-off device of the sampling pipeline is opened. The steam generated during the actual sterilization of the raw materials in the fermentation tank enters the sampling tube through the steam inlet and sterilizes the external pipeline of the sampler, thus eliminating the need for a dedicated steam pipeline.

[0004] Utility model CN220872164U discloses a fermentation sampling device for fermented broad bean paste. The sampling tube is an arc-shaped semi-circular tube structure, installed on the outer side of the center of the sampling rod. One end of the sampling tube is equipped with a cap, and the other end is slidably connected to a baffle. An arc-shaped connecting rod is installed on the side of the baffle and the cap facing the inside of the sampling tube. A rotating structure is provided inside the sampling rod to drive the cap and the baffle to move on the sampling tube. After sampling, the rotating structure reverses, causing the cap and the baffle to move back to their initial position, thus facilitating the removal of the broad bean paste from the sampling tube. Because the baffle is slidably connected to the inner wall of the sampling tube, when the broad bean paste in the sampling tube is removed, the broad bean paste adhering to the inner wall of the sampling tube can also be pushed out, reducing the residue of broad bean paste in the sampling tube. This not only reduces the waste of broad bean paste but also facilitates the subsequent cleaning of the sampling tube.

[0005] The sampling devices in the existing technology have a relatively complex structure in actual use, and there are technical problems such as inconvenience in disassembly and cleaning during the later stages of use. Utility Model Content
